Novel automobile electric handle

Abstract

A novel automobile electric handle comprises a handle body, a handle base, a driving mechanism, a transmission cam, a conversion arm and an unlocking arm, wherein the handle body at least has an initial hidden state in which the handle body retracts into an automobile door, a pre-unfolding state in which the handle body stretches out of the automobile door and a complete opening state when the automobile door is opened; a handle main body is mounted in the handle base; the driving mechanism is used for providing driving force; the transmission cam is rotationally connected with the handle baseand is driven by the driving mechanism; the conversion arm is rotationally connected with the handle base, is in transmission connection with the handle main body, is further in contact connection with the transmission cam and can be driven by the transmission cam; the unlocking arm is used for realizing an unlocking function of the automobile door lock; and the side, close to the conversion arm,of the transmission cam is provided with a guide track curved surface which is in contactable connection with the conversion arm. A transmission combined structure composed of the transmission cam, the conversion arm and the unlocking arm is adopted, the number of parts is reduced, the cost is reduced, and the product reliability is improved.

Description

technical field [0001] The invention relates to the technical field of automobile parts, in particular to a novel automobile electric handle. Background technique [0002] At present, the door handles of most automobiles are exposed and convex. On the one hand, the design needs to consider that the shape of the door handle needs to match the side of the car body to ensure a good appearance, which causes many limitations; on the other hand, Since the outer door handle is exposed as a whole, the inner and outer sides of the outer door handle are easily polluted, and the driver's hand is easy to get dirty when opening the door. Moreover, the door handle protrudes outward, which not only damages the appearance of the side of the vehicle, but also creates a certain amount of wind resistance, which increases the driving resistance of the vehicle and increases wind noise. For this reason, many manufacturers have improved the handle structure and produced retractable hidden handles...

AI Technical Summary

Problems solved by technology

For example: 1. The electric structure is complex, there are many parts and components, the cost is high, the product reliability is low, and under the limitation of the structure, it makes assembly difficult, and the failure rate is high in actual use, resulting in a decrease in the overall reliability of the handle; 2. The current The retractable hidden handle has many openings due to the large number of parts, resulting in poor airtightness of the handle; 3. The current hidden handle generally has three positions, that is, retracted to the initial position in the door. In the hidden state, the pre-deployed state protruding out of the door, and the fully opened state when the door is opened, the handle body is generally switched from the initial hidden state to the pre-deployed state through an electric actuator or manually. At this time, the user continues to pull the handle body It can be switched to the fully open state, thereby unlocking the door lock and opening the car door; but in the pre-deployed state, due to the function of the reset component, the handle body always has a tendency to retract, which may cause hand pinching if not careful , so there is an urgent need for a state holding structure to prevent the handle body from retracting
