[0048] The actuator 100 according to the embodiment of the present utility model is described in detail below with reference to the accompanying drawings.

[0049] like Figures 1 to 5As shown, the actuator 100 according to the embodiment of the present invention includes a housing 10 , a rotating shaft 20 , and a guide shaft 30 .

[0050] Specifically, a housing 10 is provided with a housing cavity. The rotating shaft 20 is movably provided on the housing 10 along a first direction, and a part of the rotating shaft 20 is located in the housing cavity, and the rotating shaft 20 is rotatable relative to the housing 10. The guide shaft 30 is provided in the housing cavity along a second direction, and a guide portion 21 is provided on a side of the rotating shaft 20 facing the guide shaft 30, and the guide portion 21 is in contact with the guide shaft 30. When the rotating shaft 20 is pressed, the guide shaft 30 cooperates with the guide portion 21 to rotate the rotating shaft 20, so that the guide shaft 30 is movable between a first position and a second position relative to the guide portion 21. When the guide shaft 30 is located in the first position relative to the guide portion 21, the actuator 100 is in a closed state, and when the guide shaft 30 is located in the second position relative to the guide portion 21, the actuator 100 is in an open state.

[0051] In other words, if Figure 1 and Figure 2 As shown, the actuator 100 according to the embodiment of the utility model is mainly used to control the opening or closing of a cover in a vehicle, and the vehicle cover can be a cover structure such as a charging cover, a fuel filler cover or a storage box cover on the vehicle. The actuator 100 of the utility model is mainly composed of a housing 10, a rotating shaft 20 and a guide shaft 30. Figure 3 and Figure 4 As shown, a housing cavity is provided in the housing 10. The rotating shaft 20 can move along a first direction, the rotating shaft 20 is mounted on the housing 10, and a part of the rotating shaft 20 extends into the housing cavity, and the rotating shaft 20 is rotatable relative to the housing 10. When the user presses the rotating shaft 20, the rotating shaft 20 can rotate in the housing 10. The guide shaft 30 is installed in the housing cavity 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 a vertical direction, and the guide shaft 30 is installed in the housing 10 along a horizontal direction, and the end of the rotating shaft 20 abuts against the end of the guide shaft 30.

[0052] like Figure 5As shown, a guide portion 21 is provided on the side of the rotating shaft 20 facing the guide shaft 30. When the user presses the rotating shaft 20, the guide portion 21 of the rotating shaft 20 is always in contact with the guide shaft 30. When the rotating shaft 20 is pressed, the guide shaft 30 cooperates with the guide portion 21 to rotate the rotating shaft 20, so that the guide shaft 30 is movable between the first position and the second position relative to the guide portion 21. 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 rotation direction, ensuring that the rotating shaft 20 can rotate in the set direction, and by providing 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, ensuring that the actuator 100 can achieve functions such as press-to-open or press-to-close in a very small installation space.

[0053] Therefore, according to the actuator 100 of the embodiment of the utility model, by setting the guide part 21 on the rotating shaft 20, the guide part 21 is in contact with the guide shaft 30. When the rotating shaft 20 is pressed, the guide shaft 30 switches between the first position and the second position relative to the guide part 21, which greatly simplifies the complexity of the actuator 100, effectively reduces the parts of the actuator 100, and is conducive to the miniaturized design of the overall structure of the actuator 100, ensuring that the actuator 100 can achieve functions such as pressing to open or close in a very small installation space.

[0054] According to one embodiment of the utility model, the guide portion 21 includes a plurality of step surfaces, and the plurality of step surfaces form a height difference in the radial direction of the rotating shaft 20. When the rotating shaft 20 is pressed, the rotating shaft 20 rotates, and the guide shaft 30 can contact the plurality of step surfaces respectively, so that the guide shaft 30 can switch between the first position and the second position relative to the guide portion 21.

[0055] In other words, Figure 7 As shown, the guide portion 21 is mainly composed of a plurality of step surfaces, wherein the plurality of step surfaces form a step structure with a height difference in the radial direction of the rotating shaft 20. When the rotating shaft 20 is pressed, the rotating shaft 20 rotates, and the plurality of step surfaces can contact the guide shaft 30 respectively. During the rotation of the rotating shaft 20, the guide shaft 30 switches between the first position and the second position relative to the guide portion 21, ensuring that the actuator 100 can realize functions such as push-to-open within a very short pressing stroke.

