The heat dissipation grilles can allow air to pass through the energy storage battery cells to achieve a heat dissipation effect. However, the heat dissipation grilles also cause external dust to enter the interior of the energy storage battery cells when the energy storage battery cells are in a non-working state, resulting in abnormal heating, short circuit, and fire when the energy storage battery cells are working.

[0014] The adjustment structure further includes a power member arranged on the mounting plate. A plurality of support rods are installed on the power member at equal circumferential intervals. One end of the support rod far from the power member is connected to the telescopic plate member.

[0015] As a further solution of the present invention: The telescopic plate member includes a guiding member connecting the rotating shaft. The guiding member has a "C"-shaped structure. A telescopic plate is slidably installed inside the guiding member. One end of the telescopic plate far from the rotating shaft is connected to the arc-shaped member. And the telescopic plate is rotatably connected to the support rod.

[0016] As a further solution of the present invention: The power member includes an electric telescopic rod fixedly installed on the mounting plate and a first sliding sleeve slidably sleeved on the rotating shaft. The first sliding sleeve is rotatably connected to one end of the support rod far from the telescopic plate. And a collar is rotatably installed on the first sliding sleeve. The collar is connected to the operating end of the electric telescopic rod;

[0017] The electric telescopic rod is electrically connected to a temperature sensor arranged inside the battery cell body.

[0018] As a further solution of the present invention: The plugging assembly includes two plugging plates slidably attached to the inner side of the battery cell body. A plurality of guiding through holes adapted to the air inlet holes are arranged on the plugging plates at equal intervals;

[0019] The two plugging plates are connected by a connecting plate. And one of the plugging plates is connected to the centrifugal assembly;

[0020] The plugging assembly further includes an elastic support structure connecting the battery cell body and the plugging plate.

[0021] As a further solution of the present invention: The elastic support structure includes a telescopic rod member connecting the plugging plate and the battery cell body. A cylindrical spring is sleeved on the telescopic rod member. One end of the cylindrical spring is connected to the plugging plate, and the other end is connected to the battery cell body.

[0022] As a further solution of the present invention: The centrifugal assembly includes a connecting shaft rotatably installed on the mounting plate. One end of the connecting shaft is connected to the rotating shaft of the impeller through a bevel gear set;

[0023] A plurality of groups of followers arranged in a circumference are also slidably mounted on the connecting shaft. The followers are provided with sliding grooves along their length directions. The connecting structures arranged on the sliding grooves and the connecting shaft are connected to the blocking plate.

[0024] As a further solution of the present invention: the connection structure comprises a sliding block slidably mounted in the sliding groove and a second sliding sleeve slidably mounted on the connecting shaft, a transverse plate rotatably mounted on the second sliding sleeve, and the transverse plate is connected to the blocking plate;

[0026] A method for using the energy storage battery core heat dissipation structure as described above comprises the following steps:

[0027] Step 1: When the temperature inside the battery cell drops below a preset value during use, the drive assembly stops working and the air inlet is blocked, so that the battery cell is in a closed state, isolating the outside and preventing the battery cell from being too cold.

[0028] Step 2: When the temperature inside the battery cell body is higher than the preset value, the driving component will be activated to drive the two impellers to rotate. At the same time, under the action of the centrifugal component, the blocking component is driven to operate, so that the air inlet hole is connected, and the external air can enter the battery cell body;

[0029] Step 3: When the temperature inside the battery cell body is higher than the preset value and the temperature is still rising, the adjustment structure moves to increase the radius of the transmission wheel, thereby increasing the speed of the impeller and increasing the amount of air flowing through the battery cell body.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] By setting the driving assembly, the temperature sensor can detect the temperature inside the battery body in real time, and selectively control the driving device to work according to the real-time temperature value, so as to realize automatic cooling when the temperature inside the battery body is too high, and maintain the stable operation of the battery body, and when the temperature inside the battery body continues to rise, the electric telescopic rod can move, so that the radius of the pulley formed by the multiple arc-shaped parts is increased, thereby increasing the speed of the impeller, increasing the power of the sucked air, and further improving the heat dissipation effect;

