[0002] With the development of science and technology and the improvement of living standards, people are using vehicles more and more frequently, and their requirements for them are also getting higher and higher. In cold environments, frost easily forms on car windows, so vehicles are usually equipped with defrosting systems to remove frost.

[0003] In the prior art, vehicle defrosting systems typically include an air outlet structure, with the air outlet of the air outlet structure located at the bottom of the windshield, through which warm air is output to defrost the windshield.

[0004] However, during their research on existing technologies, the inventors discovered that the air outlet structure, which outputs warm air through the air outlet, can only heat and defrost a small area near the bottom of the windshield, resulting in poor defrosting performance. Summary of the Invention

[0009] When the light transmittance is less than a first preset value, the ambient temperature is obtained;

[0010] When the ambient temperature is lower than a second preset value, the vehicle speed is obtained;

[0011] When the vehicle speed is zero, the first defrosting mode is activated;

[0012] When the vehicle speed is greater than zero, the second defrosting mode is activated;

[0013] In the first defrost mode and the second defrost mode, the defrosting operation performed on the windshield by the first air outlet and the second air outlet corresponds to the preset light transmittance range to which the light transmittance belongs.

[0014] Furthermore, the windshield includes a main area and a sub-area arranged adjacent to each other, and the first air outlet includes a first main air outlet and a first sub-air outlet; the first main air outlet is arranged close to the main area, the first sub-air outlet is arranged close to the sub-area, and the second air outlet includes a second main air outlet located on the side of the main area and a second sub-air outlet located on the side of the sub-area.

[0018] When the light transmittance meets the second preset range, the first main air outlet and the second main air outlet perform a defrosting operation on the main area, and the first auxiliary air outlet performs a defrosting operation on the auxiliary area.

[0019] Optionally, the light transmittance that satisfies the second preset range is greater than the light transmittance that satisfies the first preset range.

[0022] When the light transmittance meets the fourth preset range, the first main air outlet, the second main air outlet, and the first auxiliary air outlet perform a defrosting operation on the main area, and the second auxiliary air outlet performs a defrosting operation on the auxiliary area.

[0023] When the light transmittance meets the fifth preset range, the first main air outlet and the second main air outlet perform a defrosting operation on the main area, and the first auxiliary air outlet and the second auxiliary air outlet perform a defrosting operation on the auxiliary area.

[0024] Optionally, the light transmittance satisfying the fifth preset range is greater than the light transmittance satisfying the fourth preset range; the light transmittance satisfying the fourth preset range is greater than the light transmittance satisfying the third preset range.

[0025] Compared with existing technologies, the defrosting method of the present invention has the following advantages:

[0026] In this embodiment, a windbox is provided on the bottom side of the windshield, the windbox having a first air outlet, and multiple second air outlets are provided on both sides of the windshield. When defrosting the windshield is required, a first defrosting mode is activated when the vehicle speed is zero; a second defrosting mode is activated when the vehicle speed is greater than zero. In both the first and second defrosting modes, the defrosting operation performed on the windshield by the first and second air outlets corresponds to a preset light transmittance range. This allows the appropriate defrosting mode to be determined based on the actual frost condition on the windshield, and enables intelligent air-sweeping defrosting from both the bottom and sides of the windshield, improving defrosting effect and efficiency.

[0027] Another objective of this invention is to provide a defrosting system to solve the problem of poor defrosting performance of vehicles in the prior art.

[0053] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0054] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0055] This application provides a defrosting method that can be used in a vehicle. Specifically, the vehicle may include a windshield, and the defrosting method can be used to perform a defrosting operation on the windshield.

[0056] Reference Figure 1 The diagram shows a structural schematic of a defrosting system for a vehicle according to an embodiment of this application. Figure 1 As shown, a wind box 10 is provided on the bottom side of the windshield 20, the wind box 10 is provided with a first air outlet 11, and multiple second air outlets 12 are provided on both sides of the windshield 20.

[0057] In this embodiment, warm air can be supplied to the bottom side of the windshield 20 through the first air outlet 11 of the bellows 10 for heating. Simultaneously, warm air is supplied to both sides of the windshield 20 through the second air outlets 12 on both sides, expanding the heating area of ​​the windshield 20 and significantly improving defrosting efficiency and effect. Furthermore, in specific applications, warm air can be supplied through the first air outlet 11 and / or the second air outlet 12 to control the specific defrosting area of ​​the windshield 20, avoiding unnecessary energy consumption and contributing to energy conservation and emission reduction.

