Description

Technical Field

[0001] This utility model relates to the field of battery monitoring technology, and in particular to a battery status monitoring and temperature abnormality alarm device. Background Technology

[0002] With the rapid development of the new energy vehicle industry, the operating status of the power battery, as the core power source, directly determines the vehicle's range, safety, and lifespan. New energy vehicle power batteries generate heat during charging and discharging, especially during fast charging, high-load driving (such as climbing hills or high-speed cruising), or low-temperature environments. Heat can easily accumulate inside the battery, and if the temperature exceeds the safety threshold (usually 60-65℃), it can easily cause battery bulging, electrolyte leakage, and in severe cases, even thermal runaway, leading to fires, explosions, and other safety accidents. However, current battery temperature monitoring systems are integrated into the vehicle's built-in Battery Management System (BMS), but these systems primarily monitor the overall temperature of the battery pack and are not accurate enough in responding to localized temperature anomalies in individual cells. Therefore, we are introducing a battery status monitoring and temperature anomaly alarm device. Utility Model Content

[0003] The main purpose of this invention is to provide a battery status monitoring and temperature abnormality alarm device, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A battery status monitoring and temperature abnormality alarm device includes a U-shaped plate. The U-shaped plate has an internal and external through mounting hole in the middle of its right end. A rubber ring is fixedly sleeved in the mounting hole. There are movable holes at the four corners of the right end of the U-shaped plate. A buffer component is movably sleeved in the four movable holes. A monitoring component is movably sleeved in the rubber ring. An alarm component is fixedly connected to the upper end of the U-shaped plate.

[0005] Preferably, the monitoring component includes a thermal sensor, an arc-shaped clamping head, and a screw. Two thermal sensors and two screws are provided, and they are arranged in a front-to-back mirror distribution. Rubber pads are fixedly connected to the inner wall surfaces of the two arc-shaped clamping heads, and return springs are fixedly connected to the outer surfaces of the two arc-shaped clamping heads. The outer sides of the two return springs are fixedly connected to the front inner wall surface and the rear inner wall surface of the U-shaped plate, respectively. Anti-slip knobs are fixedly connected to the outer sides of the two screws.

[0006] By adopting the above technical solution: the thermistor model: NTC 10KΩ B3950 (negative temperature coefficient thermistor), it is possible to quickly capture changes in battery temperature.

[0007] Preferably, the buffer assembly includes a fixed plate, with a through hole in the middle of the left end of the fixed plate, an adhesive layer fixedly connected to the right edge of the fixed plate, movable rods fixedly connected to the four corners of the left end of the fixed plate, and several buffer corrugated pipes fixedly connected to the upper and lower parts of the left end of the fixed plate.

[0008] By adopting the above technical solution: the adhesive layer facilitates the quick fixation of the fixing plate to the battery mounting surface, the sleeve hole provides an installation channel for the thermal sensor probe, and the movable rod cooperates with the buffer bellows to absorb the bumps of the car driving, prevent vibration from being transmitted to the monitoring components, and ensure the fixation and shock resistance of the buffer assembly.

[0009] Preferably, the left ends of several of the buffer bellows are fixedly connected to the right end of the U-shaped plate, and the left parts of the four movable rods are respectively movably sleeved in the corresponding four movable holes.

[0010] By adopting the above technical solution: the buffer corrugated pipe connects the fixed plate and the U-shaped plate, which can absorb vibration energy through expansion and contraction deformation. The movable rod slides in the movable hole, limiting the relative displacement between the U-shaped plate and the fixed plate. The two work together to improve the overall seismic resistance of the device and avoid vibration affecting the monitoring accuracy.

[0011] Preferably, the thermal sensor is located between two rubber pads, and the right side of the thermal sensor is movably sleeved inside the rubber ring, while the probe of the thermal sensor is movably sleeved inside the sleeve hole.

[0012] By adopting the above technical solution: the rubber pad clamps the thermal sensor to ensure its stable position, the rubber ring provides buffer protection for the right side of the thermal sensor, and the thermal sensor probe is close to the battery through the sleeve hole, ensuring that the thermal sensor can accurately collect battery temperature data and improve monitoring accuracy.

[0013] Preferably, the inner sides of the two screws are threaded to the front and rear ends of the U-shaped plate, respectively. The outer surfaces of the two arc-shaped clamping heads are each provided with guide holes. The portions of the two screws that are close to each other are respectively movably sleeved in the corresponding two guide holes. The two screws are respectively located in the corresponding two return springs.

