Referring to fig. 1 to 3, the present embodiment provides a vehicle door handle device 100, the vehicle door handle device 100 includes a door handle 10 and a heating element 20, the heating element 20 is disposed at an opening and closing position of the door handle 10 and is used for heating the door handle 10.

The vehicle door handle device 100 according to the embodiment of the present application includes the heating element 20, and the heating element 20 heats the door handle 10, so that frost may exist at a gap between the door handle 10 and the door handle 10, and the door handle 10 may be smoothly ejected from the vehicle door 201, thereby ensuring the normal operation of the door handle 10 in cold weather.

In the embodiment of the present application, the vehicle door handle device 100 may be a hidden door handle 10 of an automobile, and the hidden door handle 10 may make the lines of the automobile body smoother, thereby helping to reduce the wind resistance and increase the cruising ability of the automobile. The hidden door handle 10 is embedded in the vehicle door 201, and when a user needs to use the hidden door handle 10, the user can send a signal through a vehicle key to enable the hidden door handle 10 to automatically pop up, and then the user opens the vehicle door 201 through the door handle 10.

It will be appreciated that there must be some clearance between the concealed door handle 10 and the door 201 to avoid the door 201 from obstructing the normal ejection of the door handle 10. However, the gap between the door handle 10 and the vehicle door 201 tends to store moisture, and may also frost in cold weather, thereby preventing the door handle 10 from being normally ejected. The heating element 20 is disposed at the opening and closing position of the door handle 10 according to the embodiment of the present invention, and the heating element 20 can generate heat and transmit the heat to the door handle 10, so that the frost on the door handle 10 is gradually melted, and the door handle 10 can be ejected normally.

In the embodiment of the present application, the heating mode and the heating start mode of the heating element 20 are not limited and may be satisfied. In one embodiment, the heating element 20 may be preset to a one minute heating period, and the heating element 20 begins to heat the door handle 10 when the door handle 10 fails to eject normally. After one minute of heating, door handle 10 will try to eject again, heating element 20 will continue to heat for one minute if ejection is not possible, then door handle 10 will try to eject again, and so on, creating a cycle until the frost is completely melted and door handle 10 will eject normally.

In another embodiment, the user may also control the heating element 20 to heat the door handle 10 by himself or herself with a car key or other smart terminal, so that the door handle 10 may be heated to a set temperature. For example, the smart terminal of the user may be a smart phone of the user, the user may connect to the automobile through the smart phone indoors to control the automobile to heat the door handle 10, and the user may normally pop up through the smart phone door handle 10 after approaching the automobile. The user can also hold the car key to be close to the car, makes car key and car pass through bluetooth connection, and the user is giving the instruction to the car through the car key and makes the car heat door handle 10.

In some embodiments, the heating element 20 may increase the heating power and decrease the duration of heating to reduce the waiting time of the user and avoid the problem of long waiting time.

In some embodiments, the vehicle door handle device 100 may further include an ultrasonic device, and the ultrasonic device may emit a sound having the same frequency as that of the frost, so that the frost and the ultrasonic device resonate with each other, thereby performing an ice breaking function. In other embodiments, the vehicle door handle device 100 may further include a mechanical device that breaks frost by mechanical movement to achieve the effect of breaking ice.

Referring to fig. 1, in some embodiments, the heating element 20 includes a first heating element 21, the first heating element 21 wraps the door handle 10, the first heating element 21 includes a first heating wire 211 and a first protection layer 212, the first heating wire 211 is accommodated in the first protection layer 212, and the first protection layer 212 wraps the door handle 10.

Thus, the first heating wire 211 can convert the electric energy into heat energy, and the first protection layer 212 can protect the first heating wire 211 to prevent the current of the first heating wire 211 from being directed to other elements. The first protection layer 212 wraps the door handle 10 so that heat energy generated by the first heating wire 211 can be transferred to the door handle 10, so that frost on the door handle 10 is ablated.

