Description

Technical Field

[0001] The present application relates to the field of air conditioning equipment, and particularly to a defrosting method, device, electronic device and storage medium for a vehicle-mounted air conditioner condenser. Background Art

[0002] A vehicle-mounted air conditioner is one of the necessary devices for modern vehicles, which is used to adjust the temperature and humidity inside the vehicle and provide a comfortable environment for passengers. A vehicle-mounted air conditioner is composed of components such as a compressor, a condenser, a throttling element, an evaporator, and a blower. The working process of a vehicle-mounted air conditioner includes a compression process, a condensation process, a throttling process, and an evaporation process. Among them, the condensation process refers to the process in which high-temperature and high-pressure gaseous refrigerant transfers heat to the air passing through the condenser and liquefies into a liquid. The condensation process takes place in the condenser, and the condenser is also called a heat exchanger, which includes a condensation pipe for the refrigerant to flow through.

[0003] The refrigerant flows into the inlet end of the condensation pipe and flows towards the outlet end. The high-temperature and high-pressure gaseous refrigerant gradually releases heat during the flowing process and transforms from a gaseous state to a liquid state. Since the boiling point of the refrigerant is low and the critical temperature is high, generally, with the assistance of heat dissipation devices such as a blower, when the refrigerant reaches the outlet end, the temperature drops to about 0°C (generally in the range of -1°C to 7°C), resulting in a relatively low temperature at the outlet end of the condensation pipe. When the ambient temperature is too high, the water vapor in the high-temperature air contacts the low-temperature surface at the outlet end of the condenser and releases heat, causing condensation and accumulating into frost. The formation of frost on the condenser will increase the thermal resistance of the condenser and reduce the heat exchange capacity. Therefore, it is necessary to defrost the condenser.

[0004] In the prior art, the main method for defrosting the condenser of a vehicle-mounted air conditioner is to heat the surface of the condenser. The heating methods include using an auxiliary heating device and a reverse cycle heating method to increase the temperature of the condenser surface, so that the frost melts due to heat and the defrosting effect is achieved. Although this method can effectively defrost the condenser of a vehicle-mounted air conditioner, heating the surface of the condenser requires the power device of the vehicle to supply energy. If frequent defrosting is carried out, the energy consumption is relatively large, which will have a greater impact on the endurance of the vehicle.

[0005] Therefore, how to reduce the impact of defrosting on the endurance of the vehicle is a technical problem to be solved urgently. Summary of the Invention

[0060] In the prior art, in the defrosting method for the vehicle-mounted air conditioner condenser, the power device of the vehicle is required for energy supply.

In view of the above problems, the embodiments of the present application provide a defrosting method for the vehicle-mounted air conditioner condenser, which can perform defrosting by using the inertial force generated during the vehicle driving process, reducing the impact of defrosting on the endurance of the vehicle.

[0061] Embodiment 1

[0062] The technical solutions of the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0063] Figure 1 It is a schematic flowchart of the defrosting method for the vehicle-mounted air conditioner condenser shown in the embodiments of the present application.

[0064] This embodiment provides a defrosting method for a vehicle air conditioner condenser, including:

[0065] S1: Detect the acceleration direction of the vehicle and the stationary position of the defrosting wiper respectively, and the defrosting wiper is driven by inertial force;

[0066] Specifically, there is acceleration when the vehicle accelerates or decelerates. In a non-inertial reference frame, when the vehicle accelerates, the acceleration direction is forward, generating a backward inertial force, and when decelerating, the acceleration direction is backward, generating a forward inertial force. The acceleration direction of the vehicle can be detected by an acceleration sensor, or it can be determined by obtaining the current speed in real time and the driver's operations on the accelerator and brake. In addition, the stationary position of the defrosting wiper is obtained by setting a sensor that can obtain position information. The sensor used can be a laser ranging sensor or a non-contact position sensor. The defrosting wiper is used to scrape the frost on the upper surface of the condenser through friction, and its structure is not specifically limited and can refer to the frost scraping structure in the prior art. The defrosting wiper is driven by the inertial force generated when the vehicle accelerates or decelerates, so it is required to be light in mass, so lightweight materials need to be used to reduce the resistance of its own movement to ensure the defrosting efficiency.

