[0018] See Figure 1-Figure 3 As shown, this specific embodiment adopts the following technical scheme: it includes a vehicle refrigerator drawer 1 and a drive locking assembly 2; wherein, the drive locking assembly 2 also includes a supporting base plate 3, a telescopic slide rail 4, an L-shaped drawer fixing frame 5, a slide rod 6, a drawer automatic pop-up bracket 7, a damping gear 8, a rack 9, a transmission belt 10, a winding roller 11, an elastic coil spring 12, a reset spring 13, and a locking elastic buckle 14; the left and right sides of the supporting base plate 3 are respectively fixed with telescopic slide rails 4, and the outer side of the telescopic slide rail 4 is connected with an L-shaped drawer fixing frame 5; a pair of slide rods 6 are respectively fixed on the edges of both sides of the front end of the supporting base plate 3, and a drawer automatic pop-up bracket 7 is movably connected between the two slide rods 6, and a damping gear is inlaid and fixed on one side in the middle of the drawer automatic pop-up bracket 7. The damping gear 8 and the rack 9 at the middle front end part of the support base plate 3 are kept in meshing. A transmission belt 10 is connected to one side of the rear end of the automatic drawer pop-up bracket 7. The transmission belt 10 extends backward along the reserved groove of the support base plate 3 and is wound around the winding roller 11 at the rear end of the support base plate 3. One side of the winding roller 11 is coaxially connected with an elastic coil spring 12; the locking elastic buckle 14 is connected to the reserved recess at the front end of the support base plate 3 through a reset spring 13; the front end of the vehicle refrigerator drawer 1 is fixed to the upper end of the automatic drawer pop-up bracket 7, and the two sides of the vehicle refrigerator drawer 1 are fixed on the L-shaped drawer fixing frame 5. An integrated card joint 15 is provided at the bottom of the front end of the vehicle refrigerator drawer 1, and the card joint 15 cooperates with the locking elastic buckle 14 to realize the locking of the vehicle refrigerator drawer 1.

[0019] The elastic coil spring 12 drives the winding roller 11 to rotate and drag the transmission belt 10, so that the drawer automatically pops out of the bracket 7 and drives the unlocked vehicle refrigerator drawer 1 to automatically pop out. The damping gear 8 is composed of a damping bearing and a gear part, and the damping gear 8 limits the rebound speed of the drawer automatically pops out of the bracket 7.

[0020] In addition, the locking elastic buckle 14 forms two structures of front-pressing rebound locking buckle and rear-pulling unlocking buckle through the cooperation of the return springs 13 on both sides; the length of the rack 9 is half the length of the supporting base plate 3, and the rear end of the rack 9 is connected to the raised limiting edge.
