Description

Door cover assembly, door cover opening and closing control method and door lock
Technical Field
The invention relates to the field of door locks, in particular to a door cover assembly for a vehicle, a door cover opening and closing control method and a door lock.
Background
Currently, an energy supply port of an automobile, for example, an automobile in which a fuel filler port for supplying fuel or oil and/or a charging port for supplying electric power are provided, is usually shielded by a door cover, and opening and closing of the door cover is controlled by a door lock. For example, when refueling or charging is needed, the door lock is driven to open the door cover, so that the door cover is far away from the refueling port or the charging port, the refueling port or the charging port is exposed, further fuel or electric power is supplemented to the automobile, and after the supplementation is completed, the door lock is driven to close the door cover, so that the refueling port or the charging port is shielded by the door cover again.
However, the above procedure is inconvenient because the door lock is operated manually to open or close the door cover. However, in an automatic control manner, for example, the refueling or charging port door lock and the refueling or charging port cover assembly thereof disclosed in patent CN201710687660.5 drive the lifting shaft to move so as to drive the door cover to move, thereby opening and closing the door cover, but the movement of the lifting shaft is mainly completed by the sliding fit between the positioning pin and the sliding groove, the positioning pin is easily disengaged from the sliding groove, and further the movement of the lifting shaft becomes uncontrollable, and the door cover cannot be controlled to be opened or closed, so that the working reliability is poor, and the service life is short.
In addition, the axial movement distance of the lifting shaft only performing ascending movement and descending movement is determined by the height of the straight groove part in the sliding groove. However, since the types of vehicles are varied, for example, in some types of vehicles, the door cover needs to be raised to a high height relative to the filler opening or the charging opening, and its subsequent rotational movement is not blocked. For other types of vehicles, the door cover only needs to be raised to a small height relative to the filler opening or charging opening, and its subsequent rotational movement is not blocked. If the worm gear is suitable for different types of automobiles, the track worms with different straight groove heights need to be machined and manufactured again, and the corresponding track worms need to be replaced correspondingly, which is troublesome.

The specific meanings of the above terms in the present invention can be understood according to specific situations by those of ordinary skill in the art.
The door cover assembly is mainly used for being installed on a vehicle so as to shield or open an energy supply port of the vehicle. For example, the door assembly is mounted to a fuel filler box or a charging box of an automobile so as to shield a fuel filler opening of the fuel filler box or a charging opening of the charging box, or to open the fuel filler opening of the fuel filler box or the charging opening of the charging box so that the fuel filler opening of the fuel filler box or the charging opening of the charging box is exposed.
Referring to fig. 1 and 2, the door lock 100 of the present invention is mainly used for driving the door cover 200 to move, so as to switch the door cover 200 between the closed position (i.e. the position of the door cover 200 in fig. 1) and the open position (i.e. the position of the door cover 200 in fig. 2), thereby achieving the purpose of controlling the opening and closing of the door cover 200.
The door lock 100 of the present invention includes a housing 10, a lifting assembly 20, and a driving rotating assembly 30.
Specifically, the housing 10 may include a first housing 11 and a second housing 12, and is formed by detachably splicing the first housing 11 and the second housing 12. Of course, the housing 10 may also be made by other processing methods, such as welding, and the like, which will not be described herein.
Fig. 3 is a schematic structural view of the present invention with the first housing 11 removed, and in conjunction with fig. 3, the lifting assembly 20 includes a lifting member 21 and a driving shaft 22. The lifting member 21 is disposed in the housing 10 and has a lifting base 211 capable of lifting, the bottom end of the driving shaft 22 is rotatably disposed on the lifting base 211, and the top end of the driving shaft 22 penetrates through the housing 10 and is used for connecting the door 200.
The driving rotation assembly 30 includes a driving rack 31, a driving rotation gear set 32 and an elastic restoring member 33. The driving rack 31 is disposed in the housing 10 in a liftable manner, and the driving rack 31 is located above the lifting seat 211 and spaced from the lifting seat 211 by a predetermined distance. The driving rotary gear set 32 is disposed in the housing 10, and the driving rotary gear set 32 is engaged with the driving rack 31 and can drive the driving shaft 22 to be rotatably sleeved on the outer side of the driving shaft 22. Both ends of the elastic restoring member 33 contact the housing 10 and the driving rack 31, respectively.
When the lifting base 211 is lifted, the driving shaft 22 is lifted along the axial direction thereof as the lifting base 211 is lifted, and after the lifting base 211 is contacted with the driving rack 31, the lifting base 211 is lifted to drive the driving rack 31 to be lifted, the driving rotary gear set 32 is rotated as the driving rack 31 is lifted, and the driving rotary gear set 32 is rotated to drive the driving shaft 22 to rotate around the axial direction thereof, so that the driving shaft 22 is lifted along the axial direction thereof and rotated around the axial direction thereof, and the door 200 is driven to leave the closed position, and the door 200 is opened.
In other words, before the door cover 200 is not opened, the initial position of the door cover 200 defaults to a closed position, i.e., a position in which the door cover 200 is located in fig. 1, and in which the door cover 200 may shield a fuel filler or a charging port of the vehicle.
