[0040] Here, the technical solutions in the embodiments (or "implementations") of the present application will be described clearly and completely in conjunction with the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0041] If there are terms involving directional indications or positional relationships in the embodiments of the present application (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationship, movement, etc. between the components under a certain specific posture (as shown in the accompanying drawings); if the specific posture changes, the directional indication or positional relationship will also change accordingly. In addition, the terms "first", "second", etc. involved in the embodiments of the present application are only used for the purpose of convenience of description and cannot be understood as indicating or implying relative importance.

[0042] For the sake of aesthetics, the door handle is usually set as a hidden door handle, that is, a pit is provided on the outer surface of the door sheet metal, and the door handle is installed in the pit and does not protrude from the outer surface of the door sheet metal. In rainy and snowy weather, snow and water are easily accumulated in the pit, causing the door handle to be frozen and difficult to open.

[0043] In order to prevent the door handle from freezing, an airbag can be wrapped around the outside of the door handle. The airbag can be controlled to inflate and deflate to make the ice fall off and achieve de-icing. At the same time, a vibration component can be set on the inside of the door handle. The vibration component can be controlled to vibrate and transmit to the door handle to achieve de-icing.

[0044] Please refer to Figure 1 , Figure 1 The present invention is a flowchart of a method for controlling the antifreeze of a vehicle door handle according to an exemplary embodiment of the present application.

[0045] The present application provides an antifreeze control method for a vehicle door handle, comprising step S10, step S20, step S30 and step S40.

[0046] Step S10, obtaining the current weather information of the vehicle's environment.

[0047] Meteorological information includes, but is not limited to, temperature, humidity, rainfall, snowfall, wind level, etc. For example, meteorological information can be obtained through temperature sensors, humidity sensors, rainfall sensors, and wind sensors, but is not limited thereto.

[0048] Step S20, determining whether the meteorological information meets a threshold condition, and if so, executing step S30. The threshold condition may be a meteorological condition that produces freezing, such as rainfall, temperature, etc., but is not limited thereto. The threshold condition may be determined by experiment.

[0049] Step S30, controlling the airbag wrapped around the outside of the door handle to inflate and maintain it in an expanded state after inflation.

[0050] Step S40, in response to the opening signal of the door handle, controlling the airbag to deflate. The opening signal can be generated when the car owner carries a signal key close to the car door, or when the car owner controls the car remotely, or according to a preset program.

[0051] According to the above description, if the current weather information in the environment where the vehicle is located meets the threshold conditions for freezing, the airbag can be controlled to inflate. After the airbag is inflated, it expands and increases in volume, which can occupy the space around the door handle, thereby reducing the accumulation of snow and water in the pit. When the door handle is opened, the airbag is controlled to deflate. After the airbag is deflated, it resets, which can drive the ice layer to fall off during the reset process, realize deicing, and thus reduce the risk of the door handle being frozen.

[0052] In step S10, the meteorological information can be obtained through a camera, a temperature sensor, a humidity sensor, and a rainfall sensor. For example, the camera can collect images of the external environment and identify whether it is currently raining or snowing through the images. The temperature sensor can collect the external environment temperature, the humidity sensor can collect the external humidity, the rainfall sensor can collect the rainfall, etc. The above sensors can be used in combination or alone.

[0053] In step S10, the vehicle's current location information can also be obtained through a positioning system, and the weather information of the current region can be obtained based on the region information. The positioning system includes but is not limited to a GPS satellite positioning system and a map navigation system.

[0054] In one embodiment, step S30 may specifically include: controlling the airbag to inflate and expand until it is flush with the outer surface of the door sheet metal, stopping the inflation, and maintaining the inflated state. In this way, when the inflated airbag is flush with the outer surface of the door sheet metal, most of the area in the pit is filled, which can further reduce the amount of snow and water accumulated in the pit, thereby reducing the risk of freezing between the airbag and the door sheet metal. Even if freezing occurs, the ice layer is relatively thinner, and it is easier to make the ice layer fall off when the airbag is deflated, and deicing is more reliable.

[0055] During the actual inflation process of the airbag, the inflated airbag can be made flush with the outer surface of the door sheet metal by controlling the inflation time, and the inflated airbag can also be made flush with the outer surface of the door sheet metal by detecting the pressure inside the airbag. It should be noted that the above inflation time and pressure value can be determined by experiment.

