Technical Field

[0001] This utility model belongs to the technical field of automobile manufacturing, and in particular relates to an automobile air conditioning vent with automatically adjustable airflow direction. Background Technology

[0002] The air vents for car air conditioning are usually located on the right side of the center console, but the exact location may vary depending on the model. On some models, the vents may be located in the center or on either side of the dashboard. The air intakes are generally located below the rear windshield wipers in the front compartment to ensure effective air circulation and purification inside the vehicle.

[0003] The function of a car's air conditioning system is not only to regulate temperature, but also to create a comfortable riding environment for the driver, reduce travel fatigue, and provide good working conditions, thereby ensuring driving safety. The entire car air conditioning system includes cooling, heating, and ventilation components, which work together to ensure that the air quality and temperature inside the cabin are at their optimal levels.

[0004] The existing air vents require manual adjustment to change the airflow direction. While driving, the driver manually moves the grille to change the up-down and left-right airflow direction from the air vents. This manual operation is not only time-consuming and laborious, but it also affects the driver's driving and poses potential safety hazards. Utility Model Content

[0005] The purpose of this invention is to provide an automotive air conditioning vent with automatically adjustable airflow direction, which can automatically adjust the direction of the air outlet and effectively solve the safety hazard problem caused by manually moving the grille in the prior art.

[0006] This utility model adopts the following technical solution: an automatically adjustable car air conditioning vent, installed on the dashboard, includes an outer cover, which is fixedly installed on the dashboard. An inner cover is rotatably connected to the outer cover. Several wind deflectors are arranged vertically inside the inner cover, and each wind deflector is rotatably connected to the inner cover. A synchronization device is provided between adjacent wind deflectors. When one wind deflector rotates, the synchronization device drives the other wind deflectors to rotate synchronously. A driving device is fixedly installed on the outer surface of the outer cover. A transmission device is provided between the driving device and the synchronization device. The driving device drives the wind deflectors to reciprocate through the transmission device. Each wind deflector reciprocates synchronously under the action of the synchronization device; at the same time, the transmission device drives the inner cover to reciprocate.

[0007] Furthermore, the transmission device includes a drive disc hinged to the corresponding wind deflector, the rear side of the drive disc having a drive groove in the vertical direction, the drive device including a motor fixedly mounted to the outer cover, the output shaft of the motor having a radial rod fixedly mounted, the outer end of the radial rod having a drive rod fixedly mounted, and the drive rod being located in the drive groove.

[0008] Furthermore, the radial rod and the output shaft of the motor have a certain angle α, the hinge axis of the inner cover and the outer cover are in the same plane as the output shaft of the motor, and the motor drives the drive rod to rotate through the radial rod.

[0009] Furthermore, a torsion spring is sleeved on the hinge shaft of the inner and outer covers. One end of the torsion spring is fixed to the outer cover, and the other end of the torsion spring is fixed to the inner cover. The torsion spring drives the inner cover to rotate clockwise at all times.

[0010] Furthermore, the outer surface of the outer cover is provided with several air inlets.

[0011] Furthermore, the synchronization device includes two hinged rods that are hinged to each other between adjacent wind deflectors, with the outer end of each hinged rod hinged to the corresponding wind deflector.

[0012] Furthermore, a vertical rod is hinged to the front side of the drive disc, and the vertical rod is fixedly installed with the corresponding wind deflector.

[0013] Furthermore, each wind deflector is provided with a clearance groove at the position corresponding to the hinge rod.

[0014] Furthermore, each of the aforementioned wind deflectors is fixedly provided with a vertical shaft along the vertical direction, and the vertical shaft is rotatably connected to the inner cover.

[0015] Furthermore, a fixing plate is fixedly installed on the outer surface of the outer cover, and the motor is fixedly installed with the fixing plate.

[0016] I. This utility model sets up an inner cover, a wind deflector, a drive device and a transmission device. When this device is in use, the air conditioning air blows out from the inner cover. The drive device drives the wind deflector to rotate back and forth through the transmission device, so as to realize the purpose of the wind direction swinging back and forth in the left and right directions [1]. The transmission device drives the inner cover to rotate back and forth at the same time. The inner cover rotates back and forth to realize the wind direction swinging back and forth in the up and down directions, so that the air vents can scan the interior space of the car and blow air. This achieves the purpose of automatically adjusting the exhaust air direction of the air vents.