[0014] By adopting the above technical solution: the screw is threadedly connected to the U-shaped plate to ensure stable adjustment; the guide hole provides guidance for the movement of the screw and avoids the displacement of the arc-shaped clamping head; the screw is located inside the return spring to limit the spring and prevent the return spring from deforming and shifting, thus ensuring the stability and reliability of the adjustment of the monitoring component.

[0015] Preferably, the alarm component includes a mounting box, the left end of which has a through-hole for wires, a controller is fixedly mounted on the lower inner wall of the mounting box, a buzzer is fixedly mounted on the upper left side of the mounting box, a strobe light is fixedly mounted on the upper right side of the mounting box, and the lower end of the mounting box is fixedly connected to the upper end of the U-shaped plate.

[0016] By adopting the above technical solution: controller model: STM32F030C8T6 (ARM Cortex-M0 core microcontroller), it can stably receive and process thermal sensor signals quickly, and can simultaneously drive the buzzer and strobe light, accurately triggering alarms when the temperature is abnormal. Buzzer model: TMB12A05 (passive piezoelectric buzzer), which can clearly transmit alarm sounds in the noise environment of a car driving. When used with the controller trigger signal, it can promptly remind the driver of abnormal battery temperature in the form of sound, and the alarm has high recognition. The strobe light model is LTE-1082 (red LED strobe light). It uses a high-brightness red LED, which has a strong visual warning effect and is easily noticed by the driver even in bright light. It forms a "dual alarm" with the buzzer, which can quickly attract the driver's attention and prevent the driver from missing the abnormal temperature warning due to not hearing the sound, thus improving the reliability of the alarm.

[0017] Compared with the prior art, the present invention has the following beneficial effects: In this invention, the adhesive layer of the buffer component can be quickly fixed to the designated mounting surface of the battery. The movable rod and movable hole cooperate, and the buffer bellows can absorb the bumps of the car and avoid the impact of vibration. In the monitoring component, rotating the anti-slip knob drives the screw to move, and the distance between the arc-shaped clamping heads can be adjusted with the help of the return spring to adapt to thermistors of different sizes and fix them, improving the stability of thermistors during use. The rubber pad clamps the thermistor to ensure that its probe is close to the battery, ensuring accurate monitoring. The controller of the alarm component receives the signal from the thermistor and triggers the buzzer and flashing light to provide timely alarm when the temperature is abnormal. The entire device is easy to install, highly adaptable, can monitor the battery temperature in real time and accurately, effectively prevent safety risks caused by abnormal temperature, and has good shock resistance and can operate stably for a long time, providing reliable protection for the safety of power batteries in new energy vehicles.

[0023] Please see Figure 1-6This utility model provides a technical solution: A battery status monitoring and temperature abnormality alarm device includes a U-shaped plate 1. A through mounting hole 2 is opened in the middle of the right end of the U-shaped plate 1. A rubber ring 3 is fixedly sleeved in the mounting hole 2. Movable holes 4 are opened at the four corners of the right end of the U-shaped plate 1. A buffer component 5 is movably sleeved in the four movable holes 4.