[0067] S2: Determine the pre-movement direction of the defrosting wiper according to the acceleration direction and the stationary position of the defrosting wiper;

[0068] In this step, the placement direction of the vehicle air conditioner condenser is the same as the vehicle driving direction, that is, the frosting surface of the condenser is parallel to the straight-line traveling direction of the vehicle. Determine the pre-movement direction of the defrosting wiper according to the acceleration direction and the stationary position of the defrosting wiper. Inertia is the property of an object to resist the change of its motion state. Therefore, the direction of the inertial force is generally opposite to the acceleration direction. Combining the stationary position of the defrosting wiper can determine the direction in which the defrosting wiper is expected to move under the action of the inertial force. For example, when the vehicle accelerates, the direction of the inertial force is backward. If there is space for the defrosting wiper to slide or rotate backward, the pre-movement direction of the defrosting wiper is backward.

[0069] S3: Obtain the frosting area of the condenser and judge the relative position relationship between the pre-movement direction of the defrosting wiper and the frosting area;

[0070] In this step, the frosting position of the vehicle-mounted air conditioner condenser is obtained by setting a sensor that can acquire the frosting area. The sensor can be a multispectral sensor or an infrared thermal sensor. Judging the relative position of the pre-movement direction of the defrosting wiper and the frosting area is to determine whether the defrosting wiper can move to the frosting area under the action of inertia. For example, taking the vehicle forward direction as the abscissa, the direction perpendicular to the vehicle body as the ordinate, and the vehicle forward direction as the positive pole, when the vehicle accelerates forward, the defrosting wiper moves in the negative pole direction under the action of inertia, that is, the pre-movement direction of the defrosting wiper is the negative pole direction. It is judged whether the frosting area is on the forward side of the pre-movement of the defrosting wiper, that is, it is judged whether the coordinate value of the defrosting wiper on the negative pole is less than the coordinate value of the frosting area on the negative pole. It should be noted that because the frosting area is continuous, when judging whether the frosting area is located on the forward side of the pre-movement direction of the defrosting wiper, it is not necessary for the entire frosting area to be on the forward side. As long as there is frost to be scraped on the forward side, it can be determined that the frosting area is located on the forward side of the pre-movement direction of the defrosting wiper.

[0071] S4: If the frosting area is located on the forward side of the pre-movement direction of the defrosting wiper, unlock the defrosting wiper.

[0072] In this step, if the frosting area is located on the forward side of the pre-movement direction of the defrosting wiper, it means that the defrosting wiper can move to the frosting area under the action of inertia, that is, the frosting area can be defrosted. At this time, unlocking the defrosting wiper can achieve the defrosting effect. The way to unlock the defrosting wiper can be mechanical unlocking or electromagnetic unlocking.

[0073] The beneficial effects of this embodiment are:

[0074] In this application, by separately detecting the acceleration direction of the vehicle and the static position of the defrosting wiper, and the defrosting wiper is driven by inertia force, then the pre-movement direction of the defrosting wiper is determined according to the vehicle acceleration direction and the static position of the defrosting wiper. Then, the frosting area of the condenser is obtained, and the relative position relationship between the pre-movement direction of the defrosting wiper and the frosting area is judged, so as to determine whether the defrosting wiper can move to the frosting area under the action of inertia. If the frosting area is located on the forward side of the pre-movement direction of the defrosting wiper, unlock the defrosting wiper, so that the defrosting wiper moves towards the frosting area under the drive of inertia force to achieve defrosting, and use inertia force to provide power for mechanical defrosting, thereby reducing the impact of defrosting on the vehicle's endurance.

[0075] Embodiment 2:

[0076] In actual operation, when the ambient temperature is too low or the humidity is high, thick frost will form on the surface of the vehicle air conditioner condenser. When the frost on the surface of the vehicle air conditioner condenser is too thick, the friction of defrosting may be insufficient, resulting in incomplete defrosting and poor defrosting effect. Therefore, how to effectively frost the surface of the vehicle air conditioner condenser when the frost is thick is a technical problem that needs to be solved urgently.

