DETAILED DESCRIPTION

[0048] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0049] The directional nouns involved in the embodiments of the present disclosure, such as "upper", "lower", "side", etc., are generally based on the relative directional relationship between the structures when the components of the grille system are usually arranged, and these directional nouns are used only to more clearly describe the relationship between the structures, and are not intended to describe absolute directions. When the components of the grille system are placed in different postures, the directions may change, for example, "upper" and "lower" may be interchangeable.

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

[0051] In order to make the technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0052] In a first aspect, an embodiment of the present disclosure provides a grille system.

[0053] refer to Figure 1-4 (in Figure 1 is a top view, Figure 2 and Figure 4 is a side view), the grille system 1 includes at least one set of blades 11, a cleaning member 12, a cleaning member driving structure 13 and a debris discharge structure 14;

[0054] The cleaning member driving structure 13 is configured to drive the cleaning member 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 the debris on the cleaning element 12 .

[0056] The disclosed embodiment provides a grille system, which includes a cleaning member and a cleaning member driving structure. The cleaning member driving structure can drive the cleaning member to move, so that the cleaning member cleans the blades of the grille system to prevent the blades from being blocked or blocked by foreign objects, thereby preventing the grille system from failing. Furthermore, the grille system also includes a debris discharge structure, which can collect and discharge debris on the cleaning member, so that even in bad weather or bad environment, the debris will not accumulate in the grille system and will not affect the normal operation of the grille system. In addition, the grille system can operate automatically to clean foreign objects while the vehicle is moving, without the need for the user to stop the vehicle specifically for manual processing.

[0057] Optionally, the debris discharge structure 14 can be two groups, respectively located at the two ends of the movement trajectory of the cleaning member 12; the cleaning member driving structure 13 is used to drive the cleaning member 12 to move along the length direction of the blade 11 until it contacts the debris discharge structure at one end (to achieve a debris collection and discharge), and then moves in the opposite direction until it contacts the debris discharge structure at the other end (to achieve a debris collection and discharge again). In this way, the cleaning effect of the cleaning member on the blade is more thorough, and the debris discharge structure has a better cleaning effect on the cleaning member itself. In the subsequent description, only one group of debris discharge structures is described in detail, and the other group of debris discharge structures can refer to the relevant description.

[0058] In some embodiments, reference Figure 1-2 The grille system 1 further comprises a track structure 15 , which is configured to limit the movement trajectory of the cleaning member 12 to be parallel to the length direction of the blade 11 .

[0059] Based on the above arrangement, it can be ensured that the cleaning member always moves parallel to the length direction of the blade, and the blade can be cleaned more thoroughly along the length direction of the blade to avoid local dirt residue. The track structure can also prevent the cleaning member from derailing and ensure the stable operation of the cleaning member.

[0060] Optionally, the track structure 15 and the cleaning member 12 can be arranged in front of the blade 11 to improve the space utilization efficiency of the front of the vehicle. The front here is based on the vehicle, closer to the front of the vehicle is the front, and closer to the rear of the vehicle is the rear.

[0061] Optional, reference Figure 4 The track structure 15 can be a groove structure extending along the length direction of the blade, and is arranged at both ends of the cleaning member to define the movement tracks of the two ends of the cleaning member. In this way, the cleaning member can be ensured to be more stable.

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

[0063] Based on the above arrangement, the cleaning member can not only scrape foreign matter on the surface of the blade, but also improve the scraping efficiency by means of the rotational motion.

[0064] In some embodiments, reference Figure 4 The cleaning member 12 is a brush. Using a brush as a cleaning member is beneficial to reducing costs and improving foreign matter removal efficiency.

[0065] In other embodiments, the cleaning member can also be realized by wrapping a cleaning cloth around the central axis, or the cleaning member can be directly a scraping plate, etc. The cleaning member has high flexibility in realization, and the above is only an example, and can be adjusted according to needs.

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

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

[0068] It should be noted that the movement of the cleaning member along the length direction of the blade and the rotational movement of the cleaning member can be achieved by means of the aforementioned cleaning member driving structure. In a specific implementation, the cleaning member driving structure may include a reducer or a differential and other structures to transmit the kinetic energy in different directions and with different torques to drive the movement of the cleaning member along the length direction of the blade and the rotation of the cleaning member itself. The above implementation method can refer to the relevant technology, and this disclosure will not be described in detail.

