Description

TECHNICAL FIELD

[0001] The present invention relates to the field of recreational vehicles, and in particular to a prefabricated mobile cabin with integrated lifting device. BACKGROUND

[0002] Most B-type recreational vehicles are manufactured by permanently modifying a van chassis - removing the original interior structure of the cargo compartment and installing fixed living facilities such as beds, seats, small kitchens and piping. While this method makes full use of the space, it often renders the van unable to carry cargo as originally intended and usually requires reclassification as a recreational vehicle. Once modified, it can be difficult, expensive and time-consuming to restore the vehicle to its original cargo-carrying form.

[0003] The same limitations apply to other special-purpose vehicles such as pet grooming vehicles, mobile service vehicles or mobile offices. Once customized for a specific purpose, these vehicles can only be used for a single purpose, have limited flexibility and reduced resale value.

[0004] Our invention solves these problems by abandoning the traditional, customized permanent equipment configuration approach and developing a fully prefabricated modular box containing all the necessary facilities ready for immediate use, equipped with an integrated lifting system and removable pulleys for easy adjustment to match the height of the cargo compartment, as well as telescopic support arms and a ground rail system for alignment and guidance of the box into the cargo compartment or trailer without the need for external equipment. SUMMARY

[0033] The working principle of the above technical scheme is as follows:

[0034] The four corners of the box 1 in the device are provided with manual or electric lifting support legs 5, and are provided with detachable and locking rotary pulleys 4 to ensure stability and mobility. The locking rotary pulleys 4 are detachably installed on the electric lifting support legs 5 through the locking buckle 8, and the flexibility of the device is improved. Two telescopic front support arms 6 are provided with guide wheels 7 which are matched with pre-installed floor tracks to realize accurate loading and unloading direction guidance. The auxiliary pulley 14 installed at the bottom of the box can realize movement even when the support legs are retracted. During installation, the electric lifting support legs 5 adjust the box to match the height of the vehicle floor, then the box is transported into the vehicle compartment through the guide wheels 7 and the front support arms 6, and is fixed by a rope. The device is suitable for closed and open trailers. In a stationary state, the device can be lowered to enhance stability, or rolled through the auxiliary pulley 14 at the bottom. Three cabins can be expanded through a cross telescopic structure to improve the space of the device. The box 1 can be pre-set with multiple expandable cabins. Each cabin can be detachably connected through screws, bolts or sliding rails, which is convenient for prefabrication, modification and maintenance according to different purposes. The lifting system and circuit, and the waterway system are provided with maintenance doors which are detachable through screws for system maintenance. The internal cabinets, sofas, beds, tables and other household components can also be detached through corner codes and screws. The modular, detachable and easy-to-maintain integrated design makes the modification and maintenance of the box easy to some extent.

[0035] The specific method of installing on the vehicle is as follows: install guide rails on the vehicle compartment floor or trailer floor, install wheels at the bottom of the box lifting legs, move to the corresponding position, raise the electric lifting support legs to a position higher than the vehicle compartment level, extend the two front support arms to the vehicle, adjust the height of the electric lifting support legs, lower the front support arms to the vehicle floor, push into the vehicle, retract the front two lifting legs, completely retract, hang, detach the wheels at the bottom of the electric lifting support legs through the bolt and replace them with support bases, fix the support bases with the bolt, continue to push, retract the rear two electric lifting support legs, also completely retract and hang, replace the wheels with support bases, and after pushing to the position, lower the four support bases to the floor. Pass the rope through the rope rings on the front and rear sides of the box, and fix it in the vehicle compartment.

[0036] The device has a modular internal layout, and can be equipped with multiple, for example, three convertible sliding modules, each of which is designed for a specific function, such as camper, mobile office, commercial use.

[0037] Meanwhile, the expandable roof 2 at the top of the device is equipped with waterproof canvas and a lifting system assisted by hydraulic rods and cross structures for quick deployment. The two side expansion cabins are provided with cross telescopic design and are detachable from the box through screws, which facilitates quick deployment, disassembly, modification and maintenance.

[0038] The device does not require permanent installation on a vehicle. In addition to being mounted on a van or trailer, it can also function as a completely independent living space. Vehicle ownership is not required; customers can rent or borrow vehicles. The device can also be used as a mobile micro-home for full-time or long-term residence and can be used like a portable micro-home, providing flexibility for customers who want to live off-grid or nomadic lifestyles, not just for short-term camping. The device can also be used for mobile business activities or service personnel, with different layouts (such as equipped with a workbench, sink, and storage space). If a customer's vehicle breaks down or is replaced, the device can be easily removed from the original vehicle and reinstalled on another vehicle, unlike traditional permanent van conversions.

[0039] The product is small enough to be stored in a standard family garage when not in use; it can be used not only in vans, but also in trailers or flatbeds, or even placed on the ground for stationary use.

[0040] The above embodiments merely illustrate specific implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
