Description

Technical Field

[0001] The invention relates to the technical field of automobile air outlets, and in particular to an automobile air outlet assembly and an assembly method. Background Art

[0002] Car air-conditioning vents are car interior components and are generally located on the dashboard of the car's center console. The most common air outlet structure is a grille structure, which generally includes an air outlet housing, a vertical blade group, a horizontal blade group, a damper, a dial transmission mechanism, etc. When in use, the horizontal blades and vertical blades are driven by the dial button to adjust the opening direction and angle of the vertical blades and horizontal blades, thereby adjusting the air outlet direction of the air conditioner.

[0003] The blades of the grille-type air outlet are distributed in parallel. The two ends of the blades are hinged on two connecting rods at the same time. When one of the blades is moved, the remaining blades are linked to the movement through the connecting rod, so that multiple blades can move up and down at the same time. However, this blade distribution method is relatively cumbersome and difficult to assemble. When adjusting this type of blade, only one of the blades is active, and the remaining blades are driven to move through the connecting rod. There is a certain damping between the blade and the connecting rod, which will cause the connecting rod structure to be subjected to greater force and easy to be damaged. Therefore, the current pursuit of integrated air outlet blades is to reduce the workload of assembly.

[0004] Although the integrated blades are simple, the blades on the upper and lower sides will rotate together with the axis in the middle, which makes the overall range of motion of the blades larger, causing the movement of the blades to interfere with and collide with the shell, so the pitch angle is relatively small and cannot meet the adjustment requirements. For example, in the air outlet structure shown in references 1 and 2, the existing integrated air outlet blades are usually blades with an integrated middle part, and the upper and lower ends are set to be blades linked to the middle, thereby increasing the pitch angle of the air conditioner outlet, so that the pitch process of the air outlet blades is not restricted by the shell, but its assembly is still not convenient enough.

[0045] In order to better understand the technical content of the present invention, specific embodiments are given and described as follows in conjunction with the accompanying drawings.

[0046] Various aspects of the invention are described in this disclosure with reference to the accompanying drawings, in which many illustrative embodiments are shown. The embodiments of the present disclosure are not necessarily intended to include all aspects of the invention. It should be understood that the various concepts and embodiments introduced above, as well as those described in more detail below, can be implemented in any automotive air outlet assembly in many ways, because the concepts and embodiments disclosed in the present invention are not limited to any implementation. In addition, some aspects of the present disclosure can be used alone or in any appropriate combination with other aspects of the present disclosure.

[0047] The automobile air outlet assembly shown in the present invention is mainly used for the front or rear air conditioning outlets in passenger cars to guide the automobile air conditioning wind to make passengers more comfortable. It adopts an integrated air guide blade to simplify the assembly steps, reduce the assembly difficulty, and make the overall structure of the blade high in strength and not easy to be damaged.

[0048] Combination Figure 1 and Figure 2 As shown, the present invention provides an automobile air outlet assembly, comprising an air outlet housing 1 , an integrated front blade 3 , a rear blade 4 and a dial button 2 .

[0049] The air outlet housing 1 adopts a two-stage structure, the front and rear shells are both injection molded and clamped together by a clamping structure, and an assembly buckle 12 is fixedly provided on the outer wall, which can be clamped into the vehicle, and an air outlet window 101 is provided on the front side thereof, and a first active cavity 102 and a second active cavity 103 are sequentially arranged inside from front to back, which are used to accommodate the integrated front blade 3 and the rear blade 4 respectively;

[0050] Furthermore, the integrated front blade 3 is horizontally installed in the first active cavity 102, and can be rotated to adjust the wind direction. The button 2 is fixedly installed on the integrated front blade 3. The user can move the button 2 up and down by hand to make the integrated front blade 3 rotate up and down at a certain pitch angle on the air outlet housing 1 to adjust the direction of the blown wind.

[0051]

Integrated front blade 3

[0052] Combination Figure 3 and Figure 4 As shown, the integrated front blade 3 includes an integrated first blade 31 , a second blade 32 and a support blade 33 .

[0053] The first blade 31 includes a receiving section 314 and connecting sections 313 symmetrically arranged at both ends of the receiving section 314 , the two ends of the two connecting sections 313 are respectively fixed with a solid shaft 311 and an elastic clamping shaft 312 , and the receiving section 314 protrudes forward from the air outlet window 101 .

[0054] In a preferred embodiment, the angle between the connecting section 313 and the straight line including the solid shaft 311 and the elastic clamping shaft 312 is 15°~45°, which can reduce the restriction of the first blade 31 on the air outlet housing 1 during its pitch rotation and is less likely to cause collision, thus allowing the first blade 31 to have a larger pitch angle.

