Description

Technical Field

[0001] This utility model relates to the field of RV accessories, specifically to a waterproof RV cabin door. Background Technology

[0002] In RV design, the door area serves as a crucial link between the interior living space and the external environment, making its functional integration paramount. To enhance convenience and space utilization, modern RVs often incorporate integrated small trash can mounting points or storage compartments on the inside or outside of the door. This design aims to allow occupants to quickly dispose of small trash items or access frequently used small items without having to enter the main living area or open large storage compartments.

[0003] Chinese utility model patent application number CN201720439730 discloses a RV storage compartment door, which relates to the field of door technology. It includes a door frame, a door leaf hinged to the door frame, a door lock fixed to the door leaf, and a lock block fixed to the door frame. The door lock includes a lock tongue that is rotatably connected to the door leaf. The edge of the door frame is provided with a sealing strip for improving sealing. When the door leaf is closed, the lock tongue is located on the side of the lock block away from the door leaf.

[0004] Based on the aforementioned prior art, the inventors believe that, due to the possible gaps between the door frame and the door leaf, the RV will be continuously exposed to the changing external environment while in motion. During long-term driving, the sealing strip may loosen, allowing external moisture to enter the cabin through the gaps, causing the items inside the cabin to become moldy. Utility Model Content

[0005] The present invention aims to solve the aforementioned existing problems by providing a waterproof RV door that can prevent external moisture from entering the door through gaps.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following solution: a waterproof RV door, including a bottom shell, a frame installed on the bottom shell, and a cover plate covering the frame. The frame is provided with an annular receiving groove, and a sealing strip is provided between the frame and the cover plate. The sealing strip is annularly arranged in the receiving groove. The cover plate is provided with an outwardly protruding part that is arranged opposite to the sealing strip. The protruding part presses against the sealing strip, causing the sealing strip to deform towards the receiving groove and make tight contact with the inner wall of the receiving groove.

[0007] This application features an annular receiving groove on the frame, allowing the sealing strip to be placed in a ring shape within the groove. A protrusion opposite to the sealing strip is provided on the cover plate. The protrusion presses against the sealing strip, causing it to be squeezed into the receiving groove. This deforms the sealing strip into the receiving groove and makes it tightly contact the inner wall of the groove, ultimately achieving a complete seal between the frame and the cover plate. This prevents external moisture from entering the hatch through the gap and improves the hatch's waterproof performance.

[0008] Preferably, a deformation cavity is provided at the center of the inner side of the sealing strip to expand the deformation space of the sealing strip. The deformation cavity at the center of the inner side of the sealing strip can effectively expand the deformation space of the sealing strip, ensuring that the sealing strip can deform more flexibly when subjected to external force, thereby enhancing the sealing effect.

[0009] Preferably, the sealing strip includes a connecting and fixing portion with its lower end equal in width to the receiving groove, and a contact deformation portion with its upper end for contacting the protrusion and having a deformation space between it and the inner wall of the receiving groove. The connecting and fixing portion, being equal in width to the receiving groove, stabilizes the sealing strip and prevents it from shifting within the receiving groove. The contact deformation portion contacts the protrusion of the cover plate. As the cover plate gradually closes onto the frame, the protrusion contacts the contact deformation portion, causing it to deform. The contact deformation portion deforms into the deformation cavity and expands towards both sides of the inner wall of the receiving groove, ensuring tight contact between the contact deformation portion and the inner wall of the receiving groove, further improving the sealing performance.

[0010] Preferably, the side of the sealing strip that contacts the protrusion protrudes outward from the receiving groove. This protrusion ensures that the sealing strip extends beyond the edge of the receiving groove even when compressed, resulting in a tighter seal and effectively enhancing sealing performance.

[0011] Preferably, the cover plate is provided with a locking mechanism, and the cover plate and the frame are locked together by the locking mechanism. The locking mechanism includes a hatch lock installed on the cover plate and a bolt fixedly installed on the hatch lock cylinder and capable of rotating with the lock cylinder. The inner wall of the side of the frame is provided with a limiting protrusion for engaging the bolt after rotation. After the bolt rotates to the bottom surface of the limiting protrusion, it contacts the bottom surface of the limiting protrusion to achieve limitation. During the locking process, the bolt rotates to the bottom surface of the limiting protrusion and contacts the bottom surface to achieve limitation, so that the bolt is stabilized in the closed position under the action of the limiting protrusion, thereby ensuring a firm lock between the frame and the cover plate.

