Description

Technical Field

[0002] The door stopper is a crucial component in a car's door system. Its primary function is to limit the door's opening angle, ensuring it remains open during operation, and ensuring stability and safety during both opening and closing. The door stopper consists of a main body and a main arm. The main body slides on the arm to achieve its limiting effect. The centerline of the main arm's contour (referred to as the main arm centerline) is a key factor influencing smooth door opening and closing, as well as any unusual noises.

[0003] In related technologies, a contour centerline is first determined using a curve formula, and then this contour centerline is repeatedly adjusted and verified. This requires a huge amount of manual work, the establishment of a relevant intelligent model, high computing power requirements, and high implementation difficulty, resulting in low efficiency in determining the contour centerline of the limiter main arm. Therefore, improving the efficiency of determining the contour centerline of the limiter main arm is a technical problem that needs to be solved urgently. Summary of the Invention

[0057] The embodiment of the present application solves the technical problem of low efficiency in determining the contour center line of the main arm of a door stopper in the prior art by providing a method for determining the center line of the main arm of a door stopper.

[0058] The technical solution of the embodiment of the present application is to solve the above technical problems, and the overall idea is as follows:

[0059] The embodiment of the present application determines the center line to be verified between the limiter axis and the end of the limiter at the preset maximum opening position according to the preset closing position and the preset maximum opening position corresponding to the limiter body of the limiter and the sample curve function set; the preset closing position is the position corresponding to the limiter body when the door is closed, and the preset maximum opening position is the position corresponding to the limiter body when the door is fully opened; the center line to be verified is controlled to rotate around the limiter axis from the maximum opening state of the door to the closed state of the door, so as to obtain the center line to be moved; the limit is controlled The axis of the stopper moves in the opposite direction of the door opening on a preset arc, and drives the center line to be moved and the end to move adaptively on the center of the stopper; the preset arc is obtained by rotating the axis of the stopper with the hinge axis of the door as the center, and the center of the stopper is the center point corresponding to the preset closed position of the stopper body; during the adaptive movement process, when the center line to be moved does not exceed the edge area corresponding to the openings on both sides of the stopper body, and the end does not exceed the safety gap between the inner plate and the glass panel of the door, the center line to be verified is determined as the target center line of the stopper main arm. It can be seen that the embodiment of the present application determines the center line to be verified by combining the preset closed position and the preset maximum opening position of the stopper with the sample curve function set, and verifies whether the center line to be moved meets the design requirements during the adaptive movement process, thereby quickly determining the center line of the stopper main arm, reducing the workload of the design process, reducing the requirement for computing power, and at the same time being able to adapt to different vehicle models and stopper layout spaces, quickly adapt to new design requirements, improve the smoothness and stability of door opening and closing, and thus enhance the user's driving and riding experience.

[0060] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0061] First, the term "and / or" as used herein simply describes a relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A alone, A and B together, or B alone. Furthermore, the character " / " in this document generally indicates an "or" relationship between the associated objects.

[0062] With the development of the automotive industry and market demand, a variety of new vehicle models are entering the development and production stages. During this process, doors, as a crucial component of a vehicle, have a quality that directly impacts its sales after launch. Among the factors that evaluate door quality, opening and closing smoothness and the presence of creaking noise are considered key concerns. Door stoppers, as key components that limit the door's opening angle, can directly impact both opening and closing smoothness and creaking noise, making their design particularly crucial.

[0063] During the design process of the door limiter, it needs to be customized according to the specific settings of the door, mainly including the door glass panel, door opening, door inner panel and door stamping process, to ensure that the limiter meets the requirements of the door operation quality and layout space.

[0064] The present application embodiment first describes the structure and principle of the door stopper. Figure 1 As shown, the limiter mainly includes: a limiter main arm 2, a limiter body 1 nested in the limiter main arm 2, and an end cap 3 mounted at the end of the limiter main arm 2. The limiter body 1 is connected to the vehicle door, and the range of motion of the limiter body 1 and the limiter main arm 2 is limited to the enclosed space formed by the vehicle door's inner panel 5 and glass panel 6. When the vehicle door switches from a closed state to a fully open state, the vehicle door drives the limiter body 1 to rotate about the vehicle door's hinge axis 7 from a preset closed position 11 to a preset maximum opening position 12, while simultaneously sliding from one end of the limiter main arm 2 to the other. The limiter main arm 2 rotates about the limiter axis 4 to follow the limiter body 1 by a corresponding angle.

[0065] It should be noted that in Figure 1 The figure shows the states of the limiter main arm 2 before and after rotation, and shows the states of the inner plate 5 and the glass panel 6 before rotation, but does not show the states of the inner plate 5 and the glass panel 6 after rotation. Those skilled in the art can understand the adaptive change states, so they will not be elaborated here.

