[0010] Furthermore, a left-side flange is provided on the left side of the car floor facing upwards, and the frame includes a left frame plate opposite to the left-side flange of the car floor, forming an air intake channel on the left side of the car floor between the left-side flange of the car floor and the left frame plate.

[0011] Furthermore, the upper end of the left panel of the enclosure extends to the right to provide a left side panel, which blocks the air intake channel on the left side of the car bottom.

[0012] Furthermore, a right-side flange is provided on the right side of the car floor, and the frame includes a right frame plate opposite to the right-side flange of the car floor, forming an air intake channel on the right side of the car floor.

[0013] Furthermore, the upper end of the right panel of the enclosure extends to the left to provide a right side shield, which blocks the air intake channel on the right side of the car bottom.

[0014] Furthermore, a car floor reinforcing rib is provided at the bottom of the car floor.

[0015] Furthermore, the enclosure frame is fixedly connected to the reinforcing ribs of the car floor.

[0016] Furthermore, a floor is provided on the car floor.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1) This utility model sets a frame on the outside of the car floor, and forms an air intake channel between the frame and the car floor to realize air intake under the car;

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-6 A ventilated elevator car bottom assembly includes a frame, a car bottom plate 100 disposed in the frame, and a floor 105 disposed on the upper end of the car bottom plate 100. The frame and the car bottom plate 100 form an air intake channel from bottom to top. The air intake channel allows airflow to enter the upper end of the car bottom plate 100 from the bottom of the car bottom plate 100 and then enter the elevator car.

[0030] Continue reading Figures 1-6 In one embodiment of this utility model, the frame is U-shaped, including a rear frame panel 101 and a left frame panel 102 and a right frame panel 103 respectively disposed on the left and right sides of the rear frame panel 101.
