Description

Technical Field

[0001] The utility model relates to the technical field of deicing, in particular to a vehicle-mounted deicing device, a door assembly and a vehicle. Background Art

[0002] Currently, the hidden handle has become one of the common components of automobiles, with a strong sense of technology and aesthetic appearance, and can also reduce wind resistance and wind noise. However, in cold and snowy weather, if the ambient temperature drops below the freezing point, for a car parked outdoors, the gap between the hidden handle and the door may condense into ice due to residual rain and snow, freezing the hidden handle to the door. At the same time, since the hidden handle and the door are flush with the door panel, when frozen, the hidden handle cannot be actively or passively ejected, and there is no force application point for ice breaking, which affects the user experience.

[0003] To solve this problem, methods such as violent ice breaking or heating deicing are usually adopted. However, violent ice breaking is likely to cause damage to the car paint, and the heating deicing takes a long time. The car owner needs to wait for heating in the cold weather, and the deicing effect is not good. Summary of the Utility Model

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0036] An embodiment of the present utility model provides a vehicle-mounted de-icing device, as Figure 1 shown, which includes a control module, a radar detection module 1, and a blower; the radar detection module 1 is arranged on the vehicle door 2 and is used to perform radar detection on the gap between the hidden handle 3 and the vehicle door 2 to obtain a radar detection result; the blower is arranged on the vehicle door 2 or the vehicle body, and the air outlet of the blower is arranged opposite to the gap between the hidden handle 3 and the vehicle door 2; the control module is connected to the radar detection module 1 and the blower and is used to control the blower to work according to the radar detection result.

[0037] As an example, the vehicle-mounted de-icing device includes a control module, a radar detection module 1, and a blower. The vehicle-mounted de-icing device can be arranged on the door assembly, which includes a door 2 and a hidden handle 3 arranged on the door 2. There is a gap between the hidden handle 3 and the door 2. The control module in the vehicle-mounted de-icing device is arranged inside the door 2, or the control module is an integrated control module in the vehicle. The radar detection module 1 in the vehicle-mounted de-icing device can be arranged on the door 2 and can detect the gap between the hidden handle 3 and the door 2. Specifically, it can detect the current width of the gap between the hidden handle 3 and the door 2. The control module is connected to the radar detection module 1 and can compare the current width with a preset standard width to determine whether there is ice and snow in the gap. When the control module determines that there is ice water or snow, it means that there is a risk of icing between the current hidden handle 3 and the door 2. The control module is also connected to the blower, and the air outlet of the blower is arranged opposite to the gap between the hidden handle 3 and the door 2. At this time, the control module controls the blower to start, and the air blown out from the air outlet can blow away the ice and snow between the hidden handle 3 and the door 2 to prevent the hidden handle 3 and the door 2 from icing and causing the door 2 to be unable to open.

[0038] In this example, by arranging the radar detection module 1 on the door 2, the gap between the hidden handle 3 and the door 2 can be detected to determine whether there is ice and snow in the gap and identify whether there is a risk of icing on the hidden handle 3. By arranging the blower, an air flow directly acting on the ice layer can be generated, quickly destroying the adhesion between the ice layer and the car paint surface, thus achieving rapid de-icing, which is more efficient than traditional physical knocking or chemical de-icing methods and will not damage the car paint. In addition, the vehicle-mounted de-icing device can identify the freezing risk of the hidden handle 3, prevent the handle from icing in advance, so that the hidden handle 3 will not freeze with the door 2, and the vehicle owner does not need to wait for de-icing.

[0039] In one embodiment, as Figure 2 shown, the radar detection module 1 includes a radar body and a detection probe 11. The radar body is arranged inside the door 2, and the detection probe 11 is arranged on the door 2 and is arranged opposite to the gap between the hidden handle 3 and the door 2.

[0040] As an example, the radar detection module 1 includes a radar body and a detection probe 11. The transmitter in the radar body can transmit electromagnetic waves to the gap through the detection probe 11. After the electromagnetic waves encounter an object, they will be reflected in all directions, and a part of them can be reflected back in the direction of the radar, so that the receiver in the radar body can receive the electromagnetic waves through the detection probe 11, thus completing the detection of the object. In this example, the radar body is arranged inside the vehicle door 2, and the detection probe 11 is arranged on the surface of the vehicle door 2. The detection probe 11 is arranged opposite to the gap between the hidden handle 3 and the vehicle door 2, so that the radar body can transmit electromagnetic waves to the gap between the hidden handle 3 and the vehicle door 2. When there is ice and snow in the hidden handle 3, the electromagnetic waves transmitted by the radar body are reflected by the ice and snow, and the radar body detects the reflected electromagnetic waves, so that it can detect the existence of ice and snow in the gap, indicating that the hidden handle 3 has a risk of icing at this time, and the blower needs to be started for deicing.

