DETAILED DESCRIPTION

[0023] The present invention is described in detail below with reference to the accompanying drawings.

[0024] As shown in the figure, a door leaf external hatch comprises a door frame 1 and a door leaf 2. The door frame 1 comprises a frame ring 11 which can be inserted into the door opening of the RV body 100. The outer end of the frame ring 11 extends to all sides to form a frame outer edge 111. The door leaf 2 comprises a door panel 21 and a door ring 22 fixed to the edge of the door panel. The door leaf 2 is arranged on the outside of the RV body 100 and does not enter the frame ring 11. The outer end of the door ring 22 buckles inward to form a door buckle edge 221, and the door buckle edge 221 completely covers the frame outer edge 111. Since the outer end of the door ring buckles inward to form the door buckle edge, the frame ring of the door frame is no longer directly exposed to the outside. The design of the door buckle edge makes the frame ring of the door frame completely hidden when the hatch door is closed, providing a neater and smoother appearance and enhancing the overall aesthetics of the RV. Since the door leaf does not need to enter the door frame or the door opening, the problem of the hatch door opening and closing being stuck caused by the sinking of the large-sized hatch door leaf due to its own gravity can be effectively avoided.

[0025] In another preferred embodiment, the inner end of the frame ring 11 forms a frame hook 112, and the frame glue strip 12 is clamped on the frame hook 112, and the frame glue strip 12 is tightly plugged to seal the door opening opened by the RV body 100. The frame glue strip 12 is tightly plugged in the door opening opened by the RV body 100, which can provide a better sealing effect and prevent the penetration of air and moisture. The elasticity of the glue strip can help absorb the impact force that may be generated by the door leaf in daily use, reduce damage to the door frame, and thus extend the service life of the cabin door. The design of the inner end of the frame hook 112 and the frame glue strip 12 makes the sealing component not exposed, which helps to maintain the neat appearance of the cabin door. Good sealing performance can also reduce the introduction of external noise and improve the comfort inside the RV. The sealing strip can effectively prevent dust, debris, etc. from entering the interior of the RV and keep the interior clean.

[0026] In another preferred embodiment, a plurality of mounting holes 113 are provided on the outer edge 111 of the frame ring 11, and the fastening screws are passed through the mounting holes 113 and screwed to the RV body 100 at the edge of the door opening. By evenly distributing the mounting holes 113 on the outer edge 111 of the frame, it is possible to ensure that the connection between the door frame 1 and the RV body 100 is more stable, and reduce shaking or abnormal noise caused by improper installation. The fastening screws are passed through the mounting holes 113 and screwed to the RV body 100 to form a solid connection to resist vibration and impact that may be encountered in daily use. The arrangement of the mounting holes 113 on the outer edge 111 of the frame can maintain the neat appearance of the door frame 1 without affecting the beauty of the door leaf 2.

[0027] In another preferred embodiment, the corner of the door ring 22 is recessed to form a door ring groove 222, and a door sealing strip 23 is embedded in the door ring groove 222. One end of the door sealing strip 23 is embedded in the door ring groove 222, and the inner surface of one end of the door sealing strip 23 is bonded to the door panel 21 through a self-adhesive layer. The embedding and bonding method of the door sealing strip 23 can provide a better sealing effect and effectively prevent air and moisture from entering the interior of the RV through the door gap. The use of the self-adhesive layer simplifies the installation process of the door sealing strip 23, without the need for additional fixings or complicated installation steps. The firm fixation of the door sealing strip 23 reduces the risk of the strip falling off during use and improves the safety of use. If the door sealing strip 23 needs to be replaced, due to its embedding and bonding fixing method, the disassembly and replacement work becomes relatively easy. A good sealing strip can not only be waterproof and dustproof, but also reduce noise when closing the door leaf, thereby improving the comfort inside the RV. The structure of the door ring embedding groove 222 helps to protect the rubber strip when the door leaf is subjected to external force and prevent it from deformation or displacement.

