[0033] The specific structure of the folding hatch door structure of the carriage is described below:

[0034] See also Figures 1 to 4 The foldable opening door structure of the vehicle compartment includes a first closing member 2 and a second closing member 3 arranged at an end of the first closing member 2, the first closing member 2 and the second closing member 3 are respectively connected to a first supporting member 201 and a second supporting member 301 in the cabin, the first closing member 2 is connected to a third closing member 4 at two ends perpendicular to a first direction, the first direction is the long side direction of the intersection of the first closing member 2 and the second closing member 3, the inner side of the third closing member 4 is connected to a third supporting member 402, and the forces of the first closing member 2, the second closing member 3 and the third closing member 4 are respectively shared by arranging the first supporting member 201, the second supporting member 301 and the third supporting member 402.

[0035] Furthermore, one end of the support rod 5 is engaged with the third support member 402, and the other end of the support rod 5 can be engaged with the first support member 201. The second support member 301 can be slidably engaged with the sliding component 6 at both sides perpendicular to the first direction, i.e., the short sides of the second closure member 3. The sliding component 6 is respectively arranged at one end of the third closure member 4 close to the second closure member 3.

[0036] Furthermore, the sliding assembly 6 includes a sliding rail 601 , and the third closing member 4 and the third supporting member 402 are provided with a first recessed portion 403 near the sliding rail 601 , and the sliding rail 601 is concealedly provided in the first recessed portion 403 to leave a larger space.

[0037] Furthermore, the support rod 5 is electrically connected to the smart room, and through the smart connection, the support rod 5 is automatically raised and lowered by induction without the need for manual opening and closing by the user.

[0038] Please continue reading Figure 4 and Figure 7 The slide rail 601 is connected to a slidable slider group 602 on a side away from the first recessed portion 403. The slider group 602 includes a first slider 6021 and a second slider 6022. The first slider 6021 and the second slider 6022 are linked to allow the hatch door to have sufficient opening space. The slide rail 601, the first slider 6021, and the second slider 6022 are slidably connected in sequence.

[0039] Please continue reading Fig. 9 The third support member 402 is provided with a first protrusion 401 along the first direction, and the first protrusion 401 is provided with a first hole 4011. The support rod 5 is provided with a second protrusion 501 at one end close to the first protrusion 401, and the second protrusion 501 is provided with a second hole 5011 that can be matched with the first hole 4011. By arranging the rotating shaft in the first hole 4011 and the second hole 5011, the bottom end of the support rod 5 can be slightly rotated relative to the third support member 402 to avoid being stuck.

[0040] Please continue reading Figure 6 , Figure 8 and Fig. 9 The support rod 5 also includes an outer shell 502 and a rod body 503 , and the rod body 503 is telescopically arranged in the outer shell 502 .

[0043] Furthermore, the first support member 201 and the second support member 301 are connected at their intersections by a hinge 1. The clamping of the first closing member 2 and the second closing member 3 and the connection of the first support member 201 and the second support member 301 improve the stability of the connection.

[0044] Furthermore, a third recessed portion 303 is provided at the bottom end of the outer side of the second closing member 3. The third recessed portion 303 leaves space for the user to manually open the hatch door.

[0045] The specific working process of the foldable cabin door structure of the utility model is described as follows:

[0046] After the support rod 5 senses and receives the command, the rod body 503 extends out of the outer shell 502, and the first closure member 2 and the first support member 201 are lifted up by the rod body 503, and then the second closure member 3 and the second support member 301 are lifted up along with the lifting of the first closure member 2 and the first support member 201. Based on the connection between the second support member 301 and the sliding assembly 6, the second closure member 3 and the second support member 301 only rise along the direction of the slider group 602. At this time, the second closure member 3 and the second support member 301 are folded relative to the first closure member 2 and the first support member 201, effectively avoiding the risk of accidental injury to the user due to the traditional rotary opening. When the rod body 503 is retracted into the outer shell 502, the first closing member 2 and the first support member 201 descend under the action of the rod body 503, and then the second closing member 3 and the second support member 301 descend as the first closing member 2 and the first support member 201 descend. Based on the connection between the second support member 301 and the sliding assembly 6, the second closing member 3 and the second support member 301 only need to descend along the direction of the slider group 602 to close the hatch.

[0047] If the user opens or closes the hatch manually, the user only needs to open or close it through the third recessed portion 303 . At this time, the height of the rod body 503 relative to the outer shell 502 is adjusted by the user.

[0048] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
