Description

Technical Field

[0001] The utility model belongs to the technical field of automobile parts, and in particular relates to a heteroaxial blade structure on a double-channel hidden air outlet. Background Art

[0002] Car air-conditioning vents are part of the car's interior decoration and are generally located on the main and auxiliary instrument panels. The dual-channel hidden air outlets ensure the original functions while making the air outlet operation simpler and more intelligent, and the interior layout more concise and comfortable. When the air-conditioning cooling or heating mode is turned on, the interior temperature can be adjusted. By adjusting the air outlet blades and changing the blowing direction, the appropriate wind speed and airflow with the appropriate temperature can be blown to the required area to meet the requirements for temperature airflow.

[0003] The two blade groups in the dual-channel hidden air outlet in the prior art are both coaxially arranged, and are driven to rotate by a single motor. Now, in order to hide the blade group deeper in the shell and not expose it to the user's field of vision, an improved design is being made. However, due to the structure of the outer shell of the air outlet, it is difficult for a single motor to effectively drive the two blade groups to rotate. Using dual motors to control the two blade groups separately will limit the installation of the drive elements, and the drive elements have a complex structure and many parts, which not only has a high manufacturing cost, but is also prone to damper failure.

[0027] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0028] like Figures 1 to 5 As shown, a heteroaxial blade structure on a dual-channel hidden air outlet includes: an outer shell 1, a diverter frame 2, a dial knob 3, a first air sweeping blade group 4 and a second air sweeping blade group 5.

[0029] Specifically, the outer shell 1 has an air inlet end 100 and an air outlet end, and the diverter frame 2 is arranged in the outer shell 1, and the diverter frame 2 divides the air outlet end of the outer shell 1 into a first air outlet channel 101 and a second air outlet channel 102. The wind sent into the air inlet end 100 can be sent out from the first air outlet channel 101 and the second air outlet channel 102 respectively, so that the air flow is blown to the required area, and the knob 3 is slidably arranged on the diverter frame 2 along the width direction (Y-axis direction) of the outer shell 1, and the knob 3 is provided with a first fork 300 and a second fork 301. In this embodiment, the first sweeping blade group 4 is located on the first air outlet channel 101, and the second sweeping blade group 5 is located on the second air outlet channel 102. The first air sweeping blade group 4 and the second air sweeping blade group 5 are arranged on different axes, so that the blades are hidden deeper and are invisible to the user in the outer shell 1. The first fork 300 is connected to the first air sweeping blade group 4, and the second fork 301 is connected to the second air sweeping blade group 5. Therefore, the user drives the first fork 300 and the second fork 301 to move by the knob 3 on the sliding diverter frame 2, so that the first air sweeping blade group 4 connected to the first fork 300 and the second air sweeping blade group 5 connected to the second fork 301 can achieve the function of synchronous left and right air guiding and closing, which not only simplifies the structure of the air outlet air guiding, but also reduces the space occupied by the overall air outlet in the car.

[0030] Specifically, Figure 3 and Figure 4 As shown, the first wind sweeping blade group 4 has a plurality of first rotating shafts 400, which are rotatably arranged on the outer shell 1 and the diverter frame 2, and each of the first rotating shafts 400 is provided with a first blade 401, and the first blade 401 is located in the first air outlet channel 101 near the air inlet end 100. The second wind sweeping blade group 5 has a plurality of second rotating shafts 500, which are rotatably arranged on the outer shell 1 and the diverter frame 2, and each of the second rotating shafts 500 is provided with a second blade 501, and the second blade 501 is located in the second air outlet channel 102 near the air inlet end 100. The central axis of the first rotating shaft 400 is parallel to the central axis of the second rotating shaft 500.

[0031] The first rotating shaft 400 is installed through the outer shell 1 and the diverter frame 2, ensuring that the first rotating shaft 400 can drive the first blade 401 to stably rotate left and right in the first air outlet channel 101, and the number of the first rotating shaft 400 is set according to the width of the first air outlet channel 101 to ensure the left and right wind guiding and closing functions are achieved. The second rotating shaft 500 is also installed through the outer shell 1 and the diverter frame 2, ensuring that the second rotating shaft 500 can drive the second blade 501 to stably rotate left and right in the second air outlet channel 102, and the number of the second rotating shaft 500 is also set according to the width of the second air outlet channel 102 to ensure the left and right wind guiding and closing functions are achieved. Due to the structure of the outer shell 1 of the air outlet, the central axis of the first rotating shaft 400 and the central axis of the second rotating shaft 500 are not colinear, and the off-axis installation is adopted to achieve the purpose of hiding the blades deeper and being invisible to the user in the outer shell 1.

