Description

Technical Field

[0001] The present invention relates to the technical field of projectors, and in particular to an adjustment device for a holographic projector. Background Art

[0002] In the field of modern multimedia display and demonstration, holographic projectors can create realistic three-dimensional scenes with their unique imaging effects. They are widely used in many scenarios such as commercial displays, education and training, and stage performances. With the popularization of holographic projection technology and the expansion of application scenarios, higher requirements are placed on the installation and use convenience, equipment stability, and heat dissipation performance of holographic projectors.

[0003] However, during the operation of the projector, especially when the projector is installed at a high position close to heat accumulation areas such as the ceiling, the heat generated inside the projector is difficult to dissipate effectively. The traditional heat dissipation fin structure has a fixed spacing and cannot flexibly adjust the heat dissipation area according to the environment and height changes of the projector, resulting in low heat dissipation efficiency, affecting the normal operation of the internal components of the projector, and thus shortening the service life of the projector.

[0004] In view of this, research and improvement are conducted on the existing problems, and an adjustment device for a holographic projector is provided, aiming to solve the problems and improve the practical value through this technology. Summary of the invention

The present invention realizes automatic adjustment of the suspension height of the projector body through a driving motor, a screw rod, etc., without the need for manual disassembly of the lifting bracket, thereby improving the convenience of use. At the same time, when adjusting the height, the screw rod drives the gear to expand the spacing between the heat dissipation fins, thereby increasing the heat dissipation area. Combining the height and heat dissipation adjustment, the stable operation of the projector is guaranteed. In addition, when the heat dissipation fins are actuated, the piston is driven to squeeze the gas, so that the lubricating oil in the oil storage tank lubricates the internal threaded cylinder, thereby reducing component wear, and coordinating with heat dissipation to achieve automatic lubrication and reduce maintenance costs.

[0009] Preferably, the mounting plate is fixed to the roof by bolts.

[0010] Preferably, the cross-sectional shape of the guide rail is T-shaped, and a T-shaped sliding block matched with the guide rail is provided at the bottom of the movable plate.

[0014] Preferably, the outer wall of the piston is sleeved with a rubber ring, and the rubber ring is slidably connected to the inner wall of the sleeve.

[0015] Preferably: one-way air intake valves are installed at both ends of the sleeve, and a one-way air exhaust valve is installed at the connection between the sleeve and the air pipe.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention utilizes that when the screw rotates to adjust the height, the gear on the outer wall of the screw will also rotate synchronously. The rotation of the gear will drive the rack to make a linear motion along the guide rail, and the rack can drive the slide plate to slide on the inner bottom end of the shell through the push rod. The surface of the slide plate is provided with multiple groups of guide grooves. When the slide plate moves, the guide grooves will guide the round rod to move, thereby making multiple groups of heat dissipation fins move along the slide rod with equal intervals. When the projector body is raised to approach the heat accumulation area of ​​the ceiling, the spacing between the multiple groups of heat dissipation fins is expanded, thereby increasing the heat dissipation area, improving the heat dissipation effect, and effectively ensuring the stable operation of the projector body. The device combines height adjustment with heat dissipation area adjustment, and synchronously adjusts the opening and closing states of the heat dissipation fins during the height adjustment process to adapt to the temperature difference at different heights, so that the projector body can maintain good heat dissipation conditions at different installation heights, significantly improving the heat dissipation efficiency, ensuring the stable operation of internal components, and extending the service life of the projector.

[0017] 2. The present invention starts the driving motor in the box to rotate forward, and the output end of the driving motor drives the screw to rotate through the coupling. When the screw rotates, the internal threaded barrel cannot rotate due to the limitation of the guide seat and the guide rod, and can only make linear motion along the axial direction of the screw. At this time, the screw rotates and moves upward in the internal threaded barrel, and the projector body is connected to the mounting plate, so the movement of the screw can synchronously drive the projector body to move upward, thereby realizing the adjustment of the hanging height of the projector body. This adjustment method does not require manual disassembly and lifting of the bracket structure, realizes automatic operation, and greatly improves the convenience of use of the device.

