Fixing protection mechanism for continuous adjustment of pressure on cylindrical lithium battery

Abstract

The invention discloses a cylindrical lithium battery pressure continuous adjustment fixed protection mechanism, which is used for fixing the lithium battery in the vibration experiment so as not to cause relative displacement with the working plane of the vibrating table, and to ensure good contact between the lithium battery and the charging and discharging electrodes without affecting Lithium battery charging and discharging process. The protection mechanism includes: a vertical fixing part and a horizontal fixing part; springs are installed at both ends of the vertical pressing plate in the vertical fixing part, and a screw rod passes through the spring and the vertical pressing plate. The other end of the screw rod is a movable nut connected with the stepping motor. When the mechanism is working, the nut rotates synchronously with the motor, and the program controls the forward or reverse rotation of the motor to make the horizontal platen rise or fall. The pressure sensor and temperature sensor are installed inside the pressure groove of the vertical pressure plate. The pressure sensor collects the pressure of the vertical pressure plate to the lithium battery in real time, and is used to program the continuous operation of the stepping motor, so as to ensure that the pressure on the lithium battery in the battery tank is constant. Within the range; the temperature sensor will collect the temperature data during the charging and discharging process of the battery in real time. The horizontal fixing part fixes the lithium battery in the horizontal direction through two horizontal pressing plates and the energized electrodes, and the energized current is provided by the electrodes.

Description

technical field [0001] The invention designs a cylindrical lithium battery pressure continuous adjustment fixed protection mechanism technical background [0002] The key to the vibration experiment is to ensure that there is no relative displacement between the experimental sample and the vibration plane. This requires the test sample to be placed on a certain fixed mechanism. While ensuring that no relative displacement occurs, the applied pressure must also be controlled within a certain range. The reason Because the test sample will be damaged if the pressure is too high, and the fixing effect will not be achieved if the pressure is too small. For the vibration experiment of cylindrical lithium batteries, it is even more necessary for the samples to be carried out in a certain energized environment. There are no products that can meet the above requirements for the existing fixing mechanisms on the market. Contents of the invention [0003] The purpose of the present ...
