Description

Technical Field

[0001] The utility model belongs to the technical field of exhibition facilities, and in particular relates to an interactive expression device for an exhibition explanation robot. Background Art

[0002] Exhibitions are a kind of publicity activities to showcase products and technologies, expand channels, promote sales, and spread brands. Usually, the exhibition theme is constructed in the exhibition hall, and the exhibition atmosphere is created. Merchants rent booths in the exhibition hall and design booths according to the characteristics of their own products to achieve the best exhibition effect. Attracting exhibitors to stop in front of the booth is an important means to promote product display and sales. Only when exhibitors stay in the booth for a longer time, merchants will have more opportunities to promote products to achieve more advertising effects and promote sales.

[0003] In order to achieve the above-mentioned effects, it is an important means to set up a series of facilities around the booths to interact with exhibitors. For example, it is an effective means to configure an explanation robot at the exhibition site. The explanation robot can use voice, video and other methods to explain the exhibits and services. However, since the explanation robot executes programmed set instructions, the interaction effect with exhibitors is limited. Some explanation robots also achieve the effect of expression interaction by displaying anthropomorphic expressions on the display screen. However, since the display screen is usually flat, the expression interaction link is not vivid and affects the exhibitors' experience. In summary, it is necessary to develop and design an interactive expression device based on an explanation robot. Utility Model Content

[0004] The utility model aims to provide an interactive expression device for an exhibition explanation robot, which solves the drawbacks existing when using a flat display screen for expression interaction, makes the interactive expression more vivid and improves the experience of exhibitors.

[0006] Preferably, three projection areas are provided on the mask, arranged in an inverted triangle, the two upper projection areas are used to project eye patterns, and the lower projection area is used to project mouth patterns.

[0007] Preferably, the frame of the projection expression component includes two opposite side panels, a rear end panel is installed between the rear ends of the two side panels, a front end panel is installed between the front ends, the light source is installed on the rear end panel, the fixed lens is installed on the front end panel, a rear partition panel and a front partition panel are installed between the middle parts of the two side panels, and light-transmitting windows are provided on the rear partition panel and the front partition panel.

[0008] Preferably, a light source lens is mounted behind the rear partition and in front of the light source using a bracket.

[0009] Preferably, the rotary drive assembly includes a rotary motor mounted on the front partition, and the center of the expression turntable is fixedly connected to the output shaft of the rotary motor.

[0010] Preferably, the shift assembly includes a moving base mounted on the front partition plate and a shift motor driving the moving base to move forward and backward, and the movable lens is mounted and fixed on the moving base.

[0012] Preferably, a speaker hole is provided on the side of the body and a speaker is installed inside the speaker hole, a display screen is installed on the front of the body, and a human body sensor for detecting a person in front is also installed on the front of the body.

[0013] The advantages and positive effects of the utility model are:

[0014] The utility model provides an interactive expression device for exhibition explanation robots with a reasonable structural design. Compared with the existing method of using a flat display screen for interactive expression display, the utility model adopts a projection area on the mask of the head and adopts a built-in projection expression component to project and display interactive expressions on the projection area. Since the principle of projection display is adopted, the projection area can be designed into a certain shape (such as an outward convex shape, etc.) instead of a flat shape as needed, and with the eye pattern and mouth pattern projected and displayed from the rear, a more vivid and three-dimensional interactive expression can be formed on the mask of the head. Since the projection expression component is configured with multiple projection membranes and a rotating drive component is used to drive the expression turntable to rotate so that one of the projection membranes is located on the light path, the interactive expression projected and displayed on the projection area can change in type.

[0015] Since an active lens driven by a shifting assembly to move forward and backward is arranged behind the fixed lens, the projection pattern can be enlarged and reduced by moving the active lens forward and backward when the projection forms an interactive expression, so that the interactive expression formed by the projection has certain dynamic changes. The interactive expression device for improving the experience of exhibitors of the utility model makes the explanation robot at the exhibition site have more vivid interactive expressions, gets rid of the drawback of the existing explanation robot that relies on a flat display screen to display expressions and has a dull image, and improves the experience of exhibitors.

[0023] See also Figure 1 and Figure 2 The interactive expression device of the exhibition explanation robot of the utility model comprises a mobile chassis 7, a body 4 is installed on the mobile chassis 7, and a head 1 is installed on the top of the body 4. Therefore, the interactive expression device of the exhibition explanation robot is based on the explanation robot configured at the exhibition site, and the mobile chassis 7 has rollers, so that the entire explanation robot can be displaced.

[0024] In this embodiment, a speaker hole is provided on the side of the body 4 and a speaker is installed inside the speaker hole, a display screen 6 is installed on the front of the body 4, and a human body sensor for detecting a person in front is also installed on the front of the body 4. The speaker is used to play the audio of the explanation, the display screen 6 is used to display the graphic information of the exhibition, and the human body sensor is used to detect whether there is a person in front.

[0025] The mobile chassis 7, the body with the display screen 6 and the human body sensor, and the head 1 are all structural features possessed by the existing explanation robots, and will not be described in detail in this embodiment.

[0026] A mask 3 with a projection area 2 is provided in front of the head 1, and three projection expression components 5 arranged in an inverted triangle are installed inside the head 1 and behind the projection area 2. The upper two projection expression components 5 project eye patterns on the projection area 2, and the lower projection expression component 5 projects a mouth pattern on the projection area 2. Therefore, the interactive expression device in the utility model adopts the projection principle, and forms interactive expressions by using three projection expression components 5 to project eye patterns and mouth patterns on the projection area 2 on the mask 3.