[0058] like Figure 1As shown, the air box 10 can be equipped with an air guiding mechanism, which allows for independent adjustment of air direction and volume, achieving "sweeping" defrosting and greatly increasing the defrosting area. In practical applications, high-temperature air is mainly defrosted from the "Z" direction of the vehicle through the first air outlet 11 on the air box 10. The second air outlet 12 can be arranged near the A-pillars on both sides of the vehicle, and high-temperature air is mainly defrosted from the "Y" direction of the vehicle through the second air outlet 12. In practical applications, combined with infrared sensor data, the second air outlet 12 can achieve adjustment of air direction and volume. Figure 1 The defrosting system shown can introduce high-temperature air from the heating system into the first air outlet 11 and the second air outlet 12 of the air box 10. Combined with the data from the light transmittance meter, it can achieve the function of rapid defrosting of the windshield.

[0059] Reference Figure 2 The flowchart illustrating the steps of a defrosting method according to an embodiment of this application is shown, as follows: Figure 2 As shown, the defrosting method may specifically include the following steps:

[0060] Step 101: Obtain the light transmittance of the windshield.

[0061] In practical applications, since the light transmittance of the windshield 20 is related to the frost condition of the windshield 20, the more severe the frost condition of the windshield 20, the lower the light transmittance of the windshield 20. Therefore, the light transmittance of the windshield 20 can be used to evaluate the frost condition of the windshield 20.

[0062] In this embodiment of the application, a light transmittance meter can be installed on the windshield 20 to obtain the light transmittance of the windshield 20, and the light transmittance can be used to evaluate the frost condition of the windshield 20.

[0063] Step 102: If the light transmittance is less than the first preset value, obtain the ambient temperature.

[0064] Specifically, if the light transmittance of the windshield 20 is less than a first preset value, the light transmittance of the windshield 20 can be considered poor. In practical applications, the main reasons for poor light transmittance of the windshield 20 are frost formation or dirt accumulation. Therefore, before defrosting the windshield 20, it is necessary to rule out the possibility that dirt accumulation is causing poor light transmittance.

[0065] In this embodiment, a temperature sensor can be installed on the windshield 20 to obtain the ambient temperature of the vehicle. This ambient temperature is then used to determine whether the poor light transmittance of the windshield 20 is due to frost or dirt. Typically, at higher ambient temperatures, poor light transmittance of the windshield 20 is mainly caused by dirt, while at lower ambient temperatures, poor light transmittance is usually caused by frost.

[0066] In practical applications, when the light transmittance of the windshield 20 is greater than or equal to the first preset value, it can be considered that the light transmittance of the windshield 20 is good and does not affect the driver's safe driving. In this case, there is no need to perform defrosting operation on the windshield 20.

[0067] Optionally, the first preset value can be 90%, that is, if the light transmittance of the windshield 20 is less than 90%, it can be considered that the light transmittance of the windshield 20 is poor, and the windshield 20 may have defects such as frost or dirt, and the windshield 20 needs to be defrosted or cleaned.

[0068] It should be noted that, in practical applications, those skilled in the art can set the specific value of the first preset value according to the actual situation. For example, the first preset value can be 80%, 88%, or 95%, etc., and the embodiments of this application do not specifically limit the first preset value.

[0069] Step 103: When the ambient temperature is less than the second preset value, obtain the vehicle speed.

[0070] Specifically, when the ambient temperature is less than the second preset value, it can be considered that the main reason for the poor light transmittance of the windshield 20 is that the windshield 20 is frosted. In this case, it is necessary to perform a defrosting operation on the windshield 20.

[0071] In this embodiment, a vehicle speed detection sensor can be installed on the tires or axle of the vehicle to obtain the vehicle speed. Specifically, after determining that defrosting of the windshield 20 is required based on the ambient temperature, an automatic defrosting mode can be entered. That is, the vehicle speed is further obtained through the vehicle speed sensor to determine whether the vehicle is in a parked or driving state, and different defrosting modes are executed accordingly to further improve defrosting efficiency and effect, while also achieving the goals of energy conservation and emission reduction.