[0069] In other embodiments, the cleaning element driving structure can also be a gear-belt matching structure, that is, the gear transfers the output energy of the driving structure to the transmission belt, and the transmission belt drives the cleaning element to move, and the end of the cleaning element is at least partially located in the track structure.

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

[0071] Based on the above arrangement, on the one hand, the cleaning efficiency of the cleaning member can be improved by means of the two cleaning member driving structures. On the other hand, the two cleaning member driving structures can be coordinated, for example, one cleaning member driving structure is used as the main driving structure, and the other cleaning member driving structure is used as the emergency driving structure. When the main driving structure fails, the emergency driving structure can be started to replace the failed driving structure. In this way, the resistance of the cleaning member driving structure of the grille system to accidents can be improved.

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

[0073] The first driving structure 141 is configured to drive the first rotating shaft 142 to rotate, so as to drive the first collecting member 143 to rotate, wherein when the cleaning member 12 moves to the debris collecting position, the rotational movement of the first collecting member 143 can take away the debris on the cleaning member 12 .

[0074] In this embodiment, when the cleaning member moves along the length direction of the blade until it reaches the debris collection position, the first collection member on the first rotating shaft can take away the debris on the cleaning member, thereby collecting the debris on the cleaning member and preventing the cleaning member from being entangled by the debris and reducing the cleaning power. It should be noted that the aforementioned "debris collection position" may refer to the position of one end of the blade, at which position there may be no interference between the cleaning member and the blade, and there is interference between the cleaning member and the first collection member (for example, the first collection member is inserted into the gap between the brush filaments of the brush and removes the debris in the gap between the brush filaments through rotation).

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

[0076] Optional, reference Figure 2 The first collecting member 143 is in a columnar, conical or pyramidal shape, etc., and can be specifically configured according to requirements.

[0077] In some embodiments, reference Figure 1-2 The debris discharge structure 14 further includes a discharge channel 144, a second driving structure 145 and a second discharge shaft 146, and 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 driving structure 145 is used to drive the second discharge shaft 146 to rotate;

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

[0080] In this embodiment, the second driving structure cooperates with the second discharge shaft to take away the debris on the first rotating shaft and push it to the discharge channel, so as to avoid the accumulation of dirt on the first rotating shaft, thereby avoiding affecting the subsequent cleaning effect of the first rotating shaft on the cleaning member. In addition, pushing the debris into the discharge channel can avoid the accumulation of foreign matter on the cleaning path of the cleaning member or the movement path of the blades, thereby avoiding affecting the normal operation of the cleaning member and the normal opening and closing of the blades.

[0081] Optionally, the extension direction of the second discharge shaft 146 forms an acute angle with the extension direction of the first rotating shaft 142. In this way, when the second discharge shaft pushes the debris into the discharge channel with the help of the second discharge structure on the surface, the gradually widened space between the second discharge shaft and the first rotating shaft can be used to accommodate the accumulated debris, ensuring that the cleaning effect of the second discharge shaft on the first rotating shaft will not be significantly reduced in a short period of time. At the same time, the acute angle can also ensure that the second discharge shaft can have a large area of ​​contact with the first collection piece on the first rotating shaft, thereby ensuring that the first collection pieces at different positions on the first rotating shaft are effectively cleaned. Optionally, the above-mentioned acute angle is between 45 degrees and 15 degrees.

[0082] Optionally, the discharge channel 144 may be composed of an arc surface. The discharge channel 144 may be a completely enclosed channel, or a channel consisting of only a partial arc-shaped baffle (for example, an upper baffle and a lower baffle). The specific shape may be adjusted according to the available space of the vehicle.

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

[0084] Optional, reference Figure 2 The first collecting piece 143 includes a long collecting piece 1431 and a short collecting piece 1432. Through the collecting pieces of two lengths, debris of different shapes and sizes can be effectively removed.

