A car with an auxiliary door opening and closing device

Abstract

The invention discloses an automobile with an auxiliary door opening and closing device. The automobile comprises an automobile body and a plurality of automobile doors arranged on the automobile door. At least one automobile door is provided with the auxiliary door opening and closing device. The auxiliary door opening and closing device comprises an angle sensing device, a control system and a door rotating device. The control system outputs power to the door rotating device according to an input control power source of sensing signals so that the spin moment of the corresponding automobile door can be resisted. The auxiliary door opening and closing device further comprises a clutch mechanism. Whether the difference value between the door inclination angle and ninety degree is located in a preset range or not is judged by the control system; if yes, the control system controls the clutch mechanism to be located in an off position; and if no, the control system controls the clutch mechanism to be located in a closed position. The automobile has the following advantages that the influence of the rotating moment generated by the self-gravity of the automobile door to opening and closing of the automobile door is small when the automobile is in various parking states, and the connection relations between the automobile door and the door rotating device can be determined according to occasions.

Description

technical field [0001] The invention relates to the field of automobile manufacturing. Background technique [0002] Cars are an important means of transportation in daily life, but common cars have a common disadvantage. When the car is parked on a slope, it will bring great inconvenience to the opening and closing of the door. The application number I applied for before is 201510043947.5 The Chinese patent has made beneficial improvements, providing a car with an auxiliary door opening and closing device, including a car base, a power supply arranged on the car base, and a number of doors arranged on the car base; wherein at least one door is equipped with an auxiliary switch Door device, auxiliary door switch device includes: angle sensing device, control system, revolving door device; The input control system; the revolving door device obtains power from the power supply to generate the torque for turning the door; the control system controls the power supply to output ...

AI Technical Summary

Problems solved by technology

But above-mentioned two kinds of technical schemes have a common deficiency, specifically as follows: in most cases, automobile is all parked on substantially level road surface, and the situation that automobile parks on inclined road surface just happens occasionally, and when automobile is parked on level road surface, The inclination angle of the door is about 90 degrees, and the rotational torque generated by the door under the action of gravity is zero, that is, the revolving door device is not needed to provide assistance, and the revolving door device that forms a connection relationship with the car door brings inconvenience to the opening and closing of the car door, so there is a It is necessary to further improve the above-mentioned technical scheme, so that the connection relationship between the car door and the revolving door device can be randomly determined
