Description

Technical Field

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

[0002] Side swing doors are commonly found in various vehicles, especially passenger cars, buses, MPVs, commercial vehicles, etc. They swing around a vertical axis and rotate along a predetermined moving path through the driving device of the swing door. There are various types of side swing doors, including front and rear side doors that rotate to open, front and rear side doors that slide to open, front door rotation side opening and rear door sliding side opening.

[0003] At present, electric side sliding doors have become standard equipment for high-end models in the market. They are operated by remote control, touch buttons, gesture control and other methods, providing convenient opening methods. Among them, the driving device of the side swing door mainly includes an actuator and a transmission mechanism. The actuator can be a fluid cylinder (such as a pneumatic cylinder, a hydraulic cylinder) or an electric motor. The transmission mechanism transmits the power of the actuator to the swing door, including multiple transmission components. The upper and lower rotating connecting rods are one of the core components of the side swing door. They are located at the upper and lower parts of the door respectively, and are connected to the door and the body through hinges or similar mechanisms. When the door needs to be opened or closed, these connecting rods will rotate around their fixed points, thereby driving the door to swing. The upper connecting rod is usually used to support the upper part of the door to ensure the stability and balance of the door during the swinging process. The lower connecting rod is more responsible for power transmission and guiding when the door is opened and closed.

[0004] However, the automobile side swing door in the prior art still has the risk of collision between the door and the vehicle body or other obstacles of the vehicle body at the initial opening and final closing stages, or there are problems of shaking and noise caused by the unstable closing position of the side swing door during vehicle driving. Therefore, there is a need for a vehicle side swing door that is stable, reliable and opens smoothly. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model aims to provide a vehicle side swing door.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a vehicle side swing door,

[0007] It includes a rotating arm assembly for driving the door to perform opening and closing actions relative to the vehicle body opening, an opening and closing guide assembly arranged on the closed end of the door and the vehicle body, and a track guide assembly connected between the door and the rotating arm assembly;

[0008] The swing arm assembly includes an active swing arm and a driven swing arm, the active swing arm is rotatably connected between the vehicle door and the vehicle body, and one end of the driven swing arm is rotatably set on the vehicle body, the trajectory guide assembly applies a restraining force to the front closed end of the vehicle door, and keeps the rear closed end of the vehicle 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 the opening and closing guide assemblies disengage from each other during the opening action, and cooperate with each other during the closing action to the fully closed action.

[0009] Furthermore, the track guide assembly includes a track seat fixed to the front side of the vehicle door, an adjustment arm rotatably arranged between the track seat and the door side end of the driven rotating arm, and a telescopic rod connected to the driven rotating arm and the rear side of the vehicle door, and the driven rotating arm is constrained to rotate within the track seat.

[0010] Furthermore, the telescopic rod applies an auxiliary force at least during the opening action of the vehicle door being ready to be opened.

[0011] Furthermore, the track seat is provided with a lifting section corresponding to the opening action and the closing action, and a U-shaped section corresponding to the door from lifting to full opening and from full opening to closing, and the lifting section and the U-shaped section are both arranged in an arc shape.

[0012] Furthermore, the vehicle door approaches the rear portion of the vehicle body opening in a posture parallel to the vehicle body in a fully opened state, and the swing arm assembly rotates to the rear side of the vehicle body opening.

[0013] Furthermore, the rotating arm assemblies are mutually closed between the vehicle body opening and the vehicle door when the vehicle door is in a fully closed state.

[0014] Furthermore, the opening and closing guide assembly includes a guide block arranged on the front closed end of the vehicle door, and a guide seat arranged on the front closed end of the vehicle body, the guide seat having an outer guide portion and an inner guide portion spaced apart in the front and rear direction of the vehicle body, and the guide block is supported between the outer guide portion and the inner guide portion in the closed position.

[0015] Furthermore, a guide space is provided in the guide seat to allow the guide block to swing toward the inner side of the vehicle body during the opening action, and the guide block is pulled out of the guide space in an inclined posture through the traction of the rotating arm assembly and the track guide assembly.

