Benefits of technology

This new technology allows for precise adjustment during medical procedures by controlling how much pressure needs be applied on specific parts within an object's body while minimizing any harm or injury caused due to movements that are larger than necessary when they shouldn’t happen.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving upon existing methods used during vehicle crashes testing (Bruker) tests on dummy hips without damaging them or requiring expensive hardware modifications.

Abstract

The invention relates to an automobile crash test dummy hip joint calibration device, which comprises a rack, a hip joint fixing frame, a force applying rod having an end inserted into a thigh hole of a dummy hip joint and connected with the dummy hip joint fixedly, a lifting mechanism and a control system connected with the lifting mechanism and used for controlling the work of the lifting mechanism. The control system comprises a stroke control switch for controlling the lifting mechanism to apply an acting force to the force applying rod, so that when an included angle between the force applying rod and a horizontal plane exceeds a certain angle, the stroke control switch can control the lifting mechanism to stop applying the acting force to the force applying rod. The calibration device is provided with the stroke control switch which can prevent the damage to the dummy hip joint and the force applying rod due to over large motion stroke (that is over large included angle formed between the force applying rod and the horizontal plane) when one end of the force applying rod moves up and down, thereby protecting the dummy hip joint, as well as the force applying rod.
