[0053] It should be understood by those skilled in the art that these embodiments are merely used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art may make adjustments as needed to adapt to specific applications.

[0055] It should be noted that, in the description of the present invention, although the various steps of the control method of the present invention are described in this application in a specific order, such order is not restrictive. Without departing from the basic principles of the present invention, those skilled in the art may perform the steps in a different order. In addition, the terms "first," "second," "third," "fourth," "fifth," "sixth," and "seventh" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance.

[0056] Based on the problem pointed out in the background technology that the existing hinge arrangement consumes a lot of time and reduces the efficiency of vehicle development, the present invention provides a method for arranging automobile tailgate hinges, which aims to save time in hinge arrangement position, improve work efficiency, and thus enhance the efficiency of vehicle development.

[0057] It should be noted that the inventors have conducted in-depth research on the impact of the automobile tailgate hinge arrangement on the efficiency of vehicle development. When exploring the impact of the automobile tailgate hinge arrangement on the efficiency of vehicle development, they also compared the existing hinge arrangement methods. The automobile tailgate hinge arrangement method of the present invention can shorten the hinge arrangement time, thereby improving the hinge arrangement efficiency and thus improving the vehicle development efficiency.

[0058] See attached Figure 1 , Figure 1 FIG. 1 is a flow chart of a method for arranging a hinge for a car tailgate according to an embodiment of the present invention. Figure 1As shown, the automobile tailgate hinge arrangement method in the embodiment of the present invention mainly includes the following steps:

[0059] Step S1: Obtain the hinge fastening direction, the gap image between the top cover and the tailgate, the rear view limit line, the tailgate opening height limit line, and the limit boundary parameters of the top cover and the tailgate;

[0060] Step S2: Determine the position of the hinge's rotation axis based on the hinge fastening direction, the gap between the top cover and the tailgate, the rear view limit line, the tailgate opening height limit line, and the limit boundary parameters of the top cover and the tailgate to determine the hinge position.

[0061] The present invention first obtains the direction in which the hinge is fastened, the image of the gap between the top cover and the tailgate, the limiting line of the rear view, the limiting line of the tailgate opening height, and the limiting boundary parameters of the top cover and the tailgate, and then determines the center position of the hinge's rotating shaft based on the direction in which the hinge is fastened, the image of the gap between the top cover and the tailgate, the limiting line of the rear view, the limiting line of the tailgate opening height, and the limiting boundary parameters of the top cover and the tailgate, so as to determine the position of the hinge. In this way, there is no need to repeatedly iterate the movement relationship between the tailgate and the surrounding area, the human-machine opening height, the dimensional tolerance, and the assembly method after determining the position of the hinge, thereby saving design time, improving work efficiency, and thus improving the efficiency of vehicle development.

[0062] In one embodiment, in step S1, the fastening direction of the hinge is at least one of the X, Y, and Z directions; and / or, the gap between the top cover and the tailgate is in the shape of at least one of a positive C, a negative C, and a straight line; and / or, the type of hinge is a hinge hinge, a gooseneck hinge, and a connecting rod hinge, the limit lines of the rear view are A123-2-U and A124-2-U, the limit line of the tailgate opening height is H110, and the limit boundary parameters of the top cover and the tailgate are determined based on the structural dimensions of the tailgate and the top cover collected at different temperatures.

[0063] In one embodiment, the method further includes: determining the type of hinge based on the gap image between the top cover and the tailgate, and step S2 specifically includes: determining the center position of the hinge's rotation axis based on the fastening direction of the hinge, the type of hinge, the limit line of the rear view, the limit line of the tailgate opening height, and the limit boundary parameters of the top cover and the tailgate to determine the position of the hinge.

[0064] In this embodiment, the design's intended seam separation is first understood, followed by the determination of the X, Y, and Z directions for hinge fastening, which are then incorporated into the overall layout. Hinge types are selected based on the gap's shape. For example, if the gap between the top cover and tailgate forms a positive C, a hinge-type hinge is selected; if it forms an inverted C, a gooseneck hinge is selected; if it forms an inverted straight line, both a hinge and a gooseneck hinge are selected. Link hinges can be used regardless of whether the gap forms a positive C, a negative C, or a straight line. The hinge types selected based on the above gap shapes are not exclusive and are provided for illustrative purposes only, without limitation. The hinge data, determined based on the gap between the roof and tailgate, was imported into the master layout. Based on ergonomics, rear visibility, and tailgate opening height requirements, the rear visibility constraints were converted to A123-2-U and A124-2-U, and the tailgate opening height constraint was H110. These were also imported into the master layout. Simultaneously, the tailgate and roof structural dimensions at room temperature, as well as those after thermal deformation, were collected and imported into the master layout to facilitate subsequent hinge position determination. Furthermore, the roof and tailgate dimensions in hot weather tend to be slightly larger than at room temperature, a factor also considered during the design process.

