Description

Technical Field

[0001] This utility model relates to infrastructure construction, specifically to a hidden projection equipment driven by a combination of translation and lifting. Background Technology

[0002] Projectors are essential equipment in buildings such as conference rooms and banquet halls, and for ease of use and to reduce space occupation, they are usually installed on the roof. With market advancements, the requirements for roof decoration and aesthetics are also increasing; therefore, concealing projectors in the roof and lowering them for use has become the mainstream approach.

[0003] In existing technologies, concealed projectors typically fix decorative panels to the bottom of the projector, which move during raising and lowering, and then return to their original position to form a complete roof decoration. This structure requires pre-planning spacing between the movable decorative panel units and adjacent units, resulting in poor aesthetics and reduced dust protection for the entire roof. Furthermore, the projector's raising, lowering, and resetting processes are prone to errors, often causing the movable decorative panel units to not fully reposition or extend beyond the decorative surface, leading to a poor decorative effect. Especially when the decorative panels are entirely composed of illuminated light panels, the weight and the aforementioned resetting issues often prevent achieving a cohesive and aesthetically pleasing finish.

[0004] Therefore, it is necessary to improve the existing roof-mounted concealed projection equipment so that the movable decorative panel units (including movable light panels) can be perfectly and seamlessly reset after the projection equipment is raised, lowered, used, or reset, thereby ensuring the integrity and aesthetics of the roof decorative layer without increasing costs excessively. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a hidden projection device driven by a combination of translation and lifting. After the projection device is lifted or reset, it ensures that the movable decorative panel unit (including the movable light panel) on the roof can be perfectly and seamlessly reset, thereby ensuring the integrity and decorativeness of the roof decorative layer without increasing costs excessively.

[0006] This utility model discloses a hidden projection device with a composite drive for translation and lifting, including a projector, a projector driving device, and a main driving device for driving the projector driving device to move horizontally and move the projector to a set position; at the set position, the projector driving device drives the projector to extend or hide; when the projector driving device is driven to move horizontally, it also drives the obstruction of the projector to move away.

[0007] Furthermore, the concealed projection equipment also includes a track, the projector driving device is mounted on the track and can be driven to move by the main driving device, and the projector is mounted below the projector driving device and can be driven to rise and fall.

[0008] Furthermore, there are two tracks, and the projector driving device is movably mounted on the tracks via a set of wheels. The set of wheels includes several roller shafts fixed to both sides of the projector driving device and several rollers that are rolled on the roller shafts. The rollers are rolled and engaged on the tracks.

[0009] Furthermore, roller bearing seats are respectively provided on both sides of the projector driving device, the inner end of the roller shaft is fixed to the roller bearing seat, and the upper part of the roller shaft is provided with reinforcing ribs that fix the roller shaft and the roller bearing seat.

[0010] Furthermore, the main drive device is fixed to the track by a main drive device mounting base. The main drive device mounting base includes two L-shaped mounting plates that are respectively fixed to both sides of the main drive device. The wing plates of the L-shaped mounting plates are fixed to the main drive device, and the web plates of the two L-shaped mounting plates extend to both sides and are fixed to the corresponding tracks. Reinforcing ribs are fixed between the wing plates and web plates of the L-shaped mounting plates.

[0011] Furthermore, a seat beam is fixedly provided between the two tracks, and the seat beam is provided with a certain pulley on the projector drive device; a steel cable is fixedly connected to the rear of the projector drive device and passes around its fixed pulley to output the power to remove the obstruction.

[0012] Beneficial Effects: This utility model's concealed projection equipment, driven by a combination of translation and lifting, uses a projector to move the device horizontally and move the projector to a set position. At this set position, the projector can be used and retracted for concealment. It is suitable for structures requiring projector concealment, such as roofs, and can utilize the spatial difference of horizontal movement to simultaneously move obstructions away. It can be applied to roofs in cinemas, conference halls, etc. For example, when applied to a roof, the movable lamp panel (including decorative panels) moves upward, leaving an opening for the projector to extend downward without interference. After resetting, the projector moves away, and the movable lamp panel resetting ensures that the movable decorative panel unit (including the movable lamp panel) can perfectly and seamlessly reset, thus maintaining the integrity and aesthetics of the roof decoration layer without incurring excessive costs. This utility model satisfies both the functional use of the projection equipment and the overall decorative effect, and has good technical results for high-requirement decorative space detail processing.

[0013] Figure 1 This is a schematic diagram of the structure of this utility model used in roofs;

[0014] Figure 2 This is a plan view of the present invention used on a roof;

[0015] Figure 3 for Figure 1 Enlarged view of point A. Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0017] Combination Figures 1-3 As shown, the hidden projection equipment driven by a combination of translation and lifting includes a projector 3, a projector driving device 4, and a main driving device 5 for driving the projector driving device to move horizontally and moving the projector to a set position; at the set position, the projector driving device 4 drives the projector 3 to move up and down, realizing the use and retraction of the projector; when the projector driving device is driven to move horizontally, it also drives the obstruction of the projector to move away.

