Note that the relative arrangement, numerical expressions and numerical values of the components and steps set forth in these embodiments are not limiting to the scope of the present application unless otherwise specifically stated.

[0031] Techniques, methods, and apparatus known to those of ordinary skill in the relevant art can not be discussed in detail herein. However, where appropriate, such techniques, methods, and apparatus should be considered as part of the description of the application.

[0032] In all of the examples shown and discussed herein, any specific values should be interpreted as merely illustrative and not as a limitation. Thus, other examples of the exemplary embodiments can have different values.

[0033] As Figures 1 to 4 shown, the structure of the air outlet of the automobile air conditioner is provided with an air outlet frame 1, a front row of blades 2, an auxiliary air guide assembly 3 and a connecting rod assembly 4.

[0034] The air outlet frame 1 includes an air outlet 11. Specifically, the auxiliary air guide assembly 3 and the connecting rod assembly 4 are both arranged in the air outlet frame 1, the two ends of the air outlet frame 1 are respectively an air inlet (not shown in the figure) and the air outlet 11, and the front row of blades 2, the auxiliary air guide assembly 3 and the connecting rod assembly 4 are all located on one end of the air outlet 11.

[0035] The front row of blades 2 is located at the air outlet 11 and is rotationally connected to the air outlet frame 1. Specifically, the front row of blades 2 is at least partially arranged in the air outlet 11, and by rotating the front row of blades 2 up and down, the air flow directed from the air outlet 11 is blown up and down.

[0036] The auxiliary air guide assembly 3 comprises an upper air guide blade 31 and a lower air guide blade 32, the upper air guide blade 31 and the lower air guide blade 32 are arranged above and below the front row of blades 2 respectively, and the upper air guide blade 31 and the lower air guide blade 32 are arranged in the air outlet frame 1. It should be noted that the upper air guide blade 31 and the lower air guide blade 32 can be a straight plate structure, can be a bent plate structure, or the upper air guide blade 31 or the lower air guide blade 32 can be a straight plate structure, and the lower air guide blade 32 or the upper air guide blade 31 can be a bent plate structure, which is not limited here.

[0037] The two ends of the connecting rod assembly 4 are connected with the upper air guide blade 31 and the lower air guide blade 32 respectively, and the connecting rod assembly 4 has a bending part between the two ends, and the bending part is connected with the front row of blades 2. Specifically, the upper air guide blade 31 and the lower air guide blade 32 are connected with the front row of blades 2 through the connecting rod assembly 4, and the upper air guide blade 31 and the lower air guide blade 32 are rotated up and down with the front row of blades 2. When the front row of blades 2 rotates downward, the upper air guide blade 31 and the lower air guide blade 32 rotate downward. When the front row of blades 2 rotates upward, the upper air guide blade 31 and the lower air guide blade 32 rotate upward.

[0038] The present application arranges the upper air guide blade 31 and the lower air guide blade 32 above and below the front row of blades 2 respectively, and the upper air guide blade 31 and the lower air guide blade 32 are arranged in the air outlet frame 1, so that the two ends of the connecting rod assembly 4 are connected with the upper air guide blade 31 and the lower air guide blade 32 respectively, and the bending part between the two ends of the connecting rod assembly 4 is connected with the front row of blades 2. When the front row of blades 2 works, the front row of blades 2 rotates up and down at the air outlet 11, and the upper air guide blade 31 and the lower air guide blade 32 are rotated up and down with the front row of blades 2 through the connecting rod assembly 4, thereby solving the problem that the air flow is difficult to blow over the head when the face blowing air outlet 11 is located at the lower position, optimizing the blowing path of the face blowing air outlet 11, and improving the blowing performance of the face blowing air outlet 11.

[0039] In one embodiment of the air outlet structure of the automobile air conditioner face blowing air outlet of the present application, as shown in Figures 1 to 4 The angle formed by the upper air guide blade 31 and the lower air guide blade 32 and the inner side end of the front row of blades 2 is an acute angle in the moving state of the upper air guide blade 31, the front row of blades 2 and the lower air guide blade 32. Specifically, the outer side end of the front row of blades 2 is located outside the air outlet frame 1, and the inner side end of the front row of blades 2 is located inside the air outlet frame 1. The upper air guide blade 31 and the lower air guide blade 32 are both arranged obliquely, and the angle formed with the inner side end of the front row of blades 2 is an acute angle.

