Abstract
Description
Technical Field
[0001] This utility model belongs to the field of temperature sensor technology, specifically relating to a wire-based short-circuit protection temperature sensor for energy storage batteries. Background Technology
[0002] With the rapid development of new energy storage systems, the requirements for temperature monitoring accuracy of energy storage devices such as lithium-ion batteries are increasing. However, traditional temperature sensors are prone to short circuits under complex operating conditions due to wire wear, compression, or aging, leading to measurement failures or even safety hazards. Especially in application scenarios with frequent vibrations and tight spaces, such as vehicle batteries and grid energy storage, existing sensors generally have problems such as insufficient mechanical strength of the insulation layer and easy loosening of the joints. In recent years, the industry has improved reliability by improving the wire armor structure and adopting self-resetting fuse materials, but it still needs to meet the dual requirements of high-precision temperature measurement and short-circuit protection.
[0003] Traditional sensors often use ordinary PVC or silicone insulated wires, which are prone to insulation damage due to long-term vibration and friction within the confined space of a battery pack. In high-temperature environments, the insulation material is susceptible to aging and cracking, and exposed metal wires can cause short circuits when in contact with the battery casing or electrodes. This can lead to temperature measurement failure or, in severe cases, trigger battery thermal runaway. Existing short-circuit protection solutions, such as adding a metal braided mesh sheath, sacrifice flexibility, while adding fuses results in response delays. Furthermore, most solutions do not address the waterproofing and dustproofing issues at the connection between the wire and the sensor body. In addition, the high cost of specialized wires makes widespread adoption difficult, necessitating a new short-circuit protection technology that balances reliability, economy, and installation adaptability. Therefore, a wire-based short-circuit protected temperature sensor for energy storage batteries has emerged. Summary of the Invention

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example
[0018] Reference Figures 1-6 This is an embodiment of the present invention, which provides a wire-based short-circuit protection temperature sensor for energy storage batteries, comprising: The housing 101, the fixing plate 102 fixedly installed on the outer wall of the housing 101, the cover plate 103 movably connected to the side wall of the housing 101, the heat dissipation vent 104 opened on the side wall of the housing 101, the shock absorption assembly 105 provided at the bottom of the housing 101, the battery plate 106 fixedly installed on the surface of the shock absorption assembly 105, the aluminum plate 107 attached to the surface of the battery plate 106, the sensor 108 fixedly connected to the surface of the aluminum plate 107, the short circuit protection assembly 109 fixedly connected to the side wall of the sensor 108, the opening and closing assembly 110 fixedly installed on the surface of the cover plate 103, the dustproof plate 111 fixedly installed on the inner wall of the cover plate 103, the fan 112 adapted to be installed on the surface of the dustproof plate 111, and the heat sink 113 fixedly installed on the inner wall of the housing 101; The shock absorption assembly 105 includes a connecting block 105a fixedly installed on the inner wall of the housing 101, a first buffer barrel 105b movably connected to the inner wall of the connecting block 105a, a first spring 105c disposed in the inner cavity of the first buffer barrel 105b, a pull rod 105d slidably connected to the inner wall of the first buffer barrel 105b, a mounting block 105e movably connected to the end of the pull rod 105d, a pressure rod 105f fixedly installed at the bottom of the mounting block 105e, a second buffer barrel 105g fixedly installed at the bottom of the housing 101, and a second spring 105h disposed in the inner cavity of the second buffer barrel 105g.
[0019] When the fan 112 is turned on, the dustproof plate 111 reduces the entry of dust, and the air circulates in the inner cavity of the housing 101, passing through the heat sink plate and expelling heat through the heat dissipation port 104 to achieve the heat dissipation effect.
[0020] Specifically, one end of the first spring 105c is fixedly connected to the side wall of the first buffer tank 105b, and the other end is fixedly connected to the end of the pull rod 105d. The pressure rod 105f is slidably connected to the inner wall of the second buffer tank 105g. One end of the second spring 105h is fixedly connected to the bottom of the housing 101, and the other end is fixedly connected to the end of the pressure rod 105f.
