As can be understood by those skilled in the art, in the technical solution of the present invention, the axial movement mechanism of the present invention includes a driving member, a first connecting shaft and a first transmission member, wherein the driving member is connected to the first connecting shaft so as to drive the first connecting shaft to rotate, so that a user can control the operation of the axial movement mechanism by controlling the operation condition of the driving member, thereby effectively realizing automatic control; the first transmission member is fitted over the first coupling shaft, an outer surface of the first coupling shaft is provided with one of an arc-shaped guide groove and a guide pin, an inner surface of the first transmission member is provided with the other of the arc-shaped guide groove and the guide pin, and the arc-shaped guide groove and the guide pin are fitted to each other so that the first coupling shaft is axially moved in a first direction with respect to the first transmission member when the first coupling shaft is driven to rotate by the driving member and the first transmission member is fixed. The invention guides the relative movement between the first connecting shaft and the first transmission member by arranging the arc-shaped guide groove and the guide pin between the first connecting shaft and the first transmission member, so that the first connecting shaft can generate axial movement while the driving member drives the first transmission shaft to rotate, namely, the invention converts the rotary movement into the axial movement only by additionally arranging the arc-shaped guide groove and the guide pin between the first connecting shaft and the first transmission member; particularly, when a user only needs to realize short-distance axial movement, the arrangement mode not only can effectively simplify the whole structure of the axial movement mechanism, thereby reducing the manufacturing cost of the axial movement mechanism, but also can effectively improve the reliability of transmission.
Further, it can be understood that, since the outer surface of the first connecting shaft is more easily processed than the inner surface of the first transmission member, as a preferred embodiment, the arc-shaped guide groove is provided on the outer surface of the first connecting shaft, and the guide pin is provided on the inner surface of the first transmission member, so as to effectively simplify the manufacturing process of the axial movement mechanism.
Further, the present invention is also configured such that the first branch grooves and the second branch grooves are arranged in a structure extending in opposite directions with ends meeting each other, so that the first connecting shaft moves axially in the first direction with respect to the first transmission member regardless of the direction in which the first connecting shaft rotates; i.e. the first connecting shaft is capable of producing a co-directional axial movement irrespective of whether the drive member is rotating in the forward or reverse direction.
Furthermore, the present invention further provides a reset member, so that when the driving member stops driving the first connecting shaft, the first connecting shaft can return to the initial position in a second direction opposite to the first direction under the action of the reset member, so that the first connecting shaft can be automatically reset.
Meanwhile, as can be further understood by those skilled in the art, the present invention enables the lock actuator to have a locking function by applying the axial movement mechanism to the lock actuator and connecting the lock member to the first connecting shaft so that the lock member can move between a locking position and an unlocking position in accordance with the axial movement of the first connecting shaft. Specifically, existing actuators typically have only a drive function, and not a lock-up function; however, in many existing application scenarios, the driving function and the locking function are often required to be applied simultaneously, for example, various door assemblies often need to have the driving function and the locking function simultaneously, so as to drive the door body to rotate and lock the door body, and therefore, the existing door assembly needs to be provided with at least two actuators, one of which is used for driving the door body to rotate, and the other of which is used for driving the lock cylinder to move so as to lock the door body. Different from the prior art, the locking actuator is additionally provided with the axial movement mechanism, and the locking piece is connected with the first connecting shaft, so that the locking actuator can simultaneously have a driving function and a locking function; on one hand, when the driving member drives the first connecting shaft to rotate to generate axial movement, the locking actuator can play a locking or unlocking role, so that the locking actuator can have a locking function; on the other hand, when the driving member continues to drive the first connecting shaft to rotate so as to drive the first transmission member to synchronously rotate, the locking actuator can play a driving role so that the locking actuator can have a driving function. That is, the lock-up actuator of the present invention is capable of performing functions that are not possible with the prior two actuators.
Furthermore, the first transmission member is the first gear, and the gear is selected as the first transmission member because the manufacturing process of the gear is mature, so that the production process of the axial movement mechanism is simplified, and the mass production is facilitated. Meanwhile, the second gear is meshed with the first gear to realize transmission, and the locked piece is connected with the second connecting shaft, so that the locked piece can rotate through the second connecting shaft, the torque is effectively increased, and the stability and the reliability of the locking actuator are further ensured.
Further, the guide pin of the present invention has a cylindrical structure, so as to ensure that the guide pin can move smoothly in the arc-shaped guide slot, thereby effectively ensuring the guiding effect of the guide pin and the arc-shaped guide slot.
Further, the driving member of the present invention drives the third gear to rotate through the fourth gear, and the radial dimension of the fourth gear is smaller than that of the third gear, so that the output torque of the lock-up actuator can be further increased while achieving deceleration.
