Description

Technical Field

[0001] The invention relates to the technical field of automobile accessories, and in particular to an automatically switched windless air outlet. Background Art

[0002] The car air-conditioning vent is one of the essential parts of a car. In order to meet the temperature requirements of drivers of different heights, body shapes and habits, the air-conditioning vent rotates along the rotation center to obtain the usual wind speed and temperature.

[0003] Currently, the air outlets on the market will blow out a large amount of air in a certain direction when the vehicle air conditioner is turned on. When the temperature inside the vehicle drops, the air outlet is still concentrated in one direction, which will make the passengers feel cold and greatly affect the passenger comfort, especially for the elderly and children, and easily cause colds and other problems.

[0004] Therefore, windless air outlets have appeared on the market. However, the current structure of windless air outlets is mostly a structure with uniform mesh holes arranged at the air outlet, which reduces the wind speed and evenly distributes the flow, but passengers will still feel the wind, which will cause discomfort to passengers for a long time.

A guide slope 1.4 is formed on the housing 1, and the guide slope 1.4 is arranged toward the outlet away from the air outlet channel 1.1. The second airflow is blown out from the auxiliary channel 1.2 and guided by the guide slope 1.4 to be blown away from the passengers; when the air outlet is installed in the car, the first airflow is blown out through the outlet of the air outlet channel 1.1 and blows towards the passenger position, and the second airflow is blown out through the outlet of the auxiliary channel 1.2 and blows away from the passenger position.

[0027] The shell 1 is also provided with a switching mechanism located in the air outlet channel 1.1, and the switching mechanism includes a wind shield 2 rotatably installed in the air outlet channel 1.1 and in a normally closed state, and a pre-tightening mechanism 3 that provides a pre-tightening force for the wind shield 2. The side wall of the wind shield 2 extends to form a rotating shaft, and the wind shield 2 is rotatably installed on the shell 1 via the rotating shaft.

[0028] When the thrust of the airflow entering the air outlet channel 1.1 is greater than the preload force, the airflow pushes open the wind shield 2, and the airflow is blown out from the outlets of the auxiliary channel 1.2 and the air outlet channel 1.1 at the same time; when the thrust of the airflow entering the air outlet channel 1.1 is less than the preload force, the wind shield 2 closes the air outlet channel 1.1, and the airflow is blown out only from the outlet of the auxiliary channel 1.2.

[0029] Specifically, the preload assembly includes an elastic member 3.1 acting on the wind shield 2 and an adjusting member 3.2 cooperating with the elastic member 3.1. The elastic member 3.1 provides a preload force for the damper by deforming, and the adjusting member 3.2 adjusts the preload force of the elastic member 3.1 acting on the wind shield 2 by adjusting the degree of deformation of the elastic member 3.1.

[0030] The pre-tightening assembly also includes a damper gear 3.3, a gear set 3.4, a mounting gear 3.5, and a mounting seat 3.6. The damper gear 3.3 is connected to the end of the wind shield 2. The mounting gear 3.5 is connected to the damper gear 3.3 through the gear set 3.4. When the mounting gear 3.5 rotates, the damper gear 3.3 is driven to rotate through the gear set 3.4, thereby causing the wind shield 2 to rotate.

[0031] The mounting seat 3.6 is fixedly connected to the mounting gear 3.5, and a mounting cavity is formed in the mounting seat 3.6. In this embodiment, the elastic member 3.1 is a disc-shaped energy storage spring, which is arranged in the mounting cavity, and the head end of the adjusting member 3.2 extends into the mounting cavity, and the head end member of the adjustment is located at the center of the energy storage spring, so that one end of the energy storage spring is connected to the adjusting member 3.2, and the other end of the energy storage spring is connected to the mounting seat 3.6. The adjusting member 3.2 is movably arranged, and the deformation degree of the energy storage spring can be adjusted by rotating the adjusting member 3.2. Through the deformation degree of the energy storage spring, the elastic force is transmitted to the wind shield 2 through the gear set 3.4 and the damper gear 3.3, so that the pre-tightening force provided to the wind shield 2 can be adjusted. The wind shield 2 needs to overcome the pre-tightening force to open. When the thrust of the airflow in the air outlet channel 1.1 acting on the damper is greater than the pre-tightening force of the elastic member 3.1, the airflow pushes the wind shield 2 open. The elastic member 3.1 can provide a pre-tightening force for the damper.

