Further, in another embodiment of the present invention, a driving device 600 for driving the half-opened plate 203 to slide along the sliding seat 500 is disposed at the top inside the mounting frame 100, the driving device 6 includes a driving rod 601, and a steering engine 602 for driving the driving rod 601 to reciprocate axially, the driving rod 601 is provided with rubber wedges 603 having the same number as the half-opened plate 203, and the top of the half-opened plate 203 is provided with a rectangular slot 208 matched with the rubber wedges 603.

Under the drive of the driving device 600, the choke strip 204 arranged on the half-open plate 203 is cancelled, and the opening and closing of the half-open plate 203 are completely controlled by the driving device 600.

The steering engine 602 is hinged to the transmission rod 601, the steering engine 602 drives the end of the transmission rod 601 to be connected to form a crank link mechanism, so that the transmission rod 601 is driven to axially reciprocate, contact and separation of the rubber wedge 603 and the rectangular open slot 208 are achieved, the rubber wedge 603 is of a triangular structure, the width of the rectangular open slot 208 is the same as the height of the rubber wedge 603, when the top of the rubber wedge 603 enters the rectangular open slot 208, the semi-open plate 203 is driven to reach the maximum displacement position, and therefore the deformation state of the grating is automatically controlled.

An inner grid 300 is arranged in the mounting frame 100 on the back side of the grid body assembly 200, a wind breaking angle net 301 is arranged on the inner grid 300 right opposite to the air inlet 700, and a net groove 302 matched with the end parts of two adjacent half-open plates when the end parts are combined is arranged at the edge of the wind breaking angle net 301.

The inner side of the inclined chamber 400 is extended to the inner grill 300, and the height of the inner end of the inclined chamber 400 is higher than the height of the inner side of the sliding seat 500.

In order to treat the corpses of the winged insects entering the grille, the movable half-open plate 203 is arranged, mechanical vibration is easily generated on movable parts on an automobile structural part, and therefore abnormal sound generated by the vibration of the grille is reduced through two measures, one is that the rubber wedge 603 is arranged on the transmission rod 601, and the other is that the edge of the inner grille 300 is arranged on the installation frame 100 through a sponge pad, so that the rubber wedge 603 can reduce mechanical contact between the transmission rod 601 and the fan plate 202, transmission of the mechanical vibration is reduced, the mechanical vibration is further counteracted through the sponge pad when the inner grille 300 is vibrated, and the possibility of the abnormal sound and the vibration generated by the grille is effectively reduced.

If the included angle between the choke strip 204 and the half-open plate 203 is smaller than or equal to 90 °, after the two adjacent half-open plates 203 are in contact with each other, the cavity formed by the two adjacent half-open plates 203 and the choke strip 204 on the half-open plate 203 can cause airflow entering the cavity to form a vortex in the length direction of the half-open plate 203, and then an air column is formed between the wind resistance inclined plane bodies 2041 of the two wind resistance strips 205, and the formation of the air column will prevent the airflow from continuously flowing into the cavity and guide the airflow to the two adjacent wind resistance inclined plane bodies 2041.

Wherein, because natural air current does not have fixed angle of flow, even under the high-speed circumstances, lateral air current still can exist, for this reason, install the windage inclined plane body 2041 of windage strip 204 at the tip of half-opening board 203 through connecting seat 2042, its effect can be according to the difference of air current direction, make windage inclined plane body 2041 rotate around the axostylus axostyle that is used for erection joint seat 2042 freely, make the adjustment of adaptability to make windage inclined plane body 2041 obtain ideal windward side constantly, produce the windage that can drive half-opening board 203 fast and remove.

Further, in order to optimize the angle of the wind resistance inclined plane body 2041, if the included angle between the choke strip 204 and the half-open plate 203 is greater than or equal to 120 °, the effective force application area of the choke strip 204 against the wind pressure is reduced, and under the action of no external driving device, the vehicle speed needs to be increased to enable the choke strip 204 to be subjected to the wind pressure capable of driving the choke strip 204 to move, so that under the condition of increasing the vehicle speed, the speed of crashing flying insects is already reached, and at the moment, the air inlet 700 is not closed, so that the cleaning effect of the air inlet is affected, therefore, the angle between the choke strip 204 and the fan plate 202 is 90-120 °, and the wind pressure borne by the choke strip 204 can be enabled to drive the half-open plate 203 to close the air inlet 700 when the vehicle speed reaches 60km/h under the windless condition.

The sensor module comprises a distance sensor, a pressure sensor and a wind speed sensor;

the pressure sensor is used for detecting the wind resistance acting force borne by the half-open plate of the automobile grille;

the wind speed sensor is used for acquiring the wind speed of a cavity between an inner grid plate and a grid body assembly of the automobile grid in real time.

Due to the uncertainty of the natural wind and the speed of the vehicle during the travel of the vehicle, the vehicle grille cannot be operated in a completely controllable manner.

The concrete mode that the control mode intervenes the automation operating condition of car grid under the wind-force effect does: when the automobile runs at a low speed and the wind speed of a cavity between the inner grating and the grating body assembly reaches a set value, the driving device of the half-open plate is controlled to automatically work, the driving device drives the half-open plate to slide to open the air inlet net arranged on the fan plate, and the function of the driving device is that when natural wind is large, the speed and the natural wind power of the automobile do not provide enough driving force for the wind blocking strips, so that the half-open plate is in an unstable state, and the driving device is directly involved and actively controlled;

when the automobile runs at a low speed, the sensor module detects that the relative position distance between the fan plate and the half-open plate reaches the maximum, the driving device is powered off, at the moment, the natural wind power and the automobile speed reach the driving force which can provide enough wind blocking strips to drive the half-open plate to close the air inlet, the driving device is powered off, and the half-open plate enters a state of being controlled by the wind power only;

when a function key connected to a controller for controlling the driving device is started, the driving device enters an active control mode, an operator controls the driving device to drive the relative movement distance between the half-open plate and the fan plate, artificial active control is performed, in the subsequent practical process, the air inlet and the air inlet net are opened and introduced into different heat dissipation systems of new energy automobiles, and the air inlet mode for actively controlling air inlet flow is realized.
