Abstract
Description
Technical Field
[0001] This utility model relates to the field of RV-related technology, and in particular to a heat insulation device for RVs. Background Technology
[0002] Trailer caravans are a type of RV. Unlike motorhomes, trailer caravans are not powered by their own engines and require an additional vehicle to tow them. Depending on their appearance and features, trailer caravans can be divided into Type A trailer caravans, Type B trailer caravans, Type C trailer caravans, Type D trailer caravans, as well as Type A and Type B mobile villa caravans.
[0003] Since many RVs are enclosed and have poor insulation, it is usually necessary to install insulation devices on the roof of the RV for insulation. For example, a type of insulation device for towable RVs, CN214057367U, can be used to move the support plate relative to each other by pulling the pull plate. This causes the compression spring, tension spring and buffer spring to be subjected to relative compression force, which moves the positioning plate into the placement compartment. The insulation plate can then be installed or removed between the fixed plates, which greatly improves the efficiency of insulation plate installation and removal and makes it more convenient for users.
[0004] However, most insulation panels are porous, utilizing the pores inherent in the material itself for insulation. Because the thermal conductivity of air within the pores is very low, this type of insulation panel can provide excellent insulation. Since the insulation panel is located on the roof of the RV, it is easily wetted when it rains. The diffusion of vapor and the movement of water molecules in the pores will play a major role in heat transfer. Because the thermal conductivity of water is greater than that of air, this causes a significant increase in the effective thermal conductivity of the material, resulting in a decrease in the insulation performance of the insulation panel. Utility Model Content
[0005] In view of the above-mentioned prior art, the present invention provides a heat insulation device for RVs, which mainly solves the technical problems existing in the background art.
[0006] To achieve the above objectives, the technical solution of this utility model embodiment is implemented as follows:

[0026] Example 1
[0027] Please refer to the attached document. Figure 1-3 This application provides a heat insulation device for RVs, including a heat insulation plate 1, a C-shaped fixing plate 2, and a rainproof device 3. The C-shaped fixing plate 2 is fixedly installed on the top of the vehicle body. A groove 4 is provided on the inner side of the C-shaped fixing plate 2, and the heat insulation plate 1 is installed in the groove 4. A sealing plate 5 is installed at the opening of the C-shaped fixing plate 2. The sealing plate 5 has a threaded hole, and the C-shaped fixing plate 2 is threadedly connected to the sealing plate 5 by bolts 6. Sliding grooves 7 are provided on both the left and right sides of the top of the C-shaped fixing plate 2. The rainproof device 3 includes a drive mechanism 301 and a tarpaulin 302. The movable tarpaulin 302 is fixedly connected to the movable tarpaulin 302 support frame. The lower end of the support frame near the front of the C-shaped fixing plate 2 in the movable tarpaulin 302 support frame is fixedly connected to the C-shaped fixing plate 2. The lower ends of other support frames in the movable tarpaulin 302 support frame are fixedly installed with the sliders 304 that move along the slide groove 7. The driving mechanism 301 drives the sliders 304 at the lower end of the support frame at the rear of the movable tarpaulin 302 support frame to reciprocate within the slide groove 7.
[0028] In use, the heat insulation board 1 is installed into the C-shaped fixing plate 2 along the groove 4, and the sealing plate 5 is pushed into the groove 4, with the outer side of the sealing plate 5 flush with the opening of the C-shaped fixing plate 2. The sealing plate 5 and the C-shaped fixing plate 2 are then threaded together with bolts 6. This completes the installation of the heat insulation board 1. The structure is simple and easy to operate, improving the efficiency of installing and disassembling the heat insulation board 1 and making it convenient for users. After the heat insulation board 1 is installed, when it rains, the slider 304 under the support frame at the rear of the movable tarpaulin 302 bracket is driven by the drive device to move within the slide groove 7. As the rear support frame moves, it drives all the rear support frames to move forward along the slide groove 7, so that the movable tarpaulin 302 bracket can be unfolded. This ensures that the movable tarpaulin 302 bracket can cover and protect the heat insulation board 1 in rainy weather, preventing the heat insulation board 1 from getting wet and damp, and improving the service life of the heat insulation board 1. When the weather is sunny, the drive device drives the slider 304 to slide in the opposite direction. As the rear support frame moves, it drives all the rear support frames to move along the slide groove 7, driving the tarpaulin 302 to retract and expose the heat insulation board 1 so that the heat insulation board 1 can play its heat insulation role.
[0029] Specifically, the sealing plate 5 is provided with a handle 8 on its outer side. The sealing plate 5 can be pulled out or pushed in by the handle 8, which facilitates the subsequent fixing operation of the sealing plate 5 and the C-shaped fixing plate 2.