[0040] This invention optimizes the airflow path of the surface air outlet 11 and improves its airflow performance by setting the angle between the upper guide vane 31, the lower guide vane 32 and the inner end of the front row vane 2 when the upper guide vane 31, the lower guide vane 32 and the inner end of the front row vane 2 are set to an acute angle while the upper guide vane 31, the front row vane 2 and the lower guide vane 32 are in a moving state.

[0041] In this embodiment, the lower guide vane 32 is bent. Specifically, the lower guide vane 32 includes a first guide plate and a second guide plate. The side wall of the first guide plate is rotatably connected to the inner wall of the air outlet frame 1. The first end of the first guide plate is connected to the first end of the second guide plate, and the angle formed between the first end of the second guide plate and the first end of the first guide plate is an obtuse angle. The second guide plate is inclined toward the front row of blades 2. This arrangement further optimizes the airflow path of the air outlet 11, allowing the airflow to be guided by the second guide plate and blow over the driver's head, thus meeting the user's needs.

[0042] In one embodiment of the automotive air conditioning blower vent structure of the present invention, such as Figures 1 to 4 As shown, the first end of the upper guide vane 31 is rotatably connected to the top of the air outlet frame 1, and the second end of the upper guide vane 31 is connected to the first end of the connecting rod assembly 4.

[0043] The first end of the lower guide vane 32 is rotatably connected to the bottom end of the air outlet frame 1, and the second end of the lower guide vane 32 is connected to the second end of the connecting rod assembly 4.

[0044] This invention achieves stability in the movement of the upper and lower guide vanes 31 by rotatably connecting the first end of the upper guide vane 31 to the top of the air outlet frame 1, connecting the second end of the upper guide vane 31 to the first end of the connecting rod assembly 4, rotatably connecting the first end of the lower guide vane 32 to the bottom of the air outlet frame 1, and connecting the second end of the lower guide vane 32 to the second end of the connecting rod assembly 4.

[0045] In one embodiment of the automotive air conditioning blower vent structure of the present invention, such as Figures 2 to 4 As shown, a first connecting shaft 311 is provided on the first end of the upper air guide blade 31, and a second connecting shaft 321 is provided on the first end of the lower air guide blade 32. A first mounting hole (not shown in the figure) and a second mounting hole (not shown in the figure) are provided on the top and bottom ends of the side wall of the air outlet frame 1, respectively. The first connecting shaft 311 and the second connecting shaft 321 are rotatably connected to the first mounting hole and the second mounting hole, respectively.

[0046] Specifically, the first connecting shaft 311 and the second connecting shaft 321 are respectively disposed on the side wall of the first end of the upper guide vane 31 and the side wall of the first end of the lower guide vane 32, and the first connecting shaft 311 and the second connecting shaft 321 have the same length. The diameter of the first mounting hole and the diameter of the second mounting hole are respectively matched with the diameter of the first connecting shaft 311 and the diameter of the second connecting shaft 321.

[0047] The present invention provides a first connecting shaft 311 and a second connecting shaft 321 on the upper guide vane 31 and the lower guide vane 32, respectively, and provides a first mounting hole and a second mounting hole on the top and bottom of the side wall of the air outlet frame 1, respectively, so that the first connecting shaft 311 and the second connecting shaft 321 are rotatably connected to the first mounting hole and the second mounting hole, respectively, thereby further ensuring the stability of the connection between the upper guide vane 31 and the lower guide vane 32 and the air outlet frame 1, and improving the service life of the automotive air conditioning blowing air outlet structure.

[0048] In one embodiment of the automotive air conditioning blower vent structure of the present invention, such as Figures 2 to 4 As shown, the upper guide vane 31 and the lower guide vane 32 have corresponding first notches 312 and second notches 322 on the same side, and the two ends of the connecting rod assembly 4 are located at the first notches 312 and the second notches 322. Specifically, the first notches 312 and the second notches 322 have a certain length so that the connecting rod assembly 4 does not collide with the upper guide vane 31 and the lower guide vane 32 when rotating. Furthermore, the first connecting shaft 311 and the second connecting shaft 321 are respectively located on the first notches 312 and the second notches 322.

