The utility model relates to a kind of energy dissipation reinforcing assembly for RC frame column, comprising: prefabricated ECC plate, for being attached to the surface of structural column and being fixed with structural column;Energy dissipation piece, for being fixed on floor and being resisted with prefabricated ECC plate, suitable for when structural column vibration makes prefabricated ECC plate and energy dissipation piece relative movement, and make prefabricated ECC plate deformation, by the friction between prefabricated ECC plate and energy dissipation piece and the deformation energy dissipation of prefabricated ECC plate.This application plays the role of increasing the section of column by prefabricated ECC plate, realizes the reinforcement of structural column, and it is convenient to construct and low in cost;When structural column is vibrated, it drives prefabricated ECC plate to move relative to energy dissipation piece, utilizes the friction energy dissipation between prefabricated ECC plate and energy dissipation piece, structural column deformation makes prefabricated ECC plate itself deform, by the deformation energy dissipation of prefabricated ECC plate, the function of two-stage energy dissipation is realized, to effectively improve structural damping energy dissipation performance, improve structural seismic bearing capacity.

This invention relates to a new energy battery cooler, belonging to the field of new energy vehicle battery cooling technology. The new energy battery cooler includes a battery base, a controller, a protective shell, and a battery pack. The controller and protective shell are fixedly installed on the top of the battery base, and the battery pack is disposed inside the protective shell. A cooling flow guiding mechanism is included, comprising a contact shell, a cooling component, and a heat-conducting component. The contact shell is fixedly installed on the outside of the battery pack. By setting a cooling flow guiding mechanism on the outside of the battery pack, a passive adaptive flow guiding function not found in traditional liquid cooling structures is achieved. A composite layer of shape memory alloy memory valves and phase change microgrids is introduced into the cooling channel. When the battery pack locally heats up, the phase change layer absorbs and diffuses heat, while the memory valves deform to expand the channel cross-section, causing the coolant to automatically increase flow to the hot spot area to enhance heat transfer. This dynamically adjusts the local cooling capacity and significantly improves temperature uniformity.

The application provides a charging socket, and relates to the technical field of charging accessories. The charging socket comprises at least two power terminals, the power terminals are provided with connecting end faces, at least two connecting assemblies, the two connecting assemblies are connected with the connecting end faces of the two power terminals in one-to-one correspondence, and at least four conductive pieces, at least one power terminal is connected with at least two conductive pieces through the connecting assembly. The application connects a single power terminal with multiple conductive pieces (such as at least two conductive pieces) through the connecting assembly, so that the charging power is increased. Compared with the method of increasing the charging power by using a single large-section wire, since the increased power and total current-carrying capacity remain unchanged, the single large-section wire is replaced by multiple conductive pieces, so that the cross-sectional area of each conductive piece is smaller than that of the single wire, the conductive piece with a small cross section is easier to prepare, and the cross section is smaller, so the conductive piece is easier to bend and wire, and assembly is facilitated.
