Description

Technical Field

[0001] The invention relates to the technical field of recreational vehicles, and in particular to a wind-free structure for a recreational vehicle air conditioner. Background Art

[0002] With the improvement of people's living standards and the growing demand for outdoor travel and free travel, RVs, as a multifunctional means of transportation that integrates "clothing, food, housing and transportation", are becoming more and more popular among the public. Among the various facilities in RVs, the air conditioning system plays a vital role. It can create a comfortable temperature and humidity environment in the car, allowing users to enjoy a comfortable rest and living space during the journey. RVs are divided into two types: self-propelled and trailer-type. With the continuous advancement of automobile technology, RVs are now equipped with air conditioners.

[0003] The vast majority of RVs on the market are equipped with roof-mounted parking air conditioners. The roof-mounted parking air conditioners are relatively high, and they can form relatively uniform air convection in the car. When the air conditioner is turned on in cooling mode, the cold air diffuses from the roof to the bottom, which can better cover the entire interior space of the car.

[0004] However, the existing device has the following shortcomings during use:

[0005] When the existing RV air conditioner is turned on, it will blow a large amount of air in a certain direction. This cold air or hot air will blow directly onto the human body, which can easily cause discomfort after a long time and affect the comfort experience of RV users.

[0006] Therefore, we proposed a windless structure for RV air conditioner in order to solve the above problems. Summary of the invention

The cold air or hot air blown out by the air conditioner can be dispersed into multiple soft sub-air flows by utilizing the multiple wind dispersion holes distributed on the surface of the wind dispersion piece. The wind dispersion piece can not only fully disperse the wind blown out of the air outlet, but also widen the initial diffusion range of the wind.

[0018] Preferably, a second reduction motor is fixedly mounted on one side of the air outlet frame, and an output end of the second reduction motor movably passes through the air outlet frame and is fixedly connected to one of the rotating shafts.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The present invention provides a windless mechanism. When the user wants to enjoy a comfortable experience without wind, the first reduction motor is started, and the meshing transmission of the first bevel gear and the second bevel gear drives the threaded rod to rotate, so that the movable plate moves, and the wind dispersion member is pulled out from the first fixed shell. By utilizing a plurality of wind dispersion holes distributed on the surface of the wind dispersion member, when the wind blown out by the air conditioner hits the wind dispersion member, the airflow can be quickly dispersed through the wind dispersion holes, and is converted from the originally concentrated strong wind into a plurality of soft sub-airflows. Compared with the traditional air-conditioning wind dispersion method, the wind dispersion member can not only fully disperse the wind blown out of the air outlet, but also widen the initial diffusion range of the wind. Compared with the traditional wind dispersion structure, the wind blown out from the wind dispersion member has a larger wind dispersion distance and wind dispersion area, which effectively reduces the discomfort caused by the air conditioning airflow directly blowing on the human body, creates a comfortable use environment for users, and improves the use experience. The problem that the existing RV air conditioner will blow a large amount of air in a certain direction after being turned on, and this cold wind or hot wind will directly blow on the human body, which is easy to cause discomfort after a long time, affecting the comfortable experience of the RV user.

[0021] 2. The present invention sets a dustproof mechanism. When dustproof is needed, the movable plate contacts the magnetic part, and then the electromagnet is energized to generate magnetism and attract the magnetic part. Then, the movable plate moves in the opposite direction to pull the dustproof part out of the second fixed shell, blocking the air outlet of the air outlet frame, thereby playing a dustproof role and preventing dust and other impurities from entering the air outlet frame and the air conditioner body, which helps to keep the air conditioner and the car environment clean, reduce the frequency of cleaning and maintenance, and extend the service life of the air conditioner.

