The utility model discloses a massage mechanism running track structure of convertible massage bed or chair, and the front end of electric massage mechanism is equipped with running gear, and running gear is installed on the gear strip to make electric massage mechanism can reciprocating operation, and the bottom of the rear end of electric massage mechanism is installed with upper guide pulley, and the flexible guide rail is the flexible metal strip or plastic strip, and is installed below the gear strip, and the both sides of guide pulley frame are installed with lower guide pulley, and the upper guide pulley of electric massage mechanism is through the lower guide pulley cooperation of guide pulley frame and installs the flexible guide rail, makes it when running not deviate, and angle adjusting mechanism is adjusted into massage bed mode or massage chair mode through controller, the utility model discloses realized massage bed or massage chair in electric adjusting backrest angle's time not to influence electric massage mechanism operation, can lie down massage and can sit and massage, greatly promote user use experience, adapt to more use scene simultaneously, and one thing two use cost performance is higher, and the production cost is low, and it is favorable to the popularization and application.

The invention discloses an automatic addressing method and system for distributed battery management units, and the method comprises the steps: carrying out data interaction between a main monitoring unit and all battery management units through a serial communication bus, and obtaining a battery sampling signal; the main monitoring unit determines address information of the first battery management unit; the method comprises the following steps: starting from a first battery management unit, simulating '0' and '1' logics by controlling the duty ratio of high and low levels of an IO signal line, sending an addressing message containing address information to a next battery management unit, and taking the address information of the message as the address of the battery management unit after the battery management unit correctly analyzes the received addressing message. And the battery management unit addresses the next battery management unit and sends an addressing message containing address information of the next battery management unit, so that automatic addressing of all the management units in sequence is realized. The method has the advantages that the addressing operation and the communication service are decoupled, the addressing range is wide, the requirement for the peripheral equipment of the MCU chip of the battery management unit is low, and the expandability is high.

The utility model provides a heat exchanger shunting device which solves the problems that a small-diameter radiating pipe is prone to scaling in the using process, the flow speed of fluid is affected, the heat exchange efficiency is reduced, frequent shutdown for cleaning and maintenance is needed, and equipment operation is affected. The double-flow-path reverse flow path is arranged to form two-time cross heat exchange with shell pass fluid, the heat exchange efficiency can be improved, the two flow channels are independent of each other, starting and stopping of the two flow channels can be freely adjusted according to the temperature requirement, energy is saved, meanwhile, single-side mechanical cleaning is allowed under the condition that operation is not stopped, and the heat exchange efficiency is improved. And the other side is maintained to operate, so that the downtime is reduced, the problem of scaling can be solved on the premise of not changing the pipe diameter and energy consumption, and meanwhile, the operation of equipment is not influenced.
