Technical Field

[0002] A door limiter is a device installed on a car door to restrict the opening angle and position of the door. To ensure smooth and quiet opening and closing, the limiter's main arm must slide within its housing without any clearance or interference. This means that during door opening, the center line of the limiter's main arm contour must pass through the engagement point and remain perpendicular to the limiter housing. Since the limiter needs to rotate around both its rotation axis and the door hinge's rotation axis, the center line of the door limiter's main arm contour must be specifically designed according to the door's design requirements.

[0107] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0108] Figure 1 A flowchart illustrating an embodiment of a method for designing the centerline of the main arm contour of a door limiter according to the present invention is shown. This method is performed by a device for designing the centerline of the main arm contour of a door limiter. Figure 1 As shown, the design of the main arm contour centerline of the door limiter includes the following steps:

[0109] Step 110: Obtain the door limiter rotation point A, the door rotation point B, and the limiter box engagement point C0.

[0110] The door limiter rotation point A is determined by the structure of the door limiter K. In actual application, the door rotation point B and the limiter box engagement point C0 can be set or adjusted by the designer according to the door design, based on the door limiter rotation point A.

[0111] like Figure 2 As shown, the door rotation point B is a point on the rotation axis (door hinge axis) of the door opening and closing. In this embodiment, the door rotation point B and the limiter box engagement point C0 are determined by the following method: A reference plane F is drawn through the rotation point A of the door limiter K and perpendicular to the door hinge axis H. The door rotation point B is then the intersection of the reference plane F and the door hinge axis H. Furthermore, the center of the limiting feature of the door limiter is taken as the limiter box engagement point C0 on the reference plane F.

[0112] Step 120: Based on the door rotation point B and the limiter box engagement point C0, obtain the trajectory points C1 to C2 of the limiter box engagement point C0. N Where N is a natural number, and the trajectory points C1 to C2 are... N The distance from each trajectory point to the door rotation point B is equal.

[0113] For details, see Figure 3The trajectory points C1 to C2 can be determined using the following method. N Rotate the engagement point C0 of the limit switch box around the door rotation point B by an angle β to obtain the trajectory point C1. Then rotate the trajectory point C1 around the door rotation point B by an angle β to obtain the trajectory point C. 23 This process is repeated N times to obtain the trajectory point C. N Generally, N is around 7 to 10, with no upper limit. Here, (N) × β represents the maximum opening angle of the car door (68°), and the turning angle β(∠C) N-1 BC N The angle is 7° to 10°.

[0114] Step 130: Based on the engagement point C0 of the limiter box and the preset angle, determine the inner contour point D0 and the outer contour point E0, where ∠BC0D0 is the preset angle, and the distance from the door limiter rotation point A to the outer contour point E1 is less than the distance from the door limiter rotation point A to the trajectory point C1.

[0115] Wherein, the engagement point C0 of the limiter box is the center point of the line connecting the inner contour point D0 and the outer contour point E0. In addition, the distance from the door limiter rotation point A to the outer contour point E0 is less than the distance from the door limiter rotation point A to the trajectory point C1, so that the trajectory point C1 is located outside the arc of the arc E1D1, and the arc E1D1 is an arc with the door limiter rotation point A as the center. Figure 4 The median angle α is the preset angle, which is 0° to 180°, including 0° and 180°.

[0116] Step 140: Based on the door limiter rotation point A, inner contour point D0, outer contour point E0, and the preset angle, determine the inner contour points D2 to D1 in sequence. N and outer contour points E2~E N , where ∠BC N D N For the preset angle, the inner contour point D M The distance to the rotation point A of the door limiter is equal to the distance to the outer contour point E. M-1 The distance to the door limiter rotation point A, and the inner contour point D M To trajectory point C M The distance is equal to the distance from the outer contour point E. M To trajectory point C M The distance, M, is a natural number less than or equal to N.

[0117] Among them, in determining the inner contour points D2~D N and outer contour points E2~E N During the process, first pass through the outer contour point E M-1Draw a circle M with the rotation point A of the door limiter as the center, and determine the inner contour point D on the circle M. M And ∠BC M D M =∠BC0D0; then, based on the trajectory point C M and inner contour point D M Determine the outer contour point E M Among them, trajectory point C M For the inner contour point D M and the outer contour point E M The center point of the line.

[0118] Specifically, such as Figure 4 As shown, a circle 0 is drawn with the rotation point A of the door limiter as the center, passing through the outer contour point E0, and ∠BC1D1=∠BC0D0. The inner contour point D1 is determined on the circle 1. Then, based on the trajectory point C1 and the inner contour point D1, the outer contour point E1 is determined. The trajectory point C1 is the center point of the line connecting the inner contour point D1 and the outer contour point E1.

[0119] Similarly, using the above method, draw circles 1 to N in sequence to determine inner contour point D2, outer contour point E2, inner contour point D3, outer contour point E3, ..., inner contour point D N-1 Outer contour point E N-1 Inner contour point D N and outer contour point E N .