[0032] Through the provided plugging component, on the one hand, when the temperature of the battery cell body is relatively low, the heat generated by the battery cell body itself can be utilized to increase the operating temperature of the battery cell body, enabling the battery cell body to quickly reach its preset operating temperature. On the other hand, when the temperature of the battery cell body is relatively low or the battery cell body is in a non-operating state, it can prevent external dust from entering the battery cell body, which may cause abnormal heat generation, short circuit, and fire during the operation of the battery cell body, further improving the operating stability of the battery cell body;

[0033] Through the provided centrifugal component, when the impeller rotates, it can drive the slider and the counterweight to perform circular motion, thereby generating centrifugal force, and driving the plugging plate to move through the second sliding sleeve, making the guide through-hole coincide with the air inlet hole. At this time, when the impeller rotates, it can draw external air into the battery cell body, realizing the linkage control between the plugging plate and the impeller, and improving the degree of integration.

[0045] In addition, an element in the present invention is referred to as being "fixed to" or "disposed on" another element, and it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation manner.

[0046] Please refer to Figures 1 to 9 , in the embodiment of the present invention, a heat dissipation structure for an energy storage battery cell is provided inside the battery cell body 1, including: an impeller 6, a driving assembly, a sealing assembly and a centrifugal assembly. On the one hand, when the temperature of the battery cell body 1 is relatively low, the heat generated by the battery cell body 1 itself can be utilized to increase the working temperature of the battery cell body 1, so that the preset working temperature can be quickly reached inside the battery cell body 1. On the other hand, it can prevent external dust from entering the battery cell body 1, which may cause abnormal heating and short-circuit fire of the battery cell body 1, and further improve the operation stability of the battery cell body 1, specifically as follows:

[0047] Two groups of the impellers 6 are provided and installed inside the battery cell body 1, and the two groups of the impellers 6 are connected by a second belt 17;

[0048] The folding plate 4 is installed inside the battery cell body 1.

[0049] During use, the rotation of the impeller 6 can draw external air into the battery cell body 1. At the same time, the folding plates 4 are arranged in multiple groups in a triangular shape, enabling the air entering the battery cell body 1 to be dispersed, so that the air can evenly pass through the battery cell body 1, thereby improving the cooling effect on the battery cell body 1.

[0050] The driving assembly is arranged inside the battery cell body 1. The assembly includes an adjusting structure and multiple arc-shaped members 14 arranged in a circle. The arc-shaped members 14 form a transmission wheel. The transmission wheel is connected to the rotating shaft of one of the impellers 6 through a first belt 16, and the adjusting structure can change the circumferential radius of the transmission wheel.

[0051] The adjusting structure includes a mounting plate 5 fixedly installed on the battery cell body 1. A driving device 7 is fixedly installed on the mounting plate 5. A rotating shaft 9 is coaxially arranged on the output shaft of the driving device 7. Multiple telescopic plate members are arranged on the rotating shaft 9 at equal circumferential intervals. The telescopic plate members are connected to the arc-shaped members 14.

[0052] The adjusting structure further includes a power member arranged on the mounting plate 5. Multiple support rods 12 are installed on the power member at equal circumferential intervals. One end of the support rod 12 away from the power member is connected to the telescopic plate member.

[0053] The telescopic plate member includes a guiding member 15 connected to the rotating shaft 9. The guiding member 15 is in a "C" shape, and a telescopic plate 13 is slidably installed inside the guiding member 15. One end of the telescopic plate 13 away from the rotating shaft 9 is connected to the arc-shaped member 14, and the telescopic plate 13 is rotatably connected to the support rod 12.