[0016] Furthermore, the active rotating arm is connected to a driving device, which includes a driving seat arranged at the rear end of the vehicle body opening, a motor arranged on the driving seat and at least one transmission component, and the active rotating arm is rotatably arranged on the driving seat and engaged with the transmission component.

[0017] Furthermore, a protective shell is provided outside the active rotating arm, and when the door is fully closed, the protective shell extends inwardly from the vehicle width direction into the vehicle interior space, and the active rotating arm extends between the door and the vehicle body in the door opening trajectory.

[0018] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0019] In the utility model, a track guide assembly is arranged between the vehicle body and the driven rotating arm, and an opening and closing guide assembly is arranged between the vehicle body and the closed end of the door. In the closed position, the opening and closing guide assembly can effectively support the door and limit the displacement of the door in the vehicle width direction, thereby reducing shaking and vibration, as well as noise generated during driving. At the same time, due to the constraints of the inner guide part and the outer guide part on the guide block, the door can be kept in the closed position when the side of the vehicle is subjected to an impact load, thereby improving safety.

[0020] During the opening process, the trajectory guide assembly is able to limit the trajectory of the driven pivot arm, so that when the active pivot arm actuates the rear end of the door to rotate and expand, the door remains pulled away from the front closed end of the car body with its rear end raised. During this process, the opening and closing guide assembly can adapt to the door trajectory driven by the pivot arm assembly, thereby ensuring that the door can be opened and closed without interference.

[0042] 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.

[0043] 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.

[0044] like Figure 1-20 As shown, a vehicle side swing door comprises a rotating arm assembly 3 for driving a vehicle door 1 to perform an opening and closing action relative to a vehicle body opening 2.1, an opening and closing guide assembly 4 arranged on a closed end between the vehicle door 1 and the vehicle body 2, and a track guide assembly 5 connected between the vehicle door 1 and the rotating arm assembly 3, wherein the opening and closing guide assembly 4 is arranged at a front closed end of the vehicle door 1, and the track guide assembly 5 is arranged close to the front closed end of the vehicle door 1;

[0045] like Figure 4 and Figures 8 to 11 As shown, the arm assembly 3 is arranged on one side of the interior trim panel of the vehicle door 1, and the arm assembly 3 includes an active arm 3.1 and a driven arm 3.2. One end of the active 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 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 arm 3.1 to drive the vehicle door 1 and pull the driven arm 3.2 to move;

[0046] 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 track guide assembly 5, and the distance between the door side end of the driven rotating arm 3.2 and the vehicle door 1 is rotatably connected, and the distance changes with the rotation of the active rotating arm 3.1 and through the track guide assembly 5. The track guide assembly 5 is specifically arranged between the door side rotation end of the driven rotating arm 3.2 and the vehicle door 1;

[0047] The track guide assembly 5 pulls the front closing end 1.1 of the door, limits the track of the door side rotating end of the driven rotating arm 3.2, and keeps the rear closing end 1.2 of the door in an outwardly inclined posture 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 action and closing action, the guide opening and closing assemblies between the door 1 and the vehicle body 2 are ready to be separated from each other, and the front closing end 1.1 of the door is still close to the front side of the vehicle body opening 2.1;

[0048] from Fig. 9 It can be seen that the opening and closing guide assembly 4 is arranged between the front closed end of the vehicle door 1 and the vehicle body 2, and cooperates with each other when the vehicle door 1 is in a fully closed state to limit the position between the closed end of the vehicle door 1 and the closed end of the vehicle body 2, thereby ensuring the stability of the vehicle door 1 in a closed state, while the other end away from the vehicle door 1 is held by the drive unit 6.

[0049] The opening and closing guide components 4 cooperate with each other and disengage from each other as the door 1 swings during the opening action. The opening and closing guide components 4 engage with each other and gradually abut against each other in the vehicle width and closing direction of the body 2 as the door 1 swings during the closing action.

