[0113] The following embodiments of the technical solution of the present application are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present application, and are therefore only used as examples, and cannot be used to limit the scope of protection of the present application.

[0114] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which this application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" in the specification and claims of this application and the above-mentioned figure descriptions and any variations thereof are intended to cover non-exclusive inclusions.

[0115] In the description of the embodiments of the present application, the technical terms "first", "second", etc. are only used to distinguish different objects, and cannot be understood as indicating or implying relative importance or implicitly indicating the number, specific order or primary and secondary relationship of the indicated technical features. In the description of the embodiments of the present application, the meaning of "multiple" is more than two, unless otherwise clearly and specifically defined.

[0116] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0117] In the description of the embodiments of the present application, the term "multiple" refers to more than two (including two). Similarly, "multiple groups" refers to more than two groups (including two groups), and "multiple pieces" refers to more than two pieces (including two pieces).

[0118] There are generally two ways to raise and lower the tail wing of existing vehicles: manual raising and lowering and automatic raising and lowering. When the vehicle speed reaches 110km / h, the tail wing will automatically rise, and when the vehicle stops, the tail wing will automatically retract. If manual raising and lowering is required, just press the button on the side of the gear lever. It should be noted that when the tail wing is automatically raised, it will automatically retract after stopping, but if the tail wing is raised manually, it needs to be retracted manually.

[0119] The raising and lowering of the rear wing is to reduce the air resistance of the vehicle when it is driving at high speed and to improve the stability and safety of the vehicle.

[0120] After the vehicle's rear wing is raised, foreign objects such as leaves may accidentally fall into the receiving groove of the rear wing base. If the foreign objects are not removed in time, the leaves will be sandwiched between the rear wing and the base after the rear wing lands. The leaves will gradually rot and release liquid, causing damage to the paint surface of the rear wing. This situation is particularly prominent in the season of falling leaves. In addition, if the leaves accumulate in places that are not easy to detect, such as the inside of the rear wing lifting mechanism, the leaves will rot after a long time. On the one hand, the rotten leaves will enter the gaps of the rear wing lifting mechanism, affecting the operation and function of the lifting mechanism. On the other hand, the rotten leaves will produce odor, affecting the driving experience.

[0121] The above is only an example of leaves as foreign objects. If the foreign objects are flammable willow fluff, and the willow fluff accumulates in the rear wing hidden box and is not removed in time, in extreme cases, if it encounters sparks, the willow fluff will easily burn the vehicle after burning, which will affect personal safety on the one hand, and cause damage to the vehicle on the other.

[0122] In view of this, the present application provides a tail wing device for a vehicle, comprising a tail wing, a base and a dust blowing mechanism, the base being provided with a receiving groove, and the tail wing being provided with a folded state and a raised state; in the folded state, the tail wing is accommodated in the receiving groove; in the raised state, the tail wing is at least partially exposed from the receiving groove; the dust blowing mechanism is installed on the base and / or the tail wing, and the dust blowing mechanism is used to blow away foreign matter in the receiving groove when the tail wing is in the raised state, so as to reduce or avoid damage to the tail wing caused by the foreign matter.

[0123] According to some embodiments of the present application, referring to Figure 1-Figure 8 The present application provides a tail device, including a tail 1, a base 2 and a dust blowing mechanism 3, wherein the base 2 is provided with a receiving groove 21, and the tail 1 is provided with a stowed state and a raised state. In the stowed state, the tail 1 is received in the receiving groove 21. In the raised state, the tail 1 is at least partially exposed from the receiving groove 21.

[0124] The dust blowing mechanism 3 is installed on the base 2 , and is used to blow away foreign matter in the receiving groove 21 when the tail wing 1 is in a raised state.

[0125] In the technical solution of the embodiment of the present application, when the tail wing 1 is in the raised state, the dust blowing mechanism 3 can be used to blow away foreign matter in the receiving groove 21, thereby reducing or avoiding damage to the tail wing 1 caused by foreign matter.

