Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, specifically to an air conditioning outlet device with a self-locking air guide plate to prevent it from falling off. Background Technology

[0002] In utility model patent application CN218906853U, published on April 25, 2023, entitled "A Front Blade Anti-Drop-Off Device," this utility model discloses a front blade anti-drop-off device, including a mounting base. The mounting base has an air outlet adjustment mechanism on its front side, used to adjust the angle of the air conditioning outlet. The air outlet adjustment mechanism consists of multiple sets of blades, divided into upper and lower blades. Connecting posts are fixed at both ends of the upper and lower blades, and a snap-fit ​​connector is fixed on one side of each connecting post. This utility model, through the design of the snap-fit ​​mechanism, uses the interplay of the snap-fit ​​connector, protrusion, and slot to better connect the air outlet adjustment mechanism with the left and right mounting plates. After the snap-fit ​​connector enters the slot, the protrusion abuts against the side wall of the slot. Simultaneously, through the design of the sliding groove and slider, when the vehicle experiences bumps during driving, the multiple sets of blades can be tightly connected to the left and right mounting plates, preventing blade displacement due to vehicle vibrations.

[0003] In the prior art, including the aforementioned patents, the air deflector of the air vent in existing air conditioning equipment is prone to loosening or even falling off during long-term use due to frequent opening and closing adjustments and the impact of wind. This not only affects the normal operation of the air conditioner but may also cause the deflector to fall and be damaged, posing a certain safety hazard. Furthermore, existing deflector adjustment methods are relatively simple, mostly relying on manual adjustment, which lacks precision and convenience, making it difficult to meet the diverse needs of users. Therefore, there is a need to design an air vent device with a self-locking air guide plate to prevent it from falling off. Utility Model Content

[0004] The purpose of this invention is to provide an anti-fall-off air conditioning outlet device with a self-locking air guide plate, so as to solve the problem of the air baffle loosening when closed as mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-fall-off air conditioner outlet device with a self-locking air guide plate, comprising an air conditioner body, a frame snapped onto the front of the air conditioner body, an air outlet channel installed inside the air conditioner body, a front cover snapped onto the front of the frame, a baffle plate pivotally connected to the inner wall of the frame, a support frame installed inside the air conditioner body, an anti-fall-off adjustment component installed inside the support frame, and a self-locking component installed on the other side of the support frame.

[0006] Furthermore, the internal components of the anti-fall adjustment assembly include a drive motor, a lead screw, a guide rod, a sliding table, a balance bar, a buffer spring, a linkage rod, and a connecting sleeve. The drive motor is mounted on the outer wall of the support frame, and the output shaft of the drive motor is fixedly connected to the lead screw via a coupling. The sliding table is threaded onto the outer wall of the lead screw, and a guide rod is threaded through one side of the sliding table. The balance bar is fixedly connected to the inner wall of the support frame, and a buffer spring is threaded through the balance bar. The bottom pivot of the sliding table is connected to a linkage rod, and a connecting sleeve is fixedly connected to one end of the linkage rod.

[0007] Furthermore, the guide rod and the lead screw are parallel to each other, and the balance bar passes through the sliding table. The sliding table is connected to the wind deflector shaft via a linkage rod and a connecting sleeve.

[0008] Furthermore, the self-locking assembly includes a connecting block, a return spring, a self-locking rod, and a traction rope. One end of the support frame is fixedly connected to the connecting block, the connecting block is equipped with a return spring, the return spring is fixedly connected to the self-locking rod, and one end of the self-locking rod is fixedly connected to the traction rope.

[0009] Furthermore, the self-locking rod is fixed in the internal channel of the connecting block by a reset spring, and limit holes are opened on both sides of the outer wall of the wind baffle. The self-locking rod is engaged with the limit holes, and anti-loosening gaskets are provided inside the limit holes.

[0010] Furthermore, a winding groove is provided on one side of the connecting sleeve, and the other end of the traction rope is fixed in the winding groove. A torque spring is installed in the winding groove of the connecting sleeve, one end of the torque spring is fixed to the inner wall of the winding groove, and the other end is connected to the fixed end of the traction rope.