[0050] Therefore, when the opening action is completed, the front closed end 1.1 of the door tilts toward the rear side of the vehicle body 2, thereby breaking away from the interference position with the end of the other side door 1 and the obstruction of the opening and closing guide assembly 4. After that, the door 1 can be unfolded in a free posture. Of course, the track guide assembly 5 is still constrained by the door-side rotating end of the driven rotating arm 3.2 to prevent the front closed end 1.1 of the door from excessively swinging in the outer direction of the vehicle width.

[0051] The above-mentioned opening and closing guide assembly 4 and track guide assembly 5 ensure that the front closing end of the vehicle door 1 does not interfere with the vehicle body 2 or the edge of another vehicle door 1 during the opening action and the closing action.

[0052] (Active rotating arm 3.1 and driven rotating arm 3.2)

[0053] like Figures 9 to 11 As shown, when the door 1 is in the fully closed position, the arm assemblies 3 are closed together between the vehicle body opening 2.1 and the door 1, and the rotating connection ends of the active arm 3.1 and the driven arm 3.2 on the door 1 and the vehicle body 2 are staggered front and rear with respect to the direction of the vehicle body 2, and the door-side rotating ends of the driven arm 3.2 and the adjusting arm 5.4 are arranged closer to the front closing end 1.1 of the door than the door 1 rotating end of the active arm 3.1, so that the door-side rotating end of the driven arm 3.2 can cooperate with the track guide assembly 5 on the front closing end 1.1 of the door to limit the posture of the front closing end 1.1 of the door during the preparation for opening and the action of about to fully close the door 1, that is, to constrain the posture of the door 1 with its rear closing end extending outward in the vehicle width direction compared with the front closing end.

[0054] 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 2 rotating end 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 2 rotating end of the active rotating arm 3.1 is located behind the body 2 rotating end of the driven rotating arm 3.2.

[0055] When the door 1 is fully opened, the door 1 approaches the rear of the vehicle body opening 2.1 in a posture roughly parallel to the vehicle body 2, and the swing arm assembly 3 rotates to the rear side of the vehicle body opening 2.1. 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 vehicle body opening 2.1, 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 vehicle body opening 2.1, so as to release the vehicle body opening 2.1 and facilitate the entry and exit of passengers;

[0056] The opening trajectory of the door 1 also includes a maximum outward movement state 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. When the door 1 is fully closed, the active rotating arm 3.1 and the driven rotating arm 3.2 are mutually closed between the vehicle body opening 2.1 and the door 1, and the two are roughly parallel.

[0057] 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.

[0058] Thus, the vehicle door 1 is opened and closed by the quadrilateral link structure formed by the above-mentioned rotating arm assembly 3 .

[0059] Specifically, the door-side rotating 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 rear wheel hub of the body 2 and below the C-pillar of the body;

[0060] The door side end of the driven rotating arm 3.2 is arranged at the lower part of the door 1, and the body 2 rotating 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.

[0061] Reference Fig.10 and Fig.11 Specifically, a protective shell 3.11 is provided outside the active rotating arm 3.1, and the protective shell 3.11 is preferably fixed on the outside of the active rotating arm 3.1. When the door 1 is fully closed, the active rotating arm 3.1 extends inward from the door 1 into the interior space of the vehicle. At this time, the protective shell 3.11 can perform the function of an armrest in the vehicle. In addition, the protective shell 3.11 and the active rotating arm 3.1 extend from the rear stop of the vehicle body opening 2.1 to a position close to the center of mass of the door 1, and the active rotating arm 3.1 extends between the door 1 and the vehicle body 2 in the opening trajectory of the door 1. At this time, the active rotating arm 3.1 and the protective shell 3.11 can function as an armrest for passengers to enter and exit the vehicle.

[0062] (Opening and closing guide component 4)

[0063] Further references Figure 4 and Figures 14 to 18 As shown, specifically, the opening and closing guide assembly 4 includes a guide block 4.2 arranged on the front closed end 1.1 of the vehicle door, and a guide seat 4.1 arranged on the front closed end of the vehicle body 2, the guide seat 4.1 has an outer guide portion 4.3 and an inner guide portion 4.4 spaced apart in the front and rear directions of the vehicle body 2, and the guide block 4.2 is supported between the outer guide portion and the inner guide portion in the closed position.

