Description

Technical Field

[0001] This invention relates to the field of multi-functional vehicles, and more specifically to a multi-functional vehicle. Background Technology

[0002] Traditional RVs, as mobile living spaces, are facing the dual constraints of insufficient infrastructure and high operating costs. The sparse distribution of professional campsites and water and electricity supply stations leads to parking difficulties and low energy replenishment efficiency. The complex maintenance requirements of water and electricity systems and depreciation during idle periods make the overall cost significantly higher than that of ordinary passenger vehicles.

[0003] Therefore, family living vehicles based on ordinary passenger cars have emerged, transforming the interior space to have residential attributes. However, existing technologies still have obvious drawbacks: firstly, changing the vehicle's external parameters makes it difficult to meet road regulations; secondly, there is a structural contradiction in space utilization efficiency: when unfolded, the interior height of the living compartment is generally less than 2.1 meters due to the limited storage size, resulting in insufficient comfort for multiple users. Summary of the Invention

[0004] The present invention aims to provide a multi-functional vehicle that meets road regulations and provides sufficient comfort.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multi-functional vehicle, including a vehicle and a living compartment, the vehicle including a cargo box and a driver's cab, the living compartment being disposed on the cargo box, the living compartment being rotatably provided with a flip-top cover, the living compartment including a stowed state and an unfolded state;

[0006] In its stowed state, the flip-top covers the living quarters; in its unfolded state, the flip-top flips outwards to the top of the cockpit and rests on the cockpit.

[0007] The beneficial effects of this plan are:

[0008] 1. This invention combines a living compartment and a vehicle, and realizes the storage function of the living compartment through a flip cover and flip assembly. It can realize the living function of the RV, meet the appearance requirements of the vehicle on the road to ensure passability, comply with road regulations, and also remove the living compartment for cargo; the flip cover increases the net height of the activity range after flipping it over, ensuring the comfort of multiple users.

[0009] 2. Using the living compartment as the main base support, furniture and other facilities can be installed inside. To improve space utilization, the original space needs to be expanded. The flip-top component supports the flip-top cover of the living compartment after it is opened, thus forming the user's activity space. Compared with the traditional living compartment, this solution expands the user's activity space. By using the flip-top cover to build a new platform, the projected area of ​​the living compartment is increased, while maintaining the original footprint. It is suitable not only for installation on pickup trucks, but also for installation in campsites with limited ground space.

[0010] 3. Although this invention can be installed on a vehicle, its scope does not belong to traditional houses, traditional vehicles, or traditional RVs. It is a cross-border dwelling that integrates the vehicle with its environment. It is a highly integrated box-type equipment industrial product that can be expanded and changed. It is divided into pickup truck version and camping version. The pickup truck version is installed on the pickup truck bed (which can be quickly slid out of the vehicle body or loaded into the pickup truck bed); and the camping version is installed on various campsites (which can be quickly deployed on campsites and has lifting outriggers to support the cabin and a leisure platform).

[0011] Based on this product architecture, three campsite-type product lines and three pickup truck-type product lines can be defined.

[0012] Pickup truck series:

[0013] 1. Vehicle version: directly installed on the cargo box of a pickup truck. It belongs to the modification market. The pickup truck with the living compartment installed is still a vehicle model (the living compartment must be removed during the annual inspection). It is suitable for mobile small vendors and commercial pickup trucks for engineering operations (multi-purpose vehicle, home store and studio with scenery on the go).

[0014] 2. Passenger version: Equipped on the standard cargo box of a pickup truck and sold as a complete vehicle after being announced;

[0015] 3. Family Edition: An all-terrain multi-functional pickup SUV passenger vehicle designed and built on a Class II pickup chassis.

[0016] Camp Series Edition:

[0017] 1. Seasonal Version: Complementary to seasonal homestay campsite projects.

[0018] 2. Station Version: This version is designed to complement family-friendly travel stations and is suitable for families with children.

[0019] 3. Maker Edition: Comes with the Youth Maker Commune and is suitable for one or two people to use.

[0020] Furthermore, the space within the height range of the living quarters is divided into lower and middle levels, while the space above the plane where the living quarters' flip-top is located is the upper level.

[0021] The living quarters are symmetrically equipped with two sets of side extension components on the left and right sides. The side extension components are all located in the middle space. The side extension components include side flaps, side panels and two sets of folding panels. The folding panels include a first folding panel and a second folding panel that are hinged together. One side of the first folding panel is hinged to the side wall of the living quarters. The side panels are vertically arranged between the two second folding panels. The side flaps are hinged to the bottom of the living quarters. The side extension components have a non-extended state and an extended state.

[0022] In the non-extended state of the side extension assembly, the side flap folds inward into the living quarters, the first folding plate and the second folding plate overlap and turn into the living quarters, and the side plate serves as a side barrier structure for the living quarters.

[0023] When the side extension assembly is in the extended state, the first folding plate and the second folding plate unfold to an angle greater than 90°. The second folding plate pushes the side plate away from the living quarters, and the side flap flips outward to the side of the living quarters.

[0024] Furthermore, the middle space includes a middle side extension space, which is formed by a side panel, a side flap, a first folding panel, and a second folding panel.

[0025] The tarpaulin includes a canopy, with air columns supporting the middle of the canopy. The two sides of the canopy are inclined downwards to form an inclined tarpaulin. The lower edge of the inclined tarpaulin is connected to the upper part of the side plate. The triangular area between the middle-layer side expansion space and the inclined tarpaulin forms the upper-layer side expansion area.

