Description

Technical Field

[0001] This utility model relates to the field of tablet computer display equipment technology, and in particular to a tablet computer lifting and lowering integrated machine. Background Technology

[0002] A tablet computer (or simply tablet) is a small, portable personal computer that uses a touchscreen as its primary input device. Its touchscreen (also known as digitizer technology) allows users to work with a stylus or digital pen without a traditional keyboard or mouse. Users can input via built-in handwriting recognition, an on-screen keyboard, voice recognition, or a physical keyboard (if the model is equipped with one).

[0003] In the tablet sales process, the display stage is crucial, effectively attracting consumers' attention and facilitating customer operation and experience, thereby increasing product exposure and sales conversion rates. However, current display devices generally fix tablets externally, making them impossible to store, and the screen is easily scratched or damaged during transportation or storage.

[0004] Furthermore, many paperless smart meeting scenarios also require the use of tablets, making it essential to address the charging, data transfer, and storage solutions for all tablets in the meeting room. However, existing devices fix tablets in place, preventing angle adjustments and limiting their use to either landscape or portrait mode. This lack of flexibility in adapting to diverse screen display requirements results in suboptimal presentation quality. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a tablet computer lifting and lowering integrated machine, which can realize the stable clamping and safe lifting and lowering storage of tablet computers, and can also perform multi-angle free adjustment and horizontal and vertical screen switching during tablet display, effectively improving the flexibility and safety of tablet display and storage.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A tablet computer lifting device includes a housing and a tablet fixing bracket. The top of the housing has an opening. The tablet fixing bracket is movably installed inside the housing. The tablet fixing bracket is equipped with a movable tablet clamp that can clamp or release the tablet. The movable tablet clamp includes a clamping plate and a clamping plate. The clamping plate and the clamping plate are connected to the tablet fixing bracket through a locking, unlocking and adjusting mechanism. The movable tablet clamp moves upward with the tablet fixing bracket to extend out of the housing after passing through the opening, or moves downward to be stored inside the housing.

[0007] In this embodiment, the movable tablet clamp securely fixes the tablet by clamping it with clamping plate one and clamping plate two. The locking, unlocking, and adjusting mechanism controls the opening and closing of clamping plate one and clamping plate two, facilitating quick clamping or releasing of the tablet. At the same time, the movable tablet clamp can be raised to the outside of the box for display or lowered into the box for storage. While ensuring that the tablet can be displayed normally, it can also effectively avoid damage to the tablet screen during transportation or storage, effectively reducing the risk of equipment damage. It also saves transportation and storage space, greatly improving the portability and safety of the overall equipment.

[0008] Furthermore, the flat plate fixing bracket also includes a support plate. The clamping plate one and the clamping plate two are respectively disposed on opposite sides of the support plate. The clamping plate one is rotatably connected to the support plate through the flat plate rotation shaft. One side of the clamping plate two is provided with a sliding groove that slides with the clamping plate one. The clamping plate two can slide relative to the clamping plate one. The clamping plate two and the clamping plate one are connected by a tension spring.

[0009] The beneficial effects of adopting the above-mentioned further solution are as follows: clamping plate two and clamping plate one are tightly fitted under the action of tension spring, ensuring stable clamping of the tablet. When it is necessary to install or remove the tablet, external force overcomes the elasticity of the tension spring, causing clamping plate two to slide along the slide groove, thereby opening the clamping space and facilitating quick insertion or removal of the tablet. Clamping plate one is connected to the support plate through the tablet rotation axis, which can drive the tablet to rotate in the vertical plane, realizing free switching between horizontal and vertical screens, adapting to different display scenario needs, and improving user experience.

[0010] Furthermore, one end of the plate rotation shaft is fixedly connected to the clamping plate, and the other end of the plate rotation shaft is rotatably connected to the support plate through a damping bearing.