[0018] The following are specific ways in which this utility model is applied to a roof, and the utility model will be described in detail through these methods:

[0019] The roof includes a floor slab 1 and a decorative layer composed of light panels. A roof interlayer B is formed between the decorative layer and the floor slab 1. A hidden projection device is provided in the roof interlayer B.

[0020] The decorative layer is provided with a movable lamp panel 2 at the set position. The movable lamp panel 2 is moved upward by the projector driving device 4 while the main driving device 5 drives the projector 3 to move horizontally (it may be a translational movement in different situations, such as cinema projection). Since the projector driving device 4 is driven to move horizontally, the conversion of horizontal movement into the up and down movement of the movable lamp panel requires a specific mechanical transmission system, such as using a belt drive to change the transmission direction and then using a small winch, or a pulley system, etc., which will not be elaborated here.

[0021] In this invention, the horizontal movement distance of the projector drive device 4 needs to be designed to ensure that the movable lamp panel 2 moves upward a sufficient distance so that the projector drive device 4 and the projector 3 can be translated to the set position. This can be calculated from the perspective of mechanical transmission, and will not be elaborated here. In this structure, when the projector appears, since the movable lamp panel moves upward, it can directly overlap with the adjacent lamp panel during reset, without the need for reset calibration, thus ensuring the overall integrity of the decoration. At the same time, since it moves upward, it is possible to install decorative strips between other lamp panels in the gap between the movable lamp panel and the adjacent lamp panel, so that the overall decoration is more perfect after reset.

[0022] In this invention, the projector driving device 4 and the main driving device 5 can be any existing device capable of linear telescopic drive, including a nut screw structure driven by a hollow motor, a hydraulic structure, etc. Preferably, a drive motor with a longer driving distance and lighter weight is used. As shown in the figure, the main driving device 5 is a drive motor that drives the projector driving device 4 to move horizontally through the telescopic mechanism 9. The projector driving device 4 is also a drive motor that drives the projector to rise and fall through the telescopic mechanism 8. Further details will not be provided here.

[0023] In this utility model, although a lamp panel is used as a component of the decorative layer, a general decorative panel can be used instead, which will not be described in detail here; the structure of the lamp panel belongs to the dot-hole decorative lamp panel used in general conference halls and banquet halls, and the specific structure will not be described in detail here.

[0024] In this embodiment, the concealed projection equipment also includes a track 6 laid in the roof interlayer. The projector driving device 4 is mounted on the track 6 and can be driven to move by the main driving device. The projector 3 is mounted below the projector driving device and can be driven to rise and fall. There are various ways to cooperate between the projector driving device 4 and the track. In practice, rails, straddle-type, etc. can be used. It can be a rolling cooperation or a sliding cooperation, which will not be described in detail here.

[0025] In this embodiment, when the projector driving device 4 is driven to move along the track 6, it simultaneously drives the movable lamp disk to move upward through the pulley assembly 7; the pulley assembly has strong adaptability and smooth transmission, and is low in cost.

[0026] In this embodiment, there are two tracks 6. The projector driving device 4 is movably mounted on the two tracks 6 via a set of wheels. The set of wheels includes several roller shafts 402 fixed to both sides of the projector driving device and several rollers 401 that are rolled on the roller shafts 402. The rollers 401 are rolled in cooperation with the track 6. As shown in the figure, there are 5 roller shafts 402 on each side of the projector driving device 4. Each roller shaft has a roller. The rollers and the track roll in cooperation to form a structure in which the projector driving device 4 can be driven to move. The design of multiple rollers makes the projector driving device 4 have strong support stability and smoother operation.

[0027] In this embodiment, the track 6 is fixedly suspended from the floor slab 1, and the distance between the two tracks is greater than the dimension of the movable lamp panel 2 in this direction (the direction of the distance between the tracks). As shown in the figure, the track is fixed to the floor slab by several suspension rods 10. The upper end of the suspension rod 10 is generally fixed to the floor slab 1 using an expansion bolt structure, and the lower end is fixed to the track by clamping the track with upper and lower nuts. The upper and lower nuts clamping the track is an existing mechanical connection structure, which will not be described in detail here. To ensure the fixing strength, a support structure can also be set on the suspension rod. For example, one end of the support rod is fixed to the suspension rod, and the other end is fixed to the floor slab to form a triangular support structure. It can be determined according to the needs during actual construction. At the same time, for the section of the track used for the projector driving device 4 to move, a fixed connection can be achieved by welding outwardly extending lugs 100. Other sections can be directly fixed to the track, which will not be described in detail here.

[0028] In this embodiment, the movable light panel 2 is fixedly provided with flanges 201 around it, and can be freely mounted on adjacent fixed light panels through the flanges 201. This structure can ensure that it can be accurately reset, ensure the integrity of the decoration, and does not interfere with the decorative strips between the light panels. The pulley assembly 7 lifts the movable light panel 2 through the flanges 201, realizing upward lifting and reset at the outermost edge, which helps to maintain the stability of the light panel.

