Description
Technical Field
[0001] This utility model relates to the field of automotive air conditioning technology, and more specifically, to an air outlet structure for an air conditioning device. Background Technology
[0002] In existing automotive air conditioning systems, the air ducts, as key components that transport cool or warm air from the air conditioning unit to various air vents within the vehicle, are typically designed with a fixed installation. These ducts are installed and fixed in concealed locations such as inside the dashboard, behind the center console, under the seats, or inside the headliner during vehicle manufacturing. They are securely attached to the body panels and frame using bolts, clips, or adhesives. While this fixed design ensures that the air ducts will not loosen or detach due to vibration or bumps during vehicle operation, guaranteeing the stability and sealing of the air conditioning system, it also presents challenges for subsequent cleaning and maintenance. Due to the long-term use of vehicle air conditioning systems, a large amount of dust particles, fibrous material, pollen, dander, smoke residue, and oily pollutants from the air gradually accumulate on the inner wall of the air duct. These pollutants form a thick layer of dirt on the inner wall of the air duct, which not only seriously hinders the normal flow of air and reduces the air supply efficiency and cooling and heating effect of the air conditioning system, but more seriously, in a warm and humid environment, this dirt becomes a breeding ground for bacteria, mold, mites and other microorganisms. When the air conditioning system is running, it blows these pathogenic microorganisms and harmful substances into the car with the airflow, seriously polluting the air quality inside the car and posing a direct threat to the respiratory health of the driver and passengers. Utility Model Content
[0003] (a) Technical problems to be solved In view of the problems existing in the prior art, this utility model provides an air outlet structure for an air conditioning device to solve the technical problems mentioned in the background art.
[0004] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: An air outlet structure for an air conditioning device includes a mounting cylinder with an inner sleeve on its inner sidewall. Multiple sets of retaining springs are also cross-arranged on the inner sidewall of the mounting cylinder, with the retaining springs located on one side of the inner sleeve. The device also includes a disassembly / assembly mechanism, which includes an adjusting cylinder rotatably connected to the inner sidewall of the inner sleeve. One end of the adjusting cylinder is connected to a rotating sleeve, and the other end is connected to a retaining ring. The sidewall of the retaining ring rotatably abuts against the sidewall of the inner sleeve. Multiple sets of slots are formed on the inner sidewall of the adjusting cylinder.
[0005] Preferably, the inner wall of the adjusting cylinder is provided with a fixing ring, the outer wall of the fixing ring is provided with an intermediate ring, and the retaining ring is located between the intermediate ring and the inner sleeve. Through the three-layer nested layout design of the fixing ring, the intermediate ring and the retaining ring, multiple functional components can be integrated in a limited radial space.
[0006] Preferably, the outer wall of the fixed ring is provided with multiple sets of outer locking rods, which cooperate with multiple sets of cross-arranged retaining springs. The inner wall of the fixed ring is provided with multiple sets of inner locking rods. The locking cooperation between the outer locking rods and the cross retaining springs achieves reliable fixation of the fixed ring during the locking process, avoiding the problem that the locking spring cannot be tightened due to the fixed ring rotating with the rotating ring.
[0007] Preferably, one end of the fixed ring is connected to multiple sets of locking springs, the other end of the locking spring is connected to a rotating ring, and the other end of the rotating ring is connected to multiple sets of insert rods. The insert rods are inserted into the slots, and the rotational force is reliably transmitted to the rotating ring through the insertion and engagement of the insert rods and the slots.
[0008] Preferably, the inner wall of the fixing ring is provided with an air outlet pipe, and the outer wall of one end of the air outlet pipe is provided with multiple sets of slots that are adapted to the inner locking rod. The inner locking rod is embedded in the slot, and the accurate positioning and anti-rotation function of the air outlet pipe in the fixing ring is realized through the engagement and cooperation between the inner locking rod and the slot.
[0009] Preferably, the other end of the air outlet pipe is connected to a side ring, which abuts against the rotating sleeve. Multiple sets of adjusting plates are rotatably connected inside the side ring. Through the abutting design between the side ring and the rotating sleeve, the entire disassembly and assembly mechanism can be rotated inside the mounting cylinder by rotating the rotating sleeve and the side ring simultaneously while keeping the air outlet pipe locked.