[0026] Furthermore, a rear extension assembly is provided on the rear side of the living quarters. The rear extension assembly includes a sliding plate, which is located in the lower space. The sliding plate and the living quarters are horizontally slidably connected. The rear extension assembly also includes a non-extended state and an extended state.

[0027] When the rear extension assembly is not extended, the skateboard slides into the living compartment.

[0028] With the rear extension component extended, the skateboard partially slides out of the living compartment.

[0029] Furthermore, the skateboard has a support plate that slides horizontally on its side.

[0030] Furthermore, the rear extension component includes a tailgate located in the middle space, behind the living quarters. The tailgate opens horizontally outwards and has a fold-down cover. The tailgate has storage space inside, and the cover folds down to access the lower space.

[0031] Furthermore, the rear extension assembly includes a top cover, a first upright and a second upright, the lower end of the first upright is connected to the living compartment, the lower end of the second upright is hinged to the upper end of the first upright, the second upright is hinged to the top cover, and the edge of the top cover is provided with a drooping flexible partition.

[0032] In the non-extended state of the rear extension component, the top cover rotates to be in contact with the second upright, and the second upright rotates to be in contact with the first upright. Both the top cover and the second upright are located below the upper space.

[0033] In the extended state of the rear extension component, the second upright rotates to be collinear with the first upright, the top cover rotates to be horizontal, and the tops of both the top cover and the second upright enter the upper space.

[0034] Furthermore, the air column includes an oblique support and several vertical supports, all of which are located inside the living compartment. The lower ends of the oblique supports are connected to the lower parts of the vertical supports. The oblique supports are located above the flip-top cover in the unfolded state. Tensile supports are provided between the upper sides of the vertical supports and the upper sides of the oblique supports.

[0035] Furthermore, the cargo box is equipped with sliding rails, and the living compartment has a sliding groove on the lower side, with the sliding rails and the sliding groove sliding together.

[0036] Furthermore, an electromagnetic locking device is provided between the slide rail and the slide groove. When energized, the electromagnetic locking device opens; when de-energized, the electromagnetic locking device locks the slide rail and the slide groove.

[0037] This solution also has the following effects:

[0038] 1. After the flip cover is opened, it is supported by an electric push rod; when switching to the storage state, the electric push rod extends, thereby driving the flip table to flip inward. Then the electric push rod and the flip cover are separated to facilitate the retraction of the electric push rod.

[0039] 2. The side extension components are used to extend the middle space of the living cabin on both sides, and together with the tarpaulin, extend the upper space on both sides, thus forming a trapezoidal side extension space. Compared with only extending the middle space, this solution extends the upper space simply by tilting the tarpaulin on both sides, so that people have enough height when lying in the side extension space without feeling cramped, thus increasing the comfort of living.

[0040] 3. The rear extension assembly is used to expand the rear space of the living quarters to form a shower room for showering and to serve as the entrance and exit of the living quarters; the sliding plate has a drain outlet to facilitate the flow of shower water; the tail door is a double door, and the rear flap, tail door and tail door cover form the enclosure of the shower room; the top cover has an exhaust system to remove the heat generated during showering, and a flexible partition is used to protect the privacy of the shower user.

[0041] 4. The middle part of the tarpaulin is connected to the upper end of the vertical support, the front side of the tarpaulin is connected to the upper end of the diagonal support, and the left and right edges of the tarpaulin are connected to the upper side of the side plate.

[0042] When assembling a multi-functional vehicle according to the present invention, the flip cover needs to be opened first, that is, the flip cover is flipped outward to the top of the driver's cabin. Then, the side extension component is switched to the extension state, and finally the vertical support is inflated.

[0043] During inflation, because the vertical supports are set vertically, and the gas must first enter the bottom of the vertical supports and then enter the diagonal supports at an angle, the vertical supports are inflated before the diagonal supports, thus supporting the top and sides of the tarpaulin first, and then the diagonal supports support the front of the tarpaulin.

[0044] Compared to supporting the entire tent fabric simultaneously, which tightens both sides and the front at the same time, the method of setting up the tent is more susceptible to the effects of the tent's folded-up state. If the tent unfolds slowly due to partial jamming, it can generate significant tension, reducing the tent's durability. In this solution, after the vertical support is completed and inflation is finished, the sides of the tent are opened first. Even if the tent is slightly jammed at this point, the front of the tent can be pulled to prevent the sides from becoming too tight, thus providing some cushioning to the front of the tent. Finally, the front of the tent is tightened to complete the tent setup.

[0045] 5. If the vertical support is inflated before the flip cover is fully opened due to accidental contact or other reasons, the inclined support in this solution can push the flip cover open at a more angle, making it easier and faster to open the flip cover than the vertical support. This avoids economic losses caused by collisions between the tarpaulin and furniture inside the living cabin when the tarpaulin is opened.

[0046] 6. This invention can be used alone outdoors or installed on a pickup truck.

[0047] 7. This plan takes into account both sunny and rainy weather, adopting an open-air design for the living cabins, with an open top, which also eliminates the step of building a roof, and directly uses a tent instead of a roof; the tent's air column inflates to support the tarpaulin, which is convenient and quick, and only one inflation device is needed to quickly complete the roof construction.