[0126] In other embodiments, the dust blowing mechanism may also be installed on the tail wing, or the dust blowing mechanism may be installed on the base and the tail wing at the same time. It should be noted that if the dust blowing mechanism is installed on the tail wing, the tail wing will bear a heavy load, which is not conducive to the lifting of the tail wing, and the dust blowing mechanism will affect the air flow of the tail wing, increasing the air resistance of the vehicle when driving at high speed.

[0127] According to some embodiments of the present application, referring to Figure 3 The tail device further includes a detection mechanism 4, which is mounted on the tail 1 and is used to detect whether there is a foreign object in the receiving groove 21 when the tail 1 is in the raised state. The tail 1 can be switched to the retracted state when there is no foreign object in the receiving groove 21.

[0128] The dust blowing mechanism 3 is used to blow away foreign matter when there is foreign matter in the receiving groove 21 .

[0129] In the above scheme, the receiving groove 21 is detected by the detection mechanism 4 to confirm whether there is foreign matter in the receiving groove 21. If there is foreign matter in the receiving groove 21, the foreign matter is blown away by the dust blowing mechanism 3 to reduce the damage caused by the foreign matter to the tail 1. Through the setting of the detection mechanism 4, the dust blowing mechanism 3 can blow away the foreign matter only when there is foreign matter in the receiving groove 21, which can save the air source for blowing away the foreign matter.

[0130] In other embodiments, the detection mechanism may also be installed on the base, or the detection mechanism may be installed on the base and the tail wing at the same time. The specific installation position of the detection mechanism may be selected according to actual needs and is not limited here.

[0131] According to some embodiments of the present application, referring to Figure 2 , Figure 4 , Figure 5 and Figure 7 The dust blowing mechanism 3 includes an air source device 32 and a dust blowing pipeline 31. The dust blowing pipeline 31 is installed on the base 2 and / or the tail wing 1. The dust blowing pipeline 31 is provided with an air inlet end 311 and an air outlet end 312. The air source device 32 is connected to the air inlet end 311. The air source device 32 is used to supply air to the dust blowing pipeline 31 through the air inlet end 311.

[0132] The gas outlet end 312 extends into the containing tank 21 , and is used to allow the gas in the dust blowing pipeline 31 to be blown out into the containing tank 21 , so as to blow away foreign matter.

[0133] The gas source device 32 can be a gas storage tank.

[0134] In the above scheme, when performing the blowing treatment, the air source device 32 can supply air to the dust blowing pipeline 31, and then blow the gas in the dust blowing pipeline 31 into the containing tank 21 through the air outlet end 312, thereby blowing out the foreign matter in the containing tank 21.

[0135] According to some embodiments of the present application, referring to Figure 2 , Figure 4 and Figure 5 There are two dust blowing pipelines 31, namely, a first pipeline 31a and a second pipeline 31b, wherein the first pipeline 31a is located at the front side of the base 2, and the second pipeline 31b is located at the rear side of the base 2. Further, the air inlet end 311 of the first pipeline 31a and the air inlet end 311 of the second pipeline 31b are connected to the front side of the base 2 and can be connected to the air source device 32, the air outlet end 312 of the first pipeline 31a faces the front side of the containing tank 21, and the air outlet end 312 of the second pipeline 31b faces the rear side of the containing tank 21.

[0136] By providing two dust blowing pipes 31 , foreign matters can be blown away from the front and rear sides of the containing tank 21 at the same time, so that the efficiency of blowing away foreign matters is better and the blowing away effect is better.

[0137] In other embodiments, the dust blowing pipelines may also be provided with other numbers, such as 1, 3 or 5, etc., which are not limited here, and it is only necessary that the dust blowing mechanism can realize the blowing away of foreign matter.

[0138] According to some embodiments of the present application, referring to Figure 2 There are multiple air inlet ends 311, and the multiple air inlet ends 311 are spaced apart from each other.

[0139] When only one air source device 32 is provided, each air inlet end 311 is communicated with the single air source device 32 .

[0140] When there are multiple air source devices 32, it is necessary to ensure that each air source device 32 is connected to at least one air inlet end 311, so that each air source device 32 can supply air to the dust blowing pipeline. At this time, each air inlet end 311 can be connected to only one air source device 32, or can be connected to multiple air source devices 32 at the same time, which is not limited here.