[0018] 3. The present invention utilizes that during the operation of the heat dissipation mechanism, the heat dissipation fins will open and close as the height of the projector body is adjusted. When the heat dissipation fins move, the heat dissipation fins synchronously drive the ring to move through the connecting rod, and the ring moves along the outer wall of the sleeve. The piston is magnetically connected to the magnet, so the movement of the ring can drive the piston to slide inside the sleeve. During the sliding process of the piston in the sleeve, the gas on one side of the sleeve will be compressed into the oil storage tank through the gas pipe. As the gas is continuously compressed and enters, the pressure inside the oil storage tank gradually increases. Under the action of the increased pressure, the lubricating oil in the oil storage tank is squeezed, and the lubricating oil enters the nozzle through the oil pipe. Finally, the lubricating oil drips from the nozzle evenly onto the inner wall of the internal threaded barrel. When the screw rotates and moves up and down in the internal threaded barrel, good lubrication can effectively reduce the friction between the components of the adjusting mechanism, thereby reducing the degree of wear between the components, and further extending the service life of the adjusting mechanism. By working in coordination with the heat dissipation mechanism, automatic lubrication of the adjusting device is achieved, which not only improves the operating efficiency of the equipment, but also reduces the labor maintenance cost, thereby ensuring the long-term and stable operation of the entire device.

[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] The present invention provides an adjustment device for a holographic projector, comprising a projector body 1, a mounting plate 2 is arranged on the top of the projector body 1, a box 3 is fixedly installed on the top of the projector body 1, a driving motor 4 is installed inside the box 3, a screw 5 is installed on the output end of the driving motor 4 through a coupling, an internal threaded tube 6 is fixedly connected to the bottom end of the mounting plate 2, a guide seat 7 is fixedly sleeved on the outer wall of the internal threaded tube 6, two groups of guide rods 8 are slidably penetrated on the surface of the guide seat 7, a heat dissipation mechanism 9 for adjusting the heat dissipation area is arranged on the top of the projector body 1, and a lubrication mechanism 10 for lubricating the adjustment component is arranged on one side of the top of the projector body 1; See also Figures 1 to 5As shown, the heat dissipation mechanism 9 includes a heat conducting plate 901 installed on the top of the projector body 1, the top of the heat conducting plate 901 is fixedly connected with a shell 902, two groups of symmetrically arranged slide bars 903 are fixedly installed on the inner wall of the shell 902, multiple groups of heat dissipation fins 904 are slidably arranged on the outer wall of the slide bar 903, a slide plate 905 is slidably arranged on the inner bottom end of the shell 902, multiple groups of guide grooves 906 are arranged on the surface of the slide plate 905, a round rod 907 is fixedly connected to the bottom of the heat dissipation fin 904, a gear 908 is fixedly sleeved on the outer wall of the bottom end of the lead screw 5, a guide rail 909 is installed on the top of the projector body 1, a movable plate 910 is slidably arranged inside the guide rail 909, one end of the movable plate 910 is fixedly connected with a rack 911 meshing with the gear 908, and one side of the rack 911 is fixedly connected to one side of the slide plate 905 by a push rod 912; It should be noted that when the height of the projector body 1 needs to be adjusted, first start the drive motor 4 in the box 3 to rotate forward. The output end of the drive motor 4 drives the screw 5 to rotate through the coupling. Since there is a threaded connection between the screw 5 and the internal threaded tube 6, when the screw 5 rotates, the internal threaded tube 6 cannot rotate due to the restrictions of the guide seat 7 and the guide rod 8, and can only make linear motion along the axial direction of the screw 5. At this time, the screw 5 rotates and moves upward in the internal threaded tube 6. Since the mounting plate 2 is fixedly connected to the internal threaded tube 6, and the projector body 1 is connected to the mounting plate 2, the movement of the screw 5 can synchronously drive the projector body 1 to move upward, thereby realizing the adjustment of the hanging height of the projector body 1. This adjustment method does not require manual disassembly and lifting of the bracket structure, realizes automated operation, and greatly improves the convenience of use of the device; In addition, when the screw rod 5 rotates to adjust the height, the gear 908 fixedly mounted on the outer wall at the bottom end of the screw rod 5 will also rotate synchronously. Because the gear 908 and the rack 911 are in a meshing state, the rotation of the gear 908 will drive the rack 911 to make a linear motion along the guide rail 909. One end of the rack 911 is connected to the slide plate 905 through the push rod 912, so the linear motion of the rack 911 can drive the slide plate 905 to slide at the bottom end of the shell 902 through the push rod 912. The surface of the slide plate 905 is provided with multiple groups of guide grooves 906, and the bottom of the heat dissipation fin 904 is fixedly connected to a round rod 907, and the round rod 907 slides in the guide groove 906. When the slide plate 905 moves, the guide groove 906 will guide The guide rod 907 moves, thereby causing the multiple groups of cooling fins 904 to move at equal intervals along the sliding rod 903. In this way, when the projector body 1 is raised to approach the heat accumulation area of ​​the ceiling, the spacing between the multiple groups of cooling fins 904 is expanded, thereby increasing the cooling area, improving the cooling effect, and effectively ensuring the stable operation of the projector body 1. The device combines height adjustment with cooling area adjustment, and synchronously adjusts the opening and closing states of the cooling fins 904 during the height adjustment process to adapt to the temperature difference at different heights, so that the projector body 1 can maintain good cooling conditions at different installation heights, significantly improving the cooling efficiency, ensuring the stable operation of internal components, and extending the service life of the projector.

