Description

Technical Field

[0001] The utility model relates to the technical field of new energy vehicles, and in particular to a battery temperature control device for new energy vehicles. Background Art

[0002] The battery temperature control device of new energy vehicles is an important device to ensure that the battery works within the optimal temperature range. New energy vehicle batteries will produce temperature differences during charging and discharging, and the batteries will generate heat when working. Especially during the charging and discharging process, the chemical reactions inside the battery will generate a lot of heat, causing the battery temperature to rise. This temperature difference will not only affect the performance of the battery, but also affect the battery's service life and safety. During the charging process, the battery voltage will gradually increase, and the charging current will also increase accordingly, which will cause more heat to be generated inside the battery, thereby causing the battery temperature to rise. During the discharging process, the battery voltage will gradually decrease, and the discharge current will also decrease accordingly, which will also cause heat to be generated inside the battery, thereby causing the battery temperature to rise. This temperature difference will not only affect the performance of the battery, but also affect the battery's service life and safety. Therefore, appropriate heat dissipation measures need to be taken to maintain the optimal temperature of the battery during operation, improve the battery's performance and safety, and extend the battery's service life.

[0003] Most of the existing battery temperature control devices for new energy vehicles use air cooling or water cooling. Both water cooling and air cooling can achieve a cooling effect. However, there are factors of bumps and vibrations when the car is driving. The temperature control method using water cooling may cause the water pipe to break and seal poorly due to vibration, which is more likely to cause leakage. At the same time, since the battery is inside the battery box and is in a closed state, the air flow cannot be evenly distributed inside the battery box through air cooling. In order to solve this technical problem, the utility model proposes a battery temperature control device for new energy vehicles. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-6As shown, a battery temperature control device for a new energy vehicle includes a battery box 1 and a filter box 5. A plurality of battery holders 2 are arranged inside the battery box 1. The batteries are installed and fixed by the battery holders 2. The cavities between the plurality of battery holders 2 form ventilation ducts 3 for air flow. The airflow flowing into the battery box 1 can be evenly distributed to various parts of the battery through the ventilation ducts 3. The battery holders 2 can suspend the bottom of the battery so that air passes through the bottom. A delivery pipe 4 is connected to one side of the battery box 1. A plurality of partitions 15 are arranged inside the delivery pipe 4. Both ends of the plurality of partitions 15 are connected to the inner wall of the delivery pipe 4, and the plurality of partitions 15 have an inclination angle. The flowing airflow can be divided by the partitions 15. Under the guidance of the partitions 15 with different inclination angles, the flowing airflow is evenly distributed to the inside of the battery box 1.

[0024] The other end of the delivery pipe 4 is connected to one side of the filter box 5. The interior of the filter box 5 is detachably connected with a filter screen 6. The filter box 5 can filter the air entering the battery box 1 through the filter screen 6 to prevent external dust from flowing into the battery box 1 along with the air. The other side of the filter box 5 is connected to a wide-angle cover 7, which can increase the amount of air flowing in.

[0025] The inner side of the wide-angle cover 7 is rotatably connected to a plurality of first rotating shafts 8, and the plurality of first rotating shafts 8 are arranged at equal distances, and the outer surfaces of the plurality of first rotating shafts 8 are connected to a first baffle 9. When there is no need to cool the battery, the air inlet of the wide-angle cover 7 can be closed by the first baffle 9 to block the inflow of external air. A control mechanism 10 is arranged on the outside of the wide-angle cover 7, and a support cover 11 is connected to the other side of the battery box 1. A fan 12 is installed inside the support cover 11. The rotation of the fan 12 can speed up the outflow of air from the battery box 1. After the fan 12 rotates, the air can be discharged to the outside, so that the inside of the battery box 1 is in a negative pressure state, thereby speeding up the inflow of external air into the battery box 1 and improving the circulation speed of the air inside the battery box 1.

[0026] The inner side of the support cover 11 is rotatably connected to a plurality of second rotating shafts 13, and the plurality of second rotating shafts 13 are arranged at equal distances, and the outer surfaces of the plurality of second rotating shafts 13 are connected to a second baffle 14. After the fan 12 stops rotating, a strong airflow cannot be generated, and the second baffle 14 cannot be blown to swing upward. Instead, it will swing downward under the influence of gravity, and after swinging downward, it will be in a vertical state, so that the air outlet of the support cover 11 can be closed, and external dust can be prevented from entering the interior of the battery box 1.

[0027] The opening and closing of the first baffle 9 is controlled by a control mechanism 10, and the control mechanism 10 includes a plurality of swing arms 1001, one end of each of the plurality of swing arms 1001 is connected to one end of the first rotating shaft 8 located outside the wide-angle cover 7, and the other end of the swing arm 1001 is connected to a connecting rod 1002 for fixed-point rotation. The first rotating shaft 8 is driven to rotate by changing the angle of the swing arm 1001, so that the first baffle 9 is opened and closed, and the swing arms 1001 are connected in series through the connecting rod 1002, so that the first baffle 9 is opened and closed synchronously, and a support seat 1003 is connected to one side of the wide-angle cover 7, and an electric telescopic rod 1004 is connected to the inner side of the support seat 1003 for fixed-point rotation. The output end of the electric telescopic rod 1004 is connected to one end of the connecting rod 1002 for fixed-point rotation, and the thrust generated by the electric telescopic rod 1004 provides power for moving the connecting rod 1002, and the electric telescopic rod 1004 converts the rotational motion of the internal motor into linear motion to provide thrust.

[0028] A retaining groove 16 is provided at one end of the first baffle plate 9, and a retaining block 17 is connected to the other end of the first baffle plate 9, and the retaining groove 16 is adapted to the retaining block 17. When air is not required to flow into the battery box 1, the partition 15 will swing downward to close the air inlet of the wide-angle cover 7 to prevent air from flowing in, and the retaining block 17 will be recessed into the groove, and the retaining block 17 can achieve a better sealing effect through the retaining groove 16.

[0029] It should be noted that in actual use of the device, the electric telescopic rod 1004 is first started to push the connecting rod 1002 to move its position. When the connecting rod 1002 moves its position, it drives the first baffle 9 to swing, and then opens the wide-angle cover 7 to allow air to flow into the battery box 1. The fan 12 is started to rotate. After the fan 12 rotates, the air inside the battery box 1 is drawn out to blow the second baffle 14 upward and swing it. After the air enters the conveying pipe 4, it is divided by the partition 15 and is evenly distributed to the inside of the battery box 1 under the guidance of the angle of the partition 15.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
