Description

Technical Field

[0001] This application relates to the field of automotive air vent technology, and more particularly to a self-locking, multi-angle adjustable automotive air vent. Background Technology

[0002] Currently, automotive air conditioning vents are key components for directional airflow distribution within the vehicle cabin, and their angle adjustment function is crucial for improving driving and passenger comfort. Most mainstream automotive air conditioning vents on the market currently employ a blade-type structure, with the airflow direction adjusted manually by moving the blades or a dial. To ensure that the blades remain at the set angle after adjustment and to prevent displacement due to airflow impact or vehicle vibration, existing technologies typically employ friction plate damping structures or simple ratchet / locking mechanisms.

[0003] However, existing car air vents have the following defects: for example, the friction plate damping structure wears out severely and cannot lock the blades after a period of use; the ratchet / locking structure is often limited by the number of gears and cannot achieve stepless adjustment, resulting in poor performance. Utility Model Content

[0004] The purpose of this application is to provide a self-locking, multi-angle adjustable car air vent with a long service life and good performance.

[0005] To achieve the above objectives, this application provides a self-locking, multi-angle adjustable automotive air vent, comprising an outer frame assembly, a rotating frame, a magnetic ring, and an adjustable blade assembly. The inner side of the outer frame assembly has a spherical surface. The rotating frame is rotatably mounted on the inner side of the outer frame assembly, thus restricting the axial sliding of the rotating frame relative to the outer frame assembly and preventing it from sliding off the spherical surface. At least 10% of the length of the rotating frame is made of ferromagnetic material. The magnetic ring is fixedly mounted on the outer side of the outer frame assembly, attracting the rotating frame so that the outer side of the rotating frame is not freely located inside the spherical surface, but rather the ferromagnetic material of the rotating frame is close to the spherical surface, forming a stable frictional force to ensure that the rotating frame does not rotate when the vehicle is moving. The adjustable blade assembly is mounted on the inner side of the rotating frame, and the airflow guidance and adjustment in various directions are achieved based on the 360° rotation of the rotating frame and the blade oscillation of the adjustable blade assembly.

[0006] The magnetic ring attracts the ferromagnetic material of the rotating frame, so that the outer side of the rotating frame is not freely located inside the spherical surface, but the ferromagnetic material of the rotating frame is close to the spherical surface. A stable frictional force is formed between the rotating frame and the outer frame assembly, ensuring that the rotating frame will not rotate when the vehicle is moving. Compared with the friction pads designed in traditional installations, it can still be used normally after some wear, with a longer service life and better performance.

[0007] As a preferred embodiment, the outer frame assembly includes a main annular body, a mounting ring, and a rubber sleeve. An outer retaining ring is provided on the outer side of the main annular body near the front end, and a rubber sleeve is bonded or fixedly fastened to the inner side of the main annular body near the front end. The rubber sleeve is used to cover the gap portion on the side of the adjustable blade assembly. The mounting ring is threaded to the outer rear end of the main annular body, and a clamping area is formed between the mounting ring and the outer retaining ring. This design facilitates the installation of the outer frame assembly in the pre-drilled hole of the air outlet on the vehicle body.

[0008] As a preferred embodiment, the rotating frame includes a first arc segment and a second arc segment. The first arc segment occupies at least 75% of the entire circle to ensure the stability of the main structure of the first arc segment. The second arc segment and the first arc segment form a complete ring. The second arc segment is made of ferromagnetic material. A stepped opening is provided at the end of the second arc segment. The second arc segment can squeeze outward to restrict the first arc segment. This design can prevent the first arc segment and the second arc segment from separating and facilitates the installation of the first arc segment and the second arc segment inside the outer frame assembly.

[0009] As another preferred embodiment, the adjustable blade assembly includes a main frame, several blade components, a linkage kit, an arc-shaped slide rail, and an arc-shaped frame. One end of the main frame is fixedly connected to the inner side of the second arc segment, and the main frame is arranged along the diameter direction of the second arc segment and the first arc segment forming a complete ring. The blade components are rotatably connected to the main frame, and an arc-shaped frame is fixedly provided on the side of the blade component. An arc-shaped slide rail corresponding to the arc-shaped frame is provided on the main frame, and the end of the arc-shaped frame is slidably engaged with the arc-shaped slide rail. The linkage kit is rotatably connected to the ends of the arc-shaped frames corresponding to the several blade components.