[0066] In the prior art, there are two methods for determining the limiter main arm 2: the first method is to deduce the contour center line of the limiter main arm 2 based on the vertical relationship between the limiter main arm 2 and the limiter body 1 under different door openings; the second method is to determine a contour center line through a preset curve formula, and then repeatedly check and adjust it to finally obtain the contour center line of the limiter main arm 2 that meets the requirements.

[0067] However, both of these methods require numerous calculation steps and complex work, resulting in a low efficiency in determining the centerline of the main arm 2. Furthermore, if the main arm 2 exhibits a significant S-shape due to the influence of the door inner panel 5, glass panel 6, hinge axis 7, and the stamping process, the arm 2 will be stretched and deformed at maximum opening, increasing the likelihood of abnormal noise.

[0068] In order to solve the above problems, an embodiment of the present application provides a method for determining the center line of the main arm of a vehicle door limiter, which can be implemented in simulation software to determine the center line of the main arm of the limiter during the design process, including steps S1 to S4.

[0069] Step S1, determining a center line to be verified between the stopper axis 4 and the end 3 of the stopper at the preset maximum opening position 12 based on a preset closed position 11 and a preset maximum opening position 12 corresponding to the stopper body 1 of the stopper and a sample curve function set; the preset closed position 11 being the position corresponding to the stopper body 1 in the closed state of the vehicle door, and the preset maximum opening position 12 being the position corresponding to the stopper body 1 in the maximum open state of the vehicle door;

[0070] Step S2, controlling the center line to be verified to rotate around the axis of the stopper 4 from the maximum door opening state to the door closing state to obtain the center line to be moved;

[0071] Step S3: Control the stopper axis 4 to move in the opposite direction of the door opening direction along a preset arc, and drive the center line to be moved and the end 3 to move adaptively on the stopper center; the preset arc is obtained by rotating the stopper axis 4 around the hinge axis 7 of the door as the center, and the stopper center is the center point of the stopper body 1 corresponding to the preset closed position;

[0072] Step S4, during the adaptive movement process, when the center line to be moved does not exceed the edge area corresponding to the openings on both sides of the limiter body 1, and the end 3 does not exceed the safety gap between the inner panel 5 and the glass panel 6 of the car door, the center line to be verified is determined as the target center line of the limiter main arm 2.

[0073] Regarding step S1, based on the preset closing position 11 and the preset maximum opening position 12 corresponding to the limiter body 1 of the limiter and the sample curve function set, determine the center line to be verified between the limiter axis 4 and the end 3 of the limiter at the preset maximum opening position 12; the preset closing position 11 is the position corresponding to the limiter body 1 when the car door is closed, and the preset maximum opening position 12 is the position corresponding to the limiter body 1 when the car door is fully opened.

[0074] Step S1 may specifically include steps S11 to S14.

[0075] Step S11: When the stopper body 1 is in the preset closed position 11, a radial line is obtained by connecting the stopper axis 4 and the center of the proximal shell surface 101 of the stopper body 1 on the side close to the stopper axis 4; the radial line is perpendicular to the proximal shell surface 101;

[0076] Step S12, controlling the radial connection line to rotate around the axis of the stopper 4 by a preset angle to obtain a starting center line; the preset angle is the rotation angle of the stopper body 1 corresponding to the door switching from the closed state to the maximum open state;

[0077] Step S13, when the stopper body 1 is at the preset maximum opening position 12, based on the center of the distal shell surface 102 of the stopper body 1 on the side away from the stopper axis 4, a preset distance is extended in a direction perpendicular to the distal shell surface 102 and away from the stopper axis 4 to obtain the terminal centerline;

[0078] Step S14 , determining a centerline to be verified formed by connecting the starting centerline and the ending centerline according to the starting centerline, the ending centerline and the sample curve function set.

[0079] Regarding step S11 and step S13, Figure 3 and Figure 4a As shown, the present application only requires that the proximal shell surface 101 be perpendicular to the limiter main arm 2 at the preset closed position 11 and that the distal shell surface 102 be perpendicular to the limiter main arm 2 at the preset maximum opening position 12. A perpendicular relationship is not required at other positions, and a reasonable space gap is sufficient. This avoids the need in the prior art to ensure that the limiter is perpendicular to the limiter main arm 2 at each movement position, thereby deriving the center line of the limiter main arm 2. This saves design steps and effectively improves determination efficiency.