[0077] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0078] Figure 2 It is another flow chart of the defrosting method of the vehicle air-conditioning condenser shown in the embodiment of the present application.

[0079] In order to solve this technical problem, this embodiment adds the following steps before S4 of the defrosting method for the vehicle air conditioner condenser of the first embodiment:

[0080] S21: obtaining the frosting condition of the vehicle air conditioner condenser;

[0081] In this step, the frosting condition of the surface of the vehicle air conditioner condenser is obtained by setting a sensor that can obtain the frosting condition. The sensor used can be a multi-spectral camera or an infrared thermal sensor. The number of sensors can be one or more. The frosting condition includes frosting thickness and frosting area. Since the frosting condition on the surface of the vehicle air conditioner condenser is not uniform, the frosting condition obtained can be the average value of the frosting condition of all frosted places on the surface of the vehicle air conditioner condenser, or the maximum value of the frosting condition of all frosted places on the surface of the vehicle air conditioner condenser.

[0082] S22: determining a first friction force for defrosting according to the frosting condition;

[0083] In this step, defrosting by the defrost scraper mainly relies on the friction generated by the contact between the defrost scraper and the frost during movement. The frosting condition is positively correlated with the friction required for defrosting. The thickness of the frosting on the vehicle air-conditioning condenser determines the friction required for defrosting. The thicker the frosting, the greater the friction required, and the thinner the frosting, the smaller the friction required. The first friction for defrosting is determined by the frosting condition. The first friction is the friction required to scrape off the current frost at one time, which can be understood as the ideal friction required for defrosting.

[0084] S23: obtaining an absolute value of the acceleration of the vehicle, and adjusting the first friction force according to the absolute value of the acceleration to obtain a second friction force;

[0085] In this step, since the acceleration of the vehicle changes in real time, correspondingly, the inertial force also changes in real time. That is to say, the driving force of the defrosting wiper changes. Because only by ensuring that the defrosting wiper moves through the frosting area and rubs against the frost can the frost be scraped off the surface of the condenser, it is necessary to ensure that the initial driving force A of the defrosting wiper is greater than the sum D of the frosting scraping resistance B and the self-movement resistance C of the defrosting wiper, that is, A > D = B + C. Only in this way can it be ensured that the defrosting wiper enters the moving state from the static state under the drive of the inertial force. C is fixed, while A is variable. Under the condition that the foregoing relational expression holds, there is a maximum value of B corresponding to each specific value of A. Only when the first frictional force is less than the maximum value of B can the foregoing relational expression hold. And A is determined by the acceleration, so it is necessary to adjust the first frictional force according to the absolute value of the acceleration to obtain the second frictional force, ensuring that the second frictional force is less than the maximum value of B and as close as possible to the maximum value of B under possible circumstances, so that the actual frosting scraping resistance conforms to the foregoing relational expression. More specifically, when the first frictional force is less than the maximum value of B, it means that the required frictional force is less than the frictional force that the inertial force can provide, so the first frictional force remains unchanged without adjustment, that is, the second frictional force is equal to the first frictional force. When the first frictional force is greater than the maximum value of B, it means that the required frictional force is greater than the frictional force that the inertial force can provide, so the first frictional force is adjusted to make the second frictional force equal to the maximum value of B. The reason for obtaining the absolute value of the vehicle's acceleration instead of the acceleration is that the acceleration has not only magnitude but also direction. However, since the direction in this embodiment is used to judge the moving direction of the defrosting wiper and has nothing to do with the magnitude of the frictional force, in order to avoid the influence of the positive and negative of the acceleration on the magnitude judgment, the absolute value of the vehicle's acceleration is obtained. The absolute value of the acceleration magnitude is determined by setting a sensor that can obtain the acceleration magnitude or by using the GPS positioning system to obtain the acceleration magnitude of the vehicle. The defrosting wiper is one of the parts of the vehicle and moves together with the vehicle.

[0086] S24: Adjust the distance between the defrosting wiper and the surface of the vehicle-mounted air conditioner condenser according to the second frictional force.

