Circuit switch structure and detection system adopting same

Abstract

The invention discloses a circuit switch structure and a detection system adopting the same. The circuit switch structure comprises a first contact, a second contact and a hoop member, the hoop memberis provided with a fracture, two inner side surfaces of the fracture are respectively a first section and a second section, the first contact is fixedly connected with the first section, the second contact is fixedly connected with the second section, the first contact and the second contact are both metal contacts, the first contact abuts against the second contact, the first contact is connected with the hoop member in an insulating mode, and the second contact is connected with the hoop member in an insulating mode; the hoop member is hooped on a battery, before the battery expands, the first contact and the second contact are kept in abutting connection, and the first contact and the second contact are electrically connected with a detection circuit; when the battery is physically damaged, for example, the diameter is increased when the battery is expanded, the battery opens the hoop member, the first contact and the second contact are separated and disconnected, and the detectionsystem judges whether the battery is physically damaged such as expansion by detecting the circuit switch structure.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a circuit switch structure and a detection system adopting the structure. Background technique [0002] The circuit switch structure includes a normally open contact and a normally closed contact. Taking the normally closed contact as an example, the normally closed contact is a contact that is usually in a closed state. The contact is the contact point that connects the circuit in the circuit. Typical contacts include push button switches, knife switches, relays, etc. [0003] In the field of battery safety status detection, the detection circuit is usually directly connected to the two poles of the battery to detect the battery voltage, current and other parameters, and judge whether the battery is working normally according to the battery voltage and current, but the battery is not physically damaged. Usually there will be no abnormality in most cases. In most cases, abnorm...

Problems solved by technology

[0003] In the field of battery safety status detection, the detection circuit is usually directly connected to the two poles of the battery to detect the battery voltage, current and other parameters, and judge whether the battery is working normally according to the battery voltage and current, but the battery is not physically damaged. Usually there will be no abnormality in most cases. In most cases, abnormal operation occurs after the battery is physically damaged, such as the battery is squeezed and deformed, high temperature expansion, etc. However, the detection circuit in the prior art cannot detect whether the battery is There is physical damage, and it is impossible to judge whether the battery is abnormal due to physical damage