[0029] In this embodiment, the pulley assembly includes two sets of pulleys arranged side by side. Each pulley set includes a first fixed pulley 701, a second fixed pulley 702, a third fixed pulley 703, and a fourth fixed pulley 704. The first fixed pulley 701 is located behind the projector driving device 4, meaning behind it is in the opposite direction to the set position (the position projected by the projector). The second fixed pulley 702, the third fixed pulley 703, and the fourth fixed pulley 704 are located on the floor slab. One end of a main steel cable 705 is fixed to the projector driving device 4, and the other end horizontally passes behind the first fixed pulley 701, then upwards past the second fixed pulley 702, and then passes through the third fixed pulley 703 and the fourth fixed pulley 704 respectively via a first branch cable 706 and a second branch cable 707. The first branch cable 706 and the second branch cable 707 are respectively connected downwards to two opposite sides of the movable lamp panel. The first fixed pulley is... The placement of the projector drive device 4 behind it can be done using existing mechanical equipment layouts, which will not be elaborated here. Meanwhile, the structure of the second fixed pulley 702, the third fixed pulley 703, and the fourth fixed pulley 704 installed on the floor slab is also a typical mechanical connection structure, such as expansion bolts, which will not be elaborated here. Furthermore, the pulley structure is also a typical mechanical transmission structure, which will not be elaborated here. The main steel cable 705 is generally a soft steel cable, and it is fixedly connected to the first branch cable 706 and the second branch cable 707 in front of the third pulley to form a linkage structure. The specific connection method can be bundling or separation from the main steel cable, which will not be elaborated here. As shown in the figure, the first branch cable 706 and the second branch cable 707 of the two pulley groups are respectively connected downwards to four connection points 2011 on the flanges of the two opposite sides of the movable lamp panel 2 (these connection points are fixed with lifting lugs), forming a four-point connection to ensure the stability of rising or resetting.

[0030] In this embodiment, roller bearing seats are respectively provided on both sides of the projector driving device 4. The roller bearing seat is an integral steel plate with a set thickness. The shape of the steel plate is adapted to the shape of the projector driving device 4 (it can be an arc-shaped steel plate or a flat plate). It can be set by welding or bolting. The inner end of the roller shaft 402 is fixed to the roller bearing seat 403. The fixing method is generally to insert it into the corresponding hole opened in the roller bearing seat 403 and form a weld. The upper part of the roller shaft 402 is provided with a reinforcing rib 4021 that is fixedly connected (generally welded) between the roller shaft 402 and the roller bearing seat, which can ensure the ability of the roller shaft 402 to withstand downward loads.

[0031] The main drive device 5 is fixed to the track 6 by a main drive device mounting base. The main drive device mounting base includes two L-shaped mounting plates 501 that are respectively fixed to both sides of the main drive device. The wing plates of the L-shaped mounting plates 501 are fixed to the main drive device (generally by welding or bolting, and the shape of the wing plates is adapted to the main drive device, and can be an arc plate or a flat plate). The web plates of the two L-shaped mounting plates 501 extend to both sides and are fixed to the corresponding track 6. A reinforcing rib 5011 is fixed between the wing plates and web plates of the L-shaped mounting plates to provide stable installation strength.

[0032] In this embodiment, a seat beam is fixedly installed between the two tracks 6 and behind the projector driving device 4. A fixed pulley is mounted on the seat beam. A steel cable is fixedly connected to the rear of the projector driving device and passes around the fixed pulley to provide power to remove the obstruction. As shown in the figure, when this structure is applied to a roof, the steel cable is the total steel cable 705, the fixed pulley is the first fixed pulley 701, and the seat beam is the fixed pulley seat beam 708 shown in the figure. The first fixed pulley is mounted on the fixed pulley seat beam 708. A traction seat 709 is fixedly installed on the rear side of the projector driving device 4. The traction seat 709 extends to both sides and is fixedly connected near its ends. The connecting lugs of the main steel cable 705; the setting of the traction seat 709 can ensure a wide distance between the two pulley groups, a wide distance between the connection points of the movable lamp panel, and stability during lifting and resetting; the traction seat 709 can be a separate type fixed to the projector drive device 4, or it can be an integral structure, which will not be elaborated here; as shown in the figure, the traction seat 709 is a plate structure with reinforcing ribs to ensure sufficient traction strength; of course, in order to ensure a connection point with a certain width, the purpose can also be achieved without the traction seat, for example, by using an inclined pulley setting, which can still achieve the purpose, which will not be elaborated here.

[0033] In this embodiment, a guide plate 11 is provided around the movable lamp panel 2 to guide the movable lamp panel to reset. The guide plate 11 is tilted upward and outward at a set angle, and its lower end is as close as possible to the flange 201 of the movable lamp panel 2. The guide plate is set to avoid the channel through which the projector driving device 4 moves into the set position. As shown in the figure, multiple guide plates form a structure similar to an inverted trapezoid with a vertical cross section, which can play an auxiliary guiding role during reset. It will not be described in detail here. The guide plate can be directly welded to the frame of the lamp panel.

[0034] The above embodiments are only the structures of this utility model used on roofs. Of course, this utility model can also be applied to other structures that require hiding the lift-up projector, which will not be described in detail here.
