Description

Technical Field

[0001] This utility model relates to the field of new energy vehicles, specifically a monitoring and early warning device for new energy batteries. Background Technology

[0002] With the rapid development of new energy battery technology, battery pack safety monitoring has become a crucial aspect of ensuring stable equipment operation. Temperature monitoring, as a core indicator, places stringent demands on the installation stability and reliability of monitoring equipment. Conventional new energy battery temperature monitoring equipment typically uses bolts for fastening. However, bolt fastening requires tools to align and tighten each bolt individually, making the assembly process cumbersome and necessitating improvement.

[0003] For example, Chinese patent application CN202420115148.9 discloses a new energy vehicle battery heat monitoring device, including a battery pack cover, a battery pack base below the battery pack cover, heat dissipation mesh on both the battery pack cover and the battery pack base, a battery module fixedly installed on the upper surface of the battery pack base, a cross-shaped partition fixedly installed on the upper surface of the battery pack base, a locking hole on the cross-shaped partition, a temperature detector on the cross-shaped partition, and a quick-release device on the temperature detector, the quick-release device including two hollow columns, both of which are sleeved on the inner surface of the temperature detector.

[0004] The aforementioned quick-assembly and disassembly device relies on the single-sided engagement of the ball inside the hollow column with the locking hole of the cross-shaped partition to achieve fixation. This single-point engagement structure has weak vibration resistance. In scenarios such as the operation of new energy vehicles, the equipment will be continuously subjected to vibration and impact. The contact area between the ball and the locking hole is prone to wear due to repeated friction, causing the engagement force to gradually weaken. With long-term use, the temperature detector may loosen or even fall off, affecting the stability and reliability of monitoring. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a monitoring and early warning device for a new energy battery, comprising a battery pack, a temperature monitor, and a fastening assembly consisting of a plug rod and a nut. Several limiting rods are rotatably mounted on the side wall of the plug rod via a rotating shaft. A push rod is slidably mounted at the center of the plug rod via an elastic member. The limiting rods are connected to the push rods so that the limiting rods rotate around the shaft when the push rods slide. A nut is threaded onto the outer wall of the plug rod. The temperature monitor is locked to the inner wall of the battery pack through the cooperation of the nut and the limiting rods.

[0007] Preferably, a cavity is provided at the center of the insertion rod, a lever is fixedly installed on the side wall of the rotating shaft, the lever and the limiting rod form an angle, and a pair of baffles are fixedly sleeved on the push rod at the cavity position, and a groove for accommodating the lever is formed between the pair of baffles.

[0008] Preferably, the insert rod has a plurality of grooves on the periphery of the cavity for accommodating the limiting rod, and the bottom wall of the groove has a through hole for the lever to pass through.

[0009] Preferably, a socket is provided on one side of the cavity, the elastic member is a spring embedded in the socket, the end of the push rod extends into the socket and contacts the spring, the rod body of the push rod is fixedly sleeved with a limiting sleeve, and when the spring is in a relaxed state, the limiting sleeve abuts against the push rod.

[0010] Preferably, one end of the push rod passes through the end face of the insert rod and is fixedly fitted with an anti-detachment cap.

[0011] Preferably, a pull ring is rotatably mounted on one end of the insertion rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This utility model utilizes a linkage design between a push rod and a limiting rod. Simply pressing the push rod retracts the limiting rod, and releasing it automatically retracts it. Tightening the nut completes the fixation. The entire process is smooth and seamless. Compared to existing technologies that require maintaining tension on the pull ring until it is fully inserted, which necessitates continuous force application during operation, this application features a simpler structure, easier operation, stronger vibration resistance, more reliable fixation, lower requirements for mounting hole dimensional accuracy, and a wider range of applicability, better meeting the practical needs of new energy battery monitoring equipment.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-4 This utility model provides a technical solution: a monitoring and early warning device for new energy batteries, including a battery pack 1, a temperature monitor 2, and a fastening assembly consisting of a plug rod 3 and a nut 4. The battery pack 1 serves as the main body of the device and integrates multiple battery cells inside. Its inner wall has pre-drilled mounting holes that match the fastening assembly to ensure the stable fixation of the monitoring components. The temperature monitor 2 uses a high-precision thermocouple or infrared sensor to collect the internal temperature data of the battery pack 1 in real time and transmit it to the terminal via a wireless module. When the temperature exceeds the threshold, an audible and visual early warning is triggered. The side wall of the insertion rod 3 is rotatably mounted with several limiting rods 5 via a pivot. A push rod 6 is slidably mounted at the center of the insertion rod 3 via an elastic member. The limiting rods 5 and push rod 6 are connected so that the pushing rod 6 drives the limiting rods 5 to rotate around the pivot when it slides. A cavity is provided at the center of the insertion rod 3. A lever 10 is fixedly mounted on the side wall of the pivot. The end of the lever 10 is arc-shaped, forming an angle between the lever 10 and the limiting rods 5. A pair of baffles 9 are fixedly sleeved on the push rod 6 at the cavity position, forming a groove between the baffles 9 to accommodate the lever 10. The insertion rod 3 has several limiting rods 5 on the periphery of the cavity. The groove of the position rod 5 has a through hole on the bottom wall for the lever 10 to pass through. One side of the cavity has an insertion hole. The elastic component is a spring 8 embedded in the insertion hole. The end of the push rod 6 extends into the insertion hole and contacts the spring 8. The rod body of the push rod 6 is fixedly sleeved with a limiting sleeve 11. When the spring 8 is in a relaxed state, the limiting sleeve 11 abuts against the insertion rod 3. One end of the push rod 6 passes through the end face of the insertion rod 3 and is fixedly installed with an anti-dislodgement cap. One end of the insertion rod 3 is rotatably installed with a pull ring 7. The outer wall of the insertion rod 3 is threaded with a nut 4. The temperature monitor 2 is locked to the inner wall of the battery pack 1 by the cooperation of the nut 4 and the limiting rod 5.

[0017] During assembly, pressing the push rod 6 causes the limiting rod 5 to rotate around the axis and retract into the groove of the insertion rod 3. Holding the pull ring 7, the insertion rod 3 is inserted into the pre-drilled mounting holes on the temperature monitor 2 and battery pack 1. Once the limiting rod 5 passes through the mounting hole, the push rod 6 is released, the spring 8 releases its elastic potential energy, and the push rod 6 returns to its original position, causing the limiting rod 5 to rotate and expand until it contacts the battery pack 1. Then, the nut 4 is rotated to move along the thread of the insertion rod 3 and contact the temperature monitor 2, completing the installation. The entire process requires no complex tools, effectively improving assembly efficiency compared to traditional bolt fixing methods.

[0018] This application utilizes a linkage design between the push rod 6 and the limiting rod 5. Simply pressing the push rod 6 retracts the limiting rod 5, and releasing it automatically resets and unfolds it. Tightening the nut 4 completes the fixation. The entire process is smooth and seamless. Compared to existing technologies that require maintaining tension on the pull ring until it is inserted into place, which necessitates continuous force application during operation, this application features a simpler structure, easier operation, stronger vibration resistance, more reliable fixation, lower requirements for mounting hole dimensional accuracy, and a wider range of applicability, thus better meeting the practical needs of new energy battery monitoring equipment.
