[0068] 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 a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.
[0069] In related technologies, the front bumper grille of a vehicle needs to provide air intake for the engine and cooling system during driving. The amount of air intake required varies depending on the driving stage and speed of the vehicle. Therefore, the front bumper can be equipped with an active air intake grille. In order to meet aesthetic and other needs, the existing grilles have adopted a gradually opening form. However, the structure of the gradually opening active air intake grille is relatively complex and the cost is high.
[0070] In view of this, this application proposes an air intake grille 100, Figures 1 to 13 This is a schematic diagram of an embodiment of the air intake grille 100 provided in this application. The air intake grille 100 provided in this application can realize the distribution and opening of the grille blades, and has a simple structure, simple movement process, and low cost. The air intake grille 100 will be described in detail below with reference to the main drawings.
[0071] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 This application provides an air intake grille 100, which includes a plurality of grille blades 20 arranged along a first direction, a plurality of motion mechanisms 40 arranged along the first direction, and a power assembly 30. Each motion mechanism drives and connects to a corresponding grille blade 20, and the motion axis of the grille blade 20 intersects the first direction. The power assembly 30 is used to drive the plurality of motion mechanisms 40 to move so that the Nth grille blade 20 and the N+Mth grille blade 20 open in stages. Wherein, N is a positive integer and M is a positive integer greater than or equal to 1.
[0072] In the technical solution of this application, multiple grille blades 20 are arranged along a first direction, and multiple motion mechanisms 40 are arranged along the first direction. Each motion mechanism 40 is driven and connected to a corresponding grille blade 20. A power component 30 is driven and connected to the multiple motion mechanisms 40 to drive the multiple motion mechanisms 40 to move, so that the Nth grille blade 20 and the N+Mth grille blade 20 open in stages. The movement of the grille blades 20 is more automated and technologically advanced, meeting current aesthetic requirements. Compared with existing gradually opening active grilles, the motion mechanism 40 of this application is simple, and the rotation process is simple, thus solving the technical problems of complex structure and high cost of air intake grilles in related technologies. At the same time, by driving the grille blades 20 to rotate through the power component 30, the opening degree of the grille blades 20 can be dynamically adjusted according to actual working conditions, achieving precise control of the air intake volume and meeting the air intake requirements under different working conditions.
[0073] It should be noted that the specific values of N and M are not limited, as long as they can adjust the opening degree of the grille blades 20. In some embodiments, N is 1 and M is 1, that is, the power component 30 drives the first grille blade 20 and the second grille blade 20 to open in stages. In other embodiments, N is 1 and M is 2, that is, the power component 30 drives the first grille blade 20 and the third grille blade 20 to open in stages.
[0074] In some embodiments, the air intake grille 100 further includes a mounting bracket 10, which has an air intake 11, and a plurality of grille blades 20 are mounted on the air intake 11. The plurality of grille blades 20 are used to adjust the opening of the air intake 11, and the motion mechanism 40 and the power component 30 are integrated into the mounting bracket 10.
[0075] In some embodiments, the power assembly 30 can be connected to the vehicle's control system to achieve intelligent adjustment. Specifically, the power assembly 30 drives the motion mechanism 40, which in turn drives the grille blades 20 to rotate. The transmission process is simple, with fewer transmission components and lower cost. For example, both the grille blades 20 and the motion mechanism 40 are arranged along a first direction. The driven wheel 42 of the grooved wheel mechanism 4 is connected to the grille blades 20, and the drive shaft 43 is connected to the drive wheel 41. Multiple grille blades can be controlled without the need for linkages or other structures, resulting in a simple structure and low cost. Furthermore, under low-speed or low-load conditions, the control system can control the power assembly 30, which drives the motion mechanism 40. The motion mechanism 40 reduces the amplitude of the grille blades 20, thus reducing the opening of the grille blades 20 and reducing wind resistance and energy consumption. Under high-speed or high-load conditions, the control system can control the power assembly 30, which drives the motion mechanism 40. The motion mechanism 40 increases the amplitude of the grille blades 20, increasing the opening of the grille blades 20 and improving intake efficiency. This allows for reasonable and dynamic adjustment of the air intake, avoiding unnecessary energy consumption and meeting the different operating conditions of the vehicle.
