[0044] The executor 100 according to the embodiment of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0045] As shown in FIGS. 1 to 5, the executor 100 according to the embodiment of the present disclosure includes a housing 10, a rotating shaft 20, and a guide shaft 30.

[0046] Specifically, the housing 10 is provided with a receiving cavity 11. The rotating shaft 20 is movably arranged on the housing 10 along a first direction, and a part of the rotating shaft 20 is located in the receiving cavity 11, and the rotating shaft 20 is rotatable relative to the housing 10. The guide shaft 30 is arranged in the receiving cavity 11 along a second direction, and the side of the rotating shaft 20 facing the guide shaft 30 is provided with a guide portion 21, and the guide portion 21 is in contact with the guide shaft 30. In the case of pressing the rotating shaft 20, the guide shaft 30 cooperates with the guide portion 21 to rotate the rotating shaft 20, so that the guide shaft 30 is movable relative to the guide portion 21 between a first position and a second position. In the case that the guide shaft 30 is located at the first position relative to the guide portion 21, the actuator 100 is in a closed state; in the case that the guide shaft 30 is located at the second position relative to the guide portion 21, the actuator 100 is in an open state.

[0047] In other words, as shown in FIGS. 1 and 2, the actuator 100 according to the embodiment of the present disclosure is mainly used to control the opening or closing of the flap in the vehicle, and the flap in the vehicle can be the charging flap, the refueling flap or the flap structure of the storage box on the vehicle. The actuator 100 of the present disclosure mainly consists of a housing 10, a rotating shaft 20 and a guide shaft 30. As shown in FIGS. 3 and 4, the housing 10 is provided with a receiving cavity 11. The rotating shaft 20 can move along a first direction, and the rotating shaft 20 is mounted on the housing 10, and a part of the rotating shaft 20 extends into the receiving cavity 11, and the rotating shaft 20 is rotatable relative to the housing 10. When a user presses the rotating shaft 20, the rotating shaft 20 can rotate in the housing 10. The guide shaft 30 is mounted in the receiving cavity 11 along a second direction, and the first direction and the second direction can be understood as two directions perpendicular to each other, wherein the rotating shaft 20 is inserted into the housing 10 along the vertical direction, and the guide shaft 30 is mounted in the housing 10 along the horizontal direction, and the end of the rotating shaft 20 abuts against the end of the guide shaft 30.

[0048] As shown in FIG. 5, the side of the rotating shaft 20 facing the guide shaft 30 is provided with a guide portion 21, and the guide portion 21 of the rotating shaft 20 is always in contact with the guide shaft 30 during the pressing process of the rotating shaft 20 by the user. In the case of pressing the rotating shaft 20, the guide shaft 30 cooperates with the guide portion 21 to rotate the rotating shaft 20, so that the guide shaft 30 is movable relative to the guide portion 21 between a first position and a second position. When the rotating shaft 20 is pressed, the switching of the guide shaft 30 between the first position and the second position improves the certainty of the rotating shaft 20 in the rotating direction, ensures that the rotating shaft 20 can rotate in the set direction, and by arranging the guide portion 21 on the rotating shaft 20, the volume of the actuator 100 is greatly reduced, which is conducive to the miniaturization design of the overall structure of the actuator 100, and ensures that the actuator 100 can realize the functions of pressing opening or closing in a very small installation space.

[0049] Thus, the actuator 100 according to the embodiments of the present disclosure greatly simplifies the complexity of the actuator 100 by arranging the guide portion 21 on the rotating shaft 20, the guide portion 21 being in contact with the guide shaft 30, and by switching the guide shaft 30 relative to the guide portion 21 between the first position and the second position when the rotating shaft 20 is pressed, effectively reducing the parts of the actuator 100, and facilitating the miniaturization design of the overall structure of the actuator 100, and ensuring that the actuator 100 realizes the pressing opening or closing function in a very small installation space.

[0050] According to one embodiment of the present disclosure, the guide portion 21 includes a plurality of stepped surfaces 210, and the plurality of stepped surfaces 210 form a height difference in the radial direction of the rotating shaft 20. In the case of pressing the rotating shaft 20, the rotating shaft 20 rotates, and the guide shaft 30 can be in contact with the plurality of stepped surfaces 210 respectively, so as to switch the guide shaft 30 relative to the guide portion 21 between the first position and the second position.