[0087] In this step, when the defrosting wiper moves, the magnitude of the frictional force that the defrosting wiper can generate is positively correlated with the pressure exerted by the defrosting wiper on the frost. The greater the pressure exerted by the defrosting wiper, the greater the defrosting frictional force generated, and the smaller the pressure exerted by the defrosting wiper, the smaller the frictional force generated. And the frictional force exerted by the defrosting wiper is determined by the distance between the defrosting wiper and the surface of the vehicle-mounted air conditioner condenser. The smaller the distance, the greater the frictional force. Therefore, in this step, it is necessary to adjust this distance to ensure that the distance corresponds to the frosting scraping resistance determined in step S23, so as to realize the adjustment of the actual frosting scraping resistance. The adjustment method can be to drive and adjust through a driving device or to adjust through a shape memory alloy.

[0088] It should be noted that since the acceleration of the vehicle changes in real time, the magnitude of the second frictional force also changes in real time. Therefore, the frequency of adjusting the distance between the defrosting wiper and the surface of the vehicle-mounted air conditioner condenser can be various. It can be adjusted once every certain period of time, or it can be adjusted once when the vehicle acceleration change reaches a certain threshold. The specific adjustment frequency depends on the vehicle conditions and the frosting conditions.

[0089] The beneficial effects of this embodiment are as follows:

[0090] In this application, by obtaining the frosting condition of the vehicle-mounted air conditioner condenser, determining the first frictional force for defrosting according to the frosting condition, then obtaining the absolute value of the vehicle's acceleration, and adjusting the first frictional force according to the absolute value of the acceleration to obtain the second frictional force, and then adjusting the distance between the defrosting wiper and the surface of the vehicle-mounted air conditioner condenser according to the second frictional force, that is, according to the frosting condition, providing the maximum frosting scraping frictional force while ensuring that the defrosting wiper can perform defrosting movement, achieving defrosting with the least number of defrosting times and obtaining the best defrosting effect.

[0091] Embodiment III

[0092] In the actual operation process, if the absolute value of the acceleration of the vehicle running is too small, the generated inertial force is not sufficient for defrosting. At this time, unlocking the defrosting wiper cannot achieve the defrosting effect either.

[0093] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0094] Figure 3 It is another schematic flowchart of the defrosting method for the vehicle-mounted air conditioner condenser shown in the embodiments of this application.

[0095] To solve this technical problem, the following steps are added to the defrosting method for the vehicle-mounted air conditioner condenser in Embodiment I and Embodiment II in this embodiment:

[0096] S31: Obtain the absolute value of the vehicle's acceleration;

[0097] In this step, since the acceleration of the vehicle changes in real time, different accelerations of the vehicle can generate different frictional forces. The defrosting frictional force that can be generated is adjusted according to the acceleration of the vehicle to ensure the defrosting effect under different vehicle conditions. The absolute value of the vehicle's acceleration is obtained instead of the acceleration because the acceleration has not only magnitude but also direction. However, since the direction in this embodiment is used to judge the movement direction of the defrosting wiper and has nothing to do with the magnitude of the frictional force, in order to avoid the influence of the positive and negative of the acceleration on the magnitude judgment, the absolute value of the vehicle's acceleration is obtained. The magnitude of the vehicle's acceleration is obtained by setting a sensor that can obtain the acceleration magnitude or using the GPS positioning system. The sensor can be an optoelectronic sensor or a multispectral camera. The absolute value of the acceleration magnitude is calculated based on the magnitude of the vehicle's acceleration.

[0098] S32: When the absolute value of the acceleration is less than or equal to the preset threshold, lock the defrosting wiper.

[0099] In this step, when the absolute value of the acceleration is too small, the inertial force generated by the defrosting wiper is small, resulting in the defrosting wiper being unable to move or the defrosting frictional force that can be generated being small, and the defrosting cannot be effectively carried out. At this time, lock the defrosting wiper. The preset threshold is set according to the vehicle conditions, the mass of the defrosting wiper, and the frosting conditions.

