[0025] With the enhancement of environmental awareness and the transformation of the energy structure, new energy engineering vehicles are gradually replacing traditional diesel engineering vehicles and becoming a new trend in the industry development. In this context, as the core component of new energy engineering vehicles, the performance, reliability and usability of the battery module have a crucial impact on the overall performance and usage efficiency of the vehicle.

[0026] Development history of the battery module of engineering vehicles: As an important tool for infrastructure construction, the power source of engineering vehicles has experienced a transformation from diesel to new energy. Traditional diesel engineering vehicles have won wide applications with their powerful power and reliability, but the resulting environmental pollution and energy waste problems have emerged. To solve these problems, new energy engineering vehicles have emerged, and the battery-driven method has become the mainstream. In the early days, the battery modules of engineering vehicles were mostly simple lead-acid batteries, which had limited capacity and cumbersome replacement and charging processes. With the continuous development of battery technology, new types of batteries such as lithium-ion batteries have gradually been applied to engineering vehicles, and their high energy density, long life and environmental protection characteristics have brought new opportunities for the development of engineering vehicles. However, with the increase in the number of batteries, the weight and volume of the battery module have also increased accordingly, posing challenges to battery replacement and vehicle maintenance. Therefore, developing an efficient and convenient battery module has become an urgent problem to be solved in the industry.

[0027] Structural features of battery assembly: Battery assembly includes key components such as battery body, hanging part, limit part, lifting support mechanism and rolling mechanism. The structural features of each part are as follows: The battery body is the core part of the battery assembly, which is responsible for storing and providing electrical energy. In engineering vehicles, the battery body usually adopts high-performance batteries such as lithium-ion batteries to meet the high power requirements of the vehicle. The design of the battery body needs to consider factors such as capacity, energy density, safety and reliability to ensure that it can operate stably in harsh working environments. The hanging part is set at one end of the battery body and is used to hang with an external lifting and pulling mechanism when replacing the battery. Through the hanging part, the battery body can be easily pushed or pulled to achieve rapid replacement of the battery. The design of the hanging part needs to consider factors such as connection strength, ease of use and safety to ensure that no unexpected situations occur during battery replacement. The limit part is set at the other end of the battery body and is used to position the battery body in the battery installation part of the engineering vehicle. A limit mechanism that cooperates with the limit part can be set in the battery installation part of the engineering vehicle to ensure the stability of the battery body during vehicle operation. The design of the limiter needs to consider factors such as positioning accuracy, wear resistance and impact resistance to prevent the battery body from being damaged by the movement of the battery body in the battery installation part due to external factors such as road conditions. The lifting support mechanism is an important component of the battery assembly and is used to realize the lifting function of the battery body. In engineering vehicles, the lifting support mechanism usually adopts structures such as hydraulic cylinders, connecting rods, and main beams. The movement of the connecting rods and main beams is driven by the extension and contraction of the hydraulic cylinder to realize the lifting and lowering of the battery body. The design of the lifting support mechanism needs to consider factors such as load-bearing capacity, lifting speed and stability to ensure that the lifting and lowering operation of the battery body can be completed smoothly and quickly during the battery replacement process. The rolling mechanism is set at the bottom of the battery body to support the battery body and enable it to move in the horizontal direction when replacing the battery. The rolling mechanism is usually composed of a universal wheel group consisting of one or more universal wheels, and other mechanical rolling structures can also be used. The design of the rolling mechanism needs to consider factors such as load-bearing capacity, rolling resistance and wear resistance to ensure that the battery body can be easily and quickly moved during the battery replacement process.

[0028] Working principle of battery assembly: The working principle is mainly based on the synergy of the hanging part, the limiting part, the lifting support mechanism and the rolling mechanism. When replacing the battery, first lower the battery body to an appropriate height through the lifting support mechanism so that the rolling mechanism contacts the ground and supports the battery body. Then, the hanging part is connected to the external lifting and pulling mechanism, and the push-pull mechanism is used to push or pull the battery body to move in the horizontal direction. During the movement, the limiting part cooperates with the limiting mechanism in the battery installation part of the engineering vehicle to ensure the stability of the battery body in the vehicle. When the battery body moves to the new position, the lifting support mechanism is used to lift the battery body to an appropriate height so that the limiting part and the limiting mechanism cooperate closely to complete the replacement and fixation of the battery.

