Technical Field

[0001] The utility model relates to the field of new energy vehicles, and in particular to a new energy vehicle battery fixing device with a heat dissipation function. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional automotive fuels as their power source and integrate advanced technologies in vehicle power control and drive. New energy vehicles are powered by multiple batteries. When installing the batteries, a battery fixture is required for fixation. The battery fixture refers to a device used to fix and protect the battery pack in the electric vehicle to ensure the stability and safety of the battery pack during driving. Existing fixtures usually use a closed frame structure combination to clamp and fix the battery during use. Since the car battery is prone to generate heat during use, the frame structure is prone to limit the heat dissipation of the battery pack, making it difficult to transfer the heat out in time, resulting in overheating and damage to the battery under long-term use and high-load working conditions, affecting the battery's performance and life; so we propose a new energy vehicle battery fixture with heat dissipation function to solve the above-mentioned problems. Utility Model Content

[0003] In order to overcome the existing fixing device, since the automobile battery is prone to generate heat during use, the frame structure is prone to limit the heat dissipation of the battery pack, making it difficult to transfer the heat out in time, resulting in the battery overheating and damage under long-term use and high-load working conditions, affecting the battery performance and life.

[0005] Preferably, the cooling tube is clamped and cooled along the outer end of the connecting frame by multiple sets of clamp rings, so that the cooling tube fits tightly to the surface of the battery, the heat transfer is more efficient, more uniform heat dissipation is achieved, local overheating and temperature unevenness are avoided, and the stable working state of the battery is maintained. The driving motor is used to drive the heat fan blades to rotate to assist the cooling of the cooling tube. When the heat fan blades rotate, the air circulation can be enhanced. At the same time, the rotation speed of the heat fan blades can be adjusted to achieve precise control of battery cooling to meet different heat dissipation requirements. The flow exchange pipeline is used to discharge the rising heat and then introduce the cold flow to promote the rapid heat dissipation. Rapid discharge further reduces the temperature of the battery, prevents internal heat from being difficult to discharge, effectively reduces the consumption of coolant, and reduces energy consumption. By rotating the screw, multiple groups of pressure plates are pushed to the upper end of the battery for fit and fixation, and pressure is evenly applied to the upper end of the battery to ensure that the battery pack is tightly fixed in the fixing device to prevent the battery pack from loosening or moving. The rebound spring rebound limit plate is used to clamp and fix the battery to achieve compact installation of the battery pack. At the same time, a certain buffering effect is provided to reduce the vibration and impact of the battery during vehicle driving, effectively protect the battery, and extend the service life of the battery.

[0010] Preferably, the cover plate is fixed with the connecting frame, and a ventilation groove for the exchange of cold and warm air is opened at the upper edge of the cover plate. The ventilation groove is used to assist the replacement of cold and warm air flows, thereby effectively guiding external fresh air into the battery pack to replace the hot air around the battery pack, thereby lowering the internal temperature, maintaining the thermal balance of the battery pack, avoiding overheating or overcooling, and reducing system failures and damage.

[0011] Preferably, the rebound spring is located on the inner wall of the connecting frame, and multiple groups of rebound springs are provided. A limit plate is provided at one end of the multiple groups of rebound springs away from the connecting frame, and a spring damper is provided on the inner side of the rebound spring.
