Background Art

[0002] Existing air-conditioning vents are usually equipped with rotatable horizontal blades to adjust the air outlet direction up and down. In the process of realizing the present invention, the inventors found that there are at least the following problems in the prior art: for example, the horizontal blades of existing automobile air-conditioning vents are mostly external and fixedly installed with a dial button for adjusting the air direction. The external blades, dial button and air vent panel require high-strength materials, resulting in abnormally high costs; the structure and appearance of the air-conditioning vent are complicated and cannot meet the requirements of the simple styling of the dashboard.

[0003] Those skilled in the art have conducted research and development to address the above-mentioned technical issues, and have specifically disclosed a hidden air outlet structure. However, the air outlet structure of this technical solution is complex. This technical solution requires that the shell be provided with a bending portion to achieve the hidden setting of the air-conditioning outlet parts, and the air intake volume control requires the addition of control blades. The structure is complicated and the cost is high, and the wind is consumed when passing through the lengthy air guide channel, resulting in low air outlet efficiency. Summary of the Invention

[0007] Furthermore, the front end surface of the rotating air guide portion and the rear end surface of the fixed air guide portion are two curved surfaces with complementary shapes, and the two curved surfaces are arranged to be separated by a preset width.

[0008] Furthermore, the front end of the fixed air guide part is contracted and forms two air guide channels with the upper shell and the lower shell respectively, extending obliquely and intersecting in front of the air outlet of the air conditioner. The rear end of the fixed air guide part is set as a concave curved surface, and the rotating air guide part is set as a gourd-like structure with protruding arcs at both ends. The small arc end can be inwardly cut at the rear end of the lower fixed air guide part.

[0009] Furthermore, a connector is fixedly installed on the rotating air guide portion, and the connector is engaged with a driving gear of the control motor.

[0010] Furthermore, a driven gear meshing with the corresponding driving gear is installed on the side wall of the connector, and the connector is provided with embedded bolts and an elastic buffer device is installed inside to offset the excess stroke of the control motor.

[0027] Existing air conditioning outlet (such as Figure 1 ) is usually provided with a rotatable horizontal blade to adjust the air outlet direction up and down. The horizontal blade is protruding and partially exposed on the outside of the shell. For example, the existing automobile air-conditioning outlet structure has horizontal blades extending out of the shell and a dial button for adjusting the wind direction is fixed on the outside of the blade. The external blades and the dial button have high requirements on material strength and hardness. More importantly, the protruding blades and the dial button have the risk of collision due to sudden stop of the car, which is not conducive to safe driving; the appearance of the air-conditioning outlet structure is complicated and it is difficult to meet the needs of simple styling of the dashboard.

[0028] Technical personnel in this field have conducted research and development to address the above technical issues and developed an air-conditioning outlet structure. This technical solution requires that the shell be provided with a bending portion to achieve the hidden setting of the air-conditioning outlet parts, and requires the addition of control blades inside to regulate the air intake volume. The structure is redundant and the cost is high.

[0029] The technical solution of the present invention provides a hidden air-conditioning outlet, an air-conditioning device with the hidden air-conditioning outlet, a motor vehicle with the air-conditioning device, and an air-guiding method based on the hidden air-conditioning outlet. There is no need to add control blades in the air-guiding channel to regulate the airflow. The air outlet angle and the air volume at a specific angle can be adjusted by rotating the air-guiding part.

