Description

Technical Field

[0001] The utility model specifically relates to a high temperature resistant wind control baffle assembly of an automobile air conditioning system. Background Art

[0002] The wind control baffle of automobile air conditioner refers to the adjustable baffle located at the air outlet of the air conditioner inside the car. It is mainly used to adjust the direction and intensity of the air outlet of the air conditioner to meet the comfort needs of passengers. Since the working conditions of the vehicle are complex during use, it often experiences various extremely harsh environments such as wind, frost, rain, snow, sand and dust, which will have higher requirements for the wind control baffle components. The existing wind control baffle structure generally controls the wind through a composite PP material frame + TPV external sealing structure, is installed in the air duct of the air conditioner, and then connected to the air volume controller of the air outlet of the air conditioner in the car to control the air volume and temperature.

[0003] Since the air conditioning system of new energy electric vehicles uses electric heating, the temperature rises quickly and the temperature is high (the air outlet is greater than 160°C), causing the TPV (thermoplastic vulcanized rubber) wind control baffle to melt and deform after working continuously in a high temperature environment for a period of time, causing the air conditioning wind control baffle to lose its sealing and air volume control function, making the air conditioning air volume and the temperature inside the car uncontrollable. At the same time, due to the use of TPV materials, after long-term use, the TPV material wind control baffle and the air conditioning shell will be damaged by friction, and there will be a risk of wind control baffle adjustment failure or blockage, and at the same time, it will cause air leakage in the air ducts of the air conditioning shell, cross-wind problems, and poor use effect. For this reason, we propose a high-temperature resistant wind control baffle component for automotive air conditioning systems. Utility Model Content

[0004] The utility model aims to provide a high temperature resistant wind control baffle assembly for an automobile air conditioning system, so as to solve the problems of high temperature deformation and poor wear resistance of the wind control baffle proposed in the above background technology.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a high temperature resistant wind control baffle assembly of an automobile air conditioning system, comprising:

[0010] Preferably, the frame is provided with grooves, and a plurality of the grooves are evenly distributed along the axial direction of the frame.

[0014] Preferably, the upper and lower surfaces of the high temperature resistant rubber sleeve expand outward to form a sealing ring sleeve surrounding the frame, and the outer diameter of one end of the sealing ring sleeve away from the frame is larger than the outer diameter of the other opposite end.

[0015] Preferably, the high temperature resistant rubber sleeve is made of silicone rubber or fluororubber.

[0016] Preferably, one end of the plate protrudes outward to form a connecting protrusion, and the inner surface of the high temperature resistant rubber sleeve is provided with a connecting groove that cooperates with the connecting protrusion.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] This patent is provided with a frame, plates and high-temperature resistant rubber sleeves to prevent traditional materials from melting and deforming due to high temperatures, which may cause wind control adjustment failure or jamming. This device has good high-temperature resistance, good strength and high wear resistance, which facilitates the long-term and stable operation of the air conditioner.

[0027] The windshield 1 for adjusting the air volume and the high temperature resistant rubber sleeve 2 arranged on the edge of the windshield 1 ensure that the wind control baffle is continuously sealed at both ends during the rotation process in the shell, ensuring that there is no cross-wind between the left and right air ducts, and by using high temperature resistant rubber, it is easy to avoid melting and deformation due to the high temperature of the air conditioner;
