Description

Technical Field

[0001] The present invention relates to the technical field of automobile accessories, and more specifically, to an automobile air-conditioning air outlet assembly. Background Art

[0002] The existing automobile air outlet assembly requires the fixed bracket (i.e., the dial frame), the dial wheel, and the damping ring to be stacked together in sequence and then tightened to a certain torque by screws to fix the dial wheel and achieve the damping effect. The above structure has the following disadvantages: 1) It requires high quality of the operator of the torque gun and strict accuracy of the torque gun; 2) There are many installation steps, and the dial wheel cannot be directly fixed to the fixed bracket. It is necessary to stack the fixed bracket, the dial wheel, and the damping ring, and then tighten them with screws, which makes manual assembly cumbersome. Summary of the invention

[0005] In the above technical solution, a first inclined surface is provided on one side of the first retaining rib and the second retaining rib, and a second inclined surface is provided on the end surface of the rotating shaft portion.

[0006] In the above technical solution, two groups of first protrusions are arranged at intervals on the outer peripheral wall of the dial wheel, a locking spring bracket is arranged in the dial wheel frame, a locking spring is fixedly arranged on the locking spring bracket, a second protrusion is arranged on the locking spring, and the second protrusion is located on the rotation path of the first protrusion.

[0007] In the above technical solution, a through hole facing the locking spring bracket is provided on the side wall of the dial frame, a fastener through hole is provided at the bottom of the dial frame, and a fastener is provided in the fastener through hole to fasten the locking spring to the locking spring bracket.

[0008] The present invention has the following beneficial effects: by adopting a convex rib structure in the dial wheel frame, the present invention can not only install the dial wheel in place in one step, but also has a self-damping feeling, omitting the damping ring and screws, and reducing the parts composition.

[0017] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: Figures 1 to 8 A car air outlet assembly with a dial damping mechanism includes an air outlet housing 2, wherein the air outlet housing 2 includes an air inlet 20 and an air outlet 21.

[0018] The air outlet housing 2 is rotatably provided with a damper cover plate 3 at the position of the air inlet 20, and the air outlet housing 2 is sequentially provided with a longitudinal swing blade group 6 and a transverse swing blade group 7 at the position of the air outlet 21. The longitudinal swing blade group 6 is provided in two groups at intervals, and the transverse swing blade group 7 is also provided in two groups at intervals. Each group of the longitudinal swing blade group 6 includes three longitudinal swing blades 60 rotatably provided at intervals, and each group of the transverse swing blade group 7 includes three transverse swing blades 70 rotatably provided at intervals. The transverse swing blades 70 of each group of transverse swing blade groups 7 are connected to each other through a transverse swing blade connecting rod 4. The longitudinal swing blades 60 of each group of longitudinal swing blade groups 6 are connected to each other through a longitudinal swing blade connecting rod 8.

[0019] A toggle knob 1 is slidably disposed on the middle transverse swing blade 70 of each transverse swing blade group 7. One end of the toggle knob 1 has a toggle slot 10, and a toggle rod 60a is disposed on the middle longitudinal swing blade 60 of each longitudinal swing blade group 6, and the toggle rod 60a is located in the toggle slot 10.

[0020] A thumbwheel mechanism 9 is disposed between the two longitudinal swing blade groups 6, and the thumbwheel mechanism 9 includes a thumbwheel frame 90, and a thumbwheel 91 is rotatably disposed in the thumbwheel frame 90. Specifically, the thumbwheel 91 has a rotating shaft portion 91a on both sides, and a rotating shaft seat 90a matching the rotating shaft portion 91a is disposed on two inner walls corresponding to the thumbwheel frame 90. The rotating shaft seat 90a includes two groups of first retaining ribs 900 disposed at a relative interval and a second retaining rib 901 disposed between the two first retaining ribs 900. A first inclined surface 100 is disposed on one side of the first retaining rib 900 and the second retaining rib 901, and a second inclined surface 100 is disposed on the end surface of the rotating shaft portion 90a. 01. In the above structure, the dial wheel 91 can be directly inserted into the dial wheel frame 90. At this time, through the cooperation of the first inclined surface and the second inclined surface, the dial wheel 91 will not be blocked by the first and second retaining ribs when inserted into the dial wheel frame 90, and when the dial wheel slides to its shaft seat 90a and is stuck in the shaft portion 91a surrounded by the first retaining rib 900 and the second retaining rib 901, its shaft portion 91a is limited. Through this structure, the three-sided surrounding shaft seat is matched with the shaft portion 91a of the impeller. While limiting the shaft portion 91a, the size between the shaft portion 91a and the first and second retaining ribs is controlled to achieve the technical effect of providing damping for the shaft portion 91a.

[0021] A connecting rod shaft 91 b is disposed at the rear end of the dial wheel 91 , and the damper cover plate 3 and the connecting rod shaft 91 b are transmission-connected via a dial wheel connecting rod 5 .

[0022] Two groups of first protrusions 91c are arranged at intervals on the outer peripheral wall of the dial wheel 91, and a locking spring bracket 90b is arranged in the dial frame 90, on which a locking spring 102 is fixedly arranged, and a second protrusion 102a is arranged on the locking spring bracket 90b, and the second protrusion 102a is located on the rotation path of the first protrusion 91c. In the above structure, when the dial wheel 91 rotates, the second protrusion 102a is squeezed by the first protrusion 91c when it rotates, so that the second protrusion 102a is elastically deformed, and the second protrusion 102a rebounds and hits the dial wheel to issue a prompt sound. The locking spring made of metal material has good fatigue resistance and durability, and the perceived prompt sound is crisp and loud.

[0023] Preferably, a through hole is provided on the side wall of the dial frame 90, which is opposite to the locking spring bracket 90b, and a fastener through hole is provided at the bottom of the dial frame 90 (not shown in the drawings). In the above structure, the locking spring 102 can be directly assembled on the locking spring bracket 90b after passing through the through hole, and then a fastener is provided in the fastener through hole to fasten the locking spring to the locking spring bracket.

[0024] The upper and lower ends of the wheel frame 90 are provided with locks 90, and the upper and lower side walls of the air outlet housing 2 are respectively provided with lock buckles 22. The two side walls of the wheel frame 90 are provided with shaft holes, and one end of the transverse swing blade 70 is rotatably matched with the shaft hole. The frame also includes a bracket plate 200, and the other end of the transverse swing blade 70 is rotatably matched with the bracket plate 200. In the above structure, the transverse swing blade, the wheel frame 90 and the bracket plate 200 can be pre-assembled, and the wheel 91 in the wheel frame 90 can also be pre-assembled, and then the above assembled parts are directly set in the air outlet housing 2, at which time the locks 90 at the upper and lower ends of the wheel frame 90 are buckled into the lock buckles 22 for fixing, and the bracket plate 200 and the air outlet housing 2 are fixed.

It should be understood by those skilled in the art that the present invention is not limited by the above embodiments. The above embodiments and descriptions in this application are only the principles of the present invention, and the present invention may have various changes and modifications without departing from the spirit and scope of the present invention. The above changes and modifications all fall within the scope of the present invention claimed.
