Description

Technical Field

[0001] This utility model relates to the technical field of RV ventilation fans, and in particular to a rainproof ventilation fan for RVs. Background Technology

[0002] RVs are a type of fashionable vehicle imported from abroad. They are equipped with home-like amenities such as bedding, stoves, refrigerators, cabinets, sofas, dining tables and chairs, washing facilities, air conditioning, televisions, and audio systems. They can be divided into driving areas, living areas, bedroom areas, bathroom areas, and kitchen areas. RVs integrate "clothing, food, shelter, and transportation," realizing a fashionable product that allows one to "live while traveling and travel while living." Due to the limited space inside an RV, natural ventilation is relatively difficult, especially in small spaces like bathrooms and toilets where odors are prone to develop. Therefore, timely ventilation is crucial.

[0003] The flap opens in an arc shape relative to the frame. One end of the flap is hinged to the frame (called the connecting end, meaning rear-mounted push), and the other end of the flap opens or closes by changing the angle relative to the frame (called the movable end). Currently, all RV ventilation fan extension covers on the market are rear-mounted push-out extension covers. The push rod device is long, which causes the cover to sway from side to side, greatly increasing the pushing force of the motor and shortening the service life of the motor. Utility Model Content

[0046] Furthermore, as a preferred embodiment, the flip cover 1 is provided with a connecting rod track fixing frame 27 extending along its length direction; one end of the connecting double rod assembly 3 is slidably connected to the connecting rod track fixing frame 27; the other end of the connecting double rod assembly 3 is rotatably connected to the frame assembly and forms a movable end mounting area; when the flip cover 1 is closed with the frame assembly, the movable end mounting area of ​​the connecting double rod assembly 3 is closer to the movable end of the flip cover 1 relative to the connecting rod track fixing frame 27.

[0047] Furthermore, as a preferred embodiment, the frame component includes an outer frame 6, a border 7, a decorative frame 8, an inner frame 10, and a panel frame 23. The decorative frame 8 is nested inside the outer frame 6, the inner frame 10 is disposed inside the decorative frame 8, the border 7 is disposed on the lower side of the outer frame 6, and the panel frame 23 is disposed on the lower side of the border 7.

[0048] Specifically, in this embodiment, the outer frame 6 is hollow in the middle, and a decorative frame 8 is fitted inside the outer frame 6. The decorative frame 8 is also hollow in the middle, and an inner frame 10 is provided inside the decorative frame 8. A mounting hole 25 is provided in the middle of the inner frame 10, and a mounting plate is provided on the outer side of the inner frame 10. The mounting plate is used to install the entire ventilation fan on the top of the RV. A mesh cover 16 is provided in the middle of the inner frame 10 to prevent dust, gravel, and debris from entering the RV. The panel frame 23 is fastened to the outer side of the outer frame 6, and the two are connected by a detachable snap-fit. A connecting double rod assembly 3 is provided at the edge of the inner frame 10, and a first drive assembly is provided on the inner frame 10. The first driving device 13 is a spur gear motor 12 assembly. The first driving device 13 includes a spur gear motor 12 and a reduction gearbox. A worm gear is connected to the reduction gearbox, and a turbine component that cooperates with the worm gear is connected to the worm gear. One end of the turbine component is connected to the worm gear, and the other end of the turbine component is connected to the connecting double rod assembly 3. When the spur gear motor 12 starts, the connecting double rod assembly 3 moves. The speed of the spur gear motor 12 is reduced by setting the reduction gearbox, thereby reducing the movement speed of the connecting double rod assembly 3. The connecting double rod assembly 3 is a connecting rod, which is the prior art and will not be described in detail here. The rotation of the spur gear motor 12 is converted into linear motion, thereby driving the movement of the connecting double rod assembly 3.

[0049] Specifically, in this embodiment, a flip cover 1 is movably provided on the upper side of the outer frame 6. One end of the flip cover 1 is hinged to the outer frame 6, and this end is the connecting end. When the flip cover 1 needs to be opened, the connecting end rotates relative to the outer frame 6 by changing the angle. The other end of the flip cover 1 is not connected to the outer frame 6, and this end is the movable end. When the outer frame 6 is closed, the movable end of the outer frame 6 covers the outer frame 6, thus blocking the hollow part of the outer frame 6. When the outer frame 6 is opened, the movable end of the flip cover 1 moves open, thereby opening the hollow part of the outer frame 6, so that when the flip cover 1 moves, it moves closer to or further away from the outer frame 6. There is a gap between the flip cover 1 and the outer frame 6, so that air can enter the RV through this gap for ventilation. The flip cover 1 can cover or open the hollow part of the outer frame 6.

[0050] Specifically, in this embodiment, the flip cover 1 is provided with a connecting rod track fixing bracket 27, the connecting rod track fixing bracket 27 is provided with a sliding groove, and the connecting double rod assembly 3 is provided with a slider.

The sliding groove is inclined downward from the movable end to the connecting end. When the flip cover 1 is closed, the slider of the connecting double rod assembly 3 is located in the resting groove near the connecting end. When the flip cover 1 is opened, the connecting double rod assembly 3 moves, driving the slider to slide along the sliding groove, thereby causing the slider to move towards the side closer to the movable end. After the flip cover 1 is fully opened, the slider of the connecting double rod assembly 3 is located in the resting groove near the movable end. In this way, when the connecting double rod assembly 3 moves, the slider can lift or lower the flip cover 1 when it moves along the sliding groove. The connecting double rod assembly 3 is rotatably connected to the inner frame 10 and forms a movable end mounting area. When the flip cover 1 is closed with the frame assembly, the movable end mounting area of ​​the connecting double rod assembly 3 is closer to the movable end of the flip cover 1 than the connecting rod track fixing bracket 27. When the connecting rod track fixing bracket 27 is set in the middle position of the flip cover 1, the movable end installation area of ​​the connecting double rod assembly 3 is set at the front end (front position) of the inner frame 10 and its length is shortened, so that the opening angle of the flip cover 1 is smaller. This not only allows for ventilation but also reduces the possibility of rain leaking into the RV on rainy days, solving the problem of the RV not being able to ventilate on rainy days. The inner frame 10 is equipped with a control circuit board 9 that is connected to the spur gear motor 12 of the first drive device 13.

[0051] Specifically, in this embodiment, by setting a connecting double rod assembly 3 at the front end of the frame assembly, the length of the connecting double rod assembly 3 is shortened, the stability of the flip cover 1 is enhanced, and the extension and reduction height range is 0-10°. Within this extension and reduction range, rainwater will not enter the RV in wind and rain, greatly improving the rainproof effect and ventilation, greatly improving the use efficiency of the first drive device 13 and eliminating the need to increase the pushing force of the motor 12, and increasing the service life of the first drive device 13.
