Description

Technical Field

[0001] This utility model relates to the field of automotive piping technology, and in particular to an automotive air conditioning ventilation defrosting duct assembly. Background Technology

[0002] The "Automotive Air Conditioning Ventilation and Defrosting Duct Assembly" is a core component of the automotive air conditioning system, responsible for air distribution, ventilation, and defrosting. It delivers treated air to different areas of the vehicle through a network of ducts, ensuring passenger comfort and driving safety. The automotive air conditioning ventilation and defrosting duct assembly is the "vascular network" of the air conditioning system, achieving efficient air distribution and directional delivery through precise design. Its performance directly affects in-vehicle comfort, energy efficiency, and driving safety, making it an indispensable core component of modern automobiles.

[0003] While current automotive air conditioning ventilation defrosting ducts on the market can meet the defrosting needs of automobiles, they still have certain drawbacks during use. For example, due to the complexity of the installation area, the ducts inevitably have bends. Reducing the airflow resistance at the bends is a key aspect of optimizing the duct system efficiency and reducing energy consumption. Currently, most bends at the air outlets lack anti-vortex structures, which hinders low-resistance airflow and reduces energy-saving performance. In addition, the ducts are mostly rigid structures, and the mounting heads on both sides cannot be fine-tuned, making subsequent disassembly and installation inconvenient. Overall, their practicality needs to be improved. Utility Model Content

[0004] To address the above issues and overcome the shortcomings of existing technologies, this utility model provides an automotive air conditioning ventilation and defrosting duct assembly that provides anti-vortex functionality at the duct bends, facilitating low-resistance airflow and improving energy efficiency. The technical solution adopted by this utility model to achieve the above objectives is as follows: A car air conditioning ventilation defrosting duct assembly includes: a duct, both ends of which are fixedly connected to joints; a vortex-eliminating unit is provided on the lower outer wall of the duct; the vortex-eliminating unit includes: a port, the port being opened at the bottom of the outer wall of the duct; an arc-shaped block is provided inside the port; an arc-shaped piece is fixedly connected to the lower surface of the arc-shaped block; a sealing ring is fixedly sleeved on the lower outer wall of the arc-shaped block; the sealing ring abuts against the contact surface of the duct; multiple bolts are inserted into the lower surface of the arc-shaped piece; the bolts sequentially pass through the arc-shaped piece and the sealing ring and are threadedly connected to the duct; and multiple raised ribs are fixedly connected to the upper surface of the arc-shaped block.

[0005] Preferably, the outer wall of the pipe is provided with an indicator arrow.

[0006] Preferably, the pipe has a double-section structure, and the two sections of the pipe are connected to each other by a connecting unit. The connecting unit includes a folded pipe, which is fitted between the two sections of the pipe. Both ends of the outer wall of the folded pipe are fitted with pipe clamps. The outer wall of the pipe inside the folded pipe has an annular groove, and the annular groove has a PTFE ring inside.

[0007] Preferably, the end of the pipe facing the outer wall of the folded pipe has an arc-shaped structure.

[0008] Preferably, the two ends of the folded tube are provided with auxiliary units, the auxiliary units including: multiple arc-shaped strips, the multiple arc-shaped strips are respectively fixed to the two ends of the folded tube, the surface of the arc-shaped strips away from the folded tube is magnetically attracted with a magnetic ring, the surface of the magnetic rings away from the arc-shaped strips is fixedly connected with a collar, and the inner wall of the collar is fixedly connected to the pipe.

[0009] Preferably, a pair of insert rods are inserted into the surface of the arc-shaped strip, a portion of which is inserted into the interior of the folded tube, and the insert rods are fixedly connected to the arc-shaped strip and the folded tube.

[0010] Compared with the prior art, the present invention has the following beneficial effects: (1) This utility model uses the cooperation between pipe, joint and anti-vortex unit to first install the pipe into the car air conditioning ventilation defrosting pipe using two joints. When the airflow passes through the pipe bend, the multiple protruding ribs at the top of the arc block can divide the airflow, destroy the vortex core, and accelerate the energy dissipation of the airflow impact, thereby providing anti-vortex function at the air outlet of the pipe bend, facilitating low-resistance airflow passage, and thus improving the energy saving effect. (2) This utility model, through the cooperation between the pipe, the joint, and the connecting unit, since the pipe is a double-section structure and the two sections are connected by a deformable folding pipe, can make fine adjustments at both ends of the pipe during installation or disassembly, which can provide convenience for initial installation and subsequent disassembly, and enhance the practical performance. (3) Through the cooperation between the pipe, joint, connecting unit and auxiliary unit, when the folded pipe is fitted onto the outer wall end of the pipe, the operator can make the arc strip at the end of the folded pipe fit with the magnetic ring. At this time, the magnetic ring can generate an attraction force with the arc strip, which can stabilize the folded pipe after it is fitted. At the same time, the magnetic ring can also limit the end of the folded pipe. When the pipe clamp is used to tighten the outer wall end of the folded pipe later, it can make the PTFE ring inside the ring groove in a tightened state, which is conducive to achieving a high-quality seal between the folded pipe and the pipe.

