Description

Technical Field

[0001] This disclosure relates to a door shifting system including a shifting mechanism and an arm structure. The arm structure is arranged between the vehicle body structure and the door. The arm structure is pivotally connected to the vehicle body structure at its inner end and pivotally connected to the door at its outer end. The arm structure is configured to shift the door between a closed position and an open position. This disclosure also relates to a vehicle including the door shifting system and a method for operating the door shifting system. Background Technology

[0002] Door systems are used to cover openings in the vehicle body structure that lead to interior compartments. Door systems typically include a door shifting mechanism that moves the door relative to the opening between a closed position and an open position.

[0003] Traditionally, articulated doors are used, which move between open and closed positions relative to the vehicle body structure via a swinging motion. The doors are attached to the body structure via hinges or similar devices. Traditional articulated door systems are simple in structure, but require relatively large external space when fully opened.

[0004] Sliding doors are becoming increasingly popular and, as an alternative, are mounted to or suspended relative to the vehicle body structure via a track system or a combination of track and hinges. By sliding horizontally along the vehicle body structure, the sliding door is moved between open and closed positions relative to the structure. Sliding door systems and other alternative door systems offer the advantage of requiring less space for opening and closing compared to hinged door solutions. Current sliding door system solutions typically use mechanisms that increase the height of the bottom beam in the bottom beam area, resulting in a higher span for accessing the vehicle's interior compartments compared to traditional hinged door systems. Another issue with sliding doors is that the sliding movement of the door is limited by the mechanism.

[0005] A door connected to the vehicle body structure using an arm can be used as an alternative to a sliding door, where the arm moves relative to the door and the body structure as the door shifts between a closed and open position. When using a movable arm, it can be difficult to open and close the door efficiently due to the door's displacement kinematics and weaker geometry, requiring increased opening or closing forces during operation. This increased force can cause stress on the electric motor used to open or close the door, or lead to inefficient door operation if the door is opened or closed manually. Sometimes, gas springs are used to support the final closing operation at the end of a closing cycle. The problem with using gas springs is that a force from the gas spring needs to be overcome when opening the door.

[0006] Therefore, there is a need for an improved door shifting system with a movable arm, wherein the door can be opened and closed efficiently using a robust and reliable door shifting function. Summary of the Invention

[0007] The purpose of this disclosure is to provide a door shifting system that avoids the aforementioned problems, a vehicle including the door shifting system, and a method for operating the door shifting system. This purpose is achieved at least in part by the features of the independent claims. The dependent claims cover further improvements to the door shifting system and the method for operating the door shifting system.

[0008] This disclosure relates to a door shifting system, which includes a shifting mechanism and an arm structure. The arm structure is configured to be disposed between a vehicle body structure and a door. The arm structure is configured to be pivotally connected to the vehicle body structure at an inner end and to the door at an outer end. The arm structure is configured to shift the door between a closed position and an open position. The shifting mechanism includes a first rod and a second rod, which are pivotally connected to each other via a rod pivot point. The first rod is pivotally connected to the arm structure, and the second rod is configured to be pivotally connected to the vehicle body structure. The shifting mechanism also includes a spring extending between the inner end of the arm and the first rod. The spring is configured to apply an opening force to the arm structure when the door is shifted from a closed position to an open position, and to apply a closing force to the arm structure when the door is shifted from an open position to a closed position. During the transition from the closed position to the open position, the first and second levers pivot relative to each other about the lever pivot point along a first bending direction. During the transition from the open position to the closed position, the first and second levers pivot relative to each other about the lever pivot point along a second bending direction opposite to the first bending direction.

[0009] The advantage of these features is that the door shifting system supports efficient opening and closing of the door by applying opening and closing forces during opening and closing operations. This force supports opening and closing operations even in cases of weak geometry and alleviates stress on the electric motor used to open or close the door. The first and second levers provide efficient door operation through pivoting along a first and second bending direction, respectively. When the door is shifted from the closed position to the open position, a spring applies an opening force to the arm structure, and when the door is shifted from the open position to the closed position, a spring applies a closing force to the arm structure. The door shifting system achieves efficient opening and closing operations using robust and reliable door shifting functionality.

[0010] In one embodiment, during the initial opening displacement from the closed position to the open position, the first inner side of the first rod and the second inner side of the second rod pivot about a rod pivot point toward each other along a first bending direction. During the final opening displacement, the first inner side and the second inner side pivot away from each other about a rod pivot point along the first bending direction. The first bending direction is defined as a position of the first rod and the second rod relative to each other in which the first inner side and the second inner side are arranged to face each other. In the first bending direction, the first rod and the second rod are pivoted such that the first inner side and the second inner side face each other.

[0011] In one embodiment, during the initial closing shift from the open position to the closed position, the first outer side of the first rod and the second outer side of the second rod are pivoted toward each other about the rod pivot point along a second bending direction. During the final closing shift, the first outer side and the second outer side are pivoted away from each other about the rod pivot point along the second bending direction. The second bending direction is defined as a position of the first and second rods relative to each other, wherein (unlike the previous configuration) the first outer side and the second outer side are arranged to face each other. In the second bending direction, the first and second rods are pivoted such that the first outer side and the second outer side face each other.

