2results about How to "Increase buffer distance" patented technology

This application relates to a method, device, computer equipment, and medium for active rearward sliding safety control of automotive seats. The method includes: collecting vehicle state data and surrounding traffic environment data; constructing driving environment time-series data including multiple frames of driving environment data based on the vehicle state data and surrounding traffic environment data; inputting the driving environment time-series data into a collision time prediction model to obtain the collision time; detecting whether safety control conditions are met based on the collision time, vehicle speed, and the relative speed of the target; responding to the satisfaction of safety control conditions, determining the relative collision speed based on the collision time, vehicle speed, and target relative speed; determining the seat rearward sliding distance based on the relative collision speed; determining the rearward sliding seat based on the current occupant status; and controlling the rearward sliding seat to slide back by the specified distance when a collision occurs. This method improves the coordinated energy absorption efficiency of the restraint system and the vehicle body structure, effectively reducing injuries to occupants during a vehicle collision.

This utility model discloses an ash collection device for the convection zone of a waste heat boiler, including a cold ash hopper. A sealing sand trough is provided above the cold ash hopper, and the two are connected by a flange. A water-cooled wall is provided at the top of the sealing sand trough, and a flexible connection is provided at the bottom of the cold ash hopper. A scraper conveyor is provided below the flexible connection, and the two are fixedly connected. This utility model increases the buffer distance for coke impact on the cold ash hopper by changing the connection method and structure between the cold ash hopper, the upper water-cooled wall, and the lower scraper conveyor, thereby preventing a large amount of coke from impacting the water-cooled fireplace tubes and the scraper conveyor chain, eliminating the risk of deformation and leakage of the water-cooled fireplace tubes or damage to the scraper conveyor. After completion, it can achieve the goal of safe and stable operation of the waste heat boiler scraper conveyor and water-cooled wall. It is easy to operate and highly practical.
