[0014] 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. Example
[0015] See Figures 1 to 8 As shown, a motorhome door structure includes a motorhome door frame 1, a screen door 3 and an outer door panel 4 connected by a door hinge 2. The screen door is located between the motorhome door frame and the outer door panel. In this embodiment, the motorhome door frame is fixed to the vehicle body, and the door hinge is a structure of the prior art, which is simply applied. like Figure 1 , Figure 2 , Figure 7 and Figure 8 In this embodiment, a plurality of outer door panel latches 5 are fixed to the side of the outer door panel, and the outer door panel latches are located at the edge away from the door hinge; the side of the screen door is provided with a latch connection structure 6; at the same time, a plurality of door frame latches 7 are fixed to the inner wall of the RV door frame, and the door frame latches are located on the side away from the door hinge; in this embodiment, the outer door panel latch is a sheet structure, and C-shaped slots are provided on the symmetrical sides, while the door frame latch is an n-shaped structure; like Figure 1 , Figure 2 and Figure 3 As shown, a door lock structure 8 is fixed in the middle of the screen door, and a vertical metal strip 9 connected to the door lock structure is provided on the edge of the screen door. The latch connection structure is fixed on the screen door, and a stud 10 is fixed on the outside of the vertical metal strip. The door lock structure can drive the vertical metal strip to rise and fall, so that the stud can be locked or unlocked in the recessed area of the door frame latch.
[0016] During assembly, the outer door panel and screen door are closed on the RV door frame. The vertical metal strip is raised and lowered by the door lock structure, so that the studs are engaged with the door frame latch, and the outer door panel latch is engaged with the latch connection structure.
[0017] like Figure 1 , Figure 2 and Figure 4 As shown, in practical applications, the locking connection structure includes a base 61, a top cover 62, a spring 63, a first torsion spring 64, and a retaining spring rotating support 65. During assembly, the base and the top cover are fixed with screws. A shaft protrusion 66 is provided inside the base. The retaining spring rotating support is sleeved on the shaft protrusion, and the protrusion 67 of the retaining spring rotating support extends out of the side of the base. A straight support block 68 is fixed to the side of the retaining spring rotating support. Its protrusion extends out of the side of the base and connects to the slider. When the vertical metal bar is raised or lowered, the protrusion can drive the spring to rotate and rotate the support rod, so that the I-shaped support block on it is in a vertical or horizontal state. When the I-shaped support block is in a vertical state, the two ends of the spring are in a clamping state, which can clamp and position the outer door panel latch. When the I-shaped support block is in a horizontal state, it will push the two ends of the spring outward, so that the outer door panel latch is separated from the spring, which facilitates the outer door panel latch disengagement operation. During assembly, the first torsion spring is sleeved on the shaft protrusion, with one end fixed inside the base and the other end fixed to the retaining spring rotation support, for resetting the retaining spring rotation support; the upper front of the top cover is provided with a retaining cavity 11, the bottom end of the insert spring is fixed to the lower back of the top cover, and the two ends of the insert spring are vertically parallel and pass through the retaining cavity, with the two ends of the insert spring respectively positioned low on the symmetrical side of the I-shaped support block; in use, the outer door panel latch is inserted into the retaining cavity, and the retaining spring rotation support rotates to drive the I-shaped support block to rotate. When the I-shaped support block is vertical, the two retaining springs are clamped and positioned on the symmetrical side of the outer door panel latch. When the I-shaped support block is horizontal, the I-shaped support block pushes the insert spring open and separates it from the outer door panel latch.
[0018] like Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, a slider 12 is fixed to the inner side of the vertical metal strip by screws. The stud passes through the vertical metal strip and its inner end is fixed to the slider. The protrusion of the retaining spring rotating support abuts against the protruding end of the slider. When the vertical metal strip rises and falls, the slider drives the protrusion to rotate the retaining spring rotating support, which in turn drives the straight-line support block to rotate. The rise and fall of the vertical metal strip causes the slider to rise and fall, and the slider and protrusion cause the retaining spring rotating support to rotate.
[0019] like Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, a tension spring fixing seat 13 is fixed to the top of the screen door, and a reset tension spring 14 is fixed between the tension spring fixing seat and the top of the slider. The reset tension spring, in conjunction with the tension spring fixing seat, works with the door lock structure primarily to facilitate the upward reset of the vertical metal strip, ensuring stable operation. To ensure the stable operation of the tension spring fixing seat, an anti-sagging connecting block 15 is fixed to the connection between the tension spring fixing seat and the screen door via a screw.
[0020] like Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, the door lock structure includes an inner door lock cover 81, an outer door lock cover 82, an inner handle 83, an outer handle 84, a main door lock slider 85, an eccentric cam 86, a second torsion spring 87, a rivet 88, a rotating cylinder 89, and a lock cylinder 810.

The inner handle is rotatably connected to the inner door lock cover, the eccentric cam is fixed to the inner handle, and the wheel edge of the eccentric cam abuts against the top edge of the main door lock slider. During assembly, the outer handle is rotatably connected to the outer cover of the door lock via rivets, and the second torsion spring is sleeved on the rivets. One end of the second torsion spring is abutted against the outer cover of the door lock, and the other end is abutted against the outer handle. A stop protrusion is fixed to the top of the outer handle. The rotating cylinder is connected to the lower part of the main slide block of the door lock, and the stop protrusion is attached to the top surface of the rotating cylinder. The vertical metal strip is fixed to the side of the main slide block of the door lock, and the vertical metal strip rises and falls synchronously with the main slide block of the door lock. The lock cylinder is located between the inner cover and the outer cover of the door lock, and the lock cylinder passes through the main slide block of the door lock.
[0021] like Figure 5 and Figure 6 As shown, the outer handle can rotate around the rivet. When the outer handle is lifted, it causes the outer handle to press down and simultaneously moves the main slider of the door lock. The main slider of the door lock then drives the vertical metal strip slider to open the door.
[0022] In practical application, the main slider of the door lock is provided with a vertical slide groove 16 in the middle, and a C-shaped relief groove 17 is provided on the symmetrical side wall of the middle of the vertical slide groove. The lock cylinder is located in the C-shaped relief groove. When in use, the key drives the lock cylinder to rotate, and the outer handle, under the action of the second torsion spring, causes the abutment protrusion to be engaged in the locking groove 18 of the lock cylinder. The downward abutment protrusion of the outer handle abuts against the outer wall of the lock cylinder, and the outer handle is tilted upward and the lock cylinder is in the unlocked state.
[0023] This utility model has positive effects: its structure is reasonably designed, including an outer door panel latch, a latch connection structure, a door frame latch, and a door lock structure. Through the cooperation of the above structures, the screen door and the outer door panel can be locked or unlocked simultaneously.
