Automobile provided with auxiliary door opening and closing device

Abstract

The invention discloses an automobile provided with an auxiliary door opening and closing device. The automobile comprises an automobile base body, a power source and automobile doors. 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 induction device, a control system and a door rotating device. The angle induction device is used for inducting the inclination angles of the doors and inputting induction signals into the control system. A detecting unit is further included and used for detecting the stroke position of the door rotating device and inputting the stroke position into the control system. The control system controls the power source to output electric power to the door rotating device according to the inclination angles of the doors and the stroke position of the door rotating device to resist the spin moment of the automobile doors. The automobile has the following beneficial effects that when the automobile is in various parking states, the influence of driving torque generated by the self gravity of the automobile doors on opening and closing of the automobile doors is small; and by means of the door rotating device, a higher freedom degree is achieved so that the aim of matching the auxiliary door opening and closing device with space in the automobile can be achieved.

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, disclosing 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; the door rotates around the door axis to realize the door The door axis refers to the straight line running through the core of the door shaft. The plane passing through the door axis and the center of gravity of the door is called the door plane. The rotational moment generated by the door under the action of its own gravity is called the rotation moment. The ...

Problems solved by technology

However, this technology still has its insurmountable shortcomings: the scheme limits the setting of the revolving door device, that is, the rotational torque generated by the revolving door device on the car door has nothing to do with the operating stroke of the revolving door device, so that the revolving door device is set As we all know, the installation of the revolving door device in the car body should be determined according to the internal mechanism of the car body. The setting of the door device has a relatively large selection surface, in view of this, the above-mentioned technical scheme must be further supplemented
