Description

Technical Field

[0001] This utility model relates to the technical field of automotive air conditioning parts, specifically the structure of automotive air conditioning vents. Background Technology

[0002] An automotive air conditioner is an air conditioning device installed in a car. Its main functions are to cool, heat, ventilate, and purify the air inside the car to regulate the temperature, humidity, airflow speed, and air quality, providing a comfortable in-car environment for drivers and passengers.

[0003] Existing technology, such as the automotive dashboard air vent structure disclosed in CN203020024U, includes an air vent housing, air vent blades, connecting rods, a dial, and an air vent mounting frame installed within the housing. An air vent rotation center shaft is located at the center of both sides of the air vent housing. An air vent rotation hole, corresponding to the air vent rotation center shaft, is located at the center of both sides of the air vent mounting frame. The air vent mounting frame extends into the air vent rotation hole via the air vent rotation center shaft and is then installed onto the air vent mounting frame. An arc-shaped hole is located on one side of the air vent rotation hole on the air vent mounting frame, with the center of the air vent rotation hole as its center. A limiting post, corresponding to and extending into the arc-shaped hole, is located on the same side of the air vent rotation center shaft on the air vent housing. The distance between the limiting post and the center of the air vent rotation center shaft is equal to the radius of the arc-shaped hole. This invention avoids the problem of 360° rotation of the air vent, improving reliability and safety.

[0004] While existing automotive dashboard air vent structures effectively mitigate risks such as pipe entanglement and structural wear caused by unrestricted 360° rotation of the air vents through the combination of limiting posts and arc-shaped holes, ensuring basic safety and stability, they still have shortcomings in terms of functional practicality and ease of operation. The airflow adjustment dimension is limited, only allowing adjustment of the up-and-down pitch angle of the air vent blades through mechanical transmission, and cannot complete the horizontal left-and-right sweeping action. This results in the airflow coverage being limited to a fixed area, making it difficult to meet the differentiated air supply needs of different positions in the cabin, such as the driver, front passenger, and rear passengers. Especially in multi-passenger scenarios, it is easy to experience localized differences in temperature, posing a safety hazard. Therefore, we propose a new automotive air conditioning vent structure. Utility Model Content

[0005] One of the technical problems that this application aims to solve is that the existing structure can only adjust the air outlet blades up and down but not horizontally, and the lack of convenience and safety due to reliance on manual operation.

[0006] To solve the above-mentioned technical problems, this application provides an automotive air conditioning vent structure, including an vent housing. A driving component is provided inside the vent housing, and multiple evenly distributed upper and lower blades are rotatably connected to the front side of the vent housing. The driving component and the upper and lower blades cooperate with each other to adjust the airflow direction of the air conditioner.

[0007] Preferably, the driving component includes a drive motor disposed on the top of the air outlet box, the output end of the drive motor is fixedly connected to a worm gear, the worm gear is vertically installed on the front side of the air outlet box, and a plurality of evenly distributed worm wheels are horizontally installed inside the front side of the air outlet box. The worm wheels mesh with the worm gear, the end of the worm wheel away from the worm gear is fixedly connected to the upper and lower blades, and the end of the upper and lower blades away from the worm wheel is rotatably connected to the inner wall of the air outlet box.

[0008] Preferably, the bottom of the air outlet box is rotatably connected to multiple evenly distributed horizontal blades, one of which is slidably fitted with an adjusting slider on its outer periphery. Multiple evenly distributed fixing blocks are provided on the side of the adjusting slider near the inner wall of the air outlet box. A limiting groove is opened on the side of the horizontal blade near the upper and lower blades. A fixing rod is vertically installed inside the limiting groove. The fixing rod is slidably connected to a slot opened in the middle of the fixing block.

[0009] Preferably, both sides of the air outlet box are provided with air inlets for gas to enter.

