Detailed Implementation

[0032] 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.

[0033] 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.

[0034] 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.

[0035] Figure 1 This is a schematic diagram of the structure of a side door driver 100 according to one embodiment of the present disclosure. Figure 2 This is a schematic diagram of the side door driver 100 after removing the mounting housing according to one embodiment of the present disclosure.

[0036] like Figure 1 and Figure 2 As shown, the side door actuator 100 of this disclosure can be installed on the side door of a vehicle during use. The side door actuator 100 can be hinged to the vehicle body, so that when the side door actuator 100 is activated, the side door of the vehicle can be opened or closed.

[0037] Specifically, the side door actuator 100 disclosed herein may include components such as a housing, a drive element 109, a transmission assembly 110, a lead screw 120, and a lead screw 130.

[0038] The housing of this disclosure is formed in a segmented structure. Specifically, the housing of this disclosure includes three parts, namely, a mounting housing 101, an intermediate housing 102, and a tail housing 103. One end of the mounting housing 101 is used to connect to the side door, and the entire side door actuator 100 is fixed by fixing the mounting housing 101 to the side door. The other end of the mounting housing 101 is fixedly connected to one end of the intermediate housing 102, and the other end of the intermediate housing 102 is fixedly connected to the tail housing 103. The mounting housing 101, the intermediate housing 102, and the tail housing 103 of this disclosure are arranged along the axial direction of the lead screw 130.

[0039] Of course, those skilled in the art should know that the side door actuator 100 of this disclosure can also be installed on the vehicle body and connected to the side door, thereby realizing the opening or closing of the side door.

[0040] The drive element 109 can be fixed to the housing and used to provide driving force; in a specific embodiment, the drive element 109 can be selected as a motor, which can be a DC motor, a servo motor or a geared motor, etc., and the motor can use a 12V DC power supply so that the side door drive 100 of this disclosure can be easily connected to the low voltage power supply of the vehicle.

[0041] Figure 3 This is a schematic diagram of a side door actuator according to one embodiment of the present disclosure, where the mounting housing and bellows are removed. Figure 4 This is a cross-sectional structural schematic diagram of a side door actuator according to one embodiment of the present disclosure. Figure 5 This is a schematic diagram of the structure of the drive element of a side door driver according to one embodiment of the present disclosure.

[0042] Specifically, the drive element 109 of this disclosure can be fixed to the intermediate housing 102, thereby enabling the drive element 109 of this disclosure to conveniently transmit power to components such as the nut 120.

[0043] The transmission assembly 110 receives the driving force provided by the drive element 109 and transmits the driving force to components such as the nut 120, causing the nut 120 to rotate. In a specific embodiment, such as Figure 5As shown, in a specific embodiment of this disclosure, the transmission assembly 110 may include a worm gear 111 and a driven gear 112; wherein, the worm gear 111 is connected to the drive element 109, for example, the worm gear 111 can be connected to the output shaft of the drive element 109 to receive the driving force provided by the drive element 109, and the driven gear 112 is drivenly connected to the worm gear 111 to drive the driven gear 112 to rotate through the rotation of the worm gear 111. In a preferred embodiment, the driven gear of this disclosure may be a helical gear.

[0044] A lead screw nut 120 is disposed on and driven to rotate by the transmission assembly 110. A lead screw 130 cooperates with the lead screw nut 120 so that when the lead screw nut 120 is driven and rotated by the transmission assembly 110, the lead screw 130 can move axially (i.e., along the length of the lead screw 130) relative to the lead screw nut 120. One end of the lead screw 130 is hinged to a mounting bracket 104, which can be mounted on the vehicle body so that when the lead screw 130 moves along its length, i.e., when the lead screw 130 extends or retracts, the side door can be opened or closed.

[0045] In other words, the nut 120 of this disclosure is sleeved on the lead screw 130. Since the lead screw 130 does not rotate when the mounting bracket 104 is fixed to the vehicle body, the rotation of the nut 120 can cause the lead screw 130 to move along its length.

