The stand does not allow for operation on the tablet, so users need to get close to the tablet to operate it while watching videos. Summary of the Invention

[0005] Therefore, the present invention provides a mobile phone holder for a handheld tablet computer to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a mobile phone holder for a handheld tablet computer, comprising a connecting frame, a concave frame fixedly connected to the back of the connecting frame, and a bottom frame fixedly connected to the bottom of the connecting frame; a guide rod slidably connected to the top of the connecting frame, a clamping spring fixedly connected to the side wall of the guide rod, and the other end of the clamping spring fixedly connected to the top of the connecting frame; the top of the guide rod fixedly connected to an upper clamping plate; a clamping space is formed between the upper clamping plate and the bottom frame for clamping the tablet computer; a contact plate is rotatably connected to the inner side wall of the concave frame, the contact plate is fixedly connected to a worm wheel on a worm gear, the worm gear is rotatably connected to the side wall of the concave frame, and the worm on the worm gear is fixedly connected to a handle; a column is bolted to the back side wall of the connecting frame, and a control box is provided at the upper end of the column, containing a controller and a battery.

[0007] Preferably, a drive motor is bolted to the column, the output shaft of the drive motor is fixedly connected to the L-shaped plate, and an electric push rod is bolted to the side wall of the L-shaped plate. The telescopic end of the electric push rod is slidably connected to the inside of the L-shaped plate.

[0008] Preferably, the telescopic end of the electric push rod is fixedly connected to the moving rod, the moving rod is fixedly connected to the sliding plate, and an arc-shaped contact plate is fixedly connected to the side wall of the sliding plate.

[0009] Preferably, a torque motor is bolted to the upper side wall of the sliding plate, and the output shaft of the torque motor drives the crossbar to rotate and connect with the side wall of the sliding plate. A contact rod is vertically connected to the side wall of the crossbar.

[0010] Preferably, the end of the contact rod is flexibly designed and contains a pressure sensor.

[0011] Preferably, a piston groove is provided on the inner side wall of the connecting frame, and a piston plate is slidably connected in the piston groove.

[0012] Preferably, the other end of the piston plate is fixedly connected to the force-bearing rod, and the other end of the force-bearing rod slides through a groove provided on the side wall of the connecting frame.

[0013] Preferably, the side wall of the connecting frame is provided with an exhaust one-way valve and an intake one-way valve.

[0014] Preferably, a liquid storage tank is provided at both the upper and lower ends of the connecting frame, and a heat-conducting plate is provided in the liquid storage tank. The other end of the heat-conducting plate is connected to the piston groove.

[0015] Preferably, the arc-shaped contact plate and the force-bearing rod are at the same height.

[0016] The beneficial effects of this invention are: This invention utilizes a contact plate rotatably connected to the inner wall of a concave frame. By rotating the handle, a worm gear drives the contact plate to rotate outward and unfold, forming a certain angle with the back of the connecting frame. At this point, the contact plate and the bottom of the concave frame together form a stable support surface. The arc-shaped area at the bottom can contact the tabletop, providing stable support for the bracket and making it convenient to place the bracket on the table for use. Furthermore, the worm gear mechanism has a self-locking characteristic, which can effectively prevent the contact plate from accidentally swinging back during use, further ensuring the stability of the support.

[0017] This invention controls a drive motor to rotate an L-shaped plate, causing a contact rod to rotate forward until it is perpendicular to the connecting frame. Then, an electric push rod is controlled to move a sliding plate, adjusting the distance between the contact rod and the tablet computer fixed to the connecting frame. A torsion motor is then controlled to rotate a crossbar, further driving the contact rod to rotate. This allows the end of the contact rod to slide into contact with the tablet computer's surface. When the torsion motor rotates the contact rod clockwise, it slides downwards to contact the tablet computer's surface; when it rotates counterclockwise, it slides upwards to contact the tablet computer's surface. This simulates the up-and-down movement of a human hand on a tablet computer, facilitating user control of video updates while browsing platforms like TikTok and enriching the user's interactive experience.

[0018] In this invention, the control contact rod is perpendicular to the tablet computer, and then the electric push rod is controlled to drive the sliding plate to move back and forth, so that the sliding plate drives the front end of the contact rod to continuously contact and separate from the tablet computer surface, simulating the continuous clicking of a human finger on the tablet computer screen, which can be used to like videos.