[0120] Step 150: Based on the inner contour points D0~D N The outer contour points E0 to E N The door limiter rotation point A, the positioner box engagement point C0, and the trajectory points C1 to C2 are mentioned. N Determine the center line of the main arm contour of the door limiter.

[0121] Specifically, in determining the center line of the main arm contour of the door limiter, firstly, all contour lines D are sequentially... N E N Rotate around the door limiter rotation point A, so that the inner contour point D... N With outer contour point E N-1 Overlap, generating contour line P; then, through the limiter box engagement point C0 and trajectory points C1~C in the contour line P. N With outline D N E N To create a tangent, a spline curve is created. Finally, the rotation point A of the door limiter is connected to the engagement point C0 of the door limiter box, and extended to be tangent to the spline curve to generate the center line of the main arm profile of the door limiter.

[0122] It should be noted that in practical applications, contour lines D1E1 to D are sequentially connected. N E N Rotate around point A of the door limiter, so that point D... N With point E N-1 When the contour line P is generated by overlapping, such as Figure 5 As shown, it can be followed from contour line D0E0 to contour line D N E N In this sequence, each contour line is rotated individually to a predetermined position; or, as... Figure 6 As shown, it can be followed according to the outline D N E N Following the sequence from contour line D0E0, multiple contour lines are sequentially combined and then rotated to a predetermined position. For example, first, contour line D... N E N Rotate to outline D N-1 E N-1 The position, then the outline D N E N and outline D N-1 E N-1 After assembling into a whole, rotate to outline D. N-2 E N-2 Using this method, the final contour line from D1E1 to D is obtained. N E N Combined to form the outline P.

[0123] After obtaining the contour line P, as follows Figure 7 As shown, the limiter box engagement point C0 and trajectory points C1 to C2 in the contour line P are... N With outline D N E N Create a spline curve S to represent the tangent.

[0124] It should be noted that, as Figure 7 As shown, based on the inner contour points D0 to D... N The outer contour points E0 to E N The door limiter rotation point A, the limiter box engagement point C1, and the trajectory points C1 to C2 are mentioned. N The process of determining the center line of the main arm contour of the door limiter also includes connecting the rotation point A of the door limiter and the engagement point C1 of the limiter box, and creating a spline curve T that is tangent to the spline curve S. Additionally, a straight line segment G is created through the end point of the spline curve S and is tangent to the spline curve S. The length of the straight line segment G needs to be determined according to the limiter box limit structure dimensions.

[0125] It should be noted that the line connecting the inner contour point D0 and the outer contour point E1 is the contour line D0E0. In practical applications, various main arm contour centerline schemes can be output by adjusting the contour line D0E0 and / or the preset angle. In particular, by adding the preset angle as a variable, the main arm of the door limiter can adapt to the spatial arrangement requirements of different doors by adjusting the main arm contour centerline.

[0126] It should be noted that the outline D1E1 to the outline D N E N The lengths of all contour points are determined by the length of the contour line D0E0 and the preset angle. In practical applications, by adjusting the length of the contour line D0E0 and the preset angle, the lengths of all contour lines are made relatively uniform, i.e., the inner contour point D... N-1 and the outer contour point E N-1 Connect D N-1 E N-1 The length of the inner contour point D N and the outer contour point E N Connect D N E N The difference in length is less than or equal to a preset threshold.

[0127] If the connection D N-1 E N-1 The length of the connecting line D N E N If the length difference is greater than the preset threshold, which is visually manifested as a significantly uneven change in the radius from circle 0 to circle N, then the length of the line D0E0 connecting the inner contour point D0 and the outer contour point E0 is adjusted until the length of the line D0E0 is equal to the preset threshold. N-1 E N-1 The length of the connecting line D N E N The length difference is less than or equal to the preset threshold.

[0128] This invention provides a method for designing the centerline of the main arm contour of a door limiter. First, the rotation point A of the door limiter, the door rotation point B, and the limiter box engagement point C0 are obtained. Then, based on the door rotation point B and the limiter box engagement point C0, trajectory points C1 to C2 of the limiter box engagement point C0 are generated. N Then, using the engagement point C0 of the limiter box and the trajectory points C1 to C2 respectively... N Centered on the engagement point C0 of the limiter box, the rotation point A of the door limiter, and a preset angle, the inner contour points D1 to D2 are determined sequentially. N and outer contour points E1~E N Finally, based on the inner contour points D1 to D... NThe outer contour points E1 to E N The door limiter rotation point A, the positioner box engagement point C0, and the trajectory points C1 to C2 are mentioned. N Determine the center line of the main arm contour of the door limiter.

[0129] This invention provides a method for designing the centerline of the main arm contour of a door limiter. By adding a preset angle as a variable, multiple main arm contour centerline schemes can be output, allowing the main arm of the door limiter to adapt to the spatial arrangement requirements of different doors. Furthermore, by adjusting the length of the contour line D0E0, setting a suitable preset angle, and using spline curve fitting to the centerline of the main arm contour of the door limiter, fewer trajectory points can be used while ensuring the accuracy of the main arm contour centerline. This simplifies the design process of the main arm contour centerline of the door limiter and improves its design efficiency.
