Description

Technical Field

[0001] This application relates to the field of automotive air conditioning technology, and in particular to an ultra-long single-blade air outlet structure for automotive air conditioning. Background Technology

[0002] Car interior air conditioning vents typically consist of front and rear air guide vanes. The front air guide vanes are a multi-blade design, with multiple vanes rotating simultaneously via a toggle lever to change the airflow angle. However, the multi-blade design of the front air guide vanes results in more parts, higher cost, and is impractical.

[0003] Among related technologies, a single-blade automotive air conditioning vent assembly is provided. It achieves air outlet by setting multiple sets of vertically distributed secondary blades inside the housing and setting a horizontal main blade outside the housing opening. Its structure is simple and reduces costs.

[0004] The single-blade type automotive air conditioning vent assembly adapts to the trend of hidden and simple interior design. The height of the vent is reduced from the conventional 50mm to 35mm, and the number of front air guide blades is reduced from 3-5 to 1. To ensure that the air outlet area of ​​a single vent remains unchanged, the width of this vent is widened to about 220mm.

[0005] However, with the increased width of the air outlet, the length of the horizontal main blade of the single-blade automotive air conditioning outlet assembly has increased significantly compared to the multi-blade type of front guide blade, making it difficult for the structural rigidity and strength of the horizontal main blade to meet the requirements.

[0006] When adjusting the airflow or direction of the air conditioner vent, it is inevitable that excessive force will be applied to the horizontal main blade (a force that is not in the same direction as the rotation of the horizontal main blade). This causes the middle of the horizontal main blade to be subjected to a vertical force and deform downwards. When the horizontal main blade is excessively deformed, it will break or the blade will fall off. Summary of the Invention

[0007] This application provides an ultra-long single-blade air outlet structure for automotive air conditioning to solve the problem in related technologies where the horizontal main blade deforms downward when subjected to a vertical force at the middle toggle point, and the horizontal main blade breaks or falls off after excessive deformation.

The windward surface of the horizontal wind guide blade is an arc surface, and the center of the arc surface is located on the rotation axis of the horizontal wind guide blade.

[0014] In some embodiments, the distance between the arc surface of the horizontal guide vane and the arc groove of the arc support is 0.1 to 1 mm, and the angle corresponding to the arc groove of the arc support is greater than the rotation angle of the horizontal guide vane.

[0017] The blade bearing housing is provided with an arc-shaped limiting groove at one end near the horizontal guide blade, and the two ends of the horizontal guide blade are also provided with limiting rods that extend into the arc-shaped limiting groove.

[0018] In some embodiments: the end of the horizontal guide vane near the blade bearing seat is fitted with the decorative strip to hide the metal shaft, and the center of the arc-shaped limiting groove is located on the rotation axis of the horizontal guide vane.

[0019] In some embodiments: the horizontal guide vane includes an outer guide vane, and the windward surface of the outer guide vane is provided with an elongated groove extending along the length direction of the outer guide vane.

[0020] The outer guide vane has a "∪" shaped cross-section, and a reinforcing skeleton is embedded in the elongated groove of the outer guide vane. The reinforcing skeleton is snapped together with the outer guide vane.

[0021] In some embodiments: the reinforcing frame has multiple positioning slots on the side away from the windward side, and the elongated slot of the outer guide vane has multiple positioning plates located in the positioning slots respectively;

[0022] The top and bottom surfaces of the reinforcing frame are provided with limiting ribs that interlock with the inner wall of the outer guide vane, and the bottom of the elongated groove is provided with multiple limiting protrusions that abut against the reinforcing frame.

[0042] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0043] This application provides an ultra-long single-blade air outlet structure for automotive air conditioning, which can solve the problem in related technologies where the horizontal main blade deforms downward when subjected to a vertical force at the middle toggle point, and the horizontal main blade breaks or falls off when it is excessively deformed.

