[0025] like Figure 1 As shown, an embodiment of this application provides a door handle assembly 100, which is mainly used on vehicle doors. The door handle assembly 100 includes a base 110, a handle member 120, a support member 130, a seal member 140, a heating member 150, and a controller (not shown).

[0026] A first slot 111 is formed on one side of the base 110. The handle 120 is disposed in the first slot 111 and rotatably connected to the base 110. A support 130 is disposed in the first slot 111 and located circumferentially to the handle 120. A second slot 131 is formed on the side of the support 130 opposite to the base 110. A sealing element 140 is disposed in the second slot 131 and located circumferentially to the handle 120, for abutting against the door sheet metal part 200. A heating element 150 is disposed between the groove wall of the second slot 131 and the sealing element 140. The controller is electrically connected to the heating element 150.

[0027] The door handle assembly 100 provided in the embodiments of this application has a first slot 111 on one side of the base 110, a handle 120 disposed in the first slot 111 and rotatably connected to the base 110, a support 130 disposed in the first slot 111 and located circumferentially to the handle 120, a second slot 131 on the side of the support 130 away from the base 110, and a sealing member 140 disposed in the second slot 131 and located circumferentially to the handle 120. By abutting the sealing member 140 against the door sheet metal 200, the gap between the door sheet metal 200 and the base 110 is sealed, thereby preventing dust and rainwater from entering the interior of the door.

[0028] Meanwhile, by setting a heating element 150 between the groove wall of the second card slot 131 and the seal 140, and electrically connecting the heating element 150 to the controller, the controller can control the heating element 150 to turn on or off heating. In this way, when the heating element 150 turns on, it can quickly melt the ice layer 300, avoiding the technical problem that the handle cannot be ejected due to the ice layer, causing the door to remain unopenable after unlocking.

[0029] For example, the support member 130 can be made of hard plastic, and the seal member 140 can be made of soft plastic. The heating element 150 can be a heating mesh formed by combining multiple resistance wires, and the controller can be a programmable controller.

[0030] In one embodiment of this application, the door handle assembly 100 further includes a power source (not shown), and the controller is electrically connected to both the power source and the heating element 150.

[0031] Thus, the controller and heating element 150 are powered by the power supply.

[0032] For example, the power source can be a secondary battery disposed on the door handle assembly 100, or it can be a power source for the vehicle's power supply system.

[0033] In one embodiment of this application, the door handle assembly 100 further includes a temperature detection sensor (not shown), which is electrically connected to the controller and is used to detect the temperature of the external environment.

[0034] In this embodiment, a temperature detection sensor electrically connected to the controller is used to detect the temperature of the external environment. When the temperature of the external environment is lower than a preset value, the controller can control the heating element 150 to automatically turn on the heating based on the signal fed back by the temperature detection sensor, thereby realizing the function of preventing the door handle assembly 100 from freezing in advance.

[0035] In one embodiment of this application, the controller is provided with a wireless communication module (not shown), which is used for wireless communication connection with a terminal device.

[0036] In this embodiment, the controller is equipped with a wireless communication module for wireless communication connection with the terminal device, which enables the user to send control commands to the controller by operating the terminal device, so that the controller controls the heating element 150 to turn on or off heating according to the control commands.

[0037] For example, the terminal device can be a car key with a physical switch button. The user sends a control command to the controller by pressing the physical switch button, causing the heating element 150 to turn on or off. The terminal device can also be a mobile phone, where the user sends a control command to the controller by clicking the switch button in the mobile phone's APP, causing the heating element 150 to turn on or off.

[0038] In one embodiment of this application, the door handle assembly 100 further includes a wireless receiver (not shown), which is electrically connected to the controller and is used for wireless communication with the wireless transmitter of the terminal device.

