The utility model further improves: the described additional strengthening side of comprising muscle and circle muscle; Described round muscle is glued on the described raising-plate; Described side's muscle is fixed on the described raising-plate.
The utility model further improves: described positioning unit comprises knock hole, locating surface and cross bar; Described knock hole is opened on described locating surface; Described cross bar be distributed in described knock hole around.
The utility model further improves: described positioning unit also comprises the auxiliary positioning face; Described auxiliary positioning face is corresponding with described locating surface and cooperate and to position.
The utility model further improves: described raising-plate can be flat shape or arch; It is even to guarantee the gap that described raising-plate has identical curvature with the top cover that welds with it.
The utility model further improves: described raising-plate is for just or fall several font structures; Described raising-plate also is provided with flange.
The utility model further improves: described raising-plate is provided with everywhere sectional type side's muscle and six places circle muscle gluing to strengthen intensity; Described raising-plate is provided with two positioning units.
The beneficial effects of the utility model are: back timber has improved 2.79HZ with top cover mode, more the intensity of the top cover of actv. raising; The back timber arc guarantees with the top cover gap even with top cover curvature; A few font structures and the side's of employing muscle are used to strengthen back timber intensity; The right-angled crossing muscle is as the knock hole face, and the part has strengthened the intensity of punching profile; The knock hole face perpendicular to Z to, guarantee that punching press finishes punching in same operation and guarantee the knock hole precision, thereby guarantee the welding accurate positioning.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As Fig. 1, a kind of back timber structure that improves top cover intensity comprises raising-plate and welding edge; Described welding edge is positioned at the end of described raising-plate; Described raising-plate is provided with additional strengthening and positioning unit; Described additional strengthening and positioning unit are symmetrically distributed in the middle part of described raising-plate.
The described additional strengthening side of comprising muscle and circle muscle; Described round muscle is glued on the described raising-plate; Described side's muscle is fixed on the described raising-plate.
Described positioning unit comprises knock hole, locating surface and cross bar; Described knock hole is opened on described locating surface; Described cross bar be distributed in described knock hole around.
Described positioning unit also comprises the auxiliary positioning face; Described auxiliary positioning face is corresponding with described locating surface and cooperate and to position.
Described raising-plate can be flat shape or arch; It is even to guarantee the gap that described raising-plate has identical curvature with the top cover that welds with it.
Described raising-plate is for just or fall several font structures; Described raising-plate also is provided with flange.
Described raising-plate is provided with everywhere sectional type side's muscle and six places circle muscle gluing to strengthen intensity; Described raising-plate is provided with two positioning units.
Below by a preferred embodiment the utility model is further specified, a kind of back timber structure that improves top cover intensity comprises raising-plate and welding edge 8; Described welding edge 8 is positioned at the end of described raising-plate; Described raising-plate is provided with additional strengthening and positioning unit 4; Described additional strengthening and positioning unit 4 are symmetrically distributed in the middle part of described raising-plate.The back timber arc guarantees with the top cover gap even with top cover curvature; A few font structures and the side's of employing muscle 27 are used to strengthen back timber intensity; Sectional type pipe muscle is symmetrically distributed in the two ends of this back timber, as the label among Fig. 11,3,5, and gluing and being bonded on this back timber on this pipe muscle; Right-angled crossing muscle 43 is as the knock hole face, the part has strengthened the intensity of punching profile, because the right-angled crossing muscle is just adopted in the location, hole, both improved the welded grider integral intensity, the local again intensity that has strengthened the punching profile, stress concentration during punching around the hole, the cross muscle can not cause problems such as cracking, distortion; The knock hole face perpendicular to Z to, guarantee that punching press finishes punching in same operation and guarantee the knock hole precision, thereby guarantee the welding accurate positioning; At pipe muscle 1,3,5 place's gluings, utilize knock hole 41 and profile 42 on the part to locate as welding, back timber is welded on the both sides of top cover at body work shop, be equivalent to that in both sides and top cover weld together welded grider is had an effect of supporting, and the mode by middle gluing is connected with top cover and supports top cover again, thereby improves top cover intensity.And auxiliary positioning face 6 cooperates knock hole 41 and location profile 42 to position processing together.
This back timber is provided with the many places additional strengthening with its middle part symmetry, as square muscle and circle muscle, adopts the many places positioning unit to position.As shown in Figure 1, adopt 2 place's knock hole and locating surfaces; 2 place's auxiliary positioning faces; 4 prescription muscle; 6 places pipe muscle gluing; Welding edge then is positioned at the both sides of this back timber.This back timber also has flange 9, and this flange place is fluted, and the mode of employing gluing realizes the support to top cover, and the structure of this flange also is to adopt ".
This back timber can use simultaneously with the general assembly beam, and skin can refill the general assembly beam after body work shop is welded on this back timber on the top cover, and the layout that remedies back timber still can't satisfy the defective of top cover intensity; The general use of welded grider is equipped with on the vehicle of resisting configuration stubbornly at top cover, and the utility model also can adopt soft top; This back timber adopts down a few font structures; Described back timber can be big arch with the curvature radian of top cover.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
