The interlock trigger button 1 is inserted into the guide bolt 3 and is closely matched with the guide bolt 3. When the fuel filler cap is closed, one end of the interlock trigger button 1 is pressed against the fuel filler cap 16, and the interlock trigger button 1 The other end is provided with a through hole 1a. The opening rocker arm 5 is V-shaped, the middle of which is fixed on the interlock opening bracket 4 through the rocker arm shaft 8, and the opening rocker arm 5 can rotate around the rocker arm shaft 8, and one end of the opening rocker arm 5 extends into the interlock trigger in turn. In the through hole 1a of the button 1 and in the opening rocker chute 4a of the interlocking opening bracket 4, and the opening rocker 5 is slidably matched with the opening rocker chute 4a, and the opening rocker 5 is restricted by opening the rocker chute 4a of rotation angle. The other end of the opening rocker arm 5 is provided with a pull rod sleeve 6, and the opening rocker arm 5 is clamped with one end of the transmission pull rod 7 through the pull rod sleeve 6, and the other end of the transmission pull rod 7 is connected with the interlocking lock body assembly. Return torsion spring 9 is enclosed within on the rocking arm rotating shaft 8, and one end of return torsion spring 9 is fixed on the interlocking opening support 4, and the other end of return torsion spring 9 acts on opening rocking arm 5.

The interlock lock body assembly includes a transmission pull rod 7 , a pull rod sleeve 6 , an interlock bracket 11 , a dead bolt shaft 12 , an interlock shield 13 , a dead bolt return torsion spring 14 and a dead bolt 15 . The interlock bracket 11 is fixed on the side wall outer panel 19 , the interlock shield 13 is clipped on the interlock bracket 11 , and the interlock shield 13 is provided with a lock tongue slide groove 13 a. Dead bolt 15 is bar-shaped, and its middle part is fixed on the interlocking support 11 by dead bolt rotating shaft 12, and dead bolt 15 can rotate around dead bolt rotating shaft 12, and one end of dead bolt 15 is provided with pull bar cover 6, and dead bolt 15 passes through this The pull rod cover 6 is clamped with the other end of the transmission pull rod 7; the other end of the lock tongue 15 has a hook 15a, and the hook 15a is located in the lock tongue chute 13a and is slidably fitted with the lock tongue chute 13a. The sliding groove 13a is used to limit the rotation angle of the dead bolt 15. When the fuel filler cap 16 is opened, the lock tongue 15 can be hooked on the sliding door interlocking bolt 17 through the hook portion 15a, and the sliding door interlocking bolt 17 is locked to limit the opening operation of the sliding door 20 .
