Technical Field
[0001] This utility model relates to the field of air ducts, and in particular to a novel automotive air duct structure. Background Technology
[0002] Automotive air duct structure refers to the pipes and ventilation systems used to guide air to different parts of a car. The main purpose is to optimize engine cooling, air circulation inside the vehicle, and airflow to other parts of the vehicle body.
[0003] When air circulates inside a car, it is guided to various areas through air ducts to achieve air circulation. However, the ductwork is prone to deformation under stress, causing the inner walls to stick together and reducing ventilation efficiency, thus affecting the effectiveness of the air duct system. Utility Model Content
[0004] The technical problem this invention aims to solve is that when the duct body is in use, it is prone to deformation under stress, causing the inner walls on both sides to stick together, which reduces the ventilation effect and thus affects the performance of the duct.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a novel automotive air duct structure, including a pipe body, wherein a support device is provided inside the pipe body, and the support device supports the inside of the pipe body through a first support plate and a second support plate.
[0006] The effect achieved by the above components is as follows: when air circulates inside the car, the air inside the car is guided to various areas through the air ducts to complete the air circulation inside the car. When using the air ducts, a support device is used to support and reinforce the inside of the car's air duct.
[0007] Preferably, the support device includes a first support plate, a placement block, a bolt, an adjusting block, an adjusting groove formed on the adjusting block, and a second support plate. The first support plate is disposed on the inner wall of the pipe body, the placement block is located on one side of the first support plate, the adjusting block slides inside the placement block and drives the second support plate to move, the bolt is inserted inside the placement block and reaches the adjusting groove on one side of the adjusting block, and the second support plate abuts against the pipe body.
[0008] The effect achieved by the above components is as follows: When using the support device, the first support plate and the second support plate are placed inside the pipe body, and then the first support plate and the second support plate are moved away from each other. At this time, the adjusting block fixed on one side of the second support plate will slide inside the placement block fixed on the first support plate. Then the first support plate and the second support plate abut against the inner wall of the pipe body. Then the bolt is rotated so that the bolt passes through the adjusting groove on one side of the placement block and the adjusting block for threaded fixation. Then the installation and fixation of the first support plate and the second support plate inside the pipe body is completed, so that the first support plate and the second support plate support and reinforce the inside of the pipe body. By using the support device, the inside of the automotive air duct can be supported and reinforced, avoiding deformation of the pipe body after being subjected to force, which would cause the inner walls on both sides to stick together and affect the ventilation effect, thereby improving the use effect of the air duct.
[0009] Preferably, the first support plate and the second support plate are provided with rubber pads on opposite sides, and the rubber pads increase the friction between the first support plate and the second support plate and the inner wall of the tube.
[0010] The effect achieved by the above components is as follows: by fixing the rubber pad to the first support plate and the second support plate on one side away from each other, the friction between the first support plate and the second support plate and the pipe body is increased, thereby enabling the first support plate and the second support plate to better abut and fix with the pipe body.
[0011] Preferably, both sides of the first support plate and the second support plate are provided with extension plates, which increase the area of the first support plate and the second support plate.
[0012] The effect achieved by the above components is that by fixing extension plates on both sides of the first and second support plates, the first and second support plates can support the four walls inside the tube, thereby improving the performance of the first and second support plates.
[0013] Preferably, the placement block is provided with guide plates on both sides, which guide and disperse the air.
[0014] The effect achieved by the above components is that by fixing guide plates on both sides of the placement block, the airflow is quickly guided and dispersed when it reaches the placement block, thereby improving the use effect of the placement block.
[0015] Preferably, a washer is provided on one side of the bolt to increase the contact area between the bolt and the placement block.
[0016] The effect achieved by the above components is as follows: the bolts and washers are abutted together to fix the bolts, thereby increasing the contact area between the bolts and the placement block, and thus making the bolts more firmly fix the position of the adjustment block.
[0017] Preferably, a groove is formed on one side of the bolt, which facilitates tool docking.
[0018] The effect achieved by the above-mentioned components is that by creating a groove on one side of the bolt, tools such as screwdrivers can quickly engage with the bolt, thereby allowing the bolt to rotate more easily.
[0019] Preferably, the placement block has arc-shaped strips on both sides inside, and the arc surface of the arc-shaped strips is close to the adjustment block.
[0020] The effect achieved by the above components is as follows: by fixing the arc strip inside the placement block, the contact area between the placement block and the adjustment block is reduced, thereby reducing the friction between the two and making it easier for the adjustment block to slide inside the placement block.
[0021] In summary, the beneficial effects of this utility model are as follows:
[0022] By using a support device, the interior of the automotive air duct can be reinforced to prevent deformation under stress, which could cause the inner walls on both sides to stick together and affect ventilation, thus improving the performance of the air duct. Attached Figure Description

These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" or "linked" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0031] Figures 1 to 4 The diagram illustrates a novel automotive air duct structure, comprising a duct body 1. An internal support device 2 is provided within the duct body 1. The support device 2 supports the interior of the duct body 1 via a first support plate 21 and a second support plate 26. During air circulation within the vehicle, the air is guided to various areas through the air duct, thus completing the airflow within the vehicle. Furthermore, the support device 2 reinforces and supports the interior of the duct body 1 during the use of the air duct.
