[0041] The ventilation device 100 includes a retaining frame 109, an air guide unit 102, a baffle 103, an air guide unit driving device 104, and a baffle driving device 105. The air guide unit 102 is mounted on the retaining frame 109 and is driven by the air guide unit driving devices 104 and 124 to move. The baffle 103 is mounted on the retaining frame 109 and is driven by the baffle driving device 105 to rotate to cover or expose the air guide unit 102 and simultaneously close or open the air outlet 703 on the vehicle interior panel (see FIG. Figure 7A Two adjacent guide units 102 are connected side by side to form a guide unit group 122.

[0042] Figure 2A is a perspective view of the holding frame 109, Figure 2B yes Figure 2A A perspective view of another angle of the holding frame shows the structure of the holding frame 109. Figure 2A and Figure 2BThe retaining frame 109 includes an upper portion 231, a lower portion 232, and a pair of side portions 233. The upper portion 231, lower portion 232, and pair of side portions 233 define an air guide unit mounting channel 208. The air guide unit 102 can be mounted in the air guide unit mounting channel 208 and can move relative to the retaining frame 109. The retaining frame 109 has a front end 211 and a rear end 212. The air guide unit mounting channel 208 extends through the front end 211 and the rear end 212. The rear end 212 can communicate with the air conditioning outlet and form a seal, allowing all or most of the air conditioned air to enter the ventilation device 100. The air guide unit 102 also includes three drive device supports 241, 242, and 243, which are evenly distributed between a pair of side portions 233, dividing the air guide unit installation channel 208 into four areas 261, 262, 263, and 264. Area 261 is used to install a single air guide unit 102, areas 263 and 264 are used to install an air guide unit group 122 consisting of two air guide units 102, and area 262 is used to arrange other components within the vehicle interior. In this embodiment, the regional layout of the air guide unit installation channel 208 is related to the spatial layout of the vehicle interior. In other embodiments, the configuration can be based on the interior space arrangement of the vehicle. The drive device support 243 is located in the middle of the air guide unit 103 and is used to install the baffle motor drive device 105. The drive device supports 241 and 242 are located on either side of the drive device support 243 and are used to install the air guide unit drive device 104. The drive device support portion 243 is located near the front end 211 of the retaining frame 109, while the drive device supports 241 and 242 are located near the rear end 212 of the retaining frame 109. The drive device supports 241, 242, and 243 each include a pair of side panels 271 and 272, with a spacing therebetween for accommodating the corresponding drive device.

[0044] Figure 3A yes Figure 2B A perspective view of a guide unit 102, Figure 3B This is a three-dimensional image of the diversion unit in 3A from another angle. Figure 3A and Figure 3B The structure of the flow guiding unit is described by taking a flow guiding unit 102 as an example. Figure 3A and Figure 3B As shown, the air guide unit 102 has a depth direction D1 and a length direction L1. The air guide unit 102 includes an air guide unit housing 321 with two open ends. The air guide unit housing 321 is roughly cubical and has an upper portion 322, a lower portion 323, and a pair of side portions 324. The upper portion 322, the lower portion 323, and the pair of side portions 324 form a air guide channel 305, which extends along the depth direction of the air guide unit 102. The two ends of the air guide unit housing 321 respectively constitute the inlet end 301 and the outlet end 302 of the air guide unit 102. The air guide channel 305 has an air guide inlet 351 and an air guide outlet 352, which are formed by the inlet end 301 and the outlet end 302, respectively. When the air guide unit 102 is installed in the retaining frame 109, the air guide channel inlet 351 is close to the front end 211 of the retaining frame, and the air guide outlet 352 is close to the rear end 212 of the retaining frame. The guide channel 305 is provided with rotatable horizontal blades 317 and vertical blades ( Figure 3A (not shown) for adjusting the direction of the airflow in the guide channel 305. The outer shape of the outlet end 302 matches the shape of the vehicle interior panel to form a smooth transition curve. In this embodiment, the outlet end 302 is an arc shape.