[0010] The blade component is rotatably connected to the main frame, and the arc frame and arc slide are designed to restrict the rotation between the blade component and the main frame. The design of the above two parts makes the blade component not easy to rotate. The user can hold the blade component and rotate it. When the user releases the blade component, the two parts can maintain the stability of the blade component by friction.

[0011] Further preferably, the end of the blade piece is fitted with the inner side of the rotating frame, for example, the outer ends of several blade pieces form a circle.

[0012] Further preferably, the cross-section of the linkage assembly is U-shaped, and the linkage assembly slides with the main frame, making the connection of the linkage assembly more stable and reducing the deformation of the linkage assembly under unbalanced forces during operation.

[0013] In a further preferred embodiment, a connecting member is fixedly provided at the bottom of the blade component, and the connecting member is rotatably connected to the main frame to maintain a gap between the blade component and the main frame, thereby avoiding interference with the rotation of the blade component.

[0014] Further preferably, a control block is fixedly provided on the blade component located in the middle, so that the user can control the rotation of the blade component by pinching the control block.

[0015] Compared with the prior art, the beneficial effects of this application are as follows: (1) This application is based on the magnetic ring attracting the ferromagnetic material part of the rotating frame, so that the outer side of the rotating frame is not freely located on the inner side of the spherical surface, but the ferromagnetic material of the rotating frame is close to the spherical surface, and a stable frictional force is formed between the rotating frame and the outer frame assembly, ensuring that the rotating frame will not rotate when the vehicle is moving. Compared with the traditional installation design of friction pads, it can still be used normally after some wear, with a longer service life and better performance. (2) By designing the rotating frame as a first arc segment and a second arc segment, the second arc segment and the first arc segment form a complete ring. The end of the second arc segment is provided with a step opening. The second arc segment can squeeze outward to restrict the first arc segment. This design can prevent the first arc segment and the second arc segment from separating and facilitates the installation of the first arc segment and the second arc segment inside the outer frame assembly.

[0025] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0026] like Figure 1-5 The self-locking, multi-angle adjustable car air vent shown includes an outer frame assembly 1, a rotating frame 3, a magnetic ring 5, and an adjustable blade assembly 4. The inner side of the outer frame assembly 1 has a spherical surface 2. The rotating frame 3 is rotatably mounted on the inner side of the outer frame assembly 1, thus limiting the axial sliding of the rotating frame 3 relative to the outer frame assembly 1 and preventing it from sliding out of the spherical surface 2. At least 10% of the length of the rotating frame 3 is made of ferromagnetic material. The magnetic ring 5 is fixedly mounted on the outer side of the outer frame assembly 1. The magnetic ring 5 attracts the rotating frame 3, ensuring that the outer side of the rotating frame 3 is not freely located inside the spherical surface 2, but rather that the ferromagnetic material of the rotating frame 3 is close to the spherical surface 2, forming a stable frictional force. This ensures that the rotating frame 3 will not rotate when the vehicle is moving. The adjustable blade assembly 4 is mounted on the inner side of the rotating frame 3. Based on the 360° rotation of the rotating frame 3 and the oscillation of the blades in the adjustable blade assembly 4, airflow guidance and adjustment in various directions can be achieved.

[0027] The magnetic ring 5 attracts the ferromagnetic material of the rotating frame 3, so that the outer side of the rotating frame 3 is not freely located inside the spherical surface 2, but the ferromagnetic material of the rotating frame 3 is close to the spherical surface 2. A stable frictional force is formed between the rotating frame 3 and the outer frame assembly 1, ensuring that the rotating frame 3 will not rotate when the vehicle is moving. Compared with the friction pads designed in traditional installations, it can still be used normally after some wear, with a longer service life and better performance.

