Publication number: 20240067237Abstract: A train having a protection device with self-adaptive crashworthiness is disclosed, which relates to the technical field of safety protection of trains. The train includes multiple vehicles, a head vehicle is located at the head end of the train, and a head vehicle energy absorbing coupler mechanism is mounted at the front end of the head vehicle, each two adjacent vehicles are connected to each other by a middle vehicle energy absorbing coupler mechanism. An image acquisition mechanism and a radar detector are mounted at the head vehicle for monitoring whether there is an obstacle ahead the train, measuring distance and collision speed between the train and the obstacle, and for transmitting measured data to a processing center of the train, the processing center optimizes and adjusts impact force at the head vehicle energy absorbing coupler mechanism and the middle vehicle energy absorbing coupler mechanisms based on a collision situation.Type: ApplicationFiled: November 3, 2022Publication date: February 29, 2024Applicant: Central South UniversityInventors: Jian LI, Guangjun GAO, Zihao XIE, Yao Yu, Jialin LI

Publication number: 20210094592Abstract: A reusable collision energy absorption device for a rail vehicle includes an impacted rod, a damping structure including a damping plug, a guide tube and a damping elastic element, a return structure including a return piston and an elastic return element, an outer tube having a tubular structure, and an interior partitioned into a front cavity and a rear cavity through a partition plate provided with a damping hole in the form of a through hole. A portion of the damping plug is in the damping hole when the damping plug is in an initial position, and the damping plug can move in a front-rear direction when the device is impacted. A gap between a radial thickest portion of the damping plug and the damping hole allows the fluid to circulate between the front cavity and the rear cavity.Type: ApplicationFiled: October 30, 2018Publication date: April 1, 2021Applicant: CENTRAL SOUTH UNIVERSITYInventors: Guangjun GAO, Weiyuan GUAN, Shuai WANG

Patent number: 10556603Abstract: A collision energy absorption apparatus for a rail vehicle, including a connection member, a base, and an energy-absorption splitting tube provided on the outer side in the radial direction of the connection member. The inner wall and outer wall of the energy-absorption splitting tube includes one or more pairs of slits having radial positions corresponding to each other. Each pair of slits includes an inner slit and an outer slit. Each slit is a non-closed linear slit. The slit has a width of 0.05-0.8 mm. The sum of the depths of each pair of slits is less than the wall thickness of the energy-absorption splitting tube.Type: GrantFiled: September 30, 2016Date of Patent: February 11, 2020Assignee: CENTRAL SOUTH UNIVERSITYInventor: Guangjun Gao

Patent number: 10435045Abstract: An anti-derailment apparatus for a bogie of a rail vehicle of the disclosure comprises at least one mounting seat and an anti-derailment slide plate. The transverse orientation of the anti-derailment slide plate on the mounting seat and the extending length of the anti-derailment slide plate in the vertical direction meet the following requirements simultaneously: 1) making the anti-derailment slide plate located at the inside of the ground rail when the rail vehicle runs normally; 2) when at least one wheelset of the rail vehicle climbs rail, the anti-derailment slide plate acts on the ground rail to form lateral limitation points so as to limit the freedom of the rail vehicle and make it still constrained by the ground rail.Type: GrantFiled: January 18, 2016Date of Patent: October 8, 2019Assignee: CENTRAL SOUTH UNIVERSITYInventor: Guangjun Gao

Publication number: 20180208219Abstract: Disclosed is a telescopic type collision energy absorption device for a rail vehicle, which includes two sets of mechanisms functioned individually. The two sets of mechanisms are mounted respectively on either side of end portion of the vehicle. Each set of the mechanism includes an anti-climber, an energy absorption circular tube, pull rings, cutters, cutter fixing blocks, a mounting base, a cutter base, a guide cartridge, a double-acting type air cylinder, a base, bolts, torsional springs, pins, locating slots, a double-acting type solenoid valve, a controller and air storage tank. When the energy absorption device is in a non-operating state, the double-acting type air cylinder is in a state of tension where it pulls the energy absorption circular tube in such a way that the energy absorption circular tube is retracted into the interior of the guide cartridge, the cutters are pressed against the outer wall of the energy absorption circular tube.Type: ApplicationFiled: October 15, 2016Publication date: July 26, 2018Inventor: Guangjun Gao

Patent number: 9839391Abstract: An opto-mechanical system for operation with a container containing a fluid to be administered in an eye or a container such as a syringe for example to administer an insulin injection. The mount of the system is equipped with an optical system and a processing/recording means configured to receive optical data, from light (visual or infra-red) reflected by an area in the vicinity of the eye, which data represents temporal and spatial characteristics of a process of administering drops of the fluid from the container into the eye. Image analysis software or human observation may be used to analyze the recorded images.Type: GrantFiled: November 6, 2013Date of Patent: December 12, 2017Assignee: EYE DROP IMAGING TECHNOLOGY, LLCInventors: Alexander M. Eaton, Gabriel Gordon, Guangjun Gao