[0022] 3. The present invention starts the second reduction motor through the wind direction adjustment mechanism, and its output end drives one of the rotating shafts to rotate. Relying on the transmission connection between the sprocket and the chain, multiple rotating shafts can rotate synchronously, thereby driving the air guide grille to rotate accordingly. The direction of air outlet can be flexibly changed to meet the user's needs for different wind directions. The wind can be directed to different positions in the vehicle, thereby improving the flexibility and applicability of the air outlet of the air conditioner, and better adapting to the cooling or heating needs of different areas in the RV.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0033] like Figure 1-Figure 8 As shown, the present invention provides a technical solution: a RV air conditioner windless structure, comprising an air conditioner body 1 and an air outlet frame 2, the air outlet frame 2 is installed at the bottom of the air conditioner body 1 by bolts, the air outlet frame 2 is located at the air outlet of the air conditioner body 1, and the connection between the air conditioner body 1 and the air outlet frame 2 is sealed by a sealing strip, a windless mechanism 3 is arranged in the air outlet frame 2, a driving mechanism 4 is arranged on one side of the air outlet frame 2, and a dustproof mechanism 5 and a wind direction adjustment mechanism 6 are arranged in the air outlet frame 2;

[0034] The windless sensing mechanism 3 includes two placement grooves 301, and the two placement grooves 301 are opened on the inner surface of the air outlet frame 2. A threaded rod 302 is rotatably connected in one of the placement grooves 301, and a fixed rod 303 is fixedly connected in the other placement groove 301. A movable plate 304 is movably sleeved on the outer surfaces of the threaded rod 302 and the fixed rod 303. A first fixed shell 305 is fixedly connected to one side of the air outlet frame 2. A first reel 306 is rotatably connected in the first fixed shell 305. The first reel 306 A first coil spring 307 is sleeved on the outer surface, one end of the first coil spring 307 is fixedly connected to the first reel 306, and the other end of the first coil spring 307 is fixedly connected to the first fixed shell 305. A wind dispersing piece 308 is fixedly wound on the outer surface of the first reel 306. The wind dispersing piece 308 is a flexible thin sheet structure, one end of the wind dispersing piece 308 movably passes through the first fixed shell 305 and the air outlet frame 2 and is fixedly connected to the movable plate 304, and a plurality of wind dispersing holes 309 are distributed on the surface of the wind dispersing piece 308.

[0035] like Figure 1 and Figure 8 As shown, the driving mechanism 4 includes a first reduction motor 401, which is fixedly installed on one side of the air outlet frame 2. The output end of the first reduction motor 401 movably passes through the air outlet frame 2 and one of the placement slots 301 and is fixedly connected to a first bevel gear 402. The first reduction motor 401 is used as a power source to provide a stable and reliable driving force, which is convenient for controlling the speed and direction. The power is transmitted through the first bevel gear 402 connected to the output end, which is convenient for subsequent cooperation with the second bevel gear 403 on the threaded rod 302 to drive the windless sensing mechanism 3 to operate, thereby realizing automatic control of the pulling out and retracting of the wind dispersion piece 308, and improving the user operation experience.

[0036] like Figure 8 As shown, the outer surface of the threaded rod 302 is fixedly sleeved with a second bevel gear 403, and the first bevel gear 402 is meshingly connected with the second bevel gear 403. By setting the first bevel gear 402 and the second bevel gear 403, the lateral rotation output by the first reduction motor 401 can be converted into the longitudinal rotation of the threaded rod 302, which is convenient for driving the threaded rod 302 to rotate, and then driving the movable plate 304 to move, ensuring that the wind dispersion member 308 is accurately pulled out or retracted as required, thereby ensuring the stable operation of the windless sensing mechanism 3.

[0037] like Figure 1 and Figure 8 As shown, the dustproof mechanism 5 includes a second fixed shell 501, which is fixedly connected to one side of the air outlet frame 2. The second fixed shell 501 provides a storage space for the dustproof part 504, so that it can be orderly wound and stored when not in use, thereby protecting the dustproof part 504 from damage. At the same time, the second fixed shell 501 is fixed to one side of the air outlet frame 2. The overall structure is compact and does not occupy too much extra space in the RV, so it is convenient to arrange in a limited vehicle environment.