[0064] The front closed end of the vehicle body 2 refers to a portion on the vehicle body that is closed with the front closed end 1.1 of the door.

[0065] Specifically, the outer guide portion 4.3 constrains the guide block 4.2 in the vehicle width outer direction, and the inner guide portion 4.4 is supported by the guide block 4.2 in the vehicle width inner direction. In the fully closed state, the guide block 4.2 is abutted against the inner side of the outer guide portion 4.3 and the outer side of the inner guide portion 4.4.

[0066] Specifically, when the vehicle door 1 is about to be opened or closed, the guide block 4.2 is constrained in the guide channel defined by the inner guide portion 4.4 and the outer guide portion 4.3.

[0067] As a further embodiment of the outer guide portion 4.3 and the inner guide portion 4.4, there are arcuate surfaces 4.5 arranged opposite to each other between the outer guide portion 4.3 and the inner guide portion 4.4, and the arcuate surfaces 4.5 are spaced apart in the width direction of the vehicle body 2 so that the guide block 4.2 can cooperate with at least one of the arcuate surfaces 4.5 when the vehicle door 1 performs an opening and closing action.

[0068] The guide block 4.2 is arranged in an arc strip shape as a whole, and the guide block 4.2 is provided with a guide matching surface 4.21 on the inner and outer sides of the vehicle body 2, and the guide matching surface 4.21 is connected at the end of the guide block 4.2 to form a guide protrusion 4.22, and in the fully closed state, the guide protrusion 4.22 abuts against the end of the arc surface 4.5 of the outer guide portion 4.3, and the guide block 4.2 is restricted from moving outward in the vehicle width direction by the two arc surfaces 4.5, thereby effectively avoiding the shaking and noise generated by the vehicle door 1 during driving, especially the matching stability between the front closed end 1.1 of the vehicle door and the vehicle body 2;

[0069] In the opening action of preparing to open, the guide matching surface 4.21 is used to match with the arc surface 4.5 between the outer guide part 4.3 and the inner guide part 4.4 to play a certain guiding role.

[0070] like Fig.18As shown, in the process of preparing to open, the rear closing end 1.2 of the door is expanded toward the outside of the vehicle width under the actuation of the active rotating arm 3.1, while the front closing 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 that the front closing end of the door 1 can be smoothly separated from the vehicle body 2 to Fig. 20 status.

[0071] Specifically, the outer guide portion 4.3 is arranged with an opening facing the guide block 4.2, and the inner guide portion 4.4 is located in the opening direction of the outer guide block 4.2. The guide block 4.2 can enter and leave the guide channel through the opening. The outer guide portion 4.3 is closed at one end away from the inner guide portion 4.4, so that the guide block 4.2 abuts against the front of the vehicle body 2. The outer guide portion 4.3 further expands toward the outside of the vehicle width, thereby facilitating the detachment and entry of the guide block 4.2.

[0072] As a further embodiment of the inner guide portion 4.4, 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 ensuring the supporting effect in the vehicle width direction while reducing the resistance of sliding friction.

[0073] 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. For example, the inner guide portion 4.4 may be a rotating roller, and the arc convex portion is formed on the rotating roller.

[0074] In other embodiments, in order to further optimize the opening and closing 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.

[0075] In this embodiment, in order to adapt to the accompanying lifting action of the front closed end 1.1 of the vehicle door, a guide space 4.31 is provided at the front end of the outer guide portion 4.3 to allow the guide block 4.2 to be offset toward the side of the vehicle body 2 during the opening action. As a result, through the swing of the vehicle door 1 in the action of preparing to open, the guide block 4.2 rotates in the guide seat 4.1 and follows the vehicle door 1 to be adjusted to a tilted posture in the guide space 4.31, wherein the constraint trajectory of the track guide component 5 for the driven rotating arm 3.2 is arc-shaped, thereby being able to optimize the complete disengagement action of the guide block 4.2 in the guide channel on the basis of the arc-shaped guide block 4.2.

