At this time, the front door has been dismantled and transferred to the door sub-assembly line according to the process flow. The adjustment reference for the flushness is missing, and the assembly effect is poor. The traditional solution is to ensure this through simulation tooling. When there is a tolerance between the hinge axis and the door size of the door outer panel, the positioning accuracy will decrease. The flushness problem can only be discovered after the front wheel fender, tire, and front door are assembled. At this time, the fender has been fixed with screws, and the flushness between the fender and the door cannot be adjusted.

DETAILED DESCRIPTION

[0047] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0048] Reference Figure 1As shown, the present application provides a flush adjustment device 1, which is located between the vehicle body 110, the fender 70 and the fender beautification plate 100, and on one side of the door hinge 80. An adjustment hole 90 for adjusting the flush adjustment device is reserved on the fender beautification plate 100. Through the adjustment hole 90, the fender 70 can be adjusted in a direction close to or away from the vehicle body 110, thereby adjusting the flushness of the fender 70. Figure 2-Figure 8 It can be seen that the flushness adjustment device 1 includes:

[0049] The adjusting component 10 is fixed on the vehicle body 110, and has a first channel 101 and a second channel 102, wherein the axis of the first channel 101, i.e., the X direction, is parallel to the plane of the vehicle body 110, and the axis of the second channel 102, i.e., the Y direction, is perpendicular to the plane of the vehicle body 110, and the first channel 101 and the second channel 102 are partially overlapped, i.e., a "cross" state is formed between the first channel 101 and the second channel 102; the first adjusting device can be slidably arranged in the first channel 101; the adjusting seat 40 can be slidably arranged in the second channel 102, and the end of the adjusting seat 40 away from the vehicle body 110 is fixedly connected to the fender 70; a driving connection structure is arranged between the first adjusting device and the adjusting seat 40, and the driving connection structure can make the first adjusting device reciprocate along the axis direction of the first channel, i.e., the X direction (hereinafter, the axis direction of the first channel is equal to the X direction), and drive the adjusting seat 40 to reciprocate along the Y direction. The first adjusting device may be an integral sliding structure arranged in the first channel 101, and the first adjusting device may be directly acted on to slide in the first channel 101, thereby driving the adjusting seat 40 to reciprocate in the second channel, thereby realizing movement of the fender in the axial direction of the second channel, that is, the Y direction in the accompanying drawings (the axial direction of the second channel is equivalent to the Y direction hereinafter), so as to adjust the aberration.

[0050] Further, in the flush adjustment device provided in the present application, the first adjustment device includes: a slider 20, which is slidably disposed in the first channel 101; and a screw 50 is threadedly connected to the adjustment component 10, and one end of the screw 50 is connected to the slider 20 to drive the slider 20 to reciprocate along the first channel 101. At the same time, the end of the screw 50 away from the slider 20 is aligned with the adjustment hole 90 on the fender beautification plate, so that the adjustment tool can be connected to the screw 50 through the adjustment hole 90 of the fender beautification plate to rotate the screw 50 and move the screw 50. Since the screw 50 is connected to the slider 20, the screw 50 can drive the slider 20 to move left and right along the X direction in the first channel 101 when it moves left and right in the X direction. There is a driving connection structure 30 between the slider 20 and the adjustment seat 40, and the driving connection structure 30 is used to drive the adjustment seat 40 to slide in the second channel 102 when the slider 20 reciprocates along the first channel 101. Specifically, when the slider 20 moves to the left in the first channel 101, the driving connection structure 30 drives the adjustment seat 40 to move away from the vehicle body 110 along the Y direction or move toward the vehicle body 110 along the Y direction; when the slider 20 moves to the right in the first channel 101, the adjustment seat 40 moves toward the vehicle body 110 along the Y direction or moves away from the vehicle body 110 along the Y direction. The movement of the adjustment seat 40 drives the fender fixed on the adjustment seat 40 to move toward or away from the vehicle body 110.

[0051] Furthermore, in the flushness adjustment device 1 provided in the present application, the driving connection structure 30 includes:

[0052] A slide groove 31, which is disposed on the adjustment seat 40 and is inclined relative to a straight line where the sliding direction of the slider 20 in the first channel is located;

[0053] A pin 32, one end of which is slidably disposed in the slide groove 31, and the other end of which is fixedly connected to the slider 20;

[0054] When the slide groove 31 moves relative to the first channel 101, the pin shaft 32 is driven to move in the second channel 102;

[0055] The pin shaft 32 is perpendicular to a plane formed by the axis of the first channel 101 and the axis of the second channel 102 .

