Description

Technical Field

[0001] This application relates to the field of energy storage battery pack testing and transportation technology, and in particular to an energy storage battery pack protection device. Background Technology

[0002] An energy storage battery pack is a complete energy storage unit composed of multiple battery cells connected in series and parallel, and equipped with a corresponding battery management system (BMS), structural components, electrical connectors, etc. It can flexibly design parameters such as voltage, capacity and power of the battery pack according to different application scenarios and needs to realize the storage and release of electrical energy.

[0003] In the research, development, production and application of energy storage battery packs, it is crucial to conduct accurate reliability testing. Such testing requires sending the battery packs to professional testing laboratories or testing institutions.

[0004] For example, when battery packs are being charged and discharged, they need to be transported from the local area to the testing equipment (such as a large temperature chamber). During the transportation and testing of battery packs, some problems are encountered. On the one hand, the battery packs lack effective fixing and protection measures during transportation, and are easily damaged by shaking, vibration and external impact, which affects the battery performance and lifespan, thereby reducing the reliability of the entire energy storage system. On the other hand, it is difficult to fix batteries of different sizes, making it difficult to achieve universality.

[0005] In view of the above, this application is hereby submitted. Utility Model Content

[0010] Multiple limiting seats are provided, each of which is disposed on the tray and forms a battery pack accommodating space. Each limiting seat includes a fixed part, a movable part, an operating part, and an elastic damping component. The fixed part is fixed to the tray, the movable part is movably disposed on the tray, the elastic damping component is connected to the movable part and is used to contact the battery pack, and the operating component is disposed on the fixed part and is in a transmission cooperation with the movable part to drive the movable part to move closer to or away from the battery pack located in the battery pack accommodating space, and to squeeze or release the elastic damping component.

[0011] Optionally, the fixing part has a threaded through groove;

[0012] The operating part has a screw, which is disposed through the threaded groove;

[0016] Optionally, a guide hole is provided on the fixing part;

[0017] A guide rod is provided on the movable part, and the guide rod is slidably disposed in the guide hole;

[0018] The screw is rotatably connected to the movable part;

[0019] The tray restricts the rotation of the movable part, and the rotation of the operating part can cause the movable part to translate along the extension direction of the operating part.

[0020] Optionally, a knob is provided at the end of the screw that is away from the movable part;

[0021] The outer diameter of the knob is larger than the outer diameter of the screw.

[0022] Optionally, the elastic damping component includes a positioning plate and an elastic assembly;

[0023] The positioning plate has a flat, fitting surface for fitting the surface of the battery pack;

[0024] The elastic component is disposed between the positioning plate and the movable part;

[0025] As the actuator drives the movable part closer to the battery pack, the deformation of the elastic component increases.

[0026] Optionally, the elastic component includes a plurality of dampers;

Detailed Implementation

[0045] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0047] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0048] like Figure 1 and Figure 2As shown, this application provides an energy storage battery pack protection device, including a tray 1 and multiple limiting seats 2. The tray 1 has a transfer mating part 3, and each of the limiting seats 2 is disposed on the tray 1, forming a battery pack accommodating space. Each limiting seat 2 includes a fixing part 21, a movable part 22, an operating part, and an elastic damping component. The fixing part 21 is fixed to the tray 1, the movable part 22 is movably disposed on the tray 1, and the elastic damping component is connected to the movable part 22. The elastic damping component is used to contact the battery pack 4. The operating component is disposed on the fixing part 21, and the operating part is in a transmission fit with the movable part 22 to drive the movable part 22 to move closer to or away from the battery pack 4 located in the battery pack accommodating space, squeezing or releasing the elastic damping component. The energy storage battery pack protection device provided in this application achieves precise fixing and effective vibration damping of the battery pack 4 through the synergistic action of the fixing part 21, the movable part 22, the operating part, and the elastic damping component. During transportation and installation on testing instruments, even if bumps or vibrations occur, the elastic damping components can quickly absorb and disperse energy, ensuring that the impact on battery pack 4 is minimized, thereby greatly improving the safety and stability of battery pack 4.

[0049] Secondly, by adjusting the operating part, the position of the movable part 22 can be changed, thereby adjusting the clamping force and adapting to battery packs 4 of different specifications and sizes. This design not only simplifies the operation process but also reduces the cost of replacing protection devices due to different battery pack 4 specifications, providing strong support for the widespread application of energy storage battery packs 4.

[0050] Furthermore, the transfer fitting part 3 on pallet 1 is designed with actual transportation needs in mind, enabling it to interface with transport vehicles and equipment, ensuring the smooth and safe transfer of battery pack 4. This user-friendly design not only improves work efficiency but also reduces the risk of damage to battery pack 4 due to improper transfer.

[0051] In summary, the energy storage battery pack protection device provided in this application, with its multiple protection mechanisms and universally designed transfer and assembly part 3, provides strong protection for the safe transportation and reliable testing of the energy storage battery pack 4.

[0052] In some possible implementations, the fixing part 21 has a threaded groove, and the operating part has a screw 27 that passes through the threaded groove. The end of the screw 27 is connected to the movable part 22. The end of the movable part 22 facing away from the screw 27 is connected to the elastic damping component. Under the action of external force, the operating part can rotate and move along the threaded groove to move the movable part 22 closer to or away from the battery pack 4. In this structure, the operator can precisely control the movement distance of the movable part 22 simply by rotating the operating part, and easily achieve fine adjustment of the clamping force on the battery pack 4. This threaded drive method has self-locking properties; once the operating part stops rotating, the movable part 22 will stabilize in its current position and will not move on its own due to vibration or external force, ensuring the reliability of the battery pack 4 fixation.