[0051] In other words, as shown in FIG. 7, the guide portion 21 mainly consists of a plurality of stepped surfaces 210, wherein the plurality of stepped surfaces 210 form a stepped structure with a height difference in the radial direction of the rotating shaft 20. In the case of pressing the rotating shaft 20, the rotating shaft 20 rotates, and the plurality of stepped surfaces 210 can be in contact with the guide shaft 30 respectively, so as to switch the guide shaft 30 relative to the guide portion 21 between the first position and the second position during the rotation of the rotating shaft 20, and ensure that the actuator 100 realizes the pressing opening function in a very short pressing stroke.

[0052] According to one embodiment of the present disclosure, the plurality of stepped surfaces 210 include a first stepped surface 211, a second stepped surface 212, a third stepped surface 213, and a fourth stepped surface 214, and the first stepped surface 211, the second stepped surface 212, the third stepped surface 213, and the fourth stepped surface 214 are sequentially distributed along the circumference of the guide shaft 30. In the case that the guide shaft 30 is in contact with the third stepped surface 213, the guide shaft 30 is in the first position relative to the guide portion 21, and the actuator 100 is in the closed state; in the case that the guide shaft 30 is in contact with the first stepped surface 211, the guide shaft 30 is in the second position relative to the guide portion 21, and the actuator 100 is in the open state.

[0053] That is, referring to FIG. 7, the plurality of stepped surfaces 210 mainly consist of a first stepped surface 211, a second stepped surface 212, a third stepped surface 213, and a fourth stepped surface 214, wherein the first stepped surface 211, the second stepped surface 212, the third stepped surface 213, and the fourth stepped surface 214 are sequentially distributed relative to the circumference of the guide shaft 30. In the case that the guide shaft 30 is in contact with the third stepped surface 213, the guide shaft 30 is in the first position relative to the guide portion 21, and at this time, the actuator 100 is in the closed state.

[0054] Specifically, when the guide shaft 30 is in contact with the third step surface 213, the guide shaft 30 is in the first position relative to the guide portion 21, and the actuator 100 is in the closed state. At this time, the locking member 40 can be inserted into or separated from the locking hole 22. When the locking member 40 is inserted into the locking hole 22, the actuator 100 is in the locked state, and the guide shaft 30 is not movable between the first position and the second position relative to the guide portion 21, so that the actuator 100 cannot be opened by pressing the rotating shaft 20. When the locking member 40 is separated from the locking hole 22, the actuator 100 is in the unlocked state, and the guide shaft 30 is movable between the first position and the second position relative to the guide portion 21, so that the actuator 100 can be opened or closed by pressing the rotating shaft 20. When the guide shaft 30 is in contact with the bottom of the first step surface 211, the guide shaft 30 is in the second position relative to the guide portion 21, and the actuator 100 is in the open state.

[0055] In the present disclosure, when the guide shaft 30 is located at the first step surface 211, the guide shaft 30 is in the second position, and at this time, the actuator 100 is in the open state. By switching the guide shaft 30 between the third step surface 213 and the first step surface 211, the certainty of the rotating shaft 20 in the rotating direction is improved, so that the rotating shaft 20 can rotate in the set direction, the pressing stroke of the actuator 100 is greatly reduced, the miniaturization design of the overall structure of the actuator 100 is facilitated, and the actuator 100 can realize the pressing opening function in a very short pressing stroke.

[0056] According to one embodiment of the present disclosure, when the actuator 100 is switched from the closed state to the open state, the guide shaft 30 is sequentially rotated from the third step surface 213 to the fourth step surface 214 and then to the first step surface 211 relative to the guide portion 21. When the actuator 100 is switched from the open state to the closed state, the guide shaft 30 is sequentially rotated from the first step surface 211 to the second step surface 212 and then to the third step surface 213 relative to the guide portion 21.

[0057] That is, as shown in FIG. 7, when the rotating shaft 20 is pressed, when the actuator 100 is switched from the closed state to the open state, the guide shaft 30 can be sequentially rotated from the third step surface 213 to the fourth step surface 214 and then to the first step surface 211 relative to the guide portion 21. At this time, the guide shaft 30 is in the second position, and the actuator 100 is in the open state. When the actuator 100 is switched from the open state to the closed state, the guide shaft 30 can be sequentially rotated from the first step surface 211 to the second step surface 212 and then to the third step surface 213 relative to the guide portion 21. At this time, the guide shaft 30 is in the first position, the actuator 100 is in the closed state, and the locking member 40 can be inserted into or separated from the locking hole 22. When the locking member 40 is inserted into the locking hole 22, the actuator 100 is in the locked state. When the locking member 40 is separated from the locking hole 22, the actuator 100 is in the unlocked state.

