Description

Technical Field

[0001] This utility model relates to the field of automotive technology, specifically to a rear flip-up door and rear cover structure and the vehicle thereof. Background Technology

[0002] Currently, many recreational vehicles or campervans on the market that are modified from pickup truck chassis either have doors on the side or at the rear. In order to ensure that the height of the doors meets the standard requirements, the overall height of the vehicle is made relatively high, which affects the vehicle's handling performance and passability.

[0003] This design has obvious shortcomings: First, the high overall vehicle height affects the vehicle's handling performance and passability; second, in terms of space utilization and functional adaptation, there is a lack of effective structural design to create a flexible and interconnected yet separable living and resting space between the tent and the rear cover, which cannot well meet the user's space needs during use. Utility Model Content

[0004] The purpose of this utility model is to provide a rear flip-up door, a rear cover structure and the vehicle thereof, which has the advantages of reducing the overall vehicle height to improve handling and passability, while realizing flexible interconnection and separation between the tent and the rear cover space, optimizing space utilization, and solving the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A rear-mounted flip-up door and rear cover structure includes a rear frame, a door mechanism at the rear of the rear frame, and a stop block fixed to one side of the rear frame. The door mechanism includes a flip-up door and a cargo box tailgate. The flip-up door is connected to the rear top of the rear frame via a hinge, and the cargo box tailgate is connected to the lower rear of the rear frame via a hinge. The flip-up door and the cargo box tailgate form a double-door structure, and both can be opened individually or simultaneously. When the flip-up door and the cargo box tailgate are closed simultaneously, they are locked together by a locking mechanism.

[0007] Preferably, the upward-opening door is provided with support members on both sides, and the support members are gas springs or electric push rods, which are used to drive or assist the upward-opening door to open automatically.

[0008] It is worth noting that by using gas springs or electric push rods as support components, the automatic upward opening of the lift-up door can be easily achieved without the need for manual lifting, which reduces the difficulty of operation and improves the convenience of use. At the same time, the support components can stably support the lift-up door after it is opened, preventing it from falling accidentally and ensuring safety during use.

[0009] Preferably, the upper door is provided with shielding components on both sides that open synchronously with its opening. The shielding components are fan-shaped baffles. When the upper door is opened, the fan-shaped baffles form side shields and together with the side frames of the vehicle, the upper door and the bottom of the cargo box of the rear frame, form an overall doorway.

[0010] It is worth noting that the fan-shaped baffle opens simultaneously with the flip-up door to form a side shield, which can effectively prevent wind, rain, dust and other external elements from entering the vehicle, improving the comfort of the environment when using the doorway. At the same time, the overall doorway formed by the baffle and other components ensures the integrity of the doorway and provides a more orderly space for people to enter and exit and for goods to be moved.

[0011] Preferably, a sealing element is provided between the upward-opening door and the door frame of the corresponding rear frame. The sealing element is a sealing strip, which is used to achieve a sealed fit between the two.

[0012] It is worth noting that the sealing strip can effectively fill the gap between the lift-up door and the door frame, enhancing the sealing between the two and preventing rainwater, dust and other substances from seeping into the car from the gap, keeping the car interior clean and dry. In addition, it can also reduce the friction and collision between the door and the door frame during vehicle operation, reduce noise and improve the quietness of the ride.

[0013] Preferably, it also includes a rear cover mounted on the rear frame, the front of which has a recessed platform for placing a tent, and when the tent is closed, its upper surface is flush with the upper surface of the rear cover.

[0014] It is worth noting that the platform provides a dedicated space for the tent, ensuring the stability and neatness of the tent installation. When the tent is closed, it is flush with the rear cover, making the rear of the vehicle look flatter and more aesthetically pleasing. At the same time, it avoids the tent protruding and increasing wind resistance during driving, which helps to reduce energy consumption.

[0015] Preferably, the tent can be opened to the side of the vehicle. The bottom plate of the tent located in the rear cover section is provided with a partition structure of hinged baffle or pull-out partition. The partition structure can be flipped / moved by manual or electric drive. The partition structure is used to enable communication or separation between the tent and the space under the rear cover. When the tent is opened to the side of the vehicle, flipping or moving the bottom plate can enable communication between the tent and the space under the rear cover. Flipping or closing the bottom plate can separate the tent from the lower part of the rear cover, forming a complete resting space.

