Description

Technical Field

[0001] The utility model relates to the technical field of vehicle door equipment, in particular to a track guiding device for a vehicle side swing door. Background Art

[0002] At present, vehicles on the market have doors that swing open sideways. The side-swinging doors have two upper and lower rotating arms. The upper rotating arm is usually connected to a driving device to serve as an active force arm to drive the door to swing sideways, while the lower rotating arm is a slave and performs an auxiliary guiding function. Both rotating arms have a rotating connection point with respect to the door and the body. The length of the lower rotating arm can change with the movement of the door, thereby adjusting the door trajectory in real time, so that the door can swing open sideways and fit against the rear side of the vehicle in the open state. At this time, the two rotating arms are extended backwards to completely release the door opening.

[0003] Among them, since the upper rotating arm connected to the driving device directly connects the car door and the car body through the rotating positions at both ends, the car door needs to be disengaged in a tilted posture during the opening trajectory, otherwise interference is inevitable. Then the car door is driven to perform the opening action through the trajectory formed by the two rotating arms. In this process, a coil spring needs to be applied to apply force. The coil spring is connected to the protruding part of one of the ends of the lower rotating arm to maintain the stability of the door in the opening and closing trajectory. However, the coil spring becomes unstable after long-term use, causing the movement trajectory of the car door to be misaligned, affecting the smoothness of the overall movement. At the same time, due to the movement trajectory of the protruding part, the internal space of the car door is occupied to a certain extent. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model aims to provide a track guide device for a vehicle side swing door.

[0005] The above technical objectives of the utility model are achieved through the following technical solutions: A track guide device for a vehicle side swing door, comprising a swing arm assembly rotatably connecting the vehicle door and the vehicle body, and a guide assembly arranged between the swing arm assembly and the vehicle door;

[0006] The arm assembly comprises an active arm connected to the opening and closing driving force, a driven arm and an adjusting arm that moves with the active arm, one end of the adjusting arm is rotatably connected to the door side end of the driven arm, the other end of the adjusting arm and the door form a door side rotating end, and the other end of the driven arm is rotatably arranged on the vehicle body and forms a vehicle body rotating end;

[0007] The guide assembly includes a track seat fixed on the vehicle door, and a telescopic rod rotatably arranged between the vehicle door and the driven rotating arm, the door side rotating end is arranged on the track seat, and the telescopic rod is arranged on one side of the driven rotating arm close to the door side end, and applies auxiliary force to the vehicle door when opening the track and buffering force when closing the track.

[0008] Furthermore, the active rotating arm and the driven rotating arm are staggered with respect to the front-rear direction of the vehicle body.

[0009] Furthermore, the telescopic rod is stretched in a linear posture along the opening trajectory of the vehicle door, and is compressed along the closing trajectory of the vehicle door.

[0010] Furthermore, the telescopic rod refers to a gas spring or an electric strut.

[0011] Furthermore, the track seat is provided with a track groove, and the driven rotating arm is provided with a sliding part close to the door-side rotating end, and the sliding part is inserted into the track groove to slide.

[0012] Furthermore, the vehicle door has a front closing end corresponding to the door side rotating end, and a rear closing end corresponding to the vehicle body rotating end. In the initial section of the opening trajectory, the trajectory seat and the telescopic rod constrain the rotating arm assembly and force the front closing end to unfold later than the rear closing end. In the terminal section of the closing trajectory, the front closing end is connected to the vehicle body before the rear closing end.

[0013] Furthermore, the distance between the door-side rotating end and the vehicle body rotating end varies with the opening and closing trajectory of the vehicle door.

[0014] Furthermore, a driving unit for providing driving force is disposed on the vehicle body, and the driving unit is connected to the vehicle body end of the active swing arm and provides torque.

[0015] Furthermore, the door of the active rotating arm is arranged at the armrest position of the door and close to the center of the door, and the body end of the active rotating arm is arranged above the wheel hub of the body and below the C-pillar of the body;

[0016] The door end of the driven rotating arm is arranged at the lower part of the door, and the body end of the driven rotating arm is arranged at the stop of the C-pillar of the body, or arranged between the body wheel hub and the body door sill.

