When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0046] Also see Figure 1a , Figure 1b and Figure 2 The present invention provides a luggage case hinge positioning device for positioning a luggage case hinge. Figure 1a , Figure 1b and Figure 2 They are respectively the front and back structural schematic diagrams of the luggage case hinge positioning device of the present application and the structural schematic diagram of the luggage case hinge. Figure 2 The luggage hinge 1 may include a fixed leaf 12 and a movable leaf 14 that are movably connected; Figure 1a and Figure 1b The luggage case hinge positioning device 21 may include a hinge main positioning mechanism 2101 and a movable leaf positioning pin 2102 .

[0047] The hinge main positioning mechanism 2101 is configured to position the fixed page 12, that is, a positioning structure for fixing the fixed page 12 of the suitcase hinge 1 is provided on the hinge main positioning mechanism 2101, and the positioning structure is suitable for adapting to the shape and structure of the fixed page 12. Exemplarily, the hinge main positioning mechanism 2101 may include a supporting portion (not shown) and an assembling portion (not shown), the supporting portion is used to provide support, and the assembling portion is provided on the supporting portion, and the assembling portion is mainly used to assemble and position the suitcase hinge 1. The specific structure of the assembling portion will be described in subsequent embodiments and will not be repeated here.

[0048] The movable page positioning pin 2102 is connected to the hinge main positioning mechanism 2101, and may mainly include a connecting portion (not shown) and a limiting portion (not shown), the connecting portion being respectively connected to the hinge main positioning mechanism 2101 and the limiting portion, and the extending directions of the connecting portion and the limiting portion are perpendicular to each other, thereby defining a movable page positioning pin 2102 similar to an "L" shape.

[0049] When assembling the hinge, the movable page positioning pin 2102 is plugged into the positioning hole 1402 provided on the movable page 14. When the hinge main positioning mechanism 2101 clamps the fixed page 12 and the movable page positioning pin 2102 is inserted into the positioning hole 1402, the positions of the movable page 14 and the fixed page 12 are relatively fixed. Specifically, the relative angle between the fixed page 12 and the movable page 14 can be pre-adjusted according to the loading state of the final assembly vehicle. When the relative angle between the fixed page 12 and the movable page 14 is fixed, the fixed page 12 and the movable page 14 can be fixed by plugging the movable page positioning pin 2102 into the positioning hole 1402.

[0050] The above-mentioned luggage case hinge positioning device is connected to the positioning hole on the movable leaf 14 by setting a movable leaf positioning pin 2102 connected to the hinge main positioning mechanism 2101. In this way, after the hinge main positioning mechanism successfully positions the fixed leaf, the relative position between the movable leaf and the fixed leaf can also be fixed by the movable leaf positioning pin, ensuring that the luggage case hinge can be accurately positioned during the final assembly, thereby ensuring that the gap and surface difference between the luggage case and the side panel meet the requirements.

[0051] In this specific embodiment, the luggage hinge 1 can be a conventional four-link hinge, and those skilled in the art can also select and adjust it according to actual needs. The movable connection between the fixed page 12 and the movable page 14 means that the portion where the fixed page 12 and the movable page 14 are connected is not fixed, and the movable page 14 can rotate relative to the fixed page 12. Therefore, for the convenience of subsequent description, the end of the movable page 14 connected to the fixed page 12 is now recorded as the connecting end 1404, and the side of the movable page 14 away from the connecting end 1404 is recorded as the movable end 1406.

[0052] In an optional manner, in order to adjust the relative angle between the movable page 14 and the fixed page 12, reference may be made to Figure 2 In the present application, an adjusting bolt 1202 is provided in the area of ​​the fixed page 12 near the movable end 1406 , and the adjusting bolt 1202 abuts against the movable end 1406 .

The movable leaf 14 is also provided with an avoidance position for the movable leaf positioning pin 2102 to pass through at the location where the positioning hole 1402 is provided, and the positioning hole 1402 may be a waist hole. The relative fixation between the movable leaf 14 and the fixed leaf 12 can be achieved by the tension applied by the movable leaf positioning pin cylinder 2103 to the movable leaf positioning pin 2102 and the abutment force applied by the adjusting bolt 1202 to the movable end of the movable leaf 14.

[0054] Furthermore, the relative position between the movable page 14 and the fixed page 12 can be controlled by controlling the stroke of the movable page positioning pin cylinder 2103; further, as Figure 1b As shown, the relative position between the movable page 14 and the fixed page 12 can be adjusted by adding or reducing a spacer 2106 between the movable page positioning pin cylinder 2103 and the movable page positioning pin 2101 .