[0065] Among them, according to SAE J1100 (automotive dimension standard), A123-2-U is made, which is the upper rear field of view requirement of the center of the vehicle based on ergonomic input; A1234-2-U is the upper rear field of view requirement of the driver's position based on ergonomic input; H110 is the trunk opening height requirement based on ergonomic input and other restriction limits.

[0066] See also Figure 3 and Figure 4 , Figure 3 FIG. 1 is a structural diagram of a method for arranging hinges for a car tailgate according to an embodiment of the present invention. Figure 4 yes Figure 3Partially enlarged view in the middle. In one embodiment, step S2 further includes determining the relative relationship parameter L1 between the direction of hinge fastening and the axis of the hinge according to the direction of hinge fastening, the type of hinge and the limit line of the rear view. The limit parameter L2 is formed according to the limit line of the tailgate opening height, the limit boundary parameters of the top cover and the tailgate. The axis installation and debugging parameter L3 of the hinge is set according to the type of hinge, and the relative relationship parameter L1 is continuously iterated and combined with the limit parameter L2 and the axis installation and debugging parameter L3 to derive the center position of the hinge rotation axis to determine the position of the hinge, and then determine the optimal position of the hinge. Wherein, as further described below, L1 is the radius of the circle tangent to the first concentric circle and the second concentric circle; L2 includes: the gap surface difference between the top cover and the tailgate and its tolerance, the thermal expansion coefficient, the safety gap, the structural space; L3 is the tolerance of the hinge installation.

[0067] See also Figure 3 and Figure 4 In one specific embodiment, at the seam between the top cover and the tailgate, a first concentric circle with a radius equal to the side fillet radius plus a safety gap is formed with the center of the top cover's side fillet. At the seam between the top cover and the tailgate, a rectangle is formed with the center of the tailgate's side fillet. The upper parallel sides of the rectangle are parallel to the tangent line of the tailgate's side molding surface, forming parallel sides. The length of the parallel sides is equal to the thermal expansion coefficient tolerance of the gap between the top cover and the tailgate, and the length of one vertical side of the rectangle is equal to the thermal expansion coefficient tolerance of the face difference between the top cover and the tailgate. A second concentric circle with the same radius as the tailgate's side fillet is formed at the vertex opposite the center of the tailgate's side fillet. Circles tangent to the first and second concentric circles are formed, with the center of the tangent circles being the center of the hinge's rotation axis. This allows for accurate hinge position determination, eliminating the need for later adjustments to related components and saving process steps.

[0068] See Figure 2 , Figure 2 Flowchart of another embodiment of a hinge arrangement method for a car tailgate according to the present invention. In one embodiment, the hinge arrangement method of the present application further comprises: Step S3: verifying the position of the hinge in reverse according to the arrangement of upstream components.

[0069] In this embodiment, the step of "verifying the arrangement of upstream components to reversely confirm the position of the hinge" specifically includes: determining the arrangement position of the tailgate lock and the lock catch according to the position of the hinge, and verifying the arrangement position of the tailgate lock and the lock catch to reversely confirm the position of the hinge. By confirming the arrangement position of the tailgate lock and the lock catch after determining the position of the hinge, the position of the hinge can be verified for reverse confirmation, thereby avoiding deviation in the position of the hinge, and arranging the tailgate lock and the lock catch is convenient.

[0070] In this embodiment, the step of "verifying the arrangement of upstream components to reversely confirm the position of the hinge" specifically includes: determining the arrangement position of the tailgate bumper based on the position of the hinge, and verifying the arrangement position of the bumper to reversely confirm the position of the hinge. By verifying the arrangement position of the tailgate bumper after determining the position of the hinge, the hinge position can be verified for reverse confirmation, thereby preventing deviation in the hinge position and facilitating the arrangement of the tailgate bumper.

[0071] In this embodiment, the step of "verifying the hinge position based on the arrangement of upstream components" specifically includes determining the arrangement positions of the tailgate stop and sealing strip based on the position of the hinge, and verifying the arrangement positions of the tailgate stop and sealing strip to verify the hinge position. By verifying the arrangement positions of the tailgate stop and sealing strip after determining the hinge position, the hinge position can be verified to verify the hinge position, thereby preventing deviation in the hinge position and facilitating the arrangement of the tailgate stop and sealing strip.

[0072] In this embodiment, the step of "verifying the hinge position based on the arrangement of upstream components" specifically includes determining the tailgate lever's arrangement position based on the hinge's position, and verifying the tailgate lever's arrangement position to verify the hinge's position. By verifying the tailgate lever's arrangement position after determining the hinge's position, the hinge's position can be verified to verify the hinge's position, preventing deviations in the hinge's position and facilitating tailgate lever arrangement.