[0011] The beneficial effects of adopting the above-mentioned further solution are: the setting of the damping bearing enables the second clamping plate to have a moderate damping feel during the rotation of the plate along with the first clamping plate, thereby ensuring that the plate can be stably stopped at any angle after rotation, avoiding automatic sliding caused by gravity or external force, effectively improving the ease of operation and display stability of plate angle adjustment; at the same time, the damping bearing has a compact structure, wear resistance, and long service life, and can maintain long-term stability and reliability.

[0012] Furthermore, the locking and unlocking adjustment mechanism includes a locking and unlocking adjustment shaft located on one side of the plate rotation axis and parallel to the plate rotation axis. The locking and unlocking adjustment shaft is rotatably connected to the clamping plate. A triangular cam is provided on the locking and unlocking adjustment shaft. The locking and unlocking adjustment shaft is fixedly connected to the first corner of the triangular cam. A locking pin is provided at the second corner of the triangular cam. An arc-shaped locking groove is provided on the clamping plate, which slides in cooperation with the locking pin. One end of the arc-shaped locking groove is through the plate. When the locking pin rotates with the triangular cam, it slides into or out of the arc-shaped locking groove. An unlocking wheel is also provided at the third corner of the triangular cam. The unlocking wheel separates from or abuts against the clamping plate.

[0013] The beneficial effects of adopting the above-mentioned further solution are as follows: When the locking and unlocking adjustment shaft rotates, the triangular cam rotates accordingly, thereby driving the locking pin to slide into the arc-shaped locking groove. The position of the second clamping plate relative to the first clamping plate is fixed, and the relative sliding between the first clamping plate and the second clamping plate is restricted, thereby achieving the locking of the clamping state and ensuring that the flat plate is stable and does not loosen during use. Conversely, when the locking pin slides out of the arc-shaped locking groove, the second clamping plate can slide freely relative to the first clamping plate. At the same time, the unlocking wheel contacts the second clamping plate during the rotation of the cam and pushes the second clamping plate, so that the second clamping plate overcomes the elastic force of the tension spring and slides relative to the first clamping plate, thereby achieving quick unlocking. The whole operation is simple and convenient and can be completed with one hand.

[0014] Furthermore, the clamping plate is also provided with an elastic rod, which is located in the receiving groove of the clamping plate. A deformation space is provided between the side of the receiving groove away from the triangular cam and the elastic rod. An opening two is provided on the side of the receiving groove near the triangular cam. The size of the opening two is smaller than the length of the elastic rod. The elastic rod abuts against the limiting surface two on the corner side wall of the triangular cam fixing, locking and unlocking adjustment shaft through the opening two.

[0015] The beneficial effects of adopting the above-mentioned further solution are as follows: During the rotation of the triangular cam driven by the locking and unlocking adjustment shaft, one side of the limiting surface two will gradually press against the elastic rod, pushing the elastic rod to compress the elastic potential energy in the deformation space. During this process, the locking pin slides out from the arc-shaped locking groove, and the locking state between clamping plate one and clamping plate two is released. When the triangular cam loses the external force, the elastic rod relies on the stored elastic potential energy to push the triangular cam back to reset, ensuring that the locking pin can automatically slide into the arc-shaped locking groove, thus achieving automatic locking. This structure, through the cooperation of the elastic rod and the limiting surface two, ensures that the system can quickly reset after unlocking, improving operational efficiency and reliability, while avoiding the safety hazard of not locking due to human negligence.

[0016] Furthermore, the support plate is provided with an arc-shaped groove that slides with the end of the locking and unlocking adjustment shaft. The end of the locking and unlocking adjustment shaft that slides with the arc-shaped groove is provided with a lock hole. The arc-shaped groove is provided with a through-hole for unlocking. The unlocking hole is located at one end of the arc-shaped groove and is larger than the lock hole.