[0028] In another preferred embodiment, two twist-type door locks 3 are installed near the lower end of the door panel 21, the inner end of the twist-type door lock 3 is fixedly connected to the swing plate 31, the free end of the swing plate 31 is screwed with a screw 32, the nail head of the screw 32 abuts the frame ring 11 or the RV body 100, and the screw rod of the screw 32 is screwed with a back-tightening nut 33. The two twist-type door locks 3 provide a double locking mechanism, which increases the safety of the door leaf and makes it more difficult to be opened illegally. By setting the back-tightening nut 33, the tightening force of the screw 32 can be adjusted to adapt to RV bodies 100 of different thicknesses, ensuring the tightness and adaptability of the door lock. The design allows the door lock to adapt to RV bodies of different thicknesses, increasing the versatility of the door lock. The adjustment of the door lock is not limited by the thickness of the body, so that the same model of door lock can be adapted to RVs of different thicknesses, increasing the market competitiveness of the product.

[0029] In another preferred embodiment, a locking block 4 is provided on the frame ring 11 corresponding to the nail head of the screw 32, and one or more fixing holes 42 are provided on the upper end surface of the locking block 4. After the screw passes through the fixing hole 42 and the frame ring 11, it is screwed to the RV body 100. The upper end surface of the outer side of the fixing hole 42 is tilted downward to form a slope 41, and the nail head of the screw 32 abuts against the inner end surface of the locking block 4. The locking block 4 provides an additional fixing point, increases the stability of the door lock system, and prevents the door lock from loosening due to external force. The slope 41 of the locking block 4 is designed to serve as a guide surface when placing items, reduces the scratches on the edge of the lower frame, and protects the door frame from damage. The structure of the locking block 4 can disperse the force on the screw 32, reduce the direct pressure on the door frame 1, and thus improve the overall durability. The use of the locking block 4 and the screw 32 can reduce the noise generated by the door leaf during movement.

[0030] In another preferred embodiment, the upper ends of the door frame 1 and the door leaf 2 are respectively fixedly connected and hinged through a two-way pin hinge 5; an avoidance groove 223 is provided at the buckle edge 221 corresponding to the two-way pin hinge 5. The two-way pin hinge 5 increases the flexibility of opening and closing. The setting of the avoidance groove 223 provides the buckle edge 221 with necessary space to avoid interference with the door frame 1 when the door leaf 2 moves, which can reduce or eliminate the friction between the door leaf 2 and the door frame 1 during the opening and closing process, thereby reducing the noise generated during operation. The design of the avoidance groove 223 can be hidden in the buckle edge 221 without affecting the appearance of the door.

[0031] In another preferred embodiment, the outer contour of the door frame 1 and the door leaf 2 is in the shape of a rounded rectangle. The rounded rectangular design provides a more streamlined and modern appearance to the door leaf, and the rounded corner design is generally more in line with modern aesthetics than the traditional right-angled edges. Rounded corners can reduce sharp edges, thereby reducing the risk of injury caused by collisions, especially in RVs, which can provide additional safety for passengers. The rounded rectangular design may help to distribute forces more evenly in the structure of the door frame and door leaf, thereby improving overall durability and impact resistance. The rounded corner design is less likely to accumulate dust and dirt, which may reduce the workload of cleaning and maintenance. The rounded rectangular design may be easier to manufacture, especially when using certain materials such as plastics or certain metals, where the rounded edges are easier to form. Stress concentration is a common problem at the corners of the structure. The rounded corner design helps to disperse stress and reduce the risk of material fatigue and cracks. The rounded rectangular design may give people a more comfortable and friendly feeling, improving the overall user experience. The rounded rectangular door frame and door leaf can better match the decorative style of the interior of the RV, especially when the interior decoration adopts a streamlined or modern design.

Therefore, the utility model is not limited to the specific implementations disclosed and described above, and some modifications and changes to the utility model should also fall within the scope of protection of the claims of the utility model. In addition, although some specific terms are used in this specification, these terms are only for the convenience of description and do not constitute any limitation to the utility model.