[0029] Application scenarios of the battery module: It is applicable to various new energy engineering vehicles, such as excavators, loaders, rollers, etc. During the use of engineering vehicles, the battery module needs to be replaced frequently to ensure the continuous operation of the vehicle. The traditional battery replacement method usually adopts hoisting operation, but hoisting operation has safety hazards and requires high requirements for operators. After adopting this battery module, the battery can be replaced by rolling, which not only improves the replacement efficiency but also reduces the safety risk. Advantages of the battery module: After adopting this battery module, the battery can be replaced by rolling, avoiding the tediousness and time-consuming of traditional hoisting operation. At the same time, the design of the hanging part and the limiting part also makes the battery replacement process more convenient and stable, thus greatly improving the replacement efficiency. The traditional battery replacement method adopts hoisting operation, which has safety hazards. After adopting this battery module, the battery replacement process is more stable and safe, reducing the safety risk. In addition, the design of the rolling mechanism also makes the battery more stable during movement, avoiding accidents caused by shaking or tilting. It has stronger flexibility and can adapt to new energy engineering vehicles of different models and specifications. At the same time, the design of the lifting support mechanism and the rolling mechanism also enables the battery module to flexibly adjust the height and position during replacement, thus meeting the usage requirements in different scenarios. Engineering vehicles can make more efficient use of battery resources. Since the battery replacement process is more convenient and fast, the vehicle can return to the working state faster, thus improving the usage efficiency. In addition, this battery module also has good durability and reliability, which can extend the service life of the battery and reduce the maintenance cost.

[0030] Analysis of the innovation points of the battery module: Innovative components such as the hanging part, the limiting part, the lifting support mechanism and the rolling mechanism are adopted in the structural design to achieve the rapid replacement and stable fixation of the battery module. The design of these innovative components not only improves the efficiency and safety of battery replacement but also enhances the flexibility and durability of the battery module. The working principle is based on the coordinated action of the hanging part, the limiting part, the lifting support mechanism and the rolling mechanism to achieve the rapid movement and stable fixation of the battery module in the horizontal direction. This innovation in the working principle makes the battery replacement process more convenient and efficient, reducing the operation difficulty and safety risk. It is applicable to various new energy engineering vehicles and can adapt to the usage requirements in different scenarios. This innovation in the application scenario makes this battery module have a broader application prospect and market demand.

[0031] Technical challenges, load-bearing capacity: The battery module needs to bear the weight of the battery main body and the impact force that may occur during use, so it has high requirements for its load-bearing capacity. Stability: During the battery replacement process, the battery module needs to remain stable to avoid accidents caused by shaking or tilting. Durability: The battery module needs to withstand long-term use and wear, so it needs to have good durability and reliability.

[0032] Solutions, optimize the structural design: By optimizing the structural design of the battery module, such as increasing the thickness and strength of the load-bearing components, using high-strength materials, etc., improve the load-bearing capacity of the battery module. Strengthen the stability control: Strengthen the stability control in the design of the battery module, such as increasing the number and strength of the limiting components, optimizing the design of the rolling mechanism, etc., to ensure the stability of the battery module during the replacement process. Improve the durability: Adopt high-quality materials and advanced manufacturing processes to improve the durability and reliability of the battery module. At the same time, regularly inspect and maintain the battery module to detect and handle potential problems in a timely manner.

[0033] With the continuous development of Internet of Things and artificial intelligence technologies, future battery modules will develop towards the intelligent direction. By integrating intelligent components such as sensors and controllers, functions such as remote monitoring, fault warning, and automatic maintenance of the battery module are realized, improving the reliability and usage efficiency of the battery module. Lightweight is one of the important trends in the development of new energy engineering vehicles. Future battery modules will adopt lighter materials and more optimized structural designs to reduce the weight and volume of the battery module and improve the fuel economy and endurance of the vehicle. In order to promote the popularization and development of new energy engineering vehicles, future battery modules will develop towards the standardization direction. By formulating unified battery module standards and specifications, battery interchange and sharing between different brands and models of new energy engineering vehicles are realized, reducing the maintenance cost and usage difficulty of users. Environmental protection is one of the important directions in the development of future engineering vehicles. Future battery modules will adopt more environmentally friendly materials and manufacturing processes to reduce the impact on the environment. At the same time, by optimizing the recycling and reuse mechanism of the battery module, the circular utilization of resources and sustainable development are realized.

