Technical Field

[0001] The utility model relates to the technical field of interactive devices, and particularly relates to a digital media interactive device. Background Art

[0002] Most of the existing digital media interactive devices are realized through touch display screens. Usually, the display screen is fixed to a fixed bracket by a plurality of bolts. During installation, it is necessary to first align the bolt holes on the back of the display screen with the installation holes on the fixed bracket, and then use bolts for installation. Therefore, the existing fixed bracket can only be used for installing a display screen of one size specification, with low practicability, and it is necessary to tighten the bolts one by one, and the installation efficiency is also low; in addition, the fixed bracket cannot be moved after installation, and the angle and height of the display screen cannot be adjusted, and it cannot be applied to different usage situations, having certain limitations. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a digital media interactive device to solve the problems that the display screen of the existing digital media interactive device is troublesome to install and the angle and height of the display screen cannot be flexibly adjusted.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:

[0005] A digital media interactive device includes a base and a clamping mechanism arranged on the base. The clamping mechanism includes a mounting frame and four rotating shafts rotatably connected inside the mounting frame, and the four rotating shafts are arranged in the structure of the four end points of an isosceles trapezoid. Gears are fixedly connected to the four rotating shafts, and the four gears are meshed and connected in sequence from left to right. Clamping rods are coaxially fixed on the four gears, and fixing rods are fixedly connected to the ends of the four clamping rods. A display screen is clamped between the four fixing rods.

[0006] Preferably, a second motor is fixedly installed on one side of the mounting frame, and the output end of the second motor is fixedly connected to one of the rotating shafts.

[0007] Preferably, a rubber sleeve is sleeved outside each fixing rod.

[0008] Preferably, a cylinder is fixed on the base, a sliding seat is slidably connected to the cylinder, a lead screw rotatably connected in the cylinder penetrates through the sliding seat in a screwed manner, and the clamping mechanism is arranged on one side of the sliding seat.

[0009] Preferably, a first motor is fixedly installed in the cylinder, and the output end of the first motor is fixedly connected to one end of the lead screw.

[0010] Preferably, a second connecting rod is connected between the mounting frame and the sliding seat. Two ball head seats are fixedly installed on the mounting frame. Two U-shaped first connecting seats are rotatably connected to the sliding seat. A first electric push rod is rotatably connected to each of the two first connecting seats. A rotating ball head is fixedly installed at one end of each of the two first electric push rods. The two rotating ball heads are respectively rotatably connected in the two ball head seats.

[0011] Preferably, U-shaped second connecting seats are fixedly installed on both the mounting frame and the sliding seat. The second connecting rod is rotatably connected between the two second connecting seats.

[0012] Preferably, the axis of the rotation connection between the second connecting seat fixedly connected to the sliding seat and the second connecting rod is vertically arranged, and the axis of the rotation connection between the second connecting seat fixedly connected to the mounting frame and the second connecting rod is horizontally arranged.

[0013] Preferably, two columns are fixedly installed on the base. A sliding frame is slidably arranged below the sliding seat. Rotating rods are rotatably connected to both sides of the sliding frame. First connecting rods are rotatably connected between the middle parts of the two rotating rods and the sliding seat. One end of each of the two rotating rods is rotatably connected with a pressing block. The two pressing blocks are respectively in contact and cooperation with the two columns.

[0014] Preferably, a second electric push rod is fixedly installed at the bottom of the sliding seat. The telescopic end of the second electric push rod is fixedly connected to the sliding frame.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] (1) The utility model is provided with a clamping mechanism. When driving one of the rotating shafts to make the corresponding gear rotate, through the meshing connection of the four gears in sequence, the rotation directions of two adjacent gears can be made opposite, so that the rotation directions of two adjacent clamping rods are opposite. Thus, when clamping the display screen, the two clamping rods located above drive the corresponding two fixing rods to move downward respectively, and the two clamping rods located below drive the corresponding fixing rods to move upward respectively, so that the four fixing rods tightly press the upper and lower sides of the display screen, thereby realizing the rapid clamping of the display screen. The operation is simple, and it can be used to fix display screens of different sizes and specifications, with high practicability.

[0017] (2) The utility model is provided with a sliding seat. By driving the screw rod to rotate, the slidably connected sliding seat moves up and down on the cylinder, thereby driving the clamping mechanism to move up and down, and further driving the clamped display screen to move up and down. Thus, the height of the display screen can still be adjusted after the display screen is fixedly clamped, which can be applied to different scenarios and increases the practicability.