[0030] Specifically, the drive mechanism 301 includes a motor 3011, a chain 3012, a front gear 3013, and a rear gear 3014. The side wall of the C-shaped fixing plate 2 is provided with a drive groove 3015 below the slide groove 7. The front gear 3013 and the rear gear 3014 are rotatably connected to the inner wall of the drive groove 3015 through a connecting rod. The front gear 3013 and the rear gear 3014 are connected through the chain 3012. The slide groove 7 is provided with a first through hole 9 in the middle. The slider 304 at the lower end of the support frame at the tail of the movable tarpaulin 302 passes through the first through hole 9 and is fixedly connected to the chain 3012. The output shaft of the motor 3011 is fixedly connected to the front gear 3013. The motor 3011 provides power to drive the front gear 3013 to rotate. The front gear 3013 drives the chain 3012 to rotate. The chain 3012 drives the first support frame in the movable tarpaulin 302 support frame to move. While the first support frame moves, it drives all the subsequent support frames to move along the slide groove 7, so that the movable tarpaulin 302 support frame can achieve the effect of telescopic opening and closing. This ensures that the movable tarpaulin 302 support frame can cover and protect the heat insulation board 1 in rainy weather, prevent the heat insulation board 1 from getting wet and damp, and improve the service life of the heat insulation board 1. The function of the rear gear 3014 is to cooperate with the front gear 3013 to ensure the tension of the chain 3012.
[0031] Specifically, the C-shaped fixing plate 2 is equipped with the driving device on both the left and right sides, and a channel is provided between the front gears 3013 on both sides. The front gears 3013 on both sides are connected by a rotating shaft 10. By setting the same front gears 3013, rear gears 3014 and chain 3012 on the left and right sides of the C-shaped fixing plate 2, and connecting the front gears 3013 on both sides together through the rotating shaft 10, the motor 3011 can drive the front gears 3013 on both sides to move synchronously, ensuring the synchronous forward or backward movement of the movable tarpaulin 302 support and improving the stability of the movable tarpaulin 302 support.
[0032] Specifically, in the movable tarpaulin 302 support frame, the edge of the tarpaulin 302 near the front of the C-shaped fixing plate 2 is fixedly connected to the top of the C-shaped fixing plate 2. The movable tarpaulin 302 support frame is sealed and fixed to the front end of the C-shaped fixing plate 2 by the front edge of the tarpaulin 302, so that the front end of the tarpaulin 302 is closed on the C-shaped fixing plate 2, preventing rainwater from falling onto the heat insulation plate 1 and causing damage to the heat insulation plate 1.
[0033] Specifically, at the support frame at the rear of the movable tarpaulin 302 support frame, the bottom of the tarpaulin 302 is attached to the top of the C-shaped fixing plate 2. By attaching the bottom of the tarpaulin 302 at the support frame at the rear of the movable tarpaulin 302 support frame to the top of the C-shaped fixing plate 2, the front end of the tarpaulin 302 is sealed on the C-shaped fixing plate 2, preventing rainwater from falling onto the heat insulation plate 1 and causing damage to the heat insulation plate 1.
[0034] Specifically, the top of the support frame on the movable tarpaulin 302 bracket is arc-shaped. Designing the support frame of the movable tarpaulin 302 bracket in an arc shape allows rainwater to flow down the arc-shaped tarpaulin 302 when it is in use, preventing water accumulation on the movable tarpaulin 302 bracket and avoiding water spilling onto the heat insulation board 1 when the movable tarpaulin 302 bracket is closed, thus improving the service life of the heat insulation board 1.
[0035] Example 2
[0036] Please refer to the appendix. Figure 1-3 The difference between this embodiment and Embodiment 1 is that a controller 11 is fixedly installed on the front of the C-shaped fixing plate 2, and the controller 11 is electrically connected to the motor 3011. The controller 11 is used to operate and control the rotation of the motor 3011, so as to achieve a more convenient and intelligent operation and control effect.
[0037] Specifically, a distance sensor 12 is fixedly installed at the rear end of the side of the C-shaped fixing plate 2 to detect the distance to the slider 304 and obtain a distance signal. The distance sensor 12 is signal-connected to the controller 11. When the controller 11 receives a distance signal that is less than a set value or greater than a preset value, it controls the motor 3011 to stop rotating in the same direction. When the slider 304 slides to the front or rear end of the slide groove 7, the controller automatically controls the motor 3011 to stop rotating in the same direction. When the tarpaulin 302 is fully unfolded or retracted, the controller can automatically control the motor 30118 to stop rotating to avoid damaging the device.
[0038] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. The protection scope of this utility model should be determined by the protection scope of the stated claims.
