Detailed Description
The present disclosure will be described in further detail with reference to the drawings and embodiments. It is to be understood that the specific embodiments described herein are for purposes of illustration only and are not to be construed as limitations of the present disclosure. It should be further noted that, for the convenience of description, only the portions relevant to the present disclosure are shown in the drawings.
It should be noted that the embodiments and features of the embodiments in the present disclosure may be combined with each other without conflict. Technical solutions of the present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
Unless otherwise indicated, the illustrated exemplary embodiments/examples are to be understood as providing exemplary features of various details of some ways in which the technical concepts of the present disclosure may be practiced. Accordingly, unless otherwise indicated, features of the various embodiments may be additionally combined, separated, interchanged, and/or rearranged without departing from the technical concept of the present disclosure.
The use of cross-hatching and/or shading in the drawings is generally used to clarify the boundaries between adjacent components. As such, unless otherwise noted, the presence or absence of cross-hatching or shading does not convey or indicate any preference or requirement for a particular material, material property, size, proportion, commonality between the illustrated components and/or any other characteristic, attribute, property, etc., of a component. Further, in the drawings, the size and relative sizes of components may be exaggerated for clarity and/or descriptive purposes. While example embodiments may be practiced differently, the specific process sequence may be performed in a different order than that described. For example, two processes described consecutively may be performed substantially simultaneously or in reverse order to that described. In addition, like reference numerals denote like parts.
When an element is referred to as being "on" or "on," "connected to" or "coupled to" another element, it can be directly on, connected or coupled to the other element or intervening elements may be present. However, when an element is referred to as being "directly on," "directly connected to" or "directly coupled to" another element, there are no intervening elements present. For purposes of this disclosure, the term "connected" may refer to physically, electrically, etc., and may or may not have intermediate components.
For descriptive purposes, the present disclosure may use spatially relative terms such as "below … …," below … …, "" below … …, "" below, "" above … …, "" above, "" … …, "" higher, "and" side (e.g., as in "side wall") to describe one component's relationship to another (other) component as illustrated in the figures. Spatially relative terms are intended to encompass different orientations of the device in use, operation, and/or manufacture in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" or "beneath" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "below … …" can encompass both an orientation of "above" and "below". Further, the devices may be otherwise positioned (e.g., rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
The terminology used herein is for the purpose of describing particular embodiments and is not intended to be limiting. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. Furthermore, when the terms "comprises" and/or "comprising" and variations thereof are used in this specification, the presence of stated features, integers, steps, operations, elements, components and/or groups thereof are stated but does not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components and/or groups thereof. It is also noted that, as used herein, the terms "substantially," "about," and other similar terms are used as approximate terms and not as degree terms, and as such, are used to interpret inherent deviations in measured values, calculated values, and/or provided values that would be recognized by one of ordinary skill in the art.
FIG. 3 is a schematic structural view of the motorized door drive mechanism of the present disclosure; fig. 4 is a top view of fig. 3.
An electric door driving mechanism as shown in fig. 3 and 4, in particular, an electric door driving mechanism for an automobile, includes: a drive unit 1, the drive unit 1 generating a driving force; the screw rod 2 is driven by the driving unit 1; the screw nut 3 is matched with the screw rod 2, and when the screw rod 2 rotates, the screw nut 3 is driven to move along the length direction of the screw rod 2; and one end of the ejection mechanism 4 is rotatably connected to the vehicle door, and the other end of the ejection mechanism 4 is rotatably connected to the nut 3, so that when the driving unit 1 drives the screw rod 2 to rotate, the screw rod 2 drives the nut 3 to move, and the nut 3 drives the ejection mechanism 4 to move, so that the vehicle door is opened or closed.
Thus, when the electric vehicle door driving mechanism of the present disclosure is used, the door switch is not directly driven by the screw rod 2, but the opening and closing of the vehicle door is realized by the screw nut 3 and the ejection mechanism 4 moving along the screw rod 2, and therefore, the axial position of the screw rod 2 can be limited, and thus the area of the screw rod envelope is reduced, so that the electric vehicle door driving mechanism of the present disclosure can be conveniently arranged in most vehicle models.
As one implementation form, the other end of the ejection mechanism 4 is rotatably connected to a vehicle-body-side bracket 5, and the vehicle-body-side bracket 5 is fixed to the vehicle door so as to enable the vehicle door to rotate when the ejection mechanism 4 drives the vehicle-body-side bracket 5 to move.
