Description

Technical Field

[0001] The utility model relates to the technical field of vehicle door equipment, and particularly relates to an opening and closing guiding device for a vehicle side-swing door. Background Art

[0002] At present, among vehicles on the market, there are side-swing doors. The side-swing door has two upper and lower swing arms. Usually, the upper swing arm is connected to a driving device to serve as the main power arm to drive the door to perform a side-swing action. The lower swing arm moves passively and performs an auxiliary guiding function. Both swing arms have rotational connection points with respect to the door and the vehicle body. Among them, the length of the lower swing arm can change with the movement of the door, thereby adjusting the door trajectory in real time, enabling the door to swing open and fit against the rear side of the vehicle in the open state. At this time, the two swing arms unfold backward to completely release the door opening.

[0003] However, since the driving position of the swing arm is set at the rear side of the vehicle opening, at the initial stage of opening and the end stage of closing of this kind of door, the front closing end of the door is far from the driving device and is prone to jitter, which may lead to unreliable actions at the initial stage of opening and the end stage of closing of the door, and even unable to close completely, resulting in the door not being able to be fully locked or the smoothness in the above action stages. Summary of the Utility Model

[0012] Furthermore, the guide channel and the guide block extend at least in the length direction of the vehicle body, and the guide channel is provided with an entrance section expanding in the vehicle width direction at an opening allowing the guide block to enter.

[0013] Furthermore, the guide block is provided with guide mating surfaces on the inner and outer sides of the vehicle body, the guide mating surfaces are connected at the end of the guide block and form a guide protrusion, the guide protrusion abuts against the end of the arc surface of the outer guide part and is restricted from moving outward in the vehicle width direction.

[0014] Furthermore, the inner guide portion is in the form of an arc convex portion facing the inner surface of the guide block, and is supported on a side of the guide block close to the vehicle body when the door is in a closed position.

[0015] Furthermore, the outer guide portion includes a first guide segment and a second guide segment which are sequentially arranged in the door opening direction, the first guide segment receives and fits the end of the guide block, and a guide joint portion is provided at the end of the first guide segment.

[0016] Furthermore, an outer surface of one or more of the guide block, the outer guide portion and the inner guide portion is provided with a sheath.

[0017] Furthermore, the inner guide portion includes a rotating shaft, and when the door is about to be opened or closed, the rotating shaft rotates as the guide block is touched.

[0018] Furthermore, the guide block includes an arc-shaped main body and a first sleeve arranged on the arc-shaped main body.

[0019] Furthermore, the inner guide portion includes a rotating shaft and a second sleeve arranged outside the rotating shaft.

[0020] Furthermore, the guide assembly also includes a base, the outer guide portion and / or the inner guide portion is arranged on the base, and the base is arranged on the closed end of the vehicle body and is adjustable with respect to the front-rear direction of the vehicle door.

[0045] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0046] It should be understood that although terms such as upper, middle, lower, top, one end, etc. appear in this text to describe various components, these components are not limited by these terms. These terms are only used to distinguish components from each other for ease of understanding, rather than to define any directional or sequential limitations.

[0047] As Figures 1-14 shown, an opening and closing guiding device for a vehicle swing door includes a swing arm assembly 3 that rotatably connects a door 1 and a vehicle body 2. The door 1 opens and closes relative to the vehicle body 2 through the action of the swing arm assembly 3; between the door 1 and the vehicle body 2, there are a door closing end of the door 1, a vehicle body closing end, and a guiding assembly 4 that cooperate during opening and closing, and there is also a trajectory guiding assembly 5 for restricting the movement trajectory of the door closing end of the door 1 between the door 1 and the vehicle body 2. Among them, the guiding assembly 4 is arranged at the front closing end 1.1 of the door. As a deformation of the present invention, the guiding assembly 4 can also be arranged at the rear closing end 1.2 of the door;

[0048] Combined with Figure 2 and Figures 11 to 14 shown, among them, the swing arm assembly 3 is arranged on one side of the interior trim panel of the door 1. The swing arm assembly 3 includes a driving swing arm 3.1 and a driven swing arm 3.2. One end of the driving swing arm 3.1 is connected to a driving unit 6 and rotatably arranged on the vehicle body 2. The other end of the driving swing arm 3.1 is rotatably connected to and actuates the door 1. The driving unit 6 is used to provide the rotational torque of the driving swing arm 3.1 to drive the door 1 and drive the driven swing arm 3.2 to move;

[0049] One end of the driven swing arm 3.2 is rotatably arranged on the vehicle body 2. The door-side end of the driven swing arm 3.2 is rotatably connected to the trajectory guiding assembly 5, and the distance between the door-side end of the driven swing arm 3.2 and the door 1 is rotatably connected through a link structure and can be adjusted. This distance changes with the rotation of the driving swing arm 3.1 and through the trajectory guiding assembly 5. The trajectory guiding assembly 5 is specifically arranged between the door-side rotating end of the driven swing arm 3.2 and the door 1.