[0044] See Figures 1 to 4 As shown in the figure, this application embodiment provides an ultra-long single-blade air outlet structure for automotive air conditioning, including:

[0045] An air conditioning vent includes an vent housing 1, which is mounted on the vehicle's dashboard. The vent housing 1 has an air outlet port 11 exposed on the dashboard. The air outlet port 11 of the vent housing 1 has a rotatable horizontal guide vane 2, which is used to adjust the airflow from the air outlet port 11 by moving it up and down. One horizontal guide vane 2 is provided to reduce the height of the air outlet port 11 of the vent housing 1. To maintain a constant airflow volume, the width of the air outlet port 11 is extended, resulting in a long and narrow structure. Correspondingly, the horizontal guide vane 2 located at the air outlet port 11 is also extended.

[0046] An arc-shaped support base 3 is connected to the air outlet port 11 of the air outlet housing 1. The arc-shaped support base 3 has an arc groove 31 on its windward side near the horizontal guide vane 2. The arc groove 31 is clearance-fitted with the horizontal guide vane 2, and the center of the arc groove 31 is located on the rotation axis of the horizontal guide vane 2. Because the air outlet port 11 forms a long and narrow structure, the length of the corresponding horizontal guide vane 2 is also extended. The extended horizontal guide vane 2 has reduced structural strength and is prone to bending and deformation under its own weight and external forces. In this embodiment, to prevent the extended horizontal guide vane 2 from bending and deforming during use, an arc-shaped support base 3 is provided at the air outlet port 11 of the air outlet housing 1 to support the horizontal guide vane 2.

[0047] To ensure sufficient rigidity and strength of the horizontal air guide blade 2 under vertical stress, the extra-long single-blade air outlet structure of this embodiment of the automotive air conditioning system incorporates an arc-shaped support 3 at the air outlet port 11 of the air outlet housing 1. When the horizontal air guide blade 2 is subjected to a vertical force at the center toggle 5, it deforms downwards. When the deformation reaches a certain level, the horizontal air guide blade 2 contacts the arc-shaped support 3. The arc-shaped support 3 provides vertical support to the horizontal air guide blade 2, preventing further deformation and damage or blade detachment.

[0048] The arc-shaped support 3 also meets the angle adjustment requirements of the horizontal guide vane 2. The arc groove 31 is clearance-fitted with the horizontal guide vane 2, and the center of the arc groove 31 is located on the rotation axis of the horizontal guide vane 2. The arc groove 31 of the arc-shaped support 3 is coaxial with the rotation axis of the horizontal guide vane 2. Under normal conditions, the horizontal guide vane 2 and the arc-shaped support 3 maintain an appropriate movement clearance, which does not affect the angle adjustment function of the horizontal guide vane 2. The movement of the horizontal guide vane 2 does not interfere with the arc-shaped support 3, thus meeting the operational requirements of the horizontal guide vane 2.

[0049] In some alternative embodiments: see Figures 1 to 4 and Figure 7 As shown in the figure, this application embodiment provides an extra-long single-blade air outlet structure for automotive air conditioning. The arc-shaped support 3 of this extra-long single-blade air outlet structure is a sheet structure with a set thickness. The arc-shaped support 3 is an injection-molded part with a thickness of 2-3mm to reduce the obstruction of airflow at the air outlet port 11. The arc-shaped support 3 is vertically connected to the air outlet housing 1, and buckles 32 for connecting to the air outlet housing 1 are provided on both the top and bottom surfaces of the arc-shaped support 3.

[0050] The air outlet port 11 of the air outlet housing 1 has a rectangular structure. Slots adapted to the snap fasteners 32 of the arc-shaped support 3 are provided on both the upper and lower edges of the air outlet port 11. When the snap fasteners 32 of the arc-shaped support 3 are engaged in the slots of the air outlet housing 1, the arc-shaped support 3 is fixedly connected to the air outlet housing 1. The snap fastener 32 is preferably, but not limited to, a frustum or trapezoidal boss protruding from the top or bottom surface of the arc-shaped support 3. The cross-sectional area of ​​the frustum or trapezoidal boss gradually decreases towards the surface away from the top or bottom surface of the arc-shaped support 3, so as to facilitate the smooth engagement of the arc-shaped support 3 onto the air outlet housing 1.