[0045] A guide unit rack 318 is provided on the outer side of the upper portion 322 of the guide unit housing 321, and a guide unit rack 319 is provided on the outer side of the lower portion 323 of the guide unit housing 321. The guide unit racks 318 and 319 extend along the depth direction of the guide unit 102. In the longitudinal direction L1 of the guide unit 102, the guide unit racks 318 and 319 are respectively located in the middle of the guide unit housing 321. In the depth direction D1 of the guide unit housing 321, the guide unit racks 318 and 319 are both located near the inlet end 301, facilitating cooperation with the guide unit drive device 104 mounted at the rear end of the retaining frame 109. When the guide unit 102 is installed in the retaining frame 109, the guide unit racks 318 and 319 are aligned with the pair of hollow portions 260. The air guiding unit rack 318 and the air guiding unit rack 319 respectively have a front end 362 and a rear end 363 , wherein the rear end 362 is closer to the inlet end 301 than the front end 363 .

[0046] Figure 4is a perspective view of the guide unit driving device 104, as shown in Figure 4 As shown, the diversion unit drive device includes a diversion unit motor 401 and a diversion unit transmission component. The diversion unit transmission component includes a motor gear set 403, a pair of connecting rods 405, a pair of connecting rod gears 417 and 418, and a pair of diversion unit drive gears 407 and 408. The motor gear set includes a first gear 413, a pair of second gears 415, and a fourth gear 419. The first gear 413 is fixedly connected to the diversion unit motor 401 via a shaft 423, so that the diversion unit motor 401 can drive the shaft 423 to rotate, thereby rotating the first gear 413. The pair of second gears 415 are connected to the drive device support 241 via a second gear shaft and can rotate relative to the drive device support 241 around the second gear shaft. Each of the pair of second gears 415 has an inner gear 433 and an outer gear 434, and the central axes of the inner gear 433 and the outer gear 434 are the same. The outer diameter of the inner gear 433 is smaller than that of the outer gear 434, which in turn is larger than that of the first gear 413. The pair of outer gears 434 mesh with the first gear 413. One of the inner gears 433 meshes with the connecting rod gear 418, and the other meshes with the fourth gear 419. The fourth gear 419 meshes with the connecting rod gear 417, so that when the air diversion unit motor 401 drives the shaft 423 to rotate, it simultaneously drives the pair of connecting rod gears 417 and 418 to rotate. Each of the pair of connecting rods 405 has one end fixedly connected to each of the pair of connecting rod gears 417 and 418, and the other end fixedly connected to each of the pair of air diversion unit gears 407 and 408. Therefore, the rotation of the pair of connecting rod gears 417 and 418 drives the pair of air diversion unit gears 407 and 408 to rotate. Each of the pair of air guide unit gears 407 and 408 meshes with the air guide unit rack 318 and the air guide unit rack 319, respectively, so that the rotation of the air guide unit gears 407 and 408 can drive the rotation of the air guide unit 102. In this embodiment, the connecting rod gears 417 and 418 and the air guide unit drive gears 407 and 408 are respectively located at both ends of the connecting rod 405, and the connecting rod gears 417 and 418 and the air guide unit drive gears 407 and 408 are fixedly connected to the connecting rod 405, so that the movement of the air guide unit motor 401 can be transmitted to the air guide unit 102 through the connecting rod 405, thereby driving the movement of the air guide unit 102. With the configuration of the connecting rod 405, the air guide unit motor 401 can be disposed on one side of the air guide unit 102, thereby saving space in the ventilation device in the vertical and horizontal directions.

[0047] In this embodiment, the fourth gear 419 is provided to coordinate with the position of the connecting rod gear 418. In other embodiments, if the connecting rod gear 418 can directly mesh with the inner gear 433, the fourth gear is not required. In this embodiment, the multiple gears in the motor gear set 403 are used to achieve the desired movement speed of the diversion unit 102. The movement speed of the diversion unit 102 is achieved by the coordination of the gears of different sizes in the motor gear set 403. In other embodiments, the gears in the motor gear set 403 can be configured in other combinations as needed.

