It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0024] A defrosting air duct for a car instrument panel, as shown in the attached Figure 1-6 As shown, it includes an instrument panel shell 1 and an air outlet duct 6, an instrument panel body 2 is installed on the front of the instrument panel shell 1, a warm air channel slide 3 is opened inside the instrument panel shell 1, a warm air channel tube 4 is movably inserted inside the warm air channel slide 3, one end of the warm air channel tube 4 is fixedly connected to an air source pipe 5, the other end of the warm air channel tube 4 is fixedly connected to an air guide hose 7, the end of the air guide hose 7 away from the warm air channel tube 4 is fixedly inserted inside the air outlet duct 6, and an angle changing component 8 is arranged between the air outlet duct 6 and the warm air channel tube 4; there are two warm air channel slides 3, and the two warm air channel slides 3 are symmetrical about the instrument panel body 2. When the instrument panel body 2 is defrosted, the hot air will enter the interior of the air outlet duct 6 through the air source pipe 5, the warm air channel tube 4 and the air guide hose 7 in sequence, and then be sprayed on the instrument panel body 2 through the air outlet of the air outlet duct 6 to defrost the instrument panel body 2.

[0025] A first ring 9 is fixedly connected to the outer surface of the warm air channel tube 4, and the first ring 9 is slidably connected to the inside of the warm air channel chute 3, and a second ring 10 is fixedly connected to the inside of the warm air channel chute 3. An electric push rod 11 is installed on the side of the second ring 10 close to the first ring 9, and the telescopic end of the electric push rod 11 is fixedly connected to the first ring 9; when the electric push rod 11 is started, the electric push rod 11 can drive the first ring 9 to slide inside the warm air channel chute 3, and the movement of the first ring 9 can drive the warm air channel tube 4 and the air outlet pipe 6 to move accordingly.

[0026] The angle change component 8 includes two circular plates 801, and the two circular plates 801 are fixedly connected to the outer surface of the warm air duct tube 4 near one end of the air outlet duct 6, and the two circular plates 801 are symmetrical about the warm air duct tube 4. The two circular plates 801 are fixedly connected with a rotating shaft 802 on one side away from the warm air duct tube 4, and the outer surface of the air outlet duct 6 near one end of the warm air duct tube 4 is fixedly connected with two symmetrical right-angle plates 803, and the ends of the two rotating shafts 802 away from each other respectively penetrate the two right-angle plates 803 and extend to the outside of the two right-angle plates 803, and the inside of the right-angle plates 803 is provided with a through hole compatible with the rotating shaft 802, and the air outlet duct 6 and the two right-angle plates 803 can rotate along the two rotating shafts 802.

[0027] The ends of the two rotating shafts 802 that are away from each other are fixedly connected with a blocking cylinder 804, and the ends of the two blocking cylinders 804 that are close to each other are respectively abutted against the two right-angle plates 803, and the ends of the two right-angle plates 803 that are away from each other are fixed with a torsion spring 805, and the ends of the two torsion springs 805 that are away from the two right-angle plates 803 are respectively fixedly connected with the two blocking cylinders 804; when the torsion spring 805 is in a normal state, the angle between the air outlet duct 6 and the warm air channel duct 4 is sixty degrees. At this time, the air outlet of the air outlet duct 6 located outside the warm air channel slide groove 3 will face the instrument panel body 2. When the angle of the air outlet duct 6 is changed, the torsion spring 805 will be deformed.

[0028] Working principle: When the instrument panel body 2 is defrosted, the electric push rod 11 is first started, so that the electric push rod 11 drives the first ring 9 and the air outlet pipe 6 to move in the direction away from the second ring 10. When the first ring 9 moves to the maximum distance in the direction away from the second ring 10, the air outlet pipe 6 will be completely moved out from the inside of the warm air channel slide 3. At this time, under the action of the torsion spring 805, the air outlet pipe 6 will automatically rotate to an angle of sixty degrees with the warm air channel pipe 4. At this time, the air outlet of the air outlet pipe 6 will face the instrument panel body 2, and then the hot air will pass through the wind source pipe 5, the warm air channel pipe 4 and the air guide hose 7 in turn into the inside of the air outlet pipe 6, and then sprayed on the instrument panel body 2 through the air outlet of the air outlet pipe 6. The instrument panel body 2 can be defrosted. After defrosting is completed, the electric push rod 11 is started to drive the first ring 9 and the air outlet pipe 6 to move in the direction of the second ring 10. During the movement of the air outlet pipe 6, the inner wall of the warm air channel chute 3 will block the air outlet pipe 6, so that the angle between the air outlet pipe 6 and the warm air channel pipe 4 will become larger. During the change of the angle between the air outlet pipe 6 and the warm air channel pipe 4, the torsion spring 805 will be deformed. When the first ring 9 moves to the maximum distance in the direction of the second ring 10, the air outlet pipe 6 will be completely moved to the inside of the warm air channel chute 3. At this time, the air outlet pipe 6 is stored, thereby achieving the effect of the air outlet pipe 6 freely entering and exiting the instrument panel housing 1.
