[0066] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the disclosure. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the accompanying drawings.

[0067] It should be noted that, where there is no conflict, the embodiments and features described in this disclosure can be combined with each other. The technical solutions of this disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0068] Unless otherwise stated, the exemplary implementations / embodiments shown are to be understood as providing exemplary features of various details that provide ways in which the technical concepts of this disclosure can be implemented in practice. Therefore, unless otherwise stated, the features of various implementations / embodiments may be additionally combined, separated, interchanged and / or rearranged without departing from the technical concepts of this disclosure.

[0069] The use of crosshairs and / or shading in the accompanying drawings is generally used to clarify the boundaries between adjacent components. Thus, unless otherwise stated, the presence or absence of crosshairs or shading does not convey or indicate any preference or requirement for the specific material, material properties, dimensions, proportions, commonalities between the illustrated components, or any other characteristics, properties, etc., of the components. Furthermore, in the accompanying drawings, the dimensions and relative dimensions of components may be exaggerated for clarity and / or descriptive purposes. When exemplary embodiments can be implemented differently, a specific process sequence may be performed in a different order than that described. For example, two consecutively described processes may be performed substantially simultaneously or in the reverse order of their description. Furthermore, the same reference numerals denote the same components.

[0070] When a component is referred to as being "on" or "above" another component, "connected to," or "joined to" another component, the component may be directly on, directly connected to, or directly joined to the other component, or there may be intermediate components. However, when a component is referred to as being "directly on" another component, "directly connected to," or "directly joined to" another component, there are no intermediate components. Therefore, the term "connection" can refer to a physical connection, an electrical connection, etc., and may or may not have intermediate components.

[0071] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” another component or feature would subsequently be positioned “above” said other component or feature. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0072] The terminology used herein is for the purpose of describing particular embodiments and is not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms “a” and “the” are intended to include the plural forms as well. Furthermore, when the terms “comprising” and / or “including” and variations thereof are used in this specification, it indicates the presence of the stated features, integrals, steps, operations, parts, components, and / or groups thereof, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, parts, components, and / or groups thereof. It should also be noted that, as used herein, the terms “substantially,” “about,” and other similar terms are used as approximate terms rather than as terms of degree, thus explaining the inherent biases in measurements, calculated values, and / or provided values ​​that would be recognized by one of ordinary skill in the art.

[0073] Figure 1 This is a schematic diagram of the structure of a side door actuator according to one embodiment of the present disclosure. Figure 2 This is a schematic diagram of a side door actuator according to one embodiment of the present disclosure. Figure 3 yes Figure 2 A structural diagram from another angle.

[0074] like Figures 1 to 3 As shown, the side door actuator of this disclosure includes components such as a mounting bracket 100, a housing assembly 200, a drive unit 300, a lead screw 400, a lead nut 500, a push rod 600, and a control assembly 800.

[0075] In use, the side door actuator of this disclosure can be fixed by mounting the mounting bracket 100 to the vehicle door. Furthermore, the mounting bracket 100 can be fixedly connected to the vehicle door using fastening elements such as screws or anchors. In other words, the mounting bracket 100 of this disclosure is connected to the mounting features of the vehicle door via fastening elements.

[0076] Figure 4 This is a schematic diagram of the housing assembly of a side door driver according to one embodiment of the present disclosure.

[0077] like Figures 1 to 4 As shown, the housing assembly 200 of this disclosure includes a first receiving space and a second receiving space; in a preferred embodiment, the first receiving space and the second receiving space are not connected; more preferably, the first receiving space and the second receiving space both extend along the length direction of the housing assembly 200.

[0078] In a preferred embodiment, a guide structure 210 is formed inside the housing assembly 200, which guides the movement of the nut 500. In other words, the guide structure 210 can suppress the rotation of the nut 500, so that when the lead screw 400 rotates inside the nut 500, the nut 500 can move along the axial direction of the lead screw 400.

[0079] In a preferred embodiment, the guide structure 210 includes two parallel plate components. Specifically, two parallel plate components are provided on the inner wall surface of the housing assembly 200, and the length direction (extension direction) of these two plate components is the same as the axial direction of the lead screw. In this case, a portion of the nut 500 (i.e., the guide component 510 of the nut 500) can be slidably disposed between these two plate components, thereby enabling the nut 500 to be guided by the guide structure 210.

[0080] More preferably, two guide structures 210 are provided, and these two guide structures 210 are respectively located on two opposing inner wall surfaces of the housing assembly 200. Of course, multiple guide structures 210 of this disclosure may also be provided, and these guide structures 210 may be arranged in parallel.

[0081] In this disclosure, the first receiving space is located below the second receiving space, and the guide structure 210 is capable of extending into the interior of the second receiving space.

[0082] Furthermore, a guide member 220 with a groove can be provided in the guide structure 210. The guide member 220 has a groove, and the guide component 510 of the nut 500 is slidably disposed in the groove of the guide member 220. Thus, when installing the nut 500 into the housing assembly 200, the guide member 220 can be engaged with the guide component 510 of the nut 500 first, and then the guide member 220 can be installed in the guide structure 210. Accordingly, the side door actuator of this disclosure can be easily assembled. Moreover, the guide member 220 can be made of metal material to reduce the frictional resistance of the nut 500 during movement.

