Problems solved by technology

[0005] In order to make up for the deficiencies of the existing technology, to solve the temperature detection of the battery cell in the prior art, the temperature sensor needs to be fixed on the outer wall of the battery cell for direct measurement, but the temperature sensor is usually fixed with the battery cell by bonding and a special bracket, and the bonding connection is It is easy to fall off during the vibration process, and the use of special buckles is easy to occupy too much volume, which is not conducive to the efficient combination of batteries and increases the volume of battery products. A thermal sensor proposed by the invention

Embodiment approach

[0022]As an embodiment of the present invention, the bottom of the No. 1 hole 12 is provided with a chute 17 perpendicular to the No. 2 hole 16, and a slider 18 is slidably connected to the chute 17. The slider 18 is close to the bottom of the chute 17. One end is arranged in a wedge shape, and the slider 18 is pressed against the elastic rod 14 to further increase the fit between the probe 15 and the battery cell and increase the detection accuracy of the sensor; when the sensor body 13 is inserted into the No. 1 hole 12, the sensor body 13 drives the elastic The rod 14 and the probe 15 slide down, so that the probe 15 slides down and is embedded in the second hole 16, so that the probe 15 is in contact with the outer wall of the cell clamped in the arc-shaped groove 11, so as to detect the real-time temperature of the cell normally. At the same time, due to the elastic force of the elastic rod 14, the probe 15 is close to the outer wall of the cell, but when the elastic rod 1...

Abstract

The invention belongs to the technical field of sensors, specifically a heat-sensitive sensor, comprising a shell with an X-shaped cross section, arc-shaped grooves for fixing cylindrical electric cores are provided on both sides of the shell; a hole is opened in the shell, There is a sensor body in the No. 1 hole, and the end of the sensor body close to the bottom of the No. 1 hole is fixedly connected to the probe through an elastic rod; the No. The hole is in contact with the surface of the battery core; the invention uses the shell with an X-shaped cross-section to effectively isolate and fix the adjacent battery cores while serving as a fixing frame for the sensor, reducing the volume occupied by the special bracket, and at the same time Adjacent batteries are isolated to maintain a good heat dissipation gap, reduce collision friction between adjacent batteries, and further extend the service life of batteries.

Description

technical field [0001] The invention belongs to the technical field of sensors, in particular to a thermosensitive sensor. Background technique [0002] As a new type of clean and renewable secondary energy, lithium battery has the advantages of high working voltage, high energy density and light weight, and has been widely used in mobile phones, notebook computers, electric vehicles and other fields. Lithium-ion batteries are affected by Joule heat, reaction heat, and polarization heat during the discharge process. There will be a large amount of heat accumulation, which will increase the battery temperature, affect battery life and cycle efficiency, and cause serious explosions. In the event of a short circuit or overshoot inside, it may also cause an explosion due to excessive temperature. Therefore, it is necessary to effectively monitor the heat generation of lithium batteries to eliminate potential safety hazards. At present, the most direct and effective temperature...