[0018] (3) The utility model is provided with a first electric push rod and a second connecting rod. When the two first electric push rods extend and retract simultaneously, the display screen rotates along the axis of the rotation connection of the second connecting seat and the second connecting rod arranged horizontally, so as to realize the front-back inclination of the display screen. When one of the two first electric push rods extends and the other retracts, the display screen drives the second connecting rod to rotate along the axis of the rotation connection of the second connecting seat and the second connecting rod arranged vertically, so as to realize the left-right rotation of the display screen. In this way, the display screen can be oriented in different directions by the extension and retraction of the two first electric push rods, which can be applied to different scenarios and increase the practicability.

[0019] (4) The utility model is provided with a carriage, a first connecting rod, a rotating rod, a pressing block and a column. After the sliding seat rises to the required height, the second electric push rod is started to push the carriage away from the sliding seat, so that the rotating rod rotates around the end of the first connecting rod, and thus the pressing block at the other end of the rotating rod abuts against the column. In this way, the pressing block and the rotating rod can play a partial supporting role on the sliding seat and the clamping mechanism, thereby reducing the load on the thread of the lead screw and improving the service life.

Detailed Description of the Invention

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0027] Please refer to Figures 1 - 5 as shown, the present utility model provides the following technical solutions:

[0028] A digital media interaction device includes a base 1 and a clamping mechanism disposed on the base 1. The clamping mechanism includes a mounting frame 13 and four rotating shafts 24 rotatably connected within the mounting frame 13. The four rotating shafts 24 are arranged in the structure of the four end points of an isosceles trapezoid. A gear 23 is fixedly connected to each of the four rotating shafts 24. The four gears 23 are meshed and connected in sequence from left to right. A clamping rod 5 is coaxially fixed to each of the four gears 23. A fixing rod 6 is fixedly connected to the end of each of the four clamping rods 5. A display screen 4 is clamped between the four fixing rods 6;

[0029] A second motor 22 is fixedly installed on one side of the mounting frame 13. The output end of the second motor 22 is fixedly connected to one of the rotating shafts 24.

[0030] Based on the above disclosed structure, when building the digital media interaction device:

[0031] It is necessary to clamp the display screen 4 used for human-computer interaction within the clamping mechanism. The specific operation is as follows: First, support the bottom edge of the display screen 4 on the two fixing rods 6 located below. Then, start the second motor 22 to drive one of the rotating shafts 24 to rotate, thereby driving the corresponding gear 23 to rotate. The four rotating shafts 24 are arranged in the structure of the four end points of an isosceles trapezoid (as Figure 5 shown), and the four gears 23 on the four rotating shafts 24 are meshed and connected in sequence from left to right. Thus, the rotation directions of two adjacent gears 23 are opposite. When clamping the display screen 4, the two gears 23 located in the lower left corner and the upper right corner rotate clockwise, and the two gears 23 located in the upper left corner and the lower right corner rotate counterclockwise. Thus, the rotation of the four gears 23 causes the ends of the four clamping rods 5 to move in the vertical direction towards the direction close to the mounting frame 13, that is, towards the middle. In this way, the four fixing rods 6 all move towards the middle, thereby fixedly clamping the display screen 4 between the four fixing rods 6, thus realizing the construction of the digital media interaction device, with simple operation and high efficiency.

[0032] Preferably, a rubber sleeve is sleeved outside each fixing rod 6. Based on this, the rubber sleeve can increase the friction between the fixing rod 6 and the edge of the display screen 4, so as to facilitate better fixing. At the same time, the rubber sleeve has a certain buffering effect to prevent the display screen 4 from being damaged due to excessive clamping force.

[0033] In addition, regarding the lifting of the display screen 4, a cylinder 2 is fixed on the base 1. A sliding seat 10 is slidably connected to the cylinder 2. A lead screw 19 that is rotationally connected and penetrates through the sliding seat 10 is rotatably connected inside the cylinder 2. The clamping mechanism is arranged on one side of the sliding seat 10; a first motor 18 is fixedly installed inside the cylinder 2, and the output end of the first motor 18 is fixedly connected to one end of the lead screw 19. Based on this, by starting the first motor 18 to drive the lead screw 19 to rotate, the slidably connected sliding seat 10 moves upward along the cylinder 2, thereby driving the clamping mechanism to move upward, and further driving the display screen 4 to move upward; conversely, starting the first motor 18 to drive the lead screw 19 to rotate in the reverse direction causes the display screen 4 to move downward. In this way, the display screen 4 can be moved to any height, so as to be applicable to different interaction scenarios and increase the practicality.

