The grille blade is an important part of the active air intake grille.

[0003] The traditional grille blade processing method is to connect the inner plate and the outer plate by hot plate welding or vibration friction welding. The grille blade processed by the above method has the problems of low qualified rate and large equipment investment. The inner and outer plate clamping form cannot be used for assembly to reduce the assembly cost and improve the product qualified rate.

[0004] In low temperature environment, water in the air is easy to condense into ice at the connection of the grille blade. When the vehicle is driven or parked in a humid environment, water may penetrate into the gap of the blade connection, and quickly freeze at low temperature.

[0035] Embodiment one: please refer to Figures 1-9 As shown in the figure, in the prior art, the contact surface between the blade and the inner plate is provided with an electric heating layer to thaw the blade, which can thaw the ice, but cannot clean the deposits on the gap of the grid blade connecting part, and the water droplets remaining on the thawed grid blade have the risk of secondary freezing.

[0036] The inner and outer plate clamping type active air inlet grid with auxiliary heating ice breaking mechanism in the embodiment includes a grid connecting plate 1 and multiple groups of grid blades arranged on both sides of the grid connecting plate 1, and an auxiliary heating ice breaking assembly for auxiliary heating and ice breaking of the grid blades is arranged on the outer side of the grid connecting plate 1.

[0037] The grid blade includes a blade inner plate 31 and a blade outer plate 32, and the blade inner plate 31 is clamped and connected with the blade outer plate 32.

[0038] The auxiliary heating ice breaking assembly comprises a hot gas input pipe 24 in communication with the limiting rod, a plurality of groups of hot air passing holes 26 are formed in the inner plate 31 of the blade, the plurality of groups of hot air passing holes 26 can make the inside of the blade communicate with each other, the output end of the hot gas input pipe 24 is connected with the inner side of the inner plate 31 of the blade, a horizontal strip blowing pipe 25 is formed in the bottom side wall of the outer plate 32 of the blade, a plurality of groups of hot air outlet channels 27 are formed in the inner wall of the outer plate 32 of the blade, the output end of the hot air outlet channel 27 is in communication with the horizontal strip blowing pipe 25, and the input end of the hot air outlet channel 27 is arranged to face the inner plate 31 of the blade;

[0039] The hot gas enters the inside of the grille blade, the temperature of the outside of the grille blade is increased, the ice block on the outside of the grille blade is melted, and the hot gas in the inside of the grille blade is discharged into the inside of the horizontal strip blowing pipe 25 through the hot air outlet channels 27. The hot gas blown out through the horizontal strip blowing pipe 25 blows against the bottom of the grille blade. The active auxiliary heating grille blade is combined with the passive hot air blowing ice breaking to realize rapid melting of the ice block in a low-temperature environment, clean the deposits in the gaps of the grille blade, and avoid the risk of secondary freezing of the residual water droplets.

[0040] A hot gas pump 21 is fixedly arranged on the outer wall of the grille connecting plate 1. The hot gas pump 21 belongs to the prior art and has the function of conveying hot gas. The output end of the hot gas pump 21 is connected with a penetrating pipe 23. The two sides of the penetrating pipe 23 are in communication with connecting pipes 22. The output end of the connecting pipe 22 is connected with the limiting rod corresponding to the connecting pipe 22. Then the hot air is first conveyed into the two connecting pipes 22 through the penetrating pipe 23, and then enters the inside of the grille blade through the connecting pipes 22.

[0041] An optical icing sensor is embedded in the bottom wall of the outer plate 32 of the blade. The optical icing sensor is in communication connection with a general control platform in the vehicle cabin to form an active air inlet grille icing monitoring system. The optical icing sensor emits infrared light for detecting the reflectivity RIY of the bottom side of the outer plate 32 of the blade and sending the reflectivity RIY to the general control platform.

[0042] The general control platform acquires the reflectivity RIY and compares and analyzes the reflectivity RIY with a threshold value RI in the database of the general control platform.

[0043] If the reflectivity RIY is less than the threshold value RI, it is determined that the icing state exists and an icing action signal is generated.

[0044] It should be noted that the reflectivity of the threshold value RI is set to 80%. The threshold value RI is obtained by simulating the icing conditions such as low temperature and humidity in the laboratory or on site, monitoring the reflectivity change in real time through the sensor, and counting the critical reflectivity when the ice layer is formed.

[0046] After the ice blocks are melted, the inside of the grid blade and the gap are continuously heated and blown, and the hot air blown out of the horizontal strip blowing pipe 25 below the blade outer plate 32 not only can clean the deposits in the gap of the grid blade to avoid affecting the use of the active air inlet grid in the later period, but also can blow the water droplets above the blade outer plate 32 to dry them quickly to avoid the risk of secondary freezing of the residual water droplets.

[0047] If the reflectivity RIY is greater than or equal to the threshold value RI, it is determined that the state is not icing and no signal is generated.

[0050] It should be noted that the grid blade is driven synchronously by the connecting rod system, usually a multi-connecting rod transmission mechanism is used, combined with a driving motor and a linkage device, to realize accurate opening and closing control of the blade, that is, the connecting rod system usually includes a driving motor, a driving connecting rod, a driven connecting rod and a blade shaft, and the blade is connected with the connecting rod system through the shaft to realize opening and closing action.