[0017] Furthermore, a limit seat is provided on the track seat, and an abutment portion is provided on the adjustment arm. When the front closing end of the door is ready to leave the vehicle body, the abutment portion is pulled by the telescopic rod to rotate, and abuts against the limit seat after the front closing end leaves the door, so as to keep the door open in an unfolded posture;

[0018] The abutment portion rotates under the traction of the telescopic rod when the front closing end of the vehicle door is ready to be engaged with the vehicle body, and moves away from the limit seat as the front closing end is about to be engaged with the vehicle door to release the vehicle door, and the vehicle door forces the front closing end to tilt toward the vehicle door side under the constraint of the telescopic rod.

[0020] Due to the damping force of the telescopic rod itself, the stability of the opening and closing trajectory is improved, so that the opening and closing trajectory of the door and the posture of the opening and closing trajectory are reliably constrained. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0049] It should be understood that although the terms upper, middle, lower, top, end, etc. appear in this article to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish elements from each other for easy understanding, and are not used to define any direction or order limitation.

[0050] like Figure 1-18 As shown, a track guide device for a vehicle side swing door comprises a swing arm assembly 3 rotatably connecting a vehicle door 1 and a vehicle body 2, and a guide assembly arranged between the swing arm assembly 3 and the vehicle door 1;

[0051] The arm assembly 3 comprises an active arm 3.1 connected to the opening and closing driving force, a driven arm 3.2 moving with the active arm 3.1 and an adjusting arm 5.4, one end of the adjusting arm 5.4 is rotatably connected to the door side end of the driven arm 3.2, the other end of the adjusting arm 5.4 is rotatably connected to the vehicle door 1 and constitutes a door side rotating end a, and the other end of the driven arm 3.2 is rotatably arranged on the vehicle body 2 and constitutes a vehicle body rotating end b;

[0052] The guide assembly includes a track seat 5.1 fixed on the vehicle door 1, and a telescopic rod 5.5 rotatably arranged between the vehicle door 1 and the driven rotating arm 3.2, the door side rotating end is arranged on the track seat 5.1, the telescopic rod 5.5 is arranged on one side of the driven rotating arm 3.2 close to the door side end, and the other end of the telescopic rod 5.5 is arranged on one side of the vehicle door 1 close to the active rotating arm 3.1.

[0053] Among them, the guide component exerts a restraining force on the front closed end 1.1 of the door, limits the trajectory of the door side end of the driven rotating arm 3.2, and at the same time gives the driven rotating arm 3.2 an auxiliary force to slide at the starting point of the specified trajectory, and keeps the rear closed end 1.2 of the door in a posture tilted outward in the vehicle width direction to perform an opening action ready to open, or a closing action about to close, and in the above-mentioned opening and closing actions, it is located between the door 1 and the body 2 ready to separate from each other, and the front closed end 1.1 of the door is still close to the front side of the opening of the body 2.

[0054] As a further explanation of the telescopic rod 5.5, the telescopic rod 5.5 applies an auxiliary force to the vehicle door 1 when it is in the opening trajectory, and a buffering force when it is in the closing trajectory, which is beneficial to the smoothness of the switching of the vehicle door 1 from the lifting action to the unfolding action.

[0055] Preferably, the telescopic rod 5.5 is arranged at the same height as the driven rotating arm 3.2, and the rotational connection position between the telescopic rod 5.5 and the driven rotating arm 3.2 is located on the side of the driven rotating arm 3.2 facing the vehicle door 1.

[0056] Specifically, the telescopic rod 5.5 is stretched in a linear posture along the opening trajectory of the vehicle door 1 and is compressed along the closing trajectory of the vehicle door 1, and the telescopic rod 5.5 has a tendency to stretch in a compressed state.

[0057] Specifically, the telescopic rod 5.5 refers to a piston or a gas spring or an electric strut.

[0058] like Figure 5 and Figure 6 As shown, in other embodiments, in order to restrict the rotation of the telescopic rod 5.5, a fixing seat 7 is further provided on the vehicle door 1, and the fixing seat 7 is arranged between the driven rotating arm 3.2 and the active rotating arm 3.1, and the telescopic rod 5.5 is passed through the fixing seat 7, and a groove 7.1 is provided on the fixing seat 7 for the telescopic rod 5.5 to slide relatively with the opening and closing of the vehicle door 1, and the groove 7.1 is arranged along the vehicle width direction, so that the vertical movement of the telescopic rod 5.5 is limited by the groove 7.1, and at the same time, it is ensured that the telescopic rod 5.5 rotates within a predetermined deployment area, thereby avoiding excessive rotation of the telescopic rod 5.5 in an emergency.