[0058] According to one embodiment of the present disclosure, the first step surface 211, the second step surface 212, the third step surface 213, and the fourth step surface 214 form a height difference with the outer wall surface 219 of the rotating shaft 20, and the height of the outer wall surface 219 of the rotating shaft 20 in the radial direction thereof is higher than the first step surface 211, the second step surface 212, the third step surface 213, and the fourth step surface 214. The second step surface 212 and the third step surface 213 form a height difference with the first step surface 211, and the height of the first step surface 211 in the radial direction of the rotating shaft 20 is higher than the second step surface 212 and the third step surface 213 near the second step surface 212 and the third step surface 213. The second step surface 212 forms a height difference with the third step surface 213 and the fourth step surface 214, and the height of the second step surface 212 in the radial direction of the rotating shaft 20 is higher than the third step surface 213. The height of the second step surface 212 in the radial direction of the rotating shaft 20 is higher than the fourth step surface 214. Of course, the rotating shaft 20 can further include a first side wall surface 215, which is a connecting surface between the fourth step surface 214 and the outer wall surface 219 of the rotating shaft 20.

[0059] In other words, as shown in FIG. 7, the first step surface 211 and the second step surface 212 form a height difference with the outer wall surface 219 of the rotating shaft 20, and the face formed by the height difference is referred to as a second side wall surface 216. The height of the outer wall surface 219 of the rotating shaft 20 in the radial direction thereof is higher than the first step surface 211 and the second step surface 212. The second step surface 212 and the third step surface 213 form a height difference with the first step surface 211, and the face formed by the height difference is referred to as a second face 217. The height of the first step surface 211 in the radial direction of the rotating shaft 20 is higher than the second step surface 212 and the third step surface 213 near the second step surface 212 and the third step surface 213. The second step surface 212 forms a height difference with the third step surface 213 and the fourth step surface 214, and the face formed by the height difference is referred to as a third face 218. The height of the second step surface 212 in the radial direction of the rotating shaft 20 is higher than the third step surface 213. The height of the second step surface 212 and the third step surface 213 in the radial direction of the rotating shaft 20 is higher than the fourth step surface 214 near the fourth step surface 214. That is, the height of the second step surface 212 in the radial direction of the rotating shaft 20 is higher than a portion of the fourth step surface 214. The outer wall surface 219 of the rotating shaft 20 forms a height difference with the first step surface 211 and the fourth step surface 214, and the height of the outer wall surface 219 of the rotating shaft 20 in the radial direction thereof is higher than the first step surface 211 and the fourth step surface 214.

[0060] The outer wall surface 219 of the rotating shaft 20 forms the second side wall surface 216 and the first side wall surface 215 with the first step surface 211 and the fourth step surface 214, and the height of the outer wall surface 219 of the rotating shaft 20 in the radial direction is higher than that of the first step surface 211 and the fourth step surface 214. During the pressing of the rotating shaft 20, the guide shaft 30 reciprocates between the third step surface 213, the fourth step surface 214, the first step surface 211, the second step surface 212, and the third step surface 213 through the rotation of the rotating shaft 20, so as to realize the continuous switching of the actuator 100 between the open state and the closed state, improve the certainty of the rotating shaft 20 in the rotating direction, ensure that the rotating shaft 20 can rotate in the set direction, greatly reduce the pressing stroke of the actuator 100, facilitate the miniaturization design of the overall structure of the actuator 100, and ensure that the actuator 100 can realize the pressing opening or closing function in a very small installation space.

[0061] According to one embodiment of the present disclosure, as shown in FIG. 7, the first step surface 211 and the fourth step surface 214 form inclined surfaces with an inclined angle. By setting the first step surface 211 and the fourth step surface 214 as inclined surfaces with an inclined angle, the height difference between the first step surface 211, the second step surface 212, the third step surface 213, and the fourth step surface 214 can be effectively adjusted, and it is ensured that the upper end of the first step surface 211 is higher than the second step surface 212, the second step surface 212 is higher than the third step surface 213, the third step surface 213 is higher than the upper end of the fourth step surface 214, and the lower end of the fourth step surface 214 is higher than the lower end of the first step surface 211. The actuator 100 can be designed according to the structure of the guide part 21, and the relative positions of the guide shaft 30 and the rotating shaft 20 can be returned to the original positions through twice pressing or contact pressing.