[0038] like Figure 8 As shown, a second reel 502 is rotatably connected inside the second fixed shell 501, and a second coil spring 503 is sleeved on the outer surface of the second reel 502. One end of the second coil spring 503 is fixedly connected to the second reel 502, and the other end of the second coil spring 503 is fixedly connected to the second fixed shell 501. When dust protection is not needed, the second coil spring 503 uses its own elasticity to automatically rotate the second reel 502, so that the dust protection part 504 can be retracted into the second fixed shell 501, and the normal air outlet of the air outlet frame 2 can be restored in time, thereby improving the use efficiency of the equipment and saving time.

[0039] like Figure 8 As shown, a dust-proof piece 504 is fixedly wound around the outer surface of the second reel 502. The dust-proof piece 504 is a flexible thin sheet structure. The dust-proof piece 504 with a flexible thin sheet structure is easy to store, effectively blocking dust from entering the air outlet frame 2 and the air-conditioning body 1, avoiding dust accumulation that affects heat dissipation, reduces cooling and heating efficiency, and pollutes the air inside the vehicle, thereby extending the service life of the air conditioner and ensuring the air quality inside the vehicle.

[0040] like Figure 7 and Figure 8 As shown, one end of the dust-proof member 504 is movable and passes through the second fixed shell 501 and the air outlet frame 2 and is fixedly installed with a magnetic suction member 505. An electromagnet 506 is embedded on one side of the movable plate 304. The dust-proof member 504 and the movable plate 304 are linked by the magnetic attraction cooperation between the electromagnet 506 and the magnetic suction member 505. When the first reduction motor 401 is started to control the movement of the movable plate 304, the magnetic attraction can be cleverly used to drive the dust-proof member 504 to move synchronously, thereby simplifying the operating process, making the opening and closing of the dust-proof function more automated and intelligent, and improving the user's operating convenience.

[0041] like Figure 1 and Figure 6 As shown, the wind direction adjustment mechanism 6 includes a plurality of rotating shafts 601, which are rotatably connected to the air outlet frame 2, and a plurality of air guide grille plates 602 are fixedly sleeved on the outer surfaces of the plurality of rotating shafts 601. Through the combination of a plurality of rotating shafts 601 and air guide grille plates 602, the air outlet direction can be adjusted to meet the personalized needs of passengers in different positions in the RV for wind direction, optimize the air circulation in the car, evenly distribute the cold air or hot air, enhance the use effect of the air conditioner, and improve the comfort level in the car.

[0042] like Figure 6 As shown, one end of a plurality of rotating shafts 601 is movably inserted into the air outlet frame 2, a plurality of sprockets 603 are fixedly sleeved on the outer surfaces of the plurality of rotating shafts 601, and a plurality of chains 604 are transmission-connected to the outer surfaces of the plurality of sprockets 603. The transmission connection between the sprockets 603 and the chains 604 ensures that when one of the rotating shafts 601 rotates driven by the second reduction motor 605, the remaining rotating shafts 601 can rotate synchronously, thereby realizing coordinated action of a plurality of air guide grille plates 602, avoiding abnormal rotation of individual air guide grille plates 602, ensuring consistency and accuracy of wind direction adjustment, and improving adjustment efficiency.

[0043] like Figure 3 and Figure 4 As shown, a second reduction motor 605 is fixedly installed on one side of the air outlet frame 2, and the output end of the second reduction motor 605 is movable through the air outlet frame 2 and fixedly connected to one of the rotating shafts 601. The second reduction motor 605 is used as a power source for adjusting the wind direction. By controlling the forward and reverse rotation and speed of the second reduction motor 605, it is convenient to control the rotation angle of the rotating shaft 601, and then flexibly adjust the direction of the air guide grille plate 602 to achieve control of the wind direction and meet the diverse needs of users.

[0044] The usage and working principle of this device: the air conditioner body 1 is installed to the top of the RV, and the air outlet frame 2 is installed to the bottom of the air conditioner body 1 and is located at the air outlet of the air conditioner body 1. When in use, start the air conditioner body 1 to make it operate normally to blow out cold air or hot air. The air is blown out from the air outlet of the air conditioner body 1 and enters the air outlet frame 2.

