Description

Vehicle power supply covering door device

Technical Field

The utility model belongs to the technical field of automobile parts, and particularly relates to a vehicle power supply opening cover door device.

Background

The vehicle is provided with a power supply port so as to supply power to the vehicle, for example, an oil-burning vehicle needs to be filled with oil, a gas-burning vehicle needs to be inflated, an electric vehicle needs to be charged, and the like. The whole vehicle is matched with a cover door to cover the vehicle, considering the appearance of the vehicle and the sealing and safety of the power supply port.

From the view point of the whole vehicle function and safety, the cover door can not be directly opened from the outside and needs to be unlocked by vehicle interior control or a vehicle electric key. In addition, when the cover door is opened, a related warning prompt is required in the vehicle.

The common door covers on the market at present have two types of turnover type and sliding type. The sliding cover door generally realizes the parallel sliding of the small door along a certain direction through a connecting rod mechanism, and the back surface of the sliding cover door cannot be exposed, so that the sliding cover door is more attractive. But the movement of the connecting rod is more complicated and the cost is higher. Compared with the sliding type cover door, the turnover type cover door has the advantages of reliable structure and low cost, and is the most mainstream cover door form in the market at present.

For the turnover cover door, the pull wire or the motor is opened in the vehicle to unlock the door. After the above-mentioned process, the driver and passenger can make manual operation to implement opening process, and when the driver and passenger are closed, the driver and passenger also can make manual closing operation, and when the driver and passenger are closed, the driver and passenger can make locking operation by means of pull wire or motor so as to implement closing process. The vehicle power supply flap door adopting the mode has the advantages that the opening and closing processes are completed manually by a driver and a passenger except for the unlocking action, and the automation degree is low. If a driver forgets to close the cover door or the cover door is not closed or not closed in place under other conditions, the cover door is always in an open state, so that the protection and anti-theft effects cannot be achieved, and the safety hazard is relatively high. At present, although most vehicles have corresponding icons on an instrument panel to indicate the opening and closing states of the cover door, the indication effect is weak, and the situation that a driver forgets to close the cover door happens occasionally.

And a part of high-end vehicle models use an electric actuator to open and close the cover door, and although all actions of automatically opening and closing the power supply port cover door are realized, the problems that the actuator is damaged because a user easily manually operates the cover door under the influence of inertia thinking and the cover door cannot be manually opened and closed when the vehicle has circuit faults are ignored.

The utility model is realized by the following technical scheme: a vehicle power supply port covering door device comprises a door cover, a motor, a reduction gear set and a rotation sensor; the door cover is provided with a rotating shaft part, and the rotating shaft part is hinged with the vehicle body to realize that the door cover can perform overturning motion relative to the vehicle body; the motor is fixed in the vehicle body and keeps relatively static with the vehicle body; the reduction gear set is arranged between the rotating shaft part and the output shaft of the motor, and transmits the rotation of the motor to the door cover after reducing and increasing torque; at least one rotary motion member is provided in the reduction gear set, and a rotation sensor is connected to the rotary motion member and detects a rotation angle of the rotary motion member. The device uses the motor as power, drives the door closure rotation through reduction gear set, realizes opening and closing of door closure, and simultaneously, the device detects the rotation angle of a certain rotary motion spare in the reduction gear set through setting up rotation sensor to judge the door closure to the angle to the automobile body, provide the basis for automated control. In addition, in order to realize the warning function of the incompletely closed state of the cover door, the conventional vehicle needs to arrange a corresponding sensor at the cover door locking mechanism, and after the vehicle power supply cover door device is used, the warning function of the incompletely closed state of the cover door can be realized through a rotary sensor without arranging an additional sensor in the cover door locking mechanism.

Further, the rotation sensor includes a sensor body and a sensing part rotatable relative to the sensor body; the feedback signal of the rotation sensor is a voltage value or a resistance value, and the feedback data monotonously changes, preferably linearly monotonously changes, with the rotation angle of the sensing portion with respect to the sensor body. The feedback signal is a voltage value or a resistance value, and is convenient to collect, process and output through the control circuit, so that the motor is controlled. The rotation sensor may be selected according to actual needs, such as but not limited to an ALPS/Alps model RDC506002A sensor.

Further, the reduction gear set preferably uses a reduction gear set that can be driven bidirectionally. Such as the following reduction gear sets: comprises a first gear, a second gear, a third gear and a fourth gear; the first gear is fixed on an output shaft of the motor, the fourth gear is fixed on the rotating shaft part, the second gear and the third gear shaft are arranged to form a duplicate gear, the second gear is meshed with the first gear, and the third gear is meshed with the fourth gear; the number of teeth of the first gear is less than that of the fourth gear, and the number of teeth of the second gear is greater than that of the third gear.

Further, the induction part is preferably sleeved on a common rotating shaft of the second gear and the third gear, so that high control precision can be realized at low cost. If induction part is rotatory along with the motor output shaft, then will choose the rotation sensor of wide range for use, lead to the cost to rise, if induction part is rotatory along with the door closure, lead to easily that the detection precision is low excessively, influence the accuracy of control.

Further, the door cover and the motor are preferably located on the same side of the reduction gear set, and the door cover and the motor are convenient to install in a narrow space of the vehicle body.

An acceleration mode: if the user suspects that the movement speed of the door cover is too low, the user may continuously pull or push the door cover to cause the rotary sensor to send a feedback signal, when the absolute value of the change rate of the feedback signal exceeds a preset value and the duration time also exceeds the preset value, the motor accelerates to drive the door cover to rotate, the rotary sensor feeds back the rotation angle in real time, and when the door cover is determined to be opened or closed in place, the motor stops rotating to complete the opening or closing action of the door cover; the operating voltage of the motor in the acceleration mode is greater than the operating voltage of the motor in the full-automatic mode. The allowable operating voltage of the motor is a range, such as a rated 12V motor, and the motor can generally operate in a range of 9-16V. If the voltage during full-automatic mode is 12V, the voltage of acceleration mode can be in 12V ~16V within range to improve the rotational speed of motor, the door closure speed of opening and close also can be faster, thereby satisfies the driver and crew and wants to accelerate the demand of door closure speed of opening and close.