[0062] According to one embodiment of the present disclosure, as shown in FIG. 7, in the radial direction of the rotating shaft 20, the first step surface 211 is higher than the second step surface 212 and the third step surface 213 at the position connected with the second step surface 212 and the third step surface 213. The first step surface 211 is lower than the fourth step surface 214 at the position connected with the fourth step surface 214. The fourth step surface 214 forms an inclined surface with an inclined angle, and the fourth step surface 214 is lower than the second step surface 212 and the third step surface 213 at the position connected with the second step surface 212 and the third step surface 213, and the fourth step surface 214 is higher than the first step surface 211 at the position connected with the first step surface 211. The actuator 100 can be designed according to the structure of the guide part 21, and the relative positions of the guide shaft 30 and the rotating shaft 20 can be returned to the original positions through twice pressing or contact pressing.

[0063] According to one embodiment of the present disclosure, the rotating shaft 20 is provided with a first elastic member 51, the first elastic member 51 extends in the axial direction of the rotating shaft 20, and the first elastic member 51 abuts against the end surface of the inner cavity of the rotating shaft 20.

[0064] That is, as shown in FIG. 5, the rotating shaft 20 is provided with a first elastic member 51, which can be a spring or a compression spring. The first elastic member 51 extends along the axial direction of the rotating shaft 20, and abuts against the end face of the inner cavity of the rotating shaft 20. The rotating shaft 20 can be moved along the longitudinal axis of the rotating shaft 20 by the force of the first elastic member 51 in the housing 10 of the actuator 100, thereby providing a restoring force for the rotation reset of the rotating shaft 20. When the guide portion 21 of the rotating shaft 20 contacts the end face of the guide shaft 30, the external pressure or the elastic force of the first elastic member 51 can be decomposed into a radial component force by the reaction force provided by the guide shaft 30, thereby driving the rotating shaft 20 to rotate. Meanwhile, the provision of the guide portion 21 can improve the certainty of the rotating shaft 20 in the rotation direction, and ensure that the rotating shaft 20 can rotate in the set direction.

[0065] According to one embodiment of the present disclosure, the outer circumferential surface of the guide shaft 30 is provided with a shaft sleeve 60, and the end of the guide shaft 30 away from the rotating shaft 20 is provided with a second elastic member 52.

[0066] In other words, as shown in FIG. 6, the outer circumferential surface of the guide shaft 30 is provided with the shaft sleeve 60, and the end of the guide shaft 30 away from the rotating shaft 20 is provided with the second elastic member 52. The second elastic member 52 is a spring or a compression spring, the guide shaft 30 is installed in the shaft sleeve 60, one end of the guide shaft 30 contacts the second elastic member 52, and the other end contacts the guide portion 21 of the rotating shaft 20. The second elastic member 52 can ensure that the guide shaft 30 is always in contact with the surface of the rotating shaft 20.

[0067] In the present disclosure, as shown in FIGS. 1 and 2, the shaft sleeve 60 is fixedly installed in the housing 10 and fixed by the upper cover 73, for limiting the movement track of the guide shaft 30. By increasing the second elastic member 52 for adjusting the extension length of the guide shaft 30, the pressing force and the stress of the internal components of the actuator 100 are reduced. Meanwhile, the structure design of the prior art, in which a torsion spring is arranged outside the rotating shaft to drive the rotating shaft to rotate, is cancelled, the overall structure is simpler and more compact, and this is conducive to the miniaturization design of the actuator 100.

[0068] According to one embodiment of the present disclosure, as shown in FIG. 6, the radial dimension of the end of the guide shaft 30 close to the rotating shaft 20 is smaller than the radial dimension of the end of the guide shaft 30 away from the rotating shaft 20, so as to facilitate the installation of the second elastic member 52, and meanwhile ensure that the end of the guide shaft 30 close to the rotating shaft 20 can always contact the guide portion 21.