[0051] The top and bottom surfaces of the arc-shaped support 3 are provided with tension pins 33 that connect to the air outlet housing 1. The tension pins 33 are in the shape of a "T". The upper and lower edges of the air outlet port 11 of the air outlet housing 1 are provided with notches that are adapted to the tension pins 33 of the arc-shaped support 3. When the tension pins 33 of the arc-shaped support 3 are inserted into the notches of the air outlet housing 1, the arc-shaped support 3 maintains a constant distance between the upper and lower edges of the air outlet port 11 of the air outlet housing 1 to prevent deformation of the air outlet port 11 structure.

[0052] In some alternative embodiments: see Figures 1 to 4 and Figure 7 As shown in the illustration, this application provides an ultra-long single-blade air outlet structure for automotive air conditioning. This structure includes two or more arc-shaped support bases 3, the specific number of which is determined based on the structural strength and length of the horizontal air guide blade 2. This application uses two symmetrically arranged horizontal air guide blades 2 as an example for illustration. The two arc-shaped support bases 3 are arranged alternately along the length of the horizontal air guide blade 2. The windward surface of the horizontal air guide blade 2 is an arc surface, and the center of the arc surface is located on the rotation axis of the horizontal air guide blade 2.

[0053] The distance between the arc surface of the horizontal guide vane 2 and the arc groove 31 of the arc support 3 is 0.1 to 1 mm, more preferably 0.5 mm. The angle corresponding to the arc groove 31 of the arc support 3 is greater than the rotation angle of the horizontal guide vane 2, so that the arc support 3 can always provide support and protection for the horizontal guide vane 2 when it rotates at any angle. In this embodiment, there are two horizontal guide vanes 2, which are located on both sides of the knob 5 and symmetrically arranged. The distance between the two arc support 3 and the adjacent blade bearing seat 4 is about 70 mm. The windward surface of the horizontal guide vane 2 is an arc surface, and the center of the arc surface is located on the rotation axis of the horizontal guide vane 2, so that the distance between the windward surface of the horizontal guide vane 2 and the arc support 3 is the same.

[0054] When the horizontal guide vane 2 touches the arc-shaped support 3 downwards, the arc groove 31 of the arc-shaped support 3 provides vertical support to the horizontal guide vane 2, preventing further deformation and damage or blade detachment. In this application, the maximum deformation of the horizontal guide vane 2 is required to be <3.5mm. When the horizontal guide vane 2 is at the position of the arc-shaped support 3, and the deformation of the horizontal guide vane 2 under force reaches 1.1mm, the arc groove 31 of the arc-shaped support 3 provides support to the horizontal guide vane 2, preventing further deformation.

[0055] In some alternative embodiments: see Figures 1 to 3As shown in the figure, this application embodiment provides an ultra-long single-blade air outlet structure for automotive air conditioning. The air outlet of this automotive air conditioning ultra-long single-blade air outlet structure also includes blade bearing seats 4 located at both ends of the horizontal guide blade 2 and fixed on the air outlet housing 1. Metal shafts 23 are provided at both ends of the horizontal guide blade 2 and are rotatably connected to the blade bearing seats 4. The metal shafts 23 are preferably, but not limited to, steel shafts with a diameter of 2mm. One end of the metal shaft 23 is embedded in the horizontal guide blade 2 during injection molding, and the other end of the metal shaft 23 extends out of the horizontal guide blade 2.

[0056] A decorative strip 41, matching the cross-sectional shape of the horizontal guide vane 2, is provided on the blade bearing housing 4. Mounting holes 42 for rotatably connecting metal shafts 23 are provided on the decorative strip 41. The metal shafts 23 at both ends of the horizontal guide vane 2 extend into the mounting holes 42 and rotate freely relative to the blade bearing housing 4. An arc-shaped limiting groove 43 is provided on the blade bearing housing 4 near the end of the horizontal guide vane 2. Limiting rods 24 extending into the arc-shaped limiting groove 43 are also provided at both ends of the horizontal guide vane 2.