Further, the reset member is sleeved on the first connecting shaft and pre-compressed between the flange and the first gear, so that the reset member can provide enough abutting force for the first gear without depending on other auxiliary members, and the rotation of the first connecting shaft relative to the first gear is not influenced. Furthermore, the return member is preferably a spring, so as to effectively save production cost; and the spring is sleeved on the first connecting shaft so as to effectively ensure that the spring and the first gear have enough contact area, and further effectively ensure that the spring can provide enough abutting force for the first gear.
Further, the first connecting shaft of the present invention is rotatably connected to the connecting member, so as to effectively ensure that the first connecting shaft can normally rotate; the locking member is axially movably connected to the connecting member so that unnecessary axial movement of the locking member is effectively avoided while the locking member is effectively ensured to be movable between a locked position and an unlocked position.
Further, the lock actuator of the present invention further includes a damper, the damper is connected to the second connecting shaft, and since the second connecting shaft is connected to the locked member, the locked member has a certain self weight; therefore, the damper is additionally arranged to prevent the second connecting shaft from rotating under the action of gravity of the locked piece when the driving member stops driving, and the stability of the locking actuator is effectively ensured.
Furthermore, the locking actuator further comprises a shell, and the shell not only can support the shaft components, but also can protect the gear components, so that the service life of the locking actuator is effectively prolonged.
Furthermore, it will be understood by those skilled in the art that when the lock actuator of the above preferred embodiment is used in a vehicle, the lock actuator can move the lock member to the unlocked position and drive the shield member to rotate according to the user's instruction, so as to expose the energy charging member for use by the user; or the shielding component is driven to rotate into the energy charging opening and the blocking piece is enabled to lock the shielding component, so that the shielding component can be locked while the energy charging component is blocked to keep the vehicle body in a closed state, and the shielding component is enabled to be locked.

The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
Referring first to fig. 1 to 3, fig. 1 is a schematic view of the overall structure of the axial movement mechanism of the present invention; FIG. 2 is an exploded view of the axial motion mechanism of the present invention; fig. 3 is a schematic view of the overall structure of the lock actuator and the shield member of the present invention. As shown in fig. 1 to 3, the axial movement mechanism includes a first connecting shaft 11, a first gear 12, a reset member 13 and a driving member 14, wherein the driving member 14 is connected with the first connecting shaft 11 so as to drive the first connecting shaft 11 to rotate; it should be noted that the driving member 14 may be directly connected to the first connecting shaft 11, or may be indirectly connected to the first connecting shaft 11, that is, connected through another member, as long as the driving member 14 can drive the first connecting shaft 11 to rotate; meanwhile, the driving member 14 is preferably a motor, and of course, a skilled person may select other members with driving functions according to actual use requirements. Meanwhile, the first gear 12 is sleeved on the first connecting shaft 11, two arc-shaped guide grooves 111 are formed in the outer surface of the first connecting shaft 11, and the two arc-shaped guide grooves 111 are symmetrically arranged; the inner surface of the first gear 12 is correspondingly provided with two guide pins 121, the two guide pins 121 are also symmetrically arranged, and the arc-shaped guide groove 111 and the guide pins 121 arranged correspondingly to each other can be matched with each other, so that when the driving member 14 drives the first connecting shaft 11 to rotate and the first gear 12 is fixed, the first connecting shaft 11 will move axially relative to the first gear 12 along the side away from the resetting member 13. It should be noted that the present invention does not limit the fixing manner of the first connecting shaft 11, as long as the first connecting shaft 11 can rotate freely and can generate axial movement when being installed in place. In addition, it should be noted that, although the first transmission member is the first gear 12 in the preferred embodiment; however, the first transmission member may be provided in other structures, such as a pulley, and the specific structure of the first transmission member may be set by a technician according to actual use conditions.
It will be understood by those skilled in the art that the driving member 14 may also be directly connected to the first connecting shaft 11 to drive the first connecting shaft 11 to rotate, as long as the driving member 14 does not affect the axial movement of the first connecting shaft 11; for example, a blind hole is formed at one end of the first connecting shaft 11, a sliding groove is formed along the depth direction of the blind hole, a columnar block matched with the shape of the blind hole is connected to the output shaft 141 of the driving member 14, and a sliding block matched with the sliding groove is arranged on the columnar block, so that the driving member 14 can drive the first connecting shaft 11 to rotate circumferentially without limiting the axial movement of the first connecting shaft 11. Meanwhile, although the outer surface of the first connecting shaft 11 is provided with two arc-shaped guide grooves 111 and the inner surface of the first gear 12 is provided with two guide pins 121 in the preferred embodiment, it is obvious that the outer surface of the first connecting shaft 11 may be provided with only one arc-shaped guide groove 111 and the inner surface of the first gear 12 is correspondingly provided with one guide pin 121, and such specific number changes do not depart from the basic principle of the present invention and belong to the protection scope of the present invention.