[0141] According to some embodiments of the present application, referring to Figure 4 and Figure 5 There are multiple air outlet ends 312, and the multiple air outlet ends 312 are arranged at intervals along the left and right directions of the base 2.

[0142] In the above solution, the multiple air outlet ends 312 can cooperate with each other, so that the total air blowing area of ​​the dust blowing mechanism 3 is larger, and foreign matter inside the entire containing tank 21 can be better blown away.

[0143] According to some embodiments of the present application, referring to Figure 2-Figure 4 The gas outlet end 312 is provided with a one-way valve 5, and the one-way valve 5 is used to blow the gas in the dust blowing pipeline 31 into the containing tank 21 in one direction.

[0144] In the above scheme, by setting the one-way valve 5, the gas in the dust blowing pipeline 31 can be blown out to the containing tank 21 in one direction. At the same time, it can prevent foreign matter from entering the dust blowing pipeline 31 and the air source device 32 from the air outlet end 312 when no blowing is performed, so as to avoid damaging the dust blowing pipeline 31 and the air source device 32.

[0145] According to some embodiments of the present application, referring to Figure 6 The one-way valve 5 includes a first fixing member 51, a second fixing member 52, a valve core 53 and an elastic member 54. The first fixing member 51 and the second fixing member 52 are installed in the air outlet end 312 at intervals along the extension direction of the air outlet end 312. The first fixing member 51 is provided with a first vent hole 511, and the second fixing member 52 is provided with a second vent hole 521. The valve core 53 is provided on a side of the first fixing member 51 close to the second fixing member 52, and the elastic member 54 is elastically supported between the valve core 53 and the second fixing member 52.

[0146] When the gas pressure at the air inlet of the air outlet end 312 is less than or equal to the gas pressure at the air outlet of the air outlet end 312, the valve core 53 abuts against the first fixing member 51 and blocks the first air hole 511, the first air hole 511 is isolated from the second air hole 521, and the gas in the dust blowing pipeline 31 cannot enter the containing groove 21. At the same time, foreign matter cannot enter the dust blowing pipeline 31 and the air source device 32 from the air outlet end 312, thereby avoiding damage to the dust blowing pipeline 31 and the air source device 32.

[0147] When the gas pressure at the air inlet of the air outlet end 312 is greater than the gas pressure at the air outlet of the air outlet end 312, the valve core 53 moves toward the direction close to the second fixing member 52 and compresses the elastic member 54, the first air hole 511 is connected with the second air hole 521, and the gas in the dust blowing pipeline 31 can enter the containing groove 21 to blow away foreign matter.

[0148] According to some embodiments of the present application, the tail wing device further includes a controller 6 , and the controller 6 is communicatively connected to the detection mechanism 4 .

[0149] The controller 6 is used to detect in real time whether the air source device 32 has air supply conditions when there are foreign objects in the receiving tank 21. The air source device 32 is used to supply air to the dust removal pipeline when the air supply conditions are met, and to stop supplying air to the dust removal pipeline when the air supply conditions are not met.

[0150] The tail wing 1 can also be switched to the retracted state when the air source device 32 does not have the air supply condition.

[0151] In the above scheme, the controller 6 detects whether the air source device 32 has the air supply conditions, so that the air source device 32 supplies air to the dust removal pipeline only when the air supply conditions are met to blow away foreign matter. If the air source device 32 does not have the air supply conditions, the tail wing 1 can be switched to the retracted state first, and then the foreign matter can be removed manually.

[0152] According to some embodiments of the present application, the gas supply condition may include a preset gas pressure threshold.

[0153] The controller 6 is used to detect the current air pressure of the air source device 32 when there is a foreign object in the receiving groove 21. When the current air pressure is greater than or equal to the air pressure threshold, the air source device 32 is in a condition to supply air. When the current air pressure is less than the air pressure threshold, the air source device 32 is not in a condition to supply air.

[0154] In the above scheme, the preset air pressure threshold is used as the air supply condition, so that the air source device 32 supplies air to the dust removal pipeline when the corresponding air supply condition is met to blow away foreign matter.

[0155] According to some embodiments of the present application, the gas supply condition may also include a preset first air pressure threshold and a second air pressure threshold, and the first air pressure threshold is greater than the second air pressure threshold.

