Abstract
The utility model discloses a kind of panoramic sunroof of automobile top cover and strengthen structure, comprise top cover and skylight reinforced bulkhead, skylight reinforced bulkhead is fixed on all edges inside the opening of skylight, reinforced bulkhead corner, skylight and skylight opening inner side week, skylight reinforced bulkhead and skylight opening inner side week were along the position welding outside corner along being connected with boss structure between corner; Boss structure comprises the plastic skeleton that is plane net trellis, fills inflatable foaming body in the grid of skeleton.Corner between skylight reinforced bulkhead and top cover is set up respectively boss structure, when promoting boss structural strength with plastic skeleton, utilize expandable foaming body to connect top cover and skylight reinforced bulkhead, the support that makes not have before top cover supported corner obtain expanded material be connected, coordinate again periphery solder joint, skylight reinforced bulkhead is tightened together with top cover, realized being rigidly connected between the two, thereby promote the rigidity of whole top cover, the vehicle body problem of shaking while avoiding travelling under limiting condition.
Description
Technical field
The utility model relates to automobile body components, refers to particularly a kind of panoramic sunroof of automobile top cover reinforcement structure.
Background technology
The panorama skylight of automobile is for common skylight, it is large that it has day window ara, broad view, the advantage that fanning effect is good, but often there is following shortcoming in panorama skylight vehicle at present: 1) because skylight glass area is large, top cover needs large area perforate, causes automobile top-cap region rigidity not enough; 2) when vehicle body travels under limiting condition, easily occur jolting or the abnormal condition such as vibration, driver comfort is affected greatly.
Summary of the invention
The purpose of this utility model will provide a kind of panoramic sunroof of automobile top cover to strengthen structure exactly, and this structure can improve automobile top-cap rigidity, and then improves vehicle body rigidity, collision performance, and NVH performance.
For achieving the above object, the technical solution adopted in the utility model is: a kind of panoramic sunroof of automobile top cover is strengthened structure, comprise top cover and skylight reinforced bulkhead, on described top cover, have skylight opening, described skylight reinforced bulkhead is fixed on all edges inside the opening of described skylight, reinforced bulkhead corner, described skylight and described skylight opening inner side week, described skylight reinforced bulkhead and described skylight opening inner side week were along the position welding outside corner along being connected with boss structure between corner; Described boss structure comprises the plastic skeleton that is plane net trellis, fills inflatable foaming body in the grid of described skeleton.
The corner of the utility model between skylight reinforced bulkhead and top cover set up respectively boss structure, when promoting boss structural strength with plastic skeleton, utilize expandable foaming body to connect top cover and skylight reinforced bulkhead, the support that makes not have before top cover supported corner obtain expanded material be connected, coordinate again periphery solder joint, skylight reinforced bulkhead is tightened together with top cover, realized being rigidly connected between skylight reinforced bulkhead and top cover, thereby promote the rigidity of whole top cover, the vehicle body problem of shaking while avoiding travelling under limiting condition, and then improved car load rigidity, collision performance and NVH performance have been improved, boss structure adopts and in plastic skeleton grid, sets the version of expanded material, has modulus high, lightweight, assembles advantage easily.
Further, described skylight reinforced bulkhead is square frame-shaped, between itself and top cover, is connected with four boss structures, and described reinforcement block structured profile coordinates one by one with four corner configurations of described skylight reinforced bulkhead.
Further, described skeleton is provided with a plurality of buckles, and described buckle and described skylight reinforced bulkhead connect and fix, and described top cover is supported in described foaming body laminating.
Further, described skeleton adopts PA66+GF30 material.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, is convenient to more clearly understand the utility model, but they do not form and limit the utility model.
As Fig. 1, shown in Fig. 2, a kind of panoramic sunroof of automobile top cover is strengthened structure, comprise top cover 1 and the skylight reinforced bulkhead 2 (as shown in Figure 3) that is square frame-shaped, on described top cover 1, have rectangular skylight opening 3, described skylight reinforced bulkhead 2 is fixed on 3 inner side week of described skylight opening edge, four corners of described skylight reinforced bulkhead 2 and 3 inner side weeks of described skylight opening are connected with respectively a boss structure 4 along between four corners, the profile of described four boss structures 4 coordinates one by one with four corner configurations of described skylight reinforced bulkhead 2, the boss structure 401 at skylight reinforced bulkhead 2 right front angles as shown in Figure 4, the boss structure 402 of skylight reinforced bulkhead 2 left-front corner as shown in Figure 5, the boss structure 403 at skylight reinforced bulkhead 2 right back angles as shown in Figure 6, the boss structure 404 of skylight reinforced bulkhead 2 left rear corner as shown in Figure 7, these boss structures 4 comprise the plastic skeleton 4-a that is plane net trellis, skeleton 4-a preferably adopts PA66+GF30 material, in the grid of described skeleton 4-a, fill inflatable foaming body 4-b, described skeleton 4-a is provided with a plurality of buckles 5, described buckle 5 connects and fixes with described skylight reinforced bulkhead 2, described top cover is supported in described foaming body 4-b laminating, described skylight reinforced bulkhead 2 was connected along the position spot welding outside corner with 3 inner side weeks of described skylight opening, that is: the position that gets around boss structure 4 on skylight reinforced bulkhead 2 four edges frames is connected along spot welding with 3 inner side weeks of skylight opening respectively.
Fitting process of the present utility model is as follows: first four boss structures 4 are stuck in to four corners of skylight reinforced bulkhead 2, then all the other positions of skylight reinforced bulkhead 2 are connected with top cover 1 spot welding, complete assembling; Principle of work of the present utility model is as follows: boss structure is arranged on skylight reinforced bulkhead 2 with buckle 5 clampings when being welded, during through the baking of paint electrophoresis drying oven, boss structure 4 couples together skylight reinforced bulkhead 2 and top cover 1 by expandable bodies foaming body 4-b, at the cooling post-foaming body of vehicle body 4-b, solidify, top cover 1 is tightened together (as shown in Figure 8) with skylight reinforced bulkhead 2.
The solder joint that only only limits to skylight open circumferential and front and rear part that is connected of existing skylight reinforced bulkhead and top cover, top cover front portion and rear portion also have huge area not to be connected with reinforced bulkhead, especially four of top cover corner portions, thereby caused top cover insufficient rigidity, the utility model is set up boss structure, by expanded material, foam and connect top cover and reinforced bulkhead, the support that four angles that top cover is not supported obtain expanded material be connected, empirical tests, the utility model has improved top cover corner portions and has connected weak problem, and then promoted the rigidity of whole top cover, the vehicle body problem of shaking while avoiding travelling under limiting condition, vehicle body collision performance and NVH performance have been improved, in addition, than traditional passing through, increase the measure that thickness of slab strengthens rigidity, this structure has lightweight, easy to assembly, the advantage that mould investment is lower.