[0017] II. By setting up a motor, a radial rod, a drive rod, and a drive disc, when this device is in use, the motor drives the radial rod to rotate, and the radial rod drives the drive rod to revolve around the output shaft of the motor, so that the drive rod drives the drive disc to move back and forth in the left and right directions through the drive groove, so that the wind deflector rotates back and forth, thereby achieving the purpose of changing the wind direction back and forth in the left and right directions.

[0027] Please see Figure 1-8 The present invention will now be described in detail with reference to the accompanying drawings and embodiments:

[0028] The automatically adjustable airflow vent for automotive air conditioning, as described in this utility model, is mounted on the dashboard 1 and includes an outer cover 2, which is fixedly mounted on the dashboard 1. An inner cover 3 is rotatably connected inside the outer cover 2. Several wind deflectors 4 are vertically arranged inside the inner cover 3, and each wind deflector 4 is rotatably connected to the inner cover 3. A synchronization device is provided between adjacent wind deflectors 4. When one wind deflector 4 rotates, the synchronization device drives the other wind deflectors 4 to rotate synchronously. A driving device is fixedly mounted on the outer surface of the outer cover 2, and a transmission device is provided between the driving device and the synchronization device. The driving device drives the wind deflectors 4 to reciprocate through the transmission device. Each wind deflector 4 reciprocates synchronously under the action of the synchronization device. The rotation of the wind deflectors 4 adjusts the airflow direction in the left-right direction. At the same time, the transmission device drives the inner cover 3 to reciprocate, and the rotation of the inner cover 3 adjusts the airflow direction in the up-down direction.

[0029] During normal use, the air conditioning air blows out from the inner cover 3. The drive device drives the wind deflector 4 to rotate back and forth through the transmission device. Each wind deflector 4 rotates synchronously under the limit of the synchronization device, so that the air direction swings back and forth in the left and right directions. At the same time, the transmission device drives the inner cover 3 to rotate back and forth. The reciprocating rotation of the inner cover 3 makes the air direction swing back and forth in the up and down directions, so that the air vents can scan the interior space of the car. The dashboard 1 is equipped with a button to control the start and stop of the motor 7. When the motor 7 stops, the air vents blow air in a directional direction.

[0030] In this embodiment, the transmission device includes a drive disc 5 hinged to the corresponding wind deflector 4. The rear side of the drive disc 5 has a drive groove 6 in the vertical direction. The drive device includes a motor 7 fixedly mounted to the outer cover 2. A radial rod 8 is fixedly mounted on the output shaft of the motor 7. A drive rod 9 is fixedly mounted on the outer end of the radial rod 8. The drive rod 9 is located in the drive groove 6. The motor 7 drives the radial rod 8 to rotate, and the radial rod 8 drives the drive rod 9 to revolve around the output shaft of the motor 7. This causes the drive rod 9 to drive the drive disc 5 to move back and forth in the left and right direction through the drive groove 6, causing the wind deflector 4 to rotate back and forth, thereby achieving the purpose of changing the wind direction back and forth in the left and right directions.

[0031] Please see Figure 6 In this embodiment, the angle between the radial rod 8 and the output shaft of the motor 7 is α, where 90 degrees < α < 180 degrees. The hinge shaft 10 of the inner cover 3 and the outer cover 2 is in the same plane as the output shaft of the motor 7. The motor 7 drives the drive rod 9 to rotate through the radial rod 8. When the drive rod 9 is below the hinge shaft 10, the outer end of the radial rod 8 extends to the right and forward, causing the drive rod 9 to push the inner cover 3 to rotate through the drive disc 5, causing the outer side of the inner hole of the inner cover 3 to tilt upward. When the drive rod 9 is above the hinge shaft 10, the same principle applies, causing the drive rod 9 to push the inner cover 3 to rotate in the opposite direction through the drive disc 5, causing the outer side of the inner hole of the inner cover 3 to tilt downward. This achieves the purpose of the air vent swinging back and forth in the up and down direction. When used in conjunction with the baffle plate 4, it enables the air vent to swing back and forth in the left and right direction and in the up and down direction, achieving the purpose of scanning and blowing air into the interior of the car.

