The connection of the set of cockpit doors 12 and the cargo door 22 on the other side in the width direction W is similar and will not be described in detail below.

Referring to fig. 1, 2 and 3, as mentioned above, in the door 101 of the cargo vehicle provided in this embodiment, the connection mechanism 30 is disposed between the cockpit door 12 and the cargo door 22, and the connection mechanism 30 can make the cockpit door 12 overlap and adhere to and lock the surface of the door body of the cargo door 22, in other words, the cockpit door 12 can be locked on the cargo door 22, the cockpit door 12 and the cargo door 22 cannot move relative to each other, and when locked, the surface of the door body of the cockpit door 12 overlaps and contacts with the surface of the door body of the cargo door 22. In addition, a first hinge structure 40 for hinge-connecting with the body of the cargo vehicle 100 is provided on the side of the cargo door 22. The cargo door 22 can thus be hinged to the body of the cargo vehicle 100 by the first hinge structure 40.

In the above-mentioned solution, by providing the connection mechanism 30 between the cockpit door 12 and the cargo door 22, the cockpit door 12 can be overlapped and attached to and locked on the cargo door 22 by the connection mechanism 30 in the non-closed state, and will not rotate back and forth, so that the driver can operate the cargo compartment 20 conveniently. And the driver can also get in and out of the cab 10 conveniently. In addition, it can be understood that, under the severe environment, the connection between the cockpit door 12 and the cargo door 22 can be released, and the cockpit door 12 is closed to isolate the cockpit from the external environment, which is convenient.

In the present embodiment, referring to fig. 2 and 3, as a possible implementation, the cockpit door 12 is slidably connected to the cargo door 22, the cockpit door 12 is slidably connected to the cockpit 10, and the cargo door 22 is hinged to the vehicle body.

In a specific implementation, as for the connection manner between the cockpit door 12 and the cargo door 22, the cockpit door 12 may be slidably connected to the cargo door 22, for example, referring to fig. 1, the connection mechanism 30 includes: a first sliding portion 61 provided on an outer door body surface of the cargo door 22; and a second sliding portion (not shown) provided on the inner door body surface of the cockpit door 12; the first sliding portion 61 and the second sliding portion are in sliding fit with each other, so that the cockpit door 12 can slide relative to the cargo door 22 until the cockpit door 12 overlaps and fits with the surface of the door body of the cargo door 22. It can be understood that, as described above, the cockpit door 12 and the cargo door 22 are connected or disconnected in a sliding manner, so that the space occupied by the cockpit door 12 during movement can be saved, and the method is suitable for the situation of narrow operation space.

In the above arrangement, the cockpit door 12 and the cargo door 22 may be arranged in parallel, for example, the cockpit door 12 and the cargo door 22 may be disposed adjacent to each other in a closed state and substantially parallel to the running direction of the cargo vehicle 100.

With regard to the fixation of the cockpit door 12 to the cockpit 10, with continued reference to fig. 1, a sliding assembly is disposed on the inner door surface of the cockpit door 12 to enable the cockpit door 12 to slide relative to the cockpit 10, and the sliding assembly includes: a third sliding part fixedly connected to the inner door body surface of the cockpit door 12, and a fourth sliding part 71 in sliding fit with the third sliding part, the fourth sliding part 71 being adapted to be fixedly connected to a door frame of the cockpit 10 of the cargo vehicle.

As for the connection manner of the cargo door 22 and the vehicle body, for example, the cargo door 22 may be hinged to the body of the cargo compartment. Referring to fig. 3, a first hinge structure 40 is exemplarily provided between the body of the cargo compartment and the cargo compartment door 22, the cargo compartment door 22 is hinged to the body of the cargo compartment by the first hinge structure 40, and a hinge shaft of the first hinge structure 40 is vertically disposed and connected to a side of the cargo compartment 20 facing the cab 10.