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0031] Example 1:

[0032] The embodiment of the present invention discloses a hidden air-conditioning outlet structure. Different from the existing air-conditioning outlet, its blades are arranged inside the shell, and the air outlet angle and air volume can be controlled without adding a control valve inside. The specific structure of the hidden air-conditioning outlet is as follows: Figure 2 As shown, it at least includes a shell 1, a fixed air guide part 2, a rotating air guide part 3 and a control motor 4 for driving the rotating air guide part, wherein: the shell 1 has an inner cavity and is provided with openings at both ends, the shell 1 is retracted at the front end and the fixed air guide part 2 and the rotating air guide part 3 are arranged in the inner cavity, the shell is divided into an upper shell and a lower shell, the fixed air guide part 2 and the rotating air guide part 3 respectively form an upper air guide channel and a lower air guide channel with the upper shell and the lower shell; the fixed air guide part 2 is installed at the front end of the shell 1 and the rotating air guide part 3 is arranged behind the fixed air guide part 2, the front end of the rotating air guide part 3 can be inscribed and rotatably arranged at the rear end of the fixed air guide part 2, and the control motor The rear end of the air guide portion 3 is driven to rotate up and down to control the opening of the upper and lower air guide channels, thereby adjusting the air outlet angle. On the one hand, this solution can overcome the problem that the existing air outlet needs to manually adjust the up and down wind direction and has low adjustment accuracy and poor user experience, and can accurately and intelligently adjust the wind direction. On the other hand, the air flowing through the upper and lower air supply channels intersects at the air outlet and causes a deflection in the wind direction, thereby forming a fan-shaped air outlet area. Since the air is continuously supplied in this fan-shaped area, when the blades are controlled to move, the instantaneous change in wind direction is subtle and gradual, and the user is not likely to feel the sudden change in wind direction and the change in body surface temperature.

[0033] In this embodiment, the rotating air guide portion and the fixed air guide portion are separated by a preset distance. To further rationalize the structure, the front end surface of the rotating air guide portion and the rear end surface of the fixed air guide portion are two curved surfaces with complementary shapes, and the two curved surfaces are separated. Figure 3 As shown, the rear end of the fixed air guide 2 is set as a concave curved surface, the front end of the rotating air guide 3 is a protruding curved surface that complements the shape of the concave curved surface, and the front end of the rotating air guide 3 rotates on the inner side of the concave curved surface without contact. In other embodiments, the rear end of the fixed air guide is set as a protruding curved surface, the front end of the rotating air guide is a concave curved surface that complements the shape of the protruding curved surface, the concave curved surface is sleeved outside the protruding curved surface, and the rotating air guide rotates on the outer side of the protruding curved surface without contact. Figure 4 As shown, the fixed air guide portion 2 is divided into an upper fixed air guide blade and a lower fixed air guide blade that is snap-connected to the rear of the upper fixed air guide blade. The front end of the upper fixed air guide blade is retracted and forms an air guide channel that extends obliquely with the upper and lower shells and intersects in front of the air conditioner outlet. The rotating air guide portion 3 is divided into a lower rotating air guide blade and an upper rotating air guide blade correspondingly mounted above the lower rotating air guide blade. The upper and lower rotating air guide blades form a gourd-like structure with arcs at both ends, wherein the small arc end is matched and arranged at the rear end of the lower fixed air guide blade, and the large arc end rotates up and down to adjust the opening of the air guide channel and control the opening and closing of the air guide channel. To further reduce system operating noise and reduce costs, the fixed air guide portion and the rotating air guide portion can be made of soft materials. Since they are hidden inside the air conditioner outlet, even if soft materials are used, they can still meet the strength requirements.

[0034] like Figure 4 As shown, the rotating air guide 3 is fixedly mounted with a connector 5, which meshes with the driving gear of the control motor 4. A driven gear corresponding to the driving gear is mounted on the sidewall of the connector 5. The driven gear, which meshes with the corresponding driving gear, cooperates with the gear of the control motor through the connector, enabling the control motor to clutch the rotating air guide, thereby precisely controlling the rotation angle. The connector 5 is provided with embedded bolts 51 and an elastic buffer device is installed inside the connector 5. In this embodiment, the elastic buffer device is a spring, which is arranged outside the embedded bolts 51 to offset the motor's excess travel and extend the motor's service life. In this embodiment, the control motor 4 is controlled by a stepper motor, which has a high speed selectivity, flexible installation conditions, and is conducive to precise position control and reduced noise.

