Description
Technical field
The invention belongs to automobile production manufacturing field, is related to a kind of attachment structure of compartment gusset and top cover, and in particular to
A kind of attachment structure and welding method of no side window van gusset and top cover.
Background technology
Automobile body side wall and top cover be form body of a motor car main body, wherein in actual production gusset mould input
Ratio larger in Auto panel dies input is account for, now common automobile body side wall typically all carries side window glass, because
This in the welding process of body side wall and top cover, welding gun can pass through body side wall side window be welded, but for
During the welding of gusset and top cover without side window van, it is difficult to welded using two-sided resistance spot welding.Led for above-mentioned technology
Domain, state know that office discloses the patent document that related gusset connects with top cover and included：Patent No. ZL201210592258（Height pushes up miniature visitor
The top cover of car and the bridging arrangement of gusset）、ZL201310520734（A kind of attachment structure of gusset and top cover, connection method and
Automobile）And ZL201320698448（A kind of punching type white body side wall assembly）, but technology disclosed in above-mentioned patent document is deposited
In problems with and shortcoming：For without side window glass, while the vehicle that gusset is long, top cover can not realize two-sided electricity with gusset
Spot welding is hindered, is welded using arc welding, material is yielding in welding process, and using laser welding, cost is higher, economy effect
Benefit is difficult to be guaranteed；Top cover can not carry out two-sided resistance spot welding with roof bow, can only be by the vibration isolation glue of baking foaming, will
Top cover is attached with roof bow, causes that bonding strength is relatively low and cost is higher；In welding process, due on side-wall outer-plate
The welding of section and side-wall outer-plate hypomere needs welding procedure space, and in the low top vehicle of manufacturing development, cap height can be by section
Structure limits so that cap height can not be accomplished minimum, and the height dimension of side glass Edge Distance top cover is larger, and low top
The side of vehicle, there is the gap between one of side-wall outer-plate epimere and side-wall outer-plate hypomere, appearance looks elegant degree is affected, if
Minimum top is realized by cancelling side-wall outer-plate epimere, can be due to the outer surface blunt form of side-wall outer-plate hypomere, side-wall outer-plate
The directly exposed reduction good appearance degree of hypomere, also causes the change for being difficult to cap height.
The content of the invention
The technical problems to be solved by the invention are to overcome the above-mentioned deficiency in the presence of prior art, and provide a kind of knot
The bindiny mechanism of structure no side window van gusset reasonable in design and top cover, it is possible to achieve enter without side window van gusset and top cover
The two-sided resistance spot welding of row is fixed, and can realize that cap height changes, and part generalization degree is high, and structural strength is high and outward appearance is beautiful
See.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：It is a kind of without side window van gusset and
