Description

Technical Field

[0001] This utility model relates to the field of temperature and pressure sensor technology, and more specifically, to a temperature and pressure sensor for measuring water circulation. Background Technology

[0002] Water temperature and pressure sensors are specifically designed for measuring temperature and pressure changes in water circulation pipelines. They can be widely used in applications such as battery cooling and energy storage in new energy vehicles. A typical temperature and pressure sensor consists of two parts: a pressure sensor and a temperature sensor. The pressure sensor usually employs microelectronics technology, using surface micromachining to fabricate the sensing element, and measures pressure by utilizing changes in the electrical properties of the sensing element. The temperature sensor may use principles such as thermistors or thermocouples, generating a corresponding electrical signal by measuring temperature. These sensors are typically mounted on the circulation pipeline using a mounting bracket. An NTC or other temperature-sensitive element probe extends into the pipeline to detect the water temperature circulating in the pipeline; pressure enters the sensor through a small orifice, applying pressure to the pressure sensing element. The pressure sensing element converts the pressure signal into an electrical signal, which is then processed by a signal conditioning chip to output a voltage signal linearly related to the pressure. This invention's sensor can integrate the two measurement systems into a single unit through electronic circuitry, enabling simultaneous transmission of temperature and pressure data to the control system.

[0003] In existing technologies, temperature and pressure sensors used to measure water circulation in new energy vehicles and energy storage systems typically employ stainless steel housings for long-term use in high-temperature, high-humidity, and salt-fog environments, but this is costly. Furthermore, during use, most sensors utilize threaded connections to the circulation pipeline, requiring tools for on-site installation. In manufacturing, the sensor housing and internal components are assembled using riveting, resulting in a complex production process. Therefore, we propose an improvement: a temperature and pressure sensor for measuring water circulation. Utility Model Content

[0032] The outer end of the snap ring body 4 is provided with a snap ring groove 11 and a snap ring hole. The snap ring groove 11 is horizontally embedded in the outer end of the snap ring body 4. The snap ring groove 11 and the snap ring hole are connected through each other. Both the snap ring groove 11 and the snap ring hole are connected through each other to the snap ring body 4.

[0033] The front end of the groove 12 is movably connected to the positioning end of the folding rod assembly 16, the slide 13 passes through the tail end of the groove 12, and the tail end of the positioning telescopic rod 14 is fixed to the tail end of the groove 12.

[0035] The linkage between the arc-shaped sliding plate and the arc-shaped sliding groove 13 facilitates the folding rod assembly 16 to easily fold and push the arc-shaped plate 17 to attach to the inside of the sensor housing 3 when the positioning telescopic rod 14 extends or retracts, thereby achieving positioning.
