Description

Technical Field

[0001] This disclosure relates to the field of vehicle technology, and in particular to a grille system and control method. Background Technology

[0002] During vehicle operation, the operating status of the vehicle's cooling system is related to the air intake status of the grille. To adapt the grille status to the operating status of the vehicle's cooling system, an active grille shutter (AGS) can be installed. AGS can automatically open or close to adjust the amount of air entering the grille.

[0003] In related technologies, AGS typically turns on or off automatically based on the needs of the vehicle's cooling system.

[0004] However, during driving, if a foreign object obstructs the AGS, the AGS may malfunction, affecting the vehicle's heat dissipation. Summary of the Invention

[0005] In view of this, the present disclosure provides a bar screen system and control method that can automatically clean the blades of the bar screen system and avoid the failure of the bar screen system.

[0006] Specifically, the following technical solutions are included:

[0007] In a first aspect, a grid system is provided, comprising at least one set of blades, a cleaning element, a cleaning element drive structure, and a debris discharge structure;

[0008] The cleaning component drive structure is configured to drive the cleaning component to move along the length direction of the at least one set of blades, and clean the at least one set of blades during the movement;

[0016] The first drive structure is configured to drive the first rotating shaft to rotate, thereby causing the first collecting component to rotate, wherein when the cleaning component moves to the debris collecting position, the rotational movement of the first collecting component can carry away the debris on the cleaning component.

[0017] Optionally, the debris discharge structure further includes a discharge channel, a second drive structure, and a second discharge shaft, wherein the outer wall of the second discharge shaft has a second discharge structure;

[0018] The second discharge shaft is located in the discharge channel, and the second drive structure is used to drive the second discharge shaft to rotate;

[0019] When the first rotating shaft moves to the point that the first collecting member comes into contact with the second discharge structure of the second discharge shaft, the second discharge shaft can carry away the debris on the first rotating shaft and push it into the discharge channel.

[0020] Optionally, the debris discharge structure further includes a third drive structure and a third discharge shaft. The outer wall of the third discharge shaft has a third discharge structure. The extension direction of the third discharge shaft is different from that of the second discharge shaft. The third discharge shaft is located within the discharge channel.

[0021] The third drive structure is used to drive the third discharge shaft to rotate, so as to discharge the debris in the discharge channel using the third discharge structure.

[0022] Optionally, the second discharge structure and / or the third discharge structure may be threaded.

[0023] Secondly, a control method for a grille system is provided, the grille system being as described above, the method comprising:

[0024] In response to a bar screen cleaning command, the cleaning component drive structure of the bar screen system is controlled to operate, so as to drive the cleaning component to move along the length direction of the at least one set of blades, and clean the at least one set of blades during the movement;

[0025] The debris discharge structure is controlled to operate so as to collect and discharge debris from the cleaning component.

[0026] This disclosure provides a grille system and control method. The grille system includes a cleaning component and a cleaning component driving structure.

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concepts of this disclosure to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0048] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0049] The directional terms used in the embodiments of this disclosure, such as "upper," "lower," and "side," are generally based on the orientation shown in the figures or the relative orientation between structures when the components in the grille system are conventionally arranged. These directional terms are used merely to more clearly describe the relationships between structures, not to describe absolute orientation. When the components in the grille system are arranged in different postures, the orientation may change; for example, "upper" and "lower" may be interchanged.

[0050] Unless otherwise defined, all technical terms used in the embodiments of this disclosure have the same meaning as commonly understood by one of ordinary skill in the art.

[0051] To make the technical solutions and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0052] In a first aspect, embodiments of this disclosure provide a grille system.

[0053] refer to Figure 1-4 (in Figure 1 This is a top view. Figure 2 and Figure 4 (See side view) The grille system 1 includes at least one set of blades 11, a cleaning element 12, a cleaning element drive structure 13, and a debris discharge structure 14.

[0054] The cleaning component drive structure 13 is configured to drive the cleaning component 12 to move along the length direction of at least one set of blades 11 and clean at least one set of blades 11 during the movement.

[0055] The debris discharge structure 14 is configured to collect and discharge debris from the cleaning component 12.

[0056] This disclosure provides a grille system including a cleaning component and a driving structure for the cleaning component. The driving structure drives the cleaning component to move, enabling it to clean the blades of the grille system and prevent the blades from being blocked or clogged by foreign objects, thereby preventing grille system failure. Furthermore, the grille system also includes a debris discharge structure that collects and discharges debris from the cleaning component. This prevents debris from accumulating in the grille system even in severe weather or harsh environments, ensuring its normal operation. In addition, this grille system can operate automatically, cleaning foreign objects while the vehicle is in motion without requiring manual intervention from the user.

