[0050] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0051] The embodiment of the present application provides a window glass water cut sealing structure, a vehicle and a control method, which can solve the problem that abnormal noises are generated during the lifting and lowering of the window glass due to the humidity and temperature differences between the inner and outer water cut sealing strips of the door in the related art.

[0052] See Figures 1 to 4 As shown, in the first aspect of the embodiment of the present application, a window glass water cut sealing structure is provided, including:

[0053] An outer water cut sealing strip 10, which includes an outer water cut elastic lip 11. The outer water cut elastic lip 11 is used for sliding and sealing connection with the outer surface of the window glass, and is used to cut off water droplets, water mist and dust on the surface of the window glass during the process of lifting and lowering the window glass. A first temperature and humidity sensor 12 is provided on the outer water cut elastic lip 11, and the first temperature and humidity sensor 12 is used to detect the temperature and humidity information of the outer water cut elastic lip 11.

[0054] An inner water cut sealing strip (not shown in the figure), the structure of the inner water cut sealing strip is similar to that of the outer water cut sealing strip 10. The inner water cut sealing strip includes an inner water cut elastic lip (not shown in the figure), and the inner water cut elastic lip can cut off water droplets, water mist and dust on the surface of the window glass. A second temperature and humidity sensor 16 is provided on the inner water cut elastic lip, and the second temperature and humidity sensor 16 is used to detect the temperature and humidity information of the inner water cut elastic lip.

[0055] The resistance heating wire 13 is attached to the outer water cut sealing strip 10 to heat the outer water cut sealing strip 10. After the resistance heating wire 13 is powered on, it is used to heat the outer water cut sealing strip 10 to keep the temperature or humidity of the outer water cut sealing strip 10 within a certain range. This avoids the occurrence of frictional abnormal noise caused by excessive differences in humidity and temperature between the outer water cut sealing strip 10 and the inner water cut sealing strip.

[0056] The vehicle controller 30, the first temperature and humidity sensor 12, the second temperature and humidity sensor 16, and the electric resistance heating wire 13 are all connected to the vehicle controller 30. The vehicle controller 30 first obtains the temperature values and humidity values collected by the first temperature and humidity sensor 12 and the second temperature and humidity sensor 16 respectively, and then determines whether to control the electric resistance heating wire 13 to heat the outer water cut sealing strip and the inner water cut sealing strip according to the difference in humidity values and the difference in temperature values. When the temperature difference and humidity difference between the outer water cut sealing strip 10 and the inner water cut sealing strip are both controlled within a certain range, the occurrence of such abnormal noise can be greatly reduced.

[0057] In the window glass water cut sealing structure of the embodiment of the present application, a first temperature and humidity sensor 12 for detecting the temperature and humidity information of the outer water cut sealing strip 10 is provided on the outer water cut elastic lip 11 of the outer water cut sealing strip 10, and a second temperature and humidity sensor for detecting the temperature and humidity information of the inner water cut sealing strip is provided on the inner water cut elastic lip of the inner water cut sealing strip.

[0058] The vehicle controller 30 can control the electric resistance heating wire 13 for heating the outer water cut sealing strip 10 to perform heating and dehumidification by obtaining the temperature and humidity information of the outer water cut sealing strip 10 and the temperature and humidity information of the inner water cut sealing strip. When the temperature and humidity of both the outer water cut sealing strip 10 and the inner water cut sealing strip are kept within a certain range, the occurrence of such abnormal noise can be greatly reduced.

[0059] In some alternative embodiments: Refer to Figures 1 to 4 As shown, in the first aspect of the embodiment of the present application, a window glass water cut sealing structure is provided. The outer water cut sealing strip 10 of the window glass water cut sealing structure further includes an outer water cut sealing main body 14 connected to the vehicle door, and a metal support frame 15 is embedded in the outer water cut sealing main body 14. The resistance heating wire 13 is attached between the metal support frame 15 and the outer water cut sealing main body 14 along the length direction of the metal support frame 15.

[0060] The inner water cut sealing strip also includes an inner water cut sealing main body (not shown in the figure) connected to the vehicle door, and a metal support frame 15 is embedded in the inner water cut sealing main body. The resistance heating wire 13 is fixed on the metal support frame 15, and the metal support frame 15 has a good heat transfer effect. When the resistance heating wire 13 heats the metal support frame 15, the metal support frame 15 evenly transfers the heat of the resistance heating wire 13 to the outer water cut sealing strip 10 to achieve uniform heating of the outer water cut sealing strip 10.

[0061] In some alternative embodiments: Refer to Figures 1 to 4 As shown, in the first aspect of the embodiments of the present application, a window glass water cut sealing structure is provided. One end of the outer water cut elastic lip 11 of the window glass water cut sealing structure is a fixed end and is integrally connected to the outer water cut sealing body 14. The other end of the outer water cut elastic lip 11 is a free end. A groove is formed between the outer water cut elastic lip 11 and the outer water cut sealing body 14, and the groove provides a movement space for the elastic deformation of the outer water cut elastic lip 11.