[0080] Regarding step S12, the preset angle is the rotation angle of the stopper body 1 corresponding to the door switching from the closed state to the maximum open state. The preset angle is the sum of the preset door opening and the preset compensation angle, that is, β = α + δ, where β is the preset angle, α is the door opening, and δ is the compensation angle. Exemplarily, δ is 4°.

[0081] Regarding step S13, when the stopper body 1 is at the preset maximum opening position 12, the center of the distal shell surface 102 of the stopper body 1 away from the stopper axis 4 is extended along a direction perpendicular to the distal shell surface 102 and away from the stopper axis 4 by a preset distance to obtain the terminal center line. Figure 4aAs shown, line segment E1 F1 represents distal housing surface 102. Line segment N extends from the midpoint of line segment E1 F1, perpendicularly and away from the axis of the stopper, to point M, forming line segment NM, the distal centerline. The preset distance is determined by the extended length of the stopper's tip 3. For example, the preset distance is 15 mm.

[0082] Regarding step S14, the sample curve function set is a function set connecting two determined points through a certain curvature. In this embodiment, the starting center line and the ending center line are connected through a preset curvature to form the center line to be verified.

[0083] The following combination Figure 4a-4c The structural diagram provided is used to detail the process of obtaining the center line to be moved in the embodiment of the present application.

[0084] Point A represents the axis of the limiter, point B represents the axis of the hinge, line segment IJ represents the inner panel 5 of the vehicle door, line segment GH represents the glass panel 6 of the vehicle door, line segment CD represents the proximal shell surface when the limiter body 1 is in the preset closed position 11, line segment EF represents the distal shell surface when the limiter body 1 is in the preset closed position 11, line segment C1 D1 represents the proximal shell surface when the limiter body 1 is in the preset maximum opening position 12, E1 F1 represents the distal shell surface when the limiter body 1 is in the preset maximum opening position 12, K is the midpoint of line segment CD, N is the midpoint of line segment E1 F1, and the angle between line segment AK and line segment AL is β.

[0085] like Figure 4a As shown, at the preset closed position 11, the radial line AK is obtained by connecting the stopper axis point A and the midpoint K of the proximal shell surface CD. The radial line AK is then rotated clockwise by a preset angle β to obtain the starting centerline AL. At the preset maximum open position 12, the terminal centerline NM is obtained by extending the predetermined distance from the midpoint N to the distal end perpendicular to the distal shell surfaces E1 F1.

[0086] like Figure 4b As shown, by using the sample curve function set, the starting center line AL and the ending center line NM are connected to obtain the center line AM to be verified. Figure 4c As shown, the center line to be verified AM is rotated counterclockwise by β to obtain the center line to be moved AM1.

[0087] Regarding step S2, the center line to be verified is controlled to rotate around the limiter axis 4 from the maximum door opening state to the door closing state to obtain the center line to be moved.

[0088] Since the position of the end head 3 has been determined on the center line to be verified, the position of the end head 3 on the center line to be moved obtained by rotating the center line to be verified is also determined accordingly.

[0089] The end 3 has a preset width, and the width direction refers to the direction intersecting the extension direction of the two sides of the limiter main arm 2 (for example Figure 4c The preset width is determined according to the industrial design data of the end 3. For different design requirements of the stopper, the preset width is different. For example, the preset width can be set to 32mm.

[0090] Regarding step S3, the limiter axis 4 is controlled to move in the reverse direction of the door opening direction on the preset arc, and drives the center line to be moved and the end 3 to move adaptively on the center of the limiter; the preset arc is obtained by rotating the limiter axis 4 with the hinge axis 7 of the door as the center, and the limiter center is the center point corresponding to the limiter body 1 at the preset closed position 11.

[0091] During the reverse motion of the control limiter axis 4 along the preset arc in the direction of door opening, the central angle corresponding to the length of the arc traveled in the reverse motion is the corresponding rotation angle of the hinge axis 7 when the door switches from the closed state to the maximum open state. For example, the central angle is the door opening angle α.

[0092] Regarding step S4, during the adaptive movement process, when the center line to be moved does not exceed the edge area corresponding to the openings on both sides of the limiter body 1, and the end 3 does not exceed the safety gap between the inner panel 5 and the glass panel 6 of the car door, the center line to be verified is determined as the target center line of the limiter main arm 2.

[0093] The edge area can be determined in the following two ways.

[0094]

First method

[0095] When the structures of the stopper are simplified, the method for determining the edge areas corresponding to the openings on both sides of the stopper body 1 includes steps S41 and S42.

