Description

Technical Field

[0001] This utility model relates to the field of automotive component technology, specifically to a modular air duct for automotive air conditioning. Background Technology

[0002] The modular air duct for automotive air conditioning is a core modular component responsible for airflow transmission and distribution in an automotive air conditioning system. Through a standardized modular structure design, this air duct can flexibly adapt to the air conditioning system layout of different vehicle models (such as passenger cars and commercial vehicles), precisely delivering the cold or hot air generated by the air conditioning unit to different areas inside the vehicle, such as the driver's seat, front passenger seat, and rear seats. Simultaneously, its sealed structure reduces airflow leakage, ensuring uniform temperature regulation throughout the vehicle and improving the comfort of passengers. Its modular nature also facilitates the assembly, production, and after-sales maintenance of the air conditioning system—faulty modules can be replaced individually without disassembling the entire air conditioning system. This makes it suitable for both automotive manufacturing and after-sales maintenance scenarios, ensuring efficient operation and low-cost maintenance of automotive air conditioning systems.

[0003] Traditional modular air ducts for automotive air conditioning systems suffer from significant shortcomings in terms of the ease of quick disassembly and the stability of their snap-fit ​​mechanisms. Most air ducts require specialized tools such as screwdrivers and wrenches to insert and remove pins, making the process cumbersome, especially in confined spaces like the car's center console where tool use is limited, resulting in extremely low efficiency for replacing or repairing air duct modules. While some air ducts simplify the snap-fit ​​operation, they lack return springs and misalignment locking designs, making the pins prone to loosening due to vibrations during vehicle operation. This not only causes airflow leakage (affecting air conditioning cooling / heating performance) but may also produce abnormal noises due to component collisions. Furthermore, existing snap-fit ​​mechanisms often lack anti-slip mechanisms on their operating parts, making them prone to slippage when hands are wet or operating space is limited, hindering precise control of operating force. The lack of reliable limiting structures also allows moving parts to easily shift due to external forces, causing pins to accidentally detach, further exacerbating the connection instability problem and failing to meet the core requirements of automotive air conditioning systems for "quick disassembly and long-term stability." Therefore, we propose a modular air duct for automotive air conditioning systems. Utility Model Content

[0004] One of the technical problems this application aims to solve is that existing automotive component air ducts have cumbersome disassembly and assembly processes and lack reliable limiting structures, which cannot meet the core requirements of automotive air conditioning systems for quick disassembly and assembly and long-term stability.

[0005] To address the aforementioned technical problems, this application provides a modular air duct for automotive air conditioning, including a snap-fit ​​mechanism. The snap-fit ​​mechanism includes a limiting mechanism, and a movable mechanism is movably connected to one side of the inner wall of the limiting mechanism. The movable mechanism includes a movable block, and a return spring is connected to one side of the outer wall of the movable block. A connecting rod is fixedly connected to the side of the movable block away from the return spring. A limiting component is fixedly connected to the side of the connecting rod away from the movable block. A pushing block is fixedly connected to the side of the limiting component away from the connecting rod. Multiple anti-slip blocks are fixedly connected to one side of the outer wall of the pushing block, and a locking block is fixedly connected to one side of the outer wall of the pushing block.

[0006] In some embodiments, a first housing is fixedly connected to the lower outer wall of the snap-fit ​​mechanism, a second housing is movably connected to one side of the outer wall of the first housing, and a pin is fixedly connected to one side of the upper outer wall of the second housing, with one side of the pin corresponding to one side of the snap-fit ​​mechanism.

[0007] In some embodiments, the limiting mechanism includes a housing, a communicating groove is provided on one side of the middle portion of the housing, two sliding grooves are provided on each of the outer walls of the housing, a groove is provided on each of the outer walls of the housing, and a limiting rod is fixedly connected to each of the outer walls of the housing.

[0008] In some embodiments, the anti-slip block and the locking block are located on the same side of the pushing block, and the locking block is engaged with one side of the limiting rod.

[0009] In some embodiments, a limiting member provided on one side of the push block is movably connected to a groove opened on the side wall of the housing.

[0010] In some embodiments, one side of the push block is connected to a groove formed on the outer wall of one side of the housing.

