The invention discloses an embedded operating system virtual machine (HopenVM) and an implementation method of core technology of the virtual machine. The product supports two different embedded operating systems established on a single hardware microprocessor, so that a physical processor chip of one embedded system is converted into a chip system with multiple logics, and a virtualization communication mechanism similar to a hardware communication mechanism is established between the two operating systems. According to the implementation method, two software systems with different characteristics can be logically isolated.

The invention provides a cover plate structure, a display module and a display device. The cover plate structure is used for packaging protection of the display module and comprises a flexible cover plate body and a protective coating, the flexible cover plate body comprises a covering structure and a thinning structure located on the periphery of the covering structure, the covering structure islocated in the middle area of the flexible cover plate body and used for being matched with a display area of the display module, and the protective coating is disposed along an edge of the thinning structure and at least covers a portion of the thinning structure. According to the cover plate structure, the protective coating is arranged on the thinning structure of the flexible cover plate body,the protective coating at least can wrap a part of the thinning structure, so that the edge of the flexible cover plate body is protected, the collision resistance effect of the edge of the flexiblecover plate body is improved, the product strength of the display module and the corresponding display equipment is improved, and the service life of the display module and the corresponding display equipment is prolonged.

The invention relates to the field of technologies for manufacturing accessories of automobile bodies, in particular to a lightweight automobile engine cover which comprises an outer plate and an inner plate. Lock mounting holes, a drowning hole, a stay bar mounting hole and hinge holes are formed in the inner plate, and the outer plate and the inner plate are separately integrally formed and are assembled by adhesive; a plurality of reinforcing ribs and a plurality of boss regions are further arranged on the surface of the side, which clings to the outer plate, of the inner plate; the reinforcing ribs are used for improving the integral deformation resistance of the inner plate; a plurality of glue spilling inlet grooves are formed in the multiple boss regions, and glue can be prevented from spilling to other regions in procedures for applying adhesive to assemble the outer plate and the inner plate. The lightweight automobile engine cover has the advantages that the stiffening ribs are additionally arranged on the inner plate, and accordingly the engine cover deformation resistance of the inner plate can be improved; the lightweight automobile engine cover is made of novel composite materials, is light and has certain deformation capacity owing to elastic characteristics of the thermoplastic composite materials, and excellent effects of protecting pedestrians can be realized.

A body structure of a passenger car, and especially of a convertible, features at least one side door on each longitudinal side of the vehicle. The side door, when closed, connects to adjoining fixed pillars via hinges at one end and via a lock assembly at the other end. For improved crash resistance of the body structure of a passenger car, and especially of a convertible, with a rear engine in the event of a head-on collision, a buttress assembly is installed between the rearward rim of the side door and the adjoining lock-side pillar. The buttress assembly effectively holds the side door in its closed position in the event of a head-on collision, while at approximately the level of the buttress assembly, the side door is braced by a hollow strut that extends in the longitudinal direction of the vehicle.

The invention discloses a power battery pack. The power battery pack comprises a lower shell, a battery module and an upper shell assembly. Two cross beams and a plurality of longitudinal beams are fixedly installed in the lower shell, and the longitudinal beams are arranged between the two cross beams at intervals in the length direction of the cross beams so as to form a plurality of strip-shaped hole sites. The battery module comprises a plurality of battery cells and a plurality of partition plates. The battery cells are placed in the strip-shaped hole sites at intervals in the length direction of the longitudinal beams, and the partition plates are installed between every two adjacent battery cells. And the upper shell assembly covers the battery module and is fixedly connected with the lower shell. According to the power battery pack provided by the invention, the battery cells can be completely fixed, and when the power battery pack is subjected to lateral collision, the lower shell forms a first defense line, and the longitudinal beams form a second defense line, so that the lateral collision prevention capability of the power battery pack can be greatly improved. In addition, the plurality of columns of longitudinal beams can also prevent short circuit in the battery cell caused by overlarge one-time deformation of the power battery pack, so that the service life of the power battery pack is comprehensively prolonged.