[0032] In this embodiment, a torsion spring 11 is sleeved on the hinge shaft 10 of the inner cover 3 and the outer cover 2. One end of the torsion spring 11 is fixedly set to the outer cover 2, and the other end of the torsion spring 11 is fixedly set to the inner cover 3. The torsion spring 11 drives the inner cover 3 to rotate clockwise at all times, so that the inner cover 3 drives the drive disk 5 to rotate clockwise at all times through the wind baffle 4, so that the inner bottom wall of the drive groove 6 of the drive disk 5 always abuts against the outer end of the drive rod 9, ensuring that the drive rod 9 can smoothly push the drive disk 5 to move back and forth in the left and right directions and that the drive rod 9 can smoothly push the inner cover 3 to rotate back and forth through the drive disk 5.

[0033] In this embodiment, the outer surface of the outer cover 2 is provided with a plurality of air inlets 12. Air conditioning air enters the outer cover 2 through the air inlets 12 and is discharged from the inner hole of the inner cover 3 to cool or heat the interior space of the car.

[0034] In this embodiment, the synchronization device includes two hinge rods 13 that are hinged to each other between adjacent wind deflectors 4. The outer end of each hinge rod 13 is hinged to the corresponding wind deflector 4. When one of the wind deflectors 4 rotates, the other wind deflectors 4 are driven to rotate synchronously through the hinge rod 13.

[0035] In this embodiment, a vertical rod 14 is hinged to the front side of the drive disk 5, and the vertical rod 14 is fixedly set with the corresponding wind deflector 4; thus achieving the purpose of hinged connection between the drive disk 5 and the wind deflector 4.

[0036] In this embodiment, each wind deflector 4 is provided with a relief groove 15 at the position corresponding to the hinge rod 13. When the wind deflector 4 rotates, the hinge rod 13 rotates in the relief groove 15 without interfering with the rotation of the wind deflector 4.

[0037] In this embodiment, each wind deflector 4 is fixedly provided with a vertical shaft 16 along the vertical direction. The vertical shaft 16 is rotatably connected to the inner cover 3 to achieve the purpose of rotatably connecting the wind deflector 4 and the inner cover 3.

[0038] In this embodiment, a fixing plate 17 is fixedly installed on the outer surface of the outer cover 2, and the motor 7 is fixedly installed with the fixing plate 17 to achieve the purpose of fixing the motor 7 with the outer cover 2.

[0039] The working principle of this utility model is as follows: During use, the motor 7 drives the radial rod 8 to rotate, and the radial rod 8 drives the drive rod 9 to revolve around the output shaft of the motor 7. This causes the drive rod 9 to drive the drive disc 5 to reciprocate in the left and right directions via the drive groove 6, causing the wind deflector 4 to rotate reciprocally, thereby achieving the purpose of reciprocating the wind direction in the left and right directions. The motor 7 drives the drive rod 9 to rotate via the radial rod 8. When the drive rod 9 is located below the hinge shaft 10, the outer end of the radial rod 8 extends to the right and forward, causing the drive rod 9 to push the inner cover 3 to rotate via the drive disc 5, thus changing the wind direction of the inner cover. The outer side of the inner hole of body 3 is inclined upward; when the drive rod 9 is above the hinge shaft 10, for the same reason, the drive rod 9 pushes the inner cover body 3 to rotate in the opposite direction through the drive disc 5, so that the outer side of the inner hole of the inner cover body 3 is inclined downward; thereby realizing the purpose of the air vent swinging back and forth in the up and down direction; when used in conjunction with the baffle plate 4, the air vent swings back and forth in the left and right direction and back and forth in the up and down direction, so as to realize the purpose of scanning the air inside the car; a button is provided on the instrument panel 1 to control the start and stop of the motor 7. When the motor 7 stops, the air vent blows air in a directional direction.