[0100] The beneficial effects produced by this embodiment are as follows:

[0101] In this embodiment, the absolute value of the vehicle's acceleration is obtained, and it is judged whether the absolute value of the vehicle's acceleration is less than or equal to the preset threshold. When the absolute value of the acceleration is less than or equal to the preset threshold, it means that the generated frictional force cannot defrost, and the defrosting wiper is locked so that the defrosting wiper cannot move.

[0102] Embodiment 4

[0103] In the actual operation process, some vehicles have large cooling requirements, such as SUVs, large vehicles, etc. The surface area of the on-vehicle air conditioner condenser of such vehicles is large. Having only one defrosting wiper may cause the defrosting wiper to be far from the frosting area, and it is difficult to mobilize a single defrosting wiper, resulting in the problem that the frost cannot be completely scraped off and the defrosting effect is not good.

[0104] The technical solutions of the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0105] Figure 4 It is another schematic flowchart of the defrosting method for the on-vehicle air conditioner condenser shown in the embodiments of the present application.

[0106] To solve this technical problem, this embodiment further optimizes the defrosting methods of the vehicle air conditioner condensers in Embodiment 1, Embodiment 2, and Embodiment 3. Specifically, the pre-movement direction of the defrosting scraper is set to be parallel to the acceleration direction, that is, the defrosting scraper adopts a sliding defrosting method. At the same time, in order to improve the defrosting efficiency and ensure the defrosting effect, multiple defrosting scrapers are set. Correspondingly, optimizing the detection of the stationary position of the defrosting scraper to: respectively obtain the stationary positions of multiple defrosting scrapers. The multiple defrosting scrapers are arranged in sequence on the surface of the vehicle air conditioner, so that there are similar defrosting scrapers available for each position on the surface of the vehicle air conditioner condenser. Each defrosting scraper can be a defrosting scraper with the same size and shape, or a defrosting scraper with different sizes and shapes. For example, according to different requirements, defrosting scrapers with a larger size and harder brushes can be set in the easily frosted areas. The stationary positions of multiple defrosting scrapers are obtained by setting sensors that can obtain position information. The sensors used can be multi-spectral cameras or infrared thermal sensors. The purpose of obtaining the positions of multiple defrosting scrapers is to facilitate the subsequent mobilization of multiple defrosting scrapers.

[0107] Correspondingly, optimize S3 to: obtain the frosted area of the condenser, and judge the relative position relationship between the corresponding pre-movement direction and the frosted area. The corresponding pre-movement direction is the pre-movement direction of the defrosting scraper closest to the frosted area;

[0108] In this step, the frosted area of the vehicle air conditioner condenser is obtained by setting sensors that can obtain the frosted area. The sensors can be multi-spectral sensors or infrared thermal sensors. The frosted area includes the frosting position and the frosting area. Mobilizing the defrosting scraper closest to the frosted area for defrosting can improve the defrosting efficiency. Therefore, it is necessary to judge the relative position relationship between the pre-movement direction of the defrosting scraper closest to the frosted area and the frosted area.

[0109] It should be noted that since frosting is not only a single point frosting, usually, frosting is in the form of flakes. When the frosting area is large, there may be a situation where the defrosting scraper is located at a position opposite to the middle position of the frosted area. Therefore, there are various judgment methods for the defrosting scraper closest to the frosted area. The closest to the frosted area can be the closest to the geometric center of the frosted area or the closest to the edge of the frosted area. Generally, when the frosted area is small, it is the closest to the edge of the frosted area; when the area of the frosted area is large, it is the closest to the geometric center of the frosted area.

[0110] Correspondingly, optimize S4 to: if the frosted area is located in the forward direction of the corresponding pre-movement direction, unlock the corresponding defrosting scraper.

[0111] In this step, if the frosting area is on the forward side of the frosting scraper closest to the frosting area in the direction of movement, it means that the defrosting scraper closest to the frosting area can move towards the frosting area under the action of inertia to achieve the purpose of defrosting. At this time, unlock the defrosting scraper closest to the frosting area.

