Description

Technical Field

[0001] This invention relates to the field of trailer caravan technology, and in particular to off-road trailer caravans. Background Technology

[0002] Motorhomes are typically large and convenient for off-roading and camping, and they have a variety of uses. Many families buy a motorhome and then purchase a family car for daily travel. Based on the needs of this family car customer group, towable motorhomes have been developed. Towable motorhomes are purchased at a low price and are used to tow their family cars for outdoor travel and camping, satisfying this customer group. However, current off-road motorhomes have high chassis, which makes them unstable when camping in the wild on uneven ground. This causes the beds and tables inside the motorhome to tilt when living inside. Therefore, there is a need for an off-road motorhome that can be parked stably in various terrains. Summary of the Invention

[0003] This invention proposes an off-road towable caravan that solves the problems of unstable parking caused by uneven ground in existing off-road caravans, which leads to tilting of the beds and tabletops inside the caravan.

[0004] The technical solution of this invention is implemented as follows: A towable caravan for off-road use includes a main body, a caravan trim system, and a central control system. The main body comprises a chassis, a rear left wheel, a rear left wheel, a front wheel, and a mounting switch. The front end of the main body has a hook structure for attaching to the rear of a vehicle. The caravan trim system includes a rear leveler, a front leveler, a left trimer, a right trimer, a front trimer, a left caliper, a right caliper, a left balancer, and a right balancer. The rear and front levelers are vertically aligned. The right and left trimers and the rear guide ball are connected in parallel, while the right and left trimers and the front guide ball are connected in series. The right and left trimers are connected to the front guide ball. The balancer is connected in parallel circuits. The central control system includes a photovoltaic panel, an inverter, an electric vehicle charging output terminal, a motorhome in-vehicle power output terminal, and a battery. The central control system is electrically connected to the motorhome balance system. The photovoltaic panel is electrically connected to the central control system through the inverter. The photovoltaic panel and inverter charge the battery through the central control system. The battery supplies power to the electric vehicle charging output terminal through the central control system for charging external new energy vehicles. The battery supplies power to the motorhome in-vehicle power output terminal through the central control system for powering electrical appliances inside the motorhome. The mounting switch (201) is connected in series with the left and right calipers and is powered by the central control system.

[0005] Preferably, the rear leveler controls the left-right horizontal balance of the body, and the front leveler controls the front-back horizontal balance of the body. The rear leveler includes a left guide block, a left guide block, a rear guide ball, and a connecting line A, all of which are conductors. The connecting line A is electrically connected to the rear guide ball. The front leveler includes a front guide block, a rear guide block, a front guide ball, and a connecting line B, all of which are conductors. The connecting line B is electrically connected to the front guide ball.

[0006] Preferably, the left trimmer controls the lifting and lowering of the left side of the body, the right trimmer controls the lifting and lowering of the right side of the body, the front trimmer controls the lifting and lowering of the front end of the body, and the right trimmer and the left trimmer jointly control the lifting and lowering of the rear end of the body.

[0007] Preferably, the right trimmer, left trimmer, and front trimmer are at their shortest extension when the vehicle is towing, and automatically coordinate and trim when the vehicle is parked in the field.

[0008] Preferably, the right trimmer is rotatably connected to the right balancer, the left trimmer is rotatably connected to the rear left wheel, the right caliper is installed on the rear right wheel, and the left caliper is installed on the rear left wheel.

[0009] Preferably, the batteries are stacked in blocks and connected in parallel, and the number of stacked batteries can be freely selected according to user needs, with each block battery storing 50 kWh when fully charged.

[0010] Preferably, when the body is towed on a car, the front wheels are off the ground, and the rear left wheel can rotate freely.

[0011] Preferably, after the body separates from the car, the front wheels are in contact with the ground, while the rear left wheels cannot rotate.

[0012] The technical solution of this invention is as follows: A rear leveler and a front leveler are installed under the chassis of the RV. When the RV is used for off-roading and camping, and the angle between the RV chassis and the horizontal line is greater than α, the rear and front levelers activate the left, right, and front leveling devices, allowing the RV to be adjusted to a level state on surfaces that are either higher in the front and lower in the rear, or vice versa, or higher on the left and lower on the right, or vice versa. This provides a better user experience. Simultaneously, left and right calipers are provided. When the RV is detached from the vehicle, the mounting switch is activated, and the left and right calipers lock, preventing the RV from rolling even on a slope. This enhances the RV camping experience and improves safety. Attached Figure Description

The sphere (222) is connected in series, and the right balancer (110), left balancer (100) and front balancer (200) are connected in parallel. The central control system (5) includes a photovoltaic panel (3), an inverter (4), an electric vehicle charging output terminal (7), a motorhome in-vehicle power output terminal (6), and a battery (8). The central control system (5) is electrically connected to the motorhome balance system (9). The photovoltaic panel (3) is electrically connected to the central control system (5) through the inverter (4). The photovoltaic panel (3) and inverter (4) charge the battery (8) through the central control system (5).

The battery (8) supplies power to the RV's internal power output terminal (6) through the central control system (5) for powering the RV's internal electrical appliances. The mounting switch (201) is connected in series with the left caliper (202) and the right caliper (203) and is powered by the central control system (5).

