Technical Field
[0001] This invention relates to the technology of air outlet for car heating and cooling fans, and particularly to a manual dual-channel air outlet for car heating and cooling fans. Background Technology
[0002] With the rapid advancements in car manufacturing technology, the air vents of car heaters and air conditioners have undergone various transformations. From decorative round vents to easily adjustable rectangular vents; from single-channel to dual-channel vents. The control methods for these vents have also diversified. Currently, the most popular and widely used vent is the dual-channel vent. A dual-channel vent typically refers to an vent with upper and lower air channels, using upper and lower guide vanes inside the vent to separate the airflow. Furthermore, most manual vents on car heaters and air conditioners on the market have the control knob for rotating the guide vanes located in the center of the vent (see Appendix). Figure 1 Because the knob controlling the rotation of the upper and lower air deflectors is located in the middle of the air outlet, it not only affects the aesthetics but may also create air resistance. Furthermore, its structure is complex and occupies a large amount of space; and the separate mechanism for controlling the opening and closing of the damper requires control inputs from multiple locations to adjust the airflow direction at the outlet.

Figure 3 This is a three-dimensional schematic diagram of the present invention from another perspective, attached. Figure 4 This is a longitudinal sectional view of the present invention, attached. Figure 5 This is a rear-part exploded three-dimensional schematic diagram of the present invention, attached. Figure 6This is a three-dimensional schematic diagram of the air baffle and air guide plate fixing components of the present invention; in the figure, 1 is the housing, 2 is the panel, 3 is the air inlet cover, 4 is the left and right air guide components, 5 is the upper and lower air guide plates, 6 is the air baffle, 6-1 is the bayonet notch, 7 is the air guide plate fixing component, 7-1 is the upper and lower air guide plate rotation shaft hole, 7-2 is the tongue plate, 8 is the knob assembly, 9 is the left and right drive assembly, and 10 is the upper and lower drive assembly. As shown in the figure, the manual dual-channel air outlet of the car's air conditioning and heating fan of the present invention includes a housing 1, a panel 2, an air inlet hood 3, left and right air guide components 4, upper and lower air guide plates 5, an air baffle 6, an air guide plate fixing component 7, a knob assembly 8, a left and right drive assembly 9, and an upper and lower drive assembly 10. The housing 1 has a rectangular cross-sectional shape, with a semi-circular front and a rectangular rear longitudinal section. The panel 2 is rectangular and is located at the front end of the air outlet of the housing. The air inlet hood 3 has a rectangular cross-sectional shape, with a longitudinal section that gradually decreases in size from back to front and then gradually increases in size, and the front end of the air inlet hood is sealed to the rear end of the housing. The left and right air guide components 4 are located at the front of the housing. The upper and lower air guide plates 5 are long rectangular strips, with a rotating shaft at the right end of the inner long side of the upper and lower air guide plates and a rotating shaft hole at the left end of the inner long side of the upper and lower air guide plates. The air baffle 6 has a hollow fishback-shaped cross-sectional shape. The air baffle plate is located in the middle of the front side of the left and right air guide components. The fish-back shaped front end of the air baffle plate extends out of the front side of the left and right air guide components, and the rear end is provided with a notch. The air guide plate fixing component 7 is located on the rear side of the air baffle plate and is long and narrow. The left and right ends of the long and narrow air guide plate fixing component are provided with upper and lower air guide plate rotation shaft holes, and the left air guide plate rotation shaft hole is a through hole. The front side of the long and narrow air guide plate fixing component is provided with tongue plates whose number, position and shape match the notch at the rear end of the air baffle plate. The rear side of the air baffle plate and the front side of the air guide plate fixing component are sealed and fastened to each other by a buckle, so that the air baffle plate and the air guide plate fixing component form a whole, and the notch and the tongue plate are fastened to form the rotation shaft hole of the blades of the left and right air guide components. The knob component 8, the left and right drive component 9 and the upper and lower drive component 10 are all located on the right side of the housing, respectively driving the left and right air guide components to rock left and right and the upper and lower air guide plates to swing up and down. The longitudinal cross-section of the manual dual-channel air outlet housing of the car's heating and cooling fan of this invention is semi-circular at the front and rectangular at the rear. Furthermore, the longitudinal cross-section of the air inlet shroud gradually decreases from back to front and then gradually expands, with the front end of the air inlet shroud sealingly connected to the rear end of the housing. This results in a relatively higher airflow velocity before the air is split into upper and lower sections, and a relatively lower airflow velocity during delivery, effectively improving the airflow guidance effect while ensuring comfort. Simultaneously, the left and right air guide components are positioned at the front of the housing, and the upper and lower air guide plates are positioned behind the left and right air guide components, ensuring that the upper and lower air guides and the left and right air guides are adjacent and located at positions where the airflow velocity increases, thereby significantly enhancing the airflow guidance effect.In addition, the airflow adjustment mechanism is located on the right side of the air outlet. At the same time, the control functions of vertical airflow, horizontal airflow, and damper closure are integrated into one component, which simplifies the structure, facilitates operation, increases aesthetics, and reduces wind resistance.
