Description

Technical Field

[0001] The utility model relates to a lithium battery pack, and more specifically, to a lithium battery pack with a protection structure. Background Art

[0002] A new energy lithium battery pack refers to a battery pack that uses lithium-ion batteries as energy storage devices. It is an important component for driving new energy vehicles (such as electric vehicles, hybrid vehicles, etc.). When the lithium battery pack is in use, a protection structure, namely a backing plate, is usually provided below. The protection plate needs to occupy a certain space and will increase the weight and volume of the battery pack. For a vehicle, the increase in weight and volume may affect the vehicle's performance and driving range. The presence of the protection plate will increase the isolation layer at the bottom of the battery pack, restricting the transfer and dissipation of heat and affecting the heat dissipation effect of the battery pack.

[0003] Therefore, a new solution needs to be proposed to solve this problem. Summary of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a lithium battery pack with a protection structure. By providing a protective net at the bottom of the lithium battery, the presence of the protective net can provide better ventilation and heat dissipation effects. It allows air to flow freely and transfers the heat generated by the lithium battery to the surrounding environment better, helping to reduce the temperature of the lithium battery. This helps to maintain the normal operating temperature range of the lithium battery, improve performance and lifespan. Compared with the protection plate, the protective net is usually lighter and can reduce the overall weight of the lithium battery. This is beneficial for improving the energy efficiency and driving range of the vehicle.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: A lithium battery pack with a protection structure, including a fixing frame, characterized in that: a rectangular groove is opened at the upper end of the fixing frame, a protective net is movably connected inside the rectangular groove, several lithium batteries are placed on the upper end of the protective net, and a clamping block is provided at each of the four corners of the outer surface of the lithium battery, and the clamping block is fixedly connected to the protective net.

[0006] The utility model is further provided as: Two positioning bolts are movably inserted and connected to both the left end and the right end of the fixing frame.

[0007] The utility model is further provided as: Several through holes are opened at both the left end and the right end of the fixing frame.

[0008] The utility model is further provided as: The fixing frame is in a rectangular shape.

[0009] The utility model is further provided as: The clamping block is arranged in an L shape.

[0010] In summary, the utility model has the following beneficial effects:

[0011] 1. By setting a protective net at the bottom of the lithium battery, the presence of the protective net can provide better ventilation and heat dissipation. It allows air to flow freely and better transfer the heat generated by the lithium battery to the surrounding environment, which helps to reduce the temperature of the lithium battery. This helps to maintain the normal operating temperature range of the lithium battery, improve performance and life. Compared with the protective plate, the protective net is usually lighter and can reduce the overall weight of the lithium battery. This is beneficial to improving the energy efficiency and mileage of the vehicle. BRIEF DESCRIPTION OF THE DRAWINGS
