Overhead passenger car air conditioner snow protection structure, passenger car air conditioner and passenger car

Abstract

The invention relates to the technical field of brakes, and specifically relates to an overhead passenger car air conditioner snow protection structure, a passenger car air conditioner and a passengercar. The overhead passenger car air conditioner snow protection structure comprises a first supporting plate, a second supporting plate, a first snow protection mechanism and a second snow protectionmechanism, wherein the first supporting plate and the second supporting plate are arranged on a top panel of the passenger car air conditioner in parallel, the first snow protection mechanism is movably connected to the top of the first supporting plate and the top of the second supporting plate, the second snow protection mechanism is movably connected to the top of the first supporting plate and the top of the second supporting plate, and the height of the top end face of the first supporting plate and the height of the top end face of the second supporting plate are gradually reduced fromthe middle to the two ends. According to the invention, the first snow protection mechanism and the second snow protection mechanism are obliquely arranged on the two sides respectively to form a two-side slope structure, and when the air conditioner is turned off, a snow protection plate of the first snow protection mechanism and a snow protection plate of the second snow protection mechanism canbe closed under driving of a driving assembly, so that the problem that the passenger car air conditioner cannot be used due to snowfall is effectively solved. In addition, the two-side slope structure is beneficial to reducing accumulated snow on a baffle.

Description

technical field [0001] The invention relates to the technical field of brakes, in particular to a top-mounted passenger car air conditioner snow-proof structure, a passenger car air conditioner and a passenger car. Background technique [0002] The automotive air conditioning system is a device that cools, heats, ventilates and purifies the air in the cabin. It can provide a comfortable riding environment for the passengers, reduce the driver's fatigue intensity and improve driving safety. For passenger cars, the air conditioner is generally installed on the top of the passenger car. In the snowy environment in cold areas, the air conditioner on the passenger car often cannot be turned on due to snow and icing problems, but it cannot be used in the car when the demand is high. Air conditioning for heating. At present, the snow prevention measures in low temperature environment are mainly in the system and control logic. When the air conditioner is started, the defrosting p...

Problems solved by technology

For passenger cars, the air conditioner is generally installed on the top of the bus. In the snowy environment in cold areas, the air conditioner on the bus often cannot be turned on due to snow and icing problems, but it cannot be used in the car when the demand is high. air conditioning heating

At present, the snow prevention measures in the low temperature environment are mainly in the system and control logic. When the air conditioner is started, the defrosting program is used to remove snow or ice from the exposed heat exchanger through the heat emitted by the finned tube heat exchanger itself. etc. This method has a certain effect in solving the problem of snow accumulation and icing on the heat exchanger, but the external fan of the passenger car air conditioner is also exposed outside the whole machine, and it is very likely that the external fan will enter after the temperature is lower or it has snowed for a long time. The fan cannot be rotated due to snow and ice, so it cannot be turned on for heating