At this time, the housing 10 is fixed, the lifting seat 211 is driven to ascend, the lifting seat 211 ascends to drive the driving shaft 22 to ascend axially, then when the lifting seat 211 ascends to contact with the driving rack 31, the lifting seat 211 continuously ascends to drive the driving rack 31 to ascend, the driving rack 31 ascends to drive the driving rotating gear set 32 to drive the driving shaft 22 to rotate axially, for example, to drive the driving shaft 22 to rotate counterclockwise axially. That is, in the process, the housing 10 is fixed, the driving shaft 22 first rises axially and then rotates and rises relative to the housing 10, and then drives the door 200 to rise axially and then rotate and rise, so that the door 200 is separated from the original closed position, and the door 200 moves to the open position shown in fig. 2, thereby opening the door 200.
When the lifting seat 211 descends, the driving shaft 22 descends along the axial direction thereof as the lifting seat 211 descends, the driving rack 31 descends and returns under the elastic force of the elastic returning member 33, the driving rotary gear set 32 rotates in the opposite direction to the previous direction as the driving rack 31 descends, so that the driving shaft 22 descends along the axial direction thereof and rotates in the opposite direction to the previous direction simultaneously under the combined action of the driving rotary gear set 32 and the lifting seat 211, and after the lifting seat 211 is disengaged from the driving rack 31, the driving shaft 22 descends along the axial direction as the lifting seat 211 descends to return to the initial closed position, so that the door cover 200 is closed.
That is, when the door 200 returns to the closed position shown in fig. 1 from the open position shown in fig. 2 again, the lifting seat 211 is first driven to descend, the driving shaft 22 is driven to descend along the axial direction by the descending of the lifting seat 211, the driving rack 31 is driven to descend and reset by the elastic reset piece 33, and the driving rotating gear set 32 is driven to rotate in the direction opposite to the opening direction by the descending of the driving rack 31, so that the driving shaft 22 rotates in the opposite direction and descends under the combined action of the driving rotating gear set 32 and the lifting seat 211. For example, the drive shaft 22 rotates clockwise about its axial direction and descends. When the driving rack 31 is no longer driven to descend by the elastic restoring member 33, and the driving rack 31 is separated from the lifting seat 211, the lifting seat 211 is continuously controlled to descend, so that the driving shaft 22 continues to descend along the axial direction, and the driving shaft 22 rotates in the opposite direction first and then descends along the axial direction, so as to drive the door cover 200 to rotate in the opposite direction first and descend along the axial direction, and then the door cover 200 returns to the previous closing position, thereby closing the door cover 200.
Therefore, the door lock 100 of the present invention can control the door cover 200 to open and close, and has high operational reliability and long service life.
In addition, it is worth mentioning that the axial movement distance of the driving shaft 22 during only the ascending movement and the descending movement is convenient to adjust, that is, the axial movement distance of the driving shaft 22 during only the axial ascending movement and only the axial descending movement is adjusted by adjusting the initial predetermined distance between the driving rack 31 and the lifting seat 211, and further the axial movement distance of the door cover 200 during only the axial ascending movement and only the axial descending movement is adjusted, so that the door cover 200 can be applied to different types of vehicles, and the application range of the door cover 200 is improved.
For example, when the door 200 is lifted to a high height with respect to the power supply port of the vehicle to be rotated, the driving rack 31 and the lifting seat 211 may be assembled in the housing 10, and the driving rack 31 may be moved upward with respect to the lifting seat 211, so that the initial predetermined distance between the driving rack 31 and the lifting seat 211 is increased. As a result, the axial movement distance of the door 200 only in the upward movement is increased, so that the door 200 is rotated when it is raised to a high height with respect to the energy supply port of the vehicle.
When the door 200 is rotated by being raised to a small height with respect to the power supply port of the vehicle, the driving rack 31 and the lifting seat 211 are assembled in the housing 10, and the driving rack 31 is moved downward with respect to the lifting seat 211, so that the initial predetermined distance between the driving rack 31 and the lifting seat 211 is reduced. Accordingly, the axial movement distance of the door 200 only in the upward movement is reduced, and the door 200 is rotated when it is raised to a small height with respect to the energy supply port of the vehicle.
Meanwhile, according to the above analysis, the opening and closing control method of the door 200 of the present invention may include the steps of:
s10: the elevating base 211 is driven to ascend so that the driving shaft 22 ascends in the axial direction thereof as the elevating base 211 ascends.
S20: after the lifting seat 211 is lifted to a position contacting with the driving rack 31, the driving rack 31 is driven to lift by the lifting seat 211, so that the driving rack 31 is lifted to drive the driving rotary gear set 32 to rotate, and the driving rotary gear set 32 is rotated to drive the driving shaft 22 to rotate, so that the driving shaft 22 is lifted along the axial direction and rotated around the axial direction, so as to drive the door cover 200 to be opened.
S30: the lifting seat 211 is driven to descend, the elastic resetting piece 33 drives the driving rack 31 to descend and reset, the driving rack 31 descends to drive the driving rotating gear set 32 to rotate in the direction opposite to the previous direction, and the driving rotating gear set 32 rotates in the direction opposite to the previous direction to drive the driving shaft 22 to rotate, so that the driving shaft 22 descends in the axial direction and rotates in the direction opposite to the previous direction.