Detailed Implementation

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0014] Example 1: As Figures 1-4As shown, this utility model provides an automotive air conditioning ventilation and defrosting duct assembly, comprising: a duct 1, which is made of high-strength, corrosion-resistant alloy steel. This material effectively resists corrosion from moisture and chemicals that may exist in the automotive air conditioning system, ensuring that the duct will not rust or corrode during long-term use, thereby extending the service life of the duct. Both ends of the duct 1 are fixedly connected to connectors 2. The connectors 2 are of a standardized design, and their interface dimensions match the standard interface of the automotive air conditioning ventilation and defrosting duct, ensuring a quick and precise connection with the duct. Simultaneously, the connectors... The head 2 is equipped with a sealing gasket to effectively prevent air leakage and ensure the normal operation of the system. A vortex suppression unit is located on the lower outer wall of pipe 1. This unit includes a port 3, which is located at the bottom of the outer wall of pipe 1. The edges of the port 3 are finely ground, resulting in a smooth, burr-free surface to prevent damage to internally installed components. An arc-shaped block 4 is located inside the port 3. This arc-shaped block 4 is made of lightweight, high-strength engineering plastic, ensuring structural strength while reducing overall weight. An arc-shaped piece 5 is fixed to the lower surface of the arc-shaped block 4, and the arc-shaped piece 5 and the arc-shaped block 4 are integrally injection molded. The fabrication process ensures a secure and reliable connection between the two components. A sealing ring 6 is fixedly fitted onto the lower outer wall of the arc-shaped block 4. The sealing ring 6 is made of high-quality rubber material, possessing excellent elasticity and sealing performance. It can tightly fit the inner wall of the pipe 1, preventing airflow leakage from the opening 3. The sealing ring 6 abuts against the contact surface of the pipe 1. Through a special compression structure design, the sealing ring 6 can generate sufficient pressure after installation to ensure a sealing effect. Multiple bolts 7 are inserted into the lower surface of the arc-shaped piece 5. The bolts 7 are made of high-strength stainless steel, possessing corrosion resistance and fatigue resistance properties. The bolts 7 sequentially penetrate the arc-shaped piece. 5 and sealing ring 6 are threaded to pipe 1. During installation, the tightening torque of bolt 7 is precisely controlled to ensure that the connection between the components is tight and stable. Multiple raised ribs 8 are fixed to the upper surface of arc block 4. The raised ribs 8 are streamlined and their height and spacing are carefully calculated and optimized. When the airflow passes through the bend of pipe 1, the multiple raised ribs 8 at the top of arc block 4 can divide the airflow, destroy the vortex core, and accelerate the energy dissipation of the airflow impact, thereby providing a vortex elimination function at the air outlet of pipe 1 bend, facilitating low-resistance airflow passage, and thus improving the energy saving effect.

[0015] Example 2: The outer wall of pipe 1 is provided with an indicator arrow. The indicator arrow is made of high-brightness, wear-resistant fluorescent material and can be clearly seen even in low light conditions. The direction of the indicator arrow clearly indicates the direction of airflow, which makes it convenient for installers to quickly and accurately determine the installation direction of the pipe during the installation process and avoid abnormal system operation caused by incorrect installation direction.

