Description

Technical Field

[0001] The present invention relates to the field of automobile air vents, and particularly to an automobile air conditioner vent with a single vane for guiding air. Background Art

[0002] At present, in the air vents of automobile air conditioners in the automobile industry, the number of front row vanes is relatively large, generally about 3 - 6, or even more. As a result, the width of the air vent will be correspondingly larger. There are also a small number of air vents on the market with a width of about 30 mm. Even if there are such air vents, the air guiding performance of the air vents is very poor and cannot meet the requirements.

[0003] When designing the automobile instrument panel, the space of the instrument panel is limited. Therefore, it is bound to compress the space layout of other parts. When there is a conflict between performance and space, some performance requirements may be sacrificed. In addition, due to the large number of front row vanes, the manufacturing cost increases, and the stability of product quality is also difficult to control. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an automobile air conditioner vent with a single vane for guiding air, which has a simple structure. Through the optimization of the structure design, the air vent is designed to be narrower, leaving more design space for the instrument panel, making it easier to arrange the air vent structure. At the same time, it can effectively solve the problem of poor air guiding performance of the air vent, reduce the communication time of design and development, and reduce the development cost.

[0005] The technical solution adopted by the present invention to solve its technical problems is: to provide an automobile air conditioner vent with a single vane for guiding air, including an outer housing and a middle front row vane. A single - sheet middle front row vane is installed at the upper opening of the outer housing. A knob is installed in the middle of the middle front row vane, and one end passes through the outer housing and is connected to one end of a middle swing rod. On the inner side walls of both sides of the upper opening of the outer housing, upper guiding vanes parallel to the middle front row vane are closely arranged. The lower end of the upper guiding vane is rotatably connected to a lower guiding vane. One end of the upper guiding vane passes through the outer housing and is connected to one end of a side swing rod. The other end of the middle swing rod is rotatably connected to the middle of a connecting rod. Arc - shaped through - slots are symmetrically arranged at both ends of the connecting rod, and circular limiting through - slots extend from the outer ends of the arc - shaped through - slots. The protruding guiding part at the lower end of the side swing rod is embedded in the corresponding arc - shaped through - slots and circular limiting through - slots for sliding. A row of lower row vanes perpendicular to the middle front row vane is arranged on the lower side inside the outer housing. The lower end of the knob is connected to the middle lower row vane through a fork rod, and the lower row vanes are connected to each other through a side moving connecting rod.

[0006] Preferably, brackets parallel to the middle front row vane are arranged on both sides of the lower row vanes. The brackets are fixed on the outer housing, and both ends of the lower row vanes are rotatably connected to the brackets.

[0007] Further preferably, limiting blocks are symmetrically arranged on the outer side walls of the outer housing on both sides of the intermediate swing rod.

[0008] Beneficial effects: The present invention relates to an automobile air-conditioning air outlet with single-blade guidance, which has a simple structure. Through the optimization of the structural design, the single-blade design and the unique guiding vane design are adopted, making the air outlet narrower, leaving a larger design space for the instrument panel, and making it easier to arrange the air outlet structure. At the same time, it can effectively solve the problem of poor air guiding performance of the air outlet, reduce the communication time of design and development, and reduce the development cost.

[0019] The present invention will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of this application.

[0020] As Figures 1-9 shown, an embodiment of the present invention relates to an automotive air-conditioning air outlet with single-blade guidance, including a housing 1 and an intermediate front row blade 2. A single-piece intermediate front row blade 2 is installed at the upper opening of the housing 1. A knob 3 is installed in the middle of the intermediate front row blade 2, and one end passes through the housing 1 and is connected to one end of an intermediate swing rod 10. On the inner side walls of both sides of the upper opening of the housing 1, upper guide blades 13 parallel to the intermediate front row blade 2 are closely arranged. The lower end of the upper guide blade 13 is rotatably connected to a lower guide blade 14. One end of the upper guide blade 13 passes through the housing 1 and is connected to one end of a side swing rod 7. The other end of the intermediate swing rod 10 is rotatably connected to the middle of a connecting rod 4. Arc-shaped through grooves 8 are symmetrically arranged at both ends of the connecting rod 4. The outer ends of the arc-shaped through grooves 8 extend to form circular limiting through grooves 9. The protruding guiding part 6 at the lower end of the side swing rod 7 is embedded in the corresponding arc-shaped through grooves 8 and circular limiting through grooves 9 and slides. A row of lower row blades 11 perpendicular to the intermediate front row blade 2 are arranged on the lower side inside the housing 1. The lower end of the knob 3 is connected to the middle lower row blade 11 through a fork rod 16. The lower row blades 11 are connected to each other through a side moving connecting rod 17.

[0021] On both sides of the lower row blades 11, brackets 15 parallel to the intermediate front row blade 2 are arranged. The brackets 15 are fixed on the housing 1, and both ends of the lower row blades 11 are rotatably connected to the brackets 15.

[0022] Limit blocks 5 are symmetrically arranged on the outer side walls of the housing 1 on both sides of the intermediate swing rod 10.

[0023] As an embodiment of the present invention, as Figure 7 shown, the intermediate front row blade 2 is in the middle position, and the upper guide blade 13 and the lower guide blade 14 are closely attached to the inner side wall of the housing 1.

[0024] When the knob 3 is forced to be flipped downwards by hand, as Figure 8As shown, the upper guide vane 13 and the lower guide vane 14 located on the upper side do not move, while the middle swing rod 10 drives the connecting rod 4 to move upward, causing the protrusion guiding part 6 on the lower side swing rod 7 to slide into the circular limiting through groove 9 and driving the upper guide vane 13 at the lower end to rotate along with the middle front row blade 2. The lower guide vane 14 flips along with the rotation of the upper guide vane 13 and forms a certain angle with the upper guide vane 13. At this time, the protrusion guiding part 6 on the side swing rod 7 located on the upper side slides to the closed end of the arc-shaped through groove 8, realizing the downward guiding of the wind direction.

[0025] Similarly, as Figure 9 shown, when the dial button 3 is flipped upward forcefully by hand, the upper guide vane 13 and the lower guide vane 14 located on the upper side flip, realizing the upward guiding of the wind direction.

[0026] When it is necessary to adjust the left and right wind directions, the dial button 3 needs to be swung left and right, driving all the lower row blades 11 to swing left and right through the fork rod 16 and the moving connecting rod 17 to adjust the left and right wind directions.

[0027] The structure of the present invention is simple. Through the optimization of the structural design, the single blade design and the unique guide vane design are adopted, making the air outlet design narrower, leaving a larger design space for the instrument panel, making it easier to arrange the air outlet structure. At the same time, it can effectively solve the problem of poor air guiding performance of the air outlet, reduce the communication time of design and development, and reduce the development cost.
