Description
Technical field
The invention belongs to automobile technical fields, and in particular to a kind of bumper tow hook blanking cover split type structure and its assembly side
Method.
Background technique
Towing hook blanking cover is generally disposed on bumper, covers the blanking cover of car puller hook attachment device, which not only needs
Play the role of facilitating trailer, but also should be beautiful, so that blanking cover must have reliably to be wanted convenient for opening and connecting
It asks.And a part that bumper is critically important as vehicle presentation quality, as the appearance and modeling and minute design of automobile are continuous
Improve, bumper moulding be it is more and more novel, requirement of major main engine plants to appearance is also increasingly pursued ultimate attainment, highlights its moulding
It is novel, beautiful.The splitting piece quantity for the different surface treatment that bumper body assembly includes is also more and more, and car puller hook conduct
Platform general part, position are often fixation, when moulding parting characteristic area has with towing hook blanking cover layout area to conflict, are
The not moulded feature of damage insurance thick stick, towing hook blanking cover lower regions are also needed using different surface treatment mode, common place
Reason method is that towing hook blanking cover is done to the design of masking spray structure or splitting piece design, wherein masking spray structure needs reserved hide
Cover technology groove, it is contemplated that technological feasibility, masking slot root width need to be greater than 0.8mm, and bumper itself bulk-breaking fit clearance
It is typically designed to 0.5mm, the parting feature mismatch of masking groove width and bumper itself bulk-breaking, secondly, if bulk-breaking needs up and down
When using different spray painting processing, masking spray structure need to be covered spraying twice, and presentation quality is difficult to control, so more pushing away
Recommend the part design that splits, but this is also to have had higher requirement for engineering design, common problem in addition to towing hook blanking cover above and below
Outside ontology itself matching problem, the cooperation of towing hook blanking cover and bumper and the degree of registration problem of the two parting etc., root are further related to
Basis is because space herein is difficult arragement construction, and is related to multiple cooperations.
Summary of the invention
The present invention is directed at least solve one of the technical problems existing in the prior art.For this purpose, the present invention provides a kind of guarantor
