Description

Technical Field

[0001] The utility model relates to the technical field of new energy automobile manufacturing, and in particular to a new energy automobile battery pack spontaneous combustion detection device. Background Art

[0002] New energy vehicles have become a widely used means of transportation, and the production efficiency requirements for their manufacturers are gradually increasing. As the core power component of new energy vehicles, the safety performance of batteries is directly related to the safety of the entire vehicle and its passengers. In the event of a car accident, the vehicle chassis is often easily impacted, which may cause the battery cells or high-voltage devices inside the battery pack to be squeezed or punctured, which may cause short circuits, fires, or even explosions. In existing production, the impact test of battery spontaneous combustion detection equipment can simulate the impact that the vehicle may suffer in an actual car accident, thereby evaluating the safety performance of the battery pack under extreme conditions. This test helps to promptly discover potential problems in battery design or manufacturing, and take corresponding measures to improve them, thereby significantly reducing the risk of battery spontaneous combustion under impact.

[0003] At present, the widely used testing equipment for new energy vehicle batteries has a small overall layout and is used to detect battery packs that are not assembled to the chassis. If you want a better simulation effect, the battery will be fully assembled into the car chassis, which will have the following problems: Due to the large chassis of the car, the battery of the entire car chassis cannot be tested at one time, and it is necessary to manually move the position for staged testing. Using existing equipment for testing, due to the need for staged testing, the testers need to move the vehicle or equipment many times, which will greatly increase the testing time and reduce the testing efficiency, thereby affecting the production efficiency of the car. At the same time, frequent movement and positioning operations will also increase the possibility of errors. For example, inaccurate positioning leads to missed inspections or repeated inspections, and staged inspections may cause certain areas to be ignored or not fully inspected during the movement, thereby reducing the accuracy of the inspection. In addition, frequent equipment movement may cause accelerated wear of equipment components and increase the risk of failure. If the operation is improper or the equipment fails, it may cause damage to the equipment or vehicle, and may even cause safety accidents. Utility Model Content

[0017] Figure 2 It is a partially enlarged schematic diagram of a new energy vehicle battery pack spontaneous combustion detection device according to an embodiment of the utility model. DETAILED DESCRIPTION

[0018] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings to further illustrate the present invention.

[0019] First, combine Figure 1 , 2 The new energy vehicle battery pack spontaneous combustion detection device according to the embodiment of the utility model is described, which is widely used in battery pack research and development and testing, automobile repair and maintenance, etc. In this description, the quality inspection of new energy vehicle manufacturers is used as an example.

[0020] like Figure 1 , 2 As shown, the new energy vehicle battery pack spontaneous combustion detection device of the embodiment of the utility model is used to detect the battery pack assembled on the chassis of the new energy vehicle, and has a frame 1, a drop tower 2 and a three-axis movable track mechanism 3.

[0021] Specifically, Figure 1 , 2 As shown, the chassis of the automobile enters the frame 1 under external force and is relatively fixed to the frame 1. As the main structure of the entire detection equipment, it provides a stable basic support, can carry and fix the chassis of the automobile, and support the drop tower 2 and the three-axis movable track mechanism 3, to ensure stability and safety during the detection process; the drop tower 2 includes an impact detection head, which can move along the extension direction of the drop tower 2 and impact the battery pack to be detected. The design of the impact detection head can accurately control the impact force and angle, simulate the collision or fall that the automobile may encounter during actual driving, and perform impact detection on the battery pack; the three-axis movable track mechanism 3 is arranged on the frame 1, and the three-axis movable track mechanism 3 includes three mutually perpendicular axial tracks. The drop tower 2 can move along the three axial tracks. The design of the three-axis movable track mechanism 3 makes the detection process more flexible and comprehensive, which can ensure that all key parts of the battery pack are detected and reduce the possibility of missed detection.

[0022] Preferably, the automobile chassis is fixed to the frame 1 by a locking member (not shown in the figure). By fixing the automobile chassis to the frame 1 by a special locking member, the stability of the chassis during the detection process can be ensured and detection errors caused by vibration or movement can be prevented.