[0010] Preferably, two filter plates are slidably connected inside both sides of the air outlet box. A telescopic rod is vertically installed inside the front side of the filter plate. A return spring is sleeved on the outer periphery of the side with the smaller radius of the telescopic rod. The top of the telescopic rod slides through the top of the filter plate. A limit protrusion is fixedly connected to the top of the filter plate. A lever is fixedly connected to the outer wall of the side with the larger radius of the telescopic rod.

[0011] Preferably, the middle part of the filter plate uses an activated carbon filter screen.

[0012] Preferably, a handle is provided on the front side of the filter plate.

[0013] This utility model has at least the following beneficial effects: 1. By cooperating with the drive components and the upper and lower blades, and combining the linkage design of the horizontal blades, the limitation of traditional structures that can only be adjusted in one direction is broken. The drive motor drives the worm gear and worm wheel transmission, which can precisely control the upper and lower blades to achieve pitch angle adjustment. At the same time, when the upper and lower blades move, the horizontal blades are driven to complete the horizontal left and right sweeping through the sliding cooperation of the adjustment block and the fixed rod, forming a three-dimensional air supply range. This can meet the differentiated air supply needs of different areas in the cabin, such as the driver, passenger, and rear seats, and solve the problem of different body sensations in multi-person driving scenarios.

[0014] 2. The self-locking characteristic of worm gear transmission not only maintains the stability of the blade angle, but also prevents sudden changes in wind direction caused by accidental contact. Even if the blade is subjected to external force, it will not drive the worm gear and worm in the opposite direction, ensuring that the set air delivery angle is not disturbed. Especially during operation, it can avoid local overcooling or overheating caused by accidental contact, thus enhancing the safety of use. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1 Please see Figures 1-6 This utility model provides a technical solution: The car air conditioning vent structure includes an vent box 1, inside which a drive component 8 is provided. Multiple evenly distributed upper and lower blades 4 are rotatably connected to the front side of the vent box 1. The drive component 8 and the upper and lower blades 4 cooperate with each other to adjust the airflow direction of the air conditioning.

[0019] Furthermore, the driving component 8 includes a driving motor 2 disposed on the top of the air outlet box 1. The output end of the driving motor 2 is fixedly connected to a worm gear 7. The worm gear 7 is vertically installed on one side of the front of the air outlet box 1. Multiple evenly distributed worm wheels 9 are horizontally installed inside the front side of the air outlet box 1. The worm wheels 9 mesh with the worm gear 7. The end of the worm wheel 9 away from the worm gear 7 is fixedly connected to the upper and lower blades 4. The end of the upper and lower blades 4 away from the worm wheel 9 is rotatably connected to the inner wall of the air outlet box 1.

[0020] Furthermore, the bottom of the air outlet box 1 is rotatably connected to multiple evenly distributed horizontal blades 11. One of the upper and lower blades 4 is slidably fitted with an adjusting slider 5 on its outer periphery. The adjusting slider 5 is provided with multiple evenly distributed fixing blocks 14 on the side near the inner wall of the air outlet box 1. The horizontal blade 11 is provided with a limiting groove 15 on the side near the upper and lower blades 4. A fixing rod 13 is vertically installed inside the limiting groove 15. The fixing rod 13 is slidably connected to the slot provided in the middle of the fixing block 14.

[0021] Furthermore, air inlets 6 are provided on both sides of the air outlet box 1 to allow gas to enter.