[0055] In this way, the solid shaft 311 and the elastic clamping shaft 312 are located on the same axis, and the first blade 31 can rotate around the solid shaft 311 and the elastic clamping shaft 312, which not only plays a role in guiding wind, but also provides an installation environment for the second blade 32 and the bracket blade 33.

[0056] In an optional embodiment, the first blade 31 includes a single-layer blade or a plurality of blades distributed in parallel in an integrated manner. The number of the first blades 31 can be selected according to the area of ​​the air outlet window 101, and the total number of blades of the air outlet window 101 is controlled to be less than or equal to five, so that the integrated front blade 3 has a larger pitch angle, a good ability to adjust the wind guide angle, and a beautiful appearance.

[0057] Furthermore, a first axial hole 104 and a second axial hole 105 are respectively formed at both ends of the inner side wall of the first movable cavity 102 in the horizontal direction. The solid shaft 311 is rotatably installed in the first axial hole 104 , and the elastic clamping shaft 312 is rotatably installed in the second axial hole 105 .

[0058] Combination Figure 7 As shown, the elastic clamping shaft 312 passes through the second axial hole 105 to one end of the outside of the air outlet shell 1, and is clamped and installed with a damping lever 34. A damping clamping strip 11 that cooperates with the damping lever 34 is fixedly installed on the outer wall of the air outlet shell 1. The damping clamping strip 11 is made of rubber material, and has multiple flange structures on the side facing the damping lever 34. When the damping lever 34 rotates, it will contact and rub with the flange structure, which can bring a segmented damping feeling and facilitate users to adjust the angle.

[0059] Combination Figure 3-Figure 6 As shown, in order to make the overall structure of the integrated front blade 3 more stable and easier to assemble while taking into account better pitch wind guide adjustment capabilities, parallel distributed second blades 32 are set on the upper and lower sides of the first blade 31 and are located on the rear side of the first blade 31. The bracket blade 33 is used to fix the first blade 31 and the second blade 32.

[0060] Among them, the bracket blade 33 includes a first receiving section 331 and a second receiving section 332 symmetrically arranged at both ends of the first receiving section 331. The first receiving section 331 is fixed on the upper and lower sides of the first blade 31, and the second receiving section 332 extends in a direction away from the first blade 31. The second blade 32 is fixedly installed on the inner side of the two second receiving sections 332 on the same side.

[0061] Furthermore, the second blades 32 include single-layer blades or multi-layer blades distributed in parallel in an integrated manner, and the number of the second blades 32 can be selected according to the area of ​​the air outlet window 101, and the total number of blades of the air outlet window 101 is controlled to be less than or equal to five, so that the integrated front blade 3 has a larger pitch angle, good ability to adjust the wind guide angle, and beautiful appearance.

[0062] In an optional embodiment, along the axial direction of the solid shaft 311 and the elastic clamping shaft 312, the angle between the second receiving section 332 and the first blade 31 is 30°~90°, and perpendicular to the axial direction of the solid shaft 311 and the elastic clamping shaft 312, the angle between the second receiving section 332 and the first blade 31 is 45°~75°. According to the cross-sectional shape of the air outlet window 101, the length of the second blade 32 can be equal to or less than the length of the first blade 31. The angle between the second receiving section 332 and the first blade 31 is selected under the premise of stable and beautiful structure.

[0063] Combination Figure 7-10 As shown, in a preferred embodiment, the air outlet side of the air outlet housing 1 is defined as the front side, the air inlet side of the air outlet housing 1 is defined as the rear side, the integrated front blade 3 reaches the maximum elevation position as the first position, and the integrated front blade 3 reaches the maximum depression position as the second position.

[0064] The height of the air inlet side of the air outlet housing 1 is lower than that of the air outlet side, and its top surface is raised 15° toward the front, and its bottom surface extends forward 2-3 cm, so that the top surface and the bottom surface port form a 75° slope.

[0065] Furthermore, the first blade 31 is a single-layer blade, which is placed in the middle of the height direction of the air outlet window 101, and the solid shaft 311 and the elastic clamp shaft 312 at both ends are installed at the front end of the first active cavity 102, so that most of the receiving section 314 protrudes from the air outlet window 101;

[0066] The second blade 32 adopts an integrated double-blade structure and is installed on the inner side of the bracket blade 33. The angle between the second receiving section 332 and the first blade 31 is 45°, so that the axial line connecting the first blade 31 and the second blade 32 forms a cone tip shape, and the width of the upper second blade 32 is smaller than that of the lower second blade 32, and both are smaller than the width of the first blade 31. When in use, the upper second blade 32 is tilted backward by a greater amplitude of 45°, and the lower second blade 32 is tilted backward by 60°, so that the angle of the integrated front blade 3 in the first position is 45° upward, and the angle in the second position is 45° downward.