[0039] In this embodiment, by wirelessly connecting the wireless receiver to the wireless transmitter of the terminal device and electrically connecting the wireless receiver to the controller, when the user's terminal device approaches the door handle assembly 100, the wireless receiver can receive the signal emitted by the wireless transmitter and feed the signal back to the controller. The controller controls the heating element 150 to automatically turn on the heating according to the signal fed back by the wireless receiver, thereby realizing the function of the heating element 150 automatically turning on the heating when the user approaches the door handle assembly 100.

[0040] In any of the above embodiments of this application, the sealing element 140 is integrally molded from soft rubber and insulating and thermally conductive material. This not only achieves the sealing performance of the sealing element 140, but also improves the thermal conductivity of the sealing element 140 under the action of the insulating and thermally conductive material, thereby facilitating the transfer of heat generated by the heating element 150 to the ice layer 300 and improving the melting efficiency of the ice layer 300.

[0041] For example, the soft adhesive can be rubber or silicone, and the insulating and thermally conductive material can be graphene.

[0042] In any of the above embodiments of this application, the heating element 150 is provided with a first adhesive layer (not shown) on the side of the groove wall of the second slot 131 near the groove wall, and the heating element 150 is bonded to the groove wall of the second slot 131 through the first adhesive layer.

[0043] In this embodiment, a first adhesive layer is provided on the side of the heating element 150 near the groove wall of the second groove 131, which is bonded to the groove wall of the second groove 131. Under the bonding action of the first adhesive layer, the heating element 150 is stably placed in the second groove 131, so as to avoid the heating element 150 moving in the second groove 131 and affecting its effect of heating and melting the ice layer 300.

[0044] For example, the first adhesive layer may be double-sided adhesive.

[0045] In any of the above embodiments of this application, the heating element 150 is provided with a second adhesive layer (not shown) on the side near the sealing element 140, and the heating element 150 is bonded to the sealing element 140 through the second adhesive layer.

[0046] In this embodiment, a second adhesive layer is provided on the side of the heating element 150 near the sealing element 140, which is bonded to the sealing element 140. Under the bonding action of the second adhesive layer, the heating element 150 and the sealing element 140 are kept in close contact, thereby ensuring heat transfer efficiency and thus ensuring the effect of the heating element 150 in heating and melting the ice layer 300.

[0047] For example, the second adhesive layer may be double-sided adhesive.

[0048] In any of the above embodiments of this application, the door handle assembly 100 further includes a temperature control switch (not shown). The heating element 150 is electrically connected to the controller through the temperature control switch. This can play a role in thermal protection, preventing the heating element 150 from overheating and melting the sealing element 140 and the support element 130. On the other hand, it can also save energy.

[0049] This application also provides a vehicle door, including the door handle assembly 100 described in the above embodiments.

[0050] The door has the door handle assembly 100 of any of the above embodiments, and therefore has all the beneficial effects of the door handle assembly 100, which will not be described in detail here.

[0051] This application also provides a vehicle, including the door described in the above embodiments.

[0052] The vehicle has the doors described in the above embodiments, and therefore has all the beneficial effects of doors, which will not be elaborated here.

[0053] In summary, this application proposes a door handle assembly 100, which includes a base 110, a handle 120, a support 130, a seal 140, a heating element 150, and a controller. A first slot 111 is formed on one side of the base 110. The handle 120 is disposed within the first slot 111 and rotatably connected to the base 110. The support 130 is disposed within the first slot 111 and located circumferentially to the handle 120. A second slot 131 is formed on the side of the support 130 opposite to the base 110. The seal 140 is disposed within the second slot 131 and located circumferentially to the handle 120. By abutting against the door sheet metal part 200, the gap between the door sheet metal part 200 and the base 110 is sealed, thereby preventing dust and rainwater from entering the interior of the door. Meanwhile, by setting a heating element 150 between the groove wall of the second card slot 131 and the seal 140, and electrically connecting the heating element 150 to the controller, the controller can control the heating element 150 to turn on or off heating. In this way, when the heating element 150 turns on, it can quickly melt the ice layer 300, avoiding the technical problem that the handle cannot be ejected due to the ice layer, causing the door to remain unopenable after unlocking.
