In one of the preferred embodiments, the circulation assembly includes an intermediate gear 3 rotatably mounted on the inner top of the battery compartment 1, a plurality of rotation shafts 5 are rotatably mounted on the inner top of the battery compartment 1 around the intermediate gear 3, the outer walls of the rotation shafts 5 are respectively fixed with a transmission gear 4 meshed with the intermediate gear 3, the bottom of each rotation shaft 5 is respectively provided with a blowing fan 2, the blowing directions of each blowing fan 2 are the same, and a battery 18 is arranged at the center between the blowing fans 2.
The circulation assembly can refer to fig. 6, when the temperature is controlled by the cooperation of the heating plate 19 and the cooling assembly 21 in the battery compartment 1, the air in the battery compartment 1 is circulated and flowed through the plurality of blowing fans 2 arranged around the battery 18 in the same direction, namely clockwise or anticlockwise, so that the temperature of the heating plate 19 and the cooling assembly 21 in a local area is prevented from being too high or too low, and the temperature of each part in the battery compartment 1 is kept uniform, so that a constant temperature effect is provided for the battery 18.
In one preferred embodiment, the battery pack further comprises a connecting assembly, wherein the connecting assembly comprises a sliding bar 9 horizontally and slidably arranged at the top of the battery compartment 1, the tops of two sides of the battery compartment 1 are respectively fixed with a stop block 10 for limiting the sliding bar 9, one end of one stop block 10 opposite to the sliding bar 9 is respectively fixed with an electric connection sheet 11, and when the two electric connection sheets 11 are contacted, the charging and discharging equipment 20 is electrically connected with the battery 18 and is used for charging or discharging;

The connection assembly is used for controlling whether the charge and discharge equipment 20 and the battery 18 are electrically connected or not, and the operation is specifically as follows, the rotating rod 14 is driven to rotate by an external mechanism, such as a motor, and then the sliding block 13 is driven to reciprocate under the action of the connecting rod 15, when the sliding block 13 slides to be contacted with one of the convex blocks 12, the sliding block 13 drives the sliding strip 9 to slide at the moment, so that the purpose of driving the sliding strip 9 to reciprocate in a stop mode is achieved;
when the sliding bar 9 slides to one side, the electric contact sheet 11 on the sliding bar contacts with the electric contact sheet 11 on one of the stop blocks 10, so as to complete the electric connection between the charge and discharge equipment 20 and the battery 18, and complete the charge or discharge of the battery 18 and the detection process of the current detection component 22;
on the contrary, when the sliding bar 9 moves to separate the two electric connection pieces 11 from each other, the battery 18 is powered off, so that the battery 18 is continuously and intermittently electrified by the intermittent reciprocating movement of the sliding bar 9, and the purpose of doing so is to silence the middle of the battery 18 for a period of time and perform heat exchange with the temperature in the battery compartment 1, so as to ensure that the ambient temperature of the battery 18 is the same as the temperature of the battery 18, and because the battery 18 generates certain heat in the process of charging or discharging, if the battery 18 is detected in a low-temperature state, after a period of charging or discharging, the temperature in the battery compartment 1 is lower than the temperature of the battery 18 due to the heat generated by the battery 18, so that the current and the voltage generated by the battery 18 can influence the charging or discharging of the battery 18, thereby increasing other variables and further causing errors in the detection result to reduce the detection accuracy;
therefore, by intermittently powering on the battery 18, a period of silence is provided in the middle of the battery 18, and heat exchange is performed with the temperature in the battery compartment 1 during the period of time, so as to ensure that the temperature of the battery 18 and the ambient temperature are fully heat exchanged, further avoid errors of temperature generated by the battery 18 on charge and discharge detection, and improve detection accuracy.
In one preferred embodiment, the top of the battery compartment 1 is further provided with an adjusting component, the adjusting component comprises a first gear 6 rotatably installed at the top of the battery compartment 1 and coaxially fixed with the intermediate gear 3, the top of the battery compartment 1 is rotatably provided with a sector gear 7 meshed with the first gear 6, the outer wall of the sector gear 7 is fixedly provided with an elastic telescopic rod 8, and the telescopic end of the elastic telescopic rod 8 is rotatably connected with the outer wall of the sliding strip 9.
The adjusting assembly can refer to fig. 1 and 5, when the sliding bar 9 slides reciprocally under the driving of the sliding block 13, the sliding bar 9 drives the elastic telescopic rod 8 to rotate, so as to drive the sector gear 7 to rotate, and then drive the first gear 6 to rotate, when the first gear 6 rotates, the middle gear 3 rotates along with the middle gear 3, and a structure of a planetary gear is formed between the plurality of transmission gears 4 and the middle gear 3, so that the plurality of transmission gears 4 rotate in the same direction, and drive the rotating shaft 5 and the blowing fan 2 at the bottom of the rotating shaft to rotate 90 degrees together to face the battery 18, at this moment, the internal circulation direction in the battery compartment 1 is changed into longitudinal circulation by the transverse circulation direction, and the blowing fan 2 blows ambient hot air or cold air directly on the battery 18, so as to further accelerate the heat exchange between the battery 18 and the air temperature in the battery compartment 1, so that the battery 18 keeps balance with the battery compartment 1 in the time, and when the battery 18 is powered on again, the ambient temperature where the battery 18 is located can be guaranteed, thereby avoiding the influence of the heat generated by the battery 18 itself on the detection result, and improving the detection accuracy.