[0050] As Figure 3 and Figure 4 shown, as a further implementation of the guiding assembly 4, the guiding assembly 4 cooperates with each other in the fully closed state of the door 1 to limit the position between the door closing end of the door 1 and the vehicle body closing end, ensuring the stability of the door 1 in the closed state, and the other end far from the door 1 is held by the driving unit 6.

[0051] The guiding assembly 4 includes a guiding seat 4.1 arranged on one of the door closing end of the door 1 and the vehicle body closing end, and a guiding block 4.2 arranged on the other of the door closing end of the door 1 and the vehicle body closing end;

[0052] When the door 1 swings, the guide seat 4.1 and the guide block 4.2 cooperate with each other and tilt to an obstacle-free posture as the door swings. Subsequently, the active swing arm 3.1 continues to move to drive the door, causing the guide block 4.2 to disengage from the guide seat 4.1. In addition, when the door is about to close, the guide seat 4.1 and the guide block 4.2 engage with each other and gradually abut against each other in the vehicle width direction and the closing direction of the vehicle body 2 as the door 1 swings.

[0053] The guide seat 4.1 includes an outer guide portion 4.3 and an inner guide portion 4.4 that are spaced apart in the front-rear direction of the vehicle body 2. There are oppositely arranged arc surfaces 4.5 between the outer guide portion 4.3 and the inner guide portion 4.4 for the guide block 4.2 to abut and cooperate with at least one arc surface 4.5 when the door 1 performs opening and closing actions.

[0054] The arc surfaces 4.5 are spaced apart in the vehicle width direction of the vehicle body 2 and limit the lateral movement of the guide block 4.2 in the vehicle width direction when the door 1 is in the closed position.

[0055] As Figures 12 to 14 shown, as a further implementation of the track guiding assembly 5, the track guiding assembly 5 exerts a binding force on the front closing end 1.1 of the door to limit the trajectory of the door-side rotating end of the driven swing arm 3.2, thereby controlling the trajectory of the front closing end 1.1 of the door. At the same time, an auxiliary acting force for the driven swing arm 3.2 to slide at the starting point of the defined trajectory is given by the gas spring 5.5, and the rear closing end of the door 1 is maintained in a posture tilted outward in the vehicle width direction to perform the opening action of preparing to open or the closing action of about to close. During the above opening and closing actions, the guiding assembly 4 between the door 1 and the vehicle body 2 is prepared to disengage from each other, and the front closing end 1.1 of the door is still close to the front side of the opening of the vehicle body 2.

[0056] Specifically, the track guiding assembly 5 includes a track seat 5.1 disposed near the front closing end of the door 1, and an adjusting arm 5.4 rotatably disposed between the track seat 5.1 and the door-side end of the driven swing arm 3.2. A track groove 5.3 is provided in the track seat 5.1, and the driven swing arm 3.2 has a guide shaft 3.21 rotatably disposed in the track groove 5.3. The track groove 5.3 has a lifting section 5.2 for guiding the movement trajectory of the front closing end of the door 1. The lifting section 5.2 is arranged as an inclined arc section. In this way, the trajectory of the front closing end 1.1 of the door is defined when preparing to open and about to close. During this process, the guiding assembly 4 restricts the front closing end 1.1 of the door to prevent excessive yaw, effectively improving the reliability of the door 1 movement.

[0057] During the actions of the door 1 preparing to open and about to close, the guide block 4.2 is constrained within the guide channel defined by the inner guide portion 4.4 and the outer guide portion 4.3.

[0058] FromFigure 4 As can be seen, specifically, the outer guiding portion 4.3 is provided with an opening facing the guiding block 4.2. The inner guiding portion 4.4 is located in the opening direction of the outer guiding block 4.2. The guiding block 4.2 can enter and leave the guiding channel through this opening. Moreover, during the preparation for opening and closing actions, the guiding block 4.2 can be limited in the vehicle body 2 direction by both the outer guiding portion 4.3 and the inner guiding portion 4.4, thereby improving the reliability of the opening and closing actions of the vehicle door 1.