[0019] When the sliding plate in this invention moves back and forth, its arc-shaped contact plate presses against the force rod. The force rod stretches the auxiliary spring and pushes the piston plate to move. The piston plate compresses air and delivers it to the back of the tablet computer through the exhaust one-way valve to help dissipate heat. When the piston plate returns to its original position, it draws air from the rear of the tablet computer through the intake one-way valve. This cycle repeats, and while simulating a click operation, it passively creates a forced airflow on the back of the tablet computer, effectively improving the heat dissipation of the tablet computer and preventing performance degradation or damage due to overheating.

Detailed Implementation

[0022] To further explain the technical solution of the present invention, a detailed description is provided below through specific embodiments.

[0023] like Figure 1 As shown, the present invention provides a mobile phone holder for a handheld tablet computer, including a connecting frame 1. The main body of the mobile phone holder is a connecting frame 1 for supporting and fixing the tablet computer. A concave frame 101 is fixedly connected to the back of the connecting frame 1 to form a back support structure. A bottom frame 2 is fixedly connected to the bottom of the connecting frame 1. A guide rod 4 is slidably connected to the top of the connecting frame 1. A clamping spring 41 is fixedly connected to the side wall of the guide rod 4. The other end of the clamping spring 41 is fixedly connected to the top of the connecting frame 1. The top of the guide rod 4 is fixedly connected to an upper clamping plate 3. In use, the user pulls the upper clamping plate 3 upward to compress the clamping spring 41, places the tablet computer in, and then releases it. The tablet computer is automatically clamped and fixed under the action of the spring force. The upper clamping plate 3 and the bottom frame 2 form a clamping space for clamping the tablet computer. The surfaces of the upper clamping plate 3 and the bottom frame 2 are provided with a rubber layer to increase friction and prevent scratching the device. Please refer to Figures 1 to 7 A contact plate 5 is rotatably connected to the inner wall of the concave frame 101. The contact plate 5 is fixedly connected to the worm gear 6, which is rotatably connected to the side wall of the concave frame 101. The worm on the worm gear 6 is fixedly connected to the handle 7. When the bracket needs to be placed on a table for use, the user rotates the handle 7, which drives the contact plate 5 to rotate outward through the worm gear 6, so that it forms a certain angle with the back of the connecting frame 1. At this time, the contact plate 5 and the bottom of the concave frame 101 together form a stable support surface, and the arc-shaped area 51 at its bottom can contact the table, providing stable support. The worm gear mechanism has a self-locking characteristic, which can prevent the contact plate 5 from accidentally swinging back during use.

[0024] Please refer to Figures 1 to 7 The back side wall of the connecting frame 1 is bolted to a column 8. A control box 9 is provided at the top of the column 8. The control box 9 contains a controller and a battery. The controller is equipped with a 5G transmission module, which allows users to connect to the controller via mobile devices. The control box 9 is equipped with a USB charging port, which is convenient for charging the battery. Specifically, a drive motor 10 is bolted to the column 8. The output shaft of the drive motor 10 is fixedly connected to the L-shaped plate 11. An electric push rod 12 is bolted to the side wall of the L-shaped plate 11. The telescopic end of the electric push rod 12 is slidably connected to the inside of the L-shaped plate 11. The telescopic end of the electric push rod 12 is fixedly connected to the moving rod 13. The moving rod 13 is fixedly connected to the sliding plate 14. An arc-shaped contact plate 141 is fixedly connected to the side wall of the sliding plate 14. The drive motor 10 can drive the L-shaped plate 11 to reciprocate approximately 180 degrees in the horizontal plane, thereby realizing the switching of the entire actuator between the "working position" and the "retracted position". Specifically, a torsion motor 15 is bolted to the upper side wall of the sliding plate 14. The output shaft of the torsion motor 15 drives the crossbar 16 to rotate and connect with the side wall of the sliding plate 14. A contact rod 17 is vertically connected to the side wall of the crossbar 16. The end of the contact rod 17 is flexibly set and has a pressure sensor inside. Its end is wrapped with silicone to detect the contact force with the screen and prevent excessive pressure.