[0083] In this disclosure, a drive device 300 is disposed on the housing assembly 200, and the drive device 300 is capable of outputting rotational action, thereby having a rotation axis. In a specific embodiment, the drive device 300 can be a motor. The motor is preferably a DC motor, a geared motor, or a servo motor, etc. In particular, the motor may include a magnetic ring, and output a Hall signal through the magnetic ring to accurately determine the position of the motor's output shaft. Accordingly, the rotation axis of the drive device 300 is the axis of the motor's output shaft. In particular, the rotation axis of the drive device 300 can be parallel to the rotation axis of the lead screw 400.

[0084] In a preferred embodiment, the drive device 300 is disposed in the first receiving space, and the rotation axis of the drive device 300 is aligned with the length direction of the housing assembly 200.

[0085] The lead screw 400 is disposed in the second receiving space and connected to the drive device 300 via the transmission assembly 700, so that the drive device 300 can drive the lead screw 400 to rotate; that is, in the side door drive of this disclosure, the lead screw 400 is disposed above the drive device 300. Of course, the drive device 300 may also be located below the lead screw 400.

[0086] like Figures 1 to 3 As shown, the mounting bracket 100 is provided with a first support hole, and one end of the lead screw 400 is rotatably disposed in the first support hole of the mounting bracket 100. More preferably, a bearing or bushing is provided between one end of the lead screw 400 and the inner wall surface of the first support hole, thereby making the lead screw 400 rotate more smoothly.

[0087] Furthermore, the other end of the housing assembly 200 of this disclosure is provided with an end cap 900. A second support hole is provided on the end cap 900, and the other end of the lead screw 400 is rotatably disposed within the second support hole of the end cap 900. More preferably, a bearing or bushing is provided between the other end of the lead screw 400 and the inner wall surface of the second support hole, thereby allowing the lead screw 400 to rotate more smoothly.

[0088] In other words, the lead screw 400 of this disclosure is supported by the mounting bracket 100 and the end cap 900, which together limit the position of the lead screw 400 in the axial direction.

[0089] See again Figure 2 and Figure 3 The transmission assembly 700 disclosed herein may include a driving gear, an idler gear, and a driven gear. The driving gear is connected to and driven by the drive device 300. The driven gear is fixedly connected to the lead screw 400, thereby driving the lead screw 400 to rotate through the rotation of the driven gear. The idler gear meshes with the driving gear and the driven gear, thereby transmitting power from the driving gear to the driven gear.

[0090] In a preferred embodiment, the driving gear, idler gear, and driven gear are all helical gears, thereby making the power transmission process of the transmission assembly 700 of this disclosure smoother.

[0091] The end cap 900 is provided with a cover member 910. Correspondingly, the driven gear can be disposed within the cover member 910, and the position of the driven gear on the lead screw 400 can be restricted by the cover member 910. Specifically, one end of the driven gear in the axial direction can be disposed in a bearing bush in the second support hole to restrict its position, and the other end of the driven gear in the axial direction can be restricted by the cover member 910.

[0092] Furthermore, the cover member 910 has an opening where the idler gear and the driven gear are connected in transmission. Thus, the driven gear of this disclosure can be covered by the cover member 910, which improves the transmission effect and service life of the transmission assembly.

[0093] Figure 5 This is a structural schematic diagram of a mounting bracket according to one embodiment of the present disclosure. Figure 6 This is a schematic diagram of the lead screw and push rod according to one embodiment of the present disclosure.

[0094] like Figure 5 and Figure 6 As shown, the nut 500 is disposed on the lead screw 400, and the nut 500 moves along the axis of the lead screw 400 by the rotation of the lead screw 400; one end of the push rod 600 is disposed on the nut 500, and the push rod 600 can be in a retracted state and an extended state as the nut 500 moves along the axis of the lead screw 400.

[0095] The wire mother 500 disclosed herein may include a frame formed of metal material and a plastic coating layer formed on the outside of the frame, thereby giving the wire mother 500 greater strength.

[0096] Specifically, the mounting bracket 100 has a through hole, and the other end of the push rod 600 passes through the through hole, so that both ends of the push rod 600 are located on both sides of the mounting bracket 100. Thus, when the side door actuator of this disclosure is in use, the other end of the push rod 600 can be hinged to the vehicle body or hinged to the vehicle body through a support. Accordingly, when the push rod 600 is in the extended state, the door can be in the open state, and when the push rod 600 is in the retracted state, the door can be in the closed state.

[0097] In a preferred embodiment, a limiting member 610 is provided on the push rod 600. The limiting member 610 is used to cooperate with the mounting bracket 100 to limit the maximum extension length of the push rod 600. The surface of the limiting member 610 that contacts the mounting bracket 100 is set as an arc surface. The mounting bracket 100 includes a blocking member 110, and the contact surface between the blocking member 110 and the limiting member 610 is an arc surface.

