Description

Technical Field

[0001] This utility model relates to the field of energy storage box technology, specifically to an energy storage equipment box assembly for new energy sources. Background Technology

[0002] Against the backdrop of the rapid development of the new energy storage industry, energy storage equipment boxes, as the carriers and protectors of core components such as energy storage batteries and electronic control modules, directly determine the safety and stability of the energy storage system.

[0003] Current mainstream energy storage equipment enclosure designs are mostly at a basic level, relying on a single outer shell material for structural strength and lacking internal reinforcing structures. When subjected to external impacts, such as transportation bumps, accidental collisions, or heavy object impacts, the enclosure is prone to deformation or even breakage, directly damaging the internal energy storage components and causing safety hazards such as short circuits and leakage. The protection mechanisms for abnormal operating conditions inside the enclosure are inadequate. If the internal pressure of the energy storage components suddenly increases due to overload, short circuit, or thermal runaway during operation, most existing enclosures are not equipped with efficient pressure relief devices or only use simple vent designs, which cannot quickly and stably release high pressure, making it easy to cause serious safety accidents such as enclosure explosion and component fire. At the same time, although some enclosures have attempted to add buffer structures, they are mostly single spring buffer designs, which are difficult to effectively weaken instantaneous impact forces and have limited buffering effects, still unable to fully resist the threats posed by internal and external risks to the equipment. In view of this, a new type of energy storage equipment enclosure for new energy is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an energy storage equipment box for new energy sources, which solves the problem of poor protection of energy storage equipment boxes.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an energy storage equipment box assembly for new energy sources, comprising an energy storage box body, wherein a box door is hinged to the front surface of the energy storage box body; The energy storage box is equipped with a protective mechanism, which includes a pressure relief valve, an air inlet grille, a reinforcing frame, a fixed roller, a spring, and a sliding block. The pressure relief valve is fixedly installed on the front surface of the energy storage tank, and the air inlet grille is fixedly installed on the front surface of the energy storage tank. Multiple reinforcing frames are fixedly installed in the inner wall of the energy storage box.

[0006] Preferably, the plurality of fixed rollers are fixedly installed in the inner wall of the energy storage box, and the plurality of sliding blocks are respectively slidably sleeved on the outer surface of the plurality of fixed rollers; The opposite ends of multiple springs are respectively fixedly installed on the opposite sides of multiple sliding blocks, and the opposite ends of multiple springs are respectively fixedly installed on the opposite sides of multiple fixed roller connecting plates.

[0013] Compared with the prior art, this utility model provides an energy storage equipment box group for new energy sources, which has the following beneficial effects: This energy storage equipment unit for new energy uses a reinforced frame to enhance the overall strength of the unit and resist external impacts and deformations. The explosion-proof buffer plate directly absorbs the impact, and the force is transmitted to the hydraulic damper and spring through the piston rod. This forms a multi-stage buffering system with initial spring buffering, hydraulic damping for slow release, and secondary spring absorption, which significantly reduces the impact force.

[0017] 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.

[0018] Please see Figure 1-7 This utility model provides a new technical solution: an energy storage equipment box for new energy, including an energy storage box 1: as the core load-bearing structure, it provides installation space and basic support for the internal energy storage components and protective mechanisms, ensures the structural integrity of the overall equipment box, and is the outer protective frame of the energy storage equipment.

[0019] Door 2: Hinged to the front surface of the energy storage box 1, it enables the opening and closing of the box, facilitating the installation, inspection and maintenance of internal equipment, while also assisting in sealing the box and reducing interference from the external environment.

[0020] Pressure relief valve 3: Fixed on the front surface of energy storage tank 1. When the pressure inside the tank rises abnormally due to faults or other reasons, it will automatically open to relieve pressure, so as to avoid excessive pressure from damaging the tank or causing safety accidents, and to ensure the safe operation of the equipment.

[0021] Air intake grille 4: Installed on the front surface of the energy storage box 1, it is used to introduce external cold air and filter dust and impurities in the air, providing a clean air intake channel for the ventilation and heat dissipation system inside the box and maintaining heat dissipation efficiency.