[0032] The housing 1 is provided with an operating rod 4, the end of the adjusting member 3.2 is provided with a transmission gear 3.7, the end of the operating rod 4 is provided with an output gear 3.8 extending into the housing 1 and meshing with the transmission gear 3.7, and the head end of the operating rod 4 is located outside the housing 1 for user operation. By rotating the operating rod 4, the adjusting member 3.2 can be driven to rotate, thereby adjusting the deformation degree of the elastic member 3.1, and then the force of the elastic member 3.1 can be adjusted.

[0033] In addition, the shell 1 also has a main air blade 5 and a secondary air guide blade 6 located in the air outlet channel 1.1 rotatably installed. The main air blade 5 is horizontally arranged in the shell 1. By rotating the main air blade 5, the up and down wind direction can be adjusted. The secondary air guide blade 6 is vertically arranged in the shell 1. By rotating the secondary air guide blade 6, the left and right wind direction can be adjusted.

[0034] The operating rod 4 is connected to the main air flow blade 5 through the main transmission assembly 7, and the operating rod 4 is connected to the secondary air guide blade 6 through the secondary transmission assembly 8, so as to adjust the wind direction of the first air flow flowing out of the air outlet channel 1.1. The operating rod 4 is installed on the housing 1 through the steering assembly, and the steering assembly includes an outer shell and an inner shell, the outer shell is fixedly installed in the housing 1, the inner shell is arranged in the outer shell, and the two sides of the outer shell are provided with a slide groove, and the two sides of the inner shell are provided with a rotating shaft that cooperates with the slide groove. Through the cooperation of the rotating shaft and the slide groove, the inner shell can swing up and down and left and right relative to the outer shell, so the operating rod 4 passes through the inner shell and is rotationally connected with the inner shell, and the end of the operating rod 4 is connected to the output gear 3.8 through a universal joint, when the operating rod 4 swings up and down, the main air flow blade 5 is driven to rotate up and down through the main transmission assembly 7, when the operating rod 4 swings left and right, the secondary air guide blade 6 is driven to rotate left and right through the secondary transmission assembly 8, and when the operating rod 4 rotates, the output gear 3.8 is driven to rotate. By arranging the steering assembly, the operating rod 4 can swing up and down, swing left and right, and rotate.

[0035] In this embodiment, a slot is provided at the bottom of the inner shell, and an insertion rod extending into the slot is provided at the input end of the secondary transmission assembly 8. A shift fork cooperating with the main transmission assembly 7 is installed on the side wall of the inner shell. When the inner shell swings up and down, the shift fork cooperates with the main transmission assembly 7 to drive the secondary air guide blade 6 to swing, and the secondary transmission assembly 8 does not respond to the movement of the inner shell. When the inner shell swings left and right, the insertion rod cooperates with the slot transmission, so that the secondary air guide blade 6 can be driven to swing through the secondary transmission assembly 8, and the main transmission assembly 7 does not respond to the movement of the inner shell, and due to the presence of the universal joint, when the operating rod 4 swings up and down and left and right, the output gear 3.8 does not respond to its movement.

[0036] The air outlet mechanism of the present invention, by setting an air outlet channel 1.1 and an auxiliary channel 1.2, makes the outlet air outlet direction of the air outlet channel 1.1 blow toward the passengers, and the outlet air outlet direction of the auxiliary channel 1.2 is away from the passengers, and an air guide plate and a pre-tightening mechanism 3 are set in the air outlet channel 1.1. When air enters the air outlet channel 1.1, when the thrust of the airflow entering the air outlet channel 1.1 is greater than the pre-tightening force of the wind shield 2, the airflow pushes the wind shield 2 open, and at this time the airflow is blown out from the outlets of the auxiliary channel 1.2 and the air outlet channel 1.1 at the same time. The airflow blown out from the air outlet channel 1.1 can directly blow on the passengers, and can quickly cool down the interior of the vehicle. When the thrust of the airflow entering the air outlet channel 1.1 is less than the pre-tightening force of the wind shield 2, the wind shield 2 is in a closed state. At this time, the airflow is blown out only from the outlet of the auxiliary channel 1.2, and the air outlet direction is away from the passengers, so that the passengers cannot feel the wind, and the user experience effect is better.
