This invention provides an active front hatch cover hinge and a pedestrian protection system, belonging to the field of automotive component technology. It includes: a cover seat with a locking block; a pop-up seat rotatably connected to the cover seat; a locking plate hinged to the cover seat and rotatable about its hinge point on a rotational plane, the locking plate having a locking hook; and a tension spring, one end of which is connected to the locking plate and close to the locking hook, the other end of which is connected to the pop-up seat, the tension spring being inclined to the rotational plane of the locking plate. The advantages of this invention are: the hinge can actively pop open the front hatch before a vehicle collision; the pop-up seat can only unlock by pulling the locking plate through the tension spring when subjected to a lifting force; under normal conditions, the pop-up seat remains locked to the cover seat; and the pop-up release structure of the hinge is reversible and reusable.

The application discloses a ball mill barrel lining plate, which comprises a main plate, wherein an installation structure is formed in the main plate, and a lifting strip is integrally fixed on the main plate, and the main plate and the lifting strip are coated with a rubber layer. According to the ball mill barrel lining plate, at least one of the following technical effects is achieved: the main plate and the lifting strip are arranged in an integrated structure, and then a rubber layer is coated outside, so that the weight of the barrel lining plate is greatly reduced, the lifting strip does not need to be aligned with the main plate during installation, the installation difficulty of the barrel lining plate is greatly reduced, and the installation time of the barrel lining plate is shortened; meanwhile, the weight of the barrel lining plate is reduced, so that the demand for power is greatly reduced, and the energy-saving effect is achieved; the rubber layer coated outside the barrel lining plate can also play a buffering role, the noise generated during the use of the mill is greatly reduced, and the negative influence on the hearing of workers is avoided.

The utility model provides a kind of robot sole and robot, robot sole includes tip, sole main body and elastic member;Tip and sole main body are rotatably connected, so that robot sole has passive degree of freedom in walking process, improve the stability and flexibility of robot walking.Elastic member is rotatably connected with tip and sole main body respectively, the rotating direction of sole main body relative to tip is same with the rotating direction of elastic member relative to tip and sole main body;Elastic member is deformable in the direction from the one end of sole main body towards tip to the one end of sole main body away from tip.Elastic member can be deformed to play the role of buffering, effectively absorb the impact force generated in the instant of landing, reduce the noise generated when walking.Elastic member deforms along the length direction of robot sole, and the deformation space is larger, which can provide greater range of buffering force, reduce the overall thickness size of robot sole, and can be adapted to more models and sizes of robot, improve the scope of application.
