[0037] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present application.

[0038] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the scope of this application and its application or use.

[0039] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0040] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0041] This application provides a method and system for assembling a hood hinge, which changes the mounting surface of the hood hinge to the vehicle body from Z-axis to Y-axis, and uses an auxiliary device to associate the hood with the side panel in the Z-axis direction, shortening the dimensional chain link, thereby improving the DTS (Dimension Technical Specification) compliance rate of the hood and side panel. Furthermore, this method can achieve the positioning of the hood hinge independently on both sides, and has strong versatility.

[0042] like Figure 5 As shown in this application, the cover hinge 4 includes an upper hinge blade 42 and a lower hinge blade 41, which are hinged together by a hinge shaft 44. The lower hinge blade 41 has two connecting holes at its lower part and is fixed to the side panel in the Y direction by a first connecting bolt 5. The lower hinge blade 41 has two positioning holes in its middle part. This application mainly solves the problem of assembly accuracy of the lower hinge blade 41.

[0043] like Figure 6 As shown, the hood hinge assembly system provided in this application includes a side panel 100, a side beam 200, a front module 300, and an auxiliary device. Different parts of the auxiliary device are detachably connected to the side panel 100, the side beam 200, and the front module 300. The auxiliary device establishes a local reference in the matching area between the hood and the side panel, shortens the dimensional links, and improves the assembly accuracy.

[0044] like Figure 6 and 7As shown, the auxiliary device includes a body 17, with a main positioning pin 1 and an auxiliary positioning pin 2 fixed at both ends of the body 17, and multiple clamping parts spaced apart in the middle of the body 17. Two hair cap hinge positioning pins 3 are movably connected to the body 17.

[0045] As one embodiment, one or more of the main positioning pin 1, auxiliary positioning pin 2, clamping member and cap hinge positioning pin 3 are detachably connected to the body 17 via a connecting block.

[0046] As an example, the connecting block is connected to the body 17, to the connecting blocks, and to the main positioning pin 1, auxiliary positioning pin 2, clamping member, or cap hinge positioning pin 3 by bolts.

[0047] As another embodiment, such as Figure 8 As shown, taking the connecting block 14 as an example, the connecting part of the connecting block 14 includes a bolt hole 15 and pin holes 16 symmetrically arranged on both sides of the bolt hole 15. The two connecting parts are positioned and connected to each other by a bolt and the positioning pins on both sides.

[0048] As one embodiment, each clamping component includes an L-shaped connecting block and a quick clamp detachably connected to the body 17 of the auxiliary device. A first side of the L-shaped connecting block is detachably connected to the body, and the end of the second side of the L-shaped connecting block faces the clamp head of the quick clamp. The side beam 200 clamps between the end of the second side and the clamp head. During clamping, the L-shaped connecting block is first placed against the side beam 200, and then the position of the quick clamp is adjusted so that the two clamp the side beam. Locking the quick clamp then completes the clamping process.

[0049] As an example, such as Figure 6 and 7 As shown, the auxiliary device is equipped with three clamping components. The first clamping component includes an L-shaped connecting block 8 and a quick clamp 9. The first side of the L-shaped connecting block 8 is detachably connected to the main body 17, and the end of the second side of the L-shaped connecting block 8 faces the clamp head of the quick clamp 7. The first clamping component clamps the portion 201 of the side beam 200 near the front end module 300. The second clamping component includes the L-shaped connecting block 8 and the quick clamp 7. The second clamping component clamps the portion 202 of the side beam 200 near the mounting position 101 of the main positioning pin 1. The third clamping component includes an L-shaped connecting block 10 and a quick clamp 11. The third clamping component clamps the portion 203 of the side beam 200 near the cap hinge 4.

[0050] In use, the main locating pin 1 and the auxiliary locating pin 2 are respectively positioned in the middle of the side panel. Figure 6The clamping element is held on the side beam 200 at position 101 of the side panel and the bracket 301 of the front-end module. The hinge locating pin 3 is inserted into the corresponding locating hole in the middle of the lower hinge blade 41. The positioning position of the main locating pin 1 on the side panel 100 is higher than the positioning position of the auxiliary locating pin 2 on the bracket 301 of the front-end module, and lower than the position of the hinge 4. After the lower hinge blade 41 is positioned using the hinge locating pin 3, the pre-installed first connecting bolt 5 is tightened to complete the assembly of the lower hinge blade 41.

[0051] Based on the above-described assembly system for the cap hinge, this application also provides a method for assembling the cap hinge, comprising:

[0052] P1: Tighten the hinge shaft 44 of the hood hinge 4 to the side panel 100 in the Y direction, and pre-install the first connecting bolt 5 on the connecting hole at the lower end of the hinge lower blade 41. The axis of the first connecting bolt 5 is parallel to the Y direction of the vehicle.

[0053] It should be noted that the length direction of the vehicle body is the X-direction, the width direction is the Y-direction, and the height direction is the Z-direction.