[0046] See again Figure 4 The side door actuator 100 disclosed herein also includes a bellows 105. One end of the bellows 105 can be sleeved on the lead screw 130 and fixed to one end of the connecting mounting bracket 104 of the lead screw 130. The other end of the bellows 105 is formed into an outer flange shape. At this time, the outer flange shape of the bellows 105 can be disposed between the mounting housing 101 and the intermediate housing 102. Thus, the bellows 105 can not only achieve a seal between the mounting housing 101 and the intermediate housing 102, but also shield the lead screw 130, so that the lead screw 130 will not accumulate dust and cause the nut 120 to be unable to rotate on the lead screw 130.

[0047] When the driven gear 112 of this disclosure rotates, it has a rotation axis, which can also be referred to as the rotation axis of the transmission assembly 110. The lead screw nut 120 also has a rotation axis when it rotates. The rotation bearing of the lead screw nut 120 can coincide with the rotation axis of the driven gear 112, or it can have a different included angle with the rotation axis of the driven gear 112. In other words, while rotating with the driven gear 112, the lead screw nut 120 of this disclosure can oscillate relative to the driven gear 112. Therefore, the lead screw 130 of this disclosure has a degree of oscillation freedom to match the opening angle of the side door.

[0048] The driven gear 112 of this disclosure is rotatably disposed in the intermediate housing 102, that is, the driven gear 112 of this disclosure is disposed in the intermediate housing 102. In addition, the lead screw 130 of this disclosure can pass through the intermediate housing 102, at least a portion of which (the end connected to the mounting bracket) is located in the mounting housing 101, and at least a portion of which (the free end) is located in the tail housing 103.

[0049] The tail end housing 103 of this disclosure is configured to allow the free end of the lead screw 130 to swing within it without touching the inner wall of the tail end housing 103. Furthermore, one end of the tail end housing 103 is fixedly connected to the other end of the intermediate housing 102 via a sealing gasket, and the other end of the tail end housing 103 is closed. Thus, the tail end housing 103 of this disclosure allows the lead screw 130 to operate in a substantially sealed environment, thereby preventing dust accumulation on the lead screw 130.

[0050] In order to enable the nut 120 to rotate relative to the driven gear 112, the outer peripheral surface of the nut 120 of this disclosure is formed into a spherical shape; similarly, the inner peripheral surface of the connector 140 is formed into a spherical shape, and the connector 140 is disposed outside the nut 120, thereby enabling the nut 120 to move relative to the connector 140.

[0051] In other words, the nut 120 of this disclosure will not directly contact the driven gear 112. At this time, the driven gear 112 can transmit power to the nut 120 through the connector 140.

[0052] In addition, to realize the power transmission between the connector 140 and the nut 120, the nut 120 of this disclosure has a first receiving groove 121 on its outer peripheral surface; the connector 140 has a second receiving groove 141 on its inner surface; at least a portion of the spherical element 150 (which may also be referred to as a steel ball or a ball bearing, etc.) is located in the first receiving groove 121 and at least a portion of the spherical element 150 is located in the second receiving groove 141, so that the connector 140 can transmit power to the nut 120 through the spherical element 150 and cause the nut 120 to rotate relative to the lead screw 130.

[0053] Figure 6 This is a schematic diagram of the lead screw of a side door actuator according to one embodiment of the present disclosure. Figure 7 This is a schematic diagram of the structure of the wire nut of a side door actuator according to one embodiment of the present disclosure. Figure 8 This is a schematic diagram of the connector of a side door driver according to one embodiment of the present disclosure. Figure 9 This is an exploded structural diagram of the connector and nut of a side door driver according to one embodiment of the present disclosure. Figure 10This is a schematic diagram of the connector and nut of a side door driver according to one embodiment of the present disclosure from another angle. Figure 11 This is a schematic diagram of the connector according to one embodiment of the present disclosure.