[0012] Preferably, the cover plate and the frame are rotatably connected by a pivot pin. The frame has an opening for the pivot pin to pass through, and the cover plate has positioning insertion holes and fixing insertion holes for engaging both ends of the pivot pin. The pivot pin includes a pivot pin body that is slidably connected within the opening and whose outer end engages within the positioning insertion hole, and a grommet screw located outside the pivot pin body. The grommet screw is installed in the fixing insertion hole. Through the mutual cooperation between the pivot pin and the insertion hole, the rotatable connection and positioning between the cover plate and the frame are achieved. Simultaneously, the fixing screw secures one end of the fixing insertion hole, ensuring the stability of the connection and facilitating disassembly and replacement, thus reducing maintenance costs.

[0013] Preferably, the frame is detachably mounted on the base shell. Detachable mounting of the frame on the base shell facilitates its installation and maintenance.

[0014] Preferably, the upper end of the bottom shell is provided with an outwardly expanding card interface, and the lower end of the frame is snapped into the card interface. By providing an outwardly expanding card interface at the upper end of the bottom shell, the lower end of the frame is snapped into the limiting part, thereby limiting the frame.

[0015] The beneficial effects of this utility model are as follows: This utility model features an annular receiving groove on the frame, allowing the sealing strip to be placed in a ring shape within the receiving groove. A protrusion opposite to the sealing strip is provided on the cover plate. The protrusion presses against the sealing strip, causing it to deform as it is squeezed into the receiving groove and come into tight contact with the inner wall of the groove. This achieves a complete seal between the frame and the cover plate, preventing external moisture from entering the hatch through gaps and effectively improving the hatch's waterproof performance. Furthermore, after the cover plate is placed on the frame, the sealing strip remains compressed within the receiving groove, preventing it from loosening after the cover plate is placed on the frame.

[0017] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0018] Combination Figure 1 and Figure 2 As shown, this utility model discloses a waterproof RV door, including a base shell 1, a frame 2 installed on the base shell 1, and a cover plate 3 covering the frame 2. The frame 2 is provided with an annular receiving groove 21, and a sealing strip 4 is provided between the frame 2 and the cover plate 3. The sealing strip 4 is annularly arranged in the receiving groove 21. The cover plate 3 is provided with a protruding part 31 that protrudes outward and is arranged opposite to the sealing strip 4. The protruding part 31 presses against the sealing strip 4, causing the sealing strip 4 to deform toward the receiving groove 21 and make tight contact with the inner wall of the receiving groove 21.

[0019] This application provides an annular receiving groove 21 on the frame 2, so that the sealing strip 4 is placed in the receiving groove 21 in an annular shape. A protrusion 31 is provided on the cover plate 3 opposite to the sealing strip 4. The protrusion 31 presses against the sealing strip 4, so that the sealing strip 4 deforms when squeezed into the receiving groove 21 and makes tight contact with the inner wall of the receiving groove 21. This achieves a complete seal between the frame 2 and the cover plate 3, preventing external moisture from entering the hatch through the gap, effectively improving the waterproof effect of the hatch, and preventing items inside the hatch from getting moldy. In addition, since the sealing strip 4 is always squeezed in the receiving groove 21 after the cover plate 3 is closed on the frame 2, it also prevents the sealing strip 4 from loosening in the receiving groove 21 after the cover plate 3 is closed on the frame 2.

[0020] Reference Figure 4 As shown, a deformation cavity 41 is provided at the center of the inner side of the sealing strip 4 to expand the deformation space of the sealing strip 4. The deformation cavity 41 at the center of the inner side of the sealing strip 4 can effectively expand the deformation space of the sealing strip 4, ensuring that the sealing strip 4 can deform more flexibly when subjected to external force, thereby enhancing the sealing effect.

[0021] Combination Figure 4 and Figure 5 As shown, the sealing strip 4 includes a connecting and fixing part 42 with its lower end being the same width as the receiving groove 21, and a contact deformation part 43 with its upper end being used to contact the protrusion 31 and having a deformation space between it and the inner wall of the receiving groove 21. The connecting and fixing part 42 is set with the same width as the receiving groove 21 to stabilize the sealing strip 4 and prevent the sealing strip 4 from shifting within the receiving groove 21; the contact deformation part 43 is used to make abutting contact with the protrusion 31 of the cover plate 3 to achieve compression deformation of the deformation cavity 41.

[0022] As the cover plate 3 gradually covers the frame 2, the protrusion 31 comes into contact with the deformable part 43, causing the contact deformable part 43 to deform. The contact surface between the contact deformable part 43 and the protrusion 31 is completely deformed into the deformable cavity 41, thereby reducing the space inside the original deformable cavity 41. As the protrusion 31 gradually presses against the sealing strip 4, the two sides of the contact deformable part 43 gradually expand and deform towards the inner wall of the receiving groove 21 and the inner side of the cover plate 3, until the side walls of the contact deformable part 43 are tightly fitted to the inner wall of the receiving groove 21 and the inner side of the cover plate 3, respectively. Finally, the sealing strip 4 is squeezed and deformed to achieve a full-range sealing, forming a complete closed sealing ring between the frame 2 and the cover plate 3, further improving the sealing performance and effectively improving the waterproof effect between the cover plate 3 and the frame 2.