[0049] The present invention provides a first notch 312 and a second notch 322 on the same side of the upper guide vane 31 and the lower guide vane 32, so that the two ends of the connecting rod assembly 4 are set on the first notch 312 and the second notch 322, thereby preventing the connecting rod assembly 4 from colliding with the upper guide vane 31 and the lower guide vane 32 when rotating, thus ensuring the smoothness of the rotation of the connecting rod assembly 4.

[0050] In one embodiment of the automotive air conditioning blower vent structure of the present invention, such as Figures 2 to 4 As shown, the linkage assembly 4 includes a first linkage 41 and a second linkage 42. The first end of the first linkage 41 is connected to the upper guide vane 31, the second end of the first linkage 41 is connected to the first end of the second linkage 42, the second end of the second linkage 42 is connected to the lower guide vane 32, the angle between the first linkage 41 and the second linkage 42 is an acute angle, and the connection between the first linkage 41 and the second linkage 42 is connected to the front row vane 2.

[0051] Specifically, since the first end of the upper guide vane 31 and the first end of the lower guide vane 32 are respectively used for the rotatable connection of the air outlet 11 frame, and the first end of the first connecting rod 41 is connected to the second end of the upper guide vane 31, and the second end of the second connecting rod 42 is connected to the second end of the lower guide vane 32, when the front row of blades 2 rotates, the second ends of the upper guide vane 31 and the second ends of the lower guide vane 32 rotate up and down with the front row of blades 2 through the first connecting rod 41 and the second connecting rod 42, thereby ensuring that most of the airflow in the air outlet 11 frame rotates up and down with the upper guide vane 31, the lower guide vane 32 and the front row of blades 2, and the air blows up and down, increasing the airflow of the air blower, improving the blowing performance of the air outlet 11, optimizing the blowing path of the air outlet 11, and meeting the needs of users.

[0052] Furthermore, the length of the first link 41 is less than the length of the second link 42. Since the lengths of the first link 41 and the second link 42 are different, and the length of the first link 41 is less than the length of the second link 42, when the first link 41 moves to the highest or lowest position, and when the upper guide vane 31 moves to both ends of the first link 41, the lower guide vane 32 has not yet moved to the end of the second link 42, thus creating a free stroke between the lower guide vane 32 and the second link 42. This allows for different rotation angles between the upper guide vane 31, the lower guide vane 32, and the front row vanes 2, thereby solving the problem of arranging the upper guide vane 31, the lower guide vane 32, and the front row vanes 2 even when there is insufficient space within the air outlet 11 frame, increasing the flexibility of the automotive air conditioning blow-out structure of this invention.

[0053] In one embodiment of the automotive air conditioning blower vent structure of the present invention, such as Figures 2 to 4 As shown, the front blade 2 is provided with a groove 21 and a connecting post 22, with the connecting post 22 disposed inside the groove 21; a third connecting hole 43 is provided at the connection between the first connecting rod 41 and the second connecting rod 42, and the connecting post 22 is rotatably connected to the third connecting hole 43. Specifically, the groove 21 is provided correspondingly to the first connecting shaft 311 and the second connecting shaft 321, and the groove 21 is located at one end near the front blade 2.

[0054] The present invention provides a groove 21 and a connecting post 22 on the front blade 2, with the connecting post 22 placed inside the groove 21, and a third connecting hole 43 provided at the connection between the first connecting rod 41 and the second connecting rod 42, so that the connecting post 22 is rotatably connected to the third connecting hole 43, thereby ensuring the stability of the connection between the first connecting rod 41 and the second connecting rod 42 and the front blade 2.

