the buckling component can be configured on the door body and the door frame and is provided with a function of enabling the door body to be in an unlocking state or a locking state under the control of the rotating component, and the buckling component is connected with the rotating component through the connecting component;

the buckling assembly comprises a clamping seat connected with one end of the connecting assembly, an abutting part connected with the clamping seat, a buckling piece rotatably arranged on the door body, a clamping column part in clamping fit with the buckling piece, a limiting part for limiting the rotation angle of the buckling piece and an elastic part, wherein the abutting part is provided with a clamping part which is abutted against or not contacted with the buckling piece under the control of the clamping seat; when the abutting piece is in abutting contact with the buckling piece, the buckling piece and the clamping column piece are in a clamping fit state, when the abutting piece is out of contact with the buckling piece, the elastic piece generates upward rotating acting force on the buckling piece to force the buckling piece to rotate and separate from the clamping column piece, so that the door body rotates, the door body is in an unlocking state, the limiting piece is used for keeping the clamping groove of the buckling piece in an inclined upward state, and when the door body is closed, the clamping column piece is in contact with the inner side wall of the clamping groove to force the buckling piece to rotate, and therefore the buckling piece and the clamping column piece are reset and are in a clamping fit state; a kind of electronic device with high-pressure air-conditioning system

And the limiting component is connected to the rotating component and is positioned at the inner side of the door body, when the door body is in a locking state, the limiting component is contacted with the inner side surface of the door frame to limit the rotation of the door body, and when the rotating component rotates, the limiting component is driven to rotate together, and the limiting component is separated from the inner side surface of the door frame, so that the door body is in an unlocking state.

2. The door opening and closing device according to claim 1, wherein the clamping seat is provided with a clamping hook part, the abutting piece is provided with a containing groove for the clamping hook part to extend into, the clamping seat and the abutting piece are rotatably arranged on the door body, when the rotating part rotates, a pulling force is generated on the clamping seat through the connecting component, when the clamping seat rotates, a force is generated on the abutting piece to drive the abutting piece to rotate and separate from contact with the clamping piece.

3. The door opening and closing apparatus as claimed in claim 1, wherein one end of the connection assembly is rotatably connected to the rotating member through a first rotating member, the other end is rotatably connected to the card holder through a second rotating member, and a length of the connection assembly is adjustable.

4. The door opening and closing device according to claim 1, wherein the rotating member includes a rotating shaft rotatably installed on the door body, a turntable is fixedly installed at one end of the rotating shaft penetrating through the inner side of the door body, an installation part is integrally connected to the turntable, and the limiting member is connected to the installation part.

5. The door opening and closing apparatus according to claim 4, wherein the mounting portion has a plate-like portion extending in a thickness direction of the door frame, the plate-like portion is provided with a vertical groove in the thickness direction of the door frame, and the stopper member is connected to the vertical groove by a fastening member so as to be adapted to door frames of different thicknesses.

6. The door opening and closing apparatus according to claim 5, wherein the fastening member includes a locking bolt penetrating through the vertical groove and a screw sleeve screw-engaged with the locking bolt, one end of the locking bolt penetrates into the limiting member, and the screw sleeve is rotatably connected with the limiting member.

7. The door opening and closing apparatus according to claim 1, further comprising an angle limiting device including a socket piece fitted over the rotating member and rotatable with the rotating member, and a housing having side surfaces respectively contacting the two protruding portions to define a rotation angle of the socket piece.

8. The door opening and closing apparatus as claimed in claim 7, wherein the socket block has two slots, the housing is provided with a tab which can be inserted into or removed from the slots, and further comprising a driving source for driving the tab into or out of the slots, the tab corresponding to one slot of the socket block when one protrusion of the socket block contacts one side of the housing, and the tab corresponding to the other slot of the socket block when the other protrusion of the socket block contacts the other side of the housing, thereby restricting rotation of the rotating member.

9. A pickup truck comprising the door opening and closing apparatus according to any one of claims 1 to 8.

10. A vehicle comprising the door opening and closing device according to any one of claims 1 to 8.
