[0057] Figure 1 is a schematic structural diagram of one state of the electric actuator 100 according to one embodiment of the present disclosure. Figure 2 2 is a schematic structural diagram of another state of the electric actuator 100 according to an embodiment of the present disclosure. Figure 3 yes Figure 1 The schematic diagram of the electric actuator 100 in use state is shown. Figure 4 yes Figure 2 The schematic diagram of the electric actuator 100 in use state is shown.

[0058] The following will be combined Figures 1 to 4 The electric actuator 100 of the present disclosure will be described in detail.

[0059] like Figure 1 and Figure 2 As shown, the electric actuator 100 of the present disclosure includes: a housing 110, a driving device 120, a transmission component 130, and a swing arm 140 and other structures.

[0060] In the present disclosure, the housing 110 may include an upper housing and a lower housing, wherein the upper housing is Figure 1 and Figure 2 Not shown in FIG. Figure 3 and Figure 4 The upper housing is shown in FIG. The lower housing is formed with a receiving space, and the upper housing can be formed as a cover plate and at least partially close the receiving space. In actual use, the position of the electric actuator of the present disclosure can be fixed by fixing the housing 110 to the sliding door.

[0061] The driving device 120 is disposed in the housing 110, and the driving device 120 may be a motor, thereby forming the electric actuator 100 of the present disclosure, that is, when electric energy is applied to the electric actuator of the present disclosure, the driving device 120 can generate a driving force. More preferably, the motor may be a DC motor or a stepping motor, etc. Moreover, the cross section of the motor may be a circular, track-shaped, square, or other shapes.

[0062] The transmission component 130 is rotatably disposed in the housing 110. In the present disclosure, the transmission component 130 may be a helical gear or a worm gear; in this case, the output shaft of the driving device 120 is connected with a worm, and the worm can be connected to the helical gear or the worm gear. In a preferred embodiment, the rotation axis of the transmission component 130 is perpendicular or substantially perpendicular to the upper housing or perpendicular to the bottom wall of the lower housing, and accordingly, the output shaft of the driving device 120 can be parallel or substantially parallel to the bottom wall of the lower housing.

[0063] The transmission component 130 is rotated by the driving force provided by the driving device 120; wherein a protrusion 131 is provided on one side of the transmission component 130; the protrusion 131 is formed to protrude along the central axis direction of the transmission component 130. In other words, the protrusion 131 has a preset height on the transmission component 130.

[0064] In terms of quantity, the protrusion 131 of the present disclosure is provided with two, thereby making it possible for the first end 141 and the second end 142 of the swing arm 140 of the present disclosure to be provided on the same side of the transmission component 130. More specifically, the protrusion 131 and the swing arm 140 are both provided on the upper side of the transmission component 130.

[0065] In terms of position, the two protrusions 131 are symmetrically arranged along a plane passing through the central axis of the transmission component 130. In other words, the distance between the two protrusions 131 and the central axis is the same, that is, the two protrusions 131 are located on the same circumference whose center is located on the central axis, and the two protrusions 131 are located on the same diameter line, that is, the line connecting the two protrusions 131 passes through the central axis. Therefore, the protrusions 131 of the present disclosure are arranged at the radial peripheral position of the transmission component 130, and the weight is light.

[0066] like Figure 1 and Figure 2 As shown, the swing arm 140 swings through the rotation of the transmission component 130; specifically, when the motor rotates along the first direction, the swing arm 140 will swing to one side, for example, the swing arm 140 swings clockwise, and when the swing arm 140 is blocked by the first limit member 150, the swing arm 140 stops at the first position, that is, the first limit member 150 is used to limit the swing arm 140 at the first position, and at this time, the application of electric energy to the motor stops, and the motor stops rotating.

[0067] That is to say, at the moment of reaching the first position, at the first position, the protrusion 131 can apply a thrust to the swing arm 140 , so that there is a positive pressure (ie, pressure contact) between the swing arm 140 and the first limit member 150 .

[0068] And in this first position, as Figure 2 As shown, when the transmission component 130 continues to rotate counterclockwise, the protrusion 131 will be able to support the swing arm 140, and the transmission component 130 stops moving. At this time, the door lock is in the unlocked position.

[0069] Meanwhile, in the first position, the swing arm 140 can trigger the position detection structure 160, thereby enabling the position detection structure 160 to detect the position of the swing arm 140. In a specific embodiment, the position detection structure 160 can be a micro switch.

[0070] On the other hand, when the motor rotates in a second direction opposite to the first direction, the swing arm 140 will swing to the other side. Figure 2Starting from the position, the swing arm 140 will swing counterclockwise; when the swing arm 140 is blocked by the second limit member 170, the swing arm 140 stops at the second position, that is, the second limit member 170 is used to limit the swing arm 140 at the second position, at this time, the application of electric energy to the motor is stopped, and the motor stops rotating.

[0071] That is, when reaching the second position, at the second position, the protrusion 131 can apply a thrust to the swing arm 140 , so that there is a positive pressure (ie, pressure contact) between the swing arm 140 and the second limit member 170 .