[0059] Further references Figure 7 As a further implementation of the track seat 5.1, a track groove is provided on the track seat 5.1, and a sliding portion 3.21 close to the door side rotating end is provided on the driven swing arm 3.2. The sliding portion 3.21 is inserted into the track groove and slides. During the opening process, the telescopic rod and the track seat swing along with the rotation of the car door and the driven swing arm, and are arranged toward the track groove on the track seat.

[0060] Specifically, the track seat 5.1 forms a cavity in the up-down direction of the door 1, and a transmission arm 3.22 extends from the vehicle body 2 of the driven rotating arm 3.2, and the transmission arm 3.22 is placed in the track seat 5.1, and the sliding part 3.21 is arranged on the transmission arm 3.22 and is slidably connected with the track seat 5.1 in the up-down direction of the door 1.

[0061] Among them, on the transmission arm, the rotating end of the telescopic rod 5.5, the sliding part 3.21, and the rotating connection end with the adjustment arm 5.4 are sequentially extended toward the end of the transmission arm 3.22, and the rotating end of the telescopic rod 5.5 is arranged outside the track seat 5.1.

[0062] Specifically, the door 1 has a front door closing end 1.1 corresponding to the door side rotating end, and has a rear door closing end 1.2 corresponding to the vehicle body 2 rotating end. In the initial section of the opening trajectory, the trajectory seat 5.1 and the telescopic rod 5.5 constrain the rotating arm assembly 3 and force the front closing end to be delayed in unfolding before the rear closing end. In the terminal section of the closing trajectory, the front closing end is connected to the vehicle body 2 before the rear closing end, that is, Figures 2 to 3 ,as well as Figures 9 and 10 The door 1 action.

[0063] Specifically, the distance between the door-side rotating end a and the vehicle body rotating end b changes with the opening and closing trajectory of the door 1, wherein the distance gradually decreases in the trajectory of the door 1 from the fully closed state to the tilting trajectory of the door 1 ready to be opened, and gradually increases in the trajectory of further unfolding to the fully open position.

[0064] During the process of reducing the spacing, the front closing end of the door 1 is pulled by the guide assembly and is closer to the vehicle body 2 than the rear closing end of the door 1, so that the door 1 forms an inclined posture, so that the front closing end of the door 1 can be disengaged from the interference position under the drive of the active swing arm 3.1.

[0065] Reference Figure 7 and Fig.10 As shown, as a further implementation of the track seat 5.1, a track groove is provided on the track seat 5.1, and the track groove has a raised section 5.2 corresponding to the preparation for opening action and the upcoming closing action, and a U-shaped section 5.3 corresponding to the door 1 from preparation for opening to full opening and from full opening to closing. The raised section 5.2 and the U-shaped section 5.3 are both arranged in an arc shape, and the U-shaped section 5.3 has a tendency to bend toward the inner side of the vehicle width. The raised section 5.2 extends outside the vehicle width along the end of the U-shaped section 5.3, and the raised section 5.2 corresponds to the initial section of the opening track.

[0066] Among them, the connecting part of the adjusting arm 5.4 on the track seat 5.1 serves as the door-side rotating end a of the adjusting arm 5.4. The distance between the door-side rotating end a and the vehicle body rotating end b can be more intuitively reflected through the distance between the sliding part 3.21 and the door-side rotating end a. The distance between the sliding part 3.21 and the door-side rotating end a of the adjusting arm 5.4 is adjusted by sliding the sliding part 3.21 in the track seat 5.1.