[0057] In this embodiment, metal shafts 23 are provided at both ends of the horizontal guide vane 2, which are rotatably connected to the blade bearing seat 4. These metal shafts 23 serve as the pivot connecting the horizontal guide vane 2 to the blade bearing seat 4. Compared to a plastic pivot integrally injection-molded with the horizontal guide vane 2, this embodiment optimizes the plastic pivot into a metal shaft 23. The metal shaft 23 has higher structural strength than the plastic pivot, and its diameter is smaller, which is beneficial for improving structural connection strength and service life. The arc-shaped limiting groove 43 on the blade bearing seat 4 is used to limit the rotation angle range of the horizontal guide vane 2. When the horizontal guide vane 2 rotates to its limit position, the limiting rods 24 at both ends of the horizontal guide vane 2 abut against either end of the arc-shaped limiting groove 43.

[0058] In some alternative embodiments: see Figures 1 to 3 As shown in the figure, this application embodiment provides an extra-long single-blade air outlet structure for automotive air conditioning. The horizontal guide vane 2 of this structure, near the blade bearing seat 4, is fitted with a decorative strip 41 to conceal the metal shaft 23. The center of the arc-shaped limiting groove 43 is located on the rotation axis of the horizontal guide vane 2. The metal shaft 23 is hidden at the connection point between the horizontal guide vane 2 and the decorative strip 41, improving the appearance quality of the extra-long single-blade air outlet structure. The center of the arc-shaped limiting groove 43, located on the rotation axis of the horizontal guide vane 2, allows the horizontal guide vane 2 to rotate freely and flexibly.

[0059] In some alternative embodiments: see Figures 4 to 6As shown in the figure, this application embodiment provides an ultra-long single-blade air outlet structure for automotive air conditioning. The horizontal guide vane 2 of this automotive air conditioning ultra-long single-blade air outlet structure includes an outer guide vane 21. The windward surface of the outer guide vane 21 is provided with an elongated groove extending along the length direction of the outer guide vane 21. The cross-section of the outer guide vane 21 has a "U" shaped structure. A reinforcing frame 22 is embedded in the elongated groove of the outer guide vane 21, and the reinforcing frame 22 is interlocked with the outer guide vane 21.

[0060] In this embodiment, the outer guide vane 21 of the horizontal guide vane 2 adopts a hollow design, and a reinforcing frame 22 is embedded in the elongated groove of the outer guide vane 21. The reinforcing frame 22 improves the structural rigidity of the outer guide vane 21. The reinforcing frame 22 can be made of nylon plastic or aluminum alloy. The reinforcing frame 22 serves as an internal reinforcing frame for the outer guide vane 21 to improve the structural rigidity of the outer guide vane 21 and enhance its bending and crack resistance.

[0061] The reinforcing frame 22 and the outer guide vane 21 are interlocked for easy assembly. The top and bottom surfaces of the reinforcing frame 22 are each provided with snap-fit ​​protrusions 25 that snap into the outer guide vane 21. Multiple snap-fit ​​protrusions 25 are provided, spaced apart sequentially along the length of the reinforcing frame 22. The inner surface of the outer guide vane 21 has multiple grooves that mate with the snap-fit ​​protrusions 25.

[0062] In some alternative embodiments: see Figure 5 and Figure 6 As shown in the figure, this application embodiment provides an ultra-long single-blade air outlet structure for automotive air conditioning. The reinforcing frame 22 of this structure has multiple positioning slots 26 on the side facing away from the windward side. Multiple positioning plates are respectively located within the positioning slots 26 in the elongated slots of the outer air guide blade 21. When the positioning plates are inserted into the positioning slots 26, they restrict the left and right movement of the reinforcing frame 22 within the elongated slots of the outer air guide blade 21.