[0017] The beneficial effects of adopting the above-mentioned further solution are as follows: When clamping plate one and clamping plate two rotate synchronously, they drive the locking and unlocking adjustment shaft to slide along the arc-shaped groove. Only when clamping plate one and clamping plate two rotate synchronously until the end of the locking and unlocking adjustment shaft is opposite to the unlocking hole in the arc-shaped groove can the external unlocking tool (the key that matches the lock hole) be inserted through the unlocking hole and drive the locking and unlocking adjustment shaft to rotate, thereby driving the triangular cam to rotate, causing the locking pin to disengage from the arc-shaped locking groove. At the same time, the unlocking wheel pushes clamping plate two to achieve manual unlocking. That is, the unlocking hole and the lock hole can only be triggered when clamping plate one and clamping plate two are at a specific angle. This not only improves the anti-theft performance but also ensures the convenience of users in normal use.

[0018] Furthermore, the flat plate fixing bracket also includes an up-and-down movable support seat that slides with the slide rail inside the box. The support plate is installed on the up-and-down movable support seat. The box is provided with a sliding drive mechanism, and the up-and-down movable support seat is connected to the sliding drive mechanism.

[0019] The beneficial effects of adopting the above-mentioned further solution are: the sliding drive mechanism is used to drive the upper and lower moving support base to rise and fall smoothly along the box guide rail, so that the height of the upper and lower moving support base can be precisely adjusted according to the usage requirements, thereby driving the movable flat clamp to rise to the outside of the box for display or to fall into the box for storage.

[0020] Furthermore, the sliding drive mechanism includes a drive motor and a synchronous belt assembly. The synchronous belt assembly includes two parallel synchronous belts, which are fixedly connected to the upper and lower movable support base. The upper and lower ends of the two synchronous belts are respectively connected by synchronous pulleys. A tension pulley is also provided on one side of the synchronous belt. The tension pulley is rotatably connected to the upper and lower movable support base through a tension pulley shaft. The tension pulley abuts against one side of the synchronous belt. The synchronous pulleys at the upper ends of the two synchronous belts are rotatably connected to the housing through a support shaft one. The synchronous pulleys at the lower ends of the two synchronous belts are fixedly connected to both ends of a support shaft two. The two ends of the support shaft two are rotatably connected to the side wall of the housing. A drive gear is fixedly provided on the output shaft of the drive motor. A driven gear is provided on the support shaft two. The drive gear meshes with the driven gear.

[0021] The beneficial effects of adopting the above-mentioned further solution are as follows: when the drive motor starts, it drives the drive gear to rotate. When the drive gear rotates, it drives the driven gear meshing with it to rotate, which in turn drives the second support shaft to rotate. The rotation of the second support shaft drives the two synchronous belts to rotate cyclically with the synchronous belt pulleys connected to the first support shaft through the synchronous belt pulleys, thereby driving the synchronous lifting and lowering of the two sides of the vertical moving support seat connected to the two synchronous belts. The structure is simple and the transmission is stable, effectively avoiding deviation or jamming during the lifting and lowering process.

[0022] Furthermore, the bottom ends of the support plate are respectively hinged to the vertically movable support base, and it also includes an elevation angle adjustment mechanism. The elevation angle adjustment mechanism includes an elevation angle adjustment motor fixed on the vertically movable support base. The output shaft of the elevation angle adjustment motor is fixedly connected to one end of the drive arm, and the other end of the drive arm is movably hinged to a drive component fixed to the bottom of the support plate.

[0023] The beneficial effects of adopting the above-mentioned further solution are as follows: The tilt angle adjustment mechanism is used to adjust the tilt angle of the support plate, allowing the support plate to be adjusted at the required tilt angle, thus improving user comfort and visual experience. During adjustment, the tilt angle adjustment motor starts, driving one end of the drive arm to rotate. As one end of the drive arm rotates, its other end drives the drive component at the bottom of the support plate to rotate the support plate around the point where it is hinged to the vertically movable support seat, thereby realizing the tilt angle adjustment of the flat plate. The structure is simple and the operation is convenient.

