The window opening mechanism 3 is arranged on the window opening trolley 1 in a telescopic mode, when the window opening mechanism 3 stretches out from the window opening trolley 1 and is matched with the locking pin 4, the locking pin 4 can be unlocked from the positioning locking mechanism 6, and the locking pin 4 is driven to synchronously slide along with the window opening trolley 1, so that the folding window body 5 can be opened or the opening degree of the folding window body 5 can be changed.
As shown in fig. 2, the locking pins 4 are vertically distributed in rectangular grooves formed in the lower part of the front end of the folding window body 5 (i.e., in the lower right corner of fig. 1). Two pin bosses 99 are arranged in the rectangular groove at intervals, and concentric holes are formed in the two pin bosses 99. The locking pin 4 is slidably inserted into the two concentric holes and can be lifted up by an external force. The positioning lock mechanism 6 includes a guide groove 602 distributed in a horizontal direction at a bottom position of the folding window frame 2 and a plurality of pin bosses 601 provided at intervals in the guide groove 602. The lower end of the locking pin 4 is tapered to slide in the guide groove 602 in either the locked state or the unlocked state after lifting. When the tapered end of the locking pin 4 is inserted into the pin hole on the pin sleeve 601 at a certain position, the locking positioning of the locking pin 4 is realized, and the locking positioning of the folding window body 5 in a closed, opened or certain opening state is achieved. The upper end position of the locking pin 4 is also fixedly provided with a circular unlocking disc 8, and the windowing mechanism 3 can be matched with the unlocking disc 8 to jack up the unlocking disc 8 and the locking pin 4, so that the locking pin 4 is separated from the pin sleeve 601, and a foundation is provided for opening and closing the folding window body 5 or adjusting the opening of the folding window body 5.
The guide rail 7 is provided for sliding of the window trolley 1 and is fixed to the bottom of the folding window frame 2 in the horizontal direction. In order to ensure that the window trolley 1 only slides along the length direction of the guide rail 7, limiting plates can be respectively arranged on the parts, located on two sides of the window trolley 1, of the guide rail 7, and a dovetail-shaped sliding block and a dovetail-shaped sliding groove for the dovetail-shaped sliding block to slide are respectively arranged on one side, opposite to the folding window body 5, of the window trolley 1 and the corresponding limiting plates.
As shown in fig. 3, the window trolley 1 includes a rectangular vehicle body 107, a traveling wheel 104 is provided at the lower part of the vehicle body 107, a gear motor 103 is provided in the vehicle body 107, and a driving gear 101 in driving engagement with a driven gear 102 on the wheel shaft of the traveling wheel 104 is provided on the output shaft of the gear motor 103. As shown in fig. 2 and 3, the window opening mechanism 3 mainly includes a telescopic shaft 302 slidably provided on the side of the vehicle body 107 facing the folding window body 5, and an unlocking member 304 and a window opening member 301 fixed to the telescopic shaft 302 at a position at one end outside the vehicle body 107.