[0156] The controller 6 is used to detect the initial air pressure of the air source device 32 when there is a foreign object in the receiving groove 21. When the initial air pressure is greater than or equal to the first air pressure threshold, the air source device 32 is in a condition to supply air. When the initial air pressure is less than the first air pressure threshold, the air source device 32 is not in a condition to supply air.

[0157] When the initial air pressure is greater than or equal to the first air pressure threshold, the controller 6 is also used to detect the current air pressure of the air source device 32 in real time when the air source device 32 supplies air to the dust removal pipeline. When the current air pressure is greater than or equal to the second air pressure threshold, the air source device 32 is in a condition to supply air. When the current air pressure is less than the second air pressure threshold, the air source device 32 is not in a condition to supply air.

[0158] In the above scheme, the preset first air pressure threshold and the second air pressure threshold are used as air supply conditions, so that the air source device 32 supplies air to the dust removal pipeline to blow away foreign matter when the corresponding air supply conditions are met.

[0159] According to some embodiments of the present application, when the suspension system of the vehicle is equipped with an air spring, the air source device 32 is an air tank in the air spring.

[0160] In the above scheme, the air source device 32 can use the air tank in the air spring of the vehicle suspension system to improve the integration of the dust blowing mechanism 3 on the vehicle and save the installation space required for setting up an additional air source device. At this time, the air supply conditions need to be set on the premise of meeting the air supply conditions of the air spring in the vehicle suspension system to ensure the normal use of the vehicle suspension system. In other embodiments, the air source device 32 can also use other air tanks independent of the vehicle suspension system.

[0161] According to some embodiments of the present application, referring to Figure 7 There are multiple air source devices 32, and each air source device 32 is connected to the air inlet end 311. At this time, one of the air source devices 32 can be a gas storage tank of an air spring.

[0162] The controller 6 is used to detect the initial air pressure of each air source device 32 when there is a foreign object in the containing tank 21 .

[0163] The air source device 32 whose initial air pressure is greater than or equal to the first air pressure threshold is the target air source device 32, and a plurality of target air source devices 32 are provided. The controller 6 is also used to enable one of the target air source devices 32 to supply air to the dust removal pipeline, and when the current air pressure of the target air source device 32 is less than or equal to the second air pressure threshold, switch another target air source device 32 to supply air to the dust removal pipeline.

[0164] In the above scheme, multiple air source devices 32 can back up each other. When one of the target air source devices 32 fails to supply air, the controller 6 can be used to switch to other target air source devices 32 to achieve continuous air supply to the dust removal pipeline.

[0165] According to some embodiments of the present application, the controller 6 is a controller of a vehicle suspension system or an on-board controller.

[0166] In the above solution, the controller 6 may be a controller of the vehicle suspension system or a vehicle-mounted controller to improve the integration of the rear wing device on the vehicle.

[0167] According to some embodiments of the present application, referring to Figure 7 The tail wing device also includes an air pump 7, the number of the air pumps 7 is consistent with the number of the air source devices 32, and the air pumps 7 and the air source devices 32 are arranged one by one, and the air pumps 7 are used to inflate the corresponding air source devices 32.

[0168] In the above scheme, an air pump 7 is correspondingly provided for each air source device 32, so that the air pump 7 is used to inflate the corresponding air source device 32, thereby increasing the internal air pressure of the corresponding air source device 32, so that the corresponding air source device 32 can always have air supply conditions, or the corresponding air source device 32 can be changed from not having air supply conditions to having air supply conditions.

[0169] According to some embodiments of the present application, referring to Figure 8 The tail wing device also includes a warning mechanism 8, which is communicatively connected to the controller 6.

[0170] The warning mechanism 8 is used to warn the user when there is foreign matter in the containing groove 21 and the gas source device 32 does not meet the gas supply condition.

[0171] Warning mechanism 8 can be selected as a warning light, which can light up when warning the user. Or, warning mechanism 8 can be selected as a voice alarm, which can send a voice alarm when warning the user.