[0025] Specifically, a piston groove 19 is provided on the inner side wall of the connecting frame 1, and a piston plate 20 is slidably connected in the piston groove 19. The other end of the piston plate 20 is fixedly connected to the force rod 18, and the other end of the force rod 18 slides through the slide groove 181 provided on the side wall of the connecting frame 1.

[0026] Please refer to Figures 1 to 7 The side wall of the connecting frame 1 is provided with an exhaust one-way valve 22 and an intake one-way valve 23; A liquid storage tank 24 is provided at both the upper and lower ends of the connecting frame 1. A heat-conducting plate 25 is provided in the liquid storage tank 24. The other end of the heat-conducting plate 25 is connected to the piston groove 19. The arc-shaped contact plate 141 is at the same height as the force-bearing rod 18, which makes it convenient for the arc-shaped contact plate 141 to apply a squeezing force to the force-bearing rod 18 when it moves, and to drive the force-bearing rod 18 to move. The position of the arc-shaped contact plate 141 is at the same height as the extended end of the force rod 18. When the automatic operating mechanism executes the "click simulation" function and the sliding plate 14 drives the arc-shaped contact plate 141 to move back and forth, the arc-shaped contact plate 141 will squeeze the end of the force rod 18 during its forward movement. The force rod 18 is pushed inward, overcoming the elastic force of the auxiliary spring 21, and driving the piston plate 20 to move inward in the piston groove 19. This compresses the air in the piston groove 19 and discharges it through the exhaust one-way valve 22. The discharged airflow is guided to the back area of ​​the clamped tablet computer to help dissipate heat. When the sliding plate 14 moves backward and the arc-shaped contact plate 141 disengages from the force rod 18, the piston plate 20 returns to its original position under the restoring force of the auxiliary spring 21. At this time, the intake one-way valve 23 opens, drawing air from the back area of ​​the tablet computer into the piston groove 19. This cycle repeats, passively creating forced airflow on the back of the tablet computer while simulating a click operation.

[0027] This invention provides a mobile phone stand for a handheld tablet computer. When using the stand, the worm gear 6 is rotated by twisting the handle 7, and the worm gear 6 drives the contact plate 5 to rotate, so that the contact plate 5 and the connecting frame 1 are set at an angle. Then, the connecting frame 1 and the arc-shaped area 51 at the bottom of the concave frame 101 contact the table and restrict the stand on the table. Alternatively, the user can hold the contact plate 5 with their hand. Then pull the upper clamping plate 3 upward and place the tablet computer in the connecting frame 1. Then release the pull on the upper clamping plate 3, and the upper clamping plate 3 will move downward and restrict the tablet computer between the upper clamping plate 3 and the bottom frame 2. The drive motor 10 is controlled to rotate the L-shaped plate 11, causing the L-shaped plate 11 to rotate the contact rod 17 forward until it is perpendicular to the connecting frame 1. Then, the electric push rod 12 is controlled to move the sliding plate 14 to adjust the distance. The sliding plate 14 moves the contact rod 17 to adjust and fix the tablet computer on the connecting frame 1. The torque motor 15 is controlled to rotate the crossbar 16, and the crossbar 16 drives the contact rod 17 to rotate, so that the end of the contact rod 17 contacts and slides with the surface of the tablet computer. When the torque motor 15 drives the contact rod 17 to rotate clockwise, the contact rod 17 can slide downward to contact the surface of the tablet computer. When the contact rod 17 rotates counterclockwise, it can slide upwards to contact the surface of the tablet computer, simulating the human hand sliding up and down on the tablet computer. This allows users to control video updates by rotating the contact rod 17 while browsing Douyin. Then, control the contact rod 17 to be perpendicular to the tablet computer, and control the electric push rod 12 to drive the sliding plate 14 to move back and forth, so that the sliding plate 14 drives the front end of the contact rod 17 to continuously contact and separate from the tablet computer surface, and simulate the human finger clicking on the tablet computer screen. When the sliding plate 14 moves back and forth, the contact plate 141 on the sliding plate 14 can press the force rod 18, the force rod 18 stretches the auxiliary spring 21, the force rod 18 pushes the piston plate 20 to move, the piston plate 20 compresses air and delivers it to the back end area of ​​the tablet computer through the exhaust one-way valve 22, and then when the piston plate 20 returns to its original position, it draws air from the rear end area of ​​the tablet computer through the intake one-way valve 23 and drives the air flow in the rear end area of ​​the tablet computer. Furthermore, the air inside the piston groove 19 is pre-cooled by the cooling liquid in the liquid storage tank 24, which can reduce the temperature of the air inside the piston groove 19. When not in use, the control drive motor 10 drives the L-shaped plate 11 to rotate backward, and the L-shaped plate 11 drives the whole to move backward to the rear end of the connecting frame 1.