[0076] Preferably, there are two groups of opening and closing guide assemblies 4 , which are respectively arranged on the upper and lower sides of the closed ends of the vehicle door 1 and the vehicle body 2 to further enhance the stabilization and retention of the vehicle door 1 .

[0077] (Trajectory guide component 5)

[0078] like Figures 4 to 11 ,as well as Fig.19 As shown, specifically, the track guide assembly 5 includes a track seat 5.1 fixed to the front side of the vehicle door 1, an adjustment arm 5.4 rotatably arranged between the track seat 5.1 and the door side end of the driven rotating arm 3.2, and a telescopic rod 5.5 rotatably connected between the driven rotating arm 3.2 and the rear side of the vehicle door 1 at both ends, and the driven rotating arm 3.2 is constrained to slide in the track seat 5.1;

[0079] Among them, the track seat 5.1 is arranged on the inner side of the vehicle door 1 and protrudes toward the inner side of the vehicle body 2. The telescopic rod 5.5 applies an auxiliary force at least when the vehicle door 1 is ready to be opened, that is, the telescopic rod 5.5 has a tendency to extend, and this tendency is acted upon as the vehicle door 1 is opened. Through the auxiliary force of the telescopic rod 5.5, it is beneficial for the vehicle door 1 to switch from the opening action of preparing to open to the unfolded state, and the smoothness of the opening track in the unfolded state. Therefore, during the closing process of the vehicle door 1, the telescopic rod 5.5 can provide a buffering force to avoid inertial collision of the vehicle door 1 when it is about to be closed.

[0080] As a further implementation of the telescopic rod 5.5, the telescopic rod 5.5 and the driven rotating arm 3.2 are arranged at the same height.

[0081] Specifically, the telescopic rod 5.5 exerts a steady linear force during the opening process. Optionally, the telescopic rod 5.5 may be a gas spring or an electric support rod.

[0082] As a further embodiment of the driven rotating arm 3.2, the driven rotating arm 3.2 has a guide shaft 3.21 on the side corresponding to the vehicle door 1, and the guide shaft 3.21 is constrained to slide in the track seat 5.1.

[0083] As a further implementation of the track seat 5.1, the track seat 5.1 is provided with a raised section 5.2 corresponding to the preparation for opening action and the 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 inside of the vehicle width. The raised section 5.2 extends outside the vehicle width along the end of the U-shaped section 5.3.

[0084] The guide shaft 3.21 mentioned above constitutes the door-side rotating end of the driven rotating arm 3.2, and the connecting portion of the adjusting arm 5.4 on the track seat 5.1 serves as the door-side rotating end of the adjusting arm 5.4. By sliding the guide shaft 3.21 in the track seat 5.1, the distance between the adjusting arm 5.4 and the door-side rotating end is adjusted, thereby limiting the posture of the front closed end of the vehicle door 1 during opening and closing.

[0085] The guiding direction of the lifting section 5.2 matches the guiding channel. When the door 1 is ready to be opened, the relative positions of the driven rotating arm 3.2 and the adjusting arm 5.4 in the track seat 5.1 change from Fig. 9 Exercise to Fig.19 , the driven rotating arm 3.2 rotates under the traction of the car 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 guide shaft 3.21 from the opening action, so that the distance between the guide shaft 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 to rotate. At this time, the front closed end 1.1 of the car door is delayed in unfolding before the rear closed end 1.2 of the car door under the guidance of the lifting section 5.2, so that the front closed end of the car door 1 moves in a tilted posture to avoid the interference of the car body 2 and the other side door 1. At the same time, the guide block 4.2 is executing the Fig.18 The guide seat 4.1 shown in the figure disengages from the guide seat 4.1 until it moves to the Fig. 20 The door 1 is in an obstacle-free posture, and then the door 1 is driven to continue to rotate by the rotating arm, and the adjusting arm 5.4 abuts against the track seat 5.1. At this time, the guide block 4.2 is separated from the guide seat 4.1, and the front closed end of the door 1 is driven and unfolded in the vehicle width direction to a position close to the rear closed end 1.2 of the door in an arc-shaped trajectory.
