Limiting structure of tuyere blade

Abstract

According to the tuyere blade limiting structure provided by the utility model, when the blade needs to blow air, the shifting button is shifted upwards, the shifting button and the shifting button bracket are rotated by 25 degrees, and the blade is driven to rotate by 25 degrees by taking the metal shaft as the axis, at the moment, the blade drives the connecting rod to move upwards, and the blade cannot continue to rotate after rotating by 25 degrees due to the limitation of the hole position of the second blade bracket; the blades are limited to continuously rotate, so that upward blowing of the blades is realized; when the blades need to blow downwards, the poking button is poked downwards, the poking button and the poking button support are rotated by 19 degrees, the blades are driven to rotate by 19 degrees with the metal shaft as the axis, at the moment, the blades drive the connecting rod to move downwards, due to the fact that the position of the second blade support is limited, the blades cannot continue to rotate after rotating by 19 degrees, continuous rotation of the blades is limited, and therefore downward blowing of the blades is achieved. When external force is applied (namely, the shifting button is shifted), the blades can rotate, and the damping function is to improve the operation feeling and increase the resistance of the blades.

Description

Technical Field

[0001] The utility model belongs to the technical field of automobile air outlets, and in particular relates to an air outlet blade limiting structure. Background Art

[0002] The air outlet of the car air conditioner guides the air flow by flipping the blades so that it can blow to different parts of the driver and passenger's body and improve the driving experience. The flip angle of the blades is limited to a range. Usually, the limit shaft at the end of the blade rotates to a limited angle and collides with the groove on the side wall of the air outlet to achieve the limit.

[0003] However, there are few single-blade limit structures for tuyere in the market. This structure uses a connecting rod structure to adjust the blowing angle of the tuyere blades. The connecting rod of the tuyere is designed to be below the blade, and the operating force of the connecting rod is easy to control and takes up less space. Utility Model Content

[0004] The utility model provides a tuyere blade limiting structure, aiming to solve the problems raised by the background technology.

[0005] The utility model is implemented as follows: a tuyere blade limiting structure comprises a shell and a blade;

[0006] A first blade bracket and a second blade bracket are respectively provided on both sides of the shell, and the first blade bracket and the second blade bracket are each connected to a metal shaft, and the blade is provided between the two metal shafts, and the blade is rotatably connected to the metal shaft. A connecting rod is provided on the inner side of the second blade bracket, one end of the connecting rod is connected to the blade, and the other end is connected to the second blade bracket, and a damper is provided at the connection between the connecting rod and the second blade bracket.

[0007] Preferably, the connecting rod is an L-shaped structure, the connecting rod is rotatably connected to the blade, and the connecting rod is rotatably connected to the second blade bracket.

[0008] Preferably, a button bracket is provided on the outer wall of the blade.

[0009] Preferably, a dial button is fixedly provided on the dial button bracket.

[0010] Preferably, the housing is arranged on a central control instrument panel of a car.

[0011] Preferably, the shell is connected to the air duct of the automobile air conditioner.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The blades ensure the rotation angle of the blades through the connecting rod and the first blade bracket and the second blade bracket structure; when the blades need to blow air upward, the dial button is pushed upward, the dial button and the dial button bracket rotate 25°, and drive the blades to rotate 25° with the metal shaft as the axis. At this time, the blades drive the connecting rod to move upward. Due to the position limitation of the opening of the second blade bracket, the blades cannot continue to rotate after 25° of rotation, and the blades are restricted from continuing to rotate, thereby achieving the blades blowing air upward; when the blades need to blow air downward, the dial button is pushed downward, the dial button and the dial button bracket rotate 19°, and drive the blades to rotate 19° with the metal shaft as the axis. At this time, the blades drive the connecting rod to move downward. Due to the position limitation of the opening of the second blade bracket, the blades cannot continue to rotate after 19° of rotation, and the blades are restricted from continuing to rotate, thereby achieving the blades blowing air downward; when external force is applied (i.e., the dial button is pushed), the blades can rotate, and the role of damping is to enhance the operating feel and increase the resistance of the blades.