[0016] It is worth noting that the tent opens to the side for easy operation and entry / exit. The partition structure design allows for flexible switching between the tent and the space under the rear cover. When connected, the space can be integrated to form a larger living area to meet daily activity needs. When partitioned, it can form an independent resting space, ensuring privacy and a quiet environment for rest, and improving the flexibility of space utilization.

[0017] Preferably, the rear frame has a platform on top of the cab, a fairing at the front end of the platform, and the platform can communicate with the tent at the rear of the vehicle.

[0018] It is worth noting that the cab roof platform has multiple functions. The front fairing can optimize airflow during vehicle operation, reduce wind resistance, and improve fuel economy. The platform can be used to place luggage, increasing storage space, and can also be used as a viewing platform. Interconnection with tents further expands the activity space, providing users with more usage scenarios and improving the practicality of the vehicle.

[0019] Preferably, the locking mechanism is an electromagnetic lock, which includes an electromagnetic coil and a latch that works with it. When the electromagnetic coil is energized, it generates a magnetic force to attract the latch, thereby locking the top-opening door and the cargo box tail door.

[0020] It is worth noting that electromagnetic locks achieve locking through electromagnetic force, are easy to operate, respond quickly, and have a stable and reliable locking state. They can effectively ensure the tightness and security of the top-opening door and the tailgate of the cargo box after they are closed. At the same time, they facilitate automated control and improve the intelligence level of the vehicle.

[0021] Preferably, the locking mechanism is a latch lock, which includes a latch plate and a latching slot that cooperate with each other. The latch plate is provided on one of the top-opening door or the rear door of the cargo box, and the latching slot is provided on the other door. When both are closed, the latch plate engages with the latching slot to achieve locking.

[0022] It is worth noting that the plate lock has a simple structure, is sturdy and durable, has low manufacturing cost, and is easy to maintain. It achieves locking through the mechanical cooperation of the plate and the slot, and the locking effect is stable. It can effectively prevent the door from being accidentally opened while the vehicle is in motion or parked, thus ensuring the safety of the vehicle.

[0023] This utility model also provides a vehicle, which includes a rear flip-up door and a rear cover structure as described above, and also includes ventilation openings on both sides of the rear frame, with automotive ventilation windows provided on the inner walls of the ventilation openings.

[0024] It is worth noting that air vents and car windows can promote air circulation inside the car, promptly remove odors and moisture, keep the air inside the car fresh, and achieve natural ventilation in suitable weather conditions, reducing the use of air conditioning and helping to save energy. At the same time, ventilation windows can also play a certain role in preventing dust and insects during ventilation, improving the comfort of the car's interior environment.

[0025] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0026] 1. This utility model effectively solves the problem of excessive vehicle height caused by ensuring the height of the door in existing pickup truck converted into motorhomes by setting up an upper and lower double door structure consisting of an upper door and a cargo box tail door. The upper door is connected to the top rear of the rear frame by a hinge, and the cargo box tail door is connected to the lower rear of the rear frame. The upper and lower double door structure formed by the two can meet the door opening height requirements without raising the overall vehicle height, lowering the vehicle's center of gravity, improving the vehicle's handling performance and passability, and enabling it to adapt to more road conditions, including smoothly entering height-restricted areas such as underground parking garages;

[0027] 2. In terms of space utilization and functional adaptation, this utility model solves the problem of lack of flexible communication and separation between the tent and the rear cover space through the synergistic effect of multiple structures: the recessed platform at the front of the rear cover provides a stable space for the tent to be placed. When the tent is closed, it is flush with the rear cover, ensuring a neat appearance and low wind resistance. When the tent is opened to the side, the flip-out or movable partition structure of its bottom plate comes into play. When the bottom plate is flipped or moved, the space under the tent and the rear cover is interconnected, forming a larger living area to meet the needs of daily activities. When the bottom plate is flipped or closed, the two are separated to form an independent resting space, ensuring privacy and a quiet environment. At the same time, the space between the top platform of the cab and the tent is interconnected, further expanding the activity space and improving the space utilization rate.

