Background
The power battery is used as the most basic and most core element for forming the new energy automobile, and the performance of the power battery directly influences the new energy automobile. The research shows that: the performance of the power battery changes along with the change of temperature; under the environment of lower than 0 ℃, the charge-discharge multiplying power and the capacity of the battery are limited, the requirements of users cannot be met, and the lithium is separated from the battery cell to cause short circuit in the battery when the battery works at low temperature for a long time or for multiple times; in an environment with the temperature higher than 45 ℃, active substances in the battery are reduced, so that the service life of the battery core is shortened, and even thermal runaway can be caused under an extreme working condition. It is necessary to monitor the temperature of the battery cell in order to ensure that the battery has good charge and discharge performance and longer service life. The square battery has a regular structure, and only a certain space needs to be reserved for the square battery when the temperature is arranged, and the temperature can be placed in the square battery. The outer wall of the cylindrical battery is a cylindrical surface, and the temperature is difficult to fix on the arc surface. When a power battery system is composed of a plurality of battery cells, the performance of the power battery system is determined by the battery cell with the worst performance in the system, so the consistency of the battery cells composing the power battery system is high. Therefore, the temperature sensor for collecting the cylindrical battery core is required to be placed at a fixed position, so that the consistency of the collected data of the battery can be ensured.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a fixing device of cylinder electricity core temperature sensing can be fixed in a fixed position of cylinder electricity core with temperature sensor, guarantees battery data collection's uniformity.
The technical scheme of the utility model is that:
the utility model provides a fixing device of cylinder electricity core temperature, is including axial positioning pole, be fixed in one of axial positioning pole and serve cylinder electricity core anchor clamps and set up in one of axial positioning pole and serve the temperature sensing draw-in groove, cylinder electricity core anchor clamps thereby including two arc splint, thereby the inner of two arc splint all is fixed in axial positioning pole one and serves and form C shape cardboard structure, the temperature sensing draw-in groove be located between the inner of two arc splint and the notch of temperature sensing draw-in groove towards the notch of C shape cardboard.
And the clamping surfaces of the two arc-shaped clamping plates are provided with adhesive layers.
And an adhesive layer is arranged on the inner groove surface of the temperature-sensing clamping groove.
The axial positioning rod is of a square rod-shaped structure, the temperature sensing clamping groove is formed in one side face of the axial positioning rod, the inner ends of the two arc-shaped clamping plates are connected to the two opposite side faces of the axial positioning rod respectively, and the side face, provided with the temperature sensing clamping groove, of the axial positioning rod is located between the two side faces of the axial positioning rod for fixing the arc-shaped clamping plates.
The utility model has the advantages that:
the utility model discloses be provided with the axial positioning pole, be provided with cylinder electricity core anchor clamps and temperature sensing draw-in groove on one end of axial positioning pole, when fixed temperature sensing, be fixed in the module box of battery module with the other end of axial positioning pole, because the length of axial positioning pole is the definite value, can fix a position the axial position of temperature sensing, and because the relative position of module box for the cylinder electricity core that awaits measuring is definite, so the circumferential position of temperature sensing also can confirm, so pass through the utility model discloses can fix temperature sensor in a fixed position of cylinder electricity core, guarantee the uniformity of battery data collection; the utility model discloses a all be provided with the bonding glue film on the clamping face of two arc splint and the inner groove face of temperature sensing draw-in groove, guaranteed the fixed stability of temperature sensor.