Further, as shown in fig. 2, in the present preferred embodiment, the arc-shaped guide groove 111 includes a first branch groove 1111 and a second branch groove 1112 whose ends meet each other, and the first branch groove 1111 and the second branch groove 1112 extend in opposite directions such that the first branch groove 1111 and the second branch groove 1112 together form a "herringbone" shaped groove. The left end opening of the arc-shaped guide groove 111 may be closed or opened. The present invention provides that the first connecting shaft 11 is axially moved in the same direction relative to the first gear 12, regardless of the direction in which the first connecting shaft 11 is rotated. It will be understood by those skilled in the art that although the arc-shaped guide groove 111 is described in the present preferred embodiment to include the first branch groove 1111 and the second branch groove 1112 whose ends meet each other; however, it is obvious that the arc guide groove 111 may include only one of the first branch groove 1111 and the second branch groove 1112. Further, it can be understood by those skilled in the art that the guide pin 121 is preferably a cylindrical structure, and of course, this description is not limiting, and those skilled in the art can set the specific shape of the guide pin 121 according to the actual use requirement.
Still further, referring to the orientation shown in fig. 1 and 2, the right end of the first connecting shaft 11 is further provided with a flange 112, the reset member 13 is sleeved on the first connecting shaft 11 and pre-compressed between the flange 112 and the first gear 12, so that the reset member 13 can always generate a resisting force acting on the first gear 12 leftwards and a resisting force acting on the flange 112 rightwards; when the driving member 14 stops driving the first connecting shaft 11, the first connecting shaft 11 moves rightward in the axial direction by the urging force of the returning member 13 to return to the initial position, i.e., the position where the guide pin 121 is located at the leftmost end of the arc-shaped guide groove 111. It will be understood by those skilled in the art that the return member 13 is preferably a spring, but the specific type of return member 13, such as a bungee cord, an elastic block, a pneumatic cylinder, etc., can be selected by those skilled in the art according to the actual application. Meanwhile, although only one return member 13 is provided in the present preferred embodiment, the return member 13 is pre-compressed between the flange 112 and the first gear 12; however, it is obvious to the skilled person that the number and the arrangement positions of the reset members 13 can be set by himself or herself according to the actual use requirement, as long as the first connecting shaft 11 can be returned to the initial position by the reset members 13 when the driving member 14 stops driving the first connecting shaft 11. Furthermore, although the reset member 13 is described in the preferred embodiment as being fitted over the first connecting shaft 11; however, it is obvious that the reset member 13 can also be directly connected between the flange 112 and the first gear 12, i.e. the technician can set the connection relationship between the reset member 13 and the first connecting shaft 11 and between the reset member 13 and the first gear 12 according to the actual use requirement.
Referring next to fig. 3-7, wherein fig. 4 is an exploded view of the lock actuator and shield member of the present invention; FIG. 5 is a first partial schematic view of the lock-up actuator of the present invention; FIG. 6 is a second partial schematic view of the lock actuator of the present invention; FIG. 7 is a first partial exploded view of the lock actuator of the present invention. In the preferred embodiment, as shown in fig. 3 to 7, the first connecting shaft 11 is further provided with a third gear 18, and referring to the orientation in fig. 6 and 7, the third gear 18 is arranged on the right side of the first gear 12, the middle part of the first connecting shaft 11 is provided with a first key groove 113, the inner surface of the third gear 18 is correspondingly provided with a second key groove 181, and the first connecting shaft 11 and the third gear 18 are connected through a flat key 23, so that the first connecting shaft 11 and the third gear 18 can rotate synchronously. It should be noted that, the present invention does not limit any specific connection manner of the first connecting shaft 11 and the third gear 18, as long as the first connecting shaft 11 and the third gear 18 can realize synchronous rotation; in addition, the present invention does not limit the installation position of the third gear 18 on the first connecting shaft 11, and a technician can set the installation position of the third gear 18 on the first connecting shaft 11 according to actual use requirements. Meanwhile, the first connecting shaft 11 is further provided with a nut connection site 115, the nut connection site 115 is provided with threads, and the fixing nut 24 can be screwed onto the nut connection site 115 to function as a shoulder, thereby completely fixing the third gear 18. It will be appreciated by those skilled in the art that although the third gear 18 is fixed by the fixing nut 24 in the preferred embodiment; however, it is obvious to a skilled person that the third gear 18 may also be fixed by other components, such as a shaft shoulder or a limiting protrusion, and the skilled person may set the fixing according to the actual use requirement.