[0067] In the opening action of the door 1 preparing to open, the driven rotating arm 3.2 rotates under the traction of the door 1 and the telescopic rod 5.5, and actuates the adjusting arm 5.4 to rotate. The door-side rotating end of the adjusting arm 5.4 at least approaches the sliding portion 3.21 since the opening action, so that the distance between the sliding portion 3.21 and the door-side rotating end of the adjusting arm 5.4 is reduced, and the telescopic rod 5.5 exerts a force on the driven rotating arm 3.2 to actuate the adjusting arm 5.4 and the driven rotating arm 3.2 to continue rotating. At this time, the distance between the door-side rotating end of the adjusting arm 5.4 and the sliding portion 3.21 is reduced, and the front closed end 1.1 of the door is guided by the lifting section 5.2. The lower door 1 is unfolded with a delay later than the rear closed end 1.2 of the door, so that the front closed end of the door 1 moves in an inclined posture, thereby avoiding the interference of the vehicle body 2 and the door 1 on the other side. Then the door 1 is continued to be driven to rotate by the active rotating arm 3.1, and the adjusting arm 5.4 rotates and stops to the extreme position of the track seat 5.1, so that the front closed end of the door 1 can be unfolded and unfolded and approached to a position flush with the rear closed end 1.2 of the door in an arc-shaped track in the vehicle width direction. At this time, the sliding part 3.21 slides in the U-shaped section 5.3, and the distance between the sliding part 3.21 and the door-side rotating end of the adjusting arm 5.4 gradually lengthens.

[0068] The warping section 5.2 has an arc-shaped sliding groove 5.21, and a starting point 5.22 and a transition point 5.23 which are arc-shapedly connected at both ends of the sliding groove 5.21, wherein the starting point 5.22 is far away from the U-shaped section 5.3, and the transition point 5.23 is connected to the U-shaped section 5.3, and the centers of the starting point 5.22, the sliding groove 5.21 and the transition point 5.23 are staggered in sequence in the vehicle width direction, and the door-side rotating end of the adjusting arm 5.4 on the track seat 5.1 is located on the vehicle width outside of the transition point 5.23, and the door-side rotating end is arranged adjacent to the U-shaped section and the transition point 5.23.

[0069] As an example, the center of the starting point 5.22 is located outside the track groove in the vehicle width direction, the center of the sliding groove 5.21 is located inside the track groove in the vehicle width direction, and the center of the transition point 5.23 is located outside the track groove in the vehicle width direction.

[0070] Among them, the starting point 5.22 has a locking effect on the closed position of the sliding part 3.21, which is beneficial to improve the stability of the vehicle door 1 in the closed position and reduce shaking; when the sliding part 3.21 moves to the transition point 5.23, the vehicle door 1 enters an inclined detachable state. In addition, the transition point 5.23, while connecting the raised section 5.2 and the U-shaped section 5.3, is beneficial to guiding the front closed end of the vehicle door 1 to a position where it can be quickly unfolded.

[0071] It is worth mentioning that, in the opening trajectory, the telescopic rod 5.5 provides auxiliary force for the sliding part 3.21 to switch from the lifting section 5.2 to the U-shaped section 5.3, which is smoother.

[0072] Combination Figure 1 and Figure 4 In this embodiment, the door 1 end of the active rotating arm 3.1 is arranged at the armrest position of the door 1 and close to the center of the door 1, and the body 2 end of the active rotating arm 3.1 is arranged above the wheel hub of the body 2 and below the C-pillar of the body 2;

[0073] The door 1 end of the driven rotating arm 3.2 is arranged at the lower part of the door 1, and the body 2 end of the driven rotating arm 3.2 is arranged at the stop of the C-pillar of the body 2, or arranged between the wheel hub of the body 2 and the door sill of the body 2.

[0074] like Figure 7 and Fig.10 As shown, specifically, a limit seat 5.11 is further provided on the track seat 5.1, and an abutment portion 5.41 is provided on the adjustment arm 5.4. The abutment portion 5.41 is pulled by the telescopic rod 5.5 to rotate when the front closing end of the door 1 is ready to leave the vehicle body 2, and abuts against the limit seat 5.11 after the front closing end leaves the door 1, so as to keep the door 1 open in an unfolded posture;

[0075] When the front closing end of the vehicle door 1 is ready to be engaged to the vehicle body 2, the abutment portion 5.41 moves away from the limiting seat 5.11 as the front closing end is about to be engaged to the vehicle door 1 to release the vehicle door 1, and the vehicle door 1 is forced to tilt the front closing end toward the side of the vehicle door 1 under the constraint of the telescopic rod 5.5, so that the front closing end of the vehicle door 1 can be re-engaged to the fully closed position.

[0076] The limiting seat 5.11 includes a first limiting portion 5.12 extending in the vehicle width direction and a second limiting portion 5.13 extending in the vehicle length direction. In the unfolding action after the opening preparation is completed, the abutting portion 5.41 is stopped by the first limiting portion 5.12 and the second limiting portion 5.13, which is beneficial to limiting the displacement of the sliding portion 3.21 in the track groove.

