The application realizes automatic and accurate control, reproduces real working conditions, improves the reliability of test data, adapts to the testing requirements of multiple scenes, and guarantees the operation reliability of aviation key systems.

This invention discloses a high-expansion battery pack with an ultra-light piston structure, comprising a piston battery module, a cylinder, and a battery pack casing. The piston battery module and the cylinder are disposed inside the battery pack casing. The piston battery module includes an array of individual battery cells and a piston. A first end of the individual battery cell array is fixedly connected to the piston, and a second end of the individual battery cell array is fixedly connected to the battery pack casing. The cylinder is fixedly connected to the battery pack casing. The cylinder has a cavity for accommodating the piston. The expansion and contraction of the individual battery cell array drives the piston to reciprocate within the cavity. The cavity limits the piston, ensuring that the reciprocating motion of the piston is a linear motion along the expansion and contraction direction of the individual battery cell array. This invention achieves the technical effect of stable external dimensions during the charging and discharging process of the battery pack, effectively avoiding damage to the casing caused by the expansion and contraction of the battery module.

The utility model belongs to the field of intracranial image collection, especially a head -wearing intracranial blood vessel image collection analysis appearance, the present equipment cannot be adapted to the skull surface of different patients and lack flexible tightness adjustment, leading to the discomfort of the equipment use, and the data acquisition accuracy is reduced, the present scheme is proposed, it includes elastic headgear and near infrared spectrum sensor, the inner wall fixed setting of elastic headgear has the sponge pad, the top of elastic headgear is annular and is sewed with even distribution's multiple plastic batten, be provided with wearing subassembly on elastic headgear, and this wearing subassembly is convenient for the patient of different head size and wears. The utility model through the combination of elastic headgear, plastic batten and wearing subassembly, not only realizes the self -adaptation of the skull surface of different patients, but also can carry out tightness adjustment, improves the comfort and adaptability of equipment, ensures the safety and stability of long time use.

This application relates to the field of charging pile technology, and provides a cable suspension device and a charging pile. The cable suspension device includes: a column body, a cable suspension part, and a counterweight part. The cable suspension part includes a movable pulley assembly, a fixed pulley assembly, and a flexible traction assembly. The fixed pulley assembly is installed on the top of the column body. The movable pulley assembly is installed on the column body and located below the fixed pulley assembly. The first end of the flexible traction assembly is fixedly connected to the top of the column body. From the first end of the flexible traction assembly, the flexible traction assembly passes sequentially around the movable pulley assembly and the fixed pulley assembly, and the second end of the flexible traction assembly is connected to the cable. The counterweight part is installed on the column body and connected to the movable pulley assembly. The gravity of the counterweight part is transmitted to the flexible traction assembly through the movable pulley assembly. The counterweight part includes multiple counterweights, which are arranged sequentially, and adjacent counterweights are detachably connected.

The utility model discloses an egg conveying line protection device, which relates to the field of egg conveying, and comprises a support frame, an egg conveying line and N groups of protection units, each protection unit comprises a connecting piece, a fixing piece and two protection covers arranged up and down; the protective cover is provided with a tail end and a head end extending outwards, the tail end of the protective cover on the front side is matched with the head end of the protective cover on the rear side, the N sets of protective units are arranged on the outer side of the egg conveying line to form a closed conveying environment, the upper protective cover and the lower protective cover are tightly matched, and therefore the egg conveying efficiency is improved. The two front and back adjacent protective covers are connected through the locking bolts, direct contact between external hot air or cold air and eggs is effectively blocked, the suitable environment of the eggs in the conveying process can be effectively maintained, damage to the eggs caused by external adverse climate factors is reduced, and therefore the deterioration speed of the eggs is delayed, and the storage time of the eggs is prolonged; and the economic loss caused by egg deterioration is reduced.
