Description:REAR UNDERRUN PROTECTION DEVICE (RUPD) FOR A VEHICLE
FIELD OF THE DISCLOSURE
[0001] This invention generally relates to a field of energy and impact absorption in vehicles, and in particular, relates to an underrun protection device that reduces impact and absorbs energy during a collision event.
BACKGROUND
[0002] The subject matter discussed in the background section should not be assumed to be prior art merely as a result of its mention in the background section. Similarly, a problem mentioned in the background section or associated with the subject matter of the background section should not be assumed to have been previously recognized in the prior art. The subject matter in the background section merely represents different approaches, which in and of themselves may also correspond to implementations of the claimed technology.
[0003] Road safety is a major concern, especially for heavy-duty trucks, which share highways with smaller vehicles. In rear-end collisions, smaller vehicles can slide under the , Claims:CLAIMS
WE CLAIM:
1. A rear underrun protection device (RUPD) (100) for a vehicle comprising:
a truss-reinforced RUPD bar (102) configured to:
distribute impact forces; and
prevent excessive deformation upon collision of the vehicle;
a plurality of gussets (110) integrated to a plurality of rib supporting plates (120) and positioned within a truss plate (114), wherein the plurality of gussets (110) is configured to enhance structural integrity and impact resistance;
a set of reinforcement plates (112) strategically positioned within the truss-reinforced RUPD bar (102), wherein the set of reinforcement plates (112) is configured to improve load-bearing capacity;
a pair of upper mounting brackets (108) and lower mounting brackets (106), securely attached to a vehicle frame, wherein the pair of upper mounting brackets (108) and the lower mounting brackets (108) is configured to provide additional support and reduce localized stress during impact; and
a progressive deformation unit position within the truss plat