[0085] Optional, reference Figure 2 , the number of long collection pieces 1431 can be multiple and distributed along the length direction of the first rotating shaft; the number of short collection pieces 1432 can be multiple and distributed along the length direction of the first rotating shaft. That is, the long collection pieces 1431 and the short collection pieces 1432 are arranged in the form of columns. The number of columns of the long collection pieces 1431 can be one or more columns, and the number of columns of the short collection pieces 1432 can be one or more columns, and the specific number of columns can be set according to requirements.

[0086] In some embodiments, reference Figure 2 The debris discharge structure 14 further includes a third driving structure 147 and a third discharge shaft 148. The outer wall of the third discharge shaft 148 has a third discharge structure 1481. The third discharge shaft 148 and the second discharge shaft 146 extend in different directions. The third discharge shaft 148 is located in the discharge channel 144.

[0087] The third driving structure 147 is used to drive the third discharge shaft 148 to rotate, so as to discharge the debris in the discharge channel 144 by utilizing the third discharge structure 1481 .

[0088] In this embodiment, the third drive structure cooperates with the third discharge shaft to further help the second discharge shaft to discharge the debris through the discharge channel, avoiding the accumulation of debris in the discharge channel, thereby preventing the failure of the debris discharge structure. Since the third discharge shaft and the second discharge shaft extend in different directions, the cooperation of the two can discharge all the debris at different positions in the discharge channel, and foreign matter is not likely to remain.

[0089] Optionally, the end of the second discharge shaft 146 can extend to 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), and the third discharge shaft 148 can extend in a direction toward the discharge outlet of the discharge channel 144, wherein 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 by the second discharge shaft to the outside of the channel, ensuring space in the discharge channel to accommodate the next debris.

[0090] Optionally, the third discharge shaft 148 can be located at the bottom of the discharge channel and parallel to the ground. In this way, it can be ensured that there will not be 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, the debris at the end of the second discharge shaft can be quickly removed by the third discharge shaft, so that the second discharge shaft is always in a state of high efficiency.

[0092] Optional, reference Figure 3 , the second discharge structure 1461 and / or the third discharge structure 1481 are threaded structures. The threaded structure is used to push out foreign objects, which is low in cost and has a stable effect. It should be noted that the extension direction of the threaded structure needs to be coordinated with the rotation direction of the second discharge shaft or the third discharge shaft to achieve the effect of pushing out foreign objects. For example, right-handed threads need to be coordinated with the counterclockwise rotation direction, and left-handed threads need to be coordinated with the clockwise rotation direction (the clockwise or counterclockwise direction here refers to the rotation direction of the discharge shaft when the user is facing the end of the discharge shaft connected to the drive structure), which is similar to the loosening direction of the screw, and please refer to the relevant technology for details.

[0093] Optional, reference Figure 5 The grille 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 grille reaches the required opening.

[0094] Optionally, the controller 18 is further configured to control the working state of the debris discharge structure 14 and the cleaning member drive structure 13. Specifically, the controller 18 is connected to the cleaning member drive structure 13 by signal, and is used to issue a work instruction to the cleaning member drive structure 13 so that the cleaning member drive structure 13 starts working or stops working. The controller 18 is 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 by signal, so as to issue instructions to these drive structures to control them to start working or stop working.

[0095] Optionally, a pressure switch may be arranged in the track structure 15, and when the cleaning member 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 member based on the feedback information of the pressure switch.

[0096] Optionally, the controller 18 has a built-in grille cleaning logic, including: in response to the grille cleaning instruction, controlling the cleaning member driving structure, the first driving structure, the second driving structure and the third driving structure to operate so that the cleaning member cleans the blade along the length direction of the blade, wherein when the cleaning member moves to the end of the track structure, the rotational movement of the first rotating shaft can drive the first collecting member to bring down and collect the debris on the cleaning member, and the second discharge shaft and the third discharge shaft can push the debris on the first rotating shaft to the discharge channel and discharge it, and the pressure switch at the end of the track structure will also send feedback information to the controller; in response to the feedback information sent by the pressure switch, controlling the cleaning member driving structure to operate so that the cleaning member moves in the opposite direction to perform a secondary cleaning on the blade, wherein when the cleaning member 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 a secondary cleaning on the cleaning member (when a debris discharge structure is also provided at the other end), and at the same time, the pressure switch at the end of the track structure sends feedback information to the controller; in response to the feedback information sent by the pressure switch, determining that the cleaning member has returned to the default position. Among them, the controller controls the operation of the cleaning element drive structure, the first drive structure, the second drive structure and the third drive structure. These drive structures may be controlled to start working at the same time to avoid additional intelligent development costs, or different drive structures may be controlled to work at different times according to the positions of the cleaning elements to achieve more intelligent control.