[0063] The top and bottom surfaces of the reinforcing frame 22 are provided with limiting ribs 27 that insert into the inner wall of the outer guide vane 21. These limiting ribs 27 restrict the reinforcing frame 22 from moving up and down within the elongated groove of the outer guide vane 21. Multiple limiting protrusions are provided at the bottom of the elongated groove that abut against the reinforcing frame 22. These limiting protrusions restrict the reinforcing frame 22 from moving back and forth within the elongated groove of the outer guide vane 21.

[0064] In some alternative embodiments: see Figures 3 to 6As shown, this application embodiment provides an ultra-long single-blade air outlet structure for automotive air conditioning. The air outlet of this ultra-long single-blade air outlet structure for automotive air conditioning also includes multiple vertical air guide blades 6 that can rotate in linkage within the air outlet port 11 of the air outlet housing 1. The number of vertical air guide blades 6 is specifically set according to the width of the air outlet port 11. This application embodiment takes nine vertical air guide blades 6 as an example for distance description. The nine vertical air guide blades 6 are arranged sequentially at intervals along the width direction of the air outlet port 11.

[0065] Each of the nine vertical guide vanes 6 has a rotating shaft at its top and bottom that is rotatably connected to the outlet housing 1. The vertical guide vanes 6 rotate within the outlet housing 1 to adjust the airflow and direction. The nine vertical guide vanes 6 are also connected by a connecting plate (not shown in the figure). When one vertical guide vane 6 rotates, the connecting plate simultaneously drives the other vertical guide vanes 6 to rotate synchronously in the same direction and angle. A lever 5 is slidably connected to the horizontal guide vane 2, and the lever 5 is connected to any of the vertical guide vanes 6 via a lever fork 7.

[0066] A guide groove 28 is provided on the windward side of the reinforcing frame 22, and the lever 5 slides back and forth within the length of the guide groove 28. The guide groove 28 is used to limit the range of motion of the lever 5 on the horizontal guide vane 2. When the lever 5 slides to the left limit position of the guide groove 28, the lever 5 drives the vertical guide vane 6 to rotate to the left to the limit angle through the lever fork 7. When the lever 5 slides to the right limit position of the guide groove 28, the lever 5 drives the vertical guide vane 6 to rotate to the right to the limit angle through the lever fork 7.

[0067] Working principle

[0068] This application provides an ultra-long single-blade air outlet structure for automotive air conditioning. The ultra-long single-blade air outlet structure of this application includes an air outlet housing 1. A rotatable horizontal guide vane 2 is provided at the air outlet port 11 of the air outlet housing 1. An arc-shaped support 3 is connected to the air outlet port 11 of the air outlet housing 1. An arc groove 31 is provided on the windward side of the arc-shaped support 3 near the horizontal guide vane 2. The arc groove 31 is clearance-fitted with the horizontal guide vane 2, and the center of the arc groove 31 is located on the rotation axis of the horizontal guide vane 2.

[0069] Therefore, to ensure sufficient rigidity and strength of the horizontal air guide blade 2 when subjected to excessive force in the vertical direction, the present application adds an arc-shaped support 3 to the air outlet port 11 of the air outlet housing 1. When the horizontal air guide blade 2 is subjected to a vertical force at the center toggle 5, it deforms downward. When the deformation reaches a certain level, the horizontal air guide blade 2 touches the arc-shaped support 3 downward. The arc-shaped support 3 provides vertical support to the horizontal air guide blade 2, preventing further deformation and damage or blade detachment.

[0070] The arc-shaped support 3 also meets the angle adjustment requirements of the horizontal guide vane 2. The arc groove 31 is clearance-fitted with the horizontal guide vane 2, and the center of the arc groove 31 is located on the rotation axis of the horizontal guide vane 2. The arc groove 31 of the arc-shaped support 3 is coaxial with the rotation axis of the horizontal guide vane 2. Under normal conditions, the horizontal guide vane 2 and the arc-shaped support 3 maintain an appropriate movement clearance, which does not affect the angle adjustment function of the horizontal guide vane 2. The movement of the horizontal guide vane 2 does not interfere with the arc-shaped support 3, thus meeting the operational requirements of the horizontal guide vane 2.
