The electric vehicle entrance style gate device provided by the embodiment of the invention includes a controller 100, a feed gate 300 and a motor 400, wherein the inlet grill 300 is disposed on the front side of the electric vehicle, and the drive motor 400 is connected to the grille When the controller 100 knows that the electric vehicle is in the defrosting mode, the motor 400 drives the inlet grill 300 to be closed, and the controller 100 knows that the electric vehicle is in the normal mode, The motor 400 drives the inlet grill 300 to open.

When the electric vehicle in the electric vehicle enters the style gate device is in the defrosting mode, the motor 400 drives the inlet grill 300 to be closed, and the controller 100 knows that the electric vehicle is in the normal mode. The motor 400 drives the inlet grill 300 to open. It can be seen that when the electric vehicle is in the defrosting mode, the front side grille 300 does not enter the air, so the heat on the condenser 200 is not taken away, the defrosting time is shortened, and the energy of the electric vehicle is reduced. Consumption, extending the cruising range.

It should be noted that the controller 100 in the embodiment of the present invention is a structure well known in the art, and the functions of the controller 100 itself are applied to solve the problems existing in the prior art, and the functions of the controller 100 are not performed. Improve.

In order to optimize the above technical solution, the electric vehicle entrance grille device further includes a temperature sensing package 500 disposed at the condenser 200, and the temperature sensing package 500 is configured to detect a real-time temperature of the condenser 200 when the real-time temperature When the temperature is greater than the preset temperature of the controller 100, the motor 400 drives the inlet grill 300 to open.

Among them, the preset temperature differs depending on the region in which it is located. When the real-time temperature reaches the preset temperature, it indicates that the frost on the condenser 200 has melted, and the inlet grille 300 is opened, and the fresh air enters the vehicle through the inlet grill 300, so that the condensed water on the condenser 200 can be obtained. The rapid discharge prevents the water remaining on the condenser 200 from being frozen into frost when the air conditioner is switched to the heating mode, which affects the performance of the subsequent air conditioning heating operation.

The entrance style grille 300 in the embodiment of the present invention can be flexibly opened or closed, wherein the structure of the intake grille 300 that is driven by the motor 400 to open and close is realized, and the intake grille and the closed grille 300 are configured.

In the defrosting mode, after the inlet grille 300 is closed, there is no intake air on the front side of the car, and the frost on the condenser 200 melts rapidly. The heat of the condenser 200 is not absorbed, thereby shortening the defrosting time and reducing the energy consumption.

During the defrosting process, the real-time temperature of the condenser 200 is obtained, and when the real-time temperature is greater than the preset temperature, the motor 400 is driven into the style grid 300 to be turned on. When the controller 100 detects that the real-time temperature of the tube temperature sensing package 500 reaches the preset temperature, it indicates that the frost on the condenser 200 has melted, and the controller 100 controls the motor 400 to drive the inlet grill 300 to be in an open state. The electric vehicle air conditioner continues to operate in the defrosting mode, so that the condensed water on the condenser 200 can be quickly discharged, and the residual water on the condenser 200 is prevented from being frozen into frost when the air conditioner is switched to the heating mode, which affects the subsequent air conditioning heating. Performance of the run.

(2) It is known that the electric vehicle is in the normal mode, and the motor 400 is driven into the style grill 300 to be opened.

The inlet grill 300 is normally opened. When the electric vehicle is in the normal mode, the inlet grill 300 is in an open state to facilitate heat exchange of the condenser 200. It can effectively improve the defrosting effect, improve the comfort of the occupants, and reduce the energy consumption of the electric vehicle air conditioner.