[0054] The power member includes an electric telescopic rod 8 fixedly installed on the mounting plate 5 and a first sliding sleeve 10 slidably sleeved on the rotating shaft 9. The first sliding sleeve 10 is rotatably connected to one end of the support rod 12 away from the telescopic plate 13, and a collar 11 is rotatably installed on the first sliding sleeve 10. The collar 11 is connected to the moving end of the electric telescopic rod 8.

[0055] The electric telescopic rod 8 is electrically connected to a temperature sensor arranged inside the battery cell body 1.

[0056] In the initial state, the driving device 7 is in a non-operating state. When the battery cell body 1 operates and the temperature rises, when the temperature inside the battery cell body 1 is higher than the preset value, the temperature sensor will control the driving device 7 to work. At this time, the output shaft of the driving device 7 drives multiple arc-shaped members 14 to rotate through the rotating shaft 9, and drives the impeller 6 to rotate through the first belt 16, so as to automatically cool down when the temperature inside the battery cell body 1 is too high and maintain the stable operation of the battery cell body 1.

[0057] When the temperature inside the battery cell body 1 continues to rise after the driving device 7 starts working, the moving end of the electric telescopic rod 8 will extend outwards. At this time, the collar 11 connected thereto will drive the first sliding sleeve 10 to move along the length direction of the rotating shaft 9. At this time, the first sliding sleeve 10 drives the telescopic plate 13 to move away from the rotating shaft 9 along the length direction of the guiding member 15 through the support rod 12, so that the pulley radius formed by the plurality of arc-shaped members 14 increases. When the rotational speed of the driving device 7 is constant, the rotational speed of the impeller 6 can be increased, thereby increasing the power of sucking air and improving the heat dissipation effect.

[0058] It should be noted that the above-mentioned first belt 16 is made of an elastic material to prevent the first belt 16 from breaking when the pulley radius formed by the plurality of arc-shaped members 14 increases.

[0059] Through the above settings, the temperature sensor can detect the temperature inside the battery cell body 1 in real time and selectively control the driving device 7 to work according to the real-time temperature value. Thus, when the temperature inside the battery cell body 1 is too high, automatic cooling is realized to maintain the stable operation of the battery cell body 1. And when the temperature inside the battery cell body 1 continues to rise, the electric telescopic rod 8 can act, so that the pulley radius formed by the plurality of arc-shaped members 14 increases, thereby increasing the rotational speed of the impeller 6 and the power of sucking air, and further improving the heat dissipation effect.

[0060] Please refer to Figure 3 、 Figure 5 、 Figure 8 , the plugging assembly is arranged inside the battery cell body 1, and the plugging assembly is used to plug the air inlet hole 101 arranged on the side of the battery cell body 1;

[0061] The plugging assembly includes two groups of plugging plates 2 that are slidably attached to the inner side of the battery cell body 1. A plurality of groups of through holes 201 adapted to the air inlet holes 101 are equidistantly arranged on the plugging plates 2;

[0062] The two groups of plugging plates 2 are connected by a connecting plate 3, and one group of plugging plates 2 is connected to the centrifugal assembly;

[0063] The plugging assembly further includes an elastic support structure connecting the battery cell body 1 and the plugging plate 2. The elastic support structure includes a telescopic rod member 26 connecting the plugging plate 2 and the inside of the battery cell body 1. A cylindrical spring 27 is sleeved on the telescopic rod member 26. One end of the cylindrical spring 27 is connected to the plugging plate 2, and the other end is connected to the battery cell body 1.

[0064] In the initial state, the cylindrical spring 27 is in a compressed state. At this time, the guide through hole 201 on the plugging plate 2 is misaligned with the air inlet hole 101, forming a sealed space inside the battery cell body 1. On the one hand, when the temperature of the battery cell body 1 is relatively low, the heat generated by the battery cell body 1 itself can be used to increase the operating temperature of the battery cell body 1, enabling the battery cell body 1 to quickly reach its preset operating temperature. On the other hand, when the temperature of the battery cell body is relatively low or the battery cell body is in a non-operating state, it can prevent external dust from entering the battery cell body 1, avoiding abnormal heat generation, short circuit and fire during the operation of the battery cell body 1, and further improving the operating stability of the battery cell body 1.

