Description
Technical Field
[0001] This utility model relates to the field of grille cover technology, and in particular to a detachable grille cover for automotive air conditioning vents. Background Technology
[0002] Traditional automotive air conditioning vent grille covers are typically fixed using screw connections. This involves setting multiple mounting holes along the edge of the grille cover and using screws to directly fix it into the corresponding threaded holes inside the air conditioning vent cavity. This fixing method is widely used in the automotive manufacturing industry. Its core principle is to achieve a rigid connection between the grille cover and the air vent body through the interlocking force of mechanical fasteners, ensuring that the grille cover will not fall off due to air conditioning wind or vibration during use.
[0003] When using grille covers, the traditional fixing methods described above have significant efficiency drawbacks in practical applications. Specifically, when cleaning or replacing the grille cover (such as cleaning accumulated dust, replacing damaged parts, or adapting to different interior styles), users need to use tools such as screwdrivers to tighten multiple screws one by one. The operation is cumbersome and time-consuming. Furthermore, the screws are prone to unstable fixing due to thread wear during repeated disassembly and assembly, and may even be lost due to improper operation. In addition, the rigid connection method of screw fixing requires high installation accuracy. If there is a slight deviation between the mounting holes of the grille cover and the inner cavity of the air outlet, the screws may not be able to be screwed in smoothly or the grille cover may be subjected to uneven force, thereby affecting the air outlet stability of the air conditioner.
[0004] Therefore, to address the issue of inconvenience in improving disassembly and assembly efficiency during maintenance, a detachable grille cover for automotive air conditioning vents can be designed. When installing this grille cover, first align it with the inner cavity of the air conditioning vent and press it in. At this point, the annular groove on the outer circumference of the detachable grille cover is aligned with the arc-shaped blocks on the upper and lower sides of the inner cavity of the air conditioning vent on the same vertical plane. Then, a locking operation is performed: the convex component slides inward, at which point the adjusting mechanism disengages from the convex component, releasing elastic potential energy and pushing the arc-shaped blocks downward until... The arc-shaped block is fully embedded in the annular groove on the outer circumference of the detachable grille cover, forming a vertical limiting engagement. When the convex part is released, it slides back to its original position. The bottom wall of the convex part covers the top of the adjustment mechanism and forms a vertical limiting on the arc-shaped block, thus stably locking the arc-shaped block in the annular groove. The operation is repeated on another set of arc-shaped blocks to complete the installation of the detachable grille cover. When disassembling, the operation needs to be reversed. In summary, through the optimized design of the mechanical structure, this device significantly improves the installation and disassembly efficiency and maintenance convenience of automotive air conditioning vent grille covers while ensuring functional reliability.

At this time, the annular groove on the outer circumference of the removable grille cover is exactly on the same vertical plane as the arc-shaped blocks on the upper and lower sides of the inner cavity of the air conditioner vent. Then, perform the locking operation: drive the shaped part to slide inward. At this time, the adjusting mechanism is released from the restraint of the shaped part and releases elastic potential energy, pushing the arc-shaped block downward until the arc-shaped block is completely embedded in the annular groove on the outer circumference of the removable grille cover, forming... The upper and lower limit engagement allows the convex part to be released for reset sliding. The bottom wall of the convex part covers the top of the adjustment mechanism and forms a vertical limit on the arc-shaped block, thus stably locking the arc-shaped block in the annular groove. The operation is repeated on another set of arc-shaped blocks to complete the installation of the detachable grille cover. When disassembling, the operation needs to be reversed. In summary, through the optimized design of the mechanical structure, this device significantly improves the installation and disassembly efficiency and maintenance convenience of the automotive air conditioning vent grille cover while ensuring functional reliability.
[0008] Preferably, the inner wall of the air conditioner outlet cavity is fixedly provided with multiple sets of plug-in cylinders, and the inner wall of the detachable grille cover is fixedly provided with multiple sets of plug-in posts.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0025] Please see Figure 1 and Figure 3 This utility model provides an embodiment: a detachable grille cover for an automotive air conditioning vent, including a detachable grille cover 1, which is embedded in the inner cavity of the air conditioning vent, and the inner diameter of the inner cavity of the air conditioning vent is adapted to match the outer diameter of the outer wall of the detachable grille cover 1. An annular groove 2 is provided on the outer peripheral surface of the detachable grille cover 1. It also includes two sets of arc-shaped blocks 3. Arc-shaped blocks 3 are provided on the upper and lower inner walls of the inner cavity of the air conditioning vent. The two sets of arc-shaped blocks 3 are respectively engaged in the upper and lower inner cavities of the annular groove 2. Each set of arc-shaped blocks 3 is provided with an adjustment mechanism and a U-shaped part 4. The U-shaped part 4 is used to lock and limit the arc-shaped block 3.