[0010] Preferably, the multiple sets of adjustment plates are connected by an intermediate plate, and the multiple sets of adjustment plates are rotatably connected to the intermediate plate. A lever is provided at the center of the outer side of the intermediate plate. By moving the lever, the intermediate plate can be driven to rotate. The rotatable connection between the intermediate plate and the multiple sets of adjustment plates realizes the synchronous opening and closing of the multiple sets of adjustment plates, thereby realizing the adjustment of the air volume.
[0011] (III) Beneficial Effects Compared with the prior art, this utility model provides an air outlet structure for air conditioning equipment, which has the following beneficial effects: The air outlet structure for air conditioning equipment provided by this utility model, through the design of the disassembly and assembly mechanism, realizes the quick and convenient disassembly and assembly of the air outlet duct and flexible angle adjustment, solving the problem that the air outlet duct is inconvenient to disassemble and clean in the prior art. This structure, through the cooperation of the locking spring and the rotating ring, realizes the tool-based quick locking and release of the air outlet duct. The operator only needs to rotate the rotating sleeve to drive the rotating ring to rotate through the insertion rod. The fixed state of the fixed ring makes the locking spring gradually tighten and tightly wrap around the outer wall of the air outlet duct during the rotation, completing the reliable locking of the air outlet duct. When disassembling, simply rotate the rotating sleeve in the opposite direction to make the locking spring gradually open and release the air outlet duct. The entire installation and disassembly process does not require the use of special tools, and the operation is simple and quick, reducing the difficulty and time cost of cleaning and maintaining the air outlet duct. This allows car owners to regularly disassemble the air outlet duct for cleaning themselves, effectively ensuring the air quality inside the car and the respiratory health of the drivers and passengers.
[0012] Meanwhile, this structure, through the cooperation of the outer clamping rod and multiple sets of cross-arranged retaining springs, achieves stable fixation of the fixing ring during installation, ensuring that the locking spring can be evenly tightened under the drive of the rotating ring without overall rotation. Furthermore, when the locking spring is tightened to the correct position and the rotating sleeve is rotated further, the outer clamping rod will overcome the spring force of the retaining spring and rotate between adjacent retaining springs. This mechanical feedback signal indicates to the operator that the tightening work is complete, avoiding over-tightening or under-tightening, and ensuring the reliability and sealing of the air outlet duct installation. Through the abutment design of the side ring and the rotating sleeve, and the overall rotational capability of the disassembly and assembly mechanism, this structure allows for flexible adjustment of the air outlet angle even when the air outlet duct is locked. Users only need to simultaneously pinch the rotating sleeve and the side ring to rotate them synchronously, which will drive the entire disassembly and assembly mechanism to rotate within the installation cylinder against the spring force of the retaining spring, thereby changing the orientation angle of the air outlet duct to meet the personalized needs of different driving and riding positions for airflow direction, improving the comfort and convenience of the air conditioning system. Additionally, the lever can be used to adjust the middle plate, thereby controlling the opening and closing angles of multiple adjustment plates to adjust the airflow volume.