[0172] In the above scheme, the warning mechanism 8 can warn the user when there is foreign matter in the accommodating groove 21 and the air source device 32 does not have the air supply condition, so that the user knows that the current dust blowing mechanism 3 cannot blow away the foreign matter and needs to be manually removed.

[0173] According to some embodiments of the present application, referring to Figure 3 and Figure 8 The detection mechanism 4 includes a shooting module 41 and a recognition module 42 . The shooting module 41 is installed on the tail 1 . The shooting module 41 is communicatively connected to the recognition module 42 . The recognition module 42 is communicatively connected to the controller 6 .

[0174] The photographing module 41 is used to photograph the receiving slot 21 and transmit the photographed image information to the recognition module 42. The recognition module 42 is used to recognize the received image information to confirm whether there is a foreign object in the receiving slot 21.

[0175] In the above solution, the cooperation between the shooting module 41 and the recognition module 42 is used to detect whether there is a foreign object in the receiving groove 21 .

[0176] In other embodiments, the detection mechanism may also be composed of a plurality of sensors, and the plurality of sensors are arranged at intervals at the bottom of the receiving groove. In this case, if one of the sensors senses a foreign object, the foreign object is blown away by the dust blowing mechanism.

[0177] According to some embodiments of the present application, the identification module 42 is integrated into the controller 6 .

[0178] In the above solution, the identification module 42 is integrated into the controller 6 to improve the integration of the tail device and save design space.

[0179] According to some embodiments of the present application, the photographing module 41 photographs the containing slot 21 according to a preset acquisition cycle.

[0180] And / or, the photographing module 41 photographs the receiving slot 21 when the controller 6 receives the instruction to retract the tail wing 1 .

[0181] In the above scheme, when the shooting module 41 shoots according to the preset collection cycle, the detection mechanism 4 can obtain the corresponding foreign object detection data according to the preset collection cycle. When the shooting module 41 shoots when the controller 6 receives the tail 1 folding instruction, the detection mechanism 4 can obtain the foreign object detection data when the controller 6 receives the tail 1 folding instruction.

[0182] According to some embodiments of the present application, referring to Figure 8 The tail wing device also includes a warning mechanism 8, which is communicatively connected with the detection mechanism 4.

[0183] The warning mechanism 8 is used to warn the user when there are still foreign objects in the receiving groove 21 after the dust is blown away by the dust blowing mechanism 3 .

[0184] Warning mechanism 8 can be selected as a warning light, which can light up when warning the user. Or, warning mechanism 8 can be selected as a voice alarm, which can send a voice alarm when warning the user.

[0185] In the above scheme, the warning mechanism 8 can warn the user when there are still foreign objects in the receiving groove 21 after the foreign object blowing process, so that the user knows that the foreign objects are difficult to be blown away by the dust blowing mechanism 3 and need to be removed manually.

[0186] According to some embodiments of the present application, referring to Figure 9-Figure 16 The present application provides a control method for a tail wing device, which is applied to the tail wing device in one or more of the above embodiments, and the method includes:

[0187] Step S1 : when the tail 1 is in the raised state, obtaining first foreign object detection data of the receiving slot 21 , and confirming whether there is a foreign object in the receiving slot 21 according to the first foreign object detection data. The receiving slot 21 is used to receive the tail 1 .

[0188] Step S2: If the first foreign object detection data indicates that there is foreign object in the receiving slot 21, the dust blowing mechanism 3 is controlled to blow away the foreign object from the receiving slot 21. If the first foreign object detection data indicates that there is no foreign object in the receiving slot 21, the tail wing 1 can be folded.

[0189] In the above scheme, since the tail wing device in one or more of the above embodiments can reduce or avoid damage to the tail wing 1 caused by foreign objects, the control method of the tail wing device applied in one or more of the above embodiments can also reduce or avoid damage to the tail wing 1 caused by foreign objects.

[0190] According to some embodiments of the present application, referring to Fig.13 In step S2, the dust blowing mechanism 3 is controlled to blow away foreign matter from the receiving tank 21, which may specifically include the following steps:

[0191] Step S21a, controlling the dust blowing mechanism 3 to blow away foreign matter toward the containing tank 21 according to the target air supply volume, so that the foreign matter can be blown away by the dust blowing mechanism 3.