[0096] Step S41: When the stopper body 1 is in the preset closed position 11, a first limit line is obtained based on the first end of the opening of the proximal shell surface 101 and the second end of the opening of the distal shell surface 102 of the stopper body 1; and a second limit line is obtained based on the second end of the opening of the proximal shell surface 101 and the first end of the opening of the distal shell surface 102; wherein the first limit line and the second limit line intersect at the center of the stopper;

[0097] Step S42 : determining the space area enclosed by the end of the first limiting line and the end of the second limiting line as the edge area corresponding to the openings on both sides of the limiter body 1 .

[0098] Regarding step S41 , the method for determining the first limit line and the second limit line includes steps S411 and S412 .

[0099] Step S411: When the stopper body 1 is in the preset closed position 11, the positions of the first end and the second end of the opening of the proximal housing surface 101 and the first end and the second end of the opening of the distal housing surface 102 are determined based on the preset gap, the preset manufacturing tolerance, and the preset diameter of the stopper main arm 2;

[0100] Step S412, determining the first limit line according to the position of the first end at the opening of the proximal shell surface 101 and the position of the second end at the opening of the distal shell surface 102; and determining the second limit line according to the position of the second end at the opening of the proximal shell surface 101 and the position of the first end at the opening of the distal shell surface 102.

[0102] in, Figure 5b The CD line segment represents the proximal housing surface 101 when the limiter body 1 is in the preset closed position 11, which is equivalent to Figure 4a The CD line segment in FIG. The EF line segment represents the distal end shell surface 102 when the limiter body 1 is in the preset closed position 11, which is equivalent to Figure 4a Point R represents the center point of the limiter body 1 at the preset closed position 11, segment Q1Q2 represents a segment on the centerline AM1 to be moved, S1 and S2 represent the first and second ends of the opening of the proximal housing surface 101, respectively, and S3 and S4 represent the first and second ends of the opening of the distal housing surface 102, respectively.

[0103] like Figure 5a As shown, when the limiter body 1 is in the preset closed position 11, the positions of the first end S1 and the second end S2 at the opening of the proximal shell surface 101, and the positions of the first end S3 and the second end S4 at the opening of the distal shell surface 102 are determined according to the preset opening distances L1 and L2, the preset manufacturing tolerance Δ and the preset diameter L3 of the limiter main arm 2. The position of each end at the opening of the limiter body 1 also needs to be determined by the straight-line distance from the limiter main arm 2, that is, the straight-line distances LS1, LS2, LS3 and LS4 of S1, S2, S3, and S4 from the limiter main arm 2 are determined respectively. Among them, LS1 and LS2 both need to be less than [(L1-L3) / 2]-Δ; LS3 and LS4 both need to be less than [(L2-L3) / 2]-Δ.

[0104] like Figure 5bAs shown, the first limit line S1S4 is obtained based on the first end S1 of the opening of the proximal shell surface CD and the second end S4 of the opening of the distal shell surface EF; and the second limit line S2S3 is obtained based on the second end S2 of the opening of the proximal shell surface CD and the first end S3 of the opening of the distal shell surface EF. The first limit line S1S4 and the second limit line S2S3 intersect at the center R of the limiter, and the edge area is the area formed by the triangle RS1S2 and the triangle RS3S4.

[0105] [Second method]

[0106] In the case where the structures of the stopper are not simplified, the method for determining the edge areas corresponding to the openings on both sides of the stopper body 1 includes steps S51 to S55.

[0107] Step S51: When the stopper body 1 is in the preset closed position 11, an area enclosed by the first end of the opening of the proximal shell surface 101 of the stopper body close to the stopper axis and the outer surface of the stopper main arm 2 is determined as a first area;

[0108] Step S52, determining the area enclosed by the second end of the opening of the proximal housing surface 101 and the outer surface of the limiter main arm 2 as the second area;

[0109] Step S53, determining the area enclosed by the first end of the opening of the distal shell surface 102 of the stopper body away from the stopper axis and the outer surface of the stopper main arm 2 as the third area;

[0110] Step S54, determining the area enclosed by the second end of the opening of the distal housing surface 102 and the outer surface of the limiter main arm 2 as the fourth area;

[0111] Step S55: determine the first area, the second area, the third area, and the fourth area as edge areas.

[0112] like Figure 5a As shown, the first area is the area enclosed by the first end S1 at the opening of the proximal shell surface 101 and the upper surface of the limiter main arm 2, the second area is the area enclosed by the second end S2 at the opening of the proximal shell surface 101 and the lower surface of the limiter main arm 2, the third area is the area enclosed by the first end S3 at the opening of the distal shell surface 102 and the upper surface of the limiter main arm 2, and the fourth area is the area enclosed by the second end S4 at the opening of the distal shell surface 102 and the lower surface of the limiter main arm 2.

