[0003] The defrosting structure of a car is to blow the heat generated by the engine through a blower and blow it into the car and onto the car's windshield along the car's air duct, thereby raising the temperature inside the car and preventing the car's windshield from frosting and affecting driving safety.

[0004] The existing automobile defrost duct structure is usually arranged under the dashboard. However, since the dashboard is often equipped with more circuits and various brackets, the space under the dashboard is limited. The defrost duct and other piping structures are prone to aging and damage during long-term use and under high temperature, which causes many inconveniences in the installation of the defrost duct.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] Reference Figure 1-Figure 5 A car defrosting air duct structure that is easy to assemble includes an instrument panel 1, a rectangular groove 2 is opened on one side of the instrument panel 1, and a plurality of groups of air outlets arranged at intervals are arranged in the rectangular groove 2, each group of air outlets is composed of a plurality of through holes 3 arranged at intervals, and is used to discharge hot air to act on the windshield in the car.

[0029] A wind shield 8 is provided below each set of air outlets, a limited skirt 9 is installed along the top of the wind shield 8, and an air inlet pipeline is connected to the bottom of the wind shield 8;

[0030] A first support plate 4 having two ends bent in an "L" shape is provided below each group of air outlets, and a first limiting plate 5 having two ends bent in an "L" shape is vertically installed at the bottom of the first support plate 4. The first limiting plate 5 corresponds to the first support plate 4, forming a bearing member with a cross-section of L, and the inner limiting skirt 9 of the first support plate 4 corresponds to allow the limiting skirt 9 of the wind cover 8 to be cured in the first support plate 4, so that the wind cover 8 is hung below the air outlet, that is, when installing the wind cover 8, the wind cover 8 can be directly inserted below the air outlet by pushing, and because the first limiting plate 5 wraps and supports the bottom of the limiting skirt 9, the wind cover 8 can be stabilized below the air outlet.

[0031] like Figure 2 As shown, at least two spaced apart limiting holes 6 are provided on the outer walls on both sides of the first support plate 4 near the opening end, the limiting holes 6 are semicircular grooves, and a slide groove 7 is also provided on the outer wall of the first support plate 4, the slide groove 7 passes through the middle of the limiting holes 6, and the slide groove 7 passes through the end of the first support plate 4 near the opening;

[0032] like Figure 1 and Figure 4 As shown, a second support plate 11 with two ends bent in an "L" shape is provided below one side of the opening of the first support plate 4, the second support plate 11 corresponds to the bottom position of the opening of the first support plate 4, and second limiting plates 12 are vertically installed on the top of both ends of the second support plate 11, and the second limiting plates 12 correspond to the outer wall of the first support plate 4. When the second support plate 11 is placed at the bottom of the first limiting plate 5, the second limiting plate 12 will be attached to the outer wall of the first support plate 4, thereby wrapping the side of the limiting skirt 9 away from the first support plate 4;

[0033] As the second support plate 11 moves toward the first support plate 4, a baffle 18 is vertically installed on the top of the second support plate 11 away from the first support plate 4. The first support plate 4 will abut against the baffle 18, thereby limiting the moving distance of the second support plate 11 and cooperating with the first support plate 4 to completely wrap the limiting skirt 9.

[0034] At least two cylinders 13 are vertically installed on the outer side of the second limiting plate 12, and a circular groove 14 corresponding to the cylinder 13 is opened on the second limiting plate 12, and a columnar block 15 is arranged in the circular groove 14, and the columnar block 15 corresponds to the limiting hole 6. A compression spring 17 is arranged in the cylinder 13, and one end of the compression spring 17 is fixed on the columnar block 15, and the other end of the compression spring 17 is fixed on the end of the cylinder 13. With the movement of the second support plate 11, the columnar block 15 will be placed in the slide groove 7, and under the pressure of the inner wall of the slide groove 7 , so that the columnar block 15 is retracted into the cylinder 13, and because the end of the slide groove 7 is provided with an arc section, the columnar block 15 can contact the slide groove 7 so that the inner wall of the slide groove 7 can better push the columnar block 15. With the continued movement of the second support plate 11, the columnar block 15 will move to the limiting hole 6, and the depth of the limiting hole 6 is greater than the slide groove 7, so that the columnar block 15 is pushed to the limiting hole 6 under the elastic force of the compression spring 17, so that the second support plate 11 is fixed on the first support plate 4, and the wind cover 8 is fixed below the air outlet.

[0035] In order to prevent the cylindrical block 15 from popping out of the cylinder 13 due to the elastic force of the compression spring 17, the radius of the circular groove 14 is smaller than the inner diameter of the cylinder 13, and a disc 16 is coaxially installed at one end of the cylindrical block 15 close to the compression spring 17. The side of the disc 16 is matched with the inner wall clearance of the cylinder 13, so that when the cylindrical block 15 moves toward the end away from the compression spring 17 under the elastic force of the compression spring 17, the disc 16 will abut against the end of the cylinder 13, thereby limiting the movement of the cylindrical block 15 and limiting the maximum moving distance of the cylindrical block 15, so that it will not escape from the cylinder 13.

[0036] After the wind shield 8 is installed, Figure 1 and Figure 2 As shown, the air inlet pipeline includes a multi-way pipe 22, and a connecting pipe 20 is rotatably installed on the branch pipe of the multi-way pipe 22. The top of the connecting pipe 20 is threadedly connected to the sleeve 19, and the top of the sleeve 19 is connected to the bottom of the wind hood 8. The connecting pipe 20 can be taken and extended to the bottom of the sleeve 19, and the connecting pipe 20 is rotated, so that the connecting pipe 20 can be threadedly connected to the bottom of the sleeve 19. The rotatable connection between the connecting pipe 20 and the multi-way pipe 22 allows multiple connecting pipes 20 to be connected one by one without obstruction.

[0037] When the connecting pipe 20 is connected, an annular seat 21 is coaxially installed on the connecting pipe 20. The annular seat 21 corresponds to the bottom of the sleeve 19. The bottom of the sleeve 19 will abut against the annular seat 21, so as to limit the installation of the connecting pipe 20. A sealing ring is coaxially arranged on the top of the annular seat 21. The sealing ring is elastic, so as to ensure the sealing of the connection between the sleeve 19 and the connecting pipe 20 and improve the tightness of the threaded connection due to the elastic effect of the sealing ring.

[0038] Specifically, in actual use, the main pipe of the multi-way pipe 22 is connected to the blower, and the blower sends the heat generated by the generator and other equipment to the wind hood 8. Since a plurality of spaced-apart guide plates 10 are provided in the wind hood 8, and the top of the guide plate 10 corresponds to the position of two adjacent through holes 3, the hot air can be evenly sent to each through hole 3, making the hot air discharged from the through hole 3 more uniform, which helps to better perform the defrosting operation.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
