Description

Technical Field

[0001] This utility model relates to the field of projector accessories technology, and in particular to a heat dissipation base for projectors. Background Technology

[0002] With the continuous development of technology, projectors have been widely used in offices, education, and home entertainment. However, projectors generate a lot of heat during operation. If this heat is not dissipated in time, it will not only affect the projector's performance and lifespan, but may also lead to equipment malfunctions or even safety issues. Currently, the main heat dissipation methods for projectors on the market are built-in fan cooling and external cooling devices. Built-in fan cooling has limited effectiveness and is easily limited by the internal space and structure of the projector. External cooling devices, on the other hand, suffer from problems such as large size, inconvenience in carrying, and unstable cooling performance. Therefore, a new type of projector cooling stand is needed to meet the heat dissipation needs of projectors in different usage scenarios.

[0003] Existing projector bases lack a precisely designed transmission structure to drive the cooling fan, potentially leading to unstable fan operation, excessive noise, and increased risk of malfunction. Furthermore, the inconveniently removable and maintainable filter may cause excessive dust accumulation, affecting heat dissipation and even damaging the projector. Therefore, we propose a projector cooling base to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a heat dissipation base for a projector to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A heat dissipation base for a projector includes: a projector body, a frame connected to the bottom of the projector body, a base body fixedly mounted on the outer side of the frame, a rotating rod rotatably mounted inside the projector body, two sets of bevel gears fixedly mounted on the outer side of the rotating rod, a support plate fixedly mounted inside the frame, two sets of rotating shafts rotatably mounted inside the support plate, bevel gears fixedly mounted on the top of each of the two sets of rotating shafts, a cooling fan fixedly mounted at one end of each of the two sets of rotating shafts, a filter screen movably abutting against the bottom of the frame, four sets of support legs fixedly mounted on the bottom of the base body, a micro motor fixedly mounted on one side of the projector body, two sets of insert rods movably inserted inside the filter screen, two sets of insert rods movably inserted inside the frame, springs sleeved on the outer side of the two sets of insert rods, a common connecting plate fixedly mounted on one side of the insert rods on the same side, and a pull ring fixedly mounted on one side of the two sets of connecting plates.

[0007] Preferably, a lifting platform is fixedly installed at the bottom of the four sets of support legs. Four sets of limiting rods are slidably installed inside the lifting platform. A base plate is fixedly installed at the bottom of the four sets of limiting rods. Two sets of brackets are fixedly installed at the top of the base plate. A bidirectional lead screw is rotatably installed inside the two sets of brackets. A drive motor is fixedly installed on one side of one set of lead screws. Two sets of downward inclined blocks in opposite directions are threaded to the outer side of the bidirectional lead screw. Two sets of upward inclined blocks in opposite directions are fixedly installed at the bottom of the lifting platform. A moving block is fixedly installed at the bottom of each set of downward inclined blocks. The two sets of moving blocks are slidably installed inside the base plate.

[0008] Preferably, the upper inclined blocks and lower inclined blocks located on the same side are matched, and the interior of the two sets of upper inclined blocks is provided with inclined sliding grooves, and the two sets of lower inclined blocks are slidably installed in the corresponding inclined sliding grooves.

[0009] Preferably, the two sets of bevel gears mesh with the corresponding bevel gears, the bottom of each support leg is fixedly equipped with an anti-slip pad, and one end of the rotating rod is fixedly installed on the output end of the micro motor.

[0010] Preferably, the two ends of the two sets of springs are respectively fixedly installed on one side of the inner wall of the corresponding frame and on one side of the corresponding insert rod.

[0011] Preferably, the bidirectional lead screw is fixedly installed on the output end of the drive motor, and a slide rail is provided inside the base plate, with the two sets of moving blocks slidably installed inside the slide rail.

[0012] In this utility model, a heat dissipation base for a projector is provided, which moves the connecting plate by setting a pull ring, thereby moving the first and second insertion rods. The spring contracts, and the filter is disassembled when the second insertion rod is disengaged from the filter.

[0013] In this invention, a heat dissipation base for a projector is described. A drive motor rotates a bidirectional lead screw, which in turn moves a moving block relative to it. Through the cooperation of the upper and lower inclined blocks, the upper inclined block is lifted. A limiting rod restricts the lifting platform, thus achieving the lifting and lowering of the platform. During the lifting process, the limiting rod ensures that the platform can only move vertically, preventing instability such as swaying or tilting. This not only improves the stability of the projector during use but also helps protect it from potential damage caused by instability.

[0014] This utility model features a reasonable structural design. The micro motor drives the rotating rod and bevel gear one to rotate, and then, through the interaction of bevel gear one and bevel gear two, the rotating shaft and cooling fan rotate synchronously. This active cooling method can quickly and effectively dissipate the heat generated during projector operation, preventing overheating from affecting performance, shortening lifespan, or even causing malfunctions.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5A heat dissipation base for a projector includes: a projector body 1, a frame 16 connected to the bottom of the projector body 1, a base body 2 fixedly mounted on the outside of the frame 16, a rotating rod 12 rotatably mounted inside the projector body 1, two sets of bevel gears 13 fixedly mounted on the outside of the rotating rod 12, a support plate 18 fixedly mounted inside the frame 16, two sets of rotating shafts 14 rotatably mounted inside the support plate 18, bevel gears 21 fixedly mounted on the top of each of the two sets of rotating shafts 14, and a cooling fan fixedly mounted on one end of each of the two sets of rotating shafts 14. 15. The bottom of the frame 16 is movably abutted against the filter screen 17. The bottom of the base body 2 is fixedly installed with four sets of support legs 3. A micro motor 11 is fixedly installed on one side of the projector body 1. Two sets of plug rods 1 24 are movably inserted into the filter screen 17. Two sets of plug rods 25 are movably inserted into the frame 16. Springs 26 are sleeved on the outside of the two sets of plug rods 25. The plug rods 1 24 and plug rods 25 on the same side are fixedly installed with the same connecting plate 23. Pull rings 22 are fixedly installed on one side of the two sets of connecting plates 23.