[0056] According to one embodiment of the utility model, the plurality of step surfaces include: a first step surface 211, a second step surface 212, a third step surface 213, and a fourth step surface 214. The first step surface 211, the second step surface 212, the third step surface 213, and the fourth step surface 214 are sequentially distributed along the circumference of the guide shaft 30. When the guide shaft 30 is in contact with the third step surface 213, the guide shaft 30 is in a first position relative to the guide portion 21, and the actuator 100 is in a closed state; when the guide shaft 30 is in contact with the first step surface 211, the guide shaft 30 is in a second position relative to the guide portion 21, and the actuator 100 is in an open state.

[0057] That is, see Figure 7 The plurality of step surfaces are mainly composed of a first step surface 211, a second step surface 212, a third step surface 213 and a fourth step surface 214, wherein the first step surface 211, the second step surface 212, the third step surface 213 and the fourth step surface 214 are sequentially distributed relative to the circumference of the guide shaft 30. 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 at this time, the actuator 100 is in the closed state.

[0058] 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 a closed state. At this time, the locking member 40 can be inserted into or disengaged from the lock port 22. When the locking member 40 is inserted into the lock port 22, the actuator 100 is in a locked state, and the guide shaft 30 is immovable between the first position and the second position relative to the guide portion 21, and the actuator 100 cannot be driven to open by pressing the rotating shaft 20; when the locking member 40 is disengaged from the lock port 22, the actuator 100 is in an unlocked state, and 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 driven to open or close 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 an open state.

[0059] In the present invention, 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 rotation direction of the rotating shaft 20 is improved, ensuring that the rotating shaft 20 can rotate in the set direction, greatly reducing the pressing stroke of the actuator 100, which is conducive to the miniaturization design of the overall structure of the actuator 100, and ensuring that the actuator 100 can achieve functions such as press-to-open within a very short pressing stroke.

[0060] According to one embodiment of the utility model, when the actuator 100 is switched from a closed state to an open state, the guide shaft 30 rotates 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 an open state to a closed state, the guide shaft 30 rotates from the first step surface 211 to the second step surface 212 and the third step surface 213 relative to the guide portion 21.

[0061] That is to say, Figure 7 As shown, when the rotating shaft 20 is pressed, when the actuator 100 switches from the closed state to the open state, the guide shaft 30 can rotate 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 switches from the open state to the closed state, the guide portion 21 can rotate from the first step surface 211 to the second step surface 212 and 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 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 inserted into the lock port 22, the actuator 100 is in the unlocked state.

[0062] According to one embodiment of the utility model, 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 its radial direction 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 part 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, and the height of the second step surface 21 in the radial direction of the rotating shaft 20 is higher than part of the fourth step surface 214. Of course, the rotating shaft 20 may further include a first side wall surface 215 , and the first side wall surface 215 is a connecting surface between the fourth step surface 214 and the outer wall surface 219 of the rotating shaft 20 .

[0063] In other words, Figure 7As shown, 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 surface formed by the height difference is recorded as the second side wall surface 216. The height of the outer wall surface 219 of the rotating shaft 20 in the radial direction 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 surface formed by the height difference is recorded as the second table surface 217. The first step surface 211 is higher than the second step surface 212 and the third step surface 213 in the radial direction of the rotating shaft 20 at a location close to 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 surface formed by the height difference is recorded as the third table surface 218. The height of the second step surface 212 in the radial direction of the rotating shaft 20 is higher than that of the third step surface, and the height of the second step surface 212 and the third step surface 213 in the radial direction of the rotating shaft 20 near the fourth step surface 214 is higher than that of the fourth step surface 214. In other words, the height of the second step surface 212 in the radial direction of the rotating shaft 20 is higher than that of the fourth step surface 214, and 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 its radial direction is higher than that of the first step surface 211 and the fourth step surface 214.

[0064] The outer wall surface 219 of the rotating shaft 20 forms a second side wall surface 216 and a 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 the first step surface 211 and the fourth step surface 214. In the process of pressing the rotating shaft 20, the guide shaft 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 rotation direction, ensure that the rotating shaft 20 can rotate in the set direction, greatly reduce the pressing stroke of the actuator 100, and facilitate the miniaturization design of the overall structure of the actuator 100, so as to ensure that the actuator 100 can realize the functions of pressing to open or close in a very small installation space.