[0021] When the mounting block 105e is pressed down, the mounting block 105e presses the pressure rod 105f, the pressure rod 105f presses the second spring 105h, the mounting block 105e pulls the pull rod 105d, the pull rod 105d pulls the first spring 105c, which in turn pulls the mounting block 105e. The first spring 105c and the second spring 105h cooperate with each other to achieve the positioning of the mounting block 105e and the effect of double shock absorption.
[0022] Furthermore, the short-circuit protection assembly 109 includes a terminal block 109a fixedly installed on the side wall of the sensor 108, a wire clip 109b fixedly installed on the surface of the aluminum plate 107, a wire 109c fixedly connected to the inner wall of the terminal block 109a, and a threaded tube 109d sleeved on the surface of the wire 109c.
[0023] Among them, the threaded tube 109d is arranged in sections suspended on the side wall of the wire clamp 109b to prevent short circuit of the wire 109c, and the wire clamp 109b fixes the wire 109c in sections to prevent the problem of the rubber of the wire 109c from breaking.
[0024] Preferably, the opening and closing assembly 110 includes a hinge 110a fixedly installed on the side wall of the housing 101, a slider 110b fixedly connected to the surface of the hinge 110a, a guide rail 110c slidably connected to the inner wall of the slider 110b, a pull plate 110d fixedly installed at the end of the guide rail 110c, a crank 110e movably connected to the inner wall of the pull plate 110d, a shaft plate 110f fixedly connected to the side wall of the housing 101, and a spring telescopic rod 110g movably connected to the surface of the shaft plate 110f.
[0025] It should be noted that the middle part of the crank 110e is movably connected to the shaft on the surface of the shaft plate 110f. When the cover plate 103 is opened, the cover plate 103 pulls the crank 110e to rotate with the hinge 110a. The slide rail slides on the inner wall of the slider 110b. The rotation of the crank 110e drives the guide rail 110c and the cover plate 103 to achieve up and down flipping motion. In addition, the shaft at the end of the crank 110e is equipped with a self-locking spring telescopic rod 110g, which can limit the cover plate 103.
[0026] In use, the fan 112 is turned on, and the dustproof plate 111 reduces the entry of dust. The air circulates in the inner cavity of the housing 101, and the heat is discharged through the heat sink 104 to achieve the effect of heat dissipation. When the mounting block 105e is pressed down, the mounting block 105e presses the pressure rod 105f, the pressure rod 105f presses the second spring 105h, the mounting block 105e pulls the pull rod 105d, the pull rod 105d pulls the first spring 105c, and thus pulls the mounting block 105e. The first spring 105c and the second spring 105h cooperate with each other to achieve the positioning of the mounting block 105e and double shock absorption. The effect is that the threaded tube 109d is suspended in sections on the side wall of the wire clamp 109b to prevent short circuit of the wire 109c. The wire clamp 109b fixes the wire 109c in sections to prevent the problem of the rubber of the wire 109c breaking. When the cover plate 103 is opened, the cover plate 103 pulls the crank 110e to rotate with the hinge 110a. The slide rail slides on the inner wall of the slider 110b. The rotation of the crank 110e drives the guide rail 110c and the cover plate 103 to achieve up and down flipping movement. In addition, the shaft at the end of the crank 110e is equipped with a self-locking spring telescopic rod 110g, which can limit the cover plate 103.
[0027] In summary, the fan 112 and heat sink 113 effectively dissipate the heat generated by the battery panel 106 and sensor 108 during operation; the short-circuit protection component 109 effectively prevents the problem of broken rubber on the wire 109c and the short circuit caused by broken rubber on the wire 109c; and the opening and closing component 110 effectively solves the problem of inconvenient operation when maintaining the sensor 108. The device is simple and efficient to operate, and effectively solves the problems of traditional temperature sensors 108 not being able to protect the wire 109c and not being able to provide safer and more stable temperature monitoring for energy storage batteries.
