For hand holding, when the vehicle door is closed, at least part of the outer surface of the handle 12 can be flush with the first surface 111 and the outer surface of the vehicle door, which can reduce the wind resistance of the vehicle during driving and improve the appearance quality of the entire vehicle; the heating device 13 can be arranged in the accommodating cavity 12a of the handle 12, the heating element 131 can heat the heat transfer element 132, and the heat transfer element 132 can contact and exchange heat with the handle 12, so that the handle 12 can obtain heat and achieve heating and temperature rise. At the same time, the heat transfer element 132 is constructed as a graphene material piece, which can improve the heat conduction efficiency, heating uniformity and stability, and is beneficial to saving energy consumption.

[0048] It should be pointed out that the above-mentioned base 11 can form a accommodating cavity suitable for accommodating the handle 12, and the accommodating cavity is open toward the first surface 111. When the handle 12 is completely accommodated in the accommodating cavity, the handle 12 closes the accommodating cavity, and the side of the handle 12 facing away from the cockpit is flush with the first surface 111, so as to ensure the flatness and consistency with the outer surface of the vehicle door.

[0049] According to the vehicle door handle assembly 1 of the utility model, the heating efficiency and heating uniformity of the handle 12 can be improved, so as to save the time of heating and thawing the handle 12, improve the comfort of holding the handle 12, and effectively improve the user experience. At the same time, since the heating device 13 is arranged in the accommodating cavity 12a of the handle 12, the heating device 13 can be installed on the base 11 through the handle 12, which can improve the convenience of assembling the heating device 13. Moreover, the heating device 13 is hidden in the accommodating cavity 12a, which can also reduce the possibility of contact with external rain, dust, etc., which can increase the service life and save maintenance costs.

[0050] In addition, if Figure 2 As shown, in some specific embodiments of the present invention, the heating device 13 and the handle 12 are fixedly connected by a fixing glue 15 to ensure good connection stability between the heating device 13 and the handle 12 and save costs.

[0057] like Figure 2 and Figure 3 As shown, according to some embodiments of the present invention, the heating element 131 is disposed in the heat transfer element 132 , and the extending direction of the heating element 131 and the heat transfer element 132 is consistent with the extending direction of the handle portion 1212 .

[0058] Specifically, in this embodiment, the heating element 131 can be arranged inside the heat transfer element 132, and the heat transfer element 132 covers the outside of the heating element 131. The heat transfer element 132 has high thermal conductivity and thermal conductivity uniformity, which can improve the efficiency of the heating element 131 in transferring heat to the handle 12, achieve rapid heating and thawing of the handle 12, and increase the uniformity of temperature rise in various areas of the handle 12, thereby avoiding local excessive temperature, thereby improving the comfort of the user when holding the handle 12. In addition, the extension direction of the heating element 131 and the heat transfer element 132 can be consistent with the extension direction of the handle portion 1212. In this way, on the one hand, the shapes of the heating element 131 and the heat transfer element 132 are adapted to the handle portion 1212, which can ensure that each area of ​​the handle portion 1212 has a good heating effect; on the other hand, by setting the extension direction of the heating element 131 and the heat transfer element 132 to be consistent with the extension direction of the handle portion 1212, the shapes of the heating element 131 and the heat transfer element 132 can also be made regular, which is beneficial to improving the manufacturing convenience of the heating element 131 and the heat transfer element 132 and improving production efficiency.

[0059] like Figure 2 and Figure 3 As shown, according to some embodiments of the present invention, the heating element 131 is disposed in the heat transfer element 132, and at least a portion of the heating element 131 and the heat transfer element 132 is consistent with the extension direction of the handle portion 1212, and at least another portion of the heating element 131 and the heat transfer element 132 is consistent with the extension direction of the connecting portion 1211.

[0060] Specifically, in this embodiment, the heating element 131 can be arranged inside the heat transfer element 132, and the heat transfer element 132 covers the outside of the heating element 131. Similarly, the heat transfer element 132 has high thermal conductivity and thermal conductivity uniformity, which can improve the efficiency of the heating element 131 in transferring heat to the handle 12, achieve rapid heating and thawing of the handle 12, and increase the uniformity of temperature rise in various areas of the handle 12, thereby avoiding excessive local temperature, thereby improving the comfort of the user when holding the handle 12. In addition, in the present embodiment, at least a portion of the heating element 131 and the heat transfer element 132 is consistent with the extension direction of the handle portion 1212, and at least a portion of the heating element 131 and the heat transfer element 132 can be accommodated in the accommodating cavity 12a area corresponding to the handle portion 1212, and at least another portion of the heating element 131 and the heat transfer element 132 is consistent with the extension direction of the connecting portion 1211, and at least another portion of the heating element 131 and the heat transfer element 132 can be accommodated in the accommodating cavity 12a area corresponding to the connecting portion 1211, so that the shape of the heating element 131 and the heat transfer element 132 is the same as the assembled shape contour of the handle portion 1212 and the connecting portion 1211, so as to significantly increase the contact heat exchange area between the heating device 13 and the handle 12, thereby enhancing the heating and thawing effect.