[0056] Please refer to Figure 2 , Figure 2 The present invention is a flowchart of a method for controlling the antifreeze of a vehicle door handle according to an exemplary embodiment of the present application.

[0057] exist Figure 2 In the embodiment shown, the antifreeze control method for the door handle includes steps S10, S20, S30, S40 and S50. Steps S10, S20, S30 and S40 are similar to Figure 1 The same as shown in , will not be repeated here.

[0058] Step S50, determining whether the airbag is reset after being deflated.

[0059] For example, the image of the airbag can be captured by a camera, and the airbag can be judged whether it is reset based on the image, but it is not limited to this. For example, a contact sensor can also be used to detect whether the airbag is reset. If the airbag is deflated and reset, it means that the de-icing is successful, and the door handle can be opened normally.

[0060] Step S60: If the airbag is not reset after being deflated, a vibration motor installed in the door handle is controlled to vibrate.

[0061] In the above embodiment, if the airbag does not reset after being deflated, it means that the airbag and the door sheet metal are frozen, and de-icing fails. At this time, the vibration component can be controlled to vibrate and transmit the vibration to the door handle to make the ice fall off, thereby improving the de-icing effect. The vibration component includes but is not limited to a vibration motor and an ultrasonic transducer.

[0062] In an optional embodiment, in step S60, the vibration component installed in the door handle is controlled to vibrate at the natural frequency of the door handle. This arrangement can increase the amplitude of the door handle, making the vibration more intense, and thus improve the deicing effect. The natural frequency can be calculated according to the formula: Where k is the stiffness and m is the mass of the system. The natural frequency can also be determined experimentally.

[0063] In another embodiment, in step S60, the vibration component installed in the door handle can also be controlled to vibrate at preset frequencies from small to large until the deflated airbag is normally reset. Specifically, in the initial stage, the vibration component can be made to vibrate at a smaller frequency and the vibration time can be set. If the airbag still does not reset normally after the set vibration time, the vibration component is controlled to vibrate at a larger frequency and the vibration time can be set. The preset frequencies can be two or more, and the values ​​of each frequency increase in sequence, and the duration can be equal or different.

[0064] Please refer to Figure 3 , Figure 3 The present invention is a flowchart of a method for controlling the antifreeze of a vehicle door handle according to an exemplary embodiment of the present application.

[0065] exist Figure 3 In the embodiment shown, the antifreeze control method for the door handle includes step S05, step S08, step S10, step S20, step S30 and step S40. Among them, step S10, step S20, step S30 and step S40 are the same as Figure 1 The same as shown in , will not be repeated here.

[0066] Step S05, obtaining the time after the vehicle is turned off.

[0067] Step S08, determining whether the duration reaches a preset duration, if so, executing step S10. The preset duration can be set according to actual conditions, for example, 1 hour, 2 hours, but not limited thereto.

[0068] That is, when the time after the vehicle is turned off reaches the preset time, steps S10 to S40 are executed, otherwise steps S10 to S40 are not executed, which prevents the airbag from being inflated during the use of the vehicle. This arrangement can, on the one hand, prepare for deicing when the vehicle is likely to freeze after the vehicle is turned off, and on the other hand, it can also reduce the risk of the airbag being damaged during the use of the vehicle.

[0069] Please refer to Figure 4 , Figure 4 The present invention is a flowchart of a method for controlling the antifreeze of a vehicle door handle according to an exemplary embodiment of the present application.

[0070] exist Figure 4 In the embodiment shown, the antifreeze control method for the door handle includes step S10, step S20, step S30 and step S40'. Figure 1 The same as shown in , will not be repeated here.

[0071] Step S40 ′, responding to an opening signal generated when the distance between the user and the vehicle door reaches a preset distance.

[0072] In step S40', when the distance between the user and the car door reaches a preset distance, considering that the user intends to open the car door, the airbag can be controlled to deflate, making the antifreeze control method more intelligent. The preset distance can be 0.5m, 1m, 2m, but is not limited thereto.

[0073] Of course, in some other embodiments, an opening signal for opening the door handle may also be generated through a mobile phone APP and a car key.

[0074] In one embodiment, the antifreeze control method further includes: controlling the indicator light to light up while controlling the airbag to deflate. The indicator light can provide lighting for the user or be used as a welcoming effect, or prompt the user whether the door handle is opened smoothly, etc., to improve the user experience.

[0075] In a specific embodiment, the indicator light can be controlled to light up in different ways according to the state of the door handle.