[0097] Optionally, some decision logics may be pre-stored in the controller 18, such as cleaning the grille at a specified time, etc., to achieve automatic grille cleaning.

[0098] With the help of the controller, the movement of each component in the grille system can be controlled individually and accurately, ensuring that each component cooperates well, thereby improving the working performance of the grille system.

[0099] Optionally, the grille system 1 is also connected to the vehicle-mounted host 2 by signal. The vehicle-mounted host 2 has a grille cleaning option. When the vehicle-mounted host 2 receives an opening instruction for the grille cleaning option, it sends a grille cleaning instruction to the grille system 1. The controller 18 of the grille system 1 receives the grille cleaning instruction, responds to the grille cleaning instruction, and sends instructions to each driving structure in the grille system 1 according to a preset cleaning logic to implement the aforementioned cleaning process.

[0100] Optionally, the start instruction may be triggered in real time by the user or on a timed basis set by the user. Real-time triggering by the user may include triggering based on the grille cleaning option by the user operating the user interface. The timed triggering set by the user may be a time point or time interval for grille cleaning set by the user in advance with the aid of the user interface, so that the vehicle-mounted host automatically starts the grille cleaning function based on the user setting.

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

[0102] Optional, reference Figure 5 The vehicle-mounted host 2 is also connected to the radar 4 installed at the front end of the vehicle. When the vehicle-mounted 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 instruction to the controller 18 of the grille system 1.

[0103] During implementation, the timing for the grille system to start grille cleaning can be expanded or adjusted as needed to achieve intelligent, automated and efficient grille cleaning.

[0104] In summary, the grille system provided by the embodiment of the present disclosure can realize active cleaning of the grille blades, and the cleaning can be completed while the user is driving, without the need for the user to stop the car for manual operation. In addition, intelligent and efficient grille cleaning can be realized, and the grille blades can be kept from being disturbed by foreign objects for a long time, effectively avoiding the situation of grille failure, and improving the working performance of the grille system.

[0105] In a second aspect, an embodiment of the present disclosure provides 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 above embodiment.

[0106] refer to Figure 6 , the method comprises:

[0107] Step 601: In response to a grille cleaning instruction, control the cleaning member driving structure 13 of the grille system to operate so as to drive the cleaning member 12 to move along the length direction of at least one group of blades 11 and clean at least one group of blades 11 during the movement.

[0108] In this step, the controller of the grille system may receive a grille cleaning instruction from an external device (such as a vehicle-mounted host) or determine and generate a grille cleaning instruction based on its own pre-stored determination logic. The controller may respond to the grille cleaning instruction and issue instructions to the cleaning member driving structure of the grille system according to the pre-stored working logic to control the operation of the cleaning member driving structure of the grille system. The driving logic of the cleaning member driving structure for the cleaning member can refer to the above-mentioned embodiment and will not be repeated here.

[0109] Step 602: Control the debris discharge structure 14 to work, so as to collect and discharge the debris on the cleaning element 12.

[0110] In this step, the controller of the grille system can issue instructions to each driving structure of the debris discharge structure to make the debris discharge structure work, collect and discharge the debris on the cleaning element. The working logic of each driving structure can refer to the above embodiment and will not be repeated here.

[0111] In summary, the disclosed embodiment provides a control method for a grille system, by means of which the grille blades can be actively cleaned while the user is driving, without the need for the user to stop the vehicle for manual operation. Furthermore, intelligent and efficient grille cleaning can be achieved, the grille blades can be kept from being disturbed by foreign objects for a long time, the grille failure can be effectively avoided, and the working performance of the grille system can be improved.

[0112] In the present disclosure, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The term "plurality" refers to two or more, unless explicitly defined otherwise.