[0041] In one embodiment, the vehicle-mounted deicing device further includes a temperature detection module; the temperature detection module is arranged on the vehicle door 2 or the vehicle body and is used for collecting the ambient temperature; the control module is also connected to the temperature detection module and is used for controlling the operation of the radar detection module 1 according to the ambient temperature.

[0042] As an example, the vehicle-mounted deicing device further includes a temperature detection module. The temperature detection module is arranged on the vehicle, and specifically can be arranged on the outer panel 21 of the vehicle door or the vehicle body to identify the ambient temperature on the outer surface of the vehicle body. The control module is connected to the temperature detection module, and according to the ambient temperature, it can judge whether the outer surface of the vehicle body reaches the icing condition, so as to control the operation of the radar detection module 1. For example, when the control module detects that the ambient temperature is lower than zero degrees, it judges that the current outer surface of the vehicle body reaches the icing condition and controls to turn on the radar detection module 1; when it detects that the ambient temperature is not lower than zero degrees, it judges that the current outer surface of the vehicle body does not reach the icing condition and controls to turn off the radar detection module 1. By adding a temperature detection module to the vehicle-mounted deicing device, it can be judged whether the current ambient temperature reaches the icing condition, and the radar detection module 1 is controlled to start working only when the ambient temperature reaches the icing condition, which can reduce the power consumption of the radar detection module 1 and play a role in energy saving.

[0043] In one embodiment, the temperature detection module includes at least one temperature sensor; the temperature sensor is arranged on the vehicle door 2 or the vehicle body and is used for collecting the ambient temperature; the control module is connected to the temperature sensor and is used for controlling the operation of the radar detection module 1 according to the ambient temperature.

[0044] As an example, the temperature detection module includes at least one temperature sensor. The temperature sensor may include a thermistor disposed on the outer panel 21 of the vehicle door or on the vehicle body. The thermistor can generate a resistance change according to the ambient temperature of the outer surface of the vehicle body, so as to generate an electrical signal corresponding to the ambient temperature in the temperature sensor. The temperature sensor transmits the electrical signal to the control module, and the control module can obtain the ambient temperature according to the electrical signal, and then control the operation of the radar detection module 1.

[0045] The embodiment of the present utility model further provides a vehicle door assembly, as Figure 3 shown, which includes a vehicle door 2, a hidden handle 3 and the vehicle-mounted de-icing device in any of the above embodiments; the vehicle-mounted de-icing device is disposed on the vehicle door 2 or on the vehicle body; the hidden handle 3 is rotatably connected to the vehicle door 2, and when the hidden handle 3 is in the closed position, there is a gap between the hidden handle 3 and the vehicle door 2.

[0046] As an example, the vehicle door assembly includes a vehicle door 2, a hidden handle 3 and the vehicle-mounted de-icing device in any of the above examples. The hidden handle 3 is rotatably connected to the vehicle door 2. When the hidden handle 3 is in the closed position, the hidden handle 3 covers the vehicle door 2, the outer surface of the hidden handle 3 is flush with the outer surface of the vehicle door 2, and there is a gap between the edge of the hidden handle 3 and the outer surface of the vehicle door 2. The radar detection module 1 in the vehicle-mounted de-icing device can be disposed on the vehicle door 2 to detect the gap between the hidden handle 3 and the vehicle door 2. The control module is disposed inside the vehicle door 2, or the control module is an integrated control module in the vehicle. The control module is connected to the radar detection module 1 and can judge whether there is ice and snow in the gap according to the gap between the hidden handle 3 and the vehicle door 2. When the control module determines that there is ice water or snow, it controls the blower to be turned on to blow the ice and snow between the hidden handle 3 and the vehicle door 2, so as to prevent the hidden handle 3 and the vehicle door 2 from freezing and causing the vehicle door 2 to be unable to open.