[0069] In the present disclosure, when the actuator 100 is in the closed state, the guide shaft 30 is at point D in FIG. 8, and when an external force presses the rotating shaft 20, the rotating shaft 20 moves downward, and when the third step surface 213 comes into contact with the guide shaft 30 (point E in FIG. 8), the rotating shaft 20 starts to rotate under the action of the guide shaft 30 until the end of the rotating shaft 20 is separated from the third step surface 213 and comes into contact with the fourth step surface 214 under the pressure of the second elastic member 52, at which time the relative position of the guide shaft 30 is at point F in FIG. 8. After the pressing is released, the rotating shaft 20 starts to rebound under the action of the first elastic member 51 until it comes into contact with the fourth step surface 215, at which time the relative position of the guide shaft 30 and the rotating shaft 20 is at point G, and the guide shaft 30 slides from the fourth step surface 214 into the bottom of the first step surface 211 under the action of the fourth step surface 215, at which time the actuator 100 is in the open state. The relative position of the guide shaft 30 and the rotating shaft 20 is achieved by the process of D-A, which realizes the function of pressing opening. When the rotating shaft 20 is pressed again, the rotating shaft 20 starts to rotate under the guidance of the second side wall surface 216 and the circumferential surface of the guide shaft 30, and the guide shaft 30 falls into the second step surface 212 along the first step surface 211 of the rotating shaft 20 (at point B). After the pressing is released, the rotating shaft 20 starts to rebound under the action of the first elastic member 51 until it comes into contact with the second step surface 217 and slides into the third step surface 213 again (at point D), and the relative position of the guide shaft 30 and the rotating shaft 20 is achieved by the process of A-D, which realizes the function of pressing closing. The relative displacement trajectory of the rotating shaft 20 and the guide shaft 30 corresponds to the points in FIG. 8, which is D-E-F-G-A-B-C-D, and D-A is pressing opening and A-D is pressing closing. The actuator 100 can return the relative position of the guide shaft 30 and the rotating shaft 20 to the original position by two pressings and contact pressings according to the structure.

[0070] According to one embodiment of the present disclosure, a locking member 40 is further included, which is arranged in the accommodation cavity 11, and the portion of the rotating shaft 20 located in the accommodation cavity 11 is provided with a locking opening 22, and the locking member 40 can be inserted into or separated from the locking opening 22. When the locking member 40 is inserted into the locking opening 22, the actuator 100 is in the locked state, the guide shaft 30 is not movable between the first position and the second position relative to the guide portion 21, and the actuator 100 cannot be opened by pressing the rotating shaft 20. When the locking member 40 is separated from the locking opening 22, the actuator 100 is in the unlocked state, the guide shaft 30 is movable between the first position and the second position relative to the guide portion 21, and the actuator 100 can be opened or closed by pressing the rotating shaft 20.

[0071] Wherein, as shown in FIG. 2 and FIG. 4, when the guide shaft 30 is located at the first position relative to the guide part 21, the actuator 100 is in the closed state, and the locking member 40 can be inserted into or out of the lock port 22. When the locking member 40 is inserted into the lock port 22, the actuator 100 is in the locked state, and when the locking member 40 is out of the lock port 22, the actuator 100 is in the unlocked state. When the locking member 40 is inserted into the lock port 22, the guide shaft 30 is not movable between the first position and the second position relative to the guide part 21, and the user cannot drive the actuator 100 to open by pressing the rotating shaft 20. When the locking member 40 is out of the lock port 22, the actuator 100 is in the non-locked state, and the guide shaft 30 can be movable between the first position and the second position relative to the guide part 21, and the user can drive the actuator 100 to open or close by pressing the rotating shaft 20. As shown in FIG. 1 and FIG. 3, when the guide part 21 is located at the second position, the actuator 100 is in the open state, thereby quickly achieving the opening or closing of the actuator 100 in a very short stroke. By arranging the guide part 21 on the rotating shaft 20, some components can be reduced, thereby reducing the occupied space of the actuator 100. The rotating shaft 20 in the actuator 100 of the present disclosure can achieve the opening or closing of the vehicle's flap by moving or rotating.

When the guide shaft 30 is located at the first position relative to the guide part 21, the actuator 100 is in the closed state, the cam 72 drives the locking member 40 to be inserted into or out of the lock port 22, the actuator 100 is in the locked state, and the function of the electric locking is achieved, the cam 72 drives the locking member 40 to be out of the lock port 22, the actuator 100 is in the unlocked state, and the function of the electric unlocking is achieved. When the guide shaft 30 is located at the second position relative to the guide part 21, the actuator 100 is in the open state, and the function of the electric unlocking is achieved. Of course, in the present disclosure, the actuator 100 further comprises a magnetic member 74 and other structures, and other structures of the actuator 100 and their working principles are understandable and achievable for those skilled in the art, which will not be described in detail in the present disclosure.