[0023] In this embodiment, a lifting platform 10 is fixedly installed at the bottom of the four sets of support legs 3. Four sets of limiting rods 4 are slidably installed inside the lifting platform 10. A base plate 5 is fixedly installed at the bottom of the four sets of limiting rods 4. Two sets of brackets 20 are fixedly installed at the top of the base plate 5. Two bidirectional lead screws 7 are rotatably installed inside the two sets of brackets 20. A drive motor 6 is fixedly installed on one side of one set of lead screws. Two sets of downward inclined blocks 8 with opposite directions are threaded to the outside of the bidirectional lead screws 7. Two sets of upward inclined blocks 9 with opposite directions are fixedly installed at the bottom of the lifting platform 10. Movable blocks 19 are fixedly installed at the bottom of each set of downward inclined blocks 8. The two sets of movable blocks 19 are slidably installed inside the base plate 5. This height adjustment function can adjust the projector body 1 to the optimal projection height according to different usage needs and environments, thereby improving the projection effect and viewing experience.

[0024] In this embodiment, the upper inclined block 9 and the lower inclined block 8 located on the same side are matched. The two sets of upper inclined blocks 9 are provided with inclined sliding grooves inside, and the two sets of lower inclined blocks 8 are slidably installed in the corresponding inclined sliding grooves. Compared with the direct vertical lifting method, the inclined plane transmission can reduce impact and vibration, and protect the structural integrity of the projector body 1 and the heat dissipation base body 2.

[0025] In this embodiment, two sets of bevel gears 13 mesh with corresponding bevel gears 21. Anti-slip pads are fixedly installed on the bottom of each support leg 3. One end of the rotating rod 12 is fixedly installed on the output end of the micro motor 11, ensuring that the power of the micro motor 11 is accurately transmitted to the rotating shaft 14, thereby driving the cooling fan 15 to rotate stably. This helps improve heat dissipation and ensures stable temperature of the projector during operation.

[0026] In this embodiment, the two ends of the two sets of springs 26 are respectively fixedly installed on one side of the inner wall of the corresponding frame 16 and one side of the corresponding insertion rod 25. The entire disassembly and installation process does not require any tools, making the operation simple and convenient. Users can clean or replace the filter screen 17 anytime and anywhere as needed, improving the convenience of use.

[0027] In this embodiment, the bidirectional lead screw 7 is fixedly installed on the output end of the drive motor 6. The base plate 5 has a slide rail inside, and two sets of moving blocks 19 are slidably installed in the slide rail. The slide rail inside the base plate 5 provides a clear movement track for the moving blocks 19. The moving blocks 19 slide in the slide rail, which can ensure that their movement direction always remains straight, and avoid the moving blocks 19 from deflecting or tilting due to uneven force or other factors.

[0028] In this embodiment, during use, the micro motor 11 drives the rotating rod 12 to rotate, which in turn drives the bevel gear 13 to rotate. Through the interaction of the bevel gear 13 and the bevel gear 21, the bevel gear 21 is driven to rotate, which in turn drives the rotating shaft 14 to rotate on the support plate 18, thereby driving the cooling fan 15 to rotate synchronously. The micro motor 11 drives the rotating rod 12 and the bevel gear 13 to rotate, which in turn drives the rotating shaft 14 and the cooling fan 15 to rotate synchronously. This active cooling method can quickly and effectively dissipate the heat generated by the projector during operation, preventing the projector from overheating, affecting its performance, shortening its lifespan, or even causing malfunctions.

[0029] By pulling the pull ring 22 outward, the first insertion rod 24 and the second insertion rod 25 are moved outward, and the spring 26 retracts. When the second spring 26 disengages from the filter screen 17, the filter screen 17 can be quickly disassembled. This makes the operation very simple when the filter screen 17 needs to be cleaned or replaced due to accumulated dust or debris. No complicated tools or cumbersome steps are required, which greatly saves maintenance time and effort.

[0030] The drive motor 6 is started, which drives the bidirectional lead screw 7 to rotate on the bracket 20. This causes the moving block 19 to move relative to the slide rail, which in turn causes the lower inclined block 8 to move relative to the slide rail. The lower inclined block 8 slides in the inclined groove of the upper inclined block 9, thereby lifting the upper inclined block 9. The lifting platform 10 is then restricted by the limit rod 4, thus realizing the up and down movement of the lifting platform 10. Due to the high precision of the lead screw drive, the movement distance of the moving block 19 in the slide rail can be ensured to be very accurate. This allows the relative movement distance of the lower inclined block 8 to be precisely controlled. This precise control allows the up and down movement height of the lifting platform 10 to be accurately adjusted to the required position, meeting the height requirements of different projectors and the needs of different usage scenarios.