[0076] It should be noted that the connection method and control method of the control system and power component 30 can refer to the conventional settings in this field, and will not be described in detail here.
[0077] It should be noted that the opening method of the multiple grille blades 20 is not limited, as long as they can be opened in a distributed manner and the size of the air inlet 11 can be adjusted to regulate the air intake volume. For some embodiments, please refer to... Figure 1 , Figure 2 , Figure 3 and Figure 4Multiple grille blades 20 are spaced apart along a first direction (wherein the first direction is the length direction of the mounting frame 10). This rational arrangement of multiple grille blades 20 improves space utilization and ensures airflow uniformity. The power component 30 is configured to sequentially drive each grille blade 20 to rotate, with the rotation start time of each grille blade 20 being sequentially delayed. By sequentially driving each grille blade 20 to rotate with the power component 30, and with the rotation start time of each grille blade 20 being sequentially delayed, a distributed opening and closing effect can be achieved. The delayed start of each grille blade 20 ensures the smoothness and aesthetics of the movement. Furthermore, in this embodiment, the grille blades 20 of the intake grille 100 can gradually and fully open from one end to the other. Relying on a special motion mechanism, a delayed, flowing opening and closing effect of the grille blades 20 can be achieved without adding an additional power component 30. Compared to the gradient active air intake grille 100 in related technologies that relies on different rotation angles, all grille blades 20 in this application can be fully opened, without obstructing the air intake 11, and there is no loss of air intake area. This provides the vehicle with richer dynamic effects while ensuring a larger air intake volume. When the vehicle starts or stops, the flowing grille blades 20 can achieve a better dynamic welcoming effect, enhancing the overall aesthetics and uniqueness of the vehicle.
[0078] For ease of description, the angle between the grille blade 20 and the first direction is used as an example to illustrate the open state of the air intake grille 100. Specifically, when the angle between the grille blade 20 and the first direction is 0 degrees, the air intake grille 100 is in a fully closed state; when the angle between the grille blade 20 and the first direction is greater than 0 and less than 90 degrees, the air intake grille 100 is in an opening state; and when the angle between the grille blade 20 and the first direction is 90 degrees, the air intake grille 100 is in a fully open state.
[0079] Please see Figure 3 , Figure 3 This is the third state of the air intake grille 100. At this time, when the air intake grille 100 is in the closed state, the angle between the multiple air intake grilles 100 and the mounting bracket 10 is 0°. At this time, the air intake 11 is blocked by multiple grille blades 20.
[0080] Please see Figure 4 , Figure 4The air intake grille 100 is in an open state (the open state has various forms, related to the angle between the grille blades 20 and the first direction). In this state, the air intake grille 100 is in a half-open state (the half-open state refers to any state of the air intake grille from the closed state to the open state), with some grille blades 20 open and some grille blades 20 closed. Specifically, when the air intake grille 100 is in the first state, the opening degree of the Nth grille blade 20 is greater than 0, and the opening degree of the (N+1)th grille blade 20 is 0. In this embodiment, taking two adjacent grille blades 20 as an example, the two adjacent grille blades 20 are the first grille blade 20 and the second grille blade 20, respectively. The opening time of the first grille blade 20 is earlier than that of the second grille blade 20. During the opening process of the grille blades 20, the first grille blade 20 begins to rotate, while the second grille blade 20 remains stationary. When the first grille blade 20 rotates to a certain angle, the second grille blade 20 begins to rotate, and so on for the other grille blades 20.
[0081] It should be noted that the above-mentioned angle is not limited and can be 1°, 4°, 5°, 8°, 10°, 15°, 20°, 25°, 30°, etc., and can be set according to the actual situation.
