[0022] In order to better understand the purpose, structure and function of the present invention, the following will further describe a mobile display support device of the present invention in detail with reference to the accompanying drawings.

[0023] As Figures 1 to 6 shown, a mobile display support device of the present invention includes a base, and batteries 24 are provided on both sides of the base through storage boxes 23. A display screen 21 is provided on the base, and a moving device for moving it is also provided on the base. Among them, the base is composed of a support base 1 and a cover plate 2 detachably provided on its top surface through a connecting member, and the display screen 21 is provided on the cover plate 2. A holding groove 3 is opened on the bottom surface of the support base 1, and the moving device is provided in the holding groove 3 of the support base 1. Specifically, the moving device includes a telescopic device provided on the inner top surface of the holding groove 3 and connected to the battery 24, and the telescopic end of the telescopic device is arranged downward. A connecting frame is provided on the telescopic end of the telescopic device, and a plurality of universal wheels 8 are distributed on the bottom surface of the connecting frame. The connecting frame is supported by the telescopic device, and the universal wheels 8 on the connecting frame extend out of the holding groove 3. When the universal wheels 8 contact the ground, the support base 1 is jacked up by the universal wheels 8 and away from the ground. After that, pushing the support base 1 or the display screen 21 can realize the movement of this support device. Of course, when it is necessary to fix this support device on the ground, control the telescopic device on this support device to drive the connecting frame to retract into the holding groove 3, so that the universal wheels 8 on the connecting frame are retracted into the holding groove 3, and the bottom surface of the support base 1 is supported on the ground. It should be noted that the top end of the storage box 23 is open, and the battery 24 can be put into the storage box 23 through the opening of the storage box 23 for storage.

[0024] The telescopic device in this embodiment is preferably an electric push rod 5, and the electric push rod 5 can be directly connected to the battery 24. Of course, the telescopic device can also be replaced with other telescopic devices, such as air cylinders or hydraulic cylinders, etc., and no more restrictions are made here. The connecting member between the support base 1 and the cover plate 2 is a bolt. A threaded hole for its threaded connection is opened on the support base 1. At the same time, a through hole is opened on the cover plate 2 corresponding to the threaded hole position of the support base 1. The bolt passes through the through hole on the cover plate 2 and is screwed into the threaded hole on the support base 1, and the connection between the top cover 2 and the support base 1 can be realized.

[0025] A fixing component is also provided on the liquid storage tank 3. Through the fixing component, after the support device moves to an appropriate position, the support device can be effectively and stably fixed, preventing others from accidentally touching the support device and causing it to displace, thus affecting others' viewing of the display screen 21. Among them, the fixing component includes a fixing frame 9 provided in the liquid storage tank 3, and the fixing frames 9 are detachably connected to the inner wall of the liquid storage tank 3 by bolts. A connecting cylinder 10 is vertically provided on the fixing frame 9, and a cross frame 101 is coaxially provided on the connecting cylinder 10. A link 12 that can slide up and down is provided at the center position of the cross frame 101, and a support arm 13 is provided on the top surface of the link 12, and the support arm 13 is connected to the connecting frame. At the same time, a sealing disc 14 that cooperates with the bottom surface of the connecting cylinder 10 is provided at the bottom surface of the link 12.

[0026] When the support base 1 descends, the suction cup 11 will first contact the ground, and the air in the suction cup 11 will directly be discharged through the gap between the cross frame 101 and the connecting cylinder 10. During the descent of the suction cup 11, the sealing disc 14 will be lifted upward along with the connecting frame through the link 12 and the support arm 13, and the sealing disc 14 will abut against the bottom surface of the connecting cylinder 10 during the ascent of the sealing disc 14, so as to form a seal between the sealing disc 14 and the connecting cylinder 10. At this time, the suction cup 11 can stably fix the support base 1 on the ground through the connecting cylinder 10, preventing others from moving or toppling the support device accidentally after touching it. When it is necessary to move the support device, it is necessary to control the telescopic device to drive the connecting frame and the universal wheels 8 on the connecting frame to descend, and the support arm 13 connected to the connecting frame will also drive the sealing disc 14 to descend through the link 12. At this time, the air in the suction cup 11 will be discharged through the gap between the sealing disc 14 and the bottom surface of the connecting cylinder 10, so that the suction cup 11 releases the adsorption on the ground, facilitating the suction cup 11 to better disengage from the bottom surface. Among them, the sealing disc 14 for the connecting cylinder 10 is made of rubber material. The rubber sealing disc 14 can make the seal between the sealing disc 14 and the connecting cylinder 10 more airtight.