Preferably, the drive unit 1 is an electric motor, such as a dc motor, so that the electric vehicle door drive mechanism of the present disclosure facilitates the control of the drive unit by the VCU after being integrated into the vehicle.
In the present disclosure, the driving unit 1 drives the screw rod 2 to rotate through the speed reducing mechanism 6, so that the moment for driving the opening and closing of the vehicle door is increased, the angular speed of the vehicle door during rotation is low, and the vehicle door is more stable during the opening and closing process.
Fig. 5 is a schematic view of a usage state of the electric door driving mechanism of the present disclosure.
In the present disclosure, referring to fig. 5, the electric vehicle door driving mechanism further includes an execution unit housing 7, and one end of the execution unit housing 7 is fixed to the speed reduction mechanism 6; for example, one end of the actuator case 7 is fixed to the case of the reduction mechanism 6; and the screw rod 2 and a part of the ejection mechanism 4 are positioned in the execution unit shell 7, so that the screw rod 2 and the ejection mechanism 4 are protected by the execution unit shell 7.
On the other hand, both ends of the screw 2 are rotatably supported in bearing seats, and as one implementation form, a bearing seat near the speed reducing mechanism 6 may be fixed to the speed reducing mechanism 6, and the other bearing seat may be fixed to the actuator housing 7; that is, two ends of the screw rod 2 are respectively fixed to the speed reducing mechanism 6 and the execution unit housing 7 through bearing seats, and the position of the screw rod is limited through the bearing seats, so that the screw rod 2 can only rotate.
Of course, one of the bearing seats may be fixed to the housing of the reduction mechanism 6 as long as the position of the lead screw 2 can be fixed.
The ejector mechanism 4 and the vehicle door are rotatably connected by a first connecting shaft 8, and more specifically, the ejector mechanism 5 and the vehicle-body-side bracket 5 are rotatably connected by a first connecting shaft 8, thereby achieving rotatable connection between the ejector mechanism 4 and the vehicle door.
The ejection mechanism 4 is rotatably connected with the nut 3 through a second connecting shaft 9, and the first connecting shaft 8 and the second connecting shaft 9 are arranged in parallel, so that when the nut 3 moves along the axial direction of the screw rod 2, the ejection mechanism 4 can be driven to move, the bracket 5 on the side of the vehicle body can be further driven to move, and the vehicle door can be opened or closed.
Fig. 6 is an exploded view of the motorized door drive mechanism of the present disclosure.
Referring to fig. 4 and 6, the electric vehicle door driving mechanism further includes a blocking piece 10, and the blocking piece 10 is fixed to the second connecting shaft 9 to limit the axial movement of the other end of the ejection mechanism 4 along the second connecting shaft 9, so as to prevent the other end of the ejection mechanism 4 from being separated from the second connecting shaft 9.
As an implementation form, the first connecting shaft 8 is a pin shaft, and the second connecting shaft 9 is a cylinder extending from the nut 3 in a direction perpendicular to the axis of the nut 3.
In the present disclosure, the other end of the ejection mechanism 4 is disposed in the execution unit housing 7, the speed reduction mechanism 6 is formed with a through hole, and one end of the ejection mechanism 4 passes through the through hole and is hinged to the vehicle body side bracket 5.
Fig. 7 is a schematic structural view of another embodiment of the electric vehicle door driving mechanism of the present disclosure.
On the other hand, referring to fig. 7, the speed reduction mechanism 6 is not provided with a through hole, and a part of the ejector mechanism 4 is located outside the speed reduction mechanism 6.
Therefore, in the electric vehicle door driving mechanism, after the execution mechanism is split into the screw rod 2 and the ejection mechanism 4, the ejection mechanism 4 can optimize the shape of the ejection mechanism according to the rotation motion of the vehicle door by using the development mode of the limiting arm of the traditional stopper as reference, and obtain the special-shaped ejection mechanism, so that the motion envelope is reduced, and the electric vehicle door driving mechanism disclosed by the disclosure is easier to arrange in the vehicle door.
According to another aspect of the present disclosure, a vehicle door is provided that includes the above-described power door drive mechanism.
According to another aspect of the present disclosure, a vehicle is provided, which includes the above-described power door drive mechanism or the above-described door.
In the description herein, reference to the description of the terms "one embodiment/mode," "some embodiments/modes," "example," "specific example," or "some examples," etc., means that a particular feature, structure, material, or characteristic described in connection with the embodiment/mode or example is included in at least one embodiment/mode or example of the application. In this specification, the schematic representations of the terms used above are not necessarily intended to be the same embodiment/mode or example. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments/modes or examples.