[0077] In the utility model, a telescopic rod 5.5 is connected between the vehicle body 2 and the driven rotating arm 3.2, and the door side end of the driven rotating arm 3.2 is connected to the track seat 5.1 of the vehicle door 1 through a rotating adjusting arm 5.4, so that when the vehicle door 1 opens the track, the active rotating arm 3.1 actuates the rear end of the vehicle door 1 to rotate and unfold, and in the initial section of the opening track, the distance between the door side rotating end and the driving end of the vehicle body 2 is compressed due to the rotation of the adjusting arm 5.4, so that the vehicle door 1 is pulled away from the front closed end of the body with its rear end raised, and then the front closed end of the vehicle door 1 is unfolded under the traction of the track groove and the telescopic rod 5.5, and the opening of the vehicle body 2 is completely released.

[0078] like Figure 4 and Fig.14 As shown, specifically, a driving unit 6 for providing driving force is provided on the vehicle body 2, and the driving unit 6 is connected to the vehicle body 2 end of the active swing arm 3.1 and provides torque.

[0079] In this embodiment, the swing arm assembly 3 is arranged on one side of the interior trim panel of the vehicle door 1, and the swing arm assembly 3 includes an active swing arm 3.1 and a driven swing arm 3.2. One end of the active swing arm 3.1 is connected to the driving unit 6 and is rotatably arranged on the vehicle body 2, and the other end of the active swing arm 3.1 is rotatably connected to and actuates the vehicle door 1. The driving unit 6 is used to provide a rotation torque of the active swing arm 3.1 to drive the vehicle door 1 and pull the driven swing arm 3.2 to move;

[0080] One end of the driven rotating arm 3.2 is rotatably arranged on the vehicle body 2, and the door side end of the driven rotating arm 3.2 is rotatably connected to the guide assembly, and the distance between the door side end of the driven rotating arm 3.2 and the vehicle door 1 is rotatably connected in an adjustable manner, and the distance changes with the rotation of the active rotating arm 3.1 and through the guide assembly. The guide assembly is specifically arranged between the door side rotating end of the driven rotating arm 3.2 and the vehicle door 1.

[0081] 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, they are bent from the vehicle body 2 toward the vehicle door 1 side, and when the vehicle door 1 is in a fully closed position,

[0082] The rotating connecting ends of the active rotating arm 3.1 and the driven rotating arm 3.2 on the vehicle door 1 and the vehicle body 2 are staggered front and rearward with respect to the direction of the vehicle body 2. The door-side rotating ends of the driven rotating arm 3.2 and the adjusting arm 5.4 are arranged closer to the front closing end 1.1 of the vehicle door than the door 1 rotating end of the active rotating arm 3.1, so that the door-side rotating end of the driven rotating arm 3.2 can cooperate with the guide component on the front closing end 1.1 of the vehicle door to limit the posture of the front closing end 1.1 of the vehicle door during the action of preparing to open the vehicle door 1 and about to fully close the vehicle door 1, that is, to constrain the vehicle door 1 from extending its rear closing end outward in the vehicle width direction compared with the front closing end.

[0083] The active swing arm 3.1 and the driven swing arm 3.2 are staggered with respect to the front-rear direction of the vehicle body 2.

[0084] As an example, the door-side rotating end of the active rotating arm 3.1 is located behind the door-side rotating end of the driven rotating arm 3.2, the body rotating end b of the driven rotating arm 3.2 is located behind the door-side rotating end of the active rotating arm 3.1, and the body rotating end b of the active rotating arm 3.1 is located behind the body rotating end b of the driven rotating arm 3.2.

[0085] like Fig.12 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 swing end b, and the door-side swing end of the active swing arm 3.1 moves to the rear side of its vehicle body swing end b 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 swing end b 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;

[0086] like Fig.11 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.

[0087] 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.

[0088] 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.

[0089] Thus, the vehicle door 1 is opened and closed by the quadrilateral link structure formed by the above-mentioned rotating arm assembly 3 .

[0090] In the above embodiment, a protective shell 3.11 is provided on the outer side of the active rotating arm 3.1. When the vehicle door 1 is opened, the passengers can use the protective shell 3.11 as a handrail to facilitate getting on and off the vehicle.