[0027] In this embodiment, three projection areas 2 are provided on the mask 3, arranged in an inverted triangle, the two upper projection areas 2 are used to project eye patterns, and the lower projection area 2 is used to project mouth patterns. Specifically, the portion of the mask 3 where no projection area 2 is provided is made of an opaque material, the projection area 2 is a transmissive projection screen (selected as an existing embossed plastic screen), a window is opened on the mask 3, the transmissive projection screen is cut into a specific shape and pressed into shape (such as an outward convex shape), and then installed on the window on the mask 3.

[0028] See also Figure 3 and Figure 4 , we can see that:

[0029] The projection expression assembly 5 includes a frame, a light source 5-4 is installed at the rear of the frame, a fixed lens 5-10 is installed at the front, and a movable lens 5-8 and a shift assembly driving the movable lens 5-8 to move forward and backward are arranged behind the fixed lens 5-10. An expression turntable 5-12 and a rotation drive assembly driving the expression turntable 5-12 to rotate are arranged in front of the light source 5-4. The expression turntable 5-12 has a plurality of projection films printed with different patterns, and the rotation drive assembly drives the expression turntable 5-12 to rotate so that one of the projection films is located on the light path.

[0030] Specifically, the projection films on the expression turntables 5-12 of the two projection-type expression components 5 located at the top are printed with different eye patterns, and the projection films on the expression turntables 5-12 of the projection-type expression component 5 located at the bottom are printed with different mouth patterns. When the rotary drive component drives the expression turntable 5-12 to rotate, different projection films are shifted to the light path, so that the projection pattern generated on the projection area 2 changes, and the interactive expression changes accordingly. When the movable lens 5-8 moves back and forth under the driving action of the shifting component, the distance between the fixed lens 5-10 and the movable lens 5-8 changes, and accordingly, the size of the projection pattern on the projection area 2 changes, so that the interactive expression formed by the projection has a certain dynamic effect.

[0031] In this embodiment, the frame of the projection expression component 5 includes two opposite side panels 5-1, a rear end panel 5-2 is installed between the rear ends of the two side panels 5-1, and a front end panel 5-9 is installed between the front ends, a light source 5-4 is installed on the rear end panel 5-2, a fixed lens 5-10 is installed on the front end panel 5-9, a rear partition panel 5-6 and a front partition panel 5-7 are installed between the middle parts of the two side panels 5-1, and light-transmitting windows are provided on the rear partition panel 5-6 and the front partition panel 5-7.

[0032] The light source 5-4 is an LED lamp bead, and the light generated passes forward through the light-transmitting window on the rear partition 5-6, then through the projection film, then through the light-transmitting window on the front partition 5-7, then through the movable lens 5-8, and then through the fixed lens 5-10. In this embodiment, a light source lens 5-5 is also installed by a bracket behind the rear partition 5-6 and in front of the light source 5-4. The function of setting the light source lens 5-5 is to converge the light emitted by the light source 5-4, from a divergent light source to a forward converging light beam, thereby improving the brightness of the projection.

[0033] In this embodiment, the rotary drive assembly includes a rotary motor 5-11 mounted on the front partition 5-7, and the center of the expression turntable 5-12 is fixedly connected to the output shaft of the rotary motor 5-11. The rotary motor 5-11 moves in a stepping manner, and the expression turntable 5-12 rotates a set angle once, and the previous projection film leaves the light path and the next projection film enters the light path.

[0034] In this embodiment, the shift assembly includes a moving base 5-14 installed on the front partition 5-7 and a shift motor 5-13 driving the moving base 5-14 to move forward and backward, and the movable lens 5-8 is fixedly installed on the moving base 5-14. Specifically, a guide column is installed on the front partition 5-7, a guide hole is provided on the moving base 5-14 and the guide column is located in the guide hole, a lead screw is installed on the output shaft of the shift motor 5-13, the moving base 5-14 is fixedly connected to the nut provided on the lead screw, and the shift motor 5-13 drives the lead screw to rotate forward or reverse, and the moving base 5-14 moves forward or backward accordingly.

[0035] A controller 5-3 is also installed on the rear end plate 5-2. The light source 5-4, the rotating motor 5-11 and the shifting motor 5-13 are connected to the controller 5-3. The controller 5-3 is connected to the control host of the explanation robot. Therefore, each projection expression component 5 receives instructions from the control host of the explanation robot through cables.

[0036] In this embodiment, the projection expression assembly 5 also includes a shell with a window on the front, the frame and auxiliary components of the projection expression assembly 5 are encapsulated inside the shell, and the fixed lens 5-10 is exposed from the window on the front of the shell.

[0037] How to run:

[0038] The explanation robot uses the method of outputting audio and displaying pictures and texts on the display screen 6 to give on-site explanations at the exhibition. When an exhibitor moves in front of the explanation robot or passes in front of the explanation robot, the human body sensor detects that a person is approaching and sends a signal to the control host of the explanation robot; the control host of the explanation robot sends instructions to each projection expression component 5 of the head 1 to produce interactive expression changes; specifically, after the controller 5-3 receives the instructions sent by the control host, the rotating motors 5-11 of the three projection expression components 5 drive their respective expression turntables 5-12 to rotate a certain angle, move the current projection film out of the light path and move the next projection film into the light path, then the projected interactive expression changes, and at the same time the shift motor 5-13 drives the moving base 5-14 to drive the movable lens 5-8 to move back and forth forward and backward several times, then the projection pattern on the projection area 2 changes in size several times, so that the interactive expression has a certain dynamic effect.