[0026] Please see Figure 2 and Figure 3Multiple sets of plug-in cylinders 5 are fixedly installed on the inner wall of the air conditioner vent cavity, and multiple sets of plug-in posts 6 are fixedly installed on the inner wall of the detachable grille cover 1. The multiple sets of plug-in posts 6 are adapted and engaged with the multiple sets of plug-in cylinders 5 respectively, and the multiple sets of plug-in posts 6 and the multiple sets of plug-in cylinders 5 are arranged in a circumferential array. First, the plug-in posts 6 on the outer wall of the detachable grille cover 1 are aligned with the plug-in cylinders 5 in the inner cavity of the air conditioner vent cavity and pressed in. The initial positioning of the detachable grille cover 1 is achieved by utilizing the circumferential array distribution design of the plug-in posts 6 and plug-in cylinders 5.
[0027] Please see Figure 4 and Figure 6 The adjustment mechanism includes an L-shaped rod 7 and a return spring 8. Receiving cavities are provided on the upper and lower inner walls of the air conditioner outlet cavity. An L-shaped rod 7 is slidably mounted on the inner wall of the receiving cavity. A return spring 8 is fixedly connected between the top of the arc-shaped block 3 and the inner wall of the receiving cavity. The horizontal end of the L-shaped rod 7 is engaged in the inner cavity of the U-shaped part 4. The return spring 8 is in a contracted state, and the arc-shaped block 3 is completely retracted into the receiving cavity to avoid obstructing the subsequent installation path. The lower end of the vertical rod of the L-shaped rod 7 is fixedly connected to the top of the arc-shaped block 3. The outer end of the horizontal rod of the L-shaped rod 7 extends to the outside of the air conditioner outlet. The upper end of the return spring 8 is fixedly connected to the inner wall of the receiving cavity, and the lower end of the return spring 8 is fixedly connected to the top of the arc-shaped block 3. The return spring 8 releases its elastic potential energy when it is no longer pressed by the U-shaped part 4, pushing the arc-shaped block 3 downwards from the receiving cavity until the arc-shaped block 3 is completely embedded in the annular groove 2 on the outer circumference of the detachable grille cover 1, forming a vertical limiting engagement.
[0028] Please see Figure 5 and Figure 6 The upper and lower inner walls of the air conditioner outlet cavity are provided with adjustment chambers. A guide rod 9 is fixedly installed inside the adjustment chamber. The shaped part 4 is slidably sleeved on the outer wall of the guide rod 9. The shaped part 4 slides smoothly along the guide rod 9. An adjustment rod 10 is fixedly installed on the outer wall of the shaped part 4. A limit ring 11 is fixedly installed at the end of the guide rod 9. An adjustment spring 12 is fixedly connected between the inner wall of the shaped part 4 and the inner wall of the adjustment cavity. Pulling the adjustment rod 10 outward, the shaped part 4 slides smoothly along the guide rod 9. One end of the adjustment spring 12 is fixedly connected to the inner wall of the adjustment cavity, and the other end is fixedly connected to the inner wall of the shaped part 4. The outer end of the adjustment rod 10 extends to the outside of the air conditioner outlet. When the adjustment spring 12 returns to its original shape, it pushes the shaped part 4 to slide along the guide rod 9.
[0029] When using this grille cover, the core working principle of this detachable grille cover for automotive air conditioning vents is to achieve quick disassembly and assembly through the collaboration of multiple components. The specific operation process is as follows.
[0030] When in the uninstalled state, the two groups of arc-shaped blocks 3 are respectively stored in the storage cavities on the upper and lower sides of the inner cavity of the air conditioner air outlet. At this time, the end of the crossbar of the L-shaped rod 7 is engaged in the inner cavity of the C-shaped member 4, and the return spring 8 is in a contracted state. The arc-shaped block 3 is completely retracted into the storage cavity to avoid blocking the subsequent installation path.
[0031] When the detachable grille cover 1 needs to be installed, first align the insertion posts 6 on the outer wall of the detachable grille cover 1 with the insertion cylinders 5 in the inner cavity of the air conditioner air outlet and press them in. Using the circumferential array distribution design of the insertion posts 6 and the insertion cylinders 5, the preliminary positioning of the detachable grille cover 1 is achieved, ensuring that its axis coincides with the axis of the inner cavity of the air conditioner air outlet.