[0054] like Figures 6 to 11 As shown, the first receiving groove 121 is formed as an elongated groove with a semi-circular cross-section, and the second receiving groove 141 is a hemispherical groove. Therefore, the outer diameter of the spherical element 150 is the same as the inner diameter of the hemispherical groove of the second receiving groove 141. At this time, half of the spherical element 150 is located within the hemispherical groove and positioned by it. Thus, the other half of the spherical element 150 can be located within the elongated groove and can slide within it.

[0055] The length direction of the elongated groove is the axial direction of the nut 120. In other words, the elongated groove of this disclosure is generally arc-shaped, and the chord of the arc-shaped elongated groove can be parallel to the axial direction of the nut.

[0056] See again Figures 6 to 11 The connector 140 disclosed herein includes a first connector 142 and a second connector 143, the first connector 142 and the second connector 143 being interconnected, a portion of a second receiving groove 141 being formed in the first connector 142, and a portion of the second receiving groove 141 being formed in the second connector 143.

[0057] In other words, the connection surfaces of the first connector 142 and the second connector 143 of this disclosure are perpendicular to the axis of the connector 140.

[0058] In one specific embodiment, a first transmission protrusion 142A is formed on the outer peripheral surface of the first connector 142, and a protrusion portion is formed on the first transmission protrusion 142A; a second transmission protrusion 143A is formed on the outer peripheral surface of the second connector 143, and a recess portion is formed on the outer peripheral surface of the second transmission protrusion 143A. The protrusion portion of the first connector 142 is inserted into the recess portion of the second transmission protrusion 143A. Thus, the first connector 142 and the second connector 143 of this disclosure can engage with each other and rotate together.

[0059] Furthermore, the first transmission protrusion 142A and the second transmission protrusion 143A of this disclosure can be located on a straight line parallel to the axis of the connector 140. In this case, the first transmission protrusion 142A and the second transmission protrusion 143A can be equivalent to the teeth of an external spline. When the connector 140 is disposed inside the driven gear 112, the first transmission protrusion 142A and the second transmission protrusion 143A can be located in the tooth groove of the internal spline of the driven gear 112. Thus, the first transmission protrusion 142A and the second transmission protrusion 143A of this disclosure can play the role of power transmission.

[0060] A portion of the second receiving groove 141 is formed on the inner wall of the first connecting member 142 corresponding to the first transmission protrusion 142A; a portion of the second receiving groove 141 is formed on the inner wall of the second connecting member 143 corresponding to the second transmission protrusion 143A. Thus, the second receiving groove 141 of this disclosure is formed at a position where the radial dimension of the first connecting member 142 and the second connecting member 143 is larger, thereby allowing the first connecting member 142 and the second connecting member 143 of this disclosure to be configured as thin as possible, and further, the volume of the side door actuator 100 of this disclosure can be reduced. In a preferred embodiment, the first transmission protrusion 142A and the second transmission protrusion 143A can be configured as one set, two sets, or four sets.

[0061] See again Figure 4 and Figure 6 The first connecting member 142 of this disclosure is provided with a first bearing 144, and the second connecting member 143 is provided with a second bearing 145. Both the first bearing 144 and the second bearing 145 are supported on the inner wall of the intermediate housing 102. Moreover, the inner ring of the second bearing 145 stops on the second connecting member 143 and the driven gear 112, and the outer ring of the second bearing 145 stops on the stepped portion of the inner wall of the intermediate housing 102; the inner ring of the first bearing 144 stops on the second connecting member 143 and the driven gear 112, and the outer ring of the first bearing 144 is positioned by the mounting housing 101, so that the first connecting member 142, the second connecting member 143, and the driven gear 112 of this disclosure will not move relative to each other in the axial and circumferential directions.

[0062] Figures 12 to 14 This is a schematic diagram of the connector and nut according to another embodiment of the present disclosure.

[0063] like Figures 12 to 14 As shown in this disclosure, the connecting surfaces of the first connector 142 and the second connector 143 are parallel to the axis of the connector 140.