[0072] In practical applications, if the ambient temperature is greater than or equal to the second preset value, it can be considered that the main reason for the poor light transmittance of the windshield 20 is that the windshield 20 is dirty. In this case, the vehicle can remind the user through the instrument panel to activate the wiper system to clean the windshield 20, thereby removing dirt from the surface of the windshield 20, improving the light transmittance of the windshield 20, and thus enhancing the driving safety of the vehicle.

[0073] Optionally, the second preset value is 0 degrees. That is, when the ambient temperature is less than 0 degrees, it can be considered that the main reason for the poor light transmittance of the windshield 20 is frost formation on the windshield 20, requiring defrosting. In practical applications, since 0 degrees is the critical value for icing, frost formation on the windshield 20 is likely to occur below 0 degrees. Therefore, setting the second preset value to 0 degrees is beneficial for accurately evaluating the frost condition of the windshield 20.

[0074] It should be noted that, in practical applications, those skilled in the art can also set the second preset value to other values ​​close to 0 degrees according to the actual situation. For example, the second preset value can be 1 degree, -1 degree, etc., and the embodiments of this application do not specifically limit the second preset value.

[0075] In some optional embodiments of this application, after determining that defrosting operation needs to be performed on the windshield 20 based on the ambient temperature, a manual defrosting mode can also be selected according to the user's choice. That is, based on the user's operation on the dashboard, the first air outlet 11 on the air box 10 and / or the second air outlet 12 on one or both sides of the windshield 20 can be used to perform the defrosting operation to meet the user's personalized requirements.

[0076] Step 104: When the vehicle speed is zero, activate the first defrosting mode.

[0077] In this embodiment, when the vehicle speed is zero, the vehicle can be considered to be in a parked state, meaning the user is not in the vehicle but is performing the defrosting operation remotely. In this case, the first defrosting mode can be used to defrost the windshield 20, balancing defrosting efficiency, defrosting effect, and energy conservation and emission reduction.

[0078] Specifically, in the first defrosting mode, the defrosting operation performed on the windshield 20 by the first air outlet 11 and the second air outlet 12 corresponds to the preset light transmittance range to which the light transmittance belongs, so as to perform the corresponding defrosting operation according to the light transmittance of the windshield 20, so as to achieve the purpose of balancing defrosting efficiency, defrosting effect and energy saving and emission reduction.

[0079] like Figure 1As shown, the windshield 20 may specifically include a main area 201 and a secondary area 202 arranged adjacent to each other, wherein the main area 201 is mainly opposite to the driver's seat, and the secondary area 202 is mainly opposite to the passenger's seat. The first air outlet 11 may specifically include a first main air outlet 111 and a first secondary air outlet 112; the first main air outlet 111 is located near the main area 201, and the first secondary air outlet 112 is located near the secondary area 202. The second air outlet 12 may specifically include a second main air outlet 121 located on the side of the main area 201 and a second secondary air outlet 122 located on the side of the secondary area 202. In the first defrosting mode, the defrosting operation performed by the first main air outlet 111, the first secondary air outlet 112, the second main air outlet 121, and the second secondary air outlet 122 on the main area 201 and / or the secondary area 202 corresponds to the light transmittance, so as to achieve the purpose of balancing defrosting efficiency, defrosting effect, and energy saving and emission reduction.

[0080] Reference Figure 3 The flowchart illustrates the steps of a first defrosting mode according to an embodiment of this application, as shown below. Figure 3 As shown, the first defrosting mode may specifically include the following sub-steps:

[0081] Sub-step 1041: When the light transmittance meets the first preset range, the first main air outlet and the second main air outlet perform a defrosting operation on the main area, and the first auxiliary air outlet and the second auxiliary air outlet perform a defrosting operation on the auxiliary area.

[0082] In this embodiment of the application, when the light transmittance of the windshield 20 meets the first preset range, it can be considered that the light transmittance of the windshield 20 is extremely poor. In order to ensure driving safety, it is necessary to perform a defrosting operation on the windshield 20 as a whole, that is, it is necessary to perform a defrosting operation on the main area 201 and the sub-area 202 of the windshield 20 at the same time.