[0024] Furthermore, the support plate is also provided with a trigger switch, and an elastic trigger element is provided below the sensing area of ​​the trigger switch. One end of the elastic trigger element is hinged to the trigger switch, and the other end of the elastic trigger element extends to the area below the sensing area of ​​the trigger switch. A mating part is also provided on the clamping plate. When the clamping plate and clamping plate rotate to a horizontal state, the mating part squeezes the elastic trigger element until the elastic trigger element abuts against the sensing area of ​​the trigger switch. The trigger switch is electrically connected to the controller. The elevation angle adjustment motor and the drive motor are electrically connected to the controller through the elevation angle control optocoupler switch and the lifting motor control optocoupler limit switch, respectively.

[0025] The beneficial effects of adopting the above-mentioned further solution are as follows: When the tablet computer rotates to a vertical position with clamping plate one and clamping plate two, the mating component can reach below the elastic trigger and push the elastic trigger to contact the sensing area of ​​the trigger switch. At this time, the controller controls the tilt angle control optical coupling switch to open, and the lifting motor controls the optical coupling limit switch to close, so that the tilt angle adjustment motor rotates, keeping the tablet at a certain tilt angle. At the same time, the drive motor is turned off, ensuring that the tablet will not fall to the top of the cabinet due to misoperation when in a vertical or other arbitrary angle state. When the tablet computer rotates to a horizontal position with clamping plate one and clamping plate two, the mating component cannot contact the elastic trigger. At this time, the elastic trigger cannot contact the sensing area of ​​the trigger switch. At this time, the controller controls the tilt angle control optical coupling switch to close, and the lifting motor controls the optical coupling limit switch to open, so that the tilt angle adjustment motor is turned off and the drive motor is started. The tablet computer can only be in a vertical position. At this time, the drive motor can lift and lower as needed to ensure that the tablet computer can be lowered into the cabinet in a horizontal position for storage. Attached Figure Description

Detailed Implementation

[0028] The principles and features of this utility model are described below. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] Example 1 like Figure 1 and Figure 2 As shown, this embodiment provides a tablet computer lifting all-in-one machine, including a housing 1 and a tablet fixing bracket 2. The top of the housing 1 is provided with an opening 3. The tablet fixing bracket 2 is movably installed in the housing 1. The tablet fixing bracket 2 is provided with a movable tablet clamp 4 that can clamp or release the tablet. The movable tablet clamp 4 includes a clamping plate 401 and a clamping plate 402. The clamping plate 401 and the clamping plate 402 are connected to the tablet fixing bracket 2 through a locking, unlocking and adjusting mechanism 5. The movable tablet clamp 4 moves upward with the tablet fixing bracket 2 to extend outside the housing 1 after penetrating the opening 3, or moves downward to be stored inside the housing 1.

[0032] In this embodiment, the movable tablet clamp 4 securely fixes the tablet by clamping it with clamping plate one 401 and clamping plate two 402. The locking and unlocking adjustment mechanism 5 controls the opening and closing of clamping plate one 401 and clamping plate two 402, facilitating quick clamping or releasing of the tablet. At the same time, the movable tablet clamp 4 can be raised to the outside of the housing 1 for display or lowered into the housing 1 for storage. While ensuring that the tablet can be displayed normally, it can also effectively avoid damage to the tablet screen during transportation or storage, effectively reducing the risk of equipment damage. It also saves transportation and storage space, greatly improving the portability and safety of the overall equipment.

[0033] Example 2 like Figure 2 As shown, based on Embodiment 1, the flat plate fixing bracket 2 in this embodiment further includes a support plate 406. The clamping plate 401 and the clamping plate 402 are respectively disposed on opposite sides of the support plate 406. The clamping plate 401 is rotatably connected to the support plate 406 through the flat plate rotation shaft 407. One side of the clamping plate 402 is provided with a sliding groove 403 that slides with the clamping plate 401. The clamping plate 402 can slide relative to the clamping plate 401. The clamping plate 402 and the clamping plate 401 are connected by a tension spring 404.

