为防止电池组在充放电时温度过高，电池组常搭配散热装置使用，目前常用的散热方式是将散热片设置在电池模组的保护外壳上，然而为防止雨水等其他杂物直接接触电池，保护外壳常封闭设置，造成内部热量难以快速散发，紧靠散热片热转换散热效率低，长时间使用仍然会导致电池发烫等问题，实际散热效果差，故而提出了一种可变电流放电技术的磷酸铁锂电池组模块来解决上述问题。To prevent the battery pack from overheating during charging and discharging, the battery pack is often used with a heat dissipation device. The commonly used heat dissipation method is to set the heat sink on the protective shell of the battery module. However, in order to prevent rain and other debris from directly contacting the battery, the protective shell is often closed, which makes it difficult for the internal heat to dissipate quickly. The heat conversion and heat dissipation efficiency is low close to the heat sink. Long-term use will still cause problems such as battery heating, and the actual heat dissipation effect is poor. Therefore, a lithium iron phosphate battery pack module with variable current discharge technology is proposed to solve the above problems.

The motor 901 drives the driving gear 903 to rotate through the connecting rod 902, thereby driving the two driven gears 906 to rotate, and at the same time drives the first screw 904 and the second screw 905 to rotate. The first screw 904 and the second screw 905 drive the movable seat 907 to move left and right with the cooperation of the limit rod, so that the movable seat 907 supports and fixes the cooling fan 908 while driving the cooling fan 908 to move left and right, and cooperates with the thermal conductive base pad 3 and the cooling fins 6 to increase the heat dissipation area.
具体地，通过在安装框架804的左右两侧内壁之间固定连接有数量为三个的限位杆，三个移动座907分别与三个限位杆滑动连接，进而对移动座907进行导向限位，防止其跟随第一螺杆904和第二螺杆905转动。Specifically, three limit rods are fixedly connected between the left and right inner walls of the mounting frame 804, and the three movable seats 907 are slidably connected to the three limit rods respectively, thereby guiding and limiting the movable seats 907 to prevent them from rotating with the first screw 904 and the second screw 905.
综上所述，该可变电流放电技术的磷酸铁锂电池组模块，通过设置调节组件8，通过两个电动伸缩杆802，使得两个电动伸缩杆802的自由端同时伸长或收缩，进而带动两个第一铰接座803在导向块与导向槽的配合下进行相向移动或者相背移动，第一铰接座803移动的同时带动两个转动臂806向内或者向外转动，进而在第二铰接座805的配合下，带动安装框架804向上或者向下移动，进而调整散热组件9与电池模组的距离，根据需求调整散热风扇908与电池模组之间的距离，可以增加空气流动的时间和路径，使得热量能够更好地被带走，进而提高散热效果，同时散热风扇908通常会产生噪音，通过调节散热风扇908与电池模组之间的距离，可以改变空气流动的方式，减少噪音的传播，从而降低使用时的噪音干扰。In summary, the lithium iron phosphate battery pack module of the variable current discharge technology is provided with an adjustment component 8, through two electric telescopic rods 802, so that the free ends of the two electric telescopic rods 802 are extended or contracted at the same time, thereby driving the two first hinged seats 803 to move toward or away from each other under the cooperation of the guide block and the guide groove. When the first hinged seat 803 moves, it drives the two rotating arms 806 to rotate inward or outward, and then drives the mounting frame 804 to move upward or downward with the cooperation of the second hinged seat 805, thereby adjusting the distance between the heat dissipation component 9 and the battery module. By adjusting the distance between the heat dissipation fan 908 and the battery module as needed, the time and path of air flow can be increased, so that heat can be better taken away, thereby improving the heat dissipation effect. At the same time, the heat dissipation fan 908 usually generates noise. By adjusting the distance between the heat dissipation fan 908 and the battery module, the air flow mode can be changed, the noise propagation can be reduced, and the noise interference during use can be reduced.
并且，通过设置散热组件9，电机901通过连接杆902带动主动齿轮903转动，进而带动两个从动齿轮906转动，同时带动第一螺杆904和第二螺杆905转动，第一螺杆904和第二螺杆905在限位杆的配合下带动移动座907左右移动，进而使得移动座907在支撑固定散热风扇908的同时带动散热风扇908进行左右移动，从而可以增大散热面积，提高散热效率，解决了目前电池组常用的散热方式是将散热片设置在电池组的保护外壳上，然而为防止雨水等其他杂物直接接触电池，保护外壳常封闭设置，造成内部热量难以快速散发，紧靠散热片热转换散热效率低，长时间使用仍然会导致电池发烫等问题，实际散热效果差的问题。In addition, by setting up the heat dissipation component 9, the motor 901 drives the driving gear 903 to rotate through the connecting rod 902, and then drives the two driven gears 906 to rotate, and at the same time drives the first screw 904 and the second screw 905 to rotate. The first screw 904 and the second screw 905 drive the movable seat 907 to move left and right with the cooperation of the limit rod, so that the movable seat 907 drives the cooling fan 908 to move left and right while supporting the fixed cooling fan 908, thereby increasing the heat dissipation area and improving the heat dissipation efficiency, solving the problem that the commonly used heat dissipation method of the battery pack is to set the heat sink on the protective shell of the battery pack. However, in order to prevent rainwater and other debris from directly contacting the battery, the protective shell is often closed, which makes it difficult for the internal heat to be quickly dissipated, and the heat dissipation efficiency of the heat conversion close to the heat sink is low. Long-term use will still cause problems such as battery heating, and the actual heat dissipation effect is poor.
