DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-7 The utility model discloses a mobile display device for large-screen interaction, including a multimedia terminal 1. The multimedia terminal 1 is a mobile terminal device for large-screen interaction. A top cover 11 is arranged on the top of the multimedia terminal 1, and a circle of air outlet nets 12 is arranged on the bottom of the top cover 11. A fixed plate 15 is arranged inside the multimedia terminal 1, and two air inlet nets 151 are symmetrically embedded inside the fixed plate 15. A rotating plate 16 is movably arranged at the bottom of the fixed plate 15, and a control rod 19 that penetrates the fixed plate 15 and extends to the inside of the multimedia terminal 1 is fixedly arranged on the top of the rotating plate 16. A lifting cylinder 18 is movably clamped on the surface of the control rod 19, and the top of the lifting cylinder 18 is fixedly connected to the bottom of the top cover 11. A switch and a USB port, an HDMI 2.1 port, and a DisplayPort port are integrated on one circle of the multimedia terminal 1.

[0025] Specifically, the inner wall of the multimedia terminal 1 is provided with a circle of isolation grooves 14, and the bottom of the air outlet net 12 is inserted into the isolation grooves 14. The isolation grooves 14 are provided to store the air outlet net 12, thereby preventing dust on the air outlet net 12 from entering the interior of the multimedia terminal 1.

[0026] Specifically, a stabilizing cylinder 141 is provided inside the isolation groove 14, and a stabilizing rod 13 with a bottom end extending into the stabilizing cylinder 141 is provided at the bottom of the top cover 11. The number of the stabilizing rod 13 and the stabilizing cylinder 141 is no less than two, and the stabilizing cylinder 141 cooperates with the stabilizing rod 13 to ensure the stability of the top cover 11 during the lifting process.

[0027] Specifically, a sealing gasket 142 is provided at the top of the isolation groove 14 and is in contact with the inner wall of the multimedia terminal 1. A short enclosure is provided at the bottom of the top cover 11 and is pressed against the sealing gasket 142. With the sealing gasket 142, after the top cover 11 and the multimedia terminal 1 are closed, the short enclosure presses the sealing gasket 142 to ensure the sealing between the top cover 11 and the multimedia terminal 1.

[0028] Specifically, a fan located above the air inlet net 151 is provided on the top of the fixed plate 15. There are two fans, corresponding to the two air inlet nets 151. The fan is started to draw external air into the multimedia terminal 1 through the air inlet net 151 for heat dissipation. The heat-dissipated air is discharged through the air outlet net 12. It is also possible not to use a fan to allow natural convection of the air.

[0029] Specifically, the top of the fixing plate 15 is provided with a connecting tube 17 which is sleeved with the lifting tube 18, the interior of the connecting tube 17 is provided with a spring located at the bottom of the lifting tube 18, the interior of the lifting tube 18 is provided with an L-shaped slide groove 181, the interior of the slide groove 181 is provided with a protrusion 182, and the interior of the control rod 19 is provided with a block 191 which has one end extending into the interior of the slide groove 181 and is engaged with the protrusion 182. When the top cover 11 and the multimedia terminal 1 are closed, the lifting tube 18 descends and compresses the spring. When the lifting tube 18 is lowered, After being lowered into place, the card block 191 slides to the corner of the L-shaped slide groove 181. At this time, the rotating plate 16 is rotated to drive the control rod 19 to rotate, and the control rod 19 drives the card block 191 to slide and engage with the card block 191, locking the lowered top cover 11, and the rotating plate 16 is rotated in the opposite direction to unlock the top cover 11. The compressed spring automatically rebounds and lifts the top cover 11 up. A handle is provided at the bottom of the rotating plate 16, which is convenient for the user to rotate the rotating plate 16. After the rotating plate 16 locks the top cover 11, the air inlet net 151 will be blocked at the same time, ensuring the sealing of the multimedia terminal 1.

[0030] To sum up, in this mobile display device for large-screen interaction, when the multimedia terminal 1 is idle or in transportation, the top cover 11 and the multimedia terminal 1 are closed and the air inlet net 151 is blocked, thereby ensuring the sealing of the multimedia terminal 1. When in use, the rotating plate 16 is rotated to unlock the top cover 11 and the top cover 11 rises, and the large-scale air outlet net 12 greatly improves the heat dissipation effect of the multimedia terminal 1, whether it is starting the fan to dissipate heat or the air is naturally circulated.