[0057] Optionally, the debris discharge structure 14 can be in two sets, located at opposite ends of the movement trajectory of the cleaning component 12. The cleaning component drive structure 13 drives the cleaning component 12 to move along the length of the blade 11 until it contacts the debris discharge structure at one end (achieving one round of debris collection and discharge), and then moves in the opposite direction until it contacts the debris discharge structure at the other end (achieving another round of debris collection and discharge). In this way, the cleaning component cleans the blade more thoroughly, and the debris discharge structure also cleans the cleaning component itself better. In the following description, only one set of debris discharge structures will be described in detail; the other set of debris discharge structures can be found in the relevant description.

[0058] In some embodiments, reference Figure 1-2 The grid system 1 also includes a track structure 15, which is configured to define the movement trajectory of the cleaning element 12 as parallel to the length direction of the blade 11.

[0059] Based on the above design, it can be ensured that the cleaning component always moves parallel to the length of the blade, enabling a more thorough cleaning of the blade along its length and preventing localized dirt residue. The track structure also prevents the cleaning component from derailing, ensuring stable operation.

[0060] Optionally, the track structure 15 and the cleaning component 12 can be positioned in front of the blade 11 to improve the space utilization efficiency of the front of the vehicle. Here, "front" refers to the vehicle itself, with the closer to the front of the vehicle being considered "front" and the closer to the rear being considered "rear".

[0061] Optional, see reference Figure 4 The track structure 15 can be a groove structure extending along the length of the blade, and is respectively arranged at both ends of the cleaning component to define the movement trajectory at both ends of the cleaning component. In this way, the cleaning component can be made more stable.

[0062] In some embodiments, reference Figure 4 The cleaning component drive structure 13 is also configured to drive the cleaning component 12 to rotate during its movement along the length of the blade 11.

[0063] Based on the above configuration, the cleaning component can not only scrape foreign objects off the blade surface, but also improve the scraping efficiency through rotational motion.

[0064] In some embodiments, reference Figure 4 The cleaning component 12 is a brush. Using a brush as a cleaning component helps reduce costs and improves the efficiency of removing foreign objects.

[0065] In another embodiment, the cleaning component can also be implemented by wrapping a cleaning cloth around the central shaft, or the cleaning component can be a scraper, etc. The implementation of the cleaning component is highly flexible; the above are just examples and can be adjusted according to requirements.

[0066] Optionally, the cleaning component drive structure 13 is a cleaning component drive motor. In this way, the energy output by the cleaning component drive motor can drive the cleaning component to move more efficiently.

[0067] Optional, see reference Figure 4 When the cleaning component drive structure 13 is a motor, the cleaning component drive structure 13 can be located at least partially within the track structure 15 and installed at one end of the cleaning component 12, and the cleaning component drive structure 13 moves synchronously with the cleaning component 12 along the blade length direction. In this way, the track structure indirectly limits the movement trajectory of the cleaning component by limiting the movement trajectory of the cleaning component drive structure.

[0068] It should be noted that the movement of the cleaning component along the blade length and its own rotation can both be achieved using the aforementioned cleaning component drive structure. In specific implementations, the cleaning component drive structure may include a reducer or differential, etc., to transmit kinetic energy in different directions and with different torques, thereby driving the movement of the cleaning component along the blade length and the rotation of the cleaning component itself, respectively. The above implementation methods can be found in related technologies, and will not be described in detail here.

[0069] In other embodiments, the cleaning component drive structure can also be a gear-transmission belt mating structure, that is, the gear transmits the output energy of the drive structure to the transmission belt, and the transmission belt drives the cleaning component to move, in which case the end of the cleaning component is at least partially located in the track structure.

[0070] In some embodiments, the cleaning element 12 extends perpendicular to the length direction of the blade 11; there are two cleaning element drive structures 13, located at both ends of the cleaning element 12.

[0071] Based on the above configuration, on the one hand, the cleaning efficiency of the cleaning components can be improved by utilizing two cleaning component drive structures. On the other hand, the two cleaning component drive structures can cooperate collaboratively. For example, one cleaning component drive structure can be used as the primary drive structure, and the other as an emergency drive structure. When the primary drive structure fails, the emergency drive structure can be activated to replace the failed drive structure. In this way, the resistance of the cleaning component drive structure of the bar screen system to unexpected accidents can be improved.

[0072] In some embodiments, reference Figure 2-3 The debris discharge structure 14 includes a first drive structure 141, a first rotating shaft 142 and a first collection member 143. The first collection member 143 is located on the first rotating shaft 142 and extends outward along the radial direction of the first rotating shaft 142.

