Description

Technical Field

[0001] The utility model relates to the technical field of air duct components, in particular to a lightweight air duct component for automobiles. Background Art

[0002] The lightweight of automobiles is to reduce the curb weight of automobiles as much as possible on the premise of ensuring the strength and safety performance of automobiles, so as to improve the power performance of automobiles. Due to the needs of environmental protection and energy conservation, the lightweight of automobiles has become the trend of the development of the world's automobiles. The air ducts on automobiles, including air-conditioning ducts, are pipe systems for air transportation and distribution, and are devices for realizing the refrigeration, heating, ventilation and air purification of the air in the carriage to meet the comfort requirements of people.

[0003] When optimizing the existing lightweight air duct components for automobiles, most of them are reflected in solving or reducing the influence of air leakage on the engine. For example, the Chinese utility model patent with the application number CN201911392892.3 discloses "An air duct component for the crankcase ventilation of an automobile engine". In this device, it includes a ventilation pipe body and a heat preservation sleeve, and also includes a clamp respectively connected with the left end and the right end of the ventilation pipe body, and a bushing connected with the clamp; the inner surface of the heat preservation sleeve is connected with the outer surface of the ventilation pipe body, having good connection tightness, capable of avoiding the phenomenon of the clamp skewing during the assembly process, capable of achieving a good heat preservation effect, ensuring the normal operation of the engine, being convenient to use, and capable of improving the work efficiency of the staff.

[0004] Although the above-mentioned lightweight air duct components for automobiles have certain advantages in solving or reducing the influence of air leakage on the engine, they still have certain disadvantages: since the air duct is a pipe structure and there is air flowing through it inside, at the output end of the air duct, the air flow is likely to cause the pipe to sway, and then lead to the detachment of the connection end of the air duct from the automobile.

[0017] (III) Beneficial effects

[0018] Compared with the prior art, the present utility model provides a lightweight air duct assembly for an automobile, having the following beneficial effects:

[0019] 1. For this lightweight automotive air duct assembly, the entire air duct assembly is placed inside the vehicle. One end of the fan coil unit is connected to the vehicle air conditioning system, and the other end is connected to the interior of the vehicle body, facilitating the flow of air into the vehicle body.

The fan coil unit 2 is wound around the outside of the fan coil frame 4. Both ends of the fan coil frame 4 are connected to the side frame 5. The bottom of the side frame 5 is welded to the support base 6.

[0029] Please refer to Figure 3-4 , a lightweight air duct assembly for automobiles. The pipe stabilizing structure 3 includes a first buckle plate 31, a second buckle plate 32, a surrounding block 33, a matching structure 34, a pin 35, a fastening structure 36 and a connecting block 37. The first buckle plate 31 is arranged opposite to the second buckle plate 32. The first buckle plate 31, the second buckle plate 32 and the surrounding block 33 are connected and installed to each other by bolts. One end of the matching structure 34 is movably engaged with the first buckle plate 31. The other end of the matching structure 34 is hinged and movably matched with the fastening structure 36. The fastening structure 36 passes through the middle of the surrounding block 33. The pin 35 passes through the surrounding block 33. One end of the pin 35 is movably engaged with the inside of the rear end of the fastening structure 36. The connecting block 37 intermittently moves outside the fastening structure 36. The matching structure 34 includes a swing frame a1, a round rod a2, a limiting port a3, a solid block a4 and a clamping block a5. The round rod a2 is fixedly connected to a position below the outer side of the solid block a4. The swing frame a1 is movably matched with the solid block a4 through the round rod a2. The limiting port a3 is an integral structure with the swing frame a1 and is arranged in a penetrating manner. The clamping block a5 is fixedly connected above the solid block a4. The first buckle plate 31 and the second buckle plate 32 are respectively sleeved on the outer periphery of the fan coil unit 2. The clamping block a5 is movably engaged with the inside of the first buckle plate 31. The swing frame a1 makes a fixed-point swing, which is convenient for cooperating with the displacement of the fastening structure 36 and can also snap the clamping block a5 into the first buckle plate 31, strengthening the overall firm installation of the pipe stabilizing structure 3. The fastening structure 36 is movably engaged with the insertion pin port q4. After the fastening structure 36 is snapped into the insertion pin port q4, it can play a role in fixing the position of the fastening structure 36.

[0030] Please refer to Figure 5, A lightweight air duct assembly for automobiles. The fastening structure 36 includes a clamping block q1, a connecting block q2, a displacement block q3, and a pin hole q4. The clamping block q1 is connected to the front end face of the connecting block q2. The displacement block q3 is fixedly connected to the rear of the connecting block q2. The pin hole q4 is an integral structure with the displacement block q3 and is provided at the end position of the displacement block q3. The displacement block q3 passes through the middle of the surrounding block 33. There is a connecting block 37 with a gap outside the connecting block q2. The displacement block q3 is hinged and movably matched with one end of the swing frame a1. The clamping block q1 is made of rubber and has toughness and anti-slip properties.

[0031] In summary, the entire air duct assembly is placed inside the automobile. One end of the fan coil 2 is connected to the automobile air conditioning system 1 and wound around the outside of the fan coil frame 4 to increase the pipe length. The other end of the fan coil 2 is connected to the inside of the automobile body to facilitate the flow of gas into the vehicle body. The pipe stabilizing structure 3 is installed at the edge of the connection end of the fan coil 2 and the automobile, which is convenient for strengthening and stabilizing the position of the fan coil 2 near the connection end. Through the provided matching structure 34, the user puts the first clamping plate 31 and the second clamping plate 32 on the outer periphery of the fan coil 2 respectively, and then, according to the diameter and width of the fan coil 2, horizontally pushes the fastening structure 36 to push the clamping block q1 against the outer peripheral surface of the fan coil 2. During the process of pushing the fastening structure 36, the displacement block q3 moves horizontally, causing the lower end of the swing frame a1 to displace, and the swing frame a1 makes a pivotal swing. The upper end of the swing frame a1 can push the clamping block a5 to displace under the sliding fit of the round rod a2 and the limiting port a3, facilitating the clamping block a5 to be clamped into the first clamping plate 31. When the clamping block q1 is against the outer periphery of the fan coil 2, the connecting block 37 is also displaced due to the shape change of the connecting block q2 and is clamped into the first clamping plate 31 and the second clamping plate 32, which can facilitate the disassembly and assembly of the first clamping plate 31 and the second clamping plate 32 without using bolts for connection. Then, the retaining pin 35 is pushed and pulled so that its outer end is pressed into the pin hole q4 to fix the position of the fastening structure 36. Due to the toughness and anti-slip properties of the clamping block q1 itself, it generates a stabilizing effect on the outer periphery of the fan coil 2, facilitating the overall pipe stabilizing structure 3 to better play a stabilizing effect at the position of the fan coil 2 near the connection end of the vehicle body and avoiding the fan coil 2 from swaying due to the shuttle of the wind, which may cause the connection end of the air duct and the automobile to fall off.