[0082] When the air intake grille 100 is in the open state (the open state can take various forms, depending on the angle between the grille blades 20 and the first direction), the opening degree of both the Nth grille blade 20 and the (N+1)th grille blade 20 is greater than 0, and the opening or closing angle of the Nth grille blade 20 may be the same as or different from the opening degree of the (N+1)th grille blade 20. Please refer to [link / reference]. Figure 5 , Figure 5 This is the second state of the air intake grille 100, in which the air intake grille 100 is fully open, meaning the air intake volume of the air intake grille 100 is at its maximum. Specifically, in this embodiment, taking two adjacent grille blades 20 as an example, the two adjacent grille blades 20 are respectively the first grille blade and the second grille blade. The opening time of the first grille blade is earlier than that of the second grille blade. During the opening process of the grille blade 20, the first grille blade starts to rotate, while the second grille blade remains stationary. When the first grille blade rotates to 90°, the second grille blade rotates to a certain angle. At this time, the first grille blade stops rotating, and the second grille blade continues to rotate until the second grille blade also rotates to 90°. The other grille blades 20 follow the same pattern. When all the grille blades 20 are at 90°, the air intake grille 100 is fully opened.
[0083] It should be noted that the opening method of the multiple air intake grilles 100 is not limited and can be selected according to the actual situation. The air intake grille 100 includes a first blade group 21 and a second blade group 22. The first blade group 21 includes multiple grille blades 20, and the second blade group 22 includes multiple grille blades 20. For ease of description, the opening method of the multiple grille blades 20 in the first blade group 21 and the second blade group 22 are named as follows: the first blade group 21 includes a first sub-blade, a second sub-blade, and a third sub-blade; the second blade group 22 includes a fourth sub-blade, a fifth sub-blade, and a sixth sub-blade.
[0084] In some embodiments, the first blade group 21 and the first blade assembly 21 are arranged sequentially along a first direction, as follows: the air intake grille 100 includes a first sub-blade, a second sub-blade, a third sub-blade, a fourth sub-blade, a fifth sub-blade, and a sixth sub-blade arranged sequentially along the first direction. When the air intake grille 100 has a first air intake volume, as long as some of the grille blades 20 are open, the first sub-blade, the second sub-blade, and the third sub-blade open sequentially, while the fourth sub-blade, the fifth sub-blade, and the sixth sub-blade close; that is, in this embodiment, the multiple grille blades 20 open sequentially.
[0085] In other embodiments, the first blade group 21 and the first blade assembly 21 are arranged sequentially along a first direction, as follows: the air intake grille 100 includes a first sub-blade, a second sub-blade, a third sub-blade, a fourth sub-blade, a fifth sub-blade, and a sixth sub-blade arranged sequentially along the first direction. When the air intake grille 100 has a first air intake volume, as long as some grille blades 20 are open, the first, third, and fifth sub-blades are open, while the second, fourth, and sixth sub-blades are closed. That is, in this embodiment, when multiple grille blades 20 are opened, one grille blade 20 is opened every other grille blade 20.
[0086] In some embodiments, the first blade group 21 and the first blade assembly 22 are arranged sequentially along a first direction, as follows: the air intake grille 100 includes a first sub-blade, a second sub-blade, a third sub-blade, a fourth sub-blade, a fifth sub-blade, and a sixth sub-blade arranged sequentially along the first direction. When the air intake grille 100 has a second air intake volume, the grille blades 20 in both the first blade group 21 and the second blade group 22 are open. That is, the first sub-blade, the second sub-blade, the third sub-blade, the fourth sub-blade, the fifth sub-blade, and the sixth sub-blade are all open.
[0087] It should be noted that the grille blades 20 of the first blade group 21 and the second blade group 22 may be adjacent or not. The arrangement can be determined according to the actual situation. When the grille blades 20 of the first blade group 21 and the second blade group 22 are not adjacent, the arrangement is as follows: the intake grille 100 includes a first sub-blade, a second sub-blade, a third sub-blade, a fourth sub-blade, a fifth sub-blade, and a sixth sub-blade arranged sequentially along the first direction. When the grille blades 20 of the first blade group 21 and the second blade group 22 are adjacent, the arrangement is as follows: the intake grille 100 includes a first sub-blade, a fourth sub-blade, a second sub-blade, a fifth sub-blade, a third sub-blade, and a sixth sub-blade arranged sequentially along the first direction.
