Description

Technical Field

[0001] The utility model relates to the technical field of RV expansion cabins, and more specifically, to an RV expansion cabin structure. Background Art

[0002] RV, also known as "home on wheels", has the functions of both "house" and "car", but its attribute is still a car. It is a kind of movable vehicle with basic facilities necessary for home. However, the living cabin of RVs currently seen on the market is limited by the size of space, which greatly limits the living supplies and living facilities that can be carried. Therefore, in order to make the living cabin larger, an expansion cabin is needed;

[0003] When the existing expansion cabin is extended for use, the expansion cabin is in a relatively open space. Especially in cases where the wind is strong or the climatic conditions are relatively severe, the long-term use of the expansion cabin will cause fallen leaves and dust to enter between the awning on the top of the expansion cabin and the expansion cabin. In addition, for some larger expansion cabins, the top area is large and not easy to clean. Therefore, when the expansion cabin is retracted, the fallen leaves and dust will enter the storage mechanism. The long-term accumulation will not only produce a pungent odor, but also cause damage to the storage mechanism of the expansion cabin. Utility Model Content

[0029] Example:

[0030] The following is combined with Figure 1-4 The utility model is described in further detail.

[0031] See also Figure 1-4 The utility model provides a technical solution: a motorhome expansion cabin structure, comprising a car body 1, a car body 1 having an expansion cabin slot 2 on one side thereof, a cabin body 3 arranged in the expansion cabin slot 2, a slide slot 4 on the bottom of the car body 1, slide rails 5 fixedly connected to the bottoms of both sides of the cabin body 3, and two slide rails 5 respectively slidably connected to the two sides of the slide slot 4;

[0032] Limiting grooves 9 are provided on the tops of both sides of the cabin body 3, and semicircular stoppers 10 are fixedly connected to the tops of the two limiting grooves 9. A driving roller 11 is rotatably connected to one side of the inner wall of the cabin body 3. The driving roller 11 is driven by a motor, which is not shown in the figure. A conveyor belt 12 is sleeved on the two semicircular stoppers 10 and the driving roller 11. By setting the limiting grooves 9, the semicircular stoppers 10, the driving roller 11 and the conveyor belt 12, after the expansion cabin is used, the fallen leaves and dust on the top of the expansion cabin are driven out, thereby achieving the effect of cleaning the top of the expansion cabin, which is convenient for the storage operation of the expansion cabin;

[0033] Scrapers 29 are fixedly connected to both sides of the cabin 3. By setting the scrapers 29, the conveyor belt 12 is blocked when entering the cabin 3 to prevent fallen leaves from entering. The two scrapers 29 are respectively located below the two limit grooves 9, and the two scrapers 29 are matched with the surface of the conveyor belt 12;

[0034] A cleaning box 13 is fixedly connected to one side of the inner wall of the cabin 3, and the cleaning box 13 is located on one side of the driving roller 11. The inner wall of the cleaning box 13 is rotatably connected to a brush roller 14, and the brush roller 14 is driven by a motor. The motor used is not shown in the figure, and the brush roller 14 cooperates with the surface of the conveyor belt 12.

[0035] Specifically, a water tank 15 is fixedly connected to the side wall of the cabin 3, a water pump 16 is fixedly connected to the bottom of the inner wall of the water tank 15, a connecting pipe 17 is fixedly connected to the output end of the water pump 16, a plurality of nozzles 18 are fixedly connected to one side of the inner wall of the cleaning box 13, the other end of the connecting pipe 17 passes through the water tank 15 and is connected to the plurality of nozzles 18, a filter screen 19 is fixed to the inner wall of the cleaning box 13, a water pipe 20 is fixedly connected to the bottom of the cleaning box 13, the other end of the water pipe 20 is connected to the water tank 15, a one-way valve 21 is provided on the water pipe 20, a support plate 22 is fixedly connected to one side of the inner wall of the cabin 3, the support plate 22 is located on the side of the driving roller 11 away from the cleaning box 13, a water-absorbing sponge 23 is fixedly connected to the top of the support plate 22, and the water-absorbing sponge 23 cooperates with the surface of the conveyor belt 12.

[0036] By adopting the above technical scheme, the water tank 15, the water pump 16 and the nozzle 18 are used to assist the brush roller 14 in flushing and cleaning the surface of the conveyor belt 12. The filter net 19, the water pipe 20 and the one-way valve 21 are used to filter the waste water generated by cleaning for the next use. The water remaining on the conveyor belt 12 is adsorbed by the absorbent sponge 23.

[0037] Specifically, the top of the carriage 1 is fixedly connected with a sliding frame 6 and a telescopic device 8, the top of the cabin 3 is fixedly connected with a sliding block 7, the sliding block 7 is slidably connected in the sliding frame 6, the output end of the telescopic device 8 is fixedly connected to one side of the cabin 3, and the bottom of the cabin 3 is provided with two storage grooves 24, and the two storage grooves 24 are fixedly connected with fixed shafts 25 and suction cups 28, the two fixed shafts 25 are rotatably connected with telescopic brackets 26, the other ends of the two telescopic brackets 26 are fixedly connected with anti-slip bases 27, and the two telescopic brackets 26 are respectively matched with two suction cups 28.

[0038] By adopting the above technical solution, the sliding frame 6 and the sliding block 7 are used to assist the expansion cabin to be extended and retracted, and the storage slot 24, the fixed shaft 25, the telescopic bracket 26 and the suction cup 28 are used to support it when in use and to store it when not in use.

[0039] The working principle of the utility model is as follows: when in use, after the user has parked the RV stably, the user supplies power through the RV power supply to drive the telescopic device 8 to work, drive the expansion cabin to slide out in the slide groove 4 through the slide rail 5, and slide in the slide frame 6 through the sliding block 7 to assist the expansion cabin to extend and retract. After the extension is completed, the user pulls the telescopic bracket 26 to rotate on the fixed shaft 25, so that the telescopic bracket 26 is perpendicular to the bottom of the cabin body 3, and the telescopic bracket 26 is extended to make the anti-skid base 27 contact the ground for support, and the anti-skid base 27 is used to prevent slipping during support;

[0040] When the RV is parked for a long time, there may be strong wind or bad weather conditions. Since there is a certain gap between the top of the awning and the expansion cabin, the wind will blow the fallen leaves and dust into the gap. The top of some expansion cabins is relatively wide, which is not easy for users to clean. The driving roller 11 works to drive the conveyor belt 12 to transmit, and the fallen leaves and dust on the top of the conveyor belt 12 are driven to fall on both sides of the cabin body 3. The conveyor belt 12 is limited by the scraper 29 to prevent the fallen leaves from entering the cabin body 3;

[0041] The conveyor belt 12 enters the cabin 3, and the water pump 16 works to pump water in the water tank 15, and sprays it out from the nozzle 18 through the connecting pipe 17. The dust adsorbed on the surface of the conveyor belt 12 is cleaned with the assistance of the rotation of the brush roller 14, so as to facilitate the next use. The residual water on the conveyor belt 12 is processed by the water-absorbing sponge 23, and the waste water generated by the cleaning is filtered and processed by the filter net 19, and is put into the water tank 15 through the water pipe 20, so as to facilitate the next use. The user adjusts the length of the telescopic bracket 26 to raise the anti-slip base 27, pushes the telescopic bracket 26 to rotate on the fixed shaft 25, rotates the telescopic bracket 26 and puts it into the storage groove 24, and fixes it by the suction cup 28 for easy storage, and then puts the cabin 3 into the car 1.

[0042] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