[0032] Figures 1 to 4 The support device 2 shown includes a first support plate 21, a placement block 22, a bolt 23, an adjusting block 24, an adjusting groove 25 opened on the adjusting block 24, and a second support plate 26. The first support plate 21 is disposed on the inner wall of the pipe body 1. The placement block 22 is located on one side of the first support plate 21. The adjusting block 24 slides inside the placement block 22 and drives the second support plate 26 to move. The bolt 23 is inserted inside the placement block 22 and reaches the adjusting groove 25 on one side of the adjusting block 24. The second support plate 26 abuts against the pipe body 1. When using the support device 2, the first support plate 21 and the second support plate 26 are placed inside the pipe body 1, and then the first support plate 21 and the second support plate 26 are moved away from each other. At this time, the adjusting block 24 fixed on one side of the second support plate 26 will slide inside the placement block 22 fixed on the first support plate 21. Then the first support plate 21 and the second support plate 26 abut against the inner wall of the pipe body 1. Then the bolt 23 is rotated so that the bolt 23 passes through the adjustment groove 25 on one side of the placement block 22 and the adjusting block 24 and is threadedly fixed. Then the installation and fixing of the first support plate 21 and the second support plate 26 inside the pipe body 1 is completed, so that the first support plate 21 and the second support plate 26 support and reinforce the inside of the pipe body 1. By using the support device 2, the inside of the pipe body 1 of the automotive air duct can be supported and reinforced, so as to avoid the pipe body 1 from deforming under force, which would cause the inner walls on both sides to stick together and affect the ventilation effect, thereby improving the use effect of the air duct.
[0033] Figures 1 to 4Rubber pads 27 are provided on the opposite sides of the first support plate 21 and the second support plate 26, increasing the friction between the first and second support plates 21 and the inner wall of the pipe body 1. By fixing the rubber pads 27 to the opposite sides of the first and second support plates 21 and 26, the friction between the first and second support plates 21 and 26 and the pipe body 1 is increased, thus ensuring better contact and fixation between the first and second support plates 21 and 26 and the pipe body 1. Extension plates 28 are provided on both sides of the first and second support plates 21 and 26, increasing their surface area. By fixing extension plates 28 to both sides of the first and second support plates 21 and 26, the first and second support plates 21 and 26 can support all four walls of the inner wall of the pipe body 1, thereby improving the usability of the first and second support plates 21 and 26.
[0034] Figures 1 to 4 The placement block 22 shown has guide plates 29 on both sides, which guide and disperse the airflow. By fixing the guide plates 29 to both sides of the placement block 22, the airflow is quickly guided and dispersed when it reaches the placement block 22, thereby improving the performance of the placement block 22. A washer 210 is provided on one side of the bolt 23 to increase the contact area between the bolt 23 and the placement block 22. The bolt 23 is fixed by abutting against the washer 210, which increases the contact area between the bolt 23 and the placement block 22, thus making the bolt 23 more firmly fixed in position to the adjusting block 24.
[0035] Figures 1 to 4 The bolt 23 shown has a groove 211 on one side, which facilitates tool engagement. This groove allows screwdrivers and other tools to quickly engage with the bolt 23, enabling better rotation. The placement block 22 has arc-shaped strips 212 on both sides inside, with the arc surfaces of the strips 212 close to the adjusting block 24. These arc-shaped strips 212, fixed inside the placement block 22, reduce the contact area between the placement block 22 and the adjusting block 24, decreasing friction and making it easier for the adjusting block 24 to slide within the placement block 22.
[0036] Working principle: When air circulates inside the car, it is guided to various areas through the air duct to complete the air circulation inside the car. When using the air duct, the support device 2 is used to support and reinforce the inside of the car air duct 1. When using the support device 2, the first support plate 21 and the second support plate 26 are placed inside the pipe body 1, and then the first support plate 21 and the second support plate 26 are moved away from each other. At this time, the adjusting block 24 fixed on one side of the second support plate 26 will slide inside the placement block 22 fixed on the first support plate 21. Then the first support plate 21 and the second support plate 26 abut against the inner wall of the pipe body 1. Then the bolt 23 is rotated so that the bolt 23 passes through the adjustment groove 25 on one side of the placement block 22 and the adjusting block 24 and is threadedly fixed. Then the installation and fixing of the first support plate 21 and the second support plate 26 inside the pipe body 1 is completed, so that the first support plate 21 and the second support plate 26 support and reinforce the inside of the pipe body 1. By using the support device 2, the inside of the pipe body 1 of the automotive air duct can be supported and reinforced, so as to avoid the pipe body 1 from deforming under force, which would cause the inner walls on both sides to stick together and affect the ventilation effect, thereby improving the use effect of the air duct.