[0062] The surface of the outer water cut elastic lip 11 close to the window glass 20 is in sliding sealing fit with the outer surface of the window glass 20. The first temperature and humidity sensor 12 is fixed on the surface of the outer water cut elastic lip 11 away from the window glass. The first temperature and humidity sensor 12 neither affects the sliding sealing connection between the outer water cut elastic lip 11 and the window glass 20, nor can it more accurately detect the temperature information and humidity information of the outer water cut elastic lip 11.

[0063] In some alternative embodiments: Refer to Figures 1 to 4 As shown, in the first aspect of the embodiments of the present application, a window glass water cut sealing structure is provided. One end of the inner water cut elastic lip of the window glass water cut sealing structure is a fixed end and is integrally connected to the inner water cut sealing body. The other end of the inner water cut elastic lip is a free end. A groove is formed between the inner water cut elastic lip and the inner water cut sealing body, and the groove provides a movement space for the elastic deformation of the inner water cut elastic lip.

[0064] The surface of the inner water cut elastic lip close to the window glass 20 is in sliding sealing fit with the inner surface of the window glass 20. The second temperature and humidity sensor 16 is fixed on the surface of the inner water cut elastic lip away from the window glass 20. The second temperature and humidity sensor 16 neither affects the sliding sealing connection between the inner water cut elastic lip and the window glass 20, nor can it more accurately detect the temperature information and humidity information of the inner and outer water cut elastic lips.

[0065] In some alternative embodiments: Refer to Figures 1 to 4 As shown, in the first aspect of the embodiments of the present application, a window glass water cut sealing structure is provided. The first temperature and humidity sensor 12 of the window glass water cut sealing structure includes a plurality of first temperature sensors installed on the outer water cut elastic lip 11, and a plurality of first humidity sensors installed on the outer water cut elastic lip. The plurality of first temperature sensors and the plurality of first humidity sensors are both connected to the vehicle controller 30, and the vehicle controller 30 obtains the average temperature value and average humidity value detected by the plurality of first temperature sensors and the plurality of first humidity sensors.

[0066] The second temperature and humidity sensor 16 includes one or more second temperature sensors installed on the inner water cut elastic lip, and one or more second humidity sensors installed on the outer water cut elastic lip. The multiple first temperature sensors and multiple first humidity sensors are used to detect the temperature information and humidity information of the outer water cut elastic lip 11 respectively. The one or more second temperature sensors and the one or more second humidity sensors are used to detect the temperature information and humidity information of the inner water cut elastic lip respectively.

[0067] In the second aspect of the embodiments of the present application, a vehicle is provided, and the vehicle uses the window glass water cut sealing structure described in any of the above embodiments.

[0068] See Figures 1 to 4 As shown, in the third aspect of the embodiments of the present application, a control method for a window glass water cut sealing structure is provided. The method uses the window glass water cut sealing structure described in any of the above embodiments, and the method includes:

[0069] S101, the vehicle controller 30 obtains the humidity values of the outer water cut sealing strip 10 and the inner water cut sealing strip respectively detected by the first temperature and humidity sensor 12 and the second temperature and humidity sensor 16.

[0070] S102, the vehicle controller 30 determines whether the humidity difference between the humidity value of the outer water cut sealing strip 10 and the humidity value of the inner water cut sealing strip is less than the humidity limit value Y.

[0071] S103, if not, the vehicle controller 30 controls the resistance heating wire 13 to start heating until the humidity difference is less than the humidity limit value Y.

[0072] S104, if so, the vehicle controller 30 obtains the temperature value of the outer water cut sealing strip 10 detected by the first temperature and humidity sensor 12 and the temperature value of the inner water cut sealing strip detected by the second temperature and humidity sensor 16.

[0073] S105, the vehicle controller 30 determines whether the temperature of the outer water cut sealing strip 10 is greater than the temperature limit value X1. If so, the resistance heating wire 13 is prevented from heating.

[0074] S105, if the temperature of the outer water cut sealing strip 10 is less than the temperature limit value X1, the temperature difference between the first temperature and humidity sensor 12 and the second temperature and humidity sensor 16 is calculated.

[0075] S106, if the temperature difference between the first temperature and humidity sensor 12 and the second temperature and humidity sensor 16 is less than the temperature limit value X2, the resistance heating wire 13 is prevented from heating.

[0076] S107, if the temperature difference is greater than the temperature limit value X2, the resistance heating wire 13 is started to heat.

[0077] The control method of the window glass water cut sealing structure according to the embodiments of the present application is greatly affected by humidity in terms of abnormal noises generated by the outer water cut elastic lip 11 and the inner water cut elastic lip. Therefore, controlling the humidity of the outer water cut elastic lip 11 and the inner water cut elastic lip takes precedence over temperature.