[0023] See also Figures 6 to 8 As shown, the lubrication mechanism 10 includes an oil storage tank 1001 installed on the top of the projector body 1, a mounting seat 1002 is installed on the top of the projector body 1 near the shell 902, a sleeve 1003 is fixedly connected to the surface of the mounting seat 1002, a piston 1004 slides inside the sleeve 1003, a collar 1005 is sleeved on the outer wall of the sleeve 1003, a plurality of groups of magnets 1006 are arranged on the inner wall of the collar 1005, and the plurality of groups of magnets 1006 slide on the outer wall of the sleeve 1003, the heat dissipation fins 904 and the collar 1005 are fixedly connected by a connecting rod 1007, the oil storage tank 1001 and the sleeve 1003 are connected by an air pipe 1008, a mounting groove 1011 is provided on the outer wall of the internal threaded cylinder 6, a nozzle 1012 is installed inside the mounting groove 1011, and the oil storage tank 1001 and the nozzle 1012 are connected by an oil pipe 1013.

[0024] It should be noted that during the operation of the heat dissipation mechanism 9, the heat dissipation fins 904 will open and close as the height of the projector body 1 is adjusted. When the heat dissipation fins 904 move, the ring 1005 fixedly connected to it by the connecting rod 1007 will also be driven synchronously. The ring 1005 moves along the outer wall of the sleeve 1003. Since a plurality of groups of magnets 1006 are arranged on the inner wall of the ring 1005, the piston 1004 is magnetically connected to the magnet 1006. Therefore, the movement of the ring 1005 can drive the piston 1004 to slide inside the sleeve 1003. During the sliding process of the piston 1004 in the sleeve 1003, the gas on one side of the sleeve 1003 will be compressed into the oil storage tank 1001 through the gas pipe 1008. As the gas is continuously compressed and enters, the pressure inside the oil storage tank 1001 is increased. The strength gradually increases. Under the action of the increasing pressure, the lubricating oil in the oil storage tank 1001 is squeezed, and the lubricating oil enters the nozzle 1012 installed in the mounting groove 1011 on the outer wall of the internal threaded barrel 6 through the oil pipe 1013. Finally, the lubricating oil drips evenly from the nozzle 1012 to the inner wall of the internal threaded barrel 6. Since the screw rod 5 and the internal threaded barrel 6 are connected by threads, when the screw rod 5 rotates and moves up and down in the internal threaded barrel 6, good lubrication can effectively reduce the friction between the components of the adjusting mechanism, thereby reducing the degree of wear between the components, and then can extend the service life of the adjusting mechanism. By working in coordination with the heat dissipation mechanism 9, automatic lubrication of the adjusting device is realized, which not only improves the operating efficiency of the equipment, but also reduces the labor maintenance cost, thereby ensuring the long-term stable operation of the entire device.