Referring next to fig. 3 and 4, as shown in fig. 3 and 4, in general, a vehicle includes a power supply device, a vehicle body (not shown in the drawings), and a power supply opening provided in the vehicle body, wherein the power supply device includes a shielding member 1001 for closing the power supply opening, and a power supply member provided in the vehicle body, the shielding member 1001 is connected to the lock actuator, and the lock actuator is connected to the vehicle body. It should be noted that, the invention does not limit the specific structure and shape of the energy filling opening and the shielding member 1001, and the technician can set the energy filling opening and the shielding member according to the actual use requirement; the vehicle can be an electric vehicle, a fuel vehicle or a hybrid vehicle; when the vehicle is an electric vehicle, the energy charging component is a charging interface of the electric vehicle, and when the vehicle is a fuel vehicle or a hybrid vehicle, the energy charging component is a fuel interface of the vehicle. Specifically, in the preferred embodiment, the shielding member 1001 is provided with a locking hole 1002 and a connecting hole 1003, and one end of the second connecting shaft 16 can be connected to the connecting hole 1003 provided on the shielding member 1001, so that the second connecting shaft 16 can drive the shielding member 1001 to synchronously rotate; and a limit assembly (not shown) capable of limiting a rotation range of the shielding member 1001 is provided on the vehicle body. As a preferred embodiment, the locking member 15 is a bolt, and the bolt is an arc-shaped cylindrical structure, and the cross sections of the cylindrical structure and the lock hole 1002 are both circular; when the lock piece 15 is inserted into the lock hole 1002, the lock actuator can lock the shielding member 1001 to restrict the shielding member 1001 from rotating; when the locking member 15 is moved out of the locking hole 1002, the second connecting shaft 16 can drive the shielding member 1001 to rotate synchronously to move the shielding member 1001 out of the energy charging opening. Furthermore, it will be understood by those skilled in the art that although the latch member 15 is described in the preferred embodiment as an arc-shaped cylindrical bolt; however, this description is not restrictive, and the skilled person can obviously set the specific structure and shape of the locking member 15 according to the actual use requirement, for example, the locking member 15 can obviously also be a lock clip or the like.
Based on the locking actuator described in the above preferred embodiment, and referring to the orientation shown in fig. 3 and 4, when the user needs to use the energy charging member, the user can control the driving member 14 to rotate clockwise, so that the driving member 14 drives the fourth gear 19 to rotate clockwise to drive the third gear 18 and the first connecting shaft 11 to rotate counterclockwise, at this time, the first gear 12 is in a non-rotating state under the urging force of the reset member 13, the first connecting shaft 11 rotates and moves axially to the left under the guiding action of the guide pin 121 and the first branch groove 1111 against the urging force of the reset member 13, so that the locking member 15 moves outwards, that is, the locking member 15 moves from the locking position to the unlocking position, so that the second connecting shaft 16 can drive the shielding member 1001 to rotate synchronously; then, under the abutting action of the guide pin 121 and the first branch groove 1111, the first gear 12 can only overcome the abutting force of the reset member 13 to rotate, that is, the first connecting shaft 11 can drive the first gear 12 to rotate synchronously; meanwhile, when the first gear 12 rotates synchronously in the counterclockwise direction along with the first connecting shaft 11, the first gear 12 can drive the second gear 17 to rotate clockwise, so that the second gear 17 and the second connecting shaft 16 can rotate synchronously in the clockwise direction, and the shielding member 1001 rotates upwards, until the energy filling member is exposed, and the driving member 14 stops driving; in addition, it should be noted that, when the driving member 14 stops driving, the first gear 12 is in a non-rotating state again under the action of the urging force of the returning member 13; at the same time, the reset member 13 applies a rightward abutting force to the first coupling shaft 11, so that the first coupling shaft 11 is rotated clockwise while being moved axially by the guide pin 121 and the first branch groove 1111, thereby moving the locking piece 15 from the unlocking position to the locking position again. It will be appreciated that since the shielding member 1001 is not located in the energy charging opening, the locking member 15 will not be inserted into the locking hole 1002 when in the locking position, i.e. although the locking member 15 is in the locking position, the shielding member 1001 will not be locked, but only the locking member 15 will return to the locking position. Similarly, when the user does not need to use the energy charging member, the user only needs to control the driving member 14 to rotate counterclockwise until the shielding member 1001 rotates into the energy charging opening, and the whole movement process is exactly opposite to the above movement process, and will not be described herein again.