It is understood that the first heating wire 211 and the door handle 10 are not in direct contact, and there is a material that can insulate and conduct heat, i.e., the first protective layer 212, between the two. The first heating wire 211 is received in the first protection layer 212 and the first protection layer 212 wraps the door handle 10, so that the first protection layer 212 can also conduct heat as a heat conducting element. In this way, it is possible to further improve safety, ensure that heat generated by the first heating wire 211 can be smoothly conducted to the door handle 10 through the first protective layer 212, melt frost on the door handle 10, and ensure that current is not directed to other components.

Referring to fig. 2 and 3, in some embodiments, the door handle 10 includes an end surface 11 and a side surface 12 connecting the end surface 11, and the first heating element 21 is wrapped around the side surface 12.

In this manner, the first heating element 21 may directly heat the gap between the door handle 10 and the vehicle door 201, so that frost in the gap may be ablated, thereby allowing the door handle 10 to be normally ejected.

Specifically, the side 12 of the door handle 10 forms a gap with the vehicle door 201, and the first heating element 21 is wrapped around the side 12, that is, the first heating element 21 is disposed in the gap and wraps the door handle 10 from the side 12. The side 12 of the door handle 10 has the largest contact area with the vehicle door 201, and the first heating element 21 can directly heat the gap, so that the frost existing at the gap is melted, and the door handle 10 can be normally extended.

Referring to fig. 1, in some embodiments, the vehicle door handle device 100 further includes a first temperature sensor 30, and the first temperature sensor 30 is disposed near the first heating element 21 for detecting the temperature of the first heating element 21.

Thus, the first temperature sensor 30 may be disposed near the first heating element 21 to detect the temperature of the first heating element 21, and then control the on state of the first heating element 21 according to the detected temperature to avoid the first heating element 21 being turned on for a long time, thereby saving energy.

Specifically, the first temperature sensor 30 may be a non-contact temperature sensor, and may also be a temperature sensor that is in direct contact with the first heating element 21 to detect the temperature of the door handle 10. The first temperature sensor 30 may be set to detect every 10 seconds, and the vehicle system controls the first heating element 21 to heat the door handle 10 when the door handle 10 cannot be ejected and the first temperature sensor 30 detects that the temperature of the door handle 10 does not reach the set temperature. During this period, the first temperature sensor 30 continuously detects that the temperature of the door handle 10 does not reach the set temperature, and controls the first heating element 21 to increase the heating power. The set temperature is a temperature at which frost on the door handle 10 can be melted, and when the first temperature sensor 30 detects that the temperature of the door handle 10 reaches the set temperature, the first heating element 21 stops heating, and the door handle 10 is normally ejected. In this way, the heating power of the first heating element 21 can also be determined for specific weather conditions, in the manner that the first temperature sensor 30 continuously detects. It is also possible to avoid the first heating element 21 heating the door handle 10 for a long time, resulting in an excessive temperature of the door handle 10 and a waste of energy.

It is understood that, referring to fig. 4, the vehicle 200 further includes a controller 202, and the first temperature sensor 30 and the first heating element 21 may be electrically connected to the controller 202, such that the first temperature sensor 30 can transmit the detected temperature data back to the controller 202, and the controller 202 can turn on or off the first heating element 21 according to the detected data value, and can also adjust the power of the first heating element 21.

In some embodiments, when the first temperature sensor 30 detects that the temperature of the door handle 10 is low, the first heating element 21 may directly increase the heating power, and reduce the duration of heating, so as to reduce the waiting time of the user and avoid the problem of long waiting time of the user.

Referring to fig. 1 to 3, in some embodiments, the vehicle door handle device 100 further includes a catcher piece 40, and the door handle 10 is movably mounted on the catcher piece 40.

In this way, the door handle 10 is movably mounted on the catcher piece 40, so that the catcher piece 40 can also drive the door handle 10 to move, ensuring the normal ejection of the door handle 10.