[0023] Reference Figure 3 As shown, the side of the sealing strip 4 that contacts the protrusion 31 protrudes outward from the receiving groove 21. When the sealing strip 4 is compressed, a portion of it embeds into the receiving groove 21, while the other portion extends beyond the edge of the receiving groove 21, continuing to perform its sealing function. This ensures that the sealing performance is not reduced due to the movement of the sealing strip 4, thus forming a more compact sealing effect and effectively enhancing the sealing performance. In addition, this design allows the sealing strip 4 to continue to be used even when it is worn, improving the sealing performance and service life of the hatch.

[0024] Combination Figure 1 and Figure 2 As shown, the cover plate 3 is provided with a locking mechanism 32. The cover plate 3 and the frame 2 are locked together by the locking mechanism 32. The locking mechanism 32 includes a hatch lock 321 installed on the cover plate 3 and a bolt 322 fixedly installed on the lock cylinder of the hatch lock 321 and can rotate with the lock cylinder. The inner wall of the side of the frame 2 is provided with a limiting protrusion 22 for locking the bolt 322 after rotation. After the bolt 322 rotates to the bottom surface of the limiting protrusion 22, it contacts the bottom surface of the limiting protrusion 22 to achieve limiting. By installing a hatch lock 321 on the cover plate 3 and a latch 322 fixedly installed on the lock cylinder of the hatch lock 321 and rotating with the lock cylinder, and by providing a limiting protrusion 22 on the inner wall of the side of the frame 2 for engaging the latch 322 after rotation, the latch 322 rotates to the bottom surface of the limiting protrusion 22 during the locking process and contacts the bottom surface to achieve limitation, so that the latch 322 is stabilized in the closed position under the action of the limiting protrusion 22, thereby ensuring a firm lock between the frame 2 and the cover plate 3 and preventing the hatch from being opened accidentally. At the same time, for ease of processing, the limiting protrusion 22 is set on the side corresponding to the latch 322 in this application.

[0025] Combination Figure 1 and Figure 2As shown, the cover plate 3 and the frame 2 are rotatably connected by a pin 5. The frame 2 is provided with an opening 23 for the pin 5 to pass through. The cover plate 3 is provided with a positioning insertion hole 33 and a fixing insertion hole 34 for inserting the two ends of the pin 5. The pin 5 includes a pin body 51 that is slidably connected in the opening 23 and whose outer end is inserted into the positioning insertion hole 33, and a grommet screw 52 located outside the pin body 51. The grommet screw 52 is installed in the fixing insertion hole 34.

[0026] During installation, first, the shaft pin body 51 is passed through the opening 23 on the frame 2. Then, one end of the shaft pin body 51 is placed into the positioning insertion hole 33 to position the shaft pin 5. Next, the other end of the shaft pin body 51 is aligned with the fixing insertion hole 34 and inserted into the fixing insertion hole 34. Finally, the nut screw 52 is rotated into the fixing insertion hole 34 through the outer end of the fixing insertion hole 34 to fix the shaft pin 5, ensuring the reliability of the shaft pin 5 connection.

[0027] In addition, when the operator needs to open the cover plate 3 for maintenance, the machine screw 52 can be easily loosened and the shaft pin 5 can be removed from the fixed insertion hole 34, making it easy to remove the cover plate 3, which facilitates disassembly and replacement and reduces maintenance costs.

[0028] Reference Figure 6 As shown, frame 2 is detachably mounted on bottom shell 1. Compared to bottom shell 1, frame 2, which is partially exposed to the outside, is more prone to damage. When frame 2 is damaged, only the damaged frame 2 needs to be replaced, without replacing the entire hatch, reducing unnecessary waste and facilitating the installation and maintenance of frame 2.

[0029] Combination Figure 6 and Figure 7 As shown, the upper end of the bottom shell 1 has an outwardly extending slot interface 11, and the lower end 24 of the frame 2 is inserted into the slot interface 11. The outwardly extending slot interface 11 on the upper end of the bottom shell 1 provides a precise positioning point for the frame 2 during assembly, ensuring accurate alignment and secure installation. When the lower end 24 of the frame 2 is inserted into the slot interface 11 on the upper end of the bottom shell 1, the lower end 24 of the frame 2 is securely engaged within the slot interface 11, achieving a tight fit between the frame 2 and the bottom shell 1.