[0112] The beneficial effects of this embodiment are as follows:

[0113] In this embodiment, by making the pre-movement direction of the defrosting scraper parallel to the acceleration direction of the vehicle, a plurality of defrosting scrapers can be arranged on the surface of the vehicle-mounted air conditioner condenser. Then, by obtaining the stationary positions of the plurality of defrosting scrapers, and then obtaining the frosting area of the condenser, and judging the relative position between the pre-movement direction of the defrosting scraper closest to the frosting area and the frosting area. When the frosting area is on the forward side of the pre-movement direction of the defrosting scraper closest to the frosting area, unlock the corresponding defrosting scraper to defrost the nearest frosting area. By setting a plurality of defrosting scrapers, each defrosting scraper only defrosts a local area, solving the problem that when the frosting area on the surface of the vehicle-mounted air conditioner condenser is too large, the defrosting effect of a single defrosting scraper is not good, that is, avoiding the problem that when the inertia force is small, the driving distance of the defrosting scraper is short and global defrosting cannot be performed.

[0114] Embodiment Five

[0115] In the actual operation process, when there are a plurality of defrosting scrapers on the surface of the vehicle-mounted air conditioner condenser, under the action of inertia, the plurality of defrosting scrapers tend to concentrate at both ends, resulting in the defrosting scrapers being far from the frosting area in the middle and poor defrosting efficiency.

[0116] The technical solutions of the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0117] Figure 5 It is another flowchart of the defrosting method of the vehicle-mounted air conditioner condenser shown in the embodiments of the present application.

[0118] To solve this technical problem, the following steps are added after S1 in the defrosting method of the vehicle-mounted air conditioner condenser in Embodiment Four in this embodiment:

[0119] S5: Obtain the frosting area of the condenser, and count the frosting area to obtain the high-frequency frosting area;

[0120] In this step, the frosting position of the vehicle-mounted air conditioner condenser is obtained by setting a sensor capable of acquiring the frosting area. The sensor can be a multi-spectral sensor or an infrared thermal sensor. The frosting area includes the frosting area and the frosting position. Since there is more than one frosting area and the frosting areas are different, it is necessary to count multiple frosting areas. There are various counting methods, which can be overlay analysis or clustering analysis, and a high-frequency frosting area is obtained through statistics. The high-frequency frosting area refers to the area with a high frosting frequency, that is, the area where frosting often occurs.

[0121] S6: Adjust the static positions of multiple defrosting scraping members according to the high-frequency frosting area.

[0122] In this step, because the high-frequency frosting area is the area that often needs defrosting, in order to have a defrosting scraping member available for use when the high-frequency frosting area needs defrosting, it is necessary to adjust the static positions of multiple defrosting scraping members according to the high-frequency frosting area, so that the defrosting scraping members are distributed near the high-frequency frosting area. When frosting occurs in the high-frequency frosting area, the defrosting scraping members can defrost in a timely manner under the action of inertia. The way to adjust the defrosting scraping members is to adjust them using inertia.

[0123] Beneficial effects of this embodiment:

[0124] In this embodiment, by obtaining the frosting area of the condenser and counting the frosting area, a high-frequency frosting area is obtained. Subsequently, according to the area and position of the high-frequency frosting area, the static positions of multiple defrosting scraping members are adjusted, and multiple defrosting scraping members are moved to near the high-frequency frosting area to solve the problem that multiple defrosting scraping members converge towards both ends, resulting in the defrosting scraping members being far from the high-frequency frosting area and the defrosting effect being poor.

[0125] Embodiment Six:

[0126] In this embodiment, for the specific application of the defrosting method of the vehicle-mounted air conditioner condenser as described above, this embodiment further provides a defrosting device for the vehicle-mounted air conditioner condenser. By using this defrosting device to implement the defrosting method of the vehicle-mounted air conditioner condenser, the defrosting device for the vehicle-mounted air conditioner condenser in this embodiment includes:

[0127] A defrosting assembly, including a defrosting scraping member driven by inertia. The defrosting assembly is installed on the surface of the vehicle-mounted air conditioner condenser. The defrosting assembly includes a defrosting scraping member, which is driven by inertia and does not require additional energy for driving. The defrosting scraping member can be a defrosting brush or a defrosting blade. The defrosting scraping member defrosts the surface of the vehicle-mounted air conditioner condenser through the generated frictional force, and generally a composite wear-resistant material is selected. In addition, an adjustable spacing mechanism is provided in the defrosting assembly to realize the pressure control between the defrosting scraping member and the condenser surface.