[0028] Appendix Figure 7 This is a three-dimensional schematic diagram of a single blade of the present invention, attached. Figure 8 This is a three-dimensional schematic diagram of the left and right air guide components of the present invention, attached. Figure 9This is an exploded three-dimensional schematic diagram of the left and right air guide components of the present invention when closed; in the figure, 4-1 is a blade, 4-2 is a rocking plate, 4-3 is a connecting plate, 5 is an upper and lower air guide plate, 6 is a wind baffle plate, 7 is an air guide plate fixing component, 8 is a knob assembly, 9 is a left and right drive assembly, and 10 is an upper and lower drive assembly. As shown in the figure, the left and right air guide components of the manual dual-channel air outlet of the car's air conditioning and heating fan of the present invention include blades 4-1, rocking plates 4-2, and connecting plates 4-3. The blades 4-1 consist of several pieces, are rectangular in shape, and have an upper and lower section structure. A rotating shaft is provided on the central axis between the two blade sections. Furthermore, the connecting shaft extends from the outer end faces of the upper and lower blade sections to form rocking shafts. A connecting arm is connected to the left side of the rear edge of the upper and lower blade sections. The connecting arm is L-shaped, with one end fixed to the left side of the upper and lower blade sections and the other end serving as the connecting shaft. The rocking plates 4-2 consist of two pieces, each shaped like a long, toothed plate, with a rocking groove formed by the gap between the two teeth. The number of rocking grooves corresponds to the number of blades. Similarly, a notch is provided at the root of the rocking groove to engage with the rocking shaft of the blade; the connecting plate 4-3 consists of two pieces, which are long strip toothed plates, and a connecting shaft hole is provided at the end of each toothed plate, and the number of toothed plates is the same as the number of blades; during installation, the rotating shaft in the middle of each blade 4-1 is fitted into the rotating shaft hole formed by the notch of the windbreak plate 6 and the tongue plate of the wind guide plate fixing piece 7 after being engaged; the two rocking plates 4-2 are respectively set at the upper and lower ends of the blade with their teeth facing backward, and the notches at the root of their rocking grooves are respectively engaged with the rocking shaft at the end of the blade; the two connecting plates 4-3 are respectively set at the upper and lower ends of the blade with their teeth facing forward, and the connecting shaft holes at the ends of their toothed plates are respectively fitted into the connecting shaft on the left side of the blade. The manual dual-channel air outlet of this invention for a car's air conditioning and heating fan has a two-section structure, with upper and lower air guide plates and a baffle plate respectively positioned at the rear and front sides of the rotating shaft between the upper and lower blade sections. This arrangement of the upper and lower air guide plates, left and right air guide components, and fixed baffle plate, adjacent to and intersecting each other, effectively achieves vertical airflow separation and allows for lateral adjustment of the separated airflow direction. Simultaneously, it results in a compact overall structure, a simple airflow path, and significantly reduced wind resistance. Furthermore, the manual dual-channel air outlet of this invention uses a mutually sealing and interlocking baffle plate and air guide plate fixing component as the support for the left and right air guide components. The rotating shaft between the upper and lower blade sections is directly fitted into the rotating shaft hole formed by the engagement of the baffle plate's notch and the baffle plate's tongue plate. This ingenious structure contributes to a very compact overall design. Moreover, the upper and lower ends of all blades in the manual dual-channel air outlet of this invention's manual dual-channel air outlet are relatively fixed and linked via a rocking plate and a connecting plate, ensuring the consistency and reliability of the blade rocking. It should be noted that the connecting arm of the left and right air guide assembly of the manual dual-channel air outlet of the car's air conditioning and heating fan of the present invention adopts an L-shaped structure, so that when the blade group swings to the left, the adjacent blades can fully contact each other, and all the blades contact each other to form a continuous sealing structure, just like the damper closing structure.