[0083] Specifically, when defrosting both the main zone 201 and the secondary zone 202 of the windshield 20 simultaneously is required, the first main air outlet 111 and the second main air outlet 121 can be used to defrost the main zone 201, while the first secondary air outlet 112 and the second secondary air outlet 122 can be used to defrost the secondary zone 202. In practical applications, since the first main air outlet 111 is located on the bottom side of the main zone 201 and the second main air outlet 121 is located on the side of the main zone 201, blowing warm air into the main zone 201 through the first main air outlet 111 and the second main air outlet 121 for defrosting can achieve good defrosting effect and efficiency. Similarly, since the first secondary air outlet 112 is located on the bottom side of the secondary zone 202 and the second secondary air outlet 122 is located on the side of the secondary zone 202, blowing warm air into the secondary zone 202 through the first secondary air outlet 112 and the second secondary air outlet 122 for defrosting can achieve a better defrosting effect and efficiency.

[0084] Optionally, the first preset range is greater than 0 and less than 60%. That is, when the light transmittance of the windshield 20 is greater than 0 and less than 60%, the light transmittance of the windshield 20 can be considered to be extremely poor. In order to ensure driving safety, the windshield 20 needs to be defrosted as a whole, that is, both the main area 201 and the sub-area 202 of the windshield 20 need to be defrosted.

[0085] Sub-step 1042: When the light transmittance meets the second preset range, the first main air outlet and the second main air outlet perform a defrosting operation on the main area, and the first auxiliary air outlet performs a defrosting operation on the auxiliary area; wherein, the light transmittance that meets the second preset range is greater than the light transmittance that meets the first preset range.

[0086] In this embodiment of the application, when the light transmittance of the windshield 20 meets the second preset range, it can be considered that the light transmittance of the windshield 20 is generally low. It is necessary to perform defrosting operations on both the main area 201 and the sub-area 202 of the windshield 20 at the same time to ensure driving safety. However, in order to save energy, the defrosting requirements for the sub-area 202 of the windshield 20 can be appropriately reduced.

[0087] Specifically, when the light transmittance of the windshield 20 meets the second preset range, the first main air outlet 111 and the second main air outlet 121 can be used to perform defrosting operation on the main zone 201, which can achieve a better defrosting effect and efficiency. At the same time, the first secondary air outlet 112 is used to perform defrosting operation on the secondary zone 202, and the second secondary air outlet 122 is closed. While defrosting the secondary zone 202, some energy is saved and the generator warm-up time is shortened.

[0088] Optionally, the second preset range is greater than or equal to 60% and less than 90%. That is, when the light transmittance of the windshield 20 is greater than or equal to 60% and less than 90%, it can be considered that the light transmittance of the windshield 20 is generally low. It is necessary to perform defrosting operations on both the main area 201 and the sub-area 202 of the windshield 20 at the same time to ensure driving safety. However, in order to save energy, the defrosting requirements for the sub-area 202 of the windshield 20 can be appropriately reduced.

[0089] Step 105: When the vehicle speed is greater than zero, activate the second defrosting mode.

[0090] In this embodiment, when the vehicle speed is greater than zero, the vehicle is considered to be in a driving state. That is, the user needs to perform a defrosting operation on the windshield 20 while driving the vehicle, and the requirements for defrosting efficiency and effect are relatively high. In particular, the requirements for defrosting effect and efficiency are relatively high for the main area 201 of the windshield 20. At this time, a second defrosting mode can be used to defrost the windshield 20 to balance defrosting efficiency and effect.

[0091] Specifically, in the second defrosting mode, the defrosting operation performed on the windshield 20 by the first air outlet 11 and the second air outlet 12 corresponds to the preset light transmittance range to which the light transmittance belongs, so as to perform the corresponding defrosting operation according to the light transmittance of the windshield 20, so as to achieve the purpose of balancing defrosting efficiency, defrosting effect and energy saving and emission reduction.

[0092] Reference Figure 4 The flowchart illustrates the steps of a second defrosting mode according to an embodiment of this application, as shown below. Figure 4 As shown, the second defrosting mode may specifically include the following sub-steps:

[0093] Sub-step 1051: When the light transmittance meets the third preset range, the first main air outlet, the second main air outlet, the first secondary air outlet, and the second secondary air outlet all perform defrosting operations on the main area.