[0053] The operator can also adjust the position of the movable part 22 by rotating the operating part according to the specific specifications and dimensions of the battery pack 4, thereby changing the clamping force of the elastic damping component on the battery pack 4. This adjustable design allows the protective device to adapt to battery packs 4 of different specifications and sizes, greatly improving its versatility and practicality.

[0054] In some possible implementations, the fixed part 21 is provided with a guide hole, and the movable part 22 is provided with a guide rod 26, which is slidably disposed in the guide hole. The screw 27 is rotatably connected to the movable part 22, the tray 1 restricts the rotation of the movable part 22, and the rotation of the operating part can drive the movable part 22 to translate along the extension direction of the operating part.

[0055] The design of the guide hole and guide rod 26 provides precise guidance for the movement of the movable part 22, preventing it from shifting or wobbling during movement, thus ensuring the accuracy of the battery pack 4's fixation. At the same time, this structure also enhances the stability of the entire protection device, ensuring that the battery pack 4 maintains a stable position during transportation or testing.

[0056] Furthermore, the connection between one end of the screw 27 and the movable part 22 is rotatable but not slidable along the axial direction of the screw 27. The connection method can be various, such as setting a bearing between the screw 27 and the movable part 22, welding the screw 27 to the inner ring of the bearing, and welding the movable part 22 to the outer ring of the bearing.

[0057] In some possible implementations, a knob portion 28 is provided at the end of the screw 27 opposite to the movable part 22, and the outer diameter of the knob portion 28 is larger than the outer diameter of the screw 27. The knob portion 28 can be flower-shaped, polygonal, or the like.

[0058] The knob 28 is designed to allow operators to manually rotate the control unit, or use tools to rotate the screw 27, improving ease of operation and efficiency. The larger outer diameter design makes it easier for operators to apply force during rotation, reducing operational difficulty.

[0059] In some possible implementations, the elastic damping component includes a positioning plate 23 and an elastic assembly. The positioning plate 23 has a flat contact surface for contacting the surface of the battery pack 4. The elastic assembly is disposed between the positioning plate 23 and the movable part 22. As the operating element drives the movable part 22 closer to the battery pack 4, the deformation of the elastic assembly increases. The flat contact surface design of the positioning plate 23 ensures sufficient contact with the surface of the battery pack 4, thereby effectively transmitting the damping force. The elastic assembly deforms when the movable part 22 approaches the battery pack 4, absorbing and dispersing the vibration energy generated during transportation or testing, further protecting the battery pack 4 from impact damage. This structure not only improves the damping effect but also extends the service life of the battery pack 4.

[0060] In some possible implementations, the elastic component includes multiple dampers 25, which are spaced apart and arranged in parallel. The two ends of each damper 25 are connected to the positioning plate 23 and the movable part 22, respectively. The dampers 25 effectively attenuate vibration energy by converting mechanical energy into heat energy through their internal damping medium, thereby reducing vibration transmitted to the battery pack 4. Using multiple dampers 25 in parallel can distribute the force, improving the reliability and durability of the entire elastic vibration damping system.

[0061] In some possible implementations, the elastic component further includes multiple springs 24, which are sleeved on the damper 25, with their ends abutting against the positioning plate 23 and the movable part 22, respectively. The springs 24 not only provide additional elastic restoring force, ensuring the movable part 22 quickly returns to its initial position after release, but also work in conjunction with the damper 25 to form a spring-damper two-stage vibration reduction system. This combined design further enhances the vibration reduction performance of the protection device, enabling it to cope with more complex vibration environments. Furthermore, the springs 24 also provide protection for the damper 25.

[0062] The transfer fitting part 3 can take various forms to better meet the docking needs of different transport vehicles and equipment. For example, when the battery pack 4 is transferred by hoisting, the transfer fitting part 3 can be designed as lifting rings located at the four corners of the pallet 1. These lifting rings have sufficient strength and load-bearing capacity to reliably connect with the hooks of the hoisting equipment, ensuring that the battery pack 4 will not slip or tilt during the hoisting process, thus guaranteeing the safety and stability of the hoisting operation.

[0063] If forklifts are required for handling during transportation, the transfer assembly 3 can be designed as multiple support columns 5 mounted on the pallet 1 and insert slots formed between the support columns 5. The support columns 5 are evenly distributed at the bottom of the pallet 1, providing stable support for the pallet 1. Simultaneously, the size and shape of the insert slots match the forklift's forks, allowing the forklift to easily insert its forks into the slots for rapid handling of the pallet 1. This design not only improves handling efficiency but also reduces the risk of damage to the battery pack 4 due to improper handling.

[0064] In some possible implementations, a row of first limiting seats 2 is provided on both sides of the tray 1 along a first direction, and the first limiting seats 2 in each row are arranged at intervals along a second direction. At least one second limiting seat 2 is provided on both sides of the tray 1 along the second direction, with one second limiting seat 2 on one side positioned close to the first limiting seat 2 on the same side to avoid obstructing the terminal block on the battery pack 4, and the second limiting seat 2 on the other side positioned centrally. This layout design fully considers the actual structure and transportation requirements of the battery pack 4. By rationally setting the position and number of the limiting seats 2, the stability and safety of the battery pack 4 during transportation are ensured. Simultaneously, the design to avoid obstructing the terminal block also prevents damage to the terminal block during fixing, improving the practicality and reliability of the entire protection device.

[0065] The above description is merely a preferred embodiment of this application and is not intended to limit this application in any way. Although this application has disclosed the preferred embodiment as above, it is not intended to limit this application. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the technical solution of this application. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this application without departing from the scope of the technical solution of this application shall still fall within the scope of this application.