[0088] Please see Figure 5 , Figure 6 and Figure 7 The air intake grille 100 also includes a motion mechanism 40, which is connected between multiple grille blades 20 and a power component 30. The motion mechanism 40 links the multiple grille blades 20 together, and a single power component 30 can drive the multiple grille blades 20 to rotate, reducing the number of parts and improving the compactness of the structure.
[0089] Please see Figure 7 and Figure 8 In some embodiments, the motion mechanism 40 includes multiple Geneva mechanisms 4, each Geneva mechanism 4 being drive-connected between the corresponding grille blade 20 and the power assembly 30. Furthermore, the Geneva mechanism 4 is a spatial Geneva mechanism 4. Compared to other Geneva mechanisms 4, the spatial Geneva mechanism 4 can make reasonable use of the three-dimensional space of the air intake grille 100, improving space utilization, reducing the overall volume of the air intake grille 100, and reducing additional transmission structures such as connecting rods.
[0090] Please see Figure 8 , Figure 9 and Figure 10 In some embodiments, each Geneva mechanism 4 includes a driven wheel 42 and a driving wheel 41, which mesh and drive each other. The driven wheel 42 is connected to the grid blades 20, and the driving wheel 41 is connected to the power assembly 30. Specifically, the power assembly 30 drives multiple driving wheels 41 to move, and each driving wheel 41 drives its corresponding driven wheel 42 to rotate, which in turn drives the grid blades 20 to rotate.
[0091] For further information, please refer to [link / reference]. Figure 8 and Figure 9Each Geneva mechanism 4 further includes a first engaging member 411 and a first mating member 421. The first engaging member 411 is disposed on the driving wheel 41; the first mating member 421 is disposed on the driven wheel 42. The first mating member 421 and the first engaging member 411 cooperate so that the driven wheel 42 is driven by the driving wheel 41. In this embodiment, the first engaging member 411 is a engaging post, and the driving wheel 41 is provided with a engaging post. The first mating member 421 is a engaging groove, and the driven wheel 42 is formed with an engaging groove. During the movement of the Geneva mechanism 4, the engaging post can engage in the engaging groove, thereby enabling the driving wheel 41 and the driven wheel 42 to mesh and drive each other. The driving wheel 41 drives the corresponding driven wheel 42 to rotate, and the driven wheel 42 drives the grid blades 20 to rotate. In this embodiment, the driving wheel 41 with a lever and the driven wheel 42 are driven wheels 42 with slots. This structure is more complex but has fewer and more compact components, resulting in higher overall structural stability. In this embodiment, the motion mechanism 40 does not use the traditional multi-link mechanism in related technologies. Relying on the locking effect of the grooved wheel mechanism 4, the grille blades 20 can be self-locked at any angle without relying on the power component 30 to output a large torque to maintain the state of the grille blades 20. This reduces the torque requirement of the power component 30, reduces losses, allows for a wider range of power component selection, and lowers costs. When the vehicle needs to cool the engine and motor, the grille blades 20 can be fully opened to obtain the maximum air intake. During cold starts, the grille blades 20 can be closed to quickly raise the engine temperature. When thermal management needs are met, multiple grille blade opening states can be freely set according to specific circumstances to adjust the air intake, reduce wind resistance, and improve fuel economy and range.
[0092] In related technologies, the rotation of multiple grille blades 20 is achieved through a conventional multi-link active air intake grille 100 motion mechanism. In this embodiment, please refer to... Figure 11 There is a phase difference between the first engaging members 411 of any two adjacent Geneva mechanisms 4 in the first direction. The Geneva mechanism 4 is driven by the engagement of the first engaging member 411 on the driving wheel 41 and the first mating member 421 on the driven wheel 42. By changing the phase difference of the first engaging member 411 on the driving wheel 41 corresponding to different grille blades 20, the rotation time difference of the grille blades 20 can be adjusted. By changing the rotation sequence of the adjustable grille blades 20 in the first direction, and by changing the design of the first mating member 421 on the driven wheel 42 corresponding to each grille blade 20, the angle of the grille blades 20 rotating from the closed state to the open state can be adjusted. By changing the direction of the driving shaft 43 and the grille blades 20, different forms such as vertical, horizontal, and oblique can also be realized. The air intake grille 100 structure of this application can also be arranged in different positions such as the center and sides of the front bumper of the vehicle to match different styling designs.