[0022] Reinforced frame 5: Fixed to the inner wall of the energy storage box 1, it enhances the overall structural strength and deformation resistance of the box, prevents deformation of the box due to external impact or the weight of internal components, and improves the durability of the equipment.

[0023] Fixed roller 6: Installed on the inner wall of the energy storage box 1, it provides sliding guidance for the sliding block 8, restricts its movement trajectory, ensures that the sliding block 8 moves stably under the action of the spring 7, and ensures the normal operation of the buffer mechanism.

[0024] Spring 7: Both ends are connected to the sliding block 8 and the fixed roller 6 respectively. When the explosion-proof buffer plate 12 is impacted, it absorbs part of the impact force through its own expansion and contraction deformation, playing a preliminary buffering and shock absorption role and protecting the internal components.

[0025] Sliding block 8: Sliding sleeve on the outer surface of fixed roller 6, connecting spring 7 and hydraulic damper 9, transmitting buffering force to each component, and sliding synchronously with the impact, coordinating the buffering action of spring 7 and hydraulic damper 9.

[0026] Hydraulic damper 9: Rotatably connected to the lower surface of sliding block 8, working in conjunction with spring 7, it slows down the release speed of impact energy through the damping effect of hydraulic oil, avoids excessive instantaneous impact force, and achieves smooth buffering.

[0027] Second spring 10: Fixed on the lower surface of hydraulic damper 9, assisting hydraulic damper 9 in enhancing buffering effect, further absorbing residual impact energy, improving the shock absorption performance of the overall protection mechanism, and providing double protection for internal components. Hydraulic damper 9 and second spring 10 are coaxially arranged.

[0028] Piston rod 11: Fixed to the lower surface of hydraulic damper 9 and slidably sleeved inside it, it transmits the damping force of hydraulic damper 9 to explosion-proof buffer plate 12, and extends and retracts during impact to coordinate the displacement and force transmission of the buffer mechanism.

[0029] Explosion-proof buffer plate 12: Installed at the lower end of piston rod 11, directly contacting possible impact sources, dispersing external impacts or internal abnormal forces to piston rod 11, weakening impact force through multi-stage buffer structure, and protecting core energy storage components.

[0030] Storage plate 13: Both are fixed on the inner surface of the energy storage box 1, serving as an installation platform for core components such as energy storage batteries, enabling the orderly arrangement of components in layers, and providing an installation carrier for the flow guide hopper 15, thus optimizing the utilization of internal space.

[0031] Ventilation holes 14 (rectangular / round / honeycomb): are opened on the upper surface of the shelf 13 to allow cold air to pass through the shelf and circulate inside the box. Different shapes are designed to increase the ventilation area, optimize airflow distribution, and improve heat dissipation uniformity.

[0032] Airflow guide 15: Fixed to the lower surface of the shelf 13, it guides the airflow blown by the fan 16 to flow precisely to the heat-generating components, concentrates the airflow to enhance the heat dissipation effect, and avoids heat dissipation dead zones caused by airflow dispersion.

[0033] Fan 16: Installed on the lower surface of the air guide hopper 15, it serves as an active heat dissipation power source, accelerates the airflow inside the box, and guides the cold air entering through the air intake grille 4 through the air guide hopper 15 and ventilation holes 14 to the heat-generating components, thus carrying away the heat.