[0028] 3. The support components (gas springs or electric push rods) on both sides of the flip-up door assist the door to open automatically. The fan-shaped baffle forms a side shield and surrounds the entire doorway as the door opens. The sealing strip enhances the sealing performance. The locking mechanism (electromagnetic lock or plate lock) ensures that the door is closed securely. The ventilation openings and ventilation windows on both sides of the rear frame promote air circulation. These structures together improve the vehicle's ease of use, safety and comfort, and comprehensively optimize the performance of the pickup truck converted into a motorhome.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Throughout the century-long history of the automotive industry, the design of vehicle rear structures has consistently evolved around practicality, safety, and aerodynamic performance. Among these, the combination of a liftgate and rear cover has become a signature design element for many vehicle models due to its unique functionality. This structure is widely used in SUVs, MPVs, hatchback sedans, and some commercial vehicles. Its core lies in achieving a balance between space utilization and ease of operation through an integrated liftgate and rear cover.

[0035] The rear liftgate, often referred to in the industry as the "back door," is a crucial component connecting the top and rear of the vehicle. Its main structure consists of a high-strength steel frame and an outer covering. The frame is assembled using laser welding technology to ensure structural stability during frequent opening and closing. The covering is mostly made of aluminum alloy or composite resin materials, reducing weight and improving corrosion resistance. The door is connected to the vehicle body using two sets of heavy-duty hinges. The hinge bushings use self-lubricating bearings, capable of withstanding tens of thousands of opening and closing cycles while maintaining a smooth feel. Some high-end models also integrate a gas spring support system in the hinges, using air pressure damping to control the door's opening speed, preventing sudden drops due to gravity, and providing cushioning assistance when closing.

[0036] As a crucial component of the tailgate, the rear cover serves multiple functions, including sealing, protection, and aesthetics. Its inner side is fitted with multi-layered sealing strips made of EPDM (ethylene propylene diene monomer) rubber, which maintains elasticity within a temperature range of -40℃ to 80℃, effectively blocking rainwater, dust, and noise. The cover surface is typically painted the same color as the vehicle body, with robotic painting ensuring color difference is controlled within the industry standard of ΔE≤1.5. On some models, the rear cover also integrates pre-drilled holes for a high-mounted brake light, rear wiper, and camera. The high-mounted brake light uses LED light sources, with a response time 0.3 seconds faster than traditional halogen lights, reducing the risk of rear-end collisions.

[0037] The core advantage of this combined structure lies in its efficient space utilization. When the tailgate is fully open, the opening angle can reach 75°-90°, and combined with the low sill design (typically ≤700mm from the ground), it creates a spacious loading passage. Taking a typical SUV as an example, the standard trunk volume is approximately 500L, which can be expanded to over 1500L after folding down the rear seats, with an internal space flatness error of ≤5mm, facilitating the placement of large items. In addition, the tailgate opening height can be adjusted according to user needs, achieving precise positioning through a motor memory function to meet the operational needs of users of different heights.

[0038] In terms of vehicle applications, the liftgate and rear hatch structure is most common in SUV models. Taking the Toyota Prado as an example, its tailgate features a side-opening liftgate design, combined with the robust lines of the rear hatch, showcasing a rugged off-road style while ensuring the practicality of the trunk. In the urban SUV segment, the Honda CR-V uses a power liftgate, with the rear hatch integrated with the taillights, enhancing the overall refinement of the vehicle. In MPV models, the Buick GL8's liftgate is equipped with a hands-free opening function; users simply need to slide their foot under the rear bumper to trigger the motor and open the tailgate, greatly improving ease of use.

[0039] Besides passenger cars, some commercial vehicles also adopt this structure. For example, the tailgate design of the Jiangling Ford Transit caters to both passenger and cargo needs, with an upward tilt angle of up to 180°. Combined with foldable rear seats, it allows for flexible changes in the interior space layout. In the field of new energy vehicles, the Tesla Model Y's tailgate features a frameless design, with a smooth transition between the rear cover and the roofline, effectively reducing the drag coefficient and improving range.

[0040] It's worth noting that with the development of automotive intelligence, the structure of the tailgate and rear cover is also constantly being upgraded. Currently, some models are equipped with an anti-pinch tailgate function, which uses infrared sensors to detect obstacles and automatically reverses the opening when resistance is encountered during the closing process, preventing injury to users or damage to items. Meanwhile, the application of vehicle networking technology allows the tailgate to be remotely controlled via a mobile app, enabling users to open the tailgate in advance after shopping without having to approach the vehicle, facilitating loading of items.

