Problems solved by technology

[0002] When the battery is in use or charging, it is often prone to bulging or overheating. Because of this situation, it often happens on the battery, and the battery is placed in a remote place when it is in use, so this causes the battery to bulge or overheat. It was found that some existing bulging or overheated battery detection mechanisms are very complicated, and their use and promotion are difficult and not applicable

specific Embodiment 1

[0022] Such as figure 1 As shown, the present invention discloses a battery overheating detector, which includes a detection body 1 with a cavity, and an elastic middle layer 4 is arranged inside the detection body 1, and the middle layer 4 separates the detector body into upper and lower parts. The chamber 2 and the lower chamber 3 are sealed with inflation gas in the lower chamber 3. The expansion coefficient of the inflation gas is greater than that of the gas in the upper chamber 2. The upper chamber 2 is provided with two opposite electrodes 5, wherein One electrode 5 is disposed on the middle layer 4 , and the thermal expansion of the lower chamber 3 makes the two electrodes 5 electrically connected. The lower side wall of the lower chamber 3 is flat and elastic. The lower chamber 3 is provided with a support column 6 ; the support column 6 is in close contact with the lower side wall of the lower chamber 3 , and the support column 6 is used to push the middle layer 4 a...

Abstract

The invention discloses a battery overheat detector. The detector comprises a detection body with a cavity, the detection body is internally provided with an elastic intermediate layer, the intermediate layer divides the detection body into an upper cavity and a lower cavity, expansion gas is sealed in the lower cavity, the expansion coefficient of the expansion gas is greater than that of a gas in the upper cavity, two electrodes opposite to each other are arranged in the upper cavity, one electrode is arranged in the intermediate layer, and the two electrodes are electrically connected when the lower cavity is thermally expanded. The battery overheat detector has the advantages that after the battery is heated, the expansion gas is expanded so that the two electrodes of the detector are connected, other conductive components are cooperated, so that overheat of the battery can be detected effectively, help is provided for real-time monitoring of the battery, a swelling condition of the battery detected, the cost is low, use is convenient, the detector is easier to popularize and simple in structure rapid detection for the battery can be ensured, the detector can be mounted on the battery, and the practicality is high.

Description

technical field [0001] The invention relates to a battery overheating detector. Background technique [0002] When the battery is in use or charging, it is often prone to bulging or overheating. Because of this situation, it often happens on the battery, and the battery is placed in a remote place when it is in use, so this causes the battery to bulge or overheat. It was found that some existing bulging or overheated battery detection mechanisms are very complicated, and their use and promotion are difficult, and they are not applicable. Contents of the invention [0003] The purpose of the present invention is to provide a battery overheating detector for the above existing problems, which can easily detect the battery, and can cooperate with other mechanisms to ensure the safety of the battery, and ensure that the battery can be detected in time when it fails, and can be processed in time. Moreover, the cost is low, the use is convenient, and it can be more easily popul...