[0011] Furthermore, a sealing rubber strip is provided on the inner wall of the front cover, and an anti-slip texture is provided on the surface of the wind deflector.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the anti-fall-off air conditioner outlet device with self-locking air guide plate is reasonable and has the following advantages:

[0013] (1) The self-locking component adopts an innovative two-way locking structure design, which consists of three parts: a limiting groove, a spring buckle, and an anti-loosening pad. When the wind deflector is closed, the self-locking rod will automatically embed into the limiting groove under the action of the elastic force to form a mechanical locking state. This design can effectively prevent the wind deflector from rotating accidentally, block debris and flying insects from entering, avoid children from accidentally touching it, and avoid angle deviation or loosening and falling off. Through special material treatment and structural optimization of the self-locking component, its fatigue resistance is significantly improved, greatly improving the stability and reliability of the air conditioning outlet device and extending the service life of the wind deflector. In addition, this design completely eliminates the safety hazards such as component damage and foreign object inhalation that may be caused by the wind deflector falling off accidentally, providing users with a safer and more stable user experience.

[0014] (2) An anti-fall adjustment component is set up. This component adopts a high-precision servo motor drive system and intelligent angle sensor linkage design. The built-in microprocessor monitors and adjusts the deflection angle of the wind deflector in real time. Compared with the traditional manual adjustment method, users can remotely control it through the air conditioner remote control or mobile APP. The system supports stepless adjustment within a range of 180 degrees, which greatly improves the convenience and accuracy of adjustment. It can fully meet different spatial layouts, seasonal needs and personalized usage scenarios. Symmetrical buffer springs are set on both sides of the wind deflector shaft. When the wind deflector is pushed by the wind, the buffer spring generates a reverse torque to offset the external force. The deformation of the elastic element generates a restoring force to offset the dynamic loads such as wind force and vibration, forming a second layer of protection. Attached Figure Description

[0021] 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.

[0022] Please see Figure 1-5 The present invention provides a technical solution as follows:

[0023] Example 1:

[0024] An anti-fall-off air conditioner vent device with a self-locking air guide plate includes an air conditioner body 1. A frame 2 is snap-fitted to the front of the air conditioner body 1, facilitating the installation and disassembly of the frame 2 and enabling convenient maintenance and repair of the air conditioner vent device. An air outlet channel 3 is installed inside the air conditioner body 1; its design directly affects the airflow performance. A front cover 4 is snap-fitted to the front of the frame 2, protecting the internal structure of the frame 2 and enhancing the aesthetics of the air conditioner vent device. A baffle 5 is pivotally connected to the inner wall of the frame 2, allowing it to rotate freely within a certain angle range, thus adjusting the direction of the airflow. A support frame 6 is installed inside the air conditioner body 1, providing support for the anti-fall-off adjustment component 7 and the self-locking component 8, ensuring stable installation and normal operation of each component. The anti-fall-off adjustment component 7 is installed inside the support frame 6, and the self-locking component 8 is installed on the other side of the support frame 6.

[0025] Furthermore, the internal components of the anti-fall adjustment assembly 7 include a drive motor 701, a lead screw 702, a guide rod 703, a sliding table 704, a balance bar 705, a buffer spring 706, a linkage rod 707, and a connecting sleeve 708. The drive motor 701 is mounted on the outer wall of the support frame 6, serving as a power source to provide power for the angle adjustment of the windshield 5. The output shaft of the drive motor 701 is fixedly connected to the lead screw 702 via a coupling, which ensures stable power transmission between the drive motor 701 and the lead screw 702. The sliding table 704 is threaded onto the outer wall of the lead screw 702. When the lead screw 702 rotates under the drive of the drive motor 701, the sliding table 704 moves linearly along the axial direction of the lead screw 702. A guide rod 703 is installed through one side of the sliding table 704. The guide rod 703 is parallel to the lead screw 702. The guide rod 703 guides the movement of the sliding table 704, ensuring that the sliding table 704 moves smoothly in a straight line and preventing the sliding table 704 from deviating or shaking during movement. A balance bar 705 is fixedly connected to the inner wall of the support frame 6. A buffer spring 706 is installed through the balance bar 705 and passes through the sliding table 704. The buffer spring 706 can buffer and dampen the movement of the sliding table 704, reducing the impact force generated by the movement. At the same time, the balance bar 705 can further improve the stability of the movement of the sliding table 704. The bottom pivot of the sliding table 704 is connected to a linkage rod 707. One end of the linkage rod 707 is fixedly connected to a connecting sleeve 708. The sliding table 704 is connected to the pivot of the baffle plate 5 through the linkage rod 707 and the connecting sleeve 708. When the sliding table 704 moves linearly on the lead screw 702, the baffle plate 5 can be driven to rotate around its pivot through the transmission of the linkage rod 707 and the connecting sleeve 708, thereby realizing the automatic adjustment of the angle of the baffle plate 5.