[0098] More preferably, the arc surface of the limiting member 610 is a cylindrical surface, and the center line of the cylindrical surface is perpendicular or substantially perpendicular to the plane in which the push rod 600 moves. Similarly, the arc surface of the blocking member 110 is also a cylindrical surface, and the center line of the cylindrical surface is perpendicular or substantially perpendicular to the plane in which the push rod 600 moves. Moreover, the cylindrical surfaces of the limiting member 610 and the blocking member 110 have approximately the same diameter. Therefore, when the limiting member 610 contacts the blocking member 110, regardless of the orientation of the push rod 600, there can be a large contact area between the limiting member 610 and the blocking member 110, thereby preventing damage to the limiting member 610 and the blocking member 110.

[0099] In this disclosure, the control component 800 includes a housing structure 810 and a control circuit board (i.e., a motor controller) disposed within the housing structure 810. The housing structure 810 is fixedly connected to the housing assembly 200. Therefore, the side door driver of this disclosure can integrate the motor controller, eliminating the need for a separate space on the door for its installation. Furthermore, when the side door driver of this disclosure is installed on the door, a separate motor controller is not required, simplifying the installation process. Additionally, the side door driver of this disclosure has a compact structure and lower cost.

[0100] Figure 7 This is a schematic diagram of the structure of a wire mother according to one embodiment of the present disclosure. Figure 8 This is a schematic diagram of a ball joint according to one embodiment of the present disclosure.

[0101] like Figure 7 and Figure 8 As shown, one end of the push rod 600 is connected to the nut 500 via a ball joint. Specifically, the lower end of the nut 500 of this disclosure has a protrusion 520; wherein, the protrusion 520 can be formed in a cylindrical shape. And a threaded hole is formed at the center of the protrusion 520.

[0102] The spherical member 530 has a central hole. In a preferred embodiment, the central hole can be a cylindrical hole, so that the protrusion 520 can be inserted into the central hole of the spherical member 530, and the lower end of the protrusion 520 is higher than the lower end of the spherical member 530.

[0103] At least a portion of the stop 540 is inserted into the central hole of the spherical member 530, and the lower end of the stop 540 has an outer flange with a diameter larger than the inner diameter of the lower end of the spherical member 530, thereby enabling the stop 540 to press against the spherical member 530. Specifically, a screw 550 can pass through the stop 540 and the spherical member 530 and be screwed into the threaded hole of the protrusion 520 to fix the stop 540 and the spherical member 530 to the nut 500.

[0104] In this disclosure, the outer peripheral surface of the spherical member 530 is formed as a spherical surface, thereby enabling the spherical member 530 to be formed as a spherical head. Correspondingly, the outer surface of the spherical member 530 is provided with a first hemispherical recess 560 and a second hemispherical recess 570; wherein the first hemispherical recess 560 and the second hemispherical recess 570 form a spherical recess structure as a whole, that is, the inner surfaces of the first hemispherical recess 560 and the second hemispherical recess 570 are both formed as spherical surfaces. Moreover, at least a portion of the outer surface of the first hemispherical recess 560 and the second hemispherical recess 570 is formed as a cylindrical surface, and a mounting hole is provided at one end of the push rod 600, with at least a portion of the first hemispherical recess 560 and the second hemispherical recess 570 located within the mounting hole.

[0105] In this disclosure, the housing assembly 200 includes a first connector 230, and the housing structure 810 includes a second connector 820, with the first connector 230 and the second connector 820 being plugged into each other. Additionally, the first connector 230 is connected to the motor via a wire to increase vibration absorption. Furthermore, the housing structure 810 may also include a third connector 830, through which the side door actuator of this disclosure is connected to the vehicle controller, so as to drive the motor to rotate a preset angle using control signals and current provided by the vehicle controller.

[0106] Furthermore, the control circuit board of this disclosure is connected to the second connector 820 and the third connector 830 respectively via wires to increase the ability to absorb vibration, so that the vibration of the vehicle is transmitted to the control circuit board as little as possible.

[0107] In a preferred embodiment, the housing structure 810 is formed as a sealed space, and the control circuit board is disposed within the sealed space. This prevents liquids and dust from entering the interior of the housing structure 810 and causing damage to the control circuit board. In other words, the housing structure 810 of this disclosure may include a waterproof structure to improve the service life of the control circuit board.

[0108] In this disclosure, the control circuit board can be connected to the vehicle controller via a CAN bus or LIN bus to enable communication between the control circuit board and the vehicle controller.

[0109] The housing assembly 200 is provided with a mounting component 240 for connecting to the vehicle door. Thus, in the side door drive of this disclosure, it is connected to the vehicle door not only through the mounting bracket 100, but also through the mounting component 240, thereby increasing the firmness of the connection between the side door drive and the vehicle door.

[0110] According to another aspect of this disclosure, a vehicle is provided that includes the aforementioned side door actuator.