[0065] Please refer to Figure 5 、 Figures 8 to 9 The centrifugal component is connected to the rotating shaft of the other set of impellers 6. When the centrifugal component operates, it can drive the plugging component to operate, thereby opening the air inlet hole 101.

[0066] The centrifugal component includes a connecting shaft 19 rotatably installed on the mounting plate 5. One end of the connecting shaft 19 is connected to the rotating shaft of the impeller 6 through a bevel gear set 18.

[0067] A plurality of groups of follower members 20 arranged in a circle are also slidably installed on the connecting shaft 19. A chute 2001 is formed along the length direction of the follower member 20. The connecting structure provided in the chute 2001 and the connecting shaft 19 is connected to the plugging plate 2. The connecting structure includes a slider 21 slidably installed in the chute 2001 and a second sliding sleeve 24 slidably installed on the connecting shaft 19. A horizontal plate 25 is rotatably installed on the second sliding sleeve 24, and the horizontal plate 25 is connected to the plugging plate 2.

[0068] A counterweight 22 is fixedly installed on one side of the slider 21, and a pull rod 23 is rotatably installed on the other side. The end of the pull rod 23 away from the slider 21 is rotatably connected to the second sliding sleeve 24.

[0069] When the radius of the pulley formed by the plurality of arc-shaped members 14 is the smallest, the impeller 6 can drive the connecting shaft 19 to rotate through the bevel gear set 18, causing the follower member 20 to perform a circular motion. At this time, the slider 21 and the counterweight 22 will also follow to perform a circular motion and generate centrifugal force. Under the action of the centrifugal force, the slider 21 will move away from the connecting shaft 19 along the length direction of the chute 2001, and pull the second sliding sleeve 24 to move along the length direction of the connecting shaft 19 towards the follower member 20 through the pull rod 23, driving the plugging plate 2 to move. While compressing the cylindrical spring 27, the guide through hole 201 coincides with the air inlet hole 101. At this time, the rotation of the impeller 6 can draw external air into the battery cell body 1, realizing the linkage control between the plugging plate 2 and the impeller 6 and improving the degree of integration.

[0070] With the above settings, when the impeller 6 rotates, it can drive the slider 21 and the counterweight 22 to perform circular motion, thereby generating centrifugal force, and driving the plugging plate 2 through the second sliding sleeve 24, so that the guide through hole 201 coincides with the air inlet hole 101. At this time, when the impeller 6 rotates, it can draw external air into the battery cell body 1, realizing the linkage control between the plugging plate 2 and the impeller 6, and improving the degree of integration.

[0071] As an embodiment of the present invention, a method for using the energy storage battery cell heat dissipation structure is also proposed, including the following steps:

[0072] Step 1: During use, when the temperature in the battery cell body 1 drops below the preset value, the driving component is in a stopped working state, and at this time, the air inlet hole 101 is in a blocked state, so that the battery cell body 1 is in a closed state, which can isolate the outside and prevent the battery cell body 1 from being at a low temperature;

[0073] Step 2: When the temperature in the battery cell body 1 is higher than the preset value, the driving component will act at this time, driving the two impellers 6 to rotate. At the same time, under the action of the centrifugal component, the plugging component is driven to act, and the air inlet hole 101 is conducted. At this time, external air can enter the battery cell body 1;

[0074] Step 3: When the temperature in the battery cell body 1 is higher than the preset value and the temperature continues to rise, the adjusting structure acts to increase the radius of the transmission wheel, and the rotation speed of the impeller 6 increases, increasing the amount of air flowing through the battery cell body 1.