[0073] The first drive structure 141 is configured to drive the first rotating shaft 142 to rotate, thereby causing the first collecting member 143 to rotate. When the cleaning member 12 moves to the debris collecting position, the rotational motion of the first collecting member 143 can carry away the debris on the cleaning member 12.

[0074] In this embodiment, as the cleaning component moves along the length of the blade until it reaches the debris collection position, the first collecting component on the first rotating shaft can carry away the debris on the cleaning component, thus collecting the debris and preventing the cleaning component from being trapped by debris and reducing its cleaning power. It should be noted that the aforementioned "debris collection position" can refer to the position of one end of the blade. At this position, there can be no interference between the cleaning component and the blade, but there is interference between the cleaning component and the first collecting component (specifically, for example, the first collecting component is inserted into the gap between the bristles of the brush and carries away the debris in the gap between the bristles through rotational movement).

[0075] Optional, see reference Figure 2There can be two first drive structures 141, respectively arranged at both ends of the first rotating shaft 142, to drive the first rotating shaft 142 in a coordinated manner. Specifically, both first drive structures 141 can work simultaneously to improve the driving efficiency of the first rotating shaft 142. Alternatively, one first drive structure 141 can serve as the main drive structure, and the other first drive structure can serve as an emergency drive structure, which only works after the main drive structure fails.

[0076] Optional, see reference Figure 2 The first assembly 143 can be columnar, conical, or pyramidal, etc., and can be set according to the requirements.

[0077] In some embodiments, reference Figure 1-2 The debris discharge structure 14 also includes a discharge channel 144, a second drive structure 145, and a second discharge shaft 146. The outer wall of the second discharge shaft 146 has a second discharge structure 1461.

[0078] The second discharge shaft 146 is located in the discharge channel 144, and the second drive structure 145 is used to drive the second discharge shaft 146 to rotate.

[0079] When the first rotating shaft 142 moves to the point that the first collecting member 143 comes into contact with the second discharge structure 1461 of the second discharge shaft 146, the second discharge shaft 146 can carry away the debris on the first rotating shaft 142 and push it into the discharge channel 144.

[0080] In this embodiment, the second drive structure, in conjunction with the second discharge shaft, can carry away and push the debris on the first rotating shaft into the discharge channel, preventing the accumulation of dirt on the first rotating shaft and thus avoiding affecting the subsequent cleaning effect of the first rotating shaft on the cleaning component. Furthermore, pushing the debris into the discharge channel prevents the accumulation of foreign objects in the cleaning path of the cleaning component or the movement path of the blades, thereby preventing any impact on the normal operation of the cleaning component and the normal opening and closing of the blades.

[0081] Optionally, the extending direction of the second discharge shaft 146 forms an acute angle with the extending direction of the first rotating shaft 142. This way, when the second discharge shaft pushes debris into the discharge channel using the surface-mounted second discharge structure, the gradually widening space between the second discharge shaft and the first rotating shaft can accommodate accumulated debris, ensuring that the cleaning effect of the second discharge shaft on the first rotating shaft does not significantly decrease in a short period. Simultaneously, the acute angle also ensures that the second discharge shaft can have a larger contact area with the first collection component on the first rotating shaft, thereby ensuring effective cleaning of the first collection component at different locations on the first rotating shaft. Optionally, the aforementioned acute angle is between 15 and 45 degrees.

[0082] Optionally, the discharge channel 144 may be composed of curved surfaces. The discharge channel 144 may be a fully enclosed channel, or a channel consisting only of partial curved baffles (e.g., roughly enclosed by an upper baffle and a lower baffle). The specific shape can be adjusted according to the available space in the vehicle.

[0083] Optionally, the discharge channel 144 can be connected to the external environment of the vehicle, so that the collected debris can be discharged directly outside the vehicle through the discharge channel 144.

[0084] Optional, see reference Figure 2 The first collection component 143 includes a long collection component 1431 and a short collection component 1432. The two collection components of different lengths allow for the effective removal of debris of different shapes and sizes.

[0085] Optional, see reference Figure 2 The number of long aggregate components 1431 can be multiple, and they are distributed along the length direction of the first rotating axis; the number of short aggregate components 1432 can also be multiple, and they are distributed along the length direction of the first rotating axis. That is, both long aggregate components 1431 and short aggregate components 1432 are arranged in columns. The number of columns for long aggregate components 1431 can be one or more, and the number of columns for short aggregate components 1432 can be one or more, and the specific number of columns can be set according to requirements.