[0041] In terms of safety, this structure has also been comprehensively optimized. The reinforcing ribs inside the tailgate are made of high-strength hot-formed steel, which can effectively absorb collision energy in the event of a rear-end collision, protecting the safety of the occupants. The reflective strips on the rear cover surface, together with the high-mounted brake light, improve the vehicle's visibility at night or in inclement weather, reducing the risk of traffic accidents.

[0042] Applying the design concept of a rear liftgate and rear cover structure to motorhomes or campervans converted from pickup truck chassis can effectively solve their existing problems. The hinge structure of the rear liftgate can be improved by using an adjustable, multi-stage hinge. While ensuring the door opening height meets standards, optimizing the hinge installation position reduces the door's dependence on the overall vehicle height. For example, the hinge fixing point can be appropriately lowered, combined with lightweight carbon fiber overlays, reducing the door's own weight's restriction on the installation position, thus avoiding blindly increasing the overall vehicle height to meet door height requirements.

[0043] For the rear cover, a modular design can be adopted, integrating some functional components inside the cover to reduce the space occupied at the rear and thus lower the overall vehicle height. Simultaneously, utilizing the elasticity of the sealing strips, the gap between the cover and the body can be reduced while ensuring sealing performance, further controlling the height. Furthermore, borrowing the motor memory function for the tailgate opening height from SUV models, the rear liftgate of motorhomes or campervans can also adjust its opening height according to actual usage scenarios. This meets the needs of different situations without increasing the overall vehicle height due to a fixed high opening height, thereby improving vehicle handling and off-road capability.

[0044] To address the issues in existing technologies where converting pickup trucks into motorhomes or campervans results in excessive vehicle height due to door height requirements, affecting handling and passability, and where the tent and rear cover lack flexible interconnection and partition structures, leading to poor space utilization, the following technical solutions are proposed. Please refer to [link / reference]. Figures 1-3 ;

[0045] A rear-mounted flip-up door and rear cover structure includes a rear frame 1. The rear of the rear frame 1 is provided with a door mechanism 2. A stop block 3 is fixedly connected to one side of the rear frame 1. The door mechanism 2 includes a flip-up door 201 and a cargo box tail door 202. The flip-up door 201 is connected to the top rear of the rear frame 1 by a hinge, and the cargo box tail door 202 is connected to the lower rear of the rear frame 1 by a hinge. The flip-up door 201 and the cargo box tail door 202 form a double-door structure, and the two can be opened individually or simultaneously. When the flip-up door 201 and the cargo box tail door 202 are closed at the same time, they are locked to each other by a locking mechanism.

[0046] In this embodiment, specifically, the upward-opening door 201 is provided with support members on both sides. The support members are gas springs or electric push rods, which are used to drive or assist the upward-opening door 201 to automatically open upwards.

[0047] In this embodiment, specifically, the upper door 201 is provided with shielding components on both sides that open synchronously with its opening. The shielding components are fan-shaped baffles 4. When the upper door 201 is opened, the fan-shaped baffles 4 form side shielding and together with the side frames 5 of the vehicle, the upper door 201 and the bottom of the cargo box of the rear frame 1, they enclose the overall door opening.

[0048] In this embodiment, specifically, a sealing element is provided between the upward-opening door 201 and the door frame of the corresponding rear frame 1. The sealing element is a sealing strip 6, which is used to achieve a sealed fit between the two.

[0049] In this embodiment, specifically, it also includes a rear cover 9 disposed on the rear frame 1. The front of the rear cover 9 is provided with a recessed platform 7, which is used to place the tent 8. When the tent 8 is closed, its upper surface is flush with the upper surface of the rear cover 9.

[0050] In this embodiment, specifically, the tent 8 can be opened to the side of the vehicle. The bottom plate of the tent 8 located in the rear cover 9 is provided with a partition structure of hinged baffle or pull-out partition. The partition structure can be flipped / moved by manual or electric drive. The partition structure is used to realize the interconnection or separation between the tent 8 and the space below the rear cover 9.

[0051] When the tent 8 is opened to the side of the vehicle, the space under the tent 8 and the rear cover 9 can be connected by flipping or moving the bottom plate.

[0052] By flipping over or covering the bottom plate, the tent 8 can be separated from the lower part of the rear cover 9, forming a complete resting space.