[0059] Specifically, guiding channels adapted to the contour of the guiding block 4.2 are spaced between the arc-shaped surfaces 4.5. The inner and outer surfaces of the guiding block 4.2 abut against the arc-shaped surfaces 4.5 in the closed position of the vehicle door 1.

[0060] Further in combination with Figures 5 to 7 As shown, specifically, the guiding channel and the guiding block 4.2 extend at least in the vehicle body 2 length direction, and the guiding channel is provided with an inlet section that expands in the vehicle width direction at the opening allowing the guiding block 4.2 to enter. Through the setting of this inlet section, it is beneficial for the guiding block 4.2 to enter or leave the guiding seat 4.1 following the opening and closing actions of the vehicle door 1, while the inner guiding portion 4.4 located at the rear can still... during the upward tilting process of the vehicle door 1.

[0061] Specifically, guiding mating surfaces 4.21 are provided on the inner and outer sides of the guiding block 4.2 with respect to the vehicle body 2. The guiding mating surfaces 4.21 are connected at the end of the guiding block 4.2 and form a guiding convex portion 4.22. The guiding convex portion 4.22 abuts against the end of the arc-shaped surface 4.5 of the outer guiding portion 4.3 and is restricted from moving outward in the vehicle width direction. In the fully closed state, the guiding convex portion 4.22 abuts against the end of the arc-shaped surface 4.5 of the outer guiding portion 4.3, and the guiding block 4.2 is restricted from moving outward by the two arc-shaped surfaces 4.5 in the vehicle width direction. Thus, it effectively avoids the jitter and noise generated by the vehicle door 1 during driving, especially the mating stability between the front closing end 1.1 of the vehicle door and the vehicle body 2.

[0062] As Figure 6 and Figure 7 shown, during the opening action in preparation for opening, the guiding mating surface 4.21 is used to cooperate with the arc-shaped surface 4.5 between the outer guiding portion 4.3 and the inner guiding portion 4.4 to play a certain guiding role. After the preparation for the opening action is completed, the guiding block 4.2 and the guiding seat 4.1 reach a non-obstructed posture in the subsequent opening trajectory of the vehicle door 1 as shown in Figure 8 . At the same time, the front closing end 1.1 of the vehicle door and another vehicle door 1, or the vehicle body 2 reach a non-obstructed posture, allowing the front closing end of the vehicle door 1 to leave the vehicle body 2 opening without interference and further expand to the fully open state.

[0063] In the process of preparing to open, the rear closed end of the door 1 is expanded toward the outside of the vehicle width under the actuation of the active rotating arm 3.1, while the front closed end 1.1 of the door is still swayed in the constraint of the track guide assembly 5, forming a tilted posture of the door 1, so as to disengage from the vehicle body 2 and the front door 1 without obstacles. In this process, the guide block 4.2 still needs to be constrained in the guide channel to ensure the tilted posture of the front closed end 1.1 of the door.

[0064] Specifically, the inner guide portion 4.4 is an arc convex portion facing the inner surface of the guide block 4.2, and is supported on the side of the guide block 4.2 close to the vehicle body 2 when the door 1 is in the closed position, thereby reducing the resistance of sliding friction while ensuring the supporting effect in the vehicle width direction.

[0065] Preferably, the inner guide portion 4.4 is rotatably positioned on the front closed end of the vehicle body 2, thereby further reducing the resistance between the guide block 4.2 and the inner guide portion 4.4.

[0066] Reference Figure 6 As shown, in other embodiments, in order to further optimize the guide assembly 4, the outer surface of one or more of the guide block 4.2, the outer guide portion 4.3 and the inner guide portion 4.4 is provided with a cover, and the cover is preferably made of a wear-resistant and shock-absorbing material, thereby further reducing the contact sound when the vehicle door 1 is about to be opened and about to be closed, and at the same time, effectively increasing the service life of the guide block 4.2 and the guide seat 4.1.

[0067] In addition, the provision of the sleeve is helpful to increase the smoothness of the guide assembly 4 when relative sliding occurs, and reduce the generation of abnormal noise.

[0068] As an arrangement of the guide seat 4.1, the guide assembly 4 also includes a base 4.6, a mounting position corresponding to the base 4.6 is provided on the closed end of the vehicle body 2, the outer guide portion 4.3 and / or the inner guide portion 4.4 are arranged on the base 4.6, and the base 4.6 is arranged on the closed end of the vehicle body 2 and is adjustable with respect to the front and rear directions of the vehicle door 1.