[0093] Specifically, please refer to Figure 11In any two adjacent Geneva mechanisms 4 in the first direction, the orthographic projection of the first latching member 411 of the Geneva mechanism 4 closer to the power component 30 in the first direction is the first projection, and the orthographic projection of the first latching member 411 of the Geneva mechanism 4 farther from the power component 30 in the first direction is the second projection. The included angle between the first projection and the second projection is α. α can be limited according to the actual situation, for example, it can be 1°, 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, 90° or other unlisted data. With this setting, the first projection and the second projection will definitely not overlap, and the two first latching members 411 in the two adjacent Geneva mechanisms 4 will definitely be at different positions on the drive shaft 43, thereby realizing a phase difference, so that the rotation start time of the multiple grid blades 20 is delayed in sequence, realizing gradual and complete opening from one end to the other end.
[0094] Furthermore, in some embodiments, multiple α values may be equal or unequal. Specifically, among any three adjacent Geneva mechanisms 4 in the first direction, the orthographic projection of the first latching member 411 of the left Geneva mechanism 4 in the first direction is the first projection, the orthographic projection of the first latching member 411 of the middle Geneva mechanism 4 in the first direction is the second projection, and the orthographic projection of the first latching member 411 of the right Geneva mechanism 4 in the first direction is the third projection. The angle between the first projection and the second projection is α1, and the angle between the second projection and the third projection is α2. α1 and α2 may be the same or different, and can be set according to the actual situation.
[0095] Furthermore, in some embodiments, α1 and α2 can be the same, and α1 and α2 are 30°.
[0096] Please see Figure 9 and Figure 10Each grooved wheel mechanism 4 further includes: a limiting member 412, a second mating member 422, and a third mating member 423; the limiting member 412 is located on the driving wheel 41; the second mating member 422 and the third mating member 423 are located on the driven wheel 42, and are situated on both sides of the first engaging member 411; specifically, the limiting member 412 is a limiting post, the second mating member 422 is a closing limiting groove, and the third mating member 423 is an opening limiting groove. When the grille blades of the air intake grille 100 are in the closed or open state, the limiting post couples with the closing limiting groove or the opening limiting groove, thereby restricting the rotation of the driven wheel 42, preventing the grille blades 20 from rotating around the axis under external force, while the limiting post can still rotate freely without affecting the normal movement of the driving shaft 43. When the active shaft 41 rotates, driving the first engaging member 411 and the first mating member 421 to engage, the limiting post rotates from the closed limiting groove to the open limiting groove, coupling the limiting post with the open limiting groove and simultaneously decoupling it from the closed limiting groove. As the active shaft 43 continues to rotate, the engaging post enters the engaging groove from top to bottom, driving the driven wheel 42 to rotate with the active wheel 41 until the limiting post is completely decoupled from the closed limiting groove and simultaneously fully coupled with the open limiting groove again, thus achieving a smooth switching of the grille blade 20 from the closed to the open state. The conversion process of the grille blade 20 from the open to the closed state is the reverse, and can be referred to the above embodiment, which will not be repeated here.
[0097] Please continue reading. Figure 8 , Figure 9 and Figure 10 Each grooved wheel mechanism 4 also includes a clearance part 413, which is located on the driving wheel 41 and is used to clear the driven wheel 42, so that the limiting member 412 can be driven between the second mating member 422 and the third mating member 423. During the movement of the air intake grille 100, the locking post is coupled with the locking groove, and the limiting post needs to be decoupled from the opening limiting groove. As the driving shaft 43 continues to rotate, the locking post enters the locking groove from top to bottom, causing the driving wheel 41 to drive the driven wheel 42 to rotate. At this time, the clearance part 413 can avoid the top of the driven wheel 42, so that the limiting post can move smoothly from the closing limiting groove to the opening limiting groove.
