Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile door handles, in particular to an automobile door handle structure. Background Art
[0002] A car door handle is a device used to open and close the car door, usually called a door lock, door buckle or door handle. Most models on the market use a horizontal bar outward pull door handle. This design is ergonomic and allows the driver to open the door easily. There are many types of car door handles, including solid, hollow and hollow handles, which are mainly divided into two categories: horizontal pull type and lift-up type.
[0003] In the existing car door handle structure, most car door handles on the market have a reserved keyhole outside. When the remote control key is out of power, it can be opened with a mechanical key. However, when the car is driven for a long time or left unused, dust easily accumulates in the keyhole, which can be blocked when the key is inserted, making it less practical. In addition, when the door handle is pulled hard in rainy, snowy and freezing weather, the connection between the door handle and the car door lock is relatively stiff, not flexible enough when pulled, and thus less practical.

[0010] As a further description of the above technical solution: the middle part of the heating tube is fixedly installed with the support plate, and the top end of the heating tube is engaged with the fixing groove.
[0011] The utility model has the following beneficial effects:
[0012] 1. Compared with the existing technology, this automobile door handle structure movably installs the dust cover plate and the door handle body through the cooperation of the connecting pin and the mounting hole. When using the mechanical key to unlock, the card block can be pulled to lift the dust cover plate, and the mechanical key can be inserted into the keyhole to unlock. When use is completed, the keyhole is sealed by the dust cover plate to prevent the keyhole from being blocked and dust accumulation.
[0013] 2. Compared with the existing technology, this car door handle structure supports the heating tube through a support plate, uses a wire tube to transmit the wire to supply power to the heating tube, emits hot air through the heating tube, and releases the hot air to the base through the heat dissipation holes, thereby conducting heat to the connection between the base and the car door lock. When the door handle is pulled vigorously in rainy, snowy and freezing conditions, the stiffness of the connection between the door handle and the car door lock can be relieved, making it more flexible and practical when pulled.