[0094] In this embodiment of the application, if the light transmittance of the windshield 20 meets the third preset range, it can be considered that the light transmittance of the windshield 20 is extremely poor. In order to ensure driving safety during the driving process, it is necessary to prioritize the efficient defrosting operation of the main area 201 of the windshield 20.

[0095] Specifically, when efficient defrosting of the main area 201 of the windshield 20 is required, the first main air vent 111, the second main air vent 121, the first secondary air vent 112, and the second secondary air vent 122 can all be used to defrost the main area 201 to quickly remove frost. By concentrating the hot air blown from the first main air vent 111, the first secondary air vent 112, the second main air vent 121, and the second secondary air vent 122 into the main area 201 of the windshield 20, the energy of the thermal system can be concentrated on the defrosting function of the main area 201, completing the defrosting function of the main area 201 in the shortest possible time and ensuring the driving safety of the user.

[0096] Optionally, the third preset range is greater than 0 and less than 30%, that is, when the light transmittance of the windshield 20 is greater than 0 and less than 30%, the light transmittance of the windshield 20 can be considered to be extremely poor. In order to ensure driving safety during the driving process, it is necessary to prioritize the efficient defrosting operation of the main area 201 of the windshield 20.

[0097] Sub-step 1052: When the light transmittance meets the fourth preset range, the first main air outlet, the second main air outlet, and the first auxiliary air outlet perform a defrosting operation on the main area, and the second auxiliary air outlet performs a defrosting operation on the auxiliary area.

[0098] In this embodiment of the application, if the light transmittance of the windshield 20 meets the fourth preset range, it can be considered that the light transmittance of the windshield 20 is poor. In order to ensure driving safety, it is necessary to prioritize the defrosting operation of the main area 201 of the windshield 20. At the same time, the defrosting operation of the secondary area 202 of the windshield 20 can also be carried out to achieve overall defrosting of the windshield 20.

[0099] Specifically, when it is necessary to prioritize defrosting the main area 201 of the windshield 20 while also defrosting the secondary area 202, the first main air outlet 111, the second main air outlet 121, and the first secondary air outlet 112 can be used to perform defrosting on the main area 201, prioritizing efficient defrosting of the main area 201 of the windshield 20. Simultaneously, the second secondary air outlet 122 is used to perform defrosting on the secondary area 202, thus achieving overall defrosting of the windshield 20.

[0100] Optionally, the fourth preset range is greater than or equal to 30% and less than 60%. That is, when the light transmittance of the windshield 20 is greater than or equal to 30% and less than 60%, it can be considered that, in order to ensure driving safety, the main area 201 of the windshield 20 should be defrosted first, while the secondary area 202 of the windshield 20 can also be defrosted to achieve overall defrosting of the windshield 20.

[0101] Sub-step 1053: When the light transmittance meets the fifth preset range, the first main air outlet and the second main air outlet perform a defrosting operation on the main area, and the first auxiliary air outlet and the second auxiliary air outlet perform a defrosting operation on the auxiliary area; wherein, the light transmittance that meets the fifth preset range is greater than the light transmittance that meets the fourth preset range; the light transmittance that meets the fourth preset range is greater than the light transmittance that meets the third preset range.

[0102] In this embodiment of the application, if the light transmittance of the windshield 20 meets the fifth preset range, it can be considered that the light transmittance of the windshield 20 is generally low, and it is necessary to perform defrosting operation on both the main area 201 and the sub-area 202 of the windshield 20 at the same time to ensure driving safety.

[0103] Specifically, when the light transmittance of the windshield 20 meets the fifth preset range, the first main air outlet 111 and the second main air outlet 121 can be used to perform defrosting operation on the main area 201, while the first secondary air outlet 112 and the second secondary air outlet 122 can be used to perform defrosting operation on the secondary area 202, so as to achieve a better defrosting effect and defrosting efficiency.

[0104] Optionally, the fifth preset range is greater than or equal to 60% and less than 90%. That is, when the light transmittance of the windshield 20 is greater than or equal to 60% and less than 90%, it can be considered that the main area 201 and the secondary area 202 of the windshield 20 need to be defrosted simultaneously to ensure driving safety.