[0098] In some embodiments, the motion mechanism 40 further includes a drive shaft 43, which is mounted on the mounting frame 10 and connected to the power assembly 30; a plurality of drive wheels 41 are drivenly connected to the drive shaft 43. It should be noted that a plurality of driven wheels 42 are integrally formed with the drive shaft 43.
[0099] In some embodiments, please refer to Figure 6 and Figure 9The power assembly 30 also includes a second engaging portion 44 and a second mating portion 45. The second engaging portion 44 is located on the wheel hub mechanism 4 closest to the power assembly 30. The second mating portion 45 is located on the mounting bracket 10. When the multiple grille blades 20 fully open the air inlet 11, the second mating portion 45 engages with the second engaging portion 44 to limit the range of motion of the drive shaft 43.
[0100] Please see Figure 6 In some embodiments, each grid blade 20 has a connecting shaft at both ends arranged opposite each other along the second direction. One end of the connecting shaft is connected to the driven wheel 42, and the other end of the connecting shaft is rotatably mounted on the mounting bracket 10. The connection method between the grid blade 20 and the mounting bracket 10 can refer to conventional settings in the art, and will not be described in detail here.
[0101] Please see Figure 4 and Figure 5 The power components 30 are all located above the grille blades 20 and are concealed by the mounting bracket 10 and the blade mounting plate. When the grille blades 20 are open, the power components 30 are completely invisible, ensuring aesthetics while further increasing air intake. When the grille blades 20 are closed, they overlap each other, forming part of the front bumper, improving the overall appearance of the vehicle and reducing wind resistance. When the grille blades 20 are half-open, the air intake can be freely controlled and adjusted as needed to achieve the best balance between thermal management and wind resistance.
[0102] In some embodiments, the air intake 11 includes at least two opening regions 111, and the multiple grille blades 20 of the two opening regions 111 rotate in opposite directions when opening or closing. Specifically, the air intake grille 100 can achieve a delayed, gradual opening and closing effect from both ends to the middle, and can ultimately achieve maximum air intake by having all grille blades 20 fully open. Since the power component 30 and the motion mechanism 40 are located on the upper part of the grille blades 20, the power component 30 and the motion mechanism 40 are always invisible during the process of the grille blades 20 closing, half-opening, and then fully opening. Coupled with the symmetrically distributed, gradual, flowing motion effect, the welcoming effect and aesthetics of the active air intake grille 100 are greatly improved.
[0103] It should be noted that when the air intake 11 has two opening areas 111, to ensure aesthetics, the mounting bracket 10 includes two mounting sub-frames. The two mounting sub-frames are arranged along the first direction, and an included angle β is formed between the two mounting sub-frames, where β is an obtuse angle. Furthermore, when the angle between the grille blade 20 and the mounting sub-frame is 0 degrees, the air intake grille 100 is in a fully closed state; when the angle between the grille blade 20 and the mounting sub-frame is greater than 0 degrees and less than 85 degrees, the air intake grille 100 is in an open state; and when the angle between the grille blade 20 and the mounting sub-frame is 85 degrees, the air intake grille 100 is in a fully open state.
[0104] It should be noted that there are no restrictions on the specific type and quantity of the power assembly 30; it can be selected according to the actual situation.
[0105] In some embodiments, the plurality of grid blades 20 of the two opening regions 111 are driven by a power assembly 30. Specifically, there are two drive shafts 43, which rotate in opposite directions and are respectively located in the two opening regions 111. Each drive shaft 43 is connected to the plurality of grid blades 20 of the corresponding opening region 111, and the two drive shafts 43 are drively connected to the power assembly 30.
[0106] In one embodiment, the power component 30 is a dual-axis motor connected between two drive shafts 43. The two output shafts of the dual-axis motor rotate in opposite directions, thereby achieving opposite rotation directions when the multiple grille blades 20 of the two opening regions 111 are opened or closed.
