This utility model discloses a slotless AC motor structure based on a reduced-core design, comprising a housing, a stator module, a partial core module, and a rotor module. The housing includes a main body and a base plate. The stator module is built into the housing and includes an annular non-magnetic frame and coils. The partial core module includes several cores, which are mounted one-to-one on a core mounting bracket, with air gaps between adjacent cores. This slotless AC motor structure aims to solve problems such as significant cogging effect, excessive core weight, and inflexible magnetic circuit in traditional motor structures. The motor eliminates the traditional slotted stator structure, adopting a combination design of slotless coils and a partial magnetic core. While ensuring effective control of the magnetic flux path, it significantly reduces motor weight, manufacturing complexity, and improves dynamic response performance.

The utility model relates to automobile parts, and provides a novel knuckle bearing V pusher which comprises a first connecting rod, a second connecting rod, a V-end ball head sub assembly, a first ball pin sub assembly and a second ball pin sub assembly, and the V-end ball head sub assembly comprises a mounting seat, a ball head, a metal bearing outer ring, a ball seat and an end cover. A containing cavity between the ball seat and the end cover and a containing cavity between the ball seat and the installation seat are both filled with lubricating grease, a first spiral oil channel and a second spiral oil channel are formed in the inner wall of the metal bearing outer ring, and an oil channel inlet of the first spiral oil channel is communicated with the lubricating grease in the containing cavity between the ball seat and the end cover. An oil duct inlet of the second spiral oil duct is communicated with lubricating grease in a containing cavity between the ball seat and the mounting seat, and an oil duct outlet of the first spiral oil duct and an oil duct outlet of the second spiral oil duct are both located in a bearing contact area between the metal bearing outer ring and the ball head. The problems that an existing thrust rod assembly is short in service life, and potential safety hazards exist in use of a driver are solved.

This utility model relates to an automatic cleaning device for large storage tanks, comprising: a base, a base support system, a pole system, a rotating seat, a rotating seat support system, an adjustment system, a power system, and a cleaning system. This device offers advantages such as convenient operation, high automation, strong safety, lightweight design, wide applicability, low operating costs and labor intensity, short construction period, high tank utilization rate, good cleaning effect, flexible cleaning effect acceptance methods, and no risk of operator poisoning. It is suitable for large storage tanks of various sizes and can effectively solve various problems in existing tank cleaning technologies.

The present application belongs to the technical field of product packaging, and particularly relates to a well-sealed inner-piercing cover body and a packaging container with the same. In the fields of food, medicine or cosmetics, two or more components are often packaged separately to avoid chemical reaction or quality decline during long-term storage and transportation. The present application can simply and quickly mix and blend two independently sealed materials together. The cover body is used to contain a first material, and a packaging container contains a second material. The cover body is assembled on the packaging container through threaded connection. The cover body comprises a main cover, a secondary cover and a piercing member. The main cover is connected with the bottle body through threads. The piercing member is arranged in the main cover. The secondary cover is arranged on the upper part of the main cover and the piercing member. The present application can conveniently mix as needed, provide more convenient use experience, effectively avoid cross contamination, and has a lightweight structure design, which is suitable for travel and outdoor use, and airtight structure ensures hygiene during storage.

The utility model discloses a lower control arm of a double-fork-arm front suspension, which comprises a control arm body, the control arm body is of a cavity structure formed by buckling and welding an upper plate and a lower plate, and a first extension end, a second extension end and a third extension end of the control arm body are respectively used for connecting a front bushing, a rear bushing and a ball pin assembly; the damping support assembly comprises a damping inner plate, a damping outer plate and a mounting nut, the damping inner plate is embedded in the cavity structure and welded to the inner wall of the upper plate and the inner wall of the lower plate, the damping outer plate is arranged on the outer side of the upper plate and welded to the upper plate, and the mounting nut is fixed to the side, back to the damping outer plate, of the damping inner plate; through holes are formed in the areas, right opposite to the damping inner plate, of the upper plate and the lower plate, a damper mounting channel is formed between the damping inner plate and the damping outer plate, and mounting through holes used for bolt connection are formed in the damping inner plate and the damping outer plate in a right opposite mode. The mounting function integration of the shock absorber can be realized, and the requirements of light weight and structural reinforcement are met.