[0034] In this embodiment, clamping plate 2 402 and clamping plate 1 401 are tightly fitted together under the action of tension spring 404 to ensure stable clamping of the tablet. When it is necessary to install or remove the tablet, external force overcomes the elasticity of tension spring 404 to make clamping plate 2 402 slide along the slide groove, thereby opening the clamping space for quick insertion or removal of the tablet. Clamping plate 1 401 is connected to support plate 406 through tablet rotation shaft 407, which can drive the tablet to rotate in the vertical plane, realize free switching between horizontal and vertical screens, adapt to different display scenario needs, and improve user experience.

[0035] Example 3 like Figure 2 As shown, based on Embodiment 1, in this embodiment, one end of the flat plate rotating shaft 407 is fixedly connected to the clamping plate 401, and the other end of the flat plate rotating shaft 407 is rotatably connected to the support plate 406 through the damping bearing 405.

[0036] In this embodiment, the damping bearing 405 provides appropriate damping during the rotation of the plate by the clamping plate 402 and the clamping plate 401, ensuring that the plate can remain stably at any angle after rotation and preventing automatic slippage due to gravity or external force. This effectively improves the ease of operation and display stability of the plate angle adjustment. At the same time, the damping bearing 405 has a compact structure, is wear-resistant, and has a long service life, ensuring long-term stability and reliability.

[0037] Example 4 like Figures 3-6 As shown, based on Embodiment 1, the locking and unlocking adjustment mechanism 5 in this embodiment includes a locking and unlocking adjustment shaft 501 located on one side of the plate rotation shaft 407 and parallel to the plate rotation shaft 407. The locking and unlocking adjustment shaft 501 is rotatably connected to the clamping plate 1 401. A triangular cam 502 is provided on the locking and unlocking adjustment shaft 501. The first corner of the locking and unlocking adjustment shaft 501 is fixedly connected to the first corner of the triangular cam 502. A locking pin 503 is provided at the second corner of the triangular cam 502. An arc-shaped locking groove 504 is provided on the clamping plate 2 402, which slides in cooperation with the locking pin 503. One end of the arc-shaped locking groove 504 passes through. When the locking pin 503 rotates with the triangular cam 502, it slides into or out of the arc-shaped locking groove 504. An unlocking wheel 505 is also provided at the third corner of the triangular cam 502. The unlocking wheel 505 separates from or abuts against the clamping plate 2 402.

[0038] In this embodiment, when the locking / unlocking adjustment shaft 501 rotates, the triangular cam 502 rotates accordingly, thereby causing the locking pin 503 to slide into the arc-shaped locking groove 504. The position of the clamping plate 2 402 relative to the clamping plate 1 401 is fixed, and the relative sliding between the clamping plate 1 401 and the clamping plate 2 402 is restricted, thereby achieving the locking of the clamping state and ensuring that the flat plate is stable and does not loosen during use. Conversely, when the locking pin 503 slides out of the arc-shaped locking groove 504, the clamping plate 2 402 can slide freely relative to the clamping plate 1 401. At the same time, the unlocking wheel 505 contacts the clamping plate 2 402 during the rotation of the cam and pushes the clamping plate 2 402, so that the clamping plate 2 402 overcomes the elastic force of the tension spring 404 and slides relative to the clamping plate 1 401, thereby achieving quick unlocking. The whole operation is simple and convenient and can be completed with one hand.

[0039] Example 5 like Figures 3-5 As shown, based on Embodiment 1, in this embodiment, the clamping plate 401 is further provided with an elastic rod 506. The elastic rod 506 is located in the receiving groove 507 of the clamping plate 401. A deformation space 508 is provided between the side of the receiving groove 507 away from the triangular cam 502 and the elastic rod 506. An opening 509 is provided on the side of the receiving groove 507 near the triangular cam 502. The size of the opening 509 is smaller than the length of the elastic rod 506. The elastic rod 506 abuts against the limiting surface 510 on the corner side wall of the locking and unlocking adjustment shaft 501 of the triangular cam 502 through the opening 509.