Specifically, the door handle 10 is movably mounted on the catcher piece 40, and a motor may be disposed in the catcher piece 40 so that the door handle 10 may move relative to the catcher piece 40, thereby enabling the door handle 10 to be extended or ejected from the vehicle door 201. The door handle 10 may have a long bar shape, the door handle 10 may include a first end 13 and a second end 14, and a user may hold the door handle 10 or pull the door handle 10 by the end of the door handle 10 to open the vehicle door 201.

For example, the door handle 10 may be rotatably disposed with respect to the vehicle door 201, the first end 13 may be connected to a motor inside the handle member 40, the motor may be connected to the first end 13 through a gear structure, the motor provides a torque, and the second end 14 may be rotated with respect to the first end 13 such that the second end 14 is rotated out of the vehicle door 201. The concealed door handle 10 is formed with the second end 14 embedded in the catcher piece 40 at ordinary times, with a gap between the second end 14 and the catcher piece 40. So, make the whole more pleasing to the eye of car on the one hand, on the other hand can make automobile body lines more smooth, helps reducing the windage, increases car duration.

In some embodiments, the door handle 10 may be disposed to translate relative to the vehicle door 201, and the first end 13 and the second end 14 may be connected to a motor inside the catcher piece 40 at the same time, and the motor drives the first end 13 and the second end 14 to move outwards relative to the vehicle door 201 to eject. During ejection, the first end portion 13 and the second end portion 14 are simultaneously connected to the vehicle door 201, and a portion in the middle of the first end portion 13 and the second end portion 14 is not connected, so that there is enough space to accommodate the user's hand. The hidden door handle 10 is formed by embedding the first end part 13 and the second end part 14 into the vehicle door 201 in normal times. It will be appreciated that the motor and door handle 10 may have a transmission for converting rotational motion generated by the motor into translational motion of the door handle 10.

In the present embodiment, the connection mode of the door handle 10 and the catcher 40 and the movement state of the door handle 10 with respect to the vehicle door 201 are not limited and may be satisfied as required.

Referring to fig. 1 to 3, in some embodiments, the catcher piece 40 has a receiving groove 41, and the door handle 10 can be received in the receiving groove 41.

As such, the door handle 10 is accommodated in the accommodating groove 41 such that the door handle 10 is retracted into the vehicle door 201, and the door handle 10 may also be ejected from the accommodating groove 41 such that the user can open the vehicle door 201 by holding the door handle 10 with his hand.

Specifically, the catcher member 40 is provided in the vehicle door 201, and when the door handle 10 is retracted into the accommodating groove 41, the end surface 11 of the door handle 10 tends to be flush with the outer surface of the vehicle door 201, so that the door handle 10 can be hidden in the vehicle door 201. Therefore, the lines of the vehicle body are smoother, the wind resistance is reduced, and the cruising ability of the vehicle 200 is improved. The door handle 10 may protrude from the vehicle door 201 when the door handle 10 is ejected. The space between the side surface 12 of the door handle 10 and the receiving groove 41 is a gap.

Referring to fig. 1 to 3, in some embodiments, the heating element 20 further includes a second heating element 22, and the second heating element 22 is mounted on an inner wall of the accommodating groove 41.

In this manner, the second heating element 22 may directly heat the gap between the door handle 10 and the receiving slot 41, such that frost in the gap may be ablated, thereby allowing the door handle 10 to be normally ejected from the receiving slot 41.

It will be appreciated that in the present embodiment, when the heating element 20 is functionally activated, it is preferred that the first heating element 21 and the second heating element 22 are activated simultaneously so that the frost in the gap can be quickly ablated to avoid the user waiting too long. The temperature sensor can avoid detecting the temperature at any time and avoid overheating the first heating element 21 and the second heating element 22, so that the door handle 10 is hot. Of course, in some embodiments, it is also possible to activate only the first heating element 21 or only the second heating element 22 to heat the frost on the inner wall of the container 41.

