Description

Technical Field

[0001] The utility model relates to the technical field of bumper beams, and more specifically, to a front bumper beam cover plate of a vehicle body. Background Art

[0002] The front cross beam of a car is the first cross beam behind the front bumper. The cross beam of a car is not only used to ensure the torsional rigidity of the frame and bear the longitudinal load, but also to support the main components of the car. The cross beam cover is a part of the cross beam assembly, and the combination of the cross beam and the cross beam cover achieves the purpose of strengthening the collision strength and torsional strength of the cross beam.

[0003] At present, when the existing cross beam cover is assembled or separated from the front bumper cross beam, due to the interference fit and connection between the cover and the cross beam, when the staff removes the connecting parts at the connection point from between the two, the cover and the cross beam are still in a clamped state, which makes it inconvenient to separate the two. If the two are only connected without a clamping fit, the connection stability of the cover and the cross beam will be affected. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model aims to provide a front bumper beam cover for a vehicle body.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a front bumper beam cover for a vehicle body, comprising a main body component and positioning parts symmetrically connected to both ends of the main body component.

[0006] Wherein, the main body component includes a U-shaped cover plate, and the front side and the rear side of the cover plate are integrally formed with arc portions.

[0007] A connecting portion is provided on the top of the cover plate, and the connecting portion includes a connecting protrusion and a connecting hole which are both integrally formed on the top of the cover plate. The top surface of the connecting protrusion is rectangular, and the top surface of the connecting hole is circular.

[0008] Both groups of positioning parts include positioning plates integrally formed at the ends of the cover plate. The positioning plates are U-shaped, and the bottom of the positioning plates is flush with the bottom of the cover plate, while the top middle section of the positioning plates is lower than the height of the two ends of the top.

[0009] The utility model is further configured as follows: a connecting plate is arranged on the top of the cover plate, the bottom surface of the connecting plate is fitted with the connecting protrusion and the top surface of the connecting hole, and a profiling plate is arranged on one side of the connecting plate, and the side wall of the profiling plate is fitted with the side wall of the cover plate.

[0010] By adopting the above technical solution, when the cover plate is connected to the beam, the cover plate is stuck on the outside of the beam, and the inner wall of the beam fits against the cover plate. At this time, the two can be clamped together, and the inner cavity space of the arc-shaped portion is not occupied. When the cover plate and the beam are separated, the staff can use tools to clamp the inside of the arc-shaped portion, and use the angle formed between the arc-shaped portion and the beam to lift the cover plate from the beam. This not only avoids the inconvenience of separating the cover plate and the beam, but also ensures the stability of the connection between the two. By setting the connecting protrusions and the connecting holes, the strength of the middle section of the cover plate is enhanced, and it is used to balance the stress of the cover plate.

[0011] The utility model is further configured as follows: a positioning protrusion is integrally formed on the top of the two positioning plates, a first positioning hole and a second positioning hole are respectively formed on the top of the positioning plate and the top of the positioning protrusion, and the diameters of the first positioning hole and the second positioning hole are both set to 8.0±0.2mm.

[0012] The utility model is further configured as follows: a limiting plate is integrally formed on one side of the positioning plate away from the cover plate, the limiting plate is arranged at an end away from the positioning plate and is inclined downward, and the width of the limiting plate is smaller than the width of the corresponding positioning plate.

[0013] The utility model is further configured as follows: grooves are provided between the two sides of the limiting plate and the side walls of the corresponding positioning plate, and the sum of the inner diameters of the two grooves is the width difference between the limiting plate and the corresponding positioning plate.

[0014] The utility model is further configured as follows: through holes are provided on the tops of the two positioning plates, and the diameters of the through holes are set to 20±1 mm.

[0015] When the cover plate and the positioning plate are clamped with the cross frame, the limit plate is at the end of the cross frame. Since the initial state of the limit plate is tilted downward, the cover plate and the positioning plate are prevented from moving laterally. In addition, when the cover plate and the positioning plate are clamped with the cross frame, the staff can limit the two ends of the cross frame by bending the angle of the limit plate, thereby further improving the connection stability. By setting a through hole, the strength of the positioning plate is enhanced, and it is used to balance the stress of the cover plate and the positioning plate.

[0016] In summary, the present application includes at least one of the following beneficial technical effects:

[0017] (1) By providing the arc portion, when the cover plate and the cross beam are separated, the staff can use a tool to clamp the inside of the arc portion and use the angle formed between the arc portion and the cross beam to lift the cover plate from the cross beam. This not only avoids the inconvenience of separating the cover plate and the cross beam, but also ensures the stability of the connection between the two.

[0018] (2) When the cover plate and the positioning plate are connected to the cross frame, the limit plate is at the end of the cross frame. Since the initial state of the limit plate is tilted downward, the cover plate and the positioning plate are prevented from moving horizontally. In addition, when the cover plate and the positioning plate are connected to the cross frame, the staff can limit the two ends of the cross frame by bending the angle of the limit plate to further improve the connection stability.