[0048] In this embodiment, a pair of connecting rods 405, a pair of connecting rod gears 417 and 418, and a pair of diversion unit drive gears 407 and 408 are provided, which respectively cooperate with the diversion unit racks 318 and 319 on the upper and lower surfaces of the diversion unit 102 to simultaneously drive the movement of the diversion unit 102. This arrangement can ensure smoother movement of the diversion unit 102. In other embodiments, when the diversion unit 102 is provided with only one diversion unit rack, the diversion unit drive device 105 also only requires one connecting rod 405, one connecting rod gear 417 and 418, and one diversion unit drive gear 407.

[0049] exist Figure 3A-Figure 4 The figure shows the guide unit 102 and the guide unit driving device 104 that cooperates with it. Figure 1B As shown, the ventilation device 100 further includes a guide unit group 122 and a guide unit driving device 124 coordinated therewith. The guide unit group 122 consists of two Figure 3A The guide units 102 are connected side by side. Compared with the guide unit drive device 104, the guide unit drive device 124 is provided with a pair of guide unit drive gears at each end of the connecting rod, which respectively engage with the two guide units 102. A pair of connecting rod gears is set in the middle of the connecting rod. The guide unit motor drives the pair of connecting rod gears to rotate through the motor gear set, thereby driving the pair of guide unit drive gears at each end of the connecting rod to rotate, thereby driving the two guide units 102 to rotate. In other words, the two guide units 102 in the guide unit group 122 are driven to move by a guide unit motor. In other embodiments, a guide unit motor can also drive more guide units to move together in a similar manner.

[0050] Figure 5 yes Figure 1B The perspective view of the baffle 103 is used to illustrate the structure of the baffle 103, such as Figure 5As shown, the baffle 103 includes a main body 501 and a connecting portion 502. The main body 501 is generally elongated and has an inner side 511 and an outer side 512. The main body 501 is used to seal a long air outlet. The outer side of the main body 501 matches the shape of the vehicle interior panel, forming a continuous surface with the vehicle interior panel. The main body 501 has a length direction L2 and a width direction W2. There are three connecting portions 502, each connected to the inner side 511 of the main body 501 and extending beyond the edge of the main body 501 along the width direction of the main body 501. The three connecting portions 502 are evenly distributed along the length direction L2 of the main body 501, with two connecting portions 502 located on either side of the main body 501 and one located in the middle of the main body 501. A baffle rack 518 is provided on the inner side of the connecting portion 502. The baffle rack 518 can be connected to the baffle drive device 105 through gear meshing. The baffle rack 518 has a front end 562 and a rear end 563. The inner side of the connecting portion 502 is curved, meaning that the plane on which the baffle rack 518 lies is also curved. When the baffle rack 518 engages with the gear, causing the baffle 103 to move, the baffle 103 follows an arc-shaped trajectory. Protrusions 541 are provided on either side of the baffle 103. These protrusions 541 are designed to fit into the slideways in the ventilation device's mounting area, defining the motion trajectory of the baffle 103.