[0034] Furthermore, regarding the adjustment of the orientation of the display screen, preferably, the following structure is provided:

[0035] A second connecting rod 15 is connected between the mounting frame 13 and the sliding seat 10. Two ball head seats 21 are fixedly installed on the mounting frame 13. Two U-shaped first connecting seats 11 are rotatably connected to the sliding seat 10. A first electric push rod 12 is rotatably connected inside each of the two first connecting seats 11. One end of each of the two first electric push rods 12 is fixedly installed with a rotating ball head 20, and the two rotating ball heads 20 are respectively rotatably connected inside the two ball head seats 21;

[0036] U-shaped second connecting seats 14 are fixedly installed on both the mounting frame 13 and the sliding seat 10. The second connecting rod 15 is rotatably connected between the two second connecting seats 14;

[0037] The axis of the rotational connection between the second connecting seat 14 fixedly connected to the sliding seat 10 and the second connecting rod 15 is vertically arranged, and the axis of the rotational connection between the second connecting seat 14 fixedly connected to the mounting frame 13 and the second connecting rod 15 is horizontally arranged.

[0038] As can be seen from the above, when the display screen 4 needs to tilt forward and backward, two first electric push rods 12 are simultaneously activated to extend their telescopic ends. Since the axis of the rotational connection between the second connecting seat 14 and the second link 15 fixedly connected to the sliding seat 10 is vertically arranged, the second link 15 does not rotate. The rotating ball heads 20 at the ends of the two first electric push rods 12 rotate within the two ball head seats 21 respectively, and at the same time, the upper half of the mounting bracket 13 is pushed forward through the ball head seats 21. The second link 15, through the second connecting seat 14 fixedly connected to the mounting bracket 13, makes the lower half of the mounting bracket 13 unable to move forward, so that the second connecting seat 14 fixedly connected to the mounting bracket 13 rotates at the end of the second link 15, thereby making the mounting bracket 13 tilt forward in the vertical direction, and thus making the display screen 4 tilt forward; conversely, when the two first electric push rods 12 are simultaneously activated to retract their telescopic ends, the display screen 4 tilts backward;

[0039] When the display screen 4 needs to rotate left and right, due to the limitation of the axis direction at the connections between the two second connecting seats 14 and the two ends of the second link 15, the heights of the two ball head seats 21 on the mounting plate 13 are always the same. Therefore, when the two first electric push rods 12 are simultaneously activated, one extends its telescopic end and the other retracts its telescopic end, and the heights of the two ball head seats 21 remain unchanged. As a result, the connection end between the second connecting seat 14 fixedly connected to the mounting bracket 13 and the second link 15 does not rotate, and at the same time, the two sides of the upper half of the mounting plate 13 move forward and backward respectively, making the second link 15 rotate within the second connecting seat 14 fixedly connected to the sliding seat 10, causing the mounting bracket 13 to rotate around the vertically arranged connection axis, and further driving the display screen 4 to rotate left and right;

[0040] In summary, by the telescoping of the two first electric push rods 12, the display screen 4 can be tilted in the front-back direction and rotated in the left-right direction, so that the display screen 4 can face different directions, thereby being applicable to different interaction scenarios and increasing the practicality.

[0041] In addition, to increase the service life of the lead screw 19, the following structure is preferably provided:

[0042] Two columns 3 are fixedly installed on the base 1. A sliding frame 17 is slidably arranged below the sliding seat 10. Rotating rods 8 are rotatably connected to both sides of the sliding frame 17. First links 9 are rotatably connected between the middle parts of the two rotating rods 8 and the sliding seat 10. One ends of the two rotating rods 8 are rotatably connected to abutting blocks 7, and the two abutting blocks 7 are in abutting cooperation with the two columns 3 respectively;

[0043] A second electric push rod 16 is fixedly installed at the bottom of the sliding seat 10, and the telescopic end of the second electric push rod 16 is fixedly connected to the sliding frame 17.

[0044] As can be seen from the above, after the sliding seat 10 rises to the required height, the second electric push rod 16 is activated to push out the telescopic end, so that the carriage 17 moves away from the sliding seat 10, thereby driving one end of the two rotating rods 8 away from the sliding seat 10, causing the two rotating rods 8 to rotate around the bottom ends of the two first connecting rods 9 respectively, and causing the other ends of the two rotating rods 8 to drive the two pressing blocks 7 to press against the two columns 3 respectively. In this way, the frictional force between the two pressing blocks 7 and the two columns 3 can provide partial supporting force for the sliding seat 10 through the rotating rods 8, the first connecting rods 9, the carriage 17 and the second electric push rod 16, which can prevent the gravity of the sliding seat 10 and the display screen 4 on the clamping mechanism from being all applied to the thread of the lead screw 19 for a long time, thereby increasing the service life of the lead screw 19.

[0045] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