[0011] In some embodiments, the movable block is movably connected to one side of the inner wall of the housing, and the middle part of the movable block is correspondingly connected to the connecting groove.

[0012] In some embodiments, the movable block is movably connected to one side of the inner wall of the housing, and the middle part of the movable block is correspondingly connected to the connecting groove.

[0013] This utility model has at least the following beneficial effects: In use, the core structure of this invention, consisting of a limiting mechanism (outer shell, slide groove, groove, limiting rod), a movable mechanism (moving block, return spring, connecting rod, limiting component, pushing block), and a pin, plays a key role in ensuring the quick and easy disassembly and stable connection of the snap-fit ​​mechanism. No tools are required for operation. Simply push the push block with anti-slip slider (which provides damping to prevent slippage) to slide it along the groove of the outer shell. When the push block reaches the groove position, press it down (the push block is malleable and bendable). The locking block on one side engages with the limiting rod, which in turn drives the movable block to squeeze the return spring through the connecting rod, making the middle of the movable block completely aligned with the connecting groove of the outer shell. At this point, the pin can be easily inserted and removed. After disassembly, press the locking block and slide the push block in the opposite direction. The return spring will drive the movable block to return to its original position through the reaction force, causing the movable block to misalign with the connecting groove. The misalignment difference firmly locks the pin. At the same time, the locking block and the limiting rod continuously limit the movement, preventing the pin from falling off due to the movable block shifting due to external force. This achieves a very simple operation process of pushing, pressing, and inserting / removing, while ensuring the stability of the connection and avoiding the risk of loosening. In use, this utility model ensures high efficiency in housing connection and ease of maintenance through a cooperative structure consisting of a first housing, a second housing, and multiple sets of snap-fit ​​mechanisms and pins. The outer wall of the first housing has multiple snap-fit ​​mechanisms, and the outer wall of the second housing has correspondingly multiple pins. Through the one-to-one connection of the multiple sets of snap-fit ​​mechanisms and pins, the overall assembly or disassembly of the first and second housings can be completed quickly, eliminating the need for tedious point-by-point operations. This multi-set cooperative design not only improves the overall stability of the housing connection but, more importantly, significantly simplifies the subsequent maintenance process. When maintenance of internal components is required, the housing can be quickly disassembled, and after repair, it can be efficiently reassembled, significantly reducing maintenance time and improving work efficiency. It is suitable for various housing equipment scenarios requiring frequent assembly and disassembly for maintenance. Attached Figure Description

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.

[0017] Example 1: Please refer to Figure 1-4 This utility model provides a technical solution: a modular air duct for automotive air conditioning, including a snap-fit ​​mechanism 1, which includes a limiting mechanism 11. The limiting mechanism 11 includes a housing 111, a connecting groove 112 on one side of the middle of the housing 111, two sliding grooves 113 on each side of the outer wall of the housing 111, and a recess 114 on each side of the outer wall of the housing 111. A limiting rod 115 is fixedly connected to each side of the outer wall of the housing 111. A movable mechanism 12 is movably connected to one side of the inner wall of the limiting mechanism 11. The movable mechanism 12 includes a movable block 121, which is movably connected to one side of the inner wall of the housing 111, and the middle of the movable block 121 is correspondingly connected to the connecting groove 112. Correspondingly, a return spring 122 is connected to one side of the outer wall of the movable block 121. A connecting rod 123 is fixedly connected to the side of the movable block 121 away from the return spring 122. A limiting member 124 is fixedly connected to the side of the connecting rod 123 away from the movable block 121. A pushing block 125 is fixedly connected to the side of the limiting member 124 away from the connecting rod 123. The limiting member 124 on one side of the pushing block 125 is movably connected to the slide groove 113 opened on the side wall of the outer shell 111. One side of the pushing block 125 is correspondingly connected to the groove 114 opened on one side of the outer wall of the outer shell 111. Multiple anti-slip blocks 126 are fixedly connected to one side of the outer wall of the pushing block 125. A locking block 127 is fixedly connected to one side of the outer wall of the pushing block 125. The anti-slip blocks 126 and the locking block 127 are located on the same side of the pushing block 125, and the locking block 127 is engaged with one side of the limiting rod 115.

