The invention relates to the technical field of battery pack installation, and provides a new energy automobile battery installation structure and method.The new energy automobile battery installation structure comprises an installed battery pack and an installation base fixed to an automobile chassis and located above the battery pack, and further comprises a connecting base forming a damping platform and internally provided with a damping cavity; the plurality of connecting seats are distributed outside the battery pack and are positioned right below the mounting seat; the locking part is arranged on the locking part and is used for quickly limiting or separating the movable part from the mounting seat in an eccentric rotation manner; the connecting seat, the movable part and the locking part are sequentially arranged at the joint of the battery pack and the mounting seat, the connecting seat is detachable so that the movable part can be conveniently assembled, overhauled and the like, the movable part is detachable so that the movable part can be conveniently overhauled and replaced, and the locking part fixes the movable part and the mounting seat in a threaded mode, so that the structure is simple and reliable; a movable space is reserved between the connecting seat and the movable part, and a damping sheet is arranged, so that a damping effect can be formed between the battery pack and the chassis.

A photoelectric conversion element includes a photoelectric conversion portion, a first infrared emission layer that is formed on the photoelectric conversion portion and includes a first material selected from one or more of Y2O3, HfO2, and ZrO2, and a second infrared emission layer that is formed on the first infrared emission layer and includes a second material selected from SiO2 or Al2O3.

The present invention discloses a mobile base type magnetic wheel speed regulator, including a pedestal, a driving motor and a magnetic wheel transmission mechanism, wherein a lifting member is arranged on the pedestal, a transmission member is arranged on the first vertical frame, and the driving motor acts on the magnetic wheel transmission mechanism through the transmission member; a pneumatic rod is installed on the equipment frame, a pressure plate is movably arranged in the groove, a bending frame is fixedly arranged at the bottom of the sliding frame, and a compression structure and a parallel linkage member are also arranged in the square frame. In the present invention, firstly, by reducing the load weight of the lifting member, it is ensured that it can achieve a long-term stable supporting effect, and since the bottom of the sliding frame can be stably supported, the accuracy of the speed regulation of the magnetic coupling is guaranteed; secondly, during the adjustment process, since the sliding frame moves along the roller, the friction resistance to the sliding frame with a heavier load is reduced, and the wear on the bottom of the sliding frame is reduced, thereby further ensuring the accuracy of the speed regulation of the magnetic wheel speed regulator.

The invention relates to a bag holder, in particular to a four-connecting-rod tilt cylinder bag opening type bag holder. A first lifting assembly and a second lifting assembly in the bag clamping device are oppositely arranged on the two sides of a main frame, each of the first lifting assembly and the second lifting assembly comprises a first linear driving piece and a four-connecting-rod mechanism, and a tailstock of each first linear driving piece is hinged to the upper end of the main frame through the corresponding four-connecting-rod mechanism; the first bag opening rod and the second bag opening rod are arranged on the two sides of the front protection plate and the rear protection plate and installed at the output ends of the first linear driving pieces in the first lifting assembly and the second lifting assembly correspondingly. The first bag opening assembly and the second bag opening assembly are arranged on the sides, away from each other, of the front protection plate and the rear protection plate correspondingly, and the mounting ends of the first bag opening assembly and the second bag opening assembly are hinged to the front protection plate and the rear protection plate correspondingly. The two output ends of the first bag opening assembly and the two output ends of the second bag opening assembly are hinged to first linear driving piece front bases in the first lifting assembly and the second lifting assembly respectively. The load weight of the output end of the first linear driving part is greatly reduced, and the structure is greatly simplified.