[0061] like Figure 3 As shown, according to some embodiments of the present invention, a terminal 1311 is provided at the end of the heating element 131 , and at least a portion of the terminal 1311 is located outside the heat transfer element 132 and is suitable for connection to a power source.

[0062] Specifically, a terminal 1311 may be provided at one end of the heating element 131 in the extension direction, and at least a portion of the terminal 1311 is located outside the heat transfer element 132 so as to be connected to a power source. After the terminal 1311 is connected to a power source (such as a vehicle-mounted power source), the heating element 131 may be powered on to generate heat, thereby ensuring the heating and temperature rise of the handle 12. A wire may be arranged between the terminal 1311 and the power source to achieve electrical connection, one end of the wire is connected to the terminal 1311, and the other end may pass through the connecting portion 1211 and extend to the base 11 so as to be connected to a power source to receive power from the vehicle-mounted power source and achieve the heating function.

[0063] like Figure 1 As shown, according to some embodiments of the present invention, the vehicle door handle assembly 1 further includes a controller, which is electrically connected to the heating device 13 and is suitable for controlling the heating device 13 to heat the handle 12 .

[0064] Specifically, the controller can be electrically connected to the heating device 13, and the controller can receive signals from the temperature sensor on the vehicle, as well as identify weather information and the temperature and humidity outside the vehicle. When the controller receives the signal and obtains information that the handle 12 needs to be heated, the heating device 13 can be controlled to heat the handle 12 to thaw and heat it to a comfortable holding temperature, so as to ensure that the driver and passengers can easily open the door and have a comfortable experience. The controller can also receive the handle 12 temperature signal, heating time signal, and manual stop heating signal. After the handle 12 reaches the set temperature or time, the heating device 13 is turned off, and the controller can control the heating device 13 to stop heating, so as to save energy and improve safety.

[0065] It should be pointed out that the manual stop heating signal can be a remote signal outside the vehicle, such as a remote control, etc. The manual stop heating signal can also be sent as a signal inside the vehicle. For example, the display screen inside the vehicle can be provided with a stop heating identification button that interacts with the controller so that deicing and defrosting can be controlled inside the vehicle.

[0066] In addition, if Figure 4 As shown, in some specific embodiments of the present invention, a control method for a door handle assembly 1 is proposed, including: obtaining a vehicle remote start signal; the controller is started, and weather information and the outside temperature of the vehicle are obtained; when the outside temperature of the vehicle is lower than a preset temperature threshold, the controller starts the heating device 13 to heat the handle 12; when the outside temperature of the vehicle is greater than or equal to the preset temperature threshold, the controller does not start the heating device 13. In this way, by combining the door handle assembly 1 with the vehicle remote start function, the heating intelligence of the handle 12 can be improved.

[0067] It should be pointed out that the above-mentioned preset temperature threshold can be formulated according to the needs of the car owner. For example, when the outdoor temperature is below 5°C, the vehicle can be remotely started to heat the interior of the car while also heating the external handle 12. This can also avoid the problem of icy hands when opening the car door at low temperatures, and can further improve the comfort of vehicle use.

[0068] like Figure 5 As shown, in some other specific embodiments of the present invention, the control method for the door handle assembly 1 includes: obtaining an unlock signal; starting the controller; the controller controls the heating device 13 to heat. The unlock signal can be sent by the remote control button and the handle 12, and the controller can force the heating device 13 to start after receiving the unlock signal to heat the handle 12. The control method for the door handle assembly 1 of this embodiment can be applied to vehicles without remote start or outdoor temperature sensors, and can also be used in emergency situations.

[0069] It should be pointed out that the above unlocking signal can be set with a triggering logic. For example, it can be set to repeatedly operate the unlocking button more than twice within one second to turn on the heating device 13. After the handle 12 reaches the set temperature or time, it can be fed back to the controller to turn off the heating device 13 and stop heating.

[0070] like Figure 2 As shown, according to some embodiments of the present invention, the vehicle door handle assembly 1 further includes: a sensing antenna 14, which is electrically connected to the controller and is suitable for sending the received opening signal to the controller.

[0071] Specifically, the sensing antenna 14 can be electrically connected to the controller, and the sensing antenna 14 can receive an opening signal from a remote control unit (such as a smart key or a mobile phone, etc.), and send the opening signal to the controller, so that the controller can control the remote unlocking, locking, and starting of the vehicle, etc., which can improve the convenience, safety, and user experience of the vehicle. In addition, the sensing antenna 14 can be arranged in the accommodating cavity 12a, and the wiring harness of the sensing antenna 14 and the heating device 13 can be integrated into one and electrically connected to the controller, so that the integration can be improved and the space utilization rate can be improved.

[0072] like Figure 1-Figure 5 As shown, according to the vehicle door of the second embodiment of the utility model, the vehicle door comprises: the vehicle door handle assembly 1 described in any one of the above embodiments. Since the vehicle door according to the second embodiment of the utility model is provided with the vehicle door handle assembly 1 described in any one of the above embodiments, the vehicle door has the function of heating the handle 12, and the heating efficiency is high and the heating is uniform, which can save the time of heating and thawing the handle 12, and improve the comfort of holding the handle 12, so as to effectively improve the user experience.
