This utility model discloses a cell balancing system, including a balancing module and a balancing control module. The balancing module includes multiple independently configured isolated power supply units and power supply units that supply power to each isolated power supply unit. Each cell in the cell pack is equipped with an isolated power supply unit, and each isolated power supply unit is connected to a balancing control module. The balancing control module sends independent balancing control signals to each isolated power supply unit. Under the control of the balancing control module, each isolated power supply unit starts or stops charging its corresponding cell, thereby achieving capacity balancing among the cells in the cell pack. The cell pack includes multiple cells connected in series, and the cell pack forms a loop with a bidirectional inverter to achieve charging and discharging operations with the power grid through the bidirectional inverter. The cells are lithium iron phosphate batteries. This utility model can achieve efficient balancing of the cells in the cell pack, with no limit on the number of cells to be balanced, low cost, and is suitable for widespread application.

The utility model discloses a filter support, including fixed frame, two active elements, two driven module and transmission part. Active element and driven module all are opposite fixed frame mobile setting, and transmission part is opposite fixed frame rotation setting. Two active elements and two driven module are along annular arrangement, and a driven module is located between two active elements. Active element and transmission part transmission connection, and driven module also with transmission part transmission connection. When active element is opposite fixed frame mobile, can drive transmission part opposite fixed frame rotation, and then promotes driven module to move to the same mobile direction with active element. The structure realizes the cooperation of active element and driven module through transmission part, improves the adjustment flexibility, can better adapt to different caliber lens, reduces the dark corner, satisfies the diversified shooting demand.

This invention provides a bottom-intake air-cooled battery pack structure, belonging to the technical field of cell module heat dissipation. The bottom-intake air-cooled battery pack structure includes a housing, cell modules, an air inlet, and an air outlet. The cell modules are arranged in multiple rows within the housing. The air inlets are located at the bottom of the housing and are used for air intake within the housing. The air outlet is located on the front side of the housing. The top of the housing is divided into confluence spaces connecting the various cell modules, and the air outlet connects to these confluence spaces at the top of the housing for exhaust. This invention solves the problem of uniform air intake temperature for multi-row cell modules, provides good air cooling performance, and is not limited by the number of cell modules.