[0031] Furthermore, the rear leveler (10) controls the left and right horizontal balance of the body (12), and the front leveler (20) controls the front and rear horizontal balance of the body (12). The rear leveler (10) includes a left guide block (1), a left guide block (11), a rear guide ball (111), and a connecting line A (101), all of which are conductors. The connecting line A (101) is electrically connected to the rear guide ball (111). The front leveler (20) includes a front guide block (2), a rear guide block (22), a front guide ball (222), and a connecting line B (102), all of which are conductors. The connecting line B (102) is electrically connected to the front guide ball (222).

[0032] Furthermore, the left trimmer (100) controls the left side of the body (12) to rise and fall, the right trimmer (110) controls the right side of the body (12) to rise and fall, the front trimmer (200) controls the front end of the body (12) to rise and fall, and the right trimmer (110) and the left trimmer (100) jointly control the rear end of the body (12) to rise and fall.

[0033] Furthermore, when the vehicle is towing, the right trimmer (110), left trimmer (100), and front trimmer (200) are at their shortest extension. When the vehicle body (12) is parked in the field, the right trimmer (110), left trimmer (100), and front trimmer (200) automatically coordinate and trim.

[0034] Furthermore, the right trimmer (110) is rotatably connected to the right balancer (303), the left trimmer (100) is rotatably connected to the rear left wheel (301), the right caliper (203) is mounted on the rear right wheel (302), and the left caliper (202) is mounted on the rear left wheel (301).

[0035] Furthermore, the batteries (8) are stacked in blocks and connected in parallel. The number of stacked batteries can be freely selected according to user needs, and each block battery can store 50 kWh of electricity when fully charged.

[0036] Furthermore, when the body (12) is towed on a car, the front wheel (303) leaves the ground, and the rear left wheel (301) and rear left wheel (302) can rotate freely.

[0037] Furthermore, after the body (12) is separated from the car, the front wheel (303) is in contact with the ground, while the rear left wheel (301) and rear left wheel (302) cannot rotate.

[0038] Example 2 like Figure 2 , 4 5, 8, 9, 10, 11. When facing various terrains, the left trimmer (100), right trimmer (110), and front trimmer (200) of this invention can automatically adjust on the ground after the RV is detached from the car and parked independently. The specific adjustment is as follows: When the RV is parked with the front higher than the rear, it needs to be stable because the front wheel (303), the rear left wheel (301), and the rear right wheel (302) need to touch the ground. To achieve horizontal balance, the rear right wheel (302) and the rear left wheel (301) need to be raised at the same time, while the front wheel (303) remains stationary. Because the front is higher than the rear, the rear guide block (22) in the front leveler (20) makes electrical contact with the front guide ball (222), and the right leveler (110) and the left leveler (100) are activated. At this time, the rear right wheel (302) and the rear left wheel (301) are raised until the angle between the RV and the horizontal is less than α, so that the RV can be parked smoothly on the ground.

[0039] When the RV is parked with the front lower than the rear, it needs to be stable because the front wheel (303), the left rear wheel (301), and the right rear wheel (302) need to touch the ground. To achieve horizontal balance, the front wheel (303) needs to be raised while the left rear wheel (301) and the right rear wheel (302) remain stationary. Because the front is lower than the rear, the guide ball (222) in the front leveler (20) makes electrical contact with the guide block (2), and the front leveler (200) is activated. At this time, the front wheel (303) is raised until the angle between the RV and the horizontal is less than α, so that the RV can be parked smoothly on the ground.

[0040] When the RV is parked with the left side lower than the right side relative to the ground, it needs to be stable because the front wheel (303), the rear left wheel (301), and the rear right wheel (302) need to touch the ground. To achieve horizontal balance, the front wheel (303) and the rear left wheel (301) need to be raised while the rear right wheel (302) remains stationary. Because the left side is lower than the right side, the front guide block (2) in the front leveler (20) makes electrical contact with the front guide ball (222), and the front leveler (200) is activated. At the same time, the left guide block (1) in the rear leveler makes electrical contact with the rear guide ball (111), and the left leveler (100) is activated. At this time, the front wheel (303) and the rear left wheel (301) are raised until the angle between the RV and the horizontal is less than α, so that the RV can be parked smoothly on the ground.

[0041] When the RV is parked with its left side suspended above the ground, it needs to be in contact with the ground at three points to be stable. In order for the RV to achieve horizontal balance, the left rear wheel (301) needs to be raised while the front wheel (303) and the right rear wheel (302) remain stationary. Since the left rear wheel (301) is suspended, the left guide block (1) in the rear leveler (10) makes electrical contact with the rear guide ball (111), and the left leveler (100) is activated. At this time, the left rear wheel (301) is raised until the angle between the RV and the horizontal is less than α, so that the RV can be parked smoothly on the ground. When the RV is parked with its right side suspended above the ground, it needs to be in contact with the ground at three points to be stable. In order for the RV to achieve horizontal balance, the rear right wheel (302) needs to be raised while the front wheel (303) and the rear left wheel (301) remain stationary. Since the rear right wheel (302) is suspended, the left guide block (1) in the rear leveler (10) makes electrical contact with the rear guide ball (111), and the right leveler (110) is activated. At this time, the rear right wheel (302) is raised until the angle between the RV and the horizontal is less than α, so that the RV can be parked smoothly on the ground.

[0042] In summary, although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
