Description

TECHNICAL FIELD

[0001] The utility model relates to roof crossbeam technical field especially relates to a light weight vehicle body assembly roof crossbeam assembly structure. BACKGROUND

[0002] In modern automobile manufacturing industry, with the continuous improvement of the light weight, safety performance and ride comfort requirements of vehicles, the design and optimization of automobile body structure become one of the key technologies. Among them, the roof crossbeam of the vehicle body is an important structural component for supporting and protecting the roof of the vehicle, and its design and material selection directly affect the structural strength, impact resistance and passenger safety of the whole vehicle.

[0003] Traditionally, many vehicle models use crossbeam structure to support the roof of the vehicle, which meets the basic structural connection requirements to a certain extent, but its limitations are increasingly prominent. Specifically, the supporting surface of the crossbeam is relatively small, which limits the contact area with the roof of the vehicle, thereby limiting the full play of the supporting effect. In the case of extreme conditions such as collision and rollover, due to the insufficient supporting surface, the roof of the vehicle is prone to local deformation or even damage due to uneven stress, which not only affects the overall structural integrity of the vehicle, but also may seriously threaten the life safety of the passengers. SUMMARY

[0008] The X-shaped crossbeam comprises a middle ring, a strut is integrally formed and installed at each corner of the middle ring, and two expansion ends are arranged on the strut.

[0009] As an improved technical scheme, the opposite ends of the linear cross beam one and the linear cross beam two are provided with limiting grooves, one end of the support strip away from the middle ring is welded with a connecting block close to one side of the linear cross beam one or the linear cross beam two, and the connecting block is detachably connected with the corresponding limiting groove.

[0010] As an improved technical scheme, the four corners of the limiting groove are welded with positioning rods, and the four corner ends of the connecting block are provided with clamping holes for the positioning rods to pass through.

[0011] As an improved technical scheme, the positioning rod is sleeved with a rubber gasket close to one end of the limiting groove.

[0012] As an improved technical scheme, the center of the middle ring is provided with a weight-reducing hole, the expanding end is provided with a weight-reducing groove one, and the support strip is provided with three weight-reducing grooves two.

[0013] As an improved technical scheme, three weight-reducing grooves three are equidistantly arranged on the linear cross beam one.

[0014] After the above technical scheme is adopted, the beneficial effects of the utility model are:

[0015] 1. The utility model realizes large-range support to the top cover through the cooperation of the linear cross beam one, the linear cross beam two and the X-shaped cross beam, guarantees the contact surface of the support to the top cover, and further improves the support, compression resistance and impact resistance effects to the top cover. The full play of the support effect is beneficial to improve the riding safety of passengers. Meanwhile, two expanding ends are arranged on each of the four support strips, which further expands the contact surface with the top cover. The arch surface arranged thereon matches the curvature of the top cover, guarantees the full lamination of the cross beam assembly and the automobile top cover for support, and improves the support effect.

[0016] 2. The utility model sets the weight-reducing hole on the middle ring, the three weight-reducing grooves two on the support strip, the weight-reducing groove one on the expanding end and the three weight-reducing grooves three on the linear cross beam one, which effectively reduces the weight of the cross beam assembly, and further reduces the overall weight of the vehicle body.

[0017] 3. The clamping between the positioning rod and the clamping hole clamps the connecting block in the limiting groove, and the X-shaped cross beam is detachably installed between the linear cross beam one and the linear cross beam two, which is convenient for the installation of the X-shaped cross beam. Meanwhile, when the linear cross beam one, the linear cross beam two and the X-shaped cross beam are installed on the vehicle body, the X-shaped cross beam can be clamped on the vehicle frame for fixation after the linear cross beam one and the linear cross beam two are welded on the vehicle frame, without welding the X-shaped cross beam, which simplifies the installation process of the cross beam assembly and improves the convenience.