[0040] The beneficial effects of adopting the above-mentioned further solution are as follows: During the rotation of the triangular cam 502 driven by the locking and unlocking adjustment shaft 501, one side of the limiting surface 510 will gradually press against the elastic rod 506, pushing the elastic rod 506 to compress the elastic potential energy in the deformation space 508. During this process, the locking pin 503 slides out from the arc-shaped locking groove 504, and the locking state between the clamping plate 401 and the clamping plate 402 is released. When the triangular cam 502 loses the external force, the elastic rod 506 uses the stored elastic potential energy to push the triangular cam 502 back to reset, ensuring that the locking pin 503 can automatically slide into the arc-shaped locking groove 504, thus achieving automatic locking. This structure, through the cooperation of the elastic rod 506 and the limiting surface 510, ensures that the system can quickly reset after unlocking, improving operational efficiency and reliability, while avoiding the safety hazard of not locking due to human negligence.

[0041] Example 6 like Figure 6As shown, based on Embodiment 1, the support plate 406 in this embodiment is provided with an arc-shaped groove 511 that slides with the end of the locking / unlocking adjustment shaft 501. The end of the locking / unlocking adjustment shaft 501 that slides with the arc-shaped groove 511 is provided with a lock hole 512. The arc-shaped groove 511 is provided with a through-hole unlocking hole 513. The unlocking hole 513 is located at one end of the arc-shaped groove 511 and is larger than the lock hole 512.

[0042] The beneficial effects of adopting the above-mentioned further solution are as follows: When clamping plate one 401 and clamping plate two 402 rotate synchronously, they drive the locking and unlocking adjustment shaft 501 to slide along the arc groove 511. Only when clamping plate one 401 and clamping plate two 402 rotate synchronously until the end of the locking and unlocking adjustment shaft 501 is opposite to the unlocking hole 513 in the arc groove 511, can the external unlocking tool and the key matching the lock hole 512 be inserted through the unlocking hole 513 and drive the locking and unlocking adjustment shaft 501 to rotate, thereby driving the triangular cam 502 to rotate, so that the locking pin 503 disengages from the arc locking groove 504. At the same time, the unlocking wheel 505 pushes clamping plate two 402 to achieve manual unlocking. That is, the unlocking hole 513 and the lock hole 512 can only be triggered when clamping plate one 401 and clamping plate two 402 are at a specific angle. This not only improves the anti-theft performance, but also ensures the convenience of users in normal use.

[0043] Example 7 like Figure 7 As shown, based on Embodiment 1, the flat plate fixing bracket 2 in this embodiment further includes an up-and-down movable support 6 that slides with the slide rail 9 inside the housing 1. The support plate 406 is installed on the up-and-down movable support 6. The housing 1 is provided with a sliding drive mechanism 7. The up-and-down movable support 6 is connected to the sliding drive mechanism 7 in a transmission manner.

[0044] The beneficial effect of adopting the above-mentioned further solution is that the sliding drive mechanism 7 is used to drive the vertical moving support 6 to rise and fall smoothly along the guide rail of the box 1, so that the vertical moving support 6 can be precisely adjusted in height according to the usage requirements, thereby driving the movable flat clamp 4 to rise to the outside of the box 1 for display or to fall into the box 1 for storage.