[0026] Furthermore, the self-locking assembly 8 internally includes a connecting block 801, a return spring 802, a self-locking rod 803, and a traction rope 804. One end of the support frame 6 is fixedly connected to the connecting block 801. The return spring 802 is installed inside the connecting block 801, and the self-locking rod 803 is fixedly connected inside the return spring 802. The self-locking rod 803 is fixedly secured in the internal groove of the connecting block 801 by the return spring 802. One end of the self-locking rod 803 is fixedly connected to the traction rope 804, and limit holes are provided on both outer walls of the wind deflector 5, with the self-locking rod 803 engaging with the limit holes. When the angle of the wind deflector 5 needs to be adjusted, the connecting sleeve 708 in the anti-fall adjustment assembly 7 rotates, and the self-locking rod 803 is pulled by the traction rope 804 to overcome the elastic force of the return spring 802, so that the self-locking rod 803 is disengaged from the limiting hole of the wind deflector 5. At this time, the wind deflector 5 can rotate freely. When the wind deflector 5 is closed, the connecting sleeve 708 rotates back, and under the elastic force of the return spring 802, the self-locking rod 803 is re-engaged into the limiting hole of the wind deflector 5, thereby locking the wind deflector 5 and preventing the wind deflector 5 from shifting in angle due to wind force during air conditioning operation.

[0027] Furthermore, a winding groove is provided on one side of the connecting sleeve 708, and the other end of the traction rope 804 is fixed in the winding groove. A torque spring is installed inside the winding groove of the connecting sleeve 708, with one end of the torque spring fixed to the inner wall of the winding groove and the other end connected to the fixed end of the traction rope 804. When the connecting sleeve 708 rotates to loosen the traction rope 804, the torque spring can automatically wind the traction rope 804 neatly, preventing the traction rope 804 from tangling or knotting, and ensuring the normal operation of the traction rope 804 in subsequent use.

[0028] A sealing rubber strip is provided on the inner wall of the front hood 4. The sealing rubber strip is distributed in a ring. When the frame 2 and the front hood 4 are engaged, the sealing rubber strip can effectively prevent the air conditioning air from leaking from the connection between the frame 2 and the front hood 4, improving air outlet efficiency and reducing noise transmission. The surface of the wind deflector 5 is provided with anti-slip texture. The anti-slip texture is distributed in a cross-grid pattern, which makes it easy for the user to manually adjust the angle of the wind deflector 5, and also increases the aesthetics of the surface of the wind deflector 5.

[0029] Working principle: In use, firstly, when the user needs to adjust the angle of the wind deflector 5, the drive motor 701 in the anti-fall adjustment assembly 7 is activated. The drive motor 701 drives the lead screw 702 to rotate through the coupling. When the lead screw 702 rotates, the sliding table 704, which is threadedly connected to the lead screw 702, will move linearly along the axial direction of the lead screw 702 under the guidance of the guide rod 703. At the same time as the sliding table 704 moves, the wind deflector 5 is driven to rotate around its axis through the linkage rod 707 and the connecting sleeve 708 connected to the bottom rotating shaft, thereby realizing the adjustment of the angle of the wind deflector 5.

[0030] Secondly, when the angle of the wind deflector 5 needs to be adjusted, the connecting sleeve 708 rotates, and the torque spring in the winding groove of the connecting sleeve 708 is compressed. At the same time, the self-locking rod 803 is pulled by the traction rope 804 to overcome the elastic force of the return spring 802, so that the self-locking rod 803 is disengaged from the limiting hole of the wind deflector 5. At this time, the wind deflector 5 can rotate freely. When the wind deflector 5 is closed, the drive motor 701 is turned off, the connecting sleeve 708 stops rotating, and under the elastic force of the return spring 802, the self-locking rod 803 is re-engaged into the limiting hole of the wind deflector 5 to lock the wind deflector 5. At the same time, under the action of the torque spring, the traction rope 804 is automatically wound neatly to prevent tangling and knotting.

[0031] Finally, if the user needs to manually adjust the angle of the wind deflector 5, the anti-fall adjustment component 7 is provided on the rear side of the wind deflector 5, which can be automatically adjusted. During the adjustment process, the self-locking rod 803 will also be pulled out of the limiting hole by the traction rope 804. After the adjustment is completed, since the inner wall of the front cover 4 is provided with a sealing rubber strip, after the frame 2 and the front cover 4 are engaged and connected, the air conditioner air outlet can be effectively prevented from leaking from the connection, ensuring the air conditioner's air outlet efficiency and performance.
