[0030] Please refer to Figures 1 to 7 together, and now a door connection hinge provided by an embodiment of the present invention will be described.

[0031] As Figures 1 to 5 shown, a door connection hinge according to an embodiment of the present invention includes a vehicle body connection member 100, a first rotating shaft 200, a transmission member 300, a second rotating shaft 310, a positioning rod 410, and a door connection member 400; the transmission member 300 is pivotally connected to the vehicle body connection member 100 through the first rotating shaft 200; the axial direction of the second rotating shaft 310 is perpendicular to the axial direction of the first rotating shaft 200, and the second rotating shaft 310 is arranged on the transmission member 300; the door connection member 400 is pivotally connected to the transmission member 300 through the second rotating shaft 310; the positioning rod 410 is arranged on the door connection member 400, one end of the positioning rod 410 is connected to the door connection member 400, and a ball head pin 411 is arranged at the other end of the positioning rod 410; the vehicle body connection member 100 is provided with a guiding chute 110 for slidingly connecting with the ball head pin 411; when the ball head pin 411 slides along the guiding chute 110, the ball head pin 411 drives the door connection member 400 to rotate around the second rotating shaft 310 and drives the transmission member 300 to rotate around the first rotating shaft 200.

[0032] The body connecting member 100 is used for fixedly connecting with the body of an automobile, and the door connecting member 400 is used for fixedly connecting with the door of an automobile. The body connecting member 100 can be welded or installed on the body using screws, and the door connecting member 400 can be welded or connected to the door using screws. The transmission member 300 can rotate around the first rotating shaft 200, and the body connecting member 100 can rotate around the second rotating shaft 310. The path trajectory of the guiding chute 110 is the same as the movement trajectory of the door when opening and closing. Since the ball head pin 411 of the positioning rod 410 of the door connecting member 400 is slidably connected with the guiding chute 110, when the door connecting member 400 slides along the guiding chute 110 through the ball head pin 411, the movement trajectory of the door connected to the door connecting member 400 will be the same as the path trajectory of the guiding chute 110. When the ball head pin 411 of the present embodiment slides on the guiding chute 110, it can cause the door connecting member 400 to rotate around the second rotating shaft 310, and at this time, the transmission member 300 rotates around the first rotating shaft 200. When the transmission member 300 rotates around the first rotating shaft 200, it can also drive the door connecting member 400 to rotate around the first rotating shaft 200. That is, when the door connecting member 400 rotates around the first rotating shaft 200, it can simultaneously rotate around the second rotating shaft 310, achieving the function of a hybrid scissor door hinge, that is, the door connected to the door connecting member 400 swings outwards and flips upwards when opening, as Figure 6 , Figure 7 shown, to open the scissor-type door.

[0033] It should be noted that the specific path of the guiding chute 110 needs to be determined according to the specific movement path of the door; if the specific movement path of the scissor-type door is a curved trajectory, then the path of the guiding chute 110 is the same as this curved trajectory.

[0034] In the present embodiment, the transmission member 300 is pivotally connected to the body connecting member 100 through the first rotating shaft 200, the door connecting member 400 is pivotally connected to the transmission member 300 through the second rotating shaft 310. The door connecting member 400 is provided with a positioning rod 410 with a ball head pin 411, and the body connecting member 100 is provided with a guiding chute 110 that is slidably connected with the ball head pin 411. When the ball head pin 411 moves along the path of the guiding chute 110, the ball head pin 411 drives the door connecting member 400 to rotate around the second rotating shaft 310 and drives the transmission member 300 to rotate around the first rotating shaft 200, thereby driving the door connecting member 400 to realize the function of swinging outwards to open the door and simultaneously swinging upwards to open the door, so as to open and close the scissor-type door; the door connection hinge limits the opening and closing direction of the door through the ball head pin 411 of the positioning rod 410 of the door connecting member 400 and the guiding chute 110 of the body connecting member 100, enabling the door to open outwards and upwards at the same time. Its hinge structure is simpler, the installation is more convenient, facilitating the installation of the hinge and convenient for use.

The body connector 100 is a sheet-shaped connector, and the receiving groove 120 is a notch on the sheet-shaped connector. The transmission member 300 is provided at the groove. There are two hinged support ears 130, which are provided on both sides of the receiving groove 120. The receiving groove 120 is used to form a hinged seat with the first rotating shaft 200, thereby ensuring that the first rotating shaft 200 can be better pivoted on the body connector 100, and reducing the situation where the transmission member 300 collides with the outer parts.

[0036] In a preferred embodiment of the present invention, referring to Figure 3 and Figure 4 The body connector 100 is provided with a limiting member 140, which is located on the side of the receiving groove 120 away from the hinged lug 130, and the door connector 400 is located on the side of the transmission member 300 facing the limiting member 140, and the guide slide groove 110 is provided on the limiting member 140. The limiting member 140 is U-shaped, and cooperates with the receiving groove 120 to form a protection groove for protecting the transmission member 300. The guide slide groove 110 is provided on the limiting member 140 to facilitate the arrangement of the positioning rod 410, so that the ball pin 411 of the positioning rod 410 on the door connector 400 can better slide with the guide slide groove 110. The limiting member 140 can also abut against the door connector 400 to limit the rotation range of the transmission member 300 and prevent the transmission member 300 from being offside when rotating around the first rotation axis 200.