[0025] See also Figures 4 to 5 As shown, multiple groups of heat sink fins 904 are arranged at equal intervals, and the round rod 907 slides inside the guide groove 906. The heat sink fins 904 arranged at equal intervals can ensure that the heat is evenly distributed between the heat sink fins 904 to avoid local heat accumulation. When the projector is running, the heat is transferred to the heat sink fins 904 through the heat conduction plate 901. The equally spaced layout allows the heat to be more evenly dissipated into the surrounding air, thereby improving the overall heat dissipation efficiency. The guide groove 906 provides a precise movement path for the round rod 907, ensuring that the heat sink fins 904 can slide smoothly along the preset trajectory during movement.

[0026] See also Figure 1 to Figure 2As shown, the outer wall of the screw rod 5 is threadedly connected to the inner wall of the internal threaded tube 6, and the bottom ends of the two groups of guide rods 8 are fixedly connected to the bottom end of the projector body 1. The two groups of guide rods 8 are symmetrically distributed about the central axis of the screw rod 5. The screw rod 5 is driven to rotate by the driving motor 4. The threaded cooperation between the screw rod 5 and the internal threaded tube 6 can convert the rotational motion into linear motion, so that the projector body 1 can achieve precise height adjustment to meet the projection requirements in different scenes. The guide rod 8 can accurately guide the lifting and lowering movement of the projector body 1, which can effectively prevent the projector body 1 from deflecting or rotating during the lifting process, and ensure that it moves smoothly along the predetermined trajectory.

[0027] See also Figure 1 As shown, the mounting plate 2 is fixed to the roof by bolts, which can provide stable and firm support for the entire projector adjustment device, ensuring that the device will not shake or shift during operation.

[0028] See also Figure 3 As shown, the cross-sectional shape of the guide rail 909 is T-shaped, and a T-shaped slider adapted to the guide rail 909 is provided at the bottom of the movable plate 910, which can effectively limit the movement direction of the movable plate 910 and ensure its smooth movement along the predetermined track of the guide rail 909.

[0029] See also Figure 4 As shown, the surface of the heat sink fin 904 is provided with a nano heat sink coating. The heat sink fin 904 is made of aluminum alloy. The nano heat sink coating can effectively improve the heat dissipation efficiency of the heat sink fin 904, accelerate heat dissipation, and enhance the heat dissipation performance of the entire heat sink mechanism 9.

[0030] See also Figure 6 As shown, the oil storage tank 1001 is made of a transparent material, and the outer wall of the oil storage tank 1001 is provided with scale lines, so that the user can visually observe the remaining amount of lubricating oil, and thus reasonably arrange the replenishment of lubricating oil.

[0031] See also Figure 7 As shown, the piston 1004 is made of ferritic stainless steel material, and the piston 1004 is magnetically connected to the magnet 1006. The ferritic stainless steel has good magnetic properties and can be magnetically connected to the magnet 1006, so that the piston 1004 can be driven by magnetic force.

[0032] See also Figure 7 As shown, a rubber ring is sleeved on the outer wall of the piston 1004, and the rubber ring is slidably connected to the inner wall of the sleeve 1003. The rubber ring can effectively prevent gas from leaking from the gap between the piston 1004 and the sleeve 1003 during the movement of the piston 1004, thereby improving the sealing performance.

[0033] See also Figure 7As shown, one-way air intake valves 1009 are installed at both ends of the sleeve 1003, and a one-way exhaust valve 1010 is installed at the connection between the sleeve 1003 and the air pipe 1008. During the movement of the piston 1004, the one-way air intake valve 1009 allows external gas to enter the sleeve 1003, while the one-way exhaust valve 1010 transports the compressed gas to the oil storage tank 1001 through the air pipe 1008, thereby pushing the lubricating oil into the nozzle 1012.