[0078] If the vehicle controller 30 determines that the humidity difference between the humidity value of the outer water cut sealing strip 10 and the humidity value of the inner water cut sealing strip is greater than the humidity limit value Y, the vehicle controller 30 activates the resistance heating wire 13 for heating until the humidity difference is less than the humidity limit value Y.

[0079] After the humidity difference is less than the humidity limit value Y, it is determined whether the temperature of the outer water cut sealing strip 10 is greater than the temperature limit value X1. The temperature limit value X1 is preferably the outdoor environmental temperature in winter, and this temperature limit value X1 is preferably zero degree and below.

[0080] When the temperature of the outer water cut sealing strip 10 is less than the temperature limit value X1, the temperature difference between the first temperature and humidity sensor 12 and the second temperature and humidity sensor 16 is calculated. If the temperature difference is greater than the temperature limit value X2, the resistance heating wire 13 is activated for heating to make the temperature values of the outer water cut sealing strip 10 and the inner water cut sealing strip tend to be consistent.

[0081] In some alternative embodiments: The embodiments of the present application provide a control method for a window glass water cut sealing structure. Between the step where the temperature difference is greater than the temperature limit value X2 and the step of activating the resistance heating wire 13 for heating in the method S107, it further includes:

[0082] S201, the vehicle controller 30 makes a vehicle speed judgment, and the vehicle controller 30 can obtain the current vehicle speed information of the vehicle in real time.

[0083] S202, if the current vehicle speed is greater than the vehicle speed limit value V, the resistance heating wire 13 is prevented from heating. When the current vehicle speed is greater than the vehicle speed limit value V, for example, when the vehicle speed limit value V is 80 km / h, the window glass 20 will not be operated for lifting or lowering.

[0084] S203, if the current vehicle speed is less than the vehicle speed limit value V, the resistance heating wire 13 is activated for heating.

[0085] In some alternative embodiments: The embodiments of the present application provide a control method for a window glass water cut sealing structure. After the step of activating the resistance heating wire 13 for heating in the method S107, it further includes:

[0086] S301, the vehicle controller 30 determines whether the temperature of the outer water cut sealing strip is greater than the temperature limit value X3. The temperature limit value X3 is the temperature value at which the outer water cut sealing strip melts minus the safety threshold.

[0087] In S302, if so, the vehicle controller 30 pauses the heating of the resistance heating wire 13 until the temperature of the outer water cut sealing strip 10 is less than X3 - n, where n is a positive number, and then resumes heating.

[0088] In S303, if not, the vehicle controller 30 continues to control the heating of the resistance heating wire 13 until the heating stops after reaching the shutdown condition, and the shutdown condition includes:

[0089] Any one of the outer water cut sealing strip temperature being greater than the temperature limit value X1, the temperature difference between the first temperature and humidity sensor 12 and the second temperature and humidity sensor 16 being less than the temperature limit value X2, and the current vehicle speed being greater than the vehicle speed limit value V.

[0090] Since the installation positions of the first temperature and humidity sensor 12 and the second temperature and humidity sensor 16 are both at a certain distance from the window glass 20, the temperatures of the first temperature and humidity sensor 12 and the second temperature and humidity sensor 16 are inconsistent with the temperature of the actual contact with the window glass 20. Therefore, multi - condition calibration is required. Through the processing of the vehicle controller 30, the monitoring values of the first temperature and humidity sensor 12 and the second temperature and humidity sensor 16 are corrected for judgment.

[0091] Determination of the humidity limit value Y:

[0092] At a certain temperature (room temperature), different humidity gradients in the environmental chamber are set. The outer water cut sealing strip 10 is placed for a certain time (20 min) in each environmental state. The window glass 20 is repeatedly raised and lowered multiple times until a frictional abnormal sound appears at a certain humidity, and thus the corresponding humidity limit value Y is determined.

[0093] Determination of the temperature difference X2:

[0094] When the humidity difference is at the humidity limit value Y, at a certain temperature (room temperature), different environmental chamber temperatures are set. The outer water cut sealing strip 10 is placed until its temperature is consistent with the set value of the environmental chamber in each environmental state, and then the window glass 20 is repeatedly raised and lowered multiple times until a frictional abnormal sound appears at a certain temperature difference, and thus the corresponding temperature difference X2 is determined.

[0095] Determination of the temperature limit value X1:

[0096] When the humidity difference is at the limit value Y, the outer water cut sealing strip 10 and the inner water cut sealing strip are placed in two environmental chambers (the temperature difference between the two environmental chambers is X2, and the temperature of the inner water cut sealing strip is high and the temperature of the outer water cut sealing strip 10 is low). The window glass 20 is repeatedly raised and lowered multiple times at each set value until a frictional abnormal sound appears at a certain environmental temperature, and thus the corresponding temperature limit value X1 is determined.
