[0023] Furthermore, a third through hole 2001 is provided at the front end of the body shoulder 2002, and a fourth through hole 5011 is provided at the lower ends of the two swing arms 501. The lower ends of the two swing arms 501 pass through the fourth through holes 5011 on the two swing arms 501 through screws 6 and are inserted into the third through hole 2001 at the front end of the body shoulder 2002.

[0024] Furthermore, the lower ends of the two swing arms 501 can be rotated at the front end of the body shoulder 2002 through a screw 6. A flange surface 6001 is provided at the front end of the screw 6. The flange surface 6001 of the screw 6 contacts the outer end surface of the front end swing arm 501, and grease is applied between the two and on the screw 6 passing through, so that the two swing arms 501 can rotate.

[0025] Furthermore, a first through hole 1001 is provided on one side of the hatch cover member 1, and a circular hole 7014 is provided in the middle of the fixed shaft 7011. The driving member 7, the body member 2 and the hatch cover member 1 are connected through a pin shaft 3 that passes through the circular hole 7014, the upper end of the middle part of the body member 2 and the first through hole 1001 in sequence. Bushings 9 are provided on the pin shaft 3 and between the driving member 7 and the body member 2 and between the body member 2 and the hatch cover member 1. The hatch cover member 1 and the driving member 7 are both fixedly connected to the pin shaft 3, so that when the hatch cover member 1 rotates, the driving member 7 is synchronously driven to rotate. The fixed shaft 7011 of the drive seat 701 passes through the gap between the two swing arms 501. When the hatch cover is in the closed state, the fixed shaft 7011 contacts the inner side surfaces of the two swing arms 501; when the hatch cover is in the open state, the fixed shaft 7011 contacts the inner side surface of one swing arm 501, and does not contact the inner side surface of the other swing arm 501.

[0026] Furthermore, a second through hole 1002 is provided on the other side of the hatch cover 1 , and a ball stud 8 is fixedly connected to the second through hole 1002 .

The upper end of the limiting bolt 4 is provided with a first end face 4001. The limiting bolt 4 can move in the waist hole 2003 to determine the position and then be fixed by the limiting nut 10.

[0028] Furthermore, the front ends of the two drive seats 701 are each provided with a fifth through hole 7012, and the two drive columns 702 are respectively inserted into the two fifth through holes 7012 and fixed by internal threads. The lower end of the drive member 7 is provided with a bottom surface 7013. When the hatch cover is fully opened, the bottom surface 7013 of the drive seat 701 contacts the first end surface 4001 of the limiting bolt 4 on one side. When the hatch cover is fully closed, the bottom surface 7013 of the drive seat 701 contacts the first end surface 4001 of the limiting bolt 4 on the other side. By adjusting the position of the limiting bolt 4 in the waist hole 2003, the maximum position of the hatch cover opening can be adjusted. When the hatch cover is opened and closed, the hatch cover drives the hatch cover member 1 to rotate, so that the hatch cover member 1 synchronously drives the drive member 7 to rotate. When the hatch cover is opened, the driving column 702 on one side of the front end of the hatch cover component 1 will push a swing arm 501 to rotate, so that the spring seats 503 on the two swing arms 501 are closed and the spring 502 is compressed. When the hatch cover is closed, the driving column 702 on one side is reset. At the same time, the driving column 702 is reset and the swing arm 501 is reset by the thrust of the spring 502. After the driving column 702 on one side is reset, the driving column 702 on the other side of the front end of the hatch cover component 1 will push the other swing arm 501 to rotate in the opposite direction, so that the spring seats 503 on the two swing arms 501 are closed again and the spring 502 is compressed. The spring 502 is used to buffer the hatch cover when it is opened and closed, so that the buffer mechanism 5 can effectively control the speed of the hatch cover component 1 in the open or closed state.

[0029] Working principle: When in use, when the hatch cover is fully opened, the bottom surface 7013 of the drive seat 701 contacts the first end surface 4001 of the limit bolt 4 on one side; when the hatch cover is fully closed, the bottom surface 7013 of the drive seat 701 contacts the first end surface 4001 of the limit bolt 4 on the other side; by adjusting the position of the limit bolt 4 in the waist hole 2003, the maximum position of the hatch cover opening can be adjusted; when the hatch cover is opened and closed, the hatch cover drives the hatch cover member 1 to rotate, so that the hatch cover member 1 drives the drive member 7 to rotate synchronously; when the hatch cover is opened, the drive column 702 on the front side of the hatch cover member 1 will push a swing arm 501 into When the hatch cover is closed, the driving column 702 on one side is reset. At the same time, the driving column 702 is reset and the swing arm 501 is reset by the thrust of the spring 502. After the driving column 702 on one side is reset, the driving column 702 on the other side of the front end of the hatch cover 1 will push the other swing arm 501 to rotate in the opposite direction, closing the spring seats 503 on the two swing arms 501 again and compressing the spring 502. The spring 502 is used to buffer the hatch cover when it is opened and closed, so that the buffer mechanism 5 can effectively control the speed of the hatch cover 1 in the open or closed state.