[0065] According to one embodiment of the utility model, Figure 7As shown, the first step surface 211 and the fourth step surface 214 form an inclined surface with an inclination angle. By setting the first step surface 211 and the fourth step surface 214 as inclined surfaces with an inclination 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 return the relative position of the guide shaft 30 and the rotating shaft 20 to the original position by pressing twice or contact pressing according to the structural design of the guide part 21.

[0066] According to one embodiment of the utility model, Figure 7 As shown, 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 where it connects 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 where it connects 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 where it connects 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 where it connects with the first step surface 211. The actuator 100 can return the relative position of the guide shaft 30 and the rotating shaft 20 to the original position by pressing twice or contact pressing according to the structural design of the guide part 21. .

[0067] According to an embodiment of the present invention, a first elastic member 51 is disposed in the rotating shaft 20 . The first elastic member 51 extends along the axial direction of the rotating shaft 20 , and the first elastic member 51 abuts against the inner cavity end surface of the rotating shaft 20 .

[0068] That is to say, Figure 5 As shown, a first elastic member 51 is provided in the rotating shaft 20, and the first elastic member 51 can be a spring or a compression spring. The first elastic member 51 extends along the axial direction of the rotating shaft 20, and the first elastic member 51 abuts against the inner cavity end face of the rotating shaft 20. The rotating shaft 20 can be moved along its own longitudinal axis direction in the housing 10 of the actuator 100 by the force of the first elastic member 51, thereby providing a restoring force for the rotational reset of the rotating shaft 20. And 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 through the reaction force provided by the guide shaft 30, thereby driving the rotating shaft 20 to rotate. At the same time, by setting the guide portion 21, the certainty of the rotating shaft 20 in the rotation direction can be improved, ensuring that the rotating shaft 20 can rotate in the set direction.

[0069] According to an embodiment of the present invention, a shaft sleeve 60 is disposed on the outer circumferential surface of the guide shaft 30 , and a second elastic member 52 is disposed on one end of the guide shaft 30 away from the rotating shaft 20 .

[0070] In other words, Figure 6 As shown, a sleeve 60 is installed on the outer circumferential surface of the guide shaft 30, and a second elastic member 52 is provided on one end of the guide shaft 30 away from the rotating shaft 20. The second elastic member 52 is a spring or a compression spring, and the guide shaft 30 is installed in the 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 keep the guide shaft 30 in contact with the surface of the rotating shaft 20.

[0071] In the present utility model, if Figure 1 and Figure 2 As shown, the sleeve 60 is installed and fixed in the housing 10 and fixed by the upper cover 73 to limit the moving track of the guide shaft 30. By adding the second elastic member 52 for adjusting the telescopic length of the guide shaft 30, the pressing force and the stress of the components inside the actuator 100 are reduced. At the same time, the structural design of setting a torsion spring outside the rotating shaft 20 to drive the rotating shaft 20 to rotate in the prior art is eliminated, and the overall structure is simpler and more compact, which is conducive to the miniaturization design of the actuator 100.

[0072] According to one embodiment of the utility model, Figure 6 As shown, 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, which facilitates the installation of the second elastic member 52 and ensures that the end of the guide shaft 30 close to the rotating shaft 20 can always contact the guide part 21.

[0073] In the present invention, when the actuator 100 is in the closed state, the guide shaft 30 is in the position Figure 8 When the external force presses the rotating shaft 20, the rotating shaft 20 moves downward, and when the third table 218 contacts the guide shaft 30 ( Figure 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 contacts the fourth step surface 214 under the pressure of the second elastic member 52. At this time, the relative position of the guide shaft 30 is Figure 8Point F. After the pressure is released, the rotating shaft 20 begins to rebound under the action of the first elastic member 51 until it contacts the fourth table 215. At this time, the relative position of the guide shaft 30 and the rotating shaft 20 is at point G. Under the action of the fourth table 215, the guide shaft 30 slides from the fourth step surface 214 to the bottom of the first step surface 211. At this time, the actuator 100 is in an open state. The relative position of the guide shaft 30 and the rotating shaft 20 realizes the press-to-open function by the DA process. When the rotating shaft 20 is pressed again, the rotating shaft 20 begins to rotate under the guidance of its 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 (point B position). After the pressing is released, the rotating shaft 20 begins to rebound under the action of the first elastic member 51 until it contacts the second table surface 217 and slides into the third step surface 213 again (point D). The relative position of the guide shaft 30 and the rotating shaft 20 realizes the function of pressing and closing by the process AD. The relative displacement trajectory of the rotating shaft 20 and the guide shaft 30 corresponds to Figure 8 Each point of DEFGABCD is a reciprocating cycle, DA is pressed to open, and AD is pressed to close. According to this structure, the actuator 100 can return the relative position of the guide shaft 30 and the rotating shaft 20 to the original position through two pressing and contact pressing.

