Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

Referring to Figures 1-2, a battery temperature control device based on ambient temperature changes includes an outer shell 1, a positioning seat 2 is fixedly connected to the bottom surface of the inner cavity of the outer shell 1, and an inner shell 3 is fixedly installed on the positioning seat 2; the top surfaces of the outer shell 1 and the inner shell 3 are transparent, a heating component is fixedly installed on the bottom surface of the inner cavity of the outer shell 1, and a plurality of fans 4 are symmetrically fixedly installed on two opposite side walls of the inner shell 3, and ventilation holes 5 are opened on the side walls of the outer shell 1 at positions corresponding to the fans 4, a cover plate 6 is detachably installed on the top of the outer shell 1, and two conductive columns 7 are vertically penetrated by the cover plate 6, and the bottom ends of the conductive columns 7 pass through the cover plate 6 from top to bottom and are fixedly connected to a conductive sheet 8; a plurality of electronic thermometers 9 are installed on the side walls of the inner cavity of the outer shell 1.

The shapes of the outer shell 1 and the inner shell 3 can be adjusted accordingly according to the shape of the battery, so that the battery can be placed exactly in the inner shell 3; the positioning seat 2 can fix the position of the inner shell 3 in the outer shell 1, and the inner shell 3 will not be misplaced, so that the outer wall of the inner shell 3 is always at a certain distance from the inner wall of the outer shell 1; the heating component can heat the inside of the outer shell 1 when the ambient temperature is low, and the heat will be transferred to the inside of the inner shell 3 through the inner shell 3, so that the temperature in the inner shell 3 increases; the fans 4 located on different side walls of the inner shell 3 rotate in different directions, forming a fan 4 on one side wall The air is sucked in from the outside to the inside, and the fan 4 on the other opposite side wall exhausts air from the inside to the outside. In this way, a flowing airflow is formed in the inner shell 3, which can take away the heat inside the inner shell 3 and reduce the temperature inside the inner shell 3. The ventilation holes 5 on the outer shell 1 can ensure the normal circulation of air inside and outside the device. The cover plate 6 can cover the top surfaces of the outer shell 1 and the inner shell 3, and wrap and seal the battery in the inner shell 3. The positions of the two conductive columns 7 correspond to the positions of the two poles of the battery. The conductive columns 7 are in contact with the two poles of the battery through the conductive sheet 8. In this way, the battery The electric energy can be output to the outside through the conductive column 7, and the external electrical equipment only needs to be connected to the conductive column 7; preferably, four electronic thermometers 9 are arranged in groups of two in the outer shell 1 in a spatial diagonal manner, so that the temperature inside the outer shell 1 can be fully measured to prevent measurement errors caused by measuring only local temperatures; the electronic thermometers 9, the fan 4 and the heating component are evenly electrically connected to the external control system to realize automatic control, and several electronic thermometers 9 monitor the temperature changes of the inner cavity of the outer shell 1 in real time, and transmit the recorded values to the control system. The control system calculates the values of all electronic thermometers 9, takes the average to determine the average temperature inside the outer shell 1, and compares it with the set appropriate temperature. When the monitored temperature is higher than the set temperature, the control system sends an instruction to the fan 4 to start the fan 4, form an airflow in the inner shell 3, take away the internal heat, and reduce the temperature. When the temperature is lower than the set temperature, the control system sends a stop signal to the fan 4, and then starts the heating component to heat the inner shell 1 to increase the temperature. Through such operation, the battery can always be kept at a suitable temperature.

According to a further optimized solution, the heating assembly includes a heating plate 10 fixedly mounted on the bottom surface of the inner cavity of the outer shell 1 , a heat conducting plate 11 is fixedly connected to the top surface of the heating plate 10 , and the top surface of the heat conducting plate 11 abuts against the bottom surface of the inner shell 3 .

The heating plate 10 is electrically connected to an external control system and can generate heat when powered on. The heat conducting plate 11 can transfer the heat generated by the heating plate 10 to the inner shell 3 more evenly, while preventing the heating plate 10 from directly contacting the inner shell 3, resulting in high temperatures at local locations of the inner shell 3 and low temperatures at other locations, resulting in excessive temperature differences.

According to a further optimized solution, a cylinder 12 is passed through the ventilation hole 5 , and a filter cloth 13 is fixedly connected to the cylinder 12 .

The filter cloth 13 can filter the air entering the inner cavity of the housing 1, intercept impurities in the air, and ensure the cleanliness of the interior of the device.

According to a further optimized solution, a plurality of support blocks 14 are fixedly connected to the bottom surface of the inner cavity of the inner shell 3 , and a plurality of stop blocks 15 are fixedly connected to the inner cavity side wall of the inner shell 3 along the circumferential direction.

Several support blocks 14 are arranged in a matrix, which can stably support the battery, thereby separating the bottom of the battery from the bottom of the inner cavity of the inner shell 3, and the block 15 can separate the side wall of the battery from the side wall of the inner shell 3. In this way, under the joint action of the support block 14 and the block 15, there are gaps between the bottom surface and the side wall of the battery and the inner shell 3, and the airflow generated by the fan 4 will flow evenly around the battery, which can cool the battery more evenly.

According to a further optimized solution, the edge of the cover plate 6 is detachably connected to the side wall of the housing 1 via a plurality of lock buckles 16 .

The lock buckle 16 is an existing item and has been widely used in luggage and other items. The lock buckle 16 can detachably connect the cover plate 6 to the housing 1, making it convenient to replace and repair the battery.

According to a further optimized solution, a wing plate 17 is formed extending around the end surface of the cylinder 12 close to the outside, and the wing plate 17 is detachably connected to the side wall of the housing 1 by bolts.

The cylinder 12 and the wing plate 17 are integrally formed, and the wing plate 17 is fixed to the housing 1 by bolts, so that the cylinder 12 can be fixed and the wing plate 17 is convenient for disassembly and replacement.

When using the utility model, the cover plate 6 is opened, the battery is placed in the inner shell 3, the cover plate 6 is closed, and then the electronic thermometer 9, the fan 4 and the heating plate 10 are electrically connected to the external control system, and then the two conductive columns 7 are connected to the external electrical equipment before normal use. All electronic thermometers 9 will monitor the temperature changes in the outer shell 1 in real time, and then transmit the monitored temperature value to the control system. The control system calculates the average temperature and compares it with the set appropriate temperature value. If it is higher than the set value, the fan 4 is turned on for cooling. If it is lower than the set value, the heating plate 10 is turned on for heating. In this way, the battery is not affected by changes in the external ambient temperature and is always at a suitable temperature.