[0028] The present invention uses a contact plate 5 rotatably connected to the inner wall of a concave frame 101. By rotating the handle 7, the contact plate 5 is driven to rotate outward and unfold using a worm gear 6, so that it forms a certain angle with the back of the connecting frame 1. At this time, the contact plate 5 and the bottom of the concave frame 101 together form a stable support surface. The arc-shaped area 51 at its bottom can contact the table, providing a stable support for the bracket and making it convenient to place the bracket on the table for use. In addition, the worm gear mechanism has a self-locking characteristic, which can effectively prevent the contact plate 5 from accidentally swinging back during use, further ensuring the stability of the support.

[0029] When using this invention, the user pulls the upper clamping plate 3 upward to compress the clamping spring 41, places the tablet computer in, and then releases it. The upper clamping plate 3 will then automatically move downward under the action of the spring force, clamping and fixing the tablet computer between the upper clamping plate 3 and the bottom frame 2. The operation is very convenient. In addition, the surfaces of the upper clamping plate 3 and the bottom frame 2 are provided with a rubber layer, which can increase the friction between the upper clamping plate 3 and the tablet computer, prevent the tablet computer from slipping, and prevent scratches on the device, thus protecting the appearance of the tablet computer.

[0030] This invention controls the drive motor 10 to rotate the L-shaped plate 11, causing the contact rod 17 to rotate forward until it is perpendicular to the connecting frame 1. Then, the electric push rod 12 is controlled to move the sliding plate 14, adjusting the distance between the contact rod 17 and the tablet computer fixed on the connecting frame 1. Next, the torsion motor 15 is controlled to rotate the crossbar 16, which in turn drives the contact rod 17 to rotate, so that the end of the contact rod 17 contacts and slides against the surface of the tablet computer. When the torsion motor 15 drives the contact rod 17 to rotate clockwise, the contact rod 17 can slide downward to contact the surface of the tablet computer; when the contact rod 17 rotates counterclockwise, the contact rod 17 can slide upward to contact the surface of the tablet computer, thereby simulating the up and down sliding of a human hand on the tablet computer, making it convenient for users to control video updates when browsing videos such as TikTok, and enriching the user's interactive experience.

[0031] In this invention, the control contact rod 17 is perpendicular to the tablet computer, and the electric push rod 12 is controlled to drive the sliding plate 14 to move back and forth, so that the sliding plate 14 drives the front end of the contact rod 17 to continuously contact and separate from the tablet computer surface, simulating the continuous clicking of a human finger on the tablet computer screen, which can be used to like videos.

[0032] When the sliding plate 14 moves back and forth in this invention, the arc-shaped contact plate 141 on it will squeeze the force rod 18. The force rod 18 stretches the auxiliary spring 21 and pushes the piston plate 20 to move. The piston plate 20 compresses air and delivers it to the back area of ​​the tablet computer through the exhaust one-way valve 22 to help the tablet computer dissipate heat. When the piston plate 20 returns to its original position, it draws air from the rear area of ​​the tablet computer through the intake one-way valve 23. This cycle repeats, and while simulating a click operation, it passively forms a forced airflow on the back of the tablet computer, which effectively improves the heat dissipation effect of the tablet computer and prevents the tablet computer from experiencing performance degradation or damage due to overheating.

[0033] In this invention, the air in the piston groove 19 is pre-cooled by the cooling liquid in the liquid storage tank 24, which can reduce the temperature of the air entering the back area of ​​the tablet computer, further enhancing the heat dissipation capacity and ensuring that the tablet computer can maintain good performance during long-term use.

[0034] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