[0074] According to an embodiment of the utility model, it further includes a locking member 40, which is disposed in the accommodating cavity. The portion of the rotating shaft 20 located in the accommodating cavity is provided with a locking opening 22, and the locking member 40 can be inserted into or disengaged from the locking opening 22. When the locking member 40 is inserted into the locking opening 22, the actuator 100 is in a locked state, and the guide shaft 30 cannot move between the first position and the second position relative to the guide portion 21, and the actuator 100 cannot be driven to open by pressing the rotating shaft 20. When the locking member 40 is disengaged from the locking opening, the actuator 100 is in a non-locked state, and the guide shaft 30 can move between the first position and the second position relative to the guide portion 21, and the actuator 100 can be driven to open or close by pressing the rotating shaft 20;

[0075] , among which, Figure 2 and Figure 4As shown, when the guide shaft 30 is in the first position relative to the guide portion 21, the actuator 100 is in a 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 a locked state, and when the locking member 40 is inserted into the lock port 22, the actuator 100 is in an unlocked state. The guide shaft 30 is immovable between the first position and the second position relative to the guide portion 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, the actuator 100 is in an unlocked state, and the guide shaft 30 can be movable between the first position and the second position relative to the guide portion 21, and the user can drive the actuator 100 to open or close by pressing the rotating shaft 20. As shown Figure 1 and Figure 3 As shown, when the guide portion 21 is located at the second position, the actuator 100 is in an open state, so that the actuator 100 can be quickly opened or closed within a very short stroke. By arranging the guide portion 21 on the rotating shaft 20, some parts can be reduced, thereby reducing the occupied space of the actuator 100. The rotating shaft 20 in the actuator 100 of the utility model can realize the opening or closing of the vehicle cover by moving or rotating.

When the guide shaft 30 is located at the first position relative to the guide portion 21, the actuator 100 is in a closed state, the cam 72 drives the locking member 40 to insert into or disengage from the lock 22, the actuator 100 is in a locked state, and the function of electric locking is realized; the cam 72 drives the locking member 40 to disengage from the lock 22, the actuator 100 is in an unlocked state, and the function of electric unlocking is realized. When the guide shaft 30 is located at the second position relative to the guide portion 21, the actuator 100 is in an open state, and the function of electric unlocking is realized. Of course, in the present utility model, the actuator 100 also includes structures such as a magnetic member 74. For those skilled in the art, other structures and working principles of the actuator 100 are understandable and can be realized, and will not be described in detail in the present utility model.

[0077] In summary, according to the actuator 100 of the embodiment of the utility model, by setting the guide part 21 on the rotating shaft 20, the guide part 21 contacts the guide shaft 30, when the rotating shaft 20 is pressed, the guide shaft 30 switches between the first position and the second position, thereby improving the certainty of the rotating shaft 20 in the rotation direction, ensuring that the rotating shaft 20 can rotate in the set direction, greatly reducing the pressing stroke of the actuator 100, and facilitating the miniaturization design of the overall structure of the actuator 100, ensuring that the actuator 100 can realize functions such as pressing to open or close within a very short pressing stroke. At the same time, by adding a second elastic member 52 for adjusting the telescopic length of the guide shaft 30, the pressing force and the stress of the internal components of the actuator 100 are reduced. At the same time, the structural design of setting a torsion spring outside the rotating shaft 20 to drive the rotating shaft 20 to rotate in the prior art is cancelled, and the overall structure is simpler and more compact, which is conducive to the miniaturization design of the actuator 100.