[0056] Specifically, the slide groove 31 is provided on the adjustment seat 40, and may or may not penetrate the adjustment seat 40. One end of the pin shaft 32 is slidably provided in the slide groove 31, and the other end of the pin shaft 32 is fixed in the slider 20. Since the slide groove 31 is provided for the purpose of causing the adjustment seat 40 to be displaced in the Y direction during the movement of the pin shaft 32 along the X direction, there is a certain angle between the setting direction of the slide groove 31 and the direction of the straight line where the sliding direction of the slider 20 in the first channel 101 is located, and the size of the angle depends on the need to move the adjustment seat 40 in the Y direction at a desired speed. The slide groove 31 is arranged on the adjustment seat in such a manner that its extension direction is perpendicular to the plane formed by the X direction and the Y direction. In other words, the plane where the orthographic projection of the slide groove 31 is located is parallel to the plane formed by the X direction and the Y direction. At the same time, the pin shaft 32 is arranged in such a manner that it is perpendicular to the plane formed by the X direction and the Y direction. That is, when the pin shaft 32 slides relatively in the slide groove 31, the second channel 102 blocks the adjustment seat 40, so that the adjustment seat 40 moves in the Y direction. Figure 2 Taking the four quadrants formed by the two intersecting lines of the X direction and the Y direction as an example, when the inclined direction of the slide slot 31 passes through the second and fourth quadrants, when the slider 20 moves to the left, the mounting seat 40 moves away from the vehicle body 110; when the slider 20 moves to the right, the mounting seat 40 moves toward the vehicle body 110. When the inclined direction of the slide slot 31 passes through the first and third quadrants, when the slider 20 moves to the left, the mounting seat 40 moves toward the vehicle body 110; when the slider 20 moves to the right, the mounting seat 40 moves away from the vehicle body 110.

[0057] Similarly, further, in the face difference adjustment device 1 provided in the present application, the driving connection structure 30 includes a slide groove 31 which is arranged on the slider 20 and is inclined relative to the straight line where the sliding direction of the slider 20 in the first channel is located; and a pin shaft 32, one end of the pin shaft 32 can be slidably arranged in the slide groove 31, and the other end of the pin shaft 32 is fixedly connected to the adjustment seat 40; wherein, the slide groove 31 enables the pin shaft 32 to move in the second channel 102 when the slide groove 31 moves relative to the first channel 101; the pin shaft 32 is perpendicular to the plane formed by the axis of the first channel 101 and the axis of the second channel 102.

[0058] Specifically, the arrangement of the slide groove 31 and the pin 32 in the driving connection structure 30 in this embodiment is similar to that in Figure 2 , Figure 4-Figure 5 The difference of the structure shown is that the slide groove 31 is arranged on the slider 20 instead of the adjustment seat 40, and the pin 32 is fixed to the adjustment seat 40.

[0059] In the present application, the method for fixing the pin 32 and the slider 20 or the adjustment seat 40 is not limited, and the specific fixing method depends on the shape or structure of the connecting part between the pin 32 and the slider 20 or the adjustment seat 40.

[0060] Furthermore, in the flushness adjustment device 1 provided in the present application, a third channel 103 parallel to the first channel 101 is opened in the middle of the slider 20, and the third channel 103 is used to accommodate all or part of the adjustment seat 40;

[0061] Alternatively, a fourth channel 104 parallel to the second channel 102 is opened in the middle of the adjustment seat 40 , and the fourth channel 104 is used to accommodate all or part of the slider 20 .

[0062] Specifically, Figure 4 and Figure 5 The components of a flushness adjustment device 1 are shown, wherein the adjustment component 10 is a cubic block, and the left side of the adjustment component 10 is provided with a first channel 101 (not shown in the figure) and a second channel 102 in the shape of a "cross", wherein the slider 20 is a cube as a whole and can be slidably arranged in the first channel 101, and the slider 20 is provided with a third channel 103 matched with the second channel 102 of the adjustment component 10 on the surface corresponding to the slider 20 and the second channel 102, and the width of the third channel 103 in the X direction is greater than the width of the adjustment seat 40 in the X direction. Similarly, since the adjustment seat 40 is slidably arranged in the second channel 102 of the slider 20, that is, the width of the channel 103 is greater than the width of the second channel 102 in the X direction.

[0063] Figure 6 The components of the flush adjustment device 1 shown may also include an adjustment seat 40 in the form of a cubic block, in which the slider 20 is slidably disposed. A fourth channel 104 is provided on the surface of the adjustment seat 40 corresponding to the first channel 101 of the adjustment component 10, and the width of the fourth channel 104 in the Y direction is greater than the width of the slider 20 in the Y direction. Similarly, since the slider 20 is slidably disposed in the first channel 101 of the adjustment seat 40, the width of the fourth channel 104 is greater than the width of the first channel 101 in the Y direction.