[0051] Figure 6 yes Figure 1B A perspective view of the middle baffle driving device 105, as shown in FIG. Figure 6As shown, the baffle drive device 105 includes a baffle motor 601, a motor gear set 604, a connecting rod 605, three connecting rod gears 609, and three baffle drive gears 607. The motor gear set 604, the connecting rod 605, the three connecting rod gears 609, and the three baffle drive gears 607 constitute the baffle transmission component. The motor gear set 604 includes a first gear 613 and a second gear 614. The first gear 613 is fixedly connected to the baffle motor 601 via a shaft 631. The second gear 614 is pivotally connected to the retaining frame 109 and meshes with the first gear 613. Therefore, the baffle motor 601 can rotate by driving the shaft 631, thereby driving the motor gear set 604 to rotate. The three connecting rod gears 609 are fixedly connected to the connecting rod 605 and are evenly distributed along the length of the connecting rod 605, with one connecting rod gear located in the middle of the connecting rod 605. The second gear 614 meshes with the connecting rod gear 609 located in the middle, so that the rotation of the second gear can drive the connecting rod gear 609 to rotate, thereby driving the connecting rod 605 to move. Each of the three baffle drive gears 607 is pivotally connected to the retaining frame or the panel of the mounting location and meshes with the corresponding connecting rod gear 609, so that the rotation of the connecting rod gear 609 can drive the corresponding baffle drive gear 607 to rotate. The three baffle drive gears 607 respectively mesh with the baffle rack 518, so that the rotation of the three baffle drive gears 607 can drive the baffle 103 to move. In other embodiments, the number and size of the gears in the motor gear set 604 can be set as needed to obtain a suitable rotational speed.

[0052] Figure 7A is a perspective view of the ventilation device in this application when it is installed on the corresponding panel and in the closed position, Figure 7B yes Figure 7A The ventilation device is in the middle position in the three-dimensional diagram, Figure 7B yes Figure 7A A perspective view of the ventilation device in the working position, Figure 8A yes Figure 7A An axial cross-sectional view showing the cross-section of the guide unit rack, Figure 8B yes Figure 7A Another axial section of the baffle rack is shown. Figure 8C yes Figure 7B An axial cross-sectional view showing the cross-section of the guide unit rack, Figure 8D yes Figure 7B Another axial section of the baffle rack is shown. Figure 8E yes Figure 7C An axial cross-sectional view showing the cross-section at the guide unit rack. Figures 7A-8D It is used to illustrate the opening process of the ventilation device 100 .

[0053] like Figures 7A-8C As shown, panel 701 has an elongated air outlet 703. Ventilation device 100 is mounted on the inner side of panel 701, and baffle 103 can be moved to open or close air outlet 703. In some embodiments, the panel forming air outlet 703 and ventilation device 100 are a single integrated component, mounted at a corresponding position on the vehicle's interior panel. In other embodiments, air outlet 703 is formed by the vehicle's interior panel.

[0054] like Figure 7A Figure 8A and 8B As shown, the ventilation device 100 is in the closed position. The baffle 103 is in the closed position, and the air guide unit is in the idle position. In the idle position, the inlet end 301 of the air guide unit 102 is approximately flush with the retaining frame 109, and the outlet end 302 of the air guide unit 102 is spaced a certain distance from the air outlet 703. The air guide unit drive gears 407 and 408 engage with the rear ends 363 of the air guide unit racks 318 and 319, respectively.

[0055] The baffle 103 is approximately the same size as the air outlet 703. When the baffle 103 is closed, it is aligned with the air outlet 703, thereby sealing the air outlet 703. The outer side of the baffle 103 forms a continuous surface with the panel 701. The rear end 563 of the baffle rack 518 engages with the baffle drive gear 607. The inner side of the baffle 103 faces the air guide outlet 252 of the air guide unit 102 and is spaced a certain distance from the air guide outlet 252. In the horizontal direction as shown in the figure, the baffle 103 is at the same height as the air guide unit 102. When viewed from the outer side of the panel 701, the baffle 103 blocks the air guide outlet 252.

[0056] like Figure 7B 、 Figure 8C and 8D As shown, the ventilation device 100 is in the middle position. When the ventilation device needs to be opened, the baffle motor 601 receives a signal to start, driving the baffle drive gear 607 to rotate counterclockwise as shown in the figure, thereby moving the meshing position between the baffle drive gear and the baffle rack 518 of the baffle 103 from the rear end 563 to the front end 562. Because the baffle rack 518 is curved, the baffle 103 rotates counterclockwise and moves into the baffle accommodating portion 285. At this point, the baffle 103 reaches the open position, and the air guide unit 102 remains in the idle position. At this point, viewed from the outside of the panel 701, the air guide unit 102 is located inside the air outlet 703 and is a certain distance away from the air outlet 703.

