Description

TECHNICAL FIELD

[0001] The present invention relates to a frame structure; in particular, to a frame structure for a dome screen. BACKGROUND

[0002] The existing virtual reality movie system is to project images on a cloth dome screen or to play images on a LED dome screen structure, so as to provide virtual reality visual experience for viewers. The dome screen is constructed by arranging part of the cloth screen or part of the LED display on the frame of the dome screen to form a hemispherical display area.

[0003] When the above-mentioned dome screen is repaired, for example, when the south pole area at the bottom side of the LED dome screen is repaired, there is no position for the repairer to stand, so the repairer needs to repair by lying on the circuit board of the LED, which makes the repair process more difficult and has the risk of damaging the LED. Therefore, it is necessary to improve the frame structure after the dome screen is installed, so that the repairer can access the repair area and has a certain operation space, so as to solve the difficulties encountered by the repairer during maintenance and repair. SUMMARY

[0004] Therefore, the purpose of the present invention is to provide a frame structure, which includes a fixed frame and a movable frame that can move relative to the fixed frame. The repair area that appears after the movable frame and the fixed frame are pulled apart serves as the operation space for the repairer, achieving the effect of facilitating the repair of the dome screen structure installed on the fixed frame or the movable frame.

[0005] In order to achieve the above-mentioned purpose, the present invention provides a dome screen frame with a movable component, which is used to set up multiple display screens or projection screens to form a dome screen, and includes a fixed frame fixed on a base surface and a movable frame arranged on the base surface, wherein the movable frame can move back and forth relative to the fixed frame along a predetermined track on the base surface between a combined position and a detached position.

[0006] When the present invention is used, parts of the dome screen are arranged on the fixed frame and the movable frame respectively. When the dome screen around the movable frame needs to be repaired, the movable frame is moved outward relative to the fixed frame along the predetermined track, so that a space as a working area is generated between the movable frame and the fixed frame.

[0007] When the dome screen installed in the present invention is maintained or repaired, the repairer can access the dome screen that needs to be repaired from the working area, without the need to repair by lying on the frame, so as to achieve the effect of not easily damaging the LED circuit board of the dome screen. Further, when the movable frame of the present invention is divided into several frame components, the parts of the dome screen corresponding to each frame component can be attached well in the factory area. When each frame component is installed together with the dome screen on the base surface at the site, the installed dome screen has better flatness. BRIEF DESCRIPTION OF DRAWINGS

[0040] In order to make the present application clearer, preferred embodiments will be described in detail as follows with reference to the drawings.

[0041] Referring to Figures 1 to 7 Fig. 1, a ball screen frame 100 of a movable assembly according to a first preferred embodiment of the present application includes a base surface A, a fixed frame 10 combined with the base surface A, and a movable frame 20 arranged on the base surface A. In the preferred embodiment, the fixed frame 10 is a frame body with a semispherical inner surface. The fixed frame 10 has a south pole region at the bottom side thereof, and the movable frame 20 is arranged in an accommodating space B of the south pole region.

[0042] In the preferred embodiment, the movable frame 20 is a semicircular frame body, and can reciprocate along a predetermined track on the base surface A relative to the fixed frame 10 between a combined position and a detached position.

[0043] The fixed frame 10 and the movable frame 20 are respectively used to arrange parts of a ball screen. When the movable frame 20 is located at the combined position, the parts of the ball screen arranged by the movable frame 20 are combined with the parts of the ball screen arranged in the fixed frame 10 to form a state of the ball screen.

[0044] The fixed frame 10 of the first preferred embodiment is a frame with a semispherical inner surface, and the moving frame 20 is a semicircular frame. In other embodiments, the fixed frame 10 and the moving frame 20 can be designed as frames with partial spherical inner and outer surfaces, and the partial spherical dome is divided into two parts, one part is arranged on the fixed frame 10 and the other part is arranged on the moving frame 20. When the moving frame 20 is in the combined position, the two parts can be combined to form the whole spherical dome.

[0045] When the spherical dome is used, the LED display of the spherical dome is arranged on the fixed frame 10 and the moving frame 20. When the spherical dome installed on the present application needs to be maintained or repaired, the moving frame 20 is moved outward along the predetermined track relative to the fixed frame 10, so that a space as a working area is formed between the moving frame 20 and the fixed frame 10. At this time, the maintenance personnel can access the LED circuit board that needs to be repaired from the working area, and the working area also provides the operation space for the maintenance personnel during maintenance. In addition to facilitating the maintenance personnel to perform maintenance work, it can also avoid damaging the LED circuit board during the maintenance process.