[0054] P2: Align the main locating pin 1 and auxiliary locating pin 2 on the auxiliary device with the center of the side panel 100 in the Y direction (see installation location). Figure 6 The corresponding positioning holes on the bracket 301 of the front-end module 300 (101) and the bracket 301 of the front-end module 300.

[0055] P3: Clamp the auxiliary device's clamping parts onto the side beam 200, thereby inserting the main positioning pin 1 and the auxiliary positioning pin 2 into the corresponding positioning holes.

[0056] P4: Insert the hinge positioning pin 3 on the auxiliary device into the corresponding positioning hole in the middle of the lower hinge blade 41 in the Y direction, thereby positioning the lower hinge blade 41 by the auxiliary device.

[0057] P5: Tighten the first connecting bolt 5 to complete the assembly of the lower hinge blade 41.

[0058] P6: Remove the auxiliary device.

[0059] If the hood hinge 4 and / or the body manufacturing precision deviates from the median value during the assembly process, after the hood hinge positioning pin 3 is inserted into the positioning hole of the lower hinge blade 41, the position of the connecting hole of the lower hinge blade 41 is finely adjusted, thereby finely adjusting the position of the lower hinge blade 41 relative to the side wall 100, and after the fine adjustment is completed, the first connecting bolt 5 is tightened.

[0060] It should be noted that the diameter of the connecting hole of the lower hinge blade 41 is larger than the outer diameter of the first connecting bolt 5. Therefore, after the position of the connecting hole of the lower hinge blade 41 is slightly adjusted, the first connecting bolt 5 can also be installed on the side panel through the connecting hole of the lower hinge blade 41.

[0061] The position of the connecting hole of the lower hinge blade 41 is finely adjusted, specifically including:

[0062] As an example, by adjusting the X-direction position of the hinge positioning pin 3, the X-direction position of the connecting hole of the lower hinge blade 41 can be finely adjusted by adjusting the X-direction position of the positioning hole of the lower hinge blade 41.

[0063] As another embodiment, by adjusting the Z-direction position of the hinge positioning pin 3, the Z-direction position of the connecting hole of the lower hinge blade 41 can be finely adjusted by adjusting the Z-direction position of the positioning hole of the lower hinge blade 41.

[0064] Understandably, the X-axis and / or Z-axis positions of the connecting holes of the lower hinge blade 41 can be adjusted as needed. By adding or removing shims between the connecting blocks to absorb errors, the positional accuracy of the hood hinge and the vehicle body matching area is improved.

[0065] Specifically, such as Figure 8 As shown, the two hinge locating pins 3 are connected to the body 17 in the same way. Figure 8 Taking the hood hinge positioning pin 3 on the left side as an example, the hood hinge positioning pin 3 is fixed to the first connecting block 12. The first connecting block 12 is detachably connected to the second connecting block 13 via a second connecting bolt. The second connecting block 13 is detachably connected to the body 17 of the auxiliary device. The axial direction of the second connecting bolt is parallel to the X-direction of the vehicle. Figure 8 (The middle part indicates the horizontal direction).

[0066] As an example, the first connecting block 12 and the second connecting block 13 are L-shaped connecting blocks.

[0067] The X-direction position of the first connecting block 12 is adjusted by increasing or decreasing the number of shims between the first connecting block 12 and the second connecting block 13, thereby driving the hinge positioning pin 3 of the cover to adjust its X-direction position, thereby fine-tuning the X-direction position of the positioning hole of the lower hinge blade 41 and the connecting hole of the lower hinge blade 41.

[0068] like Figure 8 As shown, a third connecting block 14 is provided between the second connecting block 13 and the body 17. The second connecting block 13 is detachably connected to the third connecting block 14 by a third connecting bolt, and the third connecting block 14 is connected to the body 17. The axial direction of the third connecting bolt is parallel to the Z-direction of the vehicle.

[0069] As an example, the third connecting block 14 is an L-shaped connecting block.

[0070] With the first connecting block 12 and the second connecting block 13 relatively fixed, the Z-direction position of the second connecting block 13 is adjusted by increasing or decreasing the number of shims between the second connecting block 13 and the third connecting block 14. This causes the first connecting block 12 to adjust its Z-direction position, thereby adjusting the Z-direction position of the hinge positioning pin 3. This, in turn, finely adjusts the Z-direction position of the connecting hole of the lower hinge blade 41 by finely adjusting the Z-direction position of the positioning hole of the lower hinge blade 41.

[0071] In the scheme of this application, the dimensional chain calculation for a certain vehicle model is shown in Table 2 below:

[0072] Table 2. Z-axis dimensional chain for the cap and side panels.

[0073]

[0074]

[0075] In this application, the cap hinge assembly uses a local reference for positioning and assembly. Compared with the prior art, the actual local DTS is improved by 29%. At the same time, the cap hinge can be finely adjusted with the help of auxiliary devices to improve the assembly accuracy.