[0107] In another embodiment, the power assembly 30 includes a drive motor connected to any one of the drive shafts 43. The two drive shafts 43 are connected by a universal joint, which is used to change the direction of rotation of the two drive shafts 43, thereby realizing that the rotation directions of the multiple grille blades 20 in the two opening areas 111 are opposite when they are opened or closed.
[0108] Please see Figure 6 and Figure 12 In some embodiments, the multiple grille blades 20 of the two opening regions 111 are driven by two power components 30 respectively. Specifically, there are two drive shafts 43, which rotate in opposite directions. The two drive shafts 43 are correspondingly located in the two opening regions 111. Each drive shaft 43 is connected to the multiple grille blades 20 of the corresponding opening region 111, and the two drive shafts 43 are respectively connected to the two power components 30. The two power components 30 drive in opposite directions, thereby realizing that the multiple grille blades 20 of the two opening regions 111 rotate in opposite directions when they are opened or closed.
[0109] Please see Figure 7 The air intake grille 100 also includes at least one transmission mechanism 50, which is drively connected to the plurality of grille blades 20 and the power assembly 30. The transmission mechanism 50 is used to connect the power assembly 30 and the drive shaft 43. The specific configuration of the transmission mechanism 50 can be referred to conventional configurations in the art, and will not be described in detail here. For example, the transmission mechanism 50 can be a spline.
[0110] Please see Figure 13There is a phase difference between the first engaging members 411 of any two adjacent grooved wheel mechanisms 4 in the first direction. This phase difference can be set within a certain angle range without affecting the opening and closing of the grille blades 20. Since the drive shaft 43 is a whole, the phase difference remains unchanged throughout the opening and closing process of the intake grille 100. Figure 13 As shown, ①②③④ are schematic diagrams of different motion stages of the driven wheels 42 of two adjacent Geneva mechanisms 4 during the opening process. The dashed lines represent the position and direction of the drive shaft 43. In the figure, the upper grille blade 20 opens before the lower grille blade 20.
[0111] In the first stage, both the upper driven wheel 42 and the lower driven wheel 42 are in the closed state, and the upper and lower limiting members 412 are coupled with the second mating members 422 of the upper and lower driven wheels 42. The power assembly 30 drives the drive shaft 43 to rotate, and the drive shaft 43 drives the upper drive wheel 41 to rotate. The first locking member 411 on the upper drive wheel 41 first couples with the first mating member 421 of the corresponding upper driven wheel 42, causing the corresponding upper grille blade 20 to start rotating. The upper limiting member 412 is decoupled from the second mating member 422 of the upper driven wheel 42. However, the first mating member 421 of the lower driven wheel 42 has not yet been coupled with the corresponding lower first locking member 411 and remains in the closed state until the first locking member 411 of the lower drive wheel 41 couples with the first mating member 421 of the lower driven wheel 42, thus entering the second stage.
[0112] In the second stage, both the upper and lower grid blades 20 rotate under the drive of the drive shaft 43, and the rotation time difference is fixed by the phase difference control until the third stage is entered.
[0113] In the third stage, the upper grid blade 20 reaches the open position, the first engaging member 411 of the upper driving wheel 41 decouples from the first mating member 421 of the upper driven wheel 42, and the limiting member 412 of the upper driving wheel 41 is coupled with the second mating member 422 of the upper driven wheel 42. During the subsequent movement of the drive shaft 43, the upper grid blade 20 will remain in the open state (i.e., idle) under the action of the second mating member 422. The lower grid blade 20 is still rotating, and the first engaging member 411 of the lower driving wheel 41 and the first mating member 421 of the lower driven wheel 42 control the grid blade 20 to continue rotating until entering the fourth stage.
[0114] In the fourth stage, the lower grille blade 20 also reaches the open position. Like the upper grille blade 20, it will remain open during subsequent movements. The subsequent grille blades 20 will perform this process in sequence until all grille blades 20 reach the open position. At this time, the air intake grille 100 reaches the fully open state.
[0115] The closing process of the air intake grille 100 is the complete reverse of the opening process. The last grille blade 20 to open closes first, and the first grille blade 20 to open closes last, until the air intake grille 100 reaches the closed state.