[0034] Working principle: When the height of the projector body 1 needs to be adjusted, first start the drive motor 4 in the box 3 to rotate forward. The output end of the drive motor 4 drives the screw 5 to rotate through the coupling. Since there is a threaded connection between the screw 5 and the internal threaded tube 6, when the screw 5 rotates, the internal threaded tube 6 cannot rotate due to the restrictions of the guide seat 7 and the guide rod 8, and can only make linear motion along the axial direction of the screw 5. At this time, the screw 5 rotates and moves upward in the internal threaded tube 6. Since the mounting plate 2 is fixedly connected to the internal threaded tube 6, and the projector body 1 is connected to the mounting plate 2, the movement of the screw 5 can synchronously drive the projector body 1 to move upward, thereby realizing the adjustment of the hanging height of the projector body 1. This adjustment method does not require manual disassembly and lifting of the bracket structure, realizes automatic operation, and greatly improves the convenience of use of the device; In addition, when the screw rod 5 rotates to adjust the height, the gear 908 fixedly mounted on the outer wall at the bottom end of the screw rod 5 will also rotate synchronously. Because the gear 908 and the rack 911 are in a meshing state, the rotation of the gear 908 will drive the rack 911 to make a linear motion along the guide rail 909. One end of the rack 911 is connected to the slide plate 905 through the push rod 912, so the linear motion of the rack 911 can drive the slide plate 905 to slide at the bottom end of the shell 902 through the push rod 912. The surface of the slide plate 905 is provided with multiple groups of guide grooves 906, and the bottom of the heat dissipation fin 904 is fixedly connected to a round rod 907, and the round rod 907 slides in the guide groove 906. When the slide plate 905 moves, the guide groove 906 will guide The guide rod 907 moves, thereby making the multiple groups of heat dissipation fins 904 move at equal intervals along the slide rod 903. In this way, when the projector body 1 is raised to approach the heat accumulation area of ​​the ceiling, the spacing between the multiple groups of heat dissipation fins 904 is expanded, thereby increasing the heat dissipation area, improving the heat dissipation effect, and effectively ensuring the stable operation of the projector body 1. The device combines height adjustment with heat dissipation area adjustment, and synchronously adjusts the opening and closing state of the heat dissipation fins 904 during the height adjustment process to adapt to the temperature difference at different heights, so that the projector body 1 can maintain good heat dissipation conditions at different installation heights, significantly improving the heat dissipation efficiency, ensuring the stable operation of internal components, and extending the service life of the projector; During the operation of the heat dissipation mechanism 9, the heat dissipation fins 904 will open and close as the height of the projector body 1 is adjusted. When the heat dissipation fins 904 move, the ring 1005 fixedly connected to it by the connecting rod 1007 will also be driven synchronously. The ring 1005 moves along the outer wall of the sleeve 1003. Since multiple groups of magnets 1006 are arranged on the inner wall of the ring 1005, the piston 1004 is magnetically connected to the magnet 1006, so the movement of the ring 1005 can drive the piston 1004 to slide inside the sleeve 1003. During the sliding process of the piston 1004 in the sleeve 1003, the gas on one side of the sleeve 1003 will be compressed into the oil storage tank 1001 through the gas pipe 1008. As the gas is continuously compressed and enters, the pressure inside the oil storage tank 1001 gradually increases. The lubricating oil in the oil storage tank 1001 is squeezed under the action of the increased pressure, and the lubricating oil enters the nozzle 1012 installed in the mounting groove 1011 on the outer wall of the internal threaded barrel 6 through the oil pipe 1013. Finally, the lubricating oil drips evenly from the nozzle 1012 to the inner wall of the internal threaded barrel 6. Since the screw rod 5 is connected to the internal threaded barrel 6 by threads, when the screw rod 5 rotates and moves up and down in the internal threaded barrel 6, good lubrication can effectively reduce the friction between the components of the adjusting mechanism, thereby reducing the degree of wear between the components, and thus extending the service life of the adjusting mechanism. By working in coordination with the heat dissipation mechanism 9, automatic lubrication of the adjusting device is realized, which not only improves the operating efficiency of the equipment, but also reduces the labor maintenance cost, thereby ensuring the long-term stable operation of the entire device.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