[0029] Appendix Figure 10 This is a three-dimensional schematic diagram of the knob assembly of the present invention, with accompanying drawings. Figure 11 This is an exploded three-dimensional schematic diagram of the knob assembly of the present invention. In the figure, 4-3 is the linkage plate, 6 is the wind baffle plate, 8-1 is the bracket, 8-2 is the rotary rod, 8-3 is the knob, 8-4 is the rotary arm, 9-1 is the drive arm of the left and right drive assembly, and 10-1 is the rocker arm of the up and down drive assembly. As shown in the figure, the knob assembly 8 of the manual dual-channel air outlet of the car air cooler of the present invention is fixed on the right outer side of the housing, including a bracket 8-1, a rotary rod 8-2, a knob 8-3, and a rotary arm 8-4; the bracket 8-1 has an L-shaped structure, with one end being a fixed seat and the other end being a rotating seat; support plates and buckles that connect to the housing are provided on both sides of the fixed seat extending outward; a rotating hole is provided in the middle of the rotating seat, a radial column is provided on the inner wall of the rotating hole, and two arc-shaped grooves are symmetrically provided on the outer side of the rotating hole; the rotary arm 8-4 has a spoon-shaped structure, with the spoon body being a rotating disk and the spoon handle being a rotating part. The arm; the rotating disk is a hollow disc structure, with an axially extending buckle on the front end face of the rotating disk. The buckle engages in the arc-shaped groove of the bracket rotating seat and rotates within the arc-shaped groove; a radial column for engaging the rotating rod is provided on the inner wall of the rotating disk; and an axial column is provided at the front end of the rotating arm; the rotating rod 8-2 is a cylindrical structure, with its outer diameter matching the inner diameter of the cantilever rotating disk; the front end of the rotating rod is a hollow column, with a groove in the radial direction of the hollow column, which slides and engages with the radial column on the inner wall of the cantilever rotating disk; the knob 8-3 is fixed to the rear end of the rotating rod. The knob assembly of the manual dual-channel air outlet of the car's air conditioning and heating fan of this invention uses a snap-fit and sliding engagement structure for installation and cooperation, simplifying the installation process and operation. The bracket serves as the overall foundation, not only for the installation and fixing of other components, but also for the positioning and movement of other components. The fixed installation and rotational positioning of the rotating arm are achieved through the arc-shaped groove set on the outer side of the rotating hole of the bracket rotating seat; the swing positioning of the upper and lower drive component swing arm is achieved through the column set on the inner wall of the rotating hole of the bracket rotating seat. The installation and positioning of the upper and lower drive component swing arm is achieved through the hollow column set on the front end of the rotating rod.