[0192] Step S21b: acquiring second foreign matter detection data of the containing slot 21 according to a preset first acquisition cycle, and confirming whether the foreign matter in the containing slot 21 has been blown away.

[0193] Step S21c: If the second foreign matter detection data indicates that there is foreign matter in the containing tank 21, and the foreign matter has not been blown away yet, the target air supply volume can be increased, and the foreign matter blowing process can be returned to be executed until the preset stop condition is met, and the foreign matter blowing process is stopped.

[0194] The stop condition includes: the second foreign matter detection data indicates that there is no foreign matter in the containing groove 21, or the execution times of the foreign matter blowing process reaches a preset times threshold, or the execution time of the foreign matter blowing process reaches a preset time threshold.

[0195] Specifically, if the second foreign matter detection data indicates that there is no foreign matter in the receiving groove 21 , it means that the foreign matter in the receiving groove 21 has been blown away. At this time, the tail wing 1 can be folded after the foreign matter blowing process is stopped.

[0196] If the second foreign matter detection data indicates that there are still foreign matters in the receiving slot 21, "the number of executions of the foreign matter blowing process reaches the preset number threshold" can be selected as the stop condition. At this time, the foreign matter blowing process adopts intermittent multiple blowing. The preset number threshold of the foreign matter blowing process can be set to 3 times or 5 times, etc., which can be set according to actual needs and is not limited. The execution time of a single foreign matter blowing process can be set to 2 seconds or 4 seconds, etc., which can be set according to actual needs and is not limited.

[0197] If the second foreign matter detection data indicates that there are still foreign matters in the containing groove 21, "the execution time of the foreign matter blowing away treatment reaches the preset time threshold" can also be selected as the stop condition. At this time, the foreign matter blowing away treatment adopts a continuous single blowing away method, that is, the continuous blowing away is performed for a preset time length (that is, the time threshold). The preset time threshold of the foreign matter blowing away treatment refers to the total execution time of a single foreign matter blowing away treatment. The preset time threshold of the foreign matter blowing away treatment can be set to 6 seconds or 8 seconds, etc., and can be set according to actual needs, and there is no restriction on this.

[0198] In the above scheme, during the foreign body blowing process, the second foreign body detection data of the receiving slot 21 is obtained according to the preset first acquisition cycle to confirm whether the foreign body has been blown away. After the preset stop condition is met, the foreign body blowing process is stopped to complete the entire foreign body blowing process.

[0199] According to some embodiments of the present application, referring to Fig.11In step S1, when the tail 1 is in the raised state, obtaining the first foreign object detection data of the receiving slot 21 may include the following steps:

[0200] S11 . When the tail 1 is in a raised state, first foreign object detection data of the receiving slot 21 is acquired according to a preset second acquisition cycle.

[0201] In the above solution, the receiving slot 21 can be detected when the tail 1 is in the raised state according to the preset second collection period, so as to obtain the first foreign object detection data of the receiving slot 21.

[0202] According to some embodiments of the present application, referring to Fig.12 In step S1, when the tail 1 is in the raised state, obtaining the first foreign object detection data of the receiving slot 21 may also include the steps of:

[0203] S12 , when the tail 1 is in the raised state, in response to a command to retract the tail 1 , obtaining first foreign object detection data of the receiving slot 21 .

[0204] At this time, if the stop condition is met, refer to Fig.16 , the method further comprises:

[0205] S3. If the second foreign object detection data acquired in the last first collection cycle indicates that there is no foreign object in the receiving slot 21, a command to retract the tail wing 1 is executed.

[0206] If the second foreign object detection data acquired in the last first acquisition cycle indicates that a foreign object exists in the receiving slot 21 , a command to retract the tail wing 1 is executed and foreign object warning information is output.

[0207] In the above scheme, when the tail wing 1 folding instruction is issued, the first foreign object detection data of the receiving slot 21 can be obtained. If the first foreign object detection data indicates the presence of foreign matter, the foreign matter is blown away. Thereafter, the corresponding tail wing 1 folding instruction and foreign matter warning information can be output according to the detected second foreign object detection data.