[0076] The first method is to control the indicator light to light up in a welcoming manner while controlling the airbag to deflate. For example, the indicator light emits white light after lighting up, and the indicator lights can light up in sequence, thereby achieving a welcoming effect, but is not limited to this. At this time, the door handle begins to be de-iced.

[0077] The second method: if the airbag is not reset after being deflated, the indicator light is controlled to change color and displayed in a first color. The first color may be red, and the indicator light flashes and lights up after a few seconds, but is not limited thereto. If the airbag is not reset after being deflated, it means that the de-icing has failed.

[0078] The third method: if the airbag is reset after deflation, the control indicator light changes color and is displayed in a second color. The second color may be green, and the indicator light flashes and turns off after a few seconds, but is not limited to this. The airbag is reset after deflation, indicating that the de-icing is successful.

[0079] Please refer to Figure 5 , Figure 5 A schematic diagram of an antifreeze control device for a vehicle door handle shown as an exemplary embodiment of the present application.

[0080] The present application also provides an antifreeze control device 100 for a vehicle door handle, and the antifreeze control device 100 includes an acquisition module 10 , a judgment module 20 and a control module 30 .

[0081] The acquisition module 10 is used to obtain the current meteorological information of the environment where the vehicle is located. The acquisition module 10 includes but is not limited to a camera, a temperature sensor, a humidity sensor, and a rain sensor. For example, the camera can capture images of the external environment and identify whether it is currently raining or snowing through the image. The temperature sensor can collect the external environment temperature, the humidity sensor can collect the external humidity, the rain sensor can collect the rainfall, etc. The above sensors can be used in combination or alone. The acquisition module 10 can also include a positioning system, and the positioning system includes but is not limited to a GPS satellite positioning system and a map navigation system. The positioning system obtains the current geographical information of the vehicle, and obtains the meteorological information of the current region based on the regional information.

[0082] The determination module 20 is connected to the acquisition module 10 and is used to determine whether the meteorological information meets a threshold condition.

[0083] The control module 30 is connected to the judgment module 20 and outputs a control signal according to the judgment result. If the judgment result is that the meteorological information meets the threshold condition, a control signal is output to control the airbag wrapped around the outside of the door handle to inflate and maintain the expanded state after inflation. The control module 30 is also used to control the deflation of the airbag in response to the opening signal of the door handle. The device 100 can control the inflation and deflation of the airbag, and the deflation of the airbag can drive the ice layer to fall off, realize deicing, and thus reduce the risk of the door handle being frozen.

[0084] In one embodiment, the control module 30 is also used to control the airbag to stop inflating when it is inflated and expanded to be flush with the outer surface of the door sheet metal, and keep it in the expanded state after inflating. For example, the device 100 may include a timer or a pressure sensor, and the timer or the pressure sensor inputs a corresponding signal to the control module 30, and the control module 30 controls the airbag inflation amount according to the signal, so as to ensure that the airbag inflation amount is appropriate to meet the antifreeze requirements.

[0085] In one embodiment, the acquisition module 10 is further used to acquire the time after the vehicle is turned off, and acquire the weather information when the time reaches a preset time. This arrangement can, on the one hand, prepare for deicing when the vehicle is likely to freeze after the vehicle is turned off, and on the other hand, reduce the risk of the airbag being damaged during vehicle use.

[0086] In one embodiment, the antifreeze control device 100 further includes an indicator light 40, and the control module controls the indicator light 40 to light up in response to the opening signal of the door handle. The indicator light 40 can provide lighting for the user or be used as a welcoming effect, or prompt the user whether the door handle is opened smoothly, etc., to improve the user experience.

[0087] The indicator light 40 can be lit in the following ways.

[0088] The first method is to control the indicator light to light up in a welcoming manner while controlling the airbag to deflate. For example, the indicator light emits white light after lighting up, and the indicator lights can light up in sequence, thereby achieving a welcoming effect, but is not limited to this. At this time, the door handle begins to be de-iced.

[0089] The second method: if the airbag is not reset after being deflated, the indicator light is controlled to change color and be displayed in a first color. The first color may be red, and the indicator light may be flashing, but is not limited thereto. If the airbag is not reset after being deflated, it means that the de-icing has failed.

[0090] The third method: if the airbag is reset after deflation, the control indicator light changes color and is displayed in a second color. The second color may be green, and the indicator light may be flashing, but is not limited thereto. The airbag being reset after deflation indicates that de-icing is successful.