[0113] During the process of adaptively moving the center line to be moved on the center of the limiter, steps S61 and S62 are also included.

[0114] Step S61: When the center line to be moved exceeds the edge areas corresponding to the openings on both sides of the stopper body 1, or the end 3 exceeds the safety gap between the inner plate 5 and the glass panel 6, the preset angle and / or the sample curve function set are adjusted;

[0115] Step S62, based on the adjusted preset angle and / or the adjusted sample curve function set, redetermine the starting center line, the center line to be verified, and the center line to be moved, until the redetermined center line to be moved does not exceed the edge area corresponding to the openings on both sides of the limiter body 1 during the adaptive movement process, and the end 3 does not exceed the safety gap between the inner plate 5 and the glass panel 6.

[0116] The following combination Figure 6a and Figure 6b The provided structural diagram is used to detail the movement process in step S3 and the processes in step S4, step S61 and step S62 in the embodiment of the present application.

[0117] Among them, point A represents the limiter axis 4 before movement, point A1 represents the limiter axis 4 after movement, point B represents the hinge axis 7, line segment IJ represents the inner panel 5 of the car door, line segment GH represents the glass panel 6 of the car door, line segment I 1J1 represents the safety gap line of the inner panel 5, line segment G1 H1 represents the safety gap line of the glass panel 6, line segment OP represents the end 3, point R represents the center point corresponding to the limiter body 1 at the preset closed position 11, line segment S1 S4 represents the first limit line, and line segment S2S3 represents the second limit line.

[0118] After obtaining the center line AM1 to be moved, the control limiter axis A is moved counterclockwise to point A1 on the preset arc. The angle of counterclockwise movement is the door opening α, that is, the angle formed between line segment BA and line segment BA1 is α.

[0119] During the movement of the limiter axis A, the moving center line AM1 moves adaptively, and the end OP also moves adaptively, while the edge area surrounded by the limiter center R, the first limit lines S1 S4 and the second limit lines S2S3 remains fixed, and the safety gap formed by the inner panel safety gap line I1J1 and the glass panel safety gap line G1 H1 remains fixed.

[0120] During the movement process, when the center line to be moved AM1 does not exceed the edge area enclosed by the first limit line S1 S4 and the second limit line S2S3 and the end OP does not exceed the safety gap formed by the inner panel safety gap line I1J1 and the glass panel safety gap line G1 H1, the center line to be moved AM1 is determined as the target center line of the limiter main arm.

[0121] During the movement process, if the center line to be moved AM1 exceeds the edge area enclosed by the first limit lines S1-S4 and the second limit lines S2-S3, or the end OP exceeds the safety gap formed by the inner panel safety gap line I1J1 and the glass panel safety gap line G1-H1, the preset angle in step S12 and / or the sample curve function set in step S14 are adjusted to re-determine the starting center line AL, the center line to be verified AM, and the center line to be moved AM1. Exemplarily, the compensation angle δ in step S12 is adjusted to adjust the preset angle, and / or the preset curvature of the sample curve function set in step S14 is adjusted.

[0122] In summary, the embodiment of the present application determines the center line to be verified between the limiter axis 4 and the end 3 of the limiter at the preset maximum opening position 12 according to the preset closing position 11 and the preset maximum opening position 12 corresponding to the limiter body 1 of the limiter and the sample curve function set; the preset closing position 11 is the position corresponding to the limiter body 1 in the closed state of the vehicle door, and the preset maximum opening position 12 is the position corresponding to the limiter body 1 in the maximum open state of the vehicle door; the center line to be verified is controlled to rotate around the limiter axis 4 from the maximum open state of the vehicle door to the closed state of the vehicle door, and the center line to be moved is obtained. ; Control the limiter axis 4 to move in the reverse direction of the door opening direction on the preset arc, and drive the center line to be moved and the end head 3 to move adaptively on the center of the limiter; the preset arc is obtained by rotating the limiter axis 4 with the hinge axis 7 of the door as the center, and the limiter center is the center point corresponding to the limiter body 1 in the preset closed position 11; in the adaptive movement process, when the center line to be moved does not exceed the edge area corresponding to the openings on both sides of the limiter body 1, and the end head 3 does not exceed the safety gap between the inner panel 5 and the glass panel 6 of the door, the center line to be verified is determined as the target center line of the limiter main arm 2. It can be seen that the embodiment of the present application determines the center line to be verified through the preset closing position 11 and the preset maximum opening position 12 of the limiter, combined with the sample curve function set, and verifies whether the center line to be moved meets the design requirements during the adaptive movement process, thereby quickly determining the center line of the limiter main arm 2, reducing the workload of the design process, and reducing the requirements for computing power.
