[0028] [First embodiment]

[0029] Refer to Figures 1-4As shown in the figure, a vehicle interior heat dissipation air duct disclosed in the first embodiment of the present utility model includes an air duct pipe 1. A support device 2 is arranged inside the air duct pipe 1, and a protection device 3 is arranged outside the air duct pipe 1. By providing the support device, the inside of the air duct pipe can be supported and strengthened from the inside out, further improving the internal strength and service life of the hollow-structured air duct pipe, and ensuring the normal flow of air inside the air duct pipe. By providing the protection device, when a person or an object may accidentally collide with the heat dissipation air duct during driving conditions such as bumps or sudden brakes during vehicle driving, the person or object is intercepted by the protection plate, and the impact force is effectively buffered, completing the protection of the air duct pipe and ensuring the normal flow of air inside the air duct pipe.

[0030] As Figures 1-2 shown, the support device 2 provided in this embodiment includes a rectangular rod 21 fixed inside the air duct pipe 1. Both ends of the rectangular rod 21 are fixedly connected with support plates 22, and the outer wall of the support plate 22 is fixedly connected with the inner wall of the air duct pipe 1. By the support plate 22, the contact area with the inner wall of the air duct pipe 1 is increased, thereby increasing the support stability. A circular hole 23 is opened inside the rectangular rod 21 to allow the air inside the air duct pipe 1 to flow. By providing the support device, the rectangular rod and the support plate are fixed inside the air duct pipe, so that the rectangular rod cooperates with the support plate to support the inside of the air duct pipe from the inside out, further improving the internal strength and service life of the hollow-structured air duct pipe, and ensuring the normal flow of air inside the air duct pipe.

[0031] Preferably, as Figure 2 shown, a plurality of reinforcing blocks 25 are fixedly arranged inside the rectangular rod 21. The plurality of reinforcing blocks 25 are arranged at equal intervals. By providing the reinforcing blocks, the reinforcing blocks can assist in reinforcing the rectangular rod and can also assist in supporting the rectangular rod, improving the strength of the rectangular rod and reducing the possibility of the rectangular rod bending. Flow holes 26 are opened inside each of the plurality of reinforcing blocks 25. By providing the flow holes, the air flowing inside the air duct pipe can achieve internal circulation through the flow holes, avoiding the reinforcing blocks from obstructing the normal flow of the air inside the air duct pipe. The flow holes 26 can be set to corresponding shapes according to actual needs. For example, in this embodiment, they are set as rectangular holes, which facilitate processing and increase the internal air flow rate. In addition, a plurality of auxiliary holes 24 are opened on one side of the rectangular rod 21, and the plurality of auxiliary holes 24 are communicated with the flow holes 26. By providing the auxiliary holes, the air flowing inside the air duct pipe can enter the inside of the flow holes through the plurality of auxiliary holes and be discharged from the other side, improving the fluidity and exchange efficiency of the air inside the air duct pipe.

[0032] As Figure 2As shown in the figure, a plurality of support rods 27 are fixedly connected to the outer edge of the support plate 22. The plurality of support rods 27 are all fixedly connected to the inner wall of the air duct 1. The plurality of support rods 27 are arranged at equal intervals, and the extending direction of the support rods 27 matches the shape of the air duct 1. The adjacent support plates 22 are fixedly connected through the plurality of support rods 27. At the same time, the plurality of support rods can increase the supporting area of the inner wall of the air duct, further improving the supporting effect on the air duct.

[0033] As Figures 3-4 shown, the protection device 3 in this embodiment includes a rectangular cylinder 31. The rectangular cylinder 31 is fixedly connected to the outer wall of the air duct 1. A circular through hole 32 is opened inside the rectangular cylinder 31. A rubber pad 33 is fixed to the bottom of the inner wall of the rectangular cylinder 31. A round rod 34 is slidably connected to the inner wall of the circular through hole 32. One end of the round rod 34 away from the rubber pad 33 is fixedly connected to a protection plate 35. By providing the protection device, when the vehicle is driving and there may be accidental collisions of personnel or objects with the heat dissipation air duct during bumpy or sudden braking and other driving conditions, the personnel or objects are intercepted by the protection plate, and the impact force is effectively buffered to complete the protection of the air duct, ensuring the normal flow of air inside the air duct.

[0034] As a preference of this embodiment, a plurality of convex strips 37 are fixedly connected to the surface of the protection plate 35. The plurality of convex strips 37 are arranged at equal distances. By providing the convex strips, the convex strips can separate the object from the protection plate, reducing the wear on the surface of the protection plate when the object contacts it; in addition, one end of the round rod 34 close to the rubber pad 33 is fixedly connected to a rectangular plate 36. The outer edge of the rectangular plate 36 is slidably connected to the inner wall of the rectangular cylinder 31. The rectangular plate can increase the contact area between the round rod and the rubber pad, thereby improving the buffering effect. At the same time, the cross-sectional dimension of the rectangular plate is larger than the inner diameter of the circular through hole 32, so as to ensure that the round rod 34 is located inside the circular through hole 32 and prevent it from unexpectedly coming out of the circular through hole 32.

[0035] The specific working process of this embodiment is as follows:

[0036] First, the rectangular rod 21 and the support plate 22 are fixed inside the air duct 1, so that the rectangular rod 21 cooperates with the support plate 22 to support the inside of the air duct 1 from the inside to the outside, further improving the internal strength and service life of the hollow-structured air duct, and ensuring the normal flow of air inside the air duct.

[0037] When an external object is about to collide with the surface of the air duct 1, the object is intercepted by the protection plate 35. When the protection plate 35 is subjected to an impact force, it moves towards the direction close to the rectangular cylinder 31, so that the protection plate 35 drives the round rod 34 to move along the inside of the circular through hole 32 towards the direction close to the inside of the rectangular cylinder 31. At the same time, the round rod 34 squeezes the rubber pad 33 inside the rectangular cylinder 31, and the impact force brought by the round rod 34 is reduced through the rubber pad 33, thereby completing the protection of the air duct 1.

[0038] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in any other form. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as they do not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still belong to the protection scope of the technical solution of the present utility model. In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood through specific situations.