[0046] Further description of the detailed structure of the first preferred embodiment. Please refer to Figure 2 to Figure 7 The fixed frame 10 has a fixed base frame 12 and a fixed dome frame 14. The fixed frame 10 is fixed to the base surface A. The fixed dome frame 14 is connected to the inner side of the fixed base frame 12 and is supported by the fixed base frame 12. A bottom plate A1 is arranged on the base surface A corresponding to the position of the moving frame 20. The south pole part of the spherical dome is divided into six parts. The accommodation space B of the south pole area of the fixed frame 10 is divided into six areas. The moving frame 20 is modularly divided into six frame assemblies 22 corresponding to the six areas. The frame assemblies 22 are arranged on the bottom plate A1 and each have a base frame 221 and a dome frame 222. The dome frame 222 is combined above the base frame 221 and is supported by the base frame 221.

[0047] At least one slide rail 24 is combined at the bottom of each frame assembly 22. In the preferred embodiment, two slide rails 24 are combined at the bottom of each frame assembly 22 in a left-right spaced manner. The slide rails 24 are tracks extending in the front-back direction and each include a fixed rail 241 and a movable rail 242 slidably arranged on the fixed rail 241. The fixed rail 241 is combined with the bottom plate A1, and the movable rail 242 is combined with the frame assembly 22. The slide rails 24 are combined between the frame assemblies 22 and the base surface A, and the extension direction of the slide rails 24 is the same as the direction of the predetermined track. Therefore, the frame assemblies 22 can move linearly along the front-back direction relative to the fixed frame 10 within a certain movement range between the initial state and the extension limit of each slide rail 24 along the linear predetermined track.

[0048] To make the frame components 22 of the mobile frame 20 better supported and make the frame components 22 move more smoothly on the base surface A or the bottom plate A1, the positions of the two slide rails 24 at the bottom of each frame component 22 are set to be staggered forward and backward along the direction of the predetermined track, so that the two slide rails 24 can share more weight of the frame components 22 in a wider setting range to achieve a better supporting effect of the frame components 22. In combination with the two slide rails 24 combined at the bottom of the frame component 22, at least one pulley 26 is combined at the bottom of the frame component 22 where the two slide rails 24 are not arranged, please refer to the figure shown in Figure 6 、 Figure 7 In the preferred embodiment, two pulleys 26 are combined at the left and right positions of the front side of the bottom of the frame component 22, so that each frame component 22 is supported by the two slide rails 24 at the back side and the two pulleys 26 at the front side.

[0049] Please refer to the figure shown in Figures 6 to 9 When maintaining, one frame component 22 or more than two frame components 22 of the mobile frame 20 can be pulled out along the predetermined track to make the space of the working area C between the frame component 22 and the fixed frame 10 or between two adjacent frame components 22, so that the maintenance personnel can easily enter the cleaning or maintenance area of the LED circuit board of the dome screen. In the preferred embodiment, the slide rails 24 are set as damping slide rails, when resetting the frame component 22, as long as the frame component 22 is pushed back to move to the area close to the combined position, the frame component 22 can be automatically moved to the combined position by the retraction function of the slide rails 24. The pulleys 26 are pulleys with brakes, the frame component 22 can be positioned at the combined position by the brake function of the pulleys 26, after the frame component 22 is moved outward along the predetermined track relative to the fixed frame 10, the position of the frame component 22 can be fixed at the detached position by the brake function of the pulleys 26, which ensures that the frame component 22 will not return to the original position when the maintenance personnel operates in the maintenance area, and improves the safety of the maintenance operation.

[0050] In addition to the first preferred embodiment described above, the mobile frame 20 can be set as a frame component 22 itself, or set as more than two frame components 22. In addition, the predetermined track of the movement of the frame components 22 can be a straight track, please refer to the second preferred embodiment of the present application shown in Figure 10 The frame components 22 of the mobile frame 20 can be set to rotate reciprocatingly along a circular arc-shaped predetermined track on the base surface A relative to the fixed frame 10.

[0051] In addition to using the brake function of the pulley 26 to fix the position of the frame assembly 22 in the combined position or the disengaged position, please refer to Figure 11 In other preferred embodiments, as shown, a first magnet 28 can also be combined with the frame assembly 22, and a second magnet 281 can be combined with the base surface A in correspondence with the first magnet 28 being in the combined position or the disengaged position. By means of the first magnet 28 being magnetically attracted to one of the second magnets 281 or the other second magnet 281 before and after the frame assembly 22 is moved, the frame assembly 22 can be positioned in the combined position or the disengaged position, respectively.

[0052] Alternatively, please refer to Figure 12 In another preferred embodiment, as shown, a stop ramp 29 can also be combined with the base surface A in correspondence with the pulley 26 being in the combined position or the disengaged position. By means of the pulley 26 being withdrawn into one of the stop ramps 29 when the frame assembly 22 is in the combined position, the stop ramp 29 blocks the pulley 26 in front to fix the position of the frame assembly 22; or by means of the pulley 26 passing over the other stop ramp 29 when the frame assembly 22 is moved to the disengaged position, the frame assembly 22 is positioned in the disengaged position. The above configuration enables the frame assembly 22 to be positioned in the combined position or the disengaged position, respectively.

[0053] The above description is only the preferred and feasible embodiments of the present application. Any equivalent changes made in accordance with the description and the scope of the patent application should be included in the patent scope of the present application.