[0023] Preferably, the locking member is a vacuum suction cup. The vacuum suction cup can be used as the locking member to fix the chassis by adsorbing the surface of the chassis. This fixing method will not cause mechanical damage to the chassis.

[0024] Preferably, the locking member is an electromagnetic clamp, which uses electromagnetic force to clamp the chassis, has the advantages of large clamping force, fast response speed, and easy operation, and is suitable for chassis of different shapes and sizes.

[0025] Preferably, the rack 1 includes a frame coupled to the automobile chassis, and the automobile chassis is snapped into the frame and fixed. This design enables the chassis to be more accurately positioned on the rack 1, thereby improving the accuracy of the detection. At the same time, by snapping the chassis into the frame to fix the chassis, the stability of the chassis during the detection process can be ensured.

[0026] Preferably, the three axial tracks of the three-axis moving track mechanism 3 are all ball screw assemblies 31. The ball screw assembly 31 has the characteristics of high precision, high rigidity and long life, which can ensure the stability and accuracy of the drop tower 2 during movement, thereby improving the accuracy and reliability of detection.

[0027] Preferably, the axial track along the axial direction of the automobile chassis among the three axial tracks of the three-axis moving track mechanism 3 is a synchronous belt transmission assembly 32. The chassis in the axial direction is longer, and the ball screw will have a certain instability. At least one of the other two axial tracks is a ball screw assembly 31. This design combines the high speed and stability of the synchronous belt transmission assembly and the high precision of the ball screw assembly 31, so that the drop tower 2 has a faster speed when moving along the axial direction of the chassis, while maintaining high precision when moving in other directions. This helps to improve detection efficiency while ensuring the stability and accuracy of detection.

[0028] Preferably, at least one limit assembly 33 is provided on the frame 1 adjacent to the synchronous belt transmission assembly 32, and the limit assembly 33 includes a tensioning wheel 331, which can ensure the tension of the synchronous belt transmission assembly and prevent transmission errors caused by looseness. This helps to improve the accuracy and reliability of detection.

[0029] Preferably, the limiting assembly 33 further includes a pair of ribs 332, which are respectively arranged on both sides of the tensioning wheel 331. The ribs 332 can limit the movement range of the synchronous belt to prevent the synchronous belt from deviating from the track or shifting during movement. This helps to further improve the stability and accuracy of the detection.

[0030] Preferably, a pair of ribs 332 are provided with photoelectric sensors, which can monitor the position of the ribs 332 in real time, thereby determining whether the synchronous belt is in a normal motion state. If the synchronous belt deviates or deviates from the track, the photoelectric sensor can immediately send a signal to stop the detection process to avoid damage to the chassis or affect the detection results.

[0031] When in use, the chassis of the car is pushed into the rack 1 and secured to the rack 1 by appropriate fixing means. The impact detection head in the drop tower 2 moves along the extension direction of the drop tower 2 to perform impact detection on the battery pack to simulate the collision situation in the real environment. At the same time, the three-axis mobile track mechanism 3 allows the drop tower 2 to move on three mutually perpendicular axial tracks to ensure comprehensive and accurate detection of the battery pack. The entire detection process can reduce manual intervention, improve detection speed and accuracy, thereby ensuring the stability and reliability of the battery in the car chassis under various conditions.

[0032] Above, refer to Figure 1 , 2 The invention describes a new energy vehicle battery pack self-ignition detection device according to an embodiment of the utility model, which can directly detect the battery pack that has been assembled into the vehicle chassis, and the detection effect is closer to the real situation. At the same time, compared with the staged mobile detection, the battery detection of the entire new energy vehicle chassis is integrated and continuous. The whole machine push-in design reduces the time of manual disassembly and assembly, making the detection process more efficient. The detection process can reduce human intervention and improve the detection speed and accuracy; at the same time, the centralized detection system can ensure that all key parts are fully detected, reducing the possibility of missed detection; the impact force and angle can be more accurately controlled to avoid accidents. Through comprehensive impact detection, the stability and reliability of the vehicle chassis under various conditions can be ensured. The overall detection simulates the real situation more accurately, can timely discover and solve potential problems, and ensure the stability and reliability of the battery of the vehicle chassis under various conditions.