[0016] Example 3: Pipe 1 has a double-section structure, and the two sections of pipe 1 are connected to each other by a connecting unit. The connecting unit includes a folded pipe 9, which adopts a deformable corrugated pipe structure. Its corrugated shape is specially designed to withstand greater pressure and tension while ensuring a certain degree of flexibility. The folded pipe 9 is fitted between the two sections of pipe 1. During installation, the folded pipe 9 can be bent and adjusted to a certain extent according to the actual space and installation requirements. Both ends of the outer wall of the folded pipe 9 are fitted with pipe clamps 10, which are made of stainless steel and have high strength and good corrosion resistance. The pipe clamps 10 are fastened to the folded pipe 10 by bolts. Pipe 9 is tightly connected to pipe 1 to ensure the sealing and stability of the connection. Pipe 1 has an annular groove 11 on the outer wall inside the folded pipe 9. The depth and width of the annular groove 11 are precisely calculated to provide suitable installation space for the PTFE ring 12. The PTFE ring 12 is installed inside the annular groove 11. The PTFE ring 12 has excellent high temperature resistance, corrosion resistance and self-lubricating properties, and can maintain a good sealing effect in harsh environments such as high temperature and humidity. When the pipe clamp 10 is used to tighten the end of the outer wall of the folded pipe 9, it is easy to keep the PTFE ring 12 inside the annular groove 11 in a tightened state, which is conducive to achieving a high-quality seal between the folded pipe 9 and pipe 1.

[0017] Example 4: The end of pipe 1 facing the outer wall of folded pipe 9 has an arc-shaped structure, which makes it easy for folded pipe 9 to be fitted onto the outer wall of pipe 1.

[0018] Example 5: The two ends of the folded tube 9 are provided with auxiliary units, each including multiple arc-shaped strips 13. These arc-shaped strips 13 are respectively fixed to both ends of the folded tube 9. The arc-shaped strips 13 are made of galvanized iron. Magnetic rings 14 are magnetically attracted to the surface of the arc-shaped strips 13 away from the folded tube 9. The magnetic rings 14 are made of a strong magnetic material, capable of generating sufficient magnetic force to ensure a tight attraction with the arc-shaped strips 13. A collar 15 is fixed to the surface of the magnetic ring 14 away from the arc-shaped strips 13. The collar 15 is made of metal. The inner wall of the collar 15 is fixedly connected to the pipe 1 by welding. During installation, the folded pipe 9 is first fitted onto the outer end of the pipe 1, so that the arc strip 13 at the end of the folded pipe 9 fits against the magnetic ring 14. At this time, the magnetic ring 14 can generate an attraction force with the arc strip 13, which can stabilize the fitted folded pipe 9. At the same time, the magnetic ring 14 can also limit the end of the folded pipe 9 to prevent the folded pipe 9 from shifting during use.

[0019] Example 6: A pair of insert rods 16 are inserted into the surface of the arc-shaped strip 13. The insert rods 16 are made of high-strength alloy steel and have sufficient hardness and strength. A part of the insert rods 16 is inserted into the interior of the folded tube 9. The insert rods 16 are fixedly connected to the arc-shaped strip 13 and the folded tube 9 by welding or riveting. This further enhances the connection stability between the folded tube 9 and the pipe 1, ensuring that the pipe assembly will not loosen or fall off due to vibration or other reasons during vehicle operation.

[0020] In use, first, fit the folded tube 9 onto the outer end of the pipe 1, so that the arc-shaped strip 13 at the end of the folded tube 9 fits against the magnetic ring 14. At this time, the magnetic ring 14 can generate an attraction force with the arc-shaped strip 13, which has a stabilizing effect on the fitted folded tube 9. At the same time, the magnetic ring 14 can also limit the end of the folded tube 9. When the pipe clamp 10 is used to tighten the outer end of the folded tube 9, it can facilitate the PTFE ring 12 inside the ring groove 11 to be in a tightened state, which is conducive to achieving a good seal between the folded tube 9 and the pipe 1. Then, use the two connectors 2 to install the pipe 1 onto the car. In the air conditioning ventilation defrosting duct, when the airflow passes through the bend of duct 1, the multiple protruding ribs 8 at the top of the arc-shaped block 4 can divide the airflow, destroy the vortex core, and accelerate the energy dissipation of the airflow impact, thereby providing a vortex-eliminating function at the air outlet of the bend of duct 1, facilitating low-resistance airflow passage, and thus improving energy-saving effect. Since duct 1 has a double-section structure, and the two sections are connected by a deformable folding tube 9, the joints 2 at both ends of duct 1 can be finely adjusted during installation or disassembly, which can facilitate initial installation and subsequent disassembly, enhancing practicality. The above embodiment is only one of the preferred embodiments of this utility model and should not be used to limit the protection scope of this utility model. Any modifications or refinements made to the main design concept and spirit of this utility model that are not substantial in nature, but solve the same technical problem as this utility model, should be included within the protection scope of this utility model.
