The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.
Fig. 1 and 2 show a charging port opening device 100 according to the present invention, wherein the charging port opening device 100 includes a charging port cover 40, a charging port case 50, a connecting rod 70, a power device 60, a first rotating shaft 20, and a second rotating shaft 30.
Wherein, the charging port box 50 is inwards sunken relative to the automobile side wall sheet metal 10. The charging port box 50 is provided with a charging port for charging the vehicle. The charging port cover 40 is provided to cover the charging port case 50. When the charging port cover 40 is covered on the charging port box 50, the shape radian of the charging port cover 40 is identical to that of the automobile side wall metal plate 10.
The link 70 is provided on the side of the charging port case 50 away from the charging port cover 40. In the present embodiment, the link 70 includes two first links 21 arranged side by side in the front-rear direction, and two second links 31 arranged side by side in the front-rear direction and arranged side by side in the up-down direction with the first links 21. The first links 21 are connected to each other by a first rotating shaft 20, and the second links 31 are connected to each other by a second rotating shaft 30. The middle part of the first rotating shaft 20 is provided with a first gear 24, the output shaft of the power device 60 is provided with a second gear 61, and the first connecting rod 21 is in transmission connection with the power device 60 through the first gear 24 and the second gear 61. The power device 60 in this embodiment is a stepping motor, and the stepping motor is arranged at the middle position of the first rotating shaft 20, and transmits the torque uniformly towards the two ends through a gear pair, so as to drive the first connecting rod 21 to rotate, and the small-power stepping motor can be used to drive the large charging opening cover 40, and meanwhile, the stress on the two ends of the charging opening cover 40 is uniform, and the charging opening cover 40 advances or retreats at the same speed when being opened.
As shown in fig. 2 and 4, the charging port box 50 is installed on the automobile side wall metal plate 10, the charging port box 50 is buckled on the automobile side wall metal plate 10, the charging port box 50 is located below the charging port cover 40, a circular opening 51 is arranged in the middle of the charging port box 50 and used for accommodating a charging port, curved surfaces are arranged on two sides of the circular opening 51, two rotating movable grooves 52 are formed in the curved surfaces, the rotating movable grooves 52 have two end portions, and the two end portions are respectively an initial end 53 and a termination end 54. The first link 21 and the second link 31 extend from the rotation movable slot 52 out of the charging port case 50 and are pivotally connected to the charging port cover 40. The power unit 60 drives the first link 21 and the second link 31 to move between the start end 53 and the end 54 of the movable rotating slot 52, so as to drive the charging port cover 40 to cover the charging port case 50 or expose the charging port case 50. The power unit 60 is also connected to a control device (e.g., a vehicle body controller) for automatically controlling the movement of the link between the start end 53 and the end 54 of the pivoting movable slot 52 according to a control signal from the control device so that the charging port cover 40 covers or exposes the charging port cover 40.
Referring to fig. 3 and 4, a fan-shaped frame 22 is disposed on a side of the first link 21 away from the second link 31, and an arc surface 23 is disposed on an end of the fan-shaped frame 22 close to the charging port cover 40. The arc surface 23 and the curved surface of the rotating arm movable groove 53 are concentric circles. The arc surface 23 of the segment frame 22 can block the rotation arm movable groove 53 when the link moves between the start end 53 and the termination end 54 of the rotation movable groove 52. The curved surfaces of the sector frame 22 and the movable rotating groove 52 are concentric circles, and when the sector frame 22 rotates, the sector area of the sector frame 22 completely fits the movable rotating groove 52, so that when the charging port cover 40 moves up and down, the arc surface 23 of the sector frame 22 is always arranged in the movable rotating groove 52 to shield the movable rotating groove 52.
Further, in order to increase the shielding effect of the arc surface 23 on the rotating arm moving groove 53, a sealing structure is further arranged between the arc surface 23 and the rotating arm moving groove 53. The sealing structure can be a flange 55 arranged on the inner side of the rotating arm movable groove 53, the flange 55 extends from the inner side of the rotating arm movable groove 53 to the fan-shaped frame 22 along the direction perpendicular to the charging port box 50, the distance between the rotating arm movable groove 53 and the arc surface 23 can be effectively reduced, and the shielding effect is increased. In other embodiments of the present invention, the sealing structure may also be a rubber ring provided inside the swivel arm moving groove 53. The sealing design can protect outside rainwater sundries from entering the inner space when the charging opening cover 40 is opened, and the safety of the inner space is ensured.
The first rotating shaft 20, the second rotating shaft 30, the first link 21, the second link 31 and the charging port cover 40 form a four-link structure, which has strong stability and can stably realize normal mechanical movement under complex vehicle conditions. The operator sends a control instruction to the vehicle body controller, the vehicle body controller sends a pulse signal to the stepping motor, the stepping motor converts the pulse signal into angular displacement, when a gear shaft of the stepping motor rotates outwards, the driving gear 24 rotates inwards, and then the charging opening cover 40 in the four-bar structure moves downwards to be opened; when the gear shaft of the stepping motor rotates inward, the driving gear 24 rotates outward, and the charging port cover 40 in the four-bar linkage structure moves upward to be fastened.
Charging port opening device 100 can the arbitrary position installation for charging port cover 40 can open and shut in arbitrary position, and this kind of characteristic that can the arbitrary position installation can both normal use in a wide variety of overall arrangements, makes charging port opening device 100 have very strong commonality, has higher economic value.
The invention also provides an electric vehicle comprising the charging port opening device 100.
In summary, the charging port opening device 100 of the present invention realizes automatic opening and closing of the charging port cover 40, provides a stable four-bar linkage based drive, and can drive the charging port cover 40 to perform a stable movement by a stepping motor with a smaller power, so that the charging is more convenient.