[0045] Example 8 like Figure 7 and Figure 9As shown, based on Embodiment 1, the sliding drive mechanism 7 in this embodiment includes a drive motor 701 and a synchronous belt assembly. The synchronous belt assembly includes two parallel synchronous belts 702, which are fixedly connected to the upper and lower movable support 6. The upper and lower ends of the two synchronous belts 702 are respectively connected by synchronous pulleys 704. A tensioning pulley 709 is also provided on one side of the synchronous belts 702. The tensioning pulley 709 is connected to the upper and lower movable support 6 via a tensioning pulley shaft 710. The tensioning wheel 709 is pressed against one side of the synchronous belt 702. The synchronous pulleys 704 at the upper ends of the two synchronous belts 702 are rotatably connected to the housing 1 through the first support shaft 705. The synchronous pulleys 704 at the lower ends of the two synchronous belts 702 are fixedly connected to both ends of the second support shaft 706. The two ends of the second support shaft 706 are rotatably connected to the side wall of the housing 1. A drive gear 707 is fixedly provided on the output shaft of the drive motor 701. A driven gear 708 is provided on the second support shaft 706. The drive gear 707 meshes with the driven gear 708.

[0046] The beneficial effects of adopting the above-mentioned further solution are as follows: When the drive motor 701 starts, it drives the drive gear 707 to rotate. When the drive gear 707 rotates, it drives the driven gear 708 meshing with it to rotate, which in turn drives the second support shaft 706 to rotate. The rotation of the second support shaft 706 drives the two synchronous belts 702 to rotate cyclically with the synchronous belt pulley 704 connected to the first support shaft 705 through the synchronous belt pulley 704. This drives the synchronous lifting and lowering of both sides of the vertical moving support seat 6 connected to the two synchronous belts 702. The structure is simple and the transmission is stable, effectively avoiding deviation or jamming during the lifting and lowering process.

[0047] Example 9 like Figure 7 and Figure 8 As shown, based on Embodiment 1, the bottom ends of the support plate 406 in this embodiment are respectively hinged to the vertically movable support base 6, and it also includes an elevation angle adjustment mechanism 8. The elevation angle adjustment mechanism 8 includes an elevation angle adjustment motor 801 fixed on the vertically movable support base 6. The output shaft of the elevation angle adjustment motor 801 is fixedly connected to one end of the drive arm 802, and the other end of the drive arm 802 is movably hinged to the drive member 803 fixed at the bottom of the support plate 406.

[0048] The beneficial effects of adopting the above-mentioned further solution are as follows: The tilt angle adjustment mechanism 8 is used to adjust the tilt angle of the support plate 406, so that the tilt angle of the support plate 406 can be adjusted as needed, improving user comfort and visual experience. During adjustment, the tilt angle adjustment motor 801 starts, driving one end of the drive arm 802 to rotate. When one end of the drive arm 802 rotates, its other end drives the drive component 803 at the bottom of the support plate 406 to drive the support plate 406 to rotate around the point where it is hinged to the vertically movable support seat 6, thereby realizing the tilt angle adjustment of the flat plate. The structure is simple and the operation is convenient.

[0049] Example 10 like Figures 10-11 As shown, based on Embodiment 1, in this embodiment, the support plate 406 is further provided with a trigger switch 804. Below the sensing area of ​​the trigger switch 804, there is an elastic trigger 805. One end of the elastic trigger 805 is hinged to the trigger switch 804, and the other end of the elastic trigger 805 extends to below the sensing area of ​​the trigger switch 804. The clamping plate 401 is further provided with a mating member 806. When the clamping plate 401 and the clamping plate 402 are rotated to a horizontal state, the mating member 806 presses the elastic trigger 805 until the elastic trigger 805 abuts against the sensing area of ​​the trigger switch 804. The trigger switch 804 is electrically connected to the controller. The elevation angle adjustment motor 801 and the drive motor 701 are electrically connected to the controller through the elevation angle control optocoupler switch 807 and the lifting motor control optocoupler limit switch 711, respectively.

