Aiming at the problem of difficult unlocking of the vehicle door, the existing ice breaking problem is mostly solved by increasing the torque of a handle motor and enabling an outward-opening handle to pop up through brute force. Although it is desirable to break ice by increasing the motor torque under certain conditions, the problem of difficulty in breaking ice cannot be fundamentally solved. And the bigger the motor torque is, the bigger the motor occupied space position is, the arrangement is influenced, and the requirement on the mechanism strength of the handle is higher. Meanwhile, the performance of the motor is sharply reduced in an extremely cold area, the consistency of lubricating grease is increased or the lubricating grease is solidified at low temperature, the starting torque of the motor is increased, and finally the motor is overloaded and burnt out. And excessive torque can also cause permanent damage to a transmission mechanism in the handle, so that the fit clearance of the transmission mechanism is increased, and the door is difficult to open.

In view of this, the present application is hereby presented.

Referring to fig. 1 to 3, the present embodiment relates to a vehicle (not shown) including a vehicle door 10, a vehicle power supply 30, and a door handle 20 a.

The heating module 233 may be an electric infrared heating element, a resistive heating element, or an electric heater. The resistive heating element includes, but is not limited to, a resistance wire or a heating coil.

In the door handle 20a shown in fig. 1 to 3, the heating module 233 is an electric infrared heating element, that is, ice is broken by means of infrared radiation heating. Compared with a resistance type heating mode, the heating device has higher penetrating power, can heat the inside and the outside simultaneously, and thus ensures uniform and transparent heating; heat transfer medium transmission is not needed, and the heat efficiency is good; and the temperature is easy to control, the temperature is quickly raised, and the safety is high.

It should be noted that the energy storage module 235 and the identification module 231 may be disposed outside the casing 240, respectively, but in order to ensure the compact structure, the energy storage module 235 and the identification module 231 are both accommodated in the casing 240.

In the subsequent ice breaking process, the icing sensor can be used for obtaining the heating ice breaking progress, so that the ice breaking degree can be accurately controlled.

The energy storage module 235 may be a battery, in this embodiment, the energy storage module 235 is composed of energy storage elements such as a super capacitor, and the reference parameter of the energy storage module 235 is, for example, a capacity 12F, a size: d is 12.5mm, H is 34mm, and the foot distance P is 5mm, and its characteristics are quick charging speed, reliable discharging and stable.

The heating circuit and the vehicle power supply 30 can be arranged independently or in parallel. The independent arrangement means that no circuit is connected between the heating circuit and the vehicle power supply 30.

In the door handle shown in fig. 2, the heating circuit is provided in parallel with the entire vehicle power supply 30.

When the recognition module 231 recognizes that frost is formed on the transmission mechanism 212, the controller sends a signal to the mobile phone app through the internet of vehicles to remind the owner of the occurrence of the frost on the door handle 20a of the car owner and to determine whether to perform ice breaking according to the parking place by using an ice breaking signal. If the automobile is indoor, the automobile owner can judge to directly deice because secondary icing cannot occur after the deicing; if the vehicle is parked outdoors, in order to prevent secondary icing, the vehicle owner can temporarily judge that the vehicle is not deiced according to the actual vehicle demand, and before using the vehicle, a mobile phone app is used for confirming an ice breaking signal; after the deicing is obtained, the controller starts the heating module 233 to break the ice, and the vehicle owner uses the vehicle.