Illustratively, when the gap frost is severely frozen, the second heating elements 22 provided on the inner walls of the container 41 are activated to heat the melting frost. In one embodiment, when the temperature sensor detects a low temperature, it may be that the first heating element 21 and the second heating element 22 are activated simultaneously to heat the entire vehicle door handle apparatus 100, ensuring that the heating power may cause the frost to be ablated. At this time, the temperature sensor can detect the temperature, and the temperature is prevented from being too high. In another example, the first heating element 21 may be heated in advance, and when the temperature sensor detects that the temperature cannot return, the second heating element 22 is activated again to heat the frost in the gap. Of course, in other embodiments, it is also possible to activate only the second heating element 22 to heat the frost on the inner wall of the container 41.

Referring to fig. 1, in some embodiments, the second heating element 22 includes a second heating wire 221 and a second protection layer 222, the second heating wire 221 is contained in the second protection layer 222, and the second protection layer 222 is attached to the inner wall of the containing groove 41.

Thus, the second heating wire 221 can convert the electric energy into heat energy, and the second protection layer 222 can protect the second heating wire 221 from the current of the second heating wire 221 being directed to other elements. The second protective layer 222 wraps the door handle 10 so that heat energy generated by the second heating wire 221 can be transferred to the door handle 10, so that frost on the door handle 10 is ablated.

It can be understood that the second heating wire 221 is not in direct contact with the receiving groove 41, and a material capable of conducting heat and electricity, i.e., the second protection layer 222, is disposed therebetween. The second heating wire 221 is accommodated in the second protection layer 222 and attached to the inner wall of the accommodating groove 41, so that the second protection layer 222 can also serve as a heat conducting element to conduct heat. In this way, it is possible to further improve safety, ensure that heat generated from the second heating wire 221 can be smoothly conducted to the gap between the door handle 10 and the receiving groove 41 through the second protective layer 222, melt frost in the gap, and ensure that current is not directed to other components.

Referring to fig. 1, in some embodiments, the vehicle door handle device 100 further includes a second temperature sensor 50, and the second temperature sensor 50 is disposed near the second heating element 22 for detecting the temperature of the second heating element 22.

Thus, the second temperature sensor 50 can be disposed near the second heating element 22 to detect the temperature of the second heating element 22, and then control the on state of the second heating element 22 according to the detected temperature to avoid the second heating element 22 being turned on for a long time, thereby saving energy.

Specifically, the second temperature sensor 50 may be a non-contact type temperature sensor, and may also be a temperature sensor that is in direct contact with the second heating element 22 to detect the temperature of the gap between the door handle 10 and the receiving groove 41. The second temperature sensor 50 and the first temperature sensor 30 may be used simultaneously or even one of them may be turned on.

Illustratively, the first temperature sensor 30 is used to detect the temperature of the first heating element 21, while the second temperature sensor 50 is used to detect the temperature of the second heating element 22. The two temperature sensors can transmit the detected data back to the controller 202 of the vehicle, the controller 202 simultaneously connecting the first heating element 21 and the second heating element 22 and the temperature sensors of the vehicle itself. Controller 202 may also be coupled to interface element 40 to detect whether door handle 10 is extended.

In one example, controller 202 detects that door handle 10 cannot be extended normally, first temperature sensor 30 and second temperature sensor 50 detect that the temperatures of first heating element 21 and second heating element 22, respectively, are both less than 40 ℃, and transmit data back to controller 202, while controller 202 detects that the ambient temperature outside the vehicle is less than 5 ℃. At this point, the controller 202 may control the first and second heating elements 21 and 22 to activate to heat the frost in the ablation gap.

In the present embodiment, the kind of the temperature sensor is not limited, and the first temperature sensor 30 and the second temperature sensor 50 may be contact type temperature sensors, for example, a pressure type thermometer, a resistance thermometer, a thermistor, a thermocouple, and the like; it is also possible to use a contactless temperature sensor, for example an infrared thermometer or the like, to meet different requirements.