[0022] In use, when it is necessary to adjust the longitudinal air outlet angle, the drive motor 2 at the top of the air outlet box 1 is started. The output end of the drive motor 2 drives the worm gear 7 to rotate vertically. Since the worm gear 7 meshes with multiple worm wheels 9 distributed laterally inside the front side of the air outlet box 1, the worm wheels 9 rotate with the worm gear 7 and synchronously drive the upper and lower blades 4 fixedly connected to it to rotate (the end of the upper and lower blades 4 away from the worm wheel 9 is rotatably connected to the inner wall of the air outlet box 1 to form a stable support). By changing the pitch angle of the upper and lower blades 4, the longitudinal air direction can be adjusted. When the upper and lower blades 4 rotate, the adjusting block 5 sleeved on the outer periphery of one of the upper and lower blades 4 can be moved synchronously with it. The adjusting block 5 leans against The adjusting block 14 on one side of the inner wall of the near air outlet box 1 slides with the fixing rod 13 in the limiting groove 15 of the horizontal blade 11 through the central slot, pushing the horizontal blade 11 to rotate around its own axis. Multiple horizontal blades 11 move synchronously through the linkage structure to achieve horizontal left and right sweeping, which, together with the upper and lower blades 4, forms a three-dimensional air supply range. The meshing structure of the worm gear 9 and worm 7 in the drive component 8 has a self-locking characteristic (only the worm 7 can drive the worm gear 9 to rotate, and the worm gear 9 cannot drive the worm 7 in the opposite direction). Therefore, after the upper and lower blades 4 and the horizontal blades 11 are adjusted to the correct position, they can still maintain a stable angle even if they are subjected to airflow impact or vehicle vibration, thus avoiding wind direction deviation.

[0023] Example 2 Please see Figures 4-7 This utility model provides a technical solution: two filter plates 3 are slidably connected inside both sides of the air outlet box 1. A telescopic rod 16 is vertically installed inside the front side of the filter plate 3. A return spring 17 is sleeved on the outer periphery of the side with the smaller radius of the telescopic rod 16. The top of the telescopic rod 16 slides through the top of the filter plate 3. A limiting protrusion 12 is fixedly connected to the top of the filter plate 3. A toggle block 18 is fixedly connected to the outer wall of the side with the larger radius of the telescopic rod 16.

[0024] Furthermore, the middle part of the filter plate 3 uses an activated carbon filter screen.

[0025] Furthermore, a handle 10 is provided on the front side of the filter plate 3.

[0026] Unlike Embodiment 1, outside air enters through the air inlets 6 on both sides of the air outlet box 1 and first flows through the filter plates 3 inside the air outlet box 1. The activated carbon filter in the middle of the filter plate 3 adsorbs and purifies the dust, odors, and harmful gases in the air. The purified air is guided by the upper and lower blades 4 and the horizontal blades 11 and sent into the vehicle from the air outlet end of the air outlet box 1. When it is necessary to remove the filter plate 3, the lever 18 on the front side of the filter plate 3 is moved, which drives the telescopic rod 16 to compress the return spring 17, so that the top of the telescopic rod 16 retracts into the filter plate 3 and disengages from the limiting structure of the air outlet box 1; the filter plate 3 can be pulled out from the air outlet box 1 by holding the handle 10. During installation, push the filter plate 3 along the guide rail. After positioning by the limiting protrusion 12, release the lever 18. The return spring 17 pushes the telescopic rod 16 back to its original position, and its top engages with the limiting hole of the air outlet box 1, thus fixing the filter plate 3. The filter plate 3 uses an activated carbon filter, which can effectively intercept dust, particulate matter and other impurities in the air, preventing them from entering the air outlet box 1 and accumulating on the rotating shaft of the upper and lower blades 4 and the horizontal blades 11 or at the sliding contact between the adjusting block 14 and the fixing rod 13. This reduces problems such as blade adjustment jamming and increased resistance caused by impurities, ensuring that the pitch adjustment of the upper and lower blades 4 and the left and right sweeping action of the horizontal blades 11 are always smooth and maintaining long-term stable adjustment accuracy. The airflow after being purified by the filter plate 3 is more uniform, reducing the airflow turbulence caused by impurities in unfiltered air. The stable airflow makes the direction and volume guidance control of the upper and lower blades 4 and the horizontal blades 11 more precise when adjusting the angle, avoiding local airflow deviation caused by impurities, making the adjustment effect of different angles more in line with expectations, and improving the practical value of multi-dimensional adjustment.