[0128] Preferably, the defrosting assembly further includes a slide rail, a slider, and a locking member; the defrosting scraper is fixedly connected to the slider, and the slider is slidably connected to the slide rail; the moving direction of the slide rail is parallel to the acceleration direction of the vehicle; the locking member is used to lock the slider to the slide rail. The slide rail can be a roller-type slide rail or a ball-type slide rail. The type of the slider matches the slide rail. The slider is slidably connected to the slide rail, and the slider can slide on the slide rail. The defrosting scraper is fixedly connected to the slider. Therefore, the defrosting scraper slides on the slide rail through the slider. The moving direction of the slide rail is the same as the moving direction of the vehicle's acceleration. The defrosting scraper can move on the surface of the vehicle-mounted air-conditioning condenser through the inertial force generated by the vehicle movement. In addition, when there is no frost on the surface of the vehicle-mounted air-conditioning condenser, it is not necessary to start the defrosting scraper for defrosting. At this time, the movement of the defrosting scraper on the slide rail not only cannot defrost, but also has the risk of damaging the vehicle-mounted air-conditioning condenser. Therefore, the defrosting scraper of this embodiment further includes a locking member, which can be a mechanical locking member or an electric control locking member.

[0129] Optionally, the defrosting assembly further includes a pivot shaft and a locking member; the defrosting scraper is rotatably connected to the pivot shaft to form a pendulum suspension structure; the pivot shaft is fixedly connected to the vehicle-mounted air-conditioning condenser; the locking member is used to lock the defrosting scraper to the pivot shaft. The defrosting scraper is rotatably connected to the pivot shaft to form a pendulum suspension structure. The defrosting scraper swings left and right with the pivot shaft as the center point under the action of the inertial force generated by the vehicle movement. In addition, during the falling process of the defrosting scraper swinging left and right, it is also affected by gravity, increasing the acceleration of the defrosting scraper. The pivot shaft is fixedly connected to the vehicle-mounted air-conditioning condenser, and the connection method can be through an angular contact ball bearing; the locking member can be installed inside the pivot shaft. By fixing the defrosting scraper, the defrosting scraper cannot rotate in the pivot shaft, so that the defrosting scraper cannot move under the action of the inertial force. In addition, when there is no frost on the surface of the vehicle-mounted air-conditioning condenser, it is not necessary to start the defrosting scraper for defrosting. At this time, the movement of the defrosting scraper not only cannot defrost, but also has the risk of damaging the vehicle-mounted air-conditioning condenser. Therefore, the defrosting scraper of this embodiment further includes a locking member, which can be a mechanical locking member or an electric control locking member.

[0130] The information acquisition component is used to acquire decision-making information, and the decision-making information includes vehicle movement information, frosting information, and the position information of the defrosting scraper. The information acquisition component includes sensors and a GPS positioning system. According to different application scenarios, different types of sensors are selected. The sensors can be infrared thermal sensors or multispectral cameras. The decision-making information, including vehicle movement information, frosting information, and the position information of the defrosting scraper, is acquired through various types of sensors and the GPS positioning system.

[0131] An information processing component for processing decision-making information and outputting a control strategy according to the processing result. The information processing component includes a graphics processing unit (CPU), an application-specific integrated circuit (ASIC), and a field-programmable gate array (FPGA). The information processing component is used to process decision-making information and output a control strategy according to the processing end. The control strategy includes whether to unlock the defrosting wiper and how to adjust the defrosting wiper, etc.

[0132] A control component for controlling the defrosting component according to the control strategy. Based on the control strategy output by the information processing component, the defrosting component is controlled. For example, if the control strategy is a strategy to unlock the defrosting wiper, the control component controls the defrosting component to be unlocked.
