Electric opening device for vehicle door

Abstract

The invention provides a vehicle door electric opening device which comprises an electric supporting rod, a sliding mechanism, a connecting rod mechanism and a control unit, the sliding mechanism comprises a sliding rail and a sliding block limited in the sliding rail and capable of sliding along the sliding rail, the telescopic end of the electric supporting rod is fixedly connected with the sliding block, one end of the connecting rod mechanism is hinged to a vehicle door, and the other end of the connecting rod mechanism is hinged to the sliding block. The two ends of the connecting rod mechanism can rotate around the corresponding hinge points respectively, the electric supporting rod is fixed to the lower portion of the outer side of the threshold, the control unit controls the electric supporting rod to stretch out and draw back, and the electric supporting rod stretches out and draws back to drive the sliding block to slide along the sliding rail and the connecting rod mechanism to rotate around the hinge points to open or close the automobile door. According to the electric opening device for the vehicle door, the electric supporting rod is adopted, an electric limiting stopper is omitted, the product cost is reduced, the overall structure is simple, the operation stability is good, the failure rate is low, arrangement of other vehicle door components is facilitated, the modeling freedom degree is better, and the collision resistance of a vehicle body is higher.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an electric door opening device. Background technique [0002] With the rise of new energy vehicles and consumers' increasingly high requirements for intelligent vehicle configuration, the use of electric doors for mid-to-high-end models in the market has become the mainstream configuration. At present, the opening method of electric vehicle doors on the market usually adopts the cooperation method of electric limiter and electric pull-in lock. Because the electric limiter itself is relatively large in size and weight, it cannot be installed outside the door, and needs to be hidden in the door cavity, so it takes up a lot of the interior space of the door cavity, increasing the door opening and other accessories of the door (such as glass It is difficult to arrange the guide rails), which will seriously affect the visual appearance of the door. In addition, there are few man...

Problems solved by technology

Since the volume and weight of the electric limiter itself are relatively large, it cannot be installed outside the door, but needs to be hidden in the door cavity of the car door, so it takes up a lot of space inside the door cavity of the car door, and the door opening and other accessories of the car door (such as glass) are added. Guide rail) is difficult to arrange, and even seriously affects the visual appearance of the door; in addition, there are few manufacturers of electric stoppers and the prices are relatively expensive. All vehicle doors are equipped with electric stoppers, which will inevitably increase the cost of the vehicle