[0018] Please see Figures 1-5An air outlet structure for an air conditioning device includes a mounting cylinder 11, an inner sleeve 12 on the inner wall of the mounting cylinder 11, and multiple sets of retaining springs 13 arranged crosswise on the inner wall of the mounting cylinder 11, with the retaining springs 13 located on one side of the inner sleeve 12; it also includes a disassembly and assembly mechanism, which includes an adjusting cylinder 21, with the adjusting cylinder 21 rotatably connected to the inner wall of the inner sleeve 12, a rotating sleeve 22 connected to one end of the adjusting cylinder 21, and a retaining ring 23 connected to the other end of the adjusting cylinder 21. The side wall of the retaining ring 23 rotatably abuts against the side wall of the inner sleeve 12. Multiple sets of slots 24 are provided on the inner wall of the adjusting cylinder 21, a fixing ring 25 is provided on the inner wall of the adjusting cylinder 21, an intermediate ring 26 is sleeved on the outer wall of the fixing ring 25, the retaining ring 23 is located between the intermediate ring 26 and the inner sleeve 12, and multiple sets of outer retaining rods 27 are provided on the outer wall of the fixing ring 25, the outer retaining rods 27 cooperating with the multiple sets of crosswise retaining springs 13. In use, the inner wall of the fixed ring 25 is provided with multiple sets of inner locking rods 28. One end of the fixed ring 25 is connected to multiple sets of locking springs 29. The other end of the locking springs 29 is connected to a rotating ring 210. The other end of the rotating ring 210 is connected to multiple sets of insertion rods 211. The insertion rods 211 are inserted into the slots 24. The inner wall of the fixed ring 25 is provided with an air outlet pipe 212. One end of the air outlet pipe 212 has multiple sets of slots 213 adapted to the inner locking rods 28 on its outer wall. The inner locking rods 28 are embedded in the slots 213. The other end of the air outlet pipe 212 is connected to a side ring 214. The side ring 214 abuts against the rotating sleeve 22. Multiple sets of adjusting plates 215 are rotatably connected inside the side ring 214. The multiple sets of adjusting plates 215 are connected to each other through an intermediate plate 216. The multiple sets of adjusting plates 215 are rotatably connected to the intermediate plate 216. A lever 217 is provided at the center of the outer side of the intermediate plate 216.
[0019] In this utility model, the mounting cylinder 11 is fixedly installed to the vehicle body. The locking spring 29 allows for quick locking and disassembly of the air outlet 212, facilitating cleaning. Specifically, when installing the air outlet 212, the operator inserts it between the locking spring 29 and the fixing ring 25, and engages the inner locking rod 28 into the slot 213. Then, the operator can rotate the rotating sleeve 22. Because the insertion rod 211 is inserted into the slot 24, the rotation of the rotating sleeve 22 simultaneously drives the adjusting cylinder 21 and the retaining ring 23 to rotate synchronously, and also drives the rotating ring 210 to rotate synchronously via the insertion rod 211. Figure 2As shown, multiple sets of retaining springs 13 are arranged in two rows, and the two rows of retaining springs 13 are arranged in opposite directions and cross each other. Each set of outer retaining rods 27 is inserted between two adjacent sets of cross retaining springs 13. Therefore, the multiple sets of outer retaining rods 27 arranged on the outside of the fixing ring 25 are locked by the multiple sets of cross retaining springs 13, so the fixing ring 25 is fixed. The rotating ring 210 rotates, but the fixing ring 25 is fixed. Therefore, the locking spring 29 between the rotating ring 210 and the fixing ring 25 will gradually tighten under the rotation of the rotating ring 210 until it tightly wraps around the ring. After the locking spring 29 is tightened to its maximum position and wrapped around the outer wall of the air outlet duct 212, if the rotating sleeve 22 is rotated further, the outer locking rod 27 will overcome the elastic force of the locking spring 13 and rotate to the side between two adjacent sets of locking springs 13, indicating that the locking work is completed. If the air outlet duct 212 needs to be removed, simply rotate the rotating sleeve 22 in the opposite direction, so that the rotating sleeve 22 drives the rotating ring 210 to rotate in the opposite direction through multiple sets of insert rods 211, thereby causing the locking spring 29 to gradually open and release the tight wrapping of the outer wall of the air outlet duct 212.
[0020] The middle plate 216 can be adjusted by moving the lever 217, which in turn adjusts the angle of the multiple sets of adjustment plates 215. When it is necessary to rotate the air outlet pipe 212 to adjust the air outlet angle, the rotating sleeve 22 and the side ring 214 can be pinched at the same time to make them rotate simultaneously. At this time, the overall locking state of the disassembly and assembly mechanism will not be affected. It only drives the multiple sets of outer clamping rods 27 to overcome the elasticity of the clamping spring 13 and rotate inside the mounting cylinder 11, thereby adjusting the air outlet angle.
