Description

Technical Field

[0001] The utility model belongs to the technical field of exhibition facilities, and in particular relates to a follow-up teleprompter. Background Art

[0002] A teleprompter is an auxiliary facility used to display graphic and text prompts. The displayed graphic and text prompts are for the speaker to read and serve as a prompt. It usually includes a high-brightness display screen. Teleprompters are often used in exhibitions. Exhibitors explain and promote their exhibited products in the form of speeches or on-site explanations at the booths they have built. There are usually two forms of teleprompters in such scenes. One form is floor-standing, that is, the teleprompter is placed on the ground in front of the booth, and the other form is hanging, that is, the teleprompter is hung on the booth truss. Regardless of the application method, the principle is similar. The speaker needs to continuously observe the content on the teleprompter during the speech.

[0003] However, existing teleprompters are usually fixed facilities. After the teleprompter display screen is set to a suitable position and the angle is pre-adjusted, the posture will no longer change. This type of teleprompter has the following problems: the speaker's position is not fixed. As the speech progresses, his position changes at any time. However, due to the position of the teleprompter, the speaker cannot move to a position where he cannot view the prompt normally, which limits the effect of the speech and in some cases causes problems in the middle of the speech. In summary, it is necessary to develop and design a teleprompter facility with follow-up capabilities to solve the aforementioned technical problems. Utility Model Content

[0004] The purpose of the utility model is to provide a follow-up teleprompter, which has the ability to follow the position of a speaker. By controllably following the speaker, the speaker can still obtain a normal prompting effect when moving the position in a larger area.

[0025] The rotary drive device 2 includes two side plates 2-1 arranged opposite to each other, and connecting rods 2-2 are installed between the four corners of the two side plates 2-1. The two side plates 2-1 and the four connecting rods 2-2 together form a frame structure. A guide sleeve 2-3 with a window on the inner side of the middle is installed between the two side plates 2-1. A rack 2-6 is arranged in the guide sleeve 2-3, and the teeth of the rack 2-6 are exposed from the window. When the rack 2-6 is driven, the rack 2-6 reciprocates along the axial direction in the corresponding guide sleeve 2-3. The guide sleeve 2-3 can provide a guiding effect for the aforementioned reciprocating movement of the rack 2-6, improve the stability of the displacement, and the guide sleeve 2-3 can also prevent foreign matter from entering the moving space of the rack 2-6 to cause a jamming problem.

[0026] A support 2-4 is installed on the outer side of the middle of the guide sleeve 2-3, and a base plate 2-7 is installed between the tops of the two supports 2-4. The base plate 2-7 is fixedly connected to the tops of the two supports 2-4 by screws. It also includes a rotary drive motor 2-5, whose drive shaft 2-8 is located in the shaft seat in the middle of the base plate 2-7. A drive gear is also installed at the lower part of the drive shaft 2-8. The drive gear is located between the racks 2-6 on both sides and meshes with the racks 2-6 for transmission. The rotary drive motor 2-5 drives the drive gear to rotate. When the drive gear rotates, the racks 2-6 on both sides thereof move in translation in the guide sleeves 2-3 where they are located, and the movement directions of the two racks 2-6 are opposite.

[0027] The driving shaft 2-8 is exposed through a window arranged in the middle position of the base housing 1.

[0028] See also Figure 3 , we can see that:

[0029] The pitch drive base includes a bottom frame 4, a swing frame 6, and two opposite pitch drive devices 5 installed therebetween. The slewing drive device 2 drives the bottom frame 4 to slew, and the two pitch drive devices 5 drive the swing frame 6 to pitch. In a floor-standing application, the bottom frame 4, the pitch drive device 5, and the swing frame 6 are located above the base box 1.

[0030] The pitch drive device 5 includes a drive frame 5-2 installed on the bottom frame 4, on which a transmission gear set 5-3 and a pitch drive motor 5-1 for inputting power to the transmission gear set 5-3 are installed. The bottom two sides of the swing frame 6 are hingedly connected to the two drive frames 5-2 of the pitch drive devices 5 and driven gears 5-4 are provided at the root positions of the two sides. The driven gears 5-4 are meshed and driven with the transmission gear set 5-2 on this side. The two pitch drive motors 5-1 act synchronously and drive the swing frame 6 forward or backward to realize pitch drive.

[0031] In this embodiment, the bottom frame 4 includes a rectangular bottom outer frame 4-1, a middle cross beam 4-2 is installed in the middle of the bottom outer frame 4-1, the driving frames 5-2 of the two pitch driving devices 5 are installed and fixed in the middle of the two end profiles of the bottom outer frame 4-1, and the pitch driving motor 5-1 is located on the inner side of the bottom outer frame 4-1, and the bottom outer frame 4-1 provides a certain protection for the pitch driving motor 5-1. The middle position of the middle cross beam 4-2 is fixedly connected to the exposed driving shaft 2-8 of the slewing driving device 2.

[0032] In this embodiment, the swing frame 6 includes two opposite swing arms 6 - 1 , and a connecting beam 6 - 2 is installed between the upper ends and the middle parts of the two swing arms 6 - 1 .

[0033] A prompting display screen 7 is installed on the swing frame 6. The back of the prompting display screen 7 is fixedly connected to the swing arm 6-1 and the connecting beam 6-2. The prompting display screen 7 is selected as a highlight display for the current application.

[0034] Embodiment 2

[0035] See also Figure 4 It can be seen that the follow-up teleprompter in this embodiment is a hanging application mode.

[0036] In this embodiment, the base box 1 of the rotary drive base is installed and fixed at the lower end of the suspension rod 8 to form a hanging application. At this time, the bottom frame 4, the pitch drive device 5, the swing frame 6 and the prompt display screen 7 are located below, and the upper end of the suspension rod 8 can be fixedly connected to the booth truss.

[0037] There is no difference in the structure of the follow-up teleprompter in the hanging application mode and the floor-standing application mode. It can be imagined that in the floor-standing application mode, a counterweight block 3 can be set in the base box 1 to improve stability, while in the hanging application mode, there is no need to set a counterweight block 3.

[0038] Taking the floor-standing application as an example, the usage of this follow-up teleprompter is described as follows:

[0039] After the follow-up teleprompter is installed at the exhibition site, the control cable is used to connect the slewing drive motor 2-5, the pitch drive motor 5-1 and the prompt display screen 7 to the exhibition site control system, and the operation and control are performed by the on-site operation and maintenance personnel. Specifically, the on-site operation and maintenance personnel observe the position of the speaker on the stage and perform follow-up control according to the position of the speaker. For example, when the speaker moves to the side, the operation and maintenance personnel operate and control the slewing drive motor 2-5 to make the prompt display screen 7 rotate to the same side to keep facing the speaker. When the speaker gets closer to the teleprompter, the operation and maintenance personnel operate and control the pitch drive motor 5-1 to make the prompt display screen 7 tilt further backward (that is, the angle between the prompt display screen 7 and the horizontal plane is reduced), so that the speaker can more easily view the prompt content.