[0030] Appendix Figure 12 This is a three-dimensional schematic diagram of the left and right drive components of the present invention, attached. Figure 13This is a three-dimensional schematic diagram of the drive arm of the left and right drive assembly of the present invention; in the figure, 4-1 is a blade, 4-2 is a rocking plate, 6 is a wind deflector, 8-4 is a knob assembly arm, 9-1 is a drive arm, and 9-2 is a drive rod. As shown in the figure, the left and right drive assembly of the manual dual-channel air outlet of the car air cooler of the present invention includes a drive arm 9-1 and a rocking rod 9-2; the drive arm 9-1 is L-shaped, with a drive plate at one end, and an arc-shaped groove at the lower part of the drive plate that slides and engages with the axial column of the front end of the rotary arm, and a rocking through hole at the other end; the rocking rod 9-2 is S-shaped, with both ends extending outward, one end of which is fixedly connected to the rocking shaft at the upper end of the rightmost blade of the left and right air guide assembly, and the other end is a column hinged to the rocking through hole of the drive arm. The left and right drive assembly of the manual dual-channel air outlet of the car's air conditioning and heating fan of this invention has a very simple structure. An arc-shaped groove is provided at the lower part of the drive plate of the drive arm, which slides and engages with the axial column at the front end of the knob assembly's rotating arm, thereby converting the vertical circular motion of the rotating arm column into the horizontal motion of the rocking through-hole at the other end of the drive arm. One end of the S-shaped rocking rod is fixedly connected to the rocking shaft at the upper end of the rightmost blade of the left and right air guide assembly, and the other end is hinged to the end of the drive arm. The rocking rod effectively becomes a linkage lever for the rocking shaft of the rightmost blade of the left and right air guide assembly. Driven by the horizontal motion of the end of the drive arm, the rightmost blade of the left and right air guide assembly will rock left and right about the rotation axis. Under the action of the linkage plates at the upper and lower ends of the blades of the left and right air guide assembly, all blades will rock left and right at a uniform angle and remain at the set position. Furthermore, the rotation direction of the knob of the left and right drive assembly of this invention is consistent with the airflow adjustment direction; that is, when the knob is rotated to the left, the airflow is directed to the left; conversely, it is directed to the right.
[0031] Appendix Figure 14 This is a three-dimensional schematic diagram of the upper and lower drive components of the present invention, attached. Figure 15This is a three-dimensional schematic diagram of the drive gear of the upper and lower drive assembly of the present invention; in the figure, 5 is the upper and lower air guide plate, 7 is the air guide plate fixing part, 10-1 is the swing arm, 10-2 is the drive gear, and 10-3 is the driven gear. As shown in the figure, the upper and lower drive assembly 10 of the manual dual-channel air outlet of the car air cooler of the present invention includes a swing arm 10-1, a drive gear 10-2, and a driven gear 10-3. The swing arm 10-1 is elongated, with its rear end inserted into the hollow cylinder at the front end of the rotating rod and rotatably engaged. A circular hole matching the radial cylinder on the inner wall of the rotating hole of the bracket is provided in the radial direction in the middle of the swing arm. The front end is rectangular and has an arc groove on the left side. A circular support plate is provided on the left side of the drive gear 10-2. A support column coaxial with the gear is provided on the left side of the circular support plate. A lever extends radially from the circular support plate. A cylinder that slides and engages with the arc groove on the left side of the front end of the swing arm is provided on the right side of the lever. The driven gear 10-3 meshes with the drive gear and has an upper and lower rotating shaft extending on the left side. The upper and lower rotating shaft passes through the upper and lower air guide plate rotating shaft hole on the left rear side of the air guide plate fixing component and is fixedly inserted into the rotating shaft hole at the left end of the upper and lower air guide plates. This invention relates to a manual dual-channel air outlet drive assembly for a car's heating and cooling fan. The assembly utilizes a gear structure to convert the up-and-down swing of the rocker arm into the rotation of the upper and lower air guide plates, synchronizing the operation of the rocker arm with changes in airflow direction; that is, when the rocker arm is moved upwards, air is also directed upwards. A circular hole in the middle of the rocker arm, matching the radial column on the inner wall of the rotating hole of the support, is cleverly designed to position the rocker arm during its up-and-down movement. The multi-functional structure of the drive gear further simplifies manufacturing and assembly. A column on the right side of the drive gear's actuation lever matches the arc-shaped groove on the left side of the rocker arm's front end, effectively converting the misaligned swing of the rocker arm and drive gear into the rotation of the drive gear. The rotation of the drive gear then drives the rotation of the driven gear, thereby rotating the upper and lower air guide plates.
[0032] Obviously, the beneficial technical effect of the manual dual-channel air outlet of the car air cooler of the present invention is that the air direction adjustment mechanism is set on the right side of the air outlet. At the same time, the control functions of vertical air guiding, horizontal air guiding and air damper closing are integrated into one component, which simplifies the structure, facilitates operation, increases aesthetics and reduces wind resistance.