[0024] In this embodiment, the monitoring component 6 includes a thermal sensor 61, an arc-shaped clamping head 62, and a screw 63. Two thermal sensors 61 and two screws 63 are provided, and they are arranged in a front-to-back mirror distribution. Rubber pads 64 are fixedly connected to the inner walls of both arc-shaped clamping heads 62, and return springs 66 are fixedly connected to the outer surfaces of both arc-shaped clamping heads 62. The outer surfaces of the two return springs 66 are fixedly connected to the front and rear inner walls of the U-shaped plate 1, respectively. Two screws... Anti-slip knobs 65 are fixedly connected to the outer surfaces of the 63; the buffer assembly 5 includes a fixing plate 51, with a through hole 52 in the middle of the left end of the fixing plate 51, an adhesive layer 53 fixedly connected to the right edge of the fixing plate 51, movable rods 54 fixedly connected to the four corners of the left end of the fixing plate 51, and several buffer corrugated tubes 55 fixedly connected to the upper and lower parts of the left end of the fixing plate 51; the left ends of the several buffer corrugated tubes 55 are fixedly connected to the right end of the U-shaped plate 1. Next, the left parts of the four movable rods 54 are respectively movably sleeved in the corresponding four movable holes 4; the thermal sensor 61 is located between the two rubber pads 64, and the right part of the thermal sensor 61 is movably sleeved in the rubber ring 3, and the probe of the thermal sensor 61 is movably sleeved in the sleeve hole 52; the inner sides of the two screws 63 are respectively threaded to the front and rear ends of the U-shaped plate 1, and the outer surfaces of the two arc-shaped clamping heads 62 are each opened with guide holes, and the parts of the two screws 63 that are close to each other are respectively movably sleeved in the corresponding two guide holes, and the two screws 63 are respectively located in the corresponding two return springs 66; the alarm assembly 7 includes a mounting box 71, the left end of the mounting box 71 has a wire hole 72 that passes through inside and outside, the lower inner wall of the mounting box 71 is fixedly installed with a controller 73, the upper left part of the mounting box 71 is fixedly installed with a buzzer 74, the upper right part of the mounting box 71 is fixedly installed with a flashing light 75, and the lower end of the mounting box 71 is fixedly connected to the upper end of the U-shaped plate 1.

[0025] It should be noted that this utility model is a battery status monitoring and temperature abnormality alarm device. In use, peel off the protective film of the adhesive layer 53 at the right edge of the fixing plate 51, attach the fixing plate 51 to the designated mounting surface of the battery, and press the fixing plate 51 to ensure the adhesive layer 53 is firmly bonded. At this time, the movable rods 54 at the four corners of the left end of the fixing plate 51 are respectively located in the movable holes 4 at the four corners of the right end of the U-shaped plate 1. Several buffer bellows 55 at the left end of the fixing plate 51 are in their natural state. Then, rotate the anti-slip knobs 65 on the outer side of the two screws 63, causing the screws 63 to move threadedly at the front and rear ends of the U-shaped plate 1. The ends of the screws 63 that are close to each other are in the arc-shaped clamp. Slide the guide hole of the holding head 62 to push the two arc-shaped clamping heads 62 closer or further apart against the elastic force of the return spring 66. Place the thermal sensor 61 between the rubber pads 64 on the inner wall of the two arc-shaped clamping heads 62. Adjust the thermal sensor 61 so that the right part passes through the rubber ring 3 in the mounting hole 2 at the right end of the U-shaped plate 1, and the probe of the thermal sensor 61 is movably sleeved in the sleeve hole 52 at the left end of the fixing plate 51 and close to the battery surface. Then rotate the anti-slip knob 65 in the opposite direction. The return spring 66 rebounds and drives the arc-shaped clamping heads 62 to return to their original position. The rubber pads 64 clamp the thermal sensor 61. After that, pass the power cord of the thermal sensor 61 through the mounting box in the alarm assembly 7. The wire hole 72 at the left end of 71 connects to the controller 73 inside the mounting box 71. Simultaneously, ensure that the buzzer 74, strobe light 75, and controller 73 are electrically connected. After the car starts, the controller 73 is powered on, and the thermal sensor 61 begins real-time monitoring of the battery temperature. The monitoring data is transmitted to the controller 73 via the power cord, and the device enters normal monitoring mode. Bumps generated during vehicle operation are transmitted through the fixing plate 51 to the buffer bellows 55. The buffer bellows 55 expands and contracts to absorb vibration energy. Simultaneously, the movable rod 54 slides slightly within the movable hole 4. Combined with the elasticity of the rubber ring 3, this prevents vibration from affecting the monitoring accuracy of the thermal sensor 61. When the thermal sensor 6... When the battery temperature exceeds the set threshold, an abnormal temperature signal is transmitted to the controller 73. The controller 73 immediately triggers the alarm component 7, and the buzzer 74 on the upper left of the mounting box 71 emits a high-decibel alarm sound, while the strobe light 75 on the upper right flashes simultaneously to remind the driver of the abnormal battery temperature. After the driver notices the alarm, he should stop the vehicle in a safe area in time and turn off the vehicle's high-voltage power supply to reduce the battery temperature. Once the battery temperature drops to a safe range, the thermal sensor 61 transmits a normal temperature signal to the controller 73, and the controller 73 automatically stops the alarms of the buzzer 74 and the strobe light 75. The device resumes normal monitoring and continues to monitor the battery status in real time.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