[0069] As an example, the base 4.6 is provided with an adjustment slot 4.61 along the front-rear direction of the vehicle body 2, and the relative position of the guide seat 4.1 and the guide block 4.2 is achieved by adjusting the position of the base 4.6.

[0070] Furthermore, an adjustment groove 4.61 may be provided on the inner guide portion 4.4 and the outer guide portion 4.3 to further adjust the relative position of the inner guide portion 4.4 and the outer guide portion 4.3, and adjust the relative position of the guide seat 4.1 and the guide block 4.2 according to different assembly conditions.

[0071] As an example of the inner guiding part 4.4, the inner guiding part 4.4 includes a base 4.41 and a rotating shaft 4.42 rotatably arranged on the base 4.41. During the actions of the vehicle door 1 preparing to open and about to close, the rotating shaft 4.42 rotates with the touch of the guiding block 4.2.

[0072] Wherein, a second sheath 4.43 is provided outside the rotating shaft 4.42.

[0073] Specifically, the guiding block 4.2 includes an arc-shaped main body 4.36 and a first sheath 4.37 provided on the arc-shaped main body 4.36. And the arc-shaped main body 4.36 is provided with a plurality of holes in its extending direction, and this way is beneficial to reducing abnormal noises.

[0074] Preferably, the arc-shaped main body 4.36 is made of a metal material with a certain strength to ensure the structural reliability of the guiding block 4.2, and the first sheath 4.37 is preferably arranged on the arc-shaped main body 4.36 in a plastic-coated form.

[0075] In this embodiment, in order to adapt to the accompanying warping action of the front closing end 1.1 of the vehicle door, a guiding space 4.31 allowing the guiding block 4.2 to be offset towards the inner rear side of the vehicle body 2 during the opening action is provided at the front end of the outer guiding part 4.3, and a release space 4.32 for allowing the guiding block 4.2 to tilt and disengage from the surface of the inner guiding part 4.4 towards the vehicle width outer direction is provided at the tail end of the outer guiding part 4.3. At this time, the outer guiding mating surface 4.21 of the guiding block 4.2 can slide and be guided on the first guiding section 4.33. At the same time, the guiding block 4.2 slides and is guided with the inner guiding part 4.4 as the vehicle door 1 moves at the rear side of the vehicle body 2 until the guiding mating surface 4.21 of the guiding block 4.2 all leaves the arc-shaped surface 4.5 in the guiding channel, so as to reach a barrier-free posture. Thus, through the yaw of the vehicle door 1 during the action of preparing to open, the guiding block 4.2 rotates in the guiding seat 4.1, and the guiding space 4.31 and the release space 4.32 give the guiding block 4.2 the condition to disengage in a barrier-free posture. Among them, the constraint trajectory of the trajectory guiding assembly 5 for the driven rotating arm 3.2 is arc-shaped, so as to be able to optimize the complete disengagement action of the guiding block 4.2 in the guiding channel on the basis of the arc-shaped guiding block 4.2.

[0076] Preferably, the number of the guiding assemblies 4 is two groups, and the two groups of guiding assemblies 4 are respectively arranged on the upper and lower sides of the closing ends of the vehicle door 1 and the vehicle body 2 to further strengthen the stabilizing and holding effects on the vehicle door 1.

[0077] As a further implementation of the outer guiding part 4.3, the outer guiding part 4.3 includes a first guiding section 4.33 and a second guiding section 4.34 arranged in sequence in the opening direction of the vehicle door 1. The first guiding section 4.33 extends in the direction from the closed end of the vehicle body 2 towards the outside of the vehicle width and has an extension part in the rear side direction of the vehicle body 2, thereby forming a semi-open closed mouth to provide a limit for the vehicle door 1 and the guiding block 4.2 in the front direction of the vehicle body 2. At the same time, the limit for the vehicle door 1 and the guiding block 4.2 in the vehicle width outer direction is ensured by the extension of the first guiding section 4.33, so that the first guiding section 4.33 receives and fits the end of the guiding block 4.2.

[0078] Further, the second guiding section 4.34 expands further towards the outside of the vehicle width at the end of the first guiding section 4.33, so as to form an entrance section together with the inner guiding part 4.4 connected to the front closed end of the vehicle body 2, facilitating the detachment and entry of the guiding block 4.2.