[0012] In one embodiment, the arm structure is pivotally connected to the vehicle body structure at its inner end via an inner arm pivot point. The inner arm pivot point is used for efficient displacement of the arm structure.

[0013] In one embodiment, the first outer end of the first rod is pivotally connected to the inner end of the arm structure via an external pivot point. The first inner end of the first rod is pivotally connected to the second rod via a pivot point. The second outer end of the second rod is pivotally connected to the first rod via a pivot point. The second inner end of the second rod is pivotally connected to the vehicle body structure via an internal pivot point. The corresponding pivot points connect the first and second rods to each other, connecting the first rod to the arm structure and the second rod to the vehicle body structure for efficient operation of the shifting mechanism.

[0014] In one embodiment, the inner end of the arm structure includes a first extension. The first extension is configured to extend inward from the inner end of the arm toward the inside of the vehicle when the door is positioned in the closed position. An external pivot point is disposed on the first extension spaced apart from the internal pivot point. The first extension provides suitable geometry for the door shifting system.

[0015] In one embodiment, the inner end of the arm structure includes a second extension. The second extension is configured to extend outward from the inner end of the arm toward the outside of the vehicle when the door is positioned in the closed position. A spring is attached to the second extension. The second extension provides efficient positioning of the spring relative to the first lever during door opening and closing operations.

[0016] In one embodiment, a first extension and a second extension are arranged on a common support structure, which is attached to the arm structure and forms part of the arm structure. This common support structure simplifies the structure of the door shifting system.

[0017] In one embodiment, the arm structure is configured to pivot relative to the vehicle body structure and the door when the door is displaced between a closed position and an open position. As the arm structure pivots relative to the vehicle body structure, a first link is configured to pivot relative to the arm structure and a second link, and the second link is configured to pivot relative to the vehicle body structure and the first link. This pivoting motion supports the application of opening and closing forces.

[0018] In one embodiment, the spring is configured as a coil spring, which applies an opening force to the arm structure when the door is moved from the closed position to the open position, and applies a closing force to the arm structure when the door is moved from the open position to the closed position. The coil spring provides a simple and reliable spring construction.

[0019] This disclosure also relates to vehicles including the door shifting system described above.

[0020] This disclosure also relates to a method for operating a vehicle door shifting system, the system including a shifting mechanism and an arm structure. The arm structure is arranged between a vehicle body structure and a vehicle door. The arm structure is pivotally connected to the vehicle body structure at an inner end and pivotally connected to the vehicle door at an outer end. The arm structure is configured to shift the vehicle door between a closed position and an open position. The shifting mechanism includes a first rod and a second rod, which are pivotally connected to each other via a rod pivot point. The first rod is pivotally connected to the arm structure, and the second rod is pivotally connected to the vehicle body structure. The shifting mechanism also includes a spring extending between the inner end of the arm and the first rod. The method includes the steps of: pivoting the first and second rods relative to each other along a first bending direction about the rod pivot point during the shifting of the vehicle door from the closed position to the open position, and applying an opening force to the arm structure by means of the spring when the vehicle door is shifted from the closed position to the open position. During the movement of the door from the open position to the closed position, the first and second rods are pivoted relative to each other about the rod pivot point along a second bending direction opposite to the first bending direction, and when the door is moved from the open position to the closed position, a closing force is applied to the arm structure by the spring.

[0021] The advantage of these features is that the method for operating the door shifting system supports efficient door opening and closing by applying opening and closing forces during opening and closing operations. This force supports opening and closing operations even in cases of weak geometry and alleviates stress on the electric motor used to open or close the door. The first and second levers provide efficient door operation through pivoting along a first and second bending direction, respectively, wherein when the door is shifted from the closed position to the open position, a spring applies an opening force to the arm structure, and when the door is shifted from the open position to the closed position, a spring applies a closing force to the arm structure. This method achieves efficient door opening and closing operations using robust and reliable door shifting functionality.

[0022] In one embodiment, the method further includes the steps of: during an initial opening displacement from the closed position to the open position, pivoting a first inner side of the first rod and a second inner side of the second rod about a rod pivot point toward each other along a first bending direction; and during a final opening displacement, pivoting the first inner side and the second inner side away from each other along the first bending direction about the rod pivot point. The first bending direction is defined as the position of the first rod and the second rod relative to each other, wherein the first inner side and the second inner side are arranged to face each other. In the first bending direction, the first rod and the second rod are pivoted such that the first inner side and the second inner side face each other.

[0023] In one embodiment, the method further includes the steps of: during an initial closing shift from the open position to the closed position, pivoting a first outer side of the first rod and a second outer side of the second rod about a rod pivot point toward each other along a second curvature direction; and during a final closing shift, pivoting the first outer side and the second outer side away from each other along the second curvature direction about the rod pivot point. The second curvature direction is defined as the position of the first rod and the second rod relative to each other, wherein, alternatively, the first outer side and the second outer side are arranged to face each other. In the second curvature direction, the first rod and the second rod are pivoted such that the first outer side and the second outer side face each other.

[0024] In one embodiment, the spring applies an opening force to the arm structure during the initial opening displacement and / or the final opening displacement, and / or, the spring applies a closing force to the arm structure during the initial closing displacement and / or the final closing displacement. In this way, the spring efficiently applies both opening and closing forces. Attached Figure Description