[0027] As Figure 2 shown, the connecting frame for connecting the telescopic device includes a cross 6 provided at the telescopic end of the telescopic device, and the outer ends of the sides of the cross 6 are connected by a frame 7, and the universal wheels 8 are provided at the four corner positions of the bottom surface of the frame 7. And the support arm 13 is connected to the frame 7. In order to increase the stable connection of the connecting frame relative to the support base 1, limit pins 22 are distributed on the inner top surface of the liquid storage tank 3, and the limit pins 22 are slidably arranged with the cross 6. There are two limit pins 22 symmetrically arranged with the center of the support base 1 in this embodiment, and the two limit pins 22 are respectively slidably arranged with the corresponding cross bar of the cross 6.

[0028] Preferably, a groove 4 is provided on the top surface of the support base 1, and a buffer assembly is provided in the groove 4. By providing the buffer assembly, the display screen can be buffered when the support device is moved, preventing damage to the internal electronic components of the display screen due to vibration. Among them, the display screen 21 includes a limit screen and a bottom plate 20 provided on the bottom surface of the display screen 21. The display screen 21 penetrates through the cover plate 2 and is slidably arranged therewith, and the display screen 21 is connected to the battery 24. And the buffer assembly for buffering and damping the display screen includes a plurality of first shock absorbers 15 provided on the inner bottom surface of the groove 4, and the top surface of each first shock absorber 15 is connected to the bottom surface of the bottom plate 20. At the same time, a first spring 16 is sleeved on the first shock absorber 15 between the bottom plate 20 and the inner bottom surface of the groove 4. When the support device passes through an uneven bottom surface, the support base 1 will vibrate. At this time, the first spring 16 and the first shock absorbers 15 will buffer and absorb the shock of the display screen through the bottom plate 20, reducing the vibration effect of the display screen and protecting the internal electronic components of the display screen.

[0029] As Figure 4 shown, as a further improvement, a buffer device is also provided between the bottom plate 20 and the inner top surface of the groove 4. The buffer device and the buffer assembly can buffer the display screen 21 in two layers, enabling the support device to have a good buffering method and effectively protecting the safety of the display screen 21. Specifically, the buffer device includes an airbag 17 provided between the bottom plate 20 and the inner top surface of the groove 4, and baffles 171 are provided on both sides of the airbag 17. At the same time, a second shock absorber 18 is provided between the baffle 171 and the side wall of the groove 4, and a second spring 19 is sleeved on the first shock absorber 15 between the baffle 171 and the side wall of the groove 4. The display screen 21 presses down the airbag 17 through the bottom plate 20. After the airbag 17 is compressed, it will exert a thrust on the baffle 171. At this time, the second shock absorber 18 and the second spring 19 will be compressed, absorbing the shock force brought by the display screen to the airbag 17, thereby achieving the effect of buffering and absorbing the shock of the display screen.

[0030] Usage method: When it is necessary to move the support device, control the telescopic device to drive the universal wheel 8 to lift upward through the connecting frame. And during the lifting process, the support arm 13 connected to the connecting frame will drive the sealing disc 14 to approach the bottom surface of the connecting cylinder 10 through the connecting rod 12 until a seal is achieved between the sealing disc 14 and the bottom surface of the connecting cylinder 10. At this time, the suction cup 11 will also adsorb the ground, completing the fixation effect of the support device on the ground through the suction cup 11. When it is necessary to move the support device, only need to control the telescopic device to drive the connecting frame and the universal wheel 8 on the connecting frame to move downward, and the connecting frame will also drive the sealing disc 14 to descend through the support arm 13 and the connecting rod 12, so that the sealing disc 14 releases the seal on the bottom surface of the connecting cylinder 10, so that the suction cup 11 can be separated from the bottom surface, facilitating the movement of the support device.