[0079] Further, a guiding joint part 4.35 is provided at the end of the first guiding section 4.33. The guiding joint part 4.35 is arranged between the first guiding section 4.33 and the second guiding section 4.34 and forms a part protruding in the guiding channel. Thus, at the initial stage when the vehicle door 1 is about to start the opening action, the guiding joint part 4.35 can further restrict the guiding block 4.2 and prevent excessive movement of the guiding block 4.2. At the same time, when the guiding block 4.2 moves from the warping trajectory to the position ready to be detached, the guiding joint part 4.35 also plays a role in receiving the guiding block 4.3, thereby restricting the crosstalk of the vehicle door and the guiding block 4.2 during the trajectory switching.

[0080] As a further explanation of the swing arm assembly 3, the active swing arm 3.1 and the driven swing arm 3.2 are in a bent posture, specifically bent from the vehicle body 2 towards the vehicle door 1 side. And in the fully closed position of the vehicle door 1, the rotation connection ends of the active swing arm 3.1 and the driven swing arm 3.2 on the vehicle door 1 and the vehicle body 2 are arranged in a front-back dislocation with respect to the vehicle body 2 direction. The door side rotation end of the driven swing arm 3.2 and the adjusting arm 5.4 is arranged closer to the front closed end 1.1 of the vehicle door than the vehicle door rotation end of the active swing arm 3.1. Thus, through the door side rotation end of the driven swing arm 3.2, it can cooperate with the trajectory guiding assembly 5 on the front closed end 1.1 of the vehicle door to limit the pose of the front closed end 1.1 of the vehicle door during the preparation for opening and the action of about to be fully closed, that is, to restrict the vehicle door 1 in a posture where its rear closed end extends outwards in the vehicle width direction compared with the front closed end.

[0081] As Figure 2 shown, by way of example, the door side rotation end of the active swing arm 3.1 is located behind the door side rotation end of the driven swing arm 3.2, the vehicle body rotation end of the driven swing arm 3.2 is located behind the door side rotation end of the active swing arm 3.1, and the vehicle body rotation end of the active swing arm 3.1 is located behind the vehicle body rotation end of the driven swing arm 3.2.

[0082] like Figure 14 As shown, when the door 1 is fully opened, the door 1 approaches the rear of the opening of the vehicle body 2 in a posture roughly parallel to the vehicle body 2, and the swing arm assembly 3 rotates to the rear side of the opening of the vehicle body 2. At this time, the door-side swing end of the driven swing arm 3.2 moves to the rear side of its vehicle body 2 swing end, and the door-side swing end of the active swing arm 3.1 moves to the rear side of its vehicle body 2 swing end and is located at the rear side of the opening of the vehicle body 2, wherein the door-side swing end of the driven swing arm 3.2 is close to the vehicle body 2 swing end of the active swing arm 3.1, preferably close to or located at the rear side of the opening of the vehicle body 2, so as to release the opening of the vehicle body 2 and facilitate the entry and exit of passengers;

[0083] like Figure 13 As shown, the door 1 also has a maximum outward movement state in the opening trajectory of the door 1, at which time the active rotating arm 3.1 and the driven rotating arm 3.2 are close to being perpendicular to the vehicle body 2.

[0084] When the vehicle door 1 is in a fully closed state, the active rotating arm 3.1 and the driven rotating arm 3.2 are closed together between the opening of the vehicle body 2 and the vehicle door 1, and are substantially parallel to each other.

[0085] It can be understood that the vehicle door 1 being parallel to the vehicle body 2 means being roughly parallel, and the purpose is to reduce the space occupied by the vehicle door 1 outside the vehicle body 2 to avoid interference with the outside world.

[0086] Thus, the vehicle door 1 is opened and closed by the quadrilateral link structure formed by the above-mentioned rotating arm assembly 3 .

[0087] Furthermore, the guide block 4.2 is supported between the inner guide portion 4.4 and the outer guide portion 4.3 when the vehicle door 1 is in the closed position, and in the closed position, there is a movable space in the guide channel to allow the rear end of the guide block 4.2 to be lifted up, and to allow the guide protrusion 4.22 of the guide block 4.2 to swing accordingly, so that the movement of the vehicle door 1 from closing to lifting is limited in the guide channel through the movable space, thereby preventing the vehicle door 1 from excessive movement.

[0088] like Figure 2 and Figure 10 As shown, in the above embodiment, the driving unit 6 refers to the motor 6.1 that provides rotational power, and the reduction box 6.2 connected between the active swing arm 3.1 and the motor 6.1, and the body 2 end of the active swing arm 3.1 is provided with a gear portion 3.12 that is transmission-connected to the reduction box 6.2.

[0089] This specific embodiment is only an interpretation of the present utility model, and it is not a limitation to the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as it is within the scope of the claims of the present utility model, it is protected by the patent law.