[0064] Furthermore, in the flushness adjustment device 1 provided in the present application, a disc 51 or a ball head 52 is provided at one end of the screw rod 50 , and a receiving portion for receiving the disc 51 or the ball head 52 is provided on the slider 20 .

[0065] Specifically, refer to Figure 6-Figure 9It can be seen that the connection between the screw rod 50 and the slider 20 is that a disk 51 or a ball head 52 with a larger diameter is provided at the end of the screw rod 50, and a connecting portion 54 with a smaller diameter exists between the disk 52 or the ball head 52 and the rod portion 53 of the screw rod 50. A receiving portion 21 for receiving the disk 51 or the ball head 52 is provided on the right side of the slider 20, and an opening 22 for allowing the connecting portion 54 of the screw rod 50 to pass through is provided at the end of the receiving portion, so as to complete the assembly of the screw rod 50 and the slider 20. At the same time, a threaded hole for receiving the screw rod 50 is provided on the right side of the adjustment component 10. A circular opening is provided on the far right side of the adjustment component 10, so as to allow a tool to extend into and contact the screw rod 50 to rotate the screw rod 50.

[0066] Further, refer to Figure 2-Figure 3 As shown, in the flush adjustment device 1 provided in the present application, an adjustment groove 55 is provided on one end of the screw rod 50 away from the adjustment seat 40 , for cooperating with an adjustment tool to realize the rotation of the screw rod 50 .

[0067] Further, refer to Figure 4-Figure 8 As shown, in the flushness adjustment device 1 provided in the present application, the adjustment groove 55 is a hexagonal hole.

[0068] Further, refer to Figure 2-Figure 5 As shown, in the flush adjustment device 1 provided in the present application, a clamping structure is provided at one end of the screw 50 away from the adjustment seat 40, for clamping the screw 50. The purpose of providing the clamping structure is to clamp the screw 50 to prevent the screw 50 from accidentally rotating, thereby changing the flush that has been adjusted.

[0069] Furthermore, in the flush adjustment device 1 provided in the present application, the clamping structure is a clamping cover with external threads, which is threadedly connected to the adjustment component 10. After the clamping cover is rotated, it is used to abut the end of the screw 50 away from the adjustment seat.

[0070] Furthermore, combined with Figure 3-Figure 5 As shown, in the face difference adjustment device 1 provided in the present application, the clamping structure is a clamping nut 60 with an external thread, the clamping nut 60 is threadedly connected to the adjustment component 10, and the clamping nut 60 has an inward step 61 for abutting the end of the screw 50 away from the adjustment seat; the clamping nut also has a boss 62, and the boss 62 cooperates with a tool to rotate the clamping nut.

[0071] Specifically, the adjusting component 10 is provided with a receiving groove for accommodating the top of the screw rod 50, and a thread matching the external thread of the clamping nut is provided on the inner surface of the receiving groove, so that the clamping nut can move along the thread of the inner surface of the receiving groove. The clamping nut has an inward step 61 for contacting the top of the screw rod 50 for clamping the screw rod 50. At the same time, the opening of the clamping nut allows a tool to extend into the adjustment groove of the screw rod 50 to adjust the screw rod 50. A boss 62 is provided on the end surface of the clamping nut, such as an external hexagonal boss 62, which is used for the tool to clamp the clamping nut and rotate it, so that the step 61 of the clamping nut can clamp the screw rod 50.

[0072] The following describes how to adjust the flushness of the fender 70 and tighten the adjusting screw 50 in combination with the above-mentioned embodiment.

[0073] First check whether the surface difference of the fender meets the requirements. If not, adjust the surface difference.

[0074] The specific structure of the clamping structure is observed through the adjustment hole 90 of the fender beautification plate 100, and the clamping structure is removed in a manner corresponding to the structure. For example, when the clamping structure is a snap-on structure, the clamping structure can be removed in parallel. If the clamping structure is a nut structure, the clamping structure can be removed by rotating it.

[0075] After removing the clamping structure, a tool corresponding to the end adjustment groove 55 of the screw 50 is used to rotate the screw, so that the screw 50 moves and then drives the slider 20 to move. When the slider 20 moves, due to the action of the driving structure 30, the adjustment seat 40 moves in the Y direction, thereby adjusting the fender 70, and measuring the surface difference of the adjusted fender 70 until the surface difference meets the requirements.

[0076] After the flushness meets the requirement, the pressing structure is installed on the adjustment component 10 to press the screw 50. The flushness adjustment of the entire fender 70 is completed.

[0077] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