[0053] It should be noted that the operation procedure for the partition structure is as follows:

[0054] Manual operation: After the tent 8 is opened to the side, the user can manually flip the hinged baffle (or horizontal pull-out partition) by using the handle or pull ring to make the space under the tent and the rear cover open.

[0055] Electric operation: The partition structure can be connected to a micro motor, and the baffle can be automatically flipped or the partition can be electrically slid by the in-vehicle button or remote control, so as to realize one-button interconnection or separation.

[0056] In this embodiment, specifically, a platform 10 is provided on the top of the cab of the rear frame 1, a fairing 11 is provided at the front end of the platform 10, and the platform 10 can communicate with the tent 8 at the rear of the vehicle.

[0057] Example 1: In this example, the locking mechanism is an electromagnetic lock, which includes an electromagnetic coil and a latch that works with it. When the electromagnetic coil is energized, it generates a magnetic force to attract the latch, thereby locking the lift-up door 201 and the cargo box tail door 202.

[0058] The electromagnetic lock is easy to operate and responds quickly. The locking state achieved by electromagnetic force is stable and reliable, which can effectively ensure the tightness and security of the top door 201 and the cargo box tail door 202 after they are closed. At the same time, it is easy to realize automated control and improve the intelligence level of the vehicle.

[0059] Example 2: In this example, the locking mechanism is a latch lock, which includes a latch plate and a latch slot that cooperate with each other. The latch plate is set on one of the top-opening door 201 or the cargo box tail door 202, and the latch slot is set on the other door. When both are closed, the latch plate engages with the latch slot to achieve locking.

[0060] The plate lock has a simple, robust and durable structure, low manufacturing cost, and is easy to maintain. Through the mechanical cooperation of the plate and the slot, it can stably lock the top door 201 and the cargo box tail door 202, effectively preventing the doors from being opened accidentally and ensuring the safety of the vehicle when driving and parking.

[0061] This utility model also provides a vehicle, which includes a rear flip-up door and a rear cover structure as described above, and also includes ventilation openings on both sides of the rear frame 1, with automotive ventilation windows provided on the inner walls of the ventilation openings.

[0062] Ventilation vents and car ventilation windows promote air circulation within the rear frame 1, promptly expelling odors and moisture and keeping the air inside the vehicle fresh. In suitable weather, natural ventilation can be achieved, reducing the use of air conditioning to save energy. At the same time, ventilation windows can also prevent dust and insects, improving the comfort of the in-vehicle environment.

[0063] Working principle: When the rear flip-up door and rear cover structure and the vehicle are in use, the door mechanism 2 at the rear of the rear frame 1 can be opened individually or simultaneously by the flip-up door 201 and the cargo box tail door 202 to meet the usage needs of different scenarios.

[0064] When the lift-up door 201 is opened, the support members (gas springs or electric push rods) on both sides drive or assist the lift-up door 201 to automatically lift up. At the same time, the fan-shaped baffle 4, which opens synchronously with the lift-up door 201, forms a side shield and together with the side frames 5 of the vehicle, the lift-up door 201 and the bottom of the cargo box of the rear frame 1, forms an overall door opening. The sealing strip 6 between the lift-up door 201 and the door frame of the rear frame 1 ensures a sealed fit when the two are closed.

[0065] The tailgate 202 can be opened independently. When the lift-up door 201 and the tailgate 202 are closed at the same time, they are locked to each other by a locking mechanism (electromagnetic lock or plate lock). The electromagnetic lock is locked by generating magnetic force to attract the latch through the electromagnetic coil being energized. The plate lock is locked by the plate being inserted into the slot.

[0066] The recessed platform 7 at the front of the rear cover 9 is used to place the tent 8. When the tent 8 is closed, its upper surface is flush with the upper surface of the rear cover 9. After the tent 8 is opened to the side of the vehicle, the partition structure on the bottom plate of the rear cover 9 can be flipped or moved to achieve communication between the tent 8 and the space under the rear cover 9. Flipping or covering the bottom plate will separate the two to form a complete resting space.

[0067] The air deflector 11 at the front of the platform 10 on the top of the cab of the rear frame 1 optimizes airflow, and the platform 10 can communicate with the tent 8. The ventilation openings on both sides of the rear frame 1 and the car ventilation windows on the inner wall promote air circulation and ensure a comfortable environment inside the vehicle.