[0050] The beneficial effect of adopting the above-mentioned further solution is that when the tablet computer rotates to a vertical state with the clamping plate 401 and clamping plate 402, the mating part 806 can reach below the elastic trigger 805 and push the elastic trigger 805 to contact the sensing area of ​​the trigger switch 804. At this time, the controller controls the tilt angle control optical coupling switch 807 to open, and the lifting motor controls the optical coupling limit switch 711 to close, so that the tilt angle adjustment motor 801 rotates, so that the tablet computer maintains a certain tilt angle (e.g., ...). Figure 14 As shown), simultaneously, drive motor 701 is turned off to ensure that the tablet will not descend to the top of the housing 1 due to misoperation when in a vertical or other arbitrary angle state; when the tablet rotates to a horizontal state with clamping plate one 401 and clamping plate two 402, mating part 806 cannot contact elastic trigger 805. At this time, elastic trigger 805 cannot contact the sensing area of ​​trigger switch 804. At this time, the controller controls the tilt angle control optical coupling switch 807 to turn off, and the lifting motor controls the optical coupling limit switch 711 to turn on, thereby turning off the tilt angle adjustment motor 801 and starting drive motor 701. The tablet can only be in a vertical state (as shown). Figure 13 As shown in the figure, at this time, the drive motor 701 can lift and lower as needed to ensure that the tablet computer can be lowered into the cabinet 1 in a horizontal state for storage.

[0051] The working principle of this utility model is as follows: The movable tablet clamp 4 achieves stable fixation of the tablet by clamping the first clamping plate 401 and the second clamping plate 402. The locking and unlocking adjustment mechanism 5 is used to control the opening and closing of the first clamping plate 401 and the second clamping plate 402, which facilitates quick clamping or releasing of the tablet. At the same time, the tablet fixing bracket 2 can drive the movable tablet clamp 4 to rise to the outside of the box 1 for display or to fall into the box 1 for storage under the drive of the sliding drive mechanism 7. While ensuring that the tablet can be displayed normally, it can also effectively avoid damage to the tablet screen during transportation or storage, effectively reducing the risk of equipment damage. At the same time, it saves transportation and storage space, greatly improving the portability and safety of the overall equipment.

[0052] Furthermore, the clamping plate 401 is connected to the support plate 406 via the plate rotation shaft 407, which can drive the plate to rotate in the vertical plane, realizing free switching between horizontal and vertical screens, adapting to different display scenarios and improving user experience. The damping bearing 405 provides the clamping plate 402 with moderate damping during the rotation of the plate driven by the clamping plate 401, ensuring that the plate can stably stay at any angle after rotation, avoiding automatic slippage caused by gravity or external force, effectively improving the ease of operation and display stability of plate angle adjustment; at the same time, the damping bearing 405 has a compact structure, is wear-resistant, and has a long service life, maintaining stability and reliability for long-term use.

[0053] Furthermore, through the linkage of the trigger switch 804, the elastic trigger 805, and the mating part 806, combined with the controller's control of the tilt adjustment motor 801 and the drive motor 701, the function switching of the tablet in different clamping states can be realized: when the tablet rotates to a vertical state with the clamping plate one 401 and clamping plate two 402, the mating part 806 separates from the elastic trigger 805, the trigger switch 804 is not triggered, the controller controls the tilt control optical coupling switch 807 to open, the lifting motor controls the optical coupling limit switch 711 to close, thereby controlling the tilt adjustment motor 801 to start, keeping the tablet at the tilt angle, and the drive motor 701 to close, preventing the tablet from being vertical or in other positions. The tablet can be lowered at any angle, causing collision damage. When the tablet rotates to a horizontal position with the clamping plate 401 and clamping plate 402, the mating part 806 moves to the underside of the elastic trigger 805 and pushes the elastic trigger 805 into contact with the sensing area of ​​the trigger switch 804. The controller controls the tilt angle control optical coupling switch 807 to close, and the lifting motor controls the optical coupling limit switch 711 to open, thereby controlling the tilt angle adjustment motor 801 to close and the drive motor 701 to open, ensuring that the tablet is rotated to a horizontal position before it can be lowered for storage. This effectively improves the intelligence level and operational safety of the equipment, and realizes the automatic recognition and response to the display, storage, and rotation status of the tablet.