[0032] At this time, the annular groove 2 on the outer peripheral surface of the detachable grille cover 1 is exactly in the same vertical plane as the arc-shaped blocks 3 on the upper and lower sides of the inner cavity of the air conditioner air outlet. Then, the locking operation is carried out: pull the adjustment rod 10 outside the air conditioner air outlet by hand (the upper and lower groups can be operated step by step). The adjustment rod 10 drives the C-shaped member 4 to slide into the adjustment cavity along the guide rod 9. The inner wall of the C-shaped member 4 squeezes the adjustment spring 12 to cause it to deform (compress). At this time, the end of the crossbar of the L-shaped rod 7 originally limited by the inner cavity of the C-shaped member 4 breaks free from the restraint of the C-shaped member 4. The return spring 8 releases its elastic potential energy due to the loss of the suppression of the C-shaped member 4 and pushes the arc-shaped block 3 to extend downward (the upper arc-shaped block 3) from the storage cavity until the arc-shaped block 3 is completely embedded in the annular groove 2 on the outer peripheral surface of the detachable grille cover 1, forming a vertical limit engagement in the up and down direction. At this time, release the adjustment rod 10, and the adjustment spring 12 restores its deformation and pushes the C-shaped member 4 to slide in the reverse direction along the guide rod 9. The bottom wall of the C-shaped member 4 covers the top of the crossbar of the L-shaped rod 7, forming a vertical limit on the crossbar of the L-shaped rod 7 through the "C" - shaped structure of the C-shaped member 4 to prevent the L-shaped rod 7 from retracting due to the elastic force of the return spring 8, thereby stably locking the arc-shaped block 3 in the annular groove 2 and completing the installation of the detachable grille cover 1.
[0033] When disassembling, the reverse operation is required: pull the adjustment rod 10 outside again. The C-shaped member 4 slides along the guide rod 9 and disengages from the top of the crossbar of the L-shaped rod 7, releasing the limit on the L-shaped rod 7. At this time, pulling the L-shaped rod 7 by hand can drive the arc-shaped block 3 to disengage from the annular groove 2 and retract into the storage cavity. Then release the adjustment rod 10, and the adjustment spring 12 restores its deformation and pushes the C-shaped member 4 to slide along the guide rod 9. The end of the crossbar of the L-shaped rod 7 is engaged in the inner cavity of the C-shaped member 4 and returns to the initial state. Then pull the detachable grille cover 1 outside to separate the insertion posts 6 from the insertion cylinders 5, and the detachable grille cover 1 can be taken out from the inner cavity of the air conditioner air outlet.
[0034] In summary, this detachable grille cover achieves the following core advantages through the circumferential array positioning of the plug-in post 6 and the plug-in cylinder 5, the engagement and limiting of the arc-shaped block 3 and the annular groove 2, and the linkage locking design of the L-shaped rod 7 and the chamfered part 4: First, installation or removal can be completed simply by pulling the adjusting rod 10, without the need for tools, simplifying the operation and significantly shortening maintenance time. Second, the engagement of the arc-shaped block 3 and the annular groove 2 forms multi-directional limiting, which, combined with the positioning of the plug-in post 6 and the plug-in cylinder 5, effectively prevents the grille cover from loosening or falling off, ensuring the stability of the air conditioning vents. Third, all components are integrated between the air conditioning vent cavity and the detachable grille cover 1, requiring no additional space and meeting the compact design requirements of automotive interiors. Fourth, the detachable grille cover 1 is independently designed and can be replaced separately when damaged, reducing overall maintenance costs and improving user experience. In conclusion, through the optimized design of the mechanical structure, this device significantly improves the installation and removal efficiency and maintenance convenience of automotive air conditioning vent grille covers while ensuring functional reliability.
[0035] Through the above steps, when using this grille cover, if it is necessary to install the removable grille cover 1, first align the removable grille cover 1 with the inner cavity of the air conditioner vent and press it in. At this time, the annular groove 2 on the outer circumference of the removable grille cover 1 is exactly on the same vertical plane as the arc-shaped blocks 3 on the upper and lower sides of the inner cavity of the air conditioner vent. Then, perform the locking operation: drive the convex part 4 to slide inward. At this time, the adjusting mechanism is released from the restraint of the convex part 4 and releases elastic potential energy, pushing the arc-shaped block 3 downward until the arc-shaped block 3 is completely embedded in the annular groove 2 on the outer circumference of the removable grille cover 1. This forms a vertical limiting engagement. When the convex part 4 is released, it resets and slides. The bottom wall of the convex part 4 covers the top of the adjustment mechanism and forms a vertical limiting on the arc block 3, thereby stably locking the arc block 3 in the annular groove 2. The operation is repeated on another set of arc blocks 3 to complete the installation of the detachable grille cover 1. When disassembling, the operation needs to be reversed. In summary, through the optimized design of the mechanical structure, this device significantly improves the disassembly and assembly efficiency and maintenance convenience of the automotive air conditioning vent grille cover while ensuring functional reliability.
[0036] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
