Description:A VEHICLE REAR STRUCTURE FOR ABSORBING SLOW SPEED IMPACT

TECHNICAL FIELD
[0001] The present disclosure relates generally to a vehicle rear area and in particular relates to a vehicle rear structure for absorbing slow speed impact.

BACKGROUND
[0002] Generally, tail lights are provided in vehicle rear to make a car visible in dark. The tail lights provide a safety aspect to the vehicle by showing rear edge of the vehicle to allow other drivers to appropriately gauge the size and shape of the vehicle. In addition, tail lights allow other vehicles to see the vehicle in inclement weather such as rain or snow. Any damage to the tail lights, due to rear impact, may put life of passengers in danger.
[0003] Tail lights of different specifications are available in the market. One of the tail lights designs includes long lamp specification which runs across width of the vehicle. To prevent damage to tail lights, structure inside rear bumper is provided in rear area of the vehicle.
[0004] Referring to FIG. 1 illustrating rear structure of a vehicle in accordance with existing art. The rear area 100 of the vehicle comprises a back panel 101 having its lower end connected with floor panel of the vehicle forming a joinery. The back panel 101 has a first flank region 101a, a second flank region 101b and a middle region 101c. The middle region 101c is in between the first flank region 101a and the second flank region 101b. To prevent damage to the tail light (long lamp type) in vehicle rear, a rear cross member assembly 102 is provided on the back panel 101. The rear cross member assembly 102 comprises a plurality of impact absorbers 102a and a cross bar 102b. The impact absorbers 102a are provided on each of the first flank region 101a and the second flank region 101b of the back panel 101. The impact absorbers 102a are bolted on the back panel 101. The cross bar 102b is laterally attached to the impact absorbers 102a and a distance is maintained between the back panel 101 and the cross bar 102b. The cross bar 102b prevents any damage to the tail lights (long lamp type) in the central zone of the vehicle rear area.
[0005] One of the drawbacks of using the existing rear cross member assembly 102 is that the assembly has variable strength throughout its length. The rear cross member assembly 102 is weaker in the middle region and stronger in the flank regions. This deteriorates slow speed crash performance of the vehicle and reinforcing of the cross member structure is required. Further, the rear cross member assembly 102 is heavy due to presence of cross bar and reinforcements 102b which is a solid continuous assembly of metal.
[0006] Another drawback of using the existing rear cross member assembly 102 includes packaging space requirement. The packaging space requirement for rear cross member assembly 102 is more as an additional space on the rear area 100 needs to be protected from slow speed impact when the tail light has long light specification.
[0007] Accordingly, there is a need for a vehicle rear structure for absorbing slow speed impact to prevent damage to the tail light (Long lamp type) without compromising with the strength of the structure, minimum additional weight and without impacting layout for rear Bumper.