[0047] In this example, by arranging a vehicle-mounted de-icing device in the vehicle door assembly, the gap between the hidden handle 3 and the vehicle door 2 can be detected to judge whether there is ice and snow in the gap. When there is ice and snow, an air flow directly acting on the ice layer is generated by the blower, which quickly destroys the adhesion between the ice layer and the paint surface of the vehicle, so as to achieve rapid de-icing, which is more efficient than the traditional physical knocking or chemical de-icing methods and will not damage the paint. In addition, the vehicle-mounted de-icing device can identify the freezing risk of the hidden handle 3 and prevent the handle from freezing in advance, so that the hidden handle 3 will not freeze with the vehicle door 2, and the vehicle owner does not need to wait for de-icing.

[0048] In one embodiment, as Figure 2 and Figure 4As shown, the vehicle door 2 includes an outer door panel 22 and a handle groove 21 recessed from one side surface of the outer door panel 22 along a first direction; one end of the hidden handle 3 is rotatably connected to the inner wall of the handle groove 21; when the hidden handle 3 is in the closed position, the hidden handle 3 covers the handle groove 21, and there is a gap between the outer edge of the hidden handle 3 and the handle groove 21.

[0049] As an example, the vehicle door 2 includes an outer door panel 22 and a handle groove 21 recessed from one side surface of the outer door panel 22 along a first direction. The handle groove 21 is used to form a receiving space for assembling the hidden handle 3. One end of the hidden handle 3 is rotatably connected to the inner wall of the handle groove 21. When the hidden handle 3 is in the closed position, the hidden handle 3 covers the vehicle door 2, the outer surface of the hidden handle 3 is flush with the outer surface of the vehicle door 2, and there is a gap between the outer edge of the hidden handle 3 and the outer surface of the vehicle door 2.

[0050] In one embodiment, as Figure 4 shown, at least one air outlet hole 4 is formed in the handle groove 21.

[0051] As an example, at least one air outlet hole 4 is formed in the inner wall of the handle groove 21 for communicating the spaces inside and outside the outer door panel 22, so that the blower assembled inside the vehicle door 2 or on the vehicle body can smoothly blow air between the outer door panel 22 and the hidden handle 3. By providing a plurality of air outlet openings, it is beneficial to increase the air volume and improve the de-icing efficiency.

[0052] In one embodiment, as Figure 1 and Figure 2 shown, the air outlet hole 4 is disposed opposite to the gap between the hidden handle 3 and the vehicle door 2.

[0053] As an example, the gap between the vehicle door 2 and the hidden handle 3 projects onto the inner side wall of the handle groove 21 to form a distribution path. The air outlet holes 4 are spaced apart on the distribution path and are disposed opposite to the gap between the hidden handle 3 and the vehicle door 2, so that the air outlet openings can be aligned with the gap to blow air and improve the de-icing efficiency.

[0054] In one embodiment, as Figure 4 shown, the vehicle door assembly further includes at least one air duct 5 disposed between the blower and the air outlet hole 4; the first end of each air duct 5 is connected to the air outlet of the blower, and the second end of the air duct 5 is connected to the air outlet.

[0055] As an example, the door assembly further includes at least one air duct 5 disposed between the blower and the air outlet 4. The first ends of the plurality of air ducts 5 are all connected to the air outlet of the blower, and the second end of each air duct 5 is connected to an air outlet 4, so that the air blown by the blower can be blown out from the air outlet 4 along the air duct 5, preventing the blown air from escaping inside the inner panel of the door 2, enhancing the air blowing effect, and improving the deicing efficiency.

[0056] The embodiment of the present invention further provides a vehicle, including the door assembly in any of the above embodiments.

[0057] As an example, the vehicle includes the door assembly in any of the above examples. In this example, by providing an in-vehicle deicing device in the door assembly, the gap between the hidden handle 3 and the door 2 can be detected to determine whether there is ice or snow in the gap. When there is ice or snow, an air flow directly acting on the ice layer is generated by the blower, quickly destroying the adhesion between the ice layer and the paint surface, thereby achieving rapid deicing, which is more efficient than traditional physical knocking or chemical deicing methods and will not damage the paint. In addition, the in-vehicle deicing device can identify the freezing risk of the hidden handle 3 and prevent the handle from freezing in advance, so that the hidden handle 3 will not freeze to the door 2, and the vehicle owner does not need to wait for deicing.