[0208] According to some embodiments of the present application, the dust blowing mechanism 3 includes an air source device 32 having an air supply switch. Fig.14 In step S2, the dust blowing mechanism 3 is controlled to blow away foreign matter from the receiving tank 21, including:

[0209] S22a, monitoring the current air pressure of the air source device 32.

[0210] S22b, if the current air pressure is greater than or equal to the preset air pressure threshold, control the air supply switch to open, so that the air source device 32 blows air into the containing groove 21 to remove foreign matter.

[0211] S22c: If the current air pressure is less than the air pressure threshold, the air supply switch is controlled to be closed, and the foreign matter removal process is stopped.

[0212] Specifically, the preset air pressure threshold can be a single air pressure threshold. At this time, the current air pressure of the air source device 32 is compared with the preset air pressure threshold. If the current air pressure is greater than or equal to the preset air pressure threshold, the air source device 32 has the air supply conditions, and the air supply switch is turned on to allow the air source device 32 to blow gas into the containing groove 21 to remove foreign matter.

[0213] In addition, the preset air pressure threshold may also include a first air pressure threshold and a second air pressure threshold, and the first air pressure threshold is greater than the second air pressure threshold. At this time, the current air pressure of the air source device 32 (that is, the initial air pressure of the air source device 32 when the foreign matter is detected in the receiving tank 21) is first compared with the first air pressure threshold. If the current air pressure is greater than or equal to the preset air pressure threshold, the air supply switch is turned on so that the air source device 32 blows gas into the receiving tank 21 to perform foreign matter removal processing. During the foreign matter removal process, if the current air pressure of the air source device 32 is less than the second air pressure threshold, the air supply switch is turned off to stop the foreign matter removal process.

[0214] In the above scheme, the current air pressure of the air source device 32 is compared with the preset air pressure threshold. If the air source device 32 meets the air supply conditions, the air supply switch is controlled to open so that the air source device 32 blows gas into the receiving groove 21 to remove foreign matter.

[0215] According to some embodiments of the present application, the gas source device 32 includes multiple gas source devices. Fig.15 In step S2, the dust blowing mechanism 3 is controlled to blow away foreign matter from the receiving tank 21, including:

[0216] S23a, monitoring the current air pressure of the plurality of air source devices 32.

[0217] S23b, determining a target air source device 32 whose current air pressure is greater than the air pressure threshold from the multiple air source devices 32.

[0218] It can be understood that if the preset air pressure threshold includes a first air pressure threshold and a second air pressure threshold, the air source device 32 whose current air pressure is greater than the first air pressure threshold is defined as the target air source device 32 .

[0219] S23c, controlling the gas supply switches corresponding to at least a portion of the target gas source devices 32 to be turned on, so that at least a portion of the target gas source devices 32 blow gas toward the containing groove 21 to perform foreign matter removal processing.

[0220] Here, "at least partly" may include one, some or all of the three situations.

[0221] S23d. During the foreign matter blowing process, if the current air pressure of at least some of the target air source devices 32 is less than the air pressure threshold, control the air supply switches corresponding to at least some of the target air source devices 32 to be closed, and return to the step of determining the target air source device 32 whose current air pressure is greater than the air pressure threshold from multiple air source devices 32 until the preset stop condition is met, and stop the foreign matter blowing process.

[0222] It can be understood that if the preset air pressure threshold includes a first air pressure threshold and a second air pressure threshold at this time, the air supply switch of the air source device 32 whose current air pressure is less than the second air pressure threshold is turned off, and the step of determining the target air source device 32 whose current air pressure is greater than the first air pressure threshold from multiple air source devices 32 is returned to execute.

[0223] In the above scheme, multiple air source devices 32 can back up each other. When one of the target air source devices 32 fails to supply air, it can be switched to other target air source devices 32 to achieve continuous air supply to the dust removal pipeline.

[0224] According to some embodiments of the present application, the present application provides a vehicle, which includes the tail wing device in one or more of the above-mentioned embodiments.

[0225] In the above scheme, since the tail wing device in one or more of the above embodiments can reduce or avoid damage to the tail wing 1 caused by foreign objects, the vehicle including the tail wing device in one or more of the above embodiments can also reduce or avoid damage to the tail wing 1 caused by foreign objects.