[0034] Maintenance and Care of Battery Components: To ensure the long-term stable operation of battery components in engineering vehicles, it is crucial to perform regular maintenance and care on them. The following are some key maintenance and care measures: Regularly detect parameters such as the voltage, current, and internal resistance of the battery body to ensure it is in a normal state. Once any abnormality is found, immediate investigation and handling should be carried out to prevent the expansion of the fault. Regularly clean the dust and dirt on the surface of the battery components to prevent it from affecting the heat dissipation and performance of the battery components. At the same time, avoid using corrosive cleaning agents to prevent damage to the battery components. Regularly check the wear conditions of the hanging part and the limiting part to ensure its firm connection and accurate positioning. Once severe wear or looseness is found, immediate replacement or tightening should be carried out. Regularly lubricate the bearings and rollers of the rolling mechanism to reduce friction and wear and improve the flexibility and durability of the rolling mechanism. Regularly check the wear and deformation conditions of components such as the hydraulic cylinder, connecting rod, and main beam of the lifting support mechanism to ensure its load-bearing capacity and stability. Once any abnormality is found, immediate repair or replacement should be carried out. When using battery components, avoid over-discharging and over-charging to extend the service life of the battery. At the same time, follow the charging recommendations of the battery manufacturer and use a suitable charger for charging. When storing battery components, choose a dry, well-ventilated, and cool environment, and avoid direct sunlight and high temperatures. At the same time, avoid placing the battery components together with flammable and explosive items to prevent safety accidents such as fires and explosions. Establish a detailed maintenance file for the battery components, recording information such as the time, content, and replaced parts of each maintenance. This helps to track the maintenance history of the battery components, promptly discover potential problems, and take corresponding measures.

[0035] With the increasing awareness of environmental protection, the issues of environmental protection and sustainable development of battery components have also received increasing attention. In the design and manufacturing process of battery components, environmentally friendly materials such as recyclable materials and non-toxic materials should be preferentially used. This helps to reduce environmental pollution during the production and use of battery components. Establish a perfect battery recycling mechanism to recycle and reuse waste batteries. By recycling useful materials from waste batteries, resource waste can be reduced and environmental pollution can be lowered. By optimizing the design and manufacturing process of battery components, improve energy utilization efficiency. This can not only extend the service life of the battery but also reduce energy consumption and emissions, which is of positive significance to environmental protection. Continuously promote the innovation and development of battery technology to improve the energy density, safety, and reliability of the battery. Through technological innovation, the cost of battery components can be reduced and the performance can be improved, thus promoting the popularization and development of new energy engineering vehicles. The government should strengthen policy guidance and support for new energy engineering vehicles and battery components. By formulating relevant regulations and standards, promote the environmental protection and sustainable development of new energy engineering vehicles and battery components. At the same time, provide incentive measures such as financial subsidies and tax incentives to encourage enterprises to increase R & D investment and promote technological innovation.

[0036] With the continuous development of new energy technologies and the expansion of the market, new energy engineering vehicles will gradually replace traditional diesel engineering vehicles and become the new mainstream of the industry's development. At the same time, as one of the core components of new energy engineering vehicles, battery components will also embrace a broader development prospect and opportunities. Therefore, we need to continuously pay attention to the technological innovation and development trends of battery components, strengthen the emphasis on their maintenance and upkeep, and promote their environmental protection and sustainable development. It is believed that in the near future, new energy engineering vehicles and battery components will bring more convenient, efficient, and environmentally friendly solutions to our lives and production. By optimizing the structural design, strengthening stability control, and improving durability and other measures, the technical challenges of battery components in terms of load-bearing capacity, stability, and durability have been solved. In the future, driven by development trends such as intelligentization, lightweight, standardization, and environmental protection, it will have a broader application prospect and market demand. However, the development of new energy engineering vehicles still faces many challenges, such as the bottleneck of battery technology, the shortage of charging facilities, etc. Therefore, it is necessary to continuously increase R & D investment, promote technological innovation and industrial upgrading to meet market demand and drive the rapid development of new energy engineering vehicles.
