The utility model provides a vehicle-mounted air conditioner air inlet structure and a vehicle. The vehicle-mounted air conditioner air inlet structure comprises a gutter channel arranged below a ventilation cover plate and a blocking piece arranged in the gutter channel. The blocking piece divides the gutter channel into a front channel body and a rear channel body which are sequentially arranged in the front-back direction of the whole vehicle, the front channel body is communicated with the ventilation hole in the ventilation cover plate, the rear channel body is provided with a communication opening communicated with an air inlet of an air conditioner, and the blocking piece is provided with a through hole communicated with the front channel body and the rear channel body. A through hole communicating the front groove body with the rear groove body is defined between the blocking piece and the ventilation cover plate. According to the air inlet structure of the vehicle-mounted air conditioner, the gutter channel is divided into the front channel body and the rear channel body, external air firstly enters the front channel body through the ventilation holes in the ventilation cover plate, then enters the rear channel body through the through holes and then enters the air inlet through the communication opening, the air inlet effect can be guaranteed, and the air inlet effect is improved. And the rainwater can be prevented from splashing in the rear groove body and entering the air inlet of the air conditioner.

The utility model provides a foot support structure and a vehicle. The foot support structure comprises a main body used for being installed on an external carrier and an extending body arranged on the main body. Wherein a limiting part is arranged between the main body and the extending body, the limiting part limits the extending body to be in an initial state that the extending body extends forwards relative to the main body, and the extending body is driven to overcome the limitation of the limiting part and slide backwards relative to the main body. According to the foot support structure, the main body and the extending body are included, and the limiting part is arranged between the main body and the extending body, so that the extending body can be limited to be in the initial state that the extending body extends forwards relative to the main body, the feet of a passenger can be supported, and the riding comfort of the passenger is improved; therefore, the extension body can be driven to slide backwards relative to the main body so as to crumple to protect the safety of the legs of the passenger, so that the injury to the legs of the passenger can be reduced, and the riding safety is improved.

This utility model relates to the field of curtain tracks and discloses a silent sliding curtain track mechanism, including a track body, two sealing covers, and a suspension mechanism. A support block is fixedly installed on the upper inner side of the track body, and protrusions are provided on both sides of the inner wall at the lower inner side of the track body. Sound-insulating cotton is provided on the inner wall at the lower inner side of the track body. The suspension mechanism includes a movable block, a hanging ring fixedly installed at the lower end of the movable block, and a fixed post fixedly installed on the upper inner side of the movable block. First rollers are rotatably mounted on both sides of the fixed post, second rollers are rotatably mounted on both sides of the outer end of the fixed post, and third rollers are rotatably mounted on both sides of the outer end of the fixed post. In this utility model, during movement, the first roller reduces friction and improves sliding smoothness, while the second roller can move between the two protrusions, effectively ensuring that the second roller does not deviate from the track.