[0045] Adjust the wind direction. If the user needs to adjust the wind direction, start the second reduction motor 605. The output end of the second reduction motor 605 drives one of the rotating shafts 601 fixedly connected to it to rotate. Since the outer surfaces of several rotating shafts 601 are fixedly sleeved with sprockets 603, and the sprockets 603 are connected through chains 604, when one of the rotating shafts 601 rotates, the other rotating shafts 601 will rotate synchronously, so that the air guide grille plate 602 fixedly sleeved on the rotating shaft 601 will rotate accordingly, thereby changing the direction of the air outlet, meeting the user's needs for different wind directions, and directing the wind to different positions in the vehicle.

[0046] When the windless mode is turned on and the user wants to enjoy a comfortable experience without wind, the first reduction motor 401 is started, and the output end of the first reduction motor 401 drives the first bevel gear 402 to rotate. Since the first bevel gear 402 is meshed and connected with the second bevel gear 403 fixedly sleeved on the outer surface of the threaded rod 302, the threaded rod 302 is driven to rotate in the placement groove 301. At this time, the movable plate 304 movably sleeved on the outer surface of the threaded rod 302 and the fixed rod 303 will move under the rotation of the threaded rod 302. With the movement of the movable plate 304, the wind dispersion member 308 fixedly connected to the movable plate 304 will be pulled, and one end of the wind dispersion member 308 will be continuously pulled out from the first fixed shell 305, so that the wind dispersion member 308 blocks the air outlet of the air outlet frame 2. Since the surface of the wind dispersion member 308 is provided with a plurality of wind dispersion holes 3 09. Therefore, when the cold air or hot air blown by the air-conditioning body 1 passes through the air dispersion piece 308, it will be dispersed by the multiple air dispersion holes 309, thereby being divided into multiple soft sub-air flows, thereby reducing the discomfort caused by the air-conditioning air flow directly blowing on the human body and achieving the effect of no wind feeling. Compared with the traditional air-conditioning centralized air dispersion method, the air dispersion piece 308 can evenly disperse the wind blown out of the air outlet of the air outlet frame 2. During the propagation process of the evenly dispersed wind, the pressure difference is relatively small, the energy loss is also small, and it can be propagated over a longer distance. When the no wind feeling mode is not needed, by starting the first reduction motor 401 to reverse, with the reverse movement of the movable plate 304, and at the same time under the action of the first coil spring 307, the first scroll 306 can automatically rotate to realize the recovery of the air dispersion piece 308, thereby exposing the air outlet of the air outlet frame 2, and not affecting the normal air outlet.

[0047] The dustproof operation is performed by starting the first reduction motor 401. As the movable plate 304 moves, the movable plate 304 and the magnetic attraction piece 505 come into contact, and then the electromagnet 506 is energized to generate magnetism, which attracts the magnetic attraction piece 505. The first reduction motor 401 is started to reverse. As the movable plate 304 moves in the opposite direction, the dustproof piece 504 fixedly connected to the magnetic attraction piece 505 will be pulled, and one end of the dustproof piece 504 is continuously pulled out from the second fixed shell 501, so that the dustproof piece 504 blocks the air outlet of the air outlet frame 2 to play a dustproof role. When dustproof is not needed, the first reduction motor 401 can be started. As the movable plate 304 moves, the second reel 502 can automatically rotate under the action of the second coil spring 503, so that the dustproof piece 504 is rewound around the second reel 502, and finally the electromagnet 506 is powered off so that the electromagnet 506 and the magnetic attraction piece 505 are no longer attracted to each other.

[0048] The wiring diagram of the air conditioner body 1, the first reduction motor 401, the second reduction motor 605 and the electromagnet 506 in the present invention is common knowledge in the field, and its working principle is a well-known technology. The model is selected according to the actual use, so the control method and wiring arrangement of the air conditioner body 1, the first reduction motor 401, the second reduction motor 605 and the electromagnet 506 are no longer explained in detail.

[0049] 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. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