[0028] In one embodiment, the outer frame assembly 1 includes a main annular body 101, a mounting ring 102, and a rubber sleeve 103. An outer retaining ring is provided on the outer side of the main annular body 101 near the front end, and the rubber sleeve 103 is bonded or fixedly fastened to the inner side of the main annular body 101 near the front end. The rubber sleeve 103 is used to cover the gap on the side of the adjustable blade assembly 4. The mounting ring 102 is threaded to the outer rear end of the main annular body 101, and a clamping area is formed between the mounting ring 102 and the outer retaining ring. This design makes it easy to install the outer frame assembly 1 in the air outlet reserved hole of the vehicle body.

[0029] In one embodiment, the rotating frame 3 includes a first arc segment 301 and a second arc segment 302. The first arc segment 301 occupies at least 75% of the entire circle to ensure the stability of the main structure of the first arc segment 301. The second arc segment 302 and the first arc segment 301 form a complete ring. The second arc segment 302 is made of ferromagnetic material. A stepped opening 3021 is provided at the end of the second arc segment 302. The second arc segment 302 can squeeze outward to restrict the first arc segment 301. This design can prevent the first arc segment 301 and the second arc segment 302 from separating and facilitates the installation of the first arc segment 301 and the second arc segment 302 inside the outer frame assembly 1.

[0030] In one embodiment, the adjustable blade assembly 4 includes a main frame 401, a plurality of blade pieces 404, a linkage kit 402, an arc-shaped slide rail 403, and an arc-shaped frame 405. One end of the main frame 401 is fixedly connected to the inner side of the second arc-shaped segment 302, and the main frame 401 is arranged along the diameter direction of the second arc-shaped segment 302 and the first arc-shaped segment 301 forming a complete ring. The blade pieces 404 are rotatably connected to the main frame 401, and the side of the blade pieces 404 is fixedly provided with an arc-shaped frame 405. The main frame 401 is provided with an arc-shaped slide rail 403 corresponding to the arc-shaped frame 405. The end of the arc-shaped frame 405 is slidably engaged with the arc-shaped slide rail 403. The linkage kit 402 is rotatably connected to the end of the arc-shaped frame 405 corresponding to the plurality of blade pieces 404.

[0031] The blade component 404 is rotatably connected to the main frame 401, and the arc frame 405 and the arc slide 403 are designed to slide together to restrict the rotation between the blade component 404 and the main frame 401. The design of the above two parts makes the blade component 404 difficult to rotate easily. The user can hold the blade component 404 and rotate it. When released, the two parts can rely on friction to keep the blade component 404 stable. The end of the blade component 404 is engaged with the inner side of the rotating frame 3. For example, the outer ends of several blade components 404 form a circle.

[0032] In one embodiment, the linkage assembly 402 has a U-shaped cross section and slides with the main frame 401; this makes the connection of the linkage assembly 402 more stable and reduces the deformation of the linkage assembly 402 under unbalanced forces during operation. In another embodiment, a connecting member 4042 is fixedly provided at the bottom of the blade 404, and the connecting member 4042 is rotatably connected to the main frame 401, so as to maintain a gap between the blade 404 and the main frame 401 and avoid interfering with the rotation of the blade 404. An operating block 4041 is fixedly provided on the blade 404 located in the middle, so that the user can pinch the operating block 4041 to control the rotation of the blade 404.

[0033] Working principle: When in use, the user can rotate the rotating frame 3 and the adjustable blade assembly 4 as a whole, and adjust the tilt angle of the blades of the adjustable blade assembly 4 to achieve airflow adjustment in any direction; after rotating and adjusting the rotating frame 3, the magnetic ring 5 attracts the ferromagnetic material part of the rotating frame 3, so that the outer side of the rotating frame 3 is not freely located inside the spherical part 2, but the ferromagnetic material of the rotating frame 3 is close to the spherical part 2, and a stable frictional force is formed between the rotating frame 3 and the outer frame assembly 1, ensuring that the rotating frame 3 will not rotate when the vehicle is moving.

Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