[0057] like Figure 7C and 8EAs shown, the ventilation device 100 is in the working position. After the baffle 103 reaches the open position, the guide unit motor 401 receives a signal and starts, and the guide motor gear set 403 drives a pair of connecting rod gears 417 and 418 to rotate. The connecting rod gears 417 and 418 drive the guide unit drive gears 407 and 408 to rotate through the connecting rod 405. Figure 8C During the rotation of the air guide unit, the air guide unit drive gears 407 and 408 rotate counterclockwise, and the meshing positions of the air guide unit drive gears 407 and 408 with the air guide unit racks 318 and 319, respectively, move from the rear ends 363 to the front ends 362 of the air guide unit racks 318 and 319. During this process, since the air guide unit drive gears 407 and 408 are connected to the retaining frame 109 via an axis, the air guide unit 102 moves relative to the retaining frame 109 along the extension direction of the air guide unit rack 318 toward the air outlet 703 until the outlet end of the air guide unit 102 contacts the edge of the air outlet 703. At this point, the air guide unit 102 reaches the operating position and, as viewed from the outside of the panel 701, the air guide unit 102 moves outward to the air outlet 703. In the operating position of the air guide unit 102, the outlet end 302 of the air guide unit 102 is in contact with or close to the edge of the air outlet 703, which prevents airflow from entering the gap between the edge of the air outlet 703 and the air guide unit 102. This allows most or all of the airflow to enter the vehicle interior, thereby saving energy. In the operating position of the ventilation device, the air conditioner begins to deliver processed air to the vehicle interior.

[0058] In this embodiment, a pair of guide unit racks 318 and 319 are provided on opposite sides of the guide unit 102, which allows the guide unit 102 to move smoothly and is not easily misplaced or stuck. In other embodiments, only one guide unit rack 318 can also drive the guide unit 102 to move.

[0059] In the ventilation device of the present application, the baffle 103 and the air guide unit 102 are both mounted on the retaining frame 109, but there is no direct contact between the baffle 103 and the air guide unit 102. The baffle 103 and the air guide unit 102 each have a corresponding drive device. During the opening process of the ventilation device 100, the baffle 103 and the air guide unit 102 are driven to move by their respective drive devices, without interfering with each other, thereby avoiding noise generated by friction between the two. The baffle 103 and the air guide unit 102 each have a corresponding drive device, which also makes the baffle 103 and the air guide unit 102 easier to disassemble and repair. When one component fails, only the corresponding component needs to be replaced.

[0060] During the opening process of the present application, the air guide unit 102 begins to move only when the baffle 103 moves into position. After the baffle 103 opens the air outlet 703, the operator can easily observe the movement of the air guide unit 102 from the air outlet 703 to determine whether the opening process of the ventilation device 100 is complete. The opening process of the ventilation device is continuous and smooth, with a sense of modernity and technology.

[0061] The air outlet device in the present application can be applied to slender strip-shaped air outlets. When a vehicle adopts a long strip-shaped air outlet, that is, when the air outlet is relatively short in the vertical direction, the vertical installation space inside the vehicle is usually relatively small. The ventilation device in the present application can adapt to a smaller installation space. This is because the movement trajectory of the baffle 103 is arc-shaped, which can save space for the ventilation device in the vertical direction. In addition, the guide unit 102 moves in the horizontal direction, and there is no need to reserve space in the vertical direction for the ventilation device 100, so it can be applied to occasions with a smaller installation space in the vertical direction.

[0062] Although only some features of the present application have been illustrated and described herein, various modifications and variations may be made by those skilled in the art. It should be understood that the appended claims are intended to cover all such modifications and variations that fall within the spirit and scope of the present application.