[0072] And in this second position, as Figure 1 As shown, when the transmission component 130 continues to rotate clockwise, the protrusion 131 will be able to support the swing arm 140, and the transmission component 130 stops moving. At this time, the door lock is in the locked position.

[0073] In the present disclosure, the first stopper 150 and the second stopper 170 are both disposed inside the housing 110, and the first stopper 150 and the second stopper 170 are disposed to buffer the impact and reduce the noise. Moreover, since there is a certain gap between the worm and the transmission component 130, when the motor stops rotating, the transmission component 130 has a slight return motion, and the protrusion 131 and the swing arm 140 are no longer in close contact, that is, there is no positive pressure between the protrusion 131 and the swing arm 140.

[0074] In the present disclosure, the swing arm 140 includes a first end 141 and a second end 142, and the first end 141 or the second end 142 can cooperate with the protrusion 131 of the transmission component 130; that is, in different states, the first end 141 or the second end 142 can respectively cooperate with the protrusion 131 of the transmission component 130, for example, driving the rotation by the protrusion 131, or limiting the position by the protrusion 131, but the first end 141 and the second end 142 cannot cooperate with the protrusion 131 of the transmission component 130 at the same time.

[0075] More specifically, the swing arm 140 is V-shaped, and includes a swing axis, which is located at a corner of the V-shaped swing arm 140. Accordingly, the two free ends of the V-shape, i.e., the two ends of the opening of the V-shaped swing arm 140, are respectively formed as the first end 141 and the second end 142; accordingly, the first end 141 and the second end 142 are located on the same side of the transmission component 130, thereby effectively reducing the size of the electric actuator of the present disclosure, which is conducive to arranging the electric actuator in the sliding door.

[0076] In the present disclosure, the first end portion 141 includes a first end surface, and the second end portion 142 includes a second end surface, wherein the first end surface and the second end surface are both located on a cylindrical surface with the swing axis as the central axis. Figure 1 In the locked state shown, the user can manually drive the swing arm 140 to swing and make the swing arm 140 in the locked state. Figure 2 position as shown and unlock the door.

[0077] The protrusion 131 includes a first side surface 132, and the first side surface 132 of one of the protrusions 131 can contact the first end 141 and push the swing arm 140 to move; the first side surface 132 of another of the protrusions 131 can contact the second end 142 and limit the swing arm 140 to the first position.

[0078] On the other hand, the protrusion 131 includes a second side surface 133, and the second side surface 133 of one of the protrusions 131 can contact the second end 142 and push the swing arm 140 to move; the second side surface 133 of another one of the protrusions 131 can contact the first end 141 and limit the swing arm 140 to the second position.

[0079] In the present disclosure, the first side surface 132 is a curved surface convex outward, and / or the second side surface 133 is a curved surface convex outward. Thus, the first side surface 132 and the second side surface 133 can maintain line contact with the swing arm 140. Accordingly, when the toggle member 190 is manually pushed, the swing arm 140 does not contact the transmission component 130 during the movement, thereby avoiding the situation where the transmission component 130 pushes the worm in the opposite direction to cause a large resistance. That is, by separating the manual movement from the motor drive, the situation where a large force is required for manual unlocking is avoided, and the manual operation of the swing arm 140 is convenient.

[0080] More preferably, if Figure 1 and Figure 2 As shown, the electric actuator 100 further includes a manual unlocking arm 180 , wherein the manual unlocking arm 180 is connected to the swing arm 140 and has the same swing axis.

[0081] For example, an axis component is formed on the manual unlocking arm 180, and the axis of the axis component is the above-mentioned swing axis. Moreover, an external spline is formed on the outer surface of the axis component, and a spline hole is formed on the swing arm 140. Therefore, by installing the swing arm 140 on the axis component, the swing arm 140 and the manual unlocking arm 180 are synchronously transmitted and connected, and have the same swing axis.

[0082] In one embodiment, the electric actuator 100 further includes a toggle member 190, and the toggle member 190 is used to drive the manual unlocking arm 180 so that the manual unlocking arm 180 swings. Figure 3 As shown in FIG. 1 , when the toggle member 190 is horizontally translated to the right, the toggle member 190 is in a Figure 4 The state shown thereby enables the manual unlocking arm 180 to rotate, and accordingly, the door lock of the present disclosure is in an unlocked state.

[0083] In a specific embodiment, an elongated groove is provided on the manual unlocking arm 180, and at least a portion of the toggle member 190 can slide in the elongated groove, and when at least a portion of the toggle member 190 is located at different positions in the elongated groove, the manual unlocking arm 180 is also in different positions.

[0084] On the other hand, when the swing arm 140 is driven by the motor to swing, the manual unlocking arm 180 will also swing along, and the toggle member 190 will also translate accordingly, prompting the user whether the door lock is in an unlocked state or a locked state.

[0085] According to another aspect of the present disclosure, a door lock is provided, which includes the electric actuator 100 described above.

[0086] In the description of this specification, the description with reference to the terms "one embodiment / method", "some embodiments / methods", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment / method or example are included in at least one embodiment / method or example of the present application.