[0067] In this way, the integrated front blade 3 will not come into contact with the air outlet housing 1 when moving between the first position and the second position, and the overall structure of the integrated front blade 3 is more compact and three-dimensional, so it has a beautiful appearance and high structural strength.

[0068] Furthermore, the second blade 32 located on the upper and lower sides of the first blade 31 is located in the same plane as the solid shaft 311 and the elastic clamping shaft 312, so that the integrated front blade 3 as a whole forms a conical structure on the side, so that the integrated front blade 3 has a larger pitch angle on the inner side of the first active cavity 102, so that the integrated front blade 3 has a large adjustment range and a strong wind guiding ability.

[0069] Specifically, mutually interpenetrating dial button mounting holes 301 are provided at the middle positions of the bracket blade 33 and the first blade 31 , and the dial button 2 is snap-fitted and mounted on the dial button mounting hole 301 . The user can manually turn the dial button 2 to adjust the wind guide angle of the integrated front blade 3 .

[0070] In combination with the above embodiments, only one integrated front blade 3 is installed in the first active cavity 102 of the air outlet housing 1. The structural design of the integrated front blade 3 only adopts a single-axis rotation method to control the rotation of the entire integrated blade, thereby simplifying the assembly steps and reducing the difficulty of assembly. At the same time, since the front blade structure is integrally formed, the blade as a whole is more stable and strong, and there will be no transmission failure or damage. In addition, the front blade structure is in a three-dimensional cone shape, which makes the pitch angle of the blade in the air outlet housing 1 larger. Therefore, the ability to adjust the wind guide angle is also correspondingly enhanced without affecting the normal use of the user.

[0071] The second aspect of the present invention proposes a technical solution

[0072] A method for assembling an automobile air outlet assembly comprises the following steps:

[0073] Step S1, injection molding accessories: using an injection mold to injection mold the air outlet housing 1, the dial button 2 and the integrated front blade 3, wherein the air outlet housing 1 and the dial button 2 are clamped and molded after injection molding, and the integrated front blade 3 is integrally injection molded, which can save the step of pre-assembling the current multi-blade structure into a linkage state, thereby simplifying the assembly steps;

[0074] Step S2, assemble the air outlet shell 1: the air outlet shell 1 includes two parts, a front part and a rear part, which are snap-fitted and fixed in advance, and then the rear blade 4 is vertically installed in the second movable cavity 103, and can be rotated left and right to adjust the wind direction. The damping clip 11 is installed on the outer wall of the air outlet shell 1 corresponding to the second axial hole 105. When the user turns the button 2, the damping lever 34 rotates with it and will contact and rub with the flange structure, which can bring a segmented damping feeling and facilitate the user to adjust the angle.

[0075] The rear blade 4 adopts an integrated or split blade structure. The integrated blade structure is similar to the integrated front blade 3 structure, with multiple vertically distributed blades arranged in the transverse direction. The split blade structure is arranged in the same manner as the existing split blades.

[0076] Step S3, assembling the dial button 2: The dial button 2 includes a clamping block that can be clamped up and down, and the two clamping blocks are clamped into the dial button mounting hole 301 on the integrated front blade 3 from the upper and lower sides respectively, so that the dial button 2 is fixed to the integrated front blade 3, which is easy to install;

[0077] Step S4, assembling the integrated front blade 3: then assemble the integrated front blade 3 with the button 2 onto the air outlet housing 1, first insert the solid shaft 311 into the first shaft hole 104, then insert the elastic clamping shaft 312 at the other end into the second shaft hole 105, and install the damping lever 34 at the end of the elastic clamping shaft 312, so that the damping lever 34 cooperates with the damping clamping strip 11 to form a damped rotating structure. Since the integrated front blade 3 has a stronger structure and only one pair of rotating shafts is installed, the difficulty of installation and the number of installation steps can be greatly reduced, thereby improving the assembly speed of this link.

[0078] In summary, the use of the integrated front blade 3 assembly method can significantly reduce the number of assembly steps and the difficulty of assembly, thereby improving the assembly speed and efficiency of this assembly link.

[0079] Although the present invention has been disclosed as above with preferred embodiments, it is not intended to limit the present invention.