[0032] Furthermore, if Figures 2 to 3 As shown, the first wind sweeping blade group 4 has a first connecting rod 402, which is connected to a plurality of first rotating shafts 400, the second wind sweeping blade group 5 has a second connecting rod 502, which is connected to a plurality of second rotating shafts 500, and the first fork 300 extends into the diverter frame 2 and is engaged with one of the first rotating shafts 400, and the second fork 301 extends into the diverter frame 2 and is engaged with one of the second rotating shafts 500.

[0033] A plurality of first rotating shafts 400 are connected by a first connecting rod 402, and one of the first rotating shafts 400 is connected to a first fork 300 extending into the diverter frame 2, and a plurality of second rotating shafts 500 are connected by a second connecting rod 502, and one of the second rotating shafts 500 is connected to a second fork 301 extending into the diverter frame 2, so that when a user slides the dial knob 3 on the diverter frame 2 to drive the first fork 300 and the second fork 301 to move, the first wind sweeping blade group 4 connected to the first fork 300 and the second wind sweeping blade group 5 connected to the second fork 301 can achieve the function of synchronously guiding the wind to the left and right and closing the wind.

[0034] Specifically, Figure 1 and Figure 2 As shown, the outer shell 1 has a left shell 103 and a right shell 104, a first slot 105 and a through hole 106 are provided on the periphery of the left shell 103, a first buckle 107 and a threaded hole 108 are provided on the periphery of the right shell 104, the first slot 105 is movably engaged with the first buckle 107, and the through hole 106 is connected with the threaded hole 108 by bolts.

[0035] The outer shell 1 is assembled by a left shell 103 and a right shell 104, so as to facilitate the installation and disassembly of the diverter frame 2, the first wind sweeping blade group 4 and the second wind sweeping blade group 5. In order to fix the left shell 103 and the right shell 104 to each other, a plurality of first slots 105 and a plurality of through holes 106 are arranged on the periphery of the left shell 103, and a plurality of first buckles 107 and a plurality of threaded holes 108 are correspondingly arranged on the periphery of the right shell 104. The first slots 105 are movably engaged with the first buckles 107, and after the through holes 106 are connected with the threaded holes 108, they are fixed by bolts.

[0036] Furthermore, if Figure 1 , Figure 2 and Figure 5 As shown, the peripheries of both ends of the diverter frame 2 abut against the outer shell 1 , and a second slot 200 is provided on the diverter frame 2 , and a second buckle 109 is provided on the right shell 104 , and the second slot 200 is engaged with the second buckle 109 .

[0037] The peripheries of both ends of the diverter frame 2 abut against the outer shell 1 to prevent the diverter frame 2 from moving relative to the outer shell 1 in the length direction (X-axis direction) and height direction (Z-axis direction). A plurality of second clips 109 are provided on the right shell 104, and a plurality of second slots 200 are provided on the diverter frame 2. The second slots 200 are engaged with the second clips 109, so that the diverter frame 2 cannot be displaced relative to the frame direction (Y-axis direction) of the outer shell 1, thereby fixing the diverter frame 2 in the outer shell 1, ensuring that the first sweeping blade group 4 can stably rotate in the first air outlet channel 101, and the second sweeping blade group 5 can stably rotate in the second air outlet channel 102.

[0038] Specifically, Figures 1 to 5 As shown, a limiting slot 201 is formed on the diverter frame 2 away from the air inlet end 100, and the limiting slot 201 is arranged along the width direction of the outer shell 1. The upper and lower grooves of the limiting slot 201 form guide portions 202. A frame 302 is arranged on the knob 3, and guide grooves 303 are arranged on the upper and lower sides of the frame 302. The guide portion 202 is slidably connected to the guide groove 303.

[0039] The frame 302 is in the limiting groove 201, and the guide grooves 303 on the upper and lower sides of the frame 302 are respectively movably connected with the guide parts 202 on the upper and lower sides of the limiting groove 201, to ensure that when the knob 3 drives the frame 302 to move on the limiting groove 201 along the width direction of the outer shell 1, the frame 302 will not be separated from the limiting groove 201, and can drive the first fork 300 and the second fork 301 to move synchronously.

[0040] Furthermore, if Figures 4 to 5As shown, the diverter frame 2 has a left half frame 203 and a right half frame 204 clamped with the left half frame 203, the two ends of the left half frame 203 are against the outer shell 1, and the right half frame 204 has an upper right half frame 205 and a lower right half frame 206, which are connected by bolts to form a limited position through groove 201.

[0041] The left half frame 203 and the right half frame 204 are assembled by means of slots and snap connections, and the right half frame 204 can be divided into an upper right half frame 205 and a lower right half frame 206. When installing the dial 3, the frame 302 can be first placed between the upper right half frame 205 and the lower right half frame 206 to ensure that after the upper right half frame 205 and the lower right half frame 206 are connected, the frame 302 is restricted in the limiting through groove 201, so that the subsequent sweeping action of the first sweeping blade group 4 and the second sweeping blade group 5 and the closing of the damper can be realized.