[0055] In one embodiment of the automotive air conditioning blower vent structure of the present invention, such as Figures 2 to 4As shown, a first pin 313 is provided on the second end of the upper guide vane 31, and a second pin 323 is provided on the second end of the lower guide vane 32; a first connecting hole 44 is provided on the first end of the first connecting rod 41, and a second connecting hole 45 is provided on the second end of the second connecting rod 42; the first pin 313 and the second pin 323 are respectively inserted into the first connecting hole 44 and the second connecting hole 45.

[0056] The present invention provides a first pin 313 and a second pin 323 at the second end of the upper guide vane 31 and the second end of the lower guide vane 32, respectively, and provides a first connecting hole 44 and a second connecting hole 45 at the first end of the first connecting rod 41 and the second end of the second connecting rod 42, respectively, so that the first pin 313 and the second pin 323 are inserted into the first connecting hole 44 and the second connecting hole 45, thereby increasing the stability of the connection between the upper guide vane 31 and the lower guide vane 32 and the first connecting rod 41 and the second connecting rod 42.

[0057] In one embodiment of the automotive air conditioning blower vent structure of the present invention, the second connecting hole 45 is an oblong hole, the first connecting hole 44 is a circular hole, the first pin 313 is rotatably connected to the first connecting hole 44, and the second pin 323 is movably connected to the second connecting hole 45.

[0058] In this embodiment, since the second connecting hole 45 is an oblong hole and the first connecting hole 44 is a circular hole, when the first connecting rod 41 and the second connecting rod 42 drive the upper guide vane 31 and the lower guide vane 32 to rotate with the front row of vanes 2, the upper guide vane 31 is rotatably connected to the first connecting hole 44 through the first pin 313, so that the vertical displacement of the upper guide vane 31 is consistent with the vertical displacement of the front row of vanes 2. The lower guide vane 32 is movably connected to the second connecting hole 45 through the second pin 323, so that the vertical displacement of the lower guide vane 32 is different from the vertical displacement of the front row of vanes 2, that is, the rotation angle of the lower guide vane 32 is smaller than the rotation angle of the upper guide vane 31, thus changing the blowing path of the lower guide vane 32.

[0059] The present invention sets the second connecting hole 45 as an oblong hole and the first connecting hole 44 as a circular hole, so that the first pin 313 is movably connected to the first connecting hole 44 and the second pin 323 is rotatably connected to the second connecting hole 45. This makes the rotation angle of the lower guide vane 32 smaller than that of the upper guide vane 31, thus further solving the problem that the airflow is difficult to blow over the head because the air outlet 11 is located too low.

[0060] In one embodiment of the automotive air conditioning blower vent structure of the present invention, such as Figures 2 to 4As shown, the air outlet structure of the car air conditioner also includes a balancing component 5, which is used to stabilize the rotation of the front blades 2. The first end of the balancing component 5 is rotatably connected to the front blades 2, and the second end of the balancing component 5 is connected to the air outlet frame 1.

[0061] The balancing assembly 5 includes a connecting plate 51, on which a first rotating hole 52 and a second rotating hole 53 are provided; a first plug-in corresponding to the first rotating hole 52 is provided on the first end of the front row blades 2, and a second plug-in (not shown in the figure) corresponding to the second rotating hole 53 is provided on the air outlet frame 1; the first plug-in and the second plug-in are rotatably connected to the first rotating hole 52 and the second rotating hole 53, respectively.

[0062] Specifically, the first rotating hole 52 is a circular hole, and the second rotating hole 53 is an oblong hole. When the front row blades 2 are placed horizontally, the connecting plate 51, the second connector, and the front row blades 2 are in the same plane and are all placed horizontally.

[0063] The present invention provides a first rotating hole 52 and a second rotating hole 53 on the connecting plate 51, and provides a first plug-in corresponding to the first rotating hole 52 on the first end of the front blade 2, and provides a second plug-in corresponding to the second rotating hole 53 on the air outlet frame 1, so that the first plug-in and the second plug-in are rotatably connected to the first rotating hole 52 and the second rotating hole 53 respectively, thereby ensuring the stability of the front blade 2 during rotation.

[0064] While specific embodiments of the invention have been described in detail by way of examples, those skilled in the art should understand that the examples are for illustrative purposes only and not intended to limit the scope of the invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the invention.