[0064] In one specific embodiment, a first transmission protrusion 142A is formed on the outer peripheral surface of the first connector 142; a second transmission protrusion 143A is formed on the outer peripheral surface of the second connector 143. Both the first transmission protrusion 142A and the second transmission protrusion 143A can serve as independent teeth of an external spline. When the connector 140 is disposed inside the driven gear 112, the first transmission protrusion 142A and the second transmission protrusion 143A can be located in the tooth groove of the internal spline of the driven gear 112. Thus, the first transmission protrusion 142A and the second transmission protrusion 143A of this disclosure can play the role of power transmission.

[0065] In a preferred embodiment, both the first transmission protrusion 142A and the second transmission protrusion 143A are provided as one.

[0066] See again Figure 12 and Figure 14 The first connector 142 and the second connector 143 of this disclosure are fitted with a first bearing at one axial end and a second bearing at the other axial end, thereby rotatably supporting the connector 140 and the driven gear 112 through the first bearing and the second bearing.

[0067] Figure 15 and Figure 16 This is a structural schematic diagram of a connector and a nut according to yet another embodiment of the present disclosure.

[0068] like Figure 15 and Figure 16 As shown in this disclosure, the connecting surfaces of the first connector 142 and the second connector 143 are parallel to the axis of the connector 140.

[0069] In one specific embodiment, a first transmission protrusion 142A is formed on the outer peripheral surface of the first connector 142; a second transmission protrusion 143A is formed on the outer peripheral surface of the second connector 143. Both the first transmission protrusion 142A and the second transmission protrusion 143A can serve as independent teeth of an external spline. When the connector 140 is disposed inside the driven gear 112, the first transmission protrusion 142A and the second transmission protrusion 143A can be located in the tooth groove of the internal spline of the driven gear 112. Thus, the first transmission protrusion 142A and the second transmission protrusion 143A of this disclosure can play the role of power transmission.

[0070] In a preferred embodiment, both the first transmission protrusion 142A and the second transmission protrusion 143A are provided as one.

[0071] The first connector 142 and the second connector 143 of this disclosure are fitted with a first bearing at one axial end and a second bearing at the other axial end, thereby rotatably supporting the connector 140 and the driven gear 112 through the first bearing and the second bearing.

[0072] See again Figure 15 and Figure 16 The first receiving groove 121 is formed as a hemispherical groove, and the second receiving groove 141 is formed as a long strip groove with a semi-circular cross-section. The length direction of the long strip groove is the axial direction of the connector 140.

[0073] Figures 17 to 18 This is a schematic diagram of the structure of a side door actuator according to another embodiment of the present disclosure.

[0074] like Figure 17 and Figure 18As shown, the transmission assembly 110 of this disclosure may include: a driving gear 114, an intermediate gear set 115, an idler gear 116, and a driven gear 112; thus, the transmission assembly 110 of this disclosure has a compact layout and can reduce the number of gears, reduce costs, reduce gear backlash accumulation, and improve performance.

[0075] Specifically, the driving gear 114 can be a large helical gear, which can be fixed on the rotating shaft of the driving element 109. The driving gear 114 is connected to the first gear of the intermediate gear set 115. The first gear rotates synchronously with the second gear of the intermediate gear set 115. The second gear is connected to the idler gear 116. The idler gear 116 is connected to the driven gear 112. At this time, the driving element 109 will be able to drive the driven gear 112 to rotate.

[0076] In addition, the transmission component 110 of this disclosure adopts parallel gear transmission, which is more compact and space-saving than the worm gear mechanism in the prior art. Furthermore, the left and right doors can use the same actuator. In the case of a worm gear mechanism, the left and right doors must be mirror images, which increases the mold cost. This disclosure eliminates the need for mirror images, thus reducing costs.

[0077] According to another aspect of this disclosure, a vehicle is provided, characterized in that it includes the aforementioned side door drive 100.

[0078] In the description of this specification, the references to terms such as "one embodiment / mode," "some embodiments / modes," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment / mode or example is included in at least one embodiment / mode or example of this application.