[0086] In some embodiments, reference Figure 2 The debris discharge structure 14 also includes a third drive structure 147 and a third discharge shaft 148. The outer wall of the third discharge shaft 148 has a third discharge structure 1481. The extension direction of the third discharge shaft 148 is different from that of the second discharge shaft 146. The third discharge shaft 148 is located in the discharge channel 144.

[0087] The third drive structure 147 is used to drive the third discharge shaft 148 to rotate so as to discharge debris from the discharge channel 144 using the third discharge structure 1481.

[0088] In this embodiment, the third drive structure cooperates with the third discharge shaft to further assist the second discharge shaft in discharging debris through the discharge channel, preventing debris from accumulating in the discharge channel and thus avoiding failure of the debris discharge structure. Since the third discharge shaft and the second discharge shaft extend in different directions, their cooperation can discharge debris from different locations within the discharge channel, minimizing the possibility of foreign matter residue.

[0089] Optionally, the end of the second discharge shaft 146 can extend toward the third discharge shaft 148 to a target position (at the target position, the end of the second discharge shaft 146 is close to but not in direct contact with the third discharge shaft 148). The third discharge shaft 148 can extend in a direction toward the discharge outlet of the discharge channel 144, where the discharge outlet of the discharge channel 144 refers to its outlet away from the first rotating shaft 142. In this way, the third discharge shaft can efficiently discharge the debris pushed in by the second discharge shaft out of the channel, ensuring that the space in the discharge channel can accommodate the next batch of debris.

[0090] Optionally, the third discharge shaft 148 can be located at the bottom of the discharge channel and parallel to the ground. This ensures that there is not too much residual debris in the discharge channel.

[0091] Optionally, the extension direction of the third discharge shaft 148 forms an obtuse angle with the extension direction of the second discharge shaft 146. In this way, debris at the end of the second discharge shaft can be quickly removed by the third discharge shaft, ensuring that the second discharge shaft is always in a state of high-efficiency operation.

[0092] Optional, see reference Figure 3 The second discharge structure 1461 and / or the third discharge structure 1481 are threaded structures. Using threaded structures to eject foreign objects is a low-cost and stable method. It is important to note that the extension direction of the threaded structure must match the rotation direction of the second or third discharge shaft to achieve the desired ejection effect. For example, a right-hand thread requires a counter-clockwise rotation direction, and a left-hand thread requires a clockwise rotation direction (both clockwise and counter-clockwise directions refer to the rotation direction of the discharge shaft when the user is facing the end of the discharge shaft connected to the drive structure). This is similar to the loosening direction of a screw; please refer to relevant technical specifications for details.

[0093] Optional, see reference Figure 5 The grid system 1 also includes a blade drive structure 17 and a controller 18. The blade drive structure 17 is configured to drive the blade shaft 16 to rotate, thereby driving the blade 11 to move. The controller 18 is configured to control the working state of the blade drive structure 17 so that the grid reaches the required opening degree.

[0094] Optionally, the controller 18 is also configured to control the operating state of the debris discharge structure 14 and the cleaning component drive structure 13. Specifically, the controller 18 is signal-connected to the cleaning component drive structure 13 and is used to issue operating commands to the cleaning component drive structure 13 to start or stop operating. The controller 18 is also signal-connected to the first drive structure 141, the second drive structure 145, and / or the third drive structure 147 of the debris discharge structure 14 to issue commands to these drive structures to control them to start or stop operating.

[0095] Optionally, a pressure switch can be arranged within the track structure 15. When the cleaning component 12 moves along the track structure 15 to the end of the track, the pressure switch sends feedback information to the controller 18. In this way, the controller can more flexibly and accurately control the movement direction of the cleaning component based on the feedback information from the pressure switch.

[0096] Optionally, the controller 18 has a built-in grid cleaning logic, including: responding to a grid cleaning command, controlling the cleaning component drive structure, the first drive structure, the second drive structure, and the third drive structure to operate, so that the cleaning component cleans the blades along the blade length direction. When the cleaning component moves to the end of the track structure, the rotation of the first rotating shaft can drive the first collecting component to carry away and collect debris on the cleaning component. The second and third discharge shafts can push the debris on the first rotating shaft to the discharge channel and discharge it. At this time, the pressure switch at the end of the track structure also sends feedback information to the controller. Responding to the feedback information sent by the pressure switch, controlling the cleaning component drive structure to operate, so that the cleaning component moves in the opposite direction to perform secondary cleaning of the blades. When the cleaning component moves in the opposite direction to the other end of the track structure, the debris discharge structure at the other end of the track structure operates to perform secondary cleaning of the cleaning component (if a debris discharge structure is also provided at the other end). Simultaneously, the pressure switch at the end of the track structure sends feedback information to the controller. Responding to the feedback information sent by the pressure switch, determining that the cleaning component has returned to the default position. The controller controls the operation of the cleaning component drive structure, the first drive structure, the second drive structure, and the third drive structure. It can control these drive structures to start working simultaneously to avoid additional intelligent development costs, or it can control different drive structures to work at different times according to the position of the cleaning component to achieve more intelligent control.