It should be noted that, when the elastic telescopic rod 8 rotates along with the sliding rod 9, it will firstly perform elastic compression until the elastic telescopic rod rotates beyond the compressed shortest position, and the elastic force of the elastic telescopic rod 8 will quickly recover, so as to drive the sliding rod 9 to complete subsequent movement, and since the sliding block 13 is located between the two protruding blocks 12, the sliding rod 9 will not affect the sliding block 13 in the process of completing subsequent movement, so that the sliding distance of the sliding block 13 only needs to push the protruding blocks 12 to drive the elastic telescopic rod 8 to rotate beyond the compressed shortest position, and the angle of each time the sector gear 7 drives the first gear 6 is fixed, so as to ensure that the rotation range of the blowing fan 2 is 90 degrees.
In one of the preferred embodiments, the heating plates 19 are provided with four, the four heating plates 19 are all provided in a cambered shape, and the four heating plates 19 are respectively installed at four corners of the battery compartment 1.
The heating plate 19 can be seen in fig. 5-6, and on one hand, the heating uniformity can be improved by arranging the heating plate at four corners, and on the other hand, the cambered surface-shaped arrangement of the heating plate can also play a role in guiding the air circulated by the blowing fan 2, so that the smoothness of the internal air circulation is quickened, and the kinetic energy loss during the air circulation is reduced.
In one of the preferred embodiments, the rotation shaft 5 is provided as a telescopic rod of adjustable length.
By setting the rotation shaft 5 to be adjustable in length, the height of the blowing fan 2 can be adjusted so as to adapt to batteries 18 with different heights and different temperature environments, when the temperature in the battery compartment 1 is higher than the temperature of the batteries 18, the rotation shaft 5 can be adjusted so that the blowing fan 2 moves to a position where the batteries 18 are close to the upper side, thus the air contacting the batteries 18 in the longitudinal circulation is circulated from top to bottom, which is beneficial to blowing the hot air above downwards, and conversely, when the temperature in the battery compartment 1 is lower than the temperature of the batteries 18, the rotation shaft 5 is adjusted so that the blowing fan 2 moves to a position close to the lower side of the batteries 18, thus the air circulates from bottom to top, which is beneficial to blowing the cold air below upwards.
But also facilitates the insertion and removal of the battery 18 by adjusting the height of the blowing fan 2.
In one preferred embodiment, the outer wall of the rotating rod 14 is provided with a long groove, the adjusting block 16 is slidably mounted in the long groove, the inner wall of the long groove is rotatably provided with a screw 17 extending out of the rotating rod 14, and the screw 17 penetrates through the adjusting block 16 and is in threaded connection with the penetrating position of the adjusting block 16.
As can be seen from the above description, the sliding distance of the slider 13 only needs to push the bump 12 to drive the elastic telescopic rod 8 to rotate beyond the compressed shortest position, so when the rotating screw 17 drives the adjusting block 16 to move, the moving distance of the rotating rod 14 to drive the slider 13 through the connecting rod 15 also changes, when the moving distance of the slider 13 becomes smaller, the moving speed of the slider 13 becomes faster, so the frequency of the slider 13 contacting the bump 12 and driving the sliding bar 9 to reciprocate becomes faster, thus the silence time equivalent to the battery 18 is shortened, otherwise, the silence time of the battery 18 is prolonged, so the adjusting distance of the adjusting block 16 can be controlled according to the size of the battery 18, the silence time of the small battery 18 is shorter, and the silence time of the large battery 18 is longer, thereby not only ensuring the silence time of the battery 18 to perform heat exchange, but also adapting to the batteries 18 of different sizes, thereby reducing the time of the detection interval and improving the detection efficiency.
The second embodiment of the present utility model is substantially the same as the first embodiment except that a second implementation of the adjustment assembly is provided, see in particular fig. 9;
in one of the preferred embodiments, the top of the battery compartment 1 is further provided with an adjusting component, the adjusting component comprises a second gear 25 rotatably installed at the top of the battery compartment 1 and coaxially fixed with the intermediate gear 3, a swing rod 26 is coaxially fixed to the second gear 25, the swing rod 26 is far away from the sliding strip 9, limiting pins 23 for limiting the swing rod 26 are fixed to the top of the battery compartment 1 located at two sides of the swing rod 26, and a tension spring 24 is connected between the outer wall of the swing rod 26 far away from the second gear 25 and the sliding strip 9.
As can be seen from the above description, the sliding bar 9 is intermittently connected by the intermittent reciprocating movement, and the sliding bar 9 is moved while being driven by the tension of the tension spring 24, the swing rod 26 rotates, then the swing rod 26 drives the second gear 25 to rotate, and the second gear 25 drives the intermediate gear 3 to rotate, so as to achieve the purpose of adjusting the blowing direction of the blower fan 2.
