Technical Field
[0001] This utility model relates to the technical field of RVs, and in particular to the body of a towable RV. Background Technology
[0002] A caravan is a mobile dwelling without its own power system, requiring a tow truck to move. It combines living and transportation functions, providing travelers with a flexible and comfortable accommodation experience while maintaining the independence of the tow truck.
[0003] The existing Chinese utility model patent with application number CN202022196815.5 relates to a trailer caravan body, including a frame, top frame, base, head frame, storage compartment, windproof glass, body frame and central load-bearing frame, which can optimize the wind structure and lighting effect of the caravan, making the caravan more functional.
[0004] However, in actual use, the aforementioned device does not have a semi-open leisure area, nor does it have an area for viewing the outside world inside the vehicle, and the observation of the outside world through the glass is greatly limited. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a towable caravan body that connects to a towing vehicle via a towing device to provide traction power to the caravan body, opens the head area of the caravan body via an opening device to provide a viewing platform for the occupants, and increases the sealing of the opening area via a sealing device, thereby improving the practicality of the device.
[0006] This utility model discloses a towable caravan body, comprising a towing device, an opening device, and a sealing device. The opening device is installed on the towing device, and the sealing device is installed on the towing device. The towing device connects to the towing vehicle to provide traction power to the caravan body. The opening device opens the head area of the caravan body to provide a viewing platform for the occupants. The sealing device increases the sealing of the opening area, thereby improving the practicality of the device.
[0007] Preferably, the traction device includes a vehicle body, wheels, a rectangular groove, a mounting frame, a traction support shaft, and a traction link. Multiple sets of wheels are mounted on the lower part of the vehicle body. A rectangular groove is provided on the front surface of the vehicle body, and the mounting frame is installed within the rectangular groove. One end of the traction link is fitted onto the traction support shaft, and the upper and lower ends of the traction support shaft are welded to the mounting frame. The multiple sets of wheels enable the vehicle body to move, the rectangular groove provides storage space for the traction link, and the traction support shaft enables the traction link to rotate. During traction, the link moves out of the rectangular groove, and when the vehicle body does not need to move, it retracts into the rectangular groove, improving the practicality of the device.
[0008] Preferably, it also includes an internal threaded hole, a limiting bolt, and a circular hole. Two sets of internal threaded holes are provided on the side of the traction support shaft, which are located at the front and left sides of the traction support shaft, respectively. A circular hole is provided on the end of the traction link that connects to the traction support shaft. The limiting bolt can pass through the circular hole and connect with the internal threaded hole on the traction support shaft. By connecting the limiting bolt through the circular hole and the internal threaded hole, the position of the traction link is fixed, keeping the traction link pointing towards the front of the vehicle body and in a stable position during driving, thus improving the practicality of the device.
[0009] Preferably, the opening device includes a rotating shaft, a geared motor, a tilting window, and a windshield. The front of the vehicle body has an inclined surface with a rectangular window. A rotating shaft is installed at the lower part of the rectangular window. A geared motor is installed at the front of the vehicle body, and its output is connected to the rotating shaft. The tilting window is connected to the rotating shaft, and the windshield is mounted on the tilting window. By activating the geared motor, power is transmitted to the rotating shaft, causing it to rotate. The rotating shaft then rotates the tilting window, thereby controlling the opening and closing of the window at the front of the vehicle body, providing an open area for the vehicle body. The windshield facilitates observation of the outside by occupants inside the vehicle, improving the practicality of the device.
[0010] Preferably, the sealing device includes a support platform, a sealing groove, a sealing ring, a water guide plate, and a water guide channel. The support platform is provided on the front face of the vehicle body, the sealing groove is provided on the edge of the window on the front face of the vehicle body, the sealing ring is provided on the edge of the rear face of the flip-up window, the water guide plate is provided on the upper part of the flip-up window, the water guide channel is provided on the front part of the upper end of the vehicle body, and the rear part of the water guide plate extends to the upper side of the water guide channel. The support platform provides support for the flip-up window, allowing the flip-up window to be placed horizontally on the support platform, which is convenient for supporting objects. The sealing groove and sealing ring improve the sealing performance of the opening device, reducing the impact of thunderstorms on the vehicle. The water guide plate guides rainwater during driving, and together with the water guide channel, guides rainwater to the rear and sides of the vehicle body, improving the practicality of the device.
[0011] Preferably, it also includes a mechanical lock, with a mechanical lock provided at the front of the upper end of the vehicle body and a locking tongue provided at the corresponding position on the rear end of the water guide plate; the mechanical lock fixes the position of the water guide plate, reducing the vibration amplitude of the flip-up window during driving and in windy weather, thus improving the stability and practicality of the device.
[0012] Preferably, the device also includes a supporting wooden board and limiting slots. A set of limiting slots is provided on the left and right sides of the rear end face of the flip window. The left and right sides of the supporting wooden board can enter into the limiting slots and the supporting wooden board is placed on the rear end face of the flip window. The limiting slots enable the supporting wooden board to be placed stably on the rear end face of the flip window. The supporting wooden board supports objects, which makes it convenient for people to place their personal belongings or food items when they are looking at the scenery from the front of the vehicle. It is also easy to install and remove, which improves the practicality of the device.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: it connects to the towing vehicle through the traction device to provide traction power for the RV body; it opens the head area of the vehicle body through the opening device to provide a viewing platform for the people inside the vehicle; and it increases the sealing of the opening area through the sealing device, thereby improving the practicality of the device.