[0035] like Figure 4 As shown, a laterally extending decorative baffle 6 is fixedly installed at the front end of the air outlet of the air conditioner corresponding to the air outlet position of the two air guide channels, and the baffle 6 is arranged at the front end of the fixed air guide part 2 with a preset gap. The baffle can guide the airflow to blow outward, and the functional gap set between it and the fixed air guide part 2 is used for the airflow flowing through the upper and lower air guide channels to intersect at the front end of the air outlet of the air conditioner to form a directional outlet airflow.

[0036] To further rationalize the structure, Figure 4 In this embodiment, the upper shell and the lower shell are fixed as a whole by snapping. The upper and lower shells are provided with grooves at the sides and the middle respectively, which are sunken a preset distance for the air guide channel. The shells are fixedly connected to the fixed air guide part arranged inside the shells through the grooves to improve the stability of the system operation.

[0037] Example 2:

[0038] In the embodiment of the present invention, the front end face of the rotating air guide part is a two curved surfaces with complementary shapes to the rear end face of the fixed air guide part. A damping material layer is coated between the two curved surfaces to reduce the system operation noise. The two curved surfaces are connected and form two unconnected and closed air guide channels on the upper and lower sides of the shell, which is conducive to independent and stable air guidance of the two air guide channels.

[0039] Example 3:

[0040] The embodiment of the present invention, based on the embodiment 1, discloses an air-conditioning device, which has an air-conditioning outlet and also includes a central processing unit for sending an operating instruction to a control motor.

[0041] Example 4:

[0042] Based on Example 3, the embodiment of the present invention discloses a motor vehicle having an air-conditioning device installed inside a vehicle console, and the vehicle console is connected to the air-conditioning outlet and extends outward from the outlet.

[0043] Example 5:

[0044] An embodiment of the present invention discloses an air guiding method based on the air-conditioning outlet structure, comprising the following steps: when the air-conditioning outlet needs to guide air upward or downward, the control motor receives a control signal, drives the front end of the rotating air guide part to be rotatably arranged inwardly at the rear end of the fixed air guide part, and further pulls the rear end of the rotating air guide part to rotate upward or downward, so as to control the opening and closing of the upper and lower air guide channels and the air flow rate, thereby adjusting the air outlet direction.

[0045] Specifically, when the rotating wind shield is in the horizontal position, the air flows from the upper and lower air guide channels to the air outlet of the air conditioner with the same air volume, and is guided by the front housing 1 respectively, and intersects at the front end of the air outlet of the air conditioner and is discharged in a horizontal direction (see Figure 5 ); When the rear end of the rotating air guide portion 3 rotates downward from the horizontal position, the opening of the upper air guide channel increases and the opening of the lower air guide channel decreases, and the air outlet direction of the air conditioner gradually deflects downward until the rotating air guide portion 3 moves downward to fit the inner surface of the shell 1 (see Figure 6), the lower air guide channel is completely closed, all air flows from the upper air guide channel to the air outlet of the air conditioner, and is guided by the front shell 1 to discharge air downward; when the rear end of the rotating air guide part 3 rotates upward from the horizontal position, the opening of the upper air guide channel is reduced and the opening of the lower air guide channel is increased, and the air outlet direction of the air conditioner gradually deflects upward. When the rotating air guide part 3 moves upward to fit the inner surface of the shell 1 (see Figure 7 ), the upper air guide channel is completely closed, and all air flows from the lower air guide channel to the air outlet of the air conditioner and is guided upward by the front shell 1.

[0046] The above is a detailed introduction to a hidden air-conditioning outlet, air-conditioning equipment, motor vehicle and air-guiding method. Specific examples are used herein to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the core idea of ​​the present invention. At the same time, for those skilled in the art, according to the ideas and methods of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present invention.