[0097] Optionally, the controller 18 can also pre-store some decision logic, such as cleaning the grille at a specified time, to achieve automated grille cleaning.

[0098] With the help of a controller, the movement of each component in the bar grid system can be controlled individually and precisely, ensuring good coordination among the components and thus improving the working performance of the bar grid system.

[0099] Optionally, the grille system 1 is also connected to the vehicle host 2 via a signal. The vehicle host 2 has a grille cleaning option. When the vehicle host 2 receives an activation command for the grille cleaning option, it sends a grille cleaning command to the grille system 1. The controller 18 of the grille system 1 receives the grille cleaning command and, in response to the grille cleaning command, sends commands to each drive structure in the grille system 1 according to a preset cleaning logic to achieve the aforementioned cleaning process.

[0100] Optionally, the activation command can be triggered in real time by the user or at a timed interval set by the user. Real-time triggering can be initiated by the user interacting with the user interface, based on the grille cleaning options. Timed triggering allows the user to pre-set the grille cleaning time or time interval via the user interface, so that the vehicle's main unit automatically starts the grille cleaning function based on the user settings.

[0101] Optional, see reference Figure 5 The vehicle-mounted main unit 2 is also connected to the camera 3 (such as a vehicle panoramic camera) installed on the periphery of the vehicle. When the vehicle-mounted main unit 2 determines that there is a foreign object blocking the grille at the front of the vehicle based on the image captured by the camera 3, it automatically sends a grille cleaning command to the controller 18 of the grille system 1.

[0102] Optional, see reference Figure 5 The vehicle host 2 is also connected to the radar 4 installed at the front of the vehicle. When the vehicle host 2 determines that there is a foreign object blocking the grille at the front of the vehicle based on the signal of the radar 4, it automatically sends a grille cleaning command to the controller 18 of the grille system 1.

[0103] In practice, the timing of bar grid cleaning can be expanded or adjusted according to needs to achieve intelligent, automated and efficient bar grid cleaning.

[0104] In summary, the grille system provided in this disclosure can actively clean the grille blades, completing the cleaning process while the user is driving, without requiring the user to stop and manually operate it. Furthermore, it achieves intelligent and efficient grille cleaning, ensuring the grille blades are not disturbed by foreign objects for extended periods, effectively preventing grille failure and improving the overall performance of the grille system.

[0105] Secondly, embodiments of this disclosure provide a control method for a grille system, which can be executed by a controller of the grille system. The grille system is as described in the foregoing embodiments.

[0106] refer to Figure 6 This method includes:

[0107] Step 601: In response to the bar screen cleaning command, control the cleaning component drive structure 13 of the bar screen system to operate, so as to drive the cleaning component 12 to move along the length direction of at least one set of blades 11, and clean at least one set of blades 11 during the movement.

[0108] In this step, the grille system controller can receive grille cleaning commands from external sources (such as the vehicle's onboard unit) or generate grille cleaning commands based on its own pre-stored decision logic. In response to the grille cleaning command, the controller can issue commands to the grille system's cleaning component drive structure according to the pre-stored working logic, controlling the operation of the grille system's cleaning component drive structure. The driving logic of the cleaning component drive structure for the cleaning components can be referred to in the aforementioned embodiments and will not be repeated here.

[0109] Step 602: Control the operation of the debris discharge structure 14 to collect and discharge debris from the cleaning component 12.

[0110] In this step, the controller of the grille system can issue commands to each drive structure of the debris discharge structure to activate the structure, collect debris on the cleaning components, and discharge it. The operating logic of each drive structure can be referred to in the previous embodiment and will not be repeated here.

[0111] In summary, the embodiments of this disclosure provide a control method for a grille system. This method enables active cleaning of the grille blades, which can be completed while the user is driving, without requiring manual operation by the user. Furthermore, it achieves intelligent and efficient grille cleaning, ensuring that the grille blades are not disturbed by foreign objects for extended periods, effectively preventing grille failure and improving the performance of the grille system.

[0112] In this disclosure, the terms “first” and “second” are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The term “multiple” means two or more, unless otherwise expressly defined.

[0113] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the disclosure herein. This disclosure is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only.

[0114] It should be understood that this disclosure is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope.