[0034] In this energy storage unit for new energy applications, the debris and shockwave from the explosion first impact the explosion-proof buffer plate 12. The buffer plate 12, under pressure, pushes the piston rod 11, which slides rapidly inward along the inner surface of the hydraulic damper 9. The hydraulic oil inside the damper 9 creates a strong damping force, hindering the piston rod 11 from sliding. Simultaneously, the second spring 10 is compressed by the relative movement of the piston rod 11 and the hydraulic damper 9, absorbing some of the impact energy. Once the impact energy is dissipated, the elastic potential energy of the second spring 10 pushes the piston rod 11 out of the hydraulic damper 9, and the explosion-proof buffer plate 12 returns to its original position. When the temperature inside the unit rises, the fan 16 starts, generating an upward airflow. After being guided by the guide bucket 15, the airflow passes vertically upward through the ventilation holes 14 on the shelf 13 and comes into contact with the heating element on the shelf 13 to complete heat exchange. At the same time, external cold air continuously enters the energy storage box 1 through the air inlet grille 4 to supplement the airflow. The hot airflow is accelerated and discharged under the action of the fan 16 until the temperature inside the box drops to a safe range. The fan 16 can be automatically started and stopped according to the temperature control. When the air pressure inside the energy storage box 1 rises to the set threshold, the valve core of the pressure relief valve 3 opens under the action of pressure, and the high-pressure gas is discharged through the exhaust port of the pressure relief valve 3. When the air pressure inside the box drops to the normal range, the valve core of the pressure relief valve 3 closes under the action of its own reset structure and stops exhausting. Example 1: Honeycomb-shaped ventilation holes for bump resistance and quiet operation of vehicle-mounted mobile energy storage devices. like Figure 7 As shown: A mobile energy storage device for emergency rescue vehicles uses the energy storage device box group of this utility model as the core energy storage unit. It is installed in the cargo compartment of a medium-sized truck for temporary power supply at disaster sites such as earthquakes and floods. In this scenario, the device needs to withstand the continuous bumps during vehicle travel, while controlling the operating noise to avoid affecting communication at the rescue site. In this scenario, the storage panel 13 uses honeycomb ventilation holes 14. The honeycomb array is arranged in a tight hexagonal pattern with an opening rate of 40%. Its effect is as follows: the hexagonal units of the honeycomb structure have excellent mechanical stability and can disperse the impact force generated by bumps to the entire storage panel. On-site simulation test shows that after the vehicle has been continuously bumping for 2 hours, the storage panel with honeycomb ventilation holes has no obvious deformation, and the loosening rate of the fixing bolts of the battery module is only 2%. In contrast, the storage panel with rectangular ventilation holes has a bolt loosening rate of 8% under the same conditions, requiring additional reinforcement. When the airflow generated by the fan 16 passes through the honeycomb channels, the noise will be attenuated due to the multiple turns and friction of the channels. Test data shows that the noise level of the device during operation is 62dB, which meets the quiet requirements of the rescue site compared to rectangular ventilation holes. At the same time, the multi-channel structure of the honeycomb holes allows airflow to be diffused more evenly into the gaps between the battery modules, avoiding additional noise caused by local airflow turbulence. There may be small particles such as sand and debris at the disaster site. The dense array of honeycomb holes can form a barrier effect. In the simulated debris splash test, the particle blocking rate of the honeycomb ventilation holes reached 90%, effectively protecting the battery module terminals from the risk of short circuit caused by particle impact.

[0035] Example 3: Circular ventilation holes for preventing foreign objects and reducing wind resistance in distributed residential energy storage devices. like Figure 6 As shown: A distributed household energy storage device in a residential community adopts the energy storage device box of this utility model and is installed on the balcony or corner of the courtyard of the residents. In this scenario, the device needs to cope with the intrusion of small foreign objects such as hair, fibers, and insects in daily life. At the same time, due to the limited space on the balcony, it is necessary to control the size of the device and the operating noise. In addition, residents have high requirements for the ease of maintenance of the device. In this scenario, the storage panel 13 uses round ventilation holes 14. The arc-shaped structure and 10mm diameter of the round holes effectively prevent hair, fibers, and insects from entering the device. Long-term operation tests show that the amount of foreign matter accumulated inside is only 1 / 3 of that of rectangular ventilation holes, eliminating the need for frequent disassembly and cleaning, thus reducing maintenance costs for residents. Furthermore, the smooth edges of the round holes prevent fibrous foreign objects from getting caught at the openings, further reducing the risk of blockage. When airflow passes through the round holes, the smooth walls without right-angle turns reduce the drag coefficient compared to rectangular holes, allowing the fan 16 to achieve the required ventilation volume at a lower speed. Tests show that this does not interfere with residents' daily lives. Low-speed operation also extends the fan's lifespan, increasing the mean time between failures (MTBF) compared to the rectangular ventilation hole scenario. The round ventilation holes can be mass-produced using a stamping process, reducing processing costs compared to the precision molding of honeycomb holes. Additionally, the round hole structure has less impact on stress concentration in the storage panel material, allowing for the use of thinner sheets. This reduces the overall weight and manufacturing cost of the device while maintaining structural strength, making it more suitable for the economic needs of residential energy storage.