[0018] In this embodiment, a locking mechanism 1 is designed, which includes a limiting mechanism 11 and a movable mechanism 12. The limiting mechanism 11 includes a housing 111, with a connecting groove 112 formed on one side of the middle portion of the housing 111, penetrating the housing 111. Two sliding grooves 113 are formed on both outer walls of the housing 111. A recess 114 is formed at one end of the sliding groove 113 and on both outer walls of the housing 111, the recess 114 being inwardly recessed. A limiting rod 115 is fixedly connected to one outer wall of the recess 114 and to both outer walls of the housing 111. The movable mechanism 12 includes a movable block 121, with a return spring 122 fixedly connected to one outer wall of the movable block 121. 122 is connected to one side of the inner wall of the outer shell 111, and the other side of the movable block 121 is fixedly connected to the limiting member 124 via the connecting rod 123. The limiting member 124 can be slidably connected to one side of the inner wall of the slide groove 113, and extends to one side of the outer wall of the outer shell 111 and is fixedly connected to the pushing block 125. Therefore, the pushing block 125 is located on one side of the outer wall of the slide groove 113, and the pushing block 125 has a certain degree of plasticity, that is, one end can be pressed and bent. A locking block 127 is fixedly connected to the outer wall of the bent side of the pushing block 125, and multiple anti-slip blocks 126 are provided on one side of the outer wall of the pushing block 125. The anti-slip blocks 126 can play a damping role, making it easy to push the pushing block 125 without slipping. A pin 4 is provided. 4 can penetrate the connecting groove 112 opened in the middle of the movable block 121 and the middle of the outer shell 111, and a groove is opened on one side of the pin 4, which can be engaged with one side of the inner wall of the middle of the movable block 121. Therefore, when the pin 4 is engaged with the inner wall of the middle of the movable block 121, the first shell 2 and the second shell 3 can be connected. When the push block 125 slides along the slide groove 113 to one side and reaches the groove 114, it is pressed. At this time, the locking block 127 provided on one side of the push block 125 is connected with the limiting rod 115 and moves to the other side of the limiting rod 115. At this time, the push block 125 will drive the movable block 121 to shift through the connecting rod 123. At this time, it will squeeze the return spring 122 on the other side, so that the middle of the movable block 121 engages with the connecting groove. When 112 is fully aligned, the pin 4 can be removed from the connecting groove 112 and the movable block 121. Conversely, when the locking block 127 is pressed and the pushing block 125 is slid outward, the return spring 122 will reset the movable block 121 through the reaction force. At this time, the movable block 121 and the connecting groove 112 are misaligned. The misalignment difference can lock the pin 4 in place. At this time, the locking block 127 is located on the other side of the limiting rod 115. Through the action of the locking block 127 and the limiting rod 115, the movable block 121 will not be displaced due to external force, thus preventing the pin 4 from falling off. Therefore, this method allows for quick disassembly without the need for tools, which is convenient for installation and ensures the stability of the installation.

[0019] Example 2: Please refer to Figure 1-3 The lower outer wall of the snap-fit ​​mechanism 1 is fixedly connected to the first housing 2, and the outer wall of one side of the first housing 2 is movably connected to the second housing 3. The upper outer wall of the second housing 3 is fixedly connected to the pin 4, and one side of the pin 4 is correspondingly connected to one side of the snap-fit ​​mechanism 1.

[0020] In this embodiment, a first housing 2 is fixedly connected to the lower end of the snap-fit ​​mechanism 1, and a plurality of snap-fit ​​mechanisms 1 are provided on one side of the outer wall of the first housing 2. A second housing 3 is movably connected to the other side of the first housing 2, and a plurality of pins 4 are provided on one side of the outer wall of the second housing 3. The pins 4 can be connected to the snap-fit ​​mechanisms 1 provided on one side of the outer wall of the first housing 2. Therefore, by connecting the plurality of snap-fit ​​mechanisms 1 and the pins 4, the first housing 2 and the second housing 3 can be quickly installed and disassembled, which facilitates subsequent maintenance operations and improves work efficiency.
