Description

Technical Field

[0001] The present invention relates to the technical field of battery power acquisition devices, and specifically to a lightweight high-energy power battery. Background Art

[0002] A power vehicle refers to a vehicle equipped with a power source. The power source of an electric power vehicle is a power battery pack. After continuous use, the power battery pack will generate a certain amount of heat by itself. If the heat is too high, there will be a greater safety hazard. Therefore, a heat dissipation structure is required for heat dissipation when the power battery pack is in use. When the existing heat dissipation structure of the power battery pack is in use, in order to prevent dust from entering the power battery pack, a dust filter screen is usually set at the position of the heat dissipation holes. However, as the use time of the dust filter screen increases, dust clogging is likely to occur on it, which is rather troublesome to clean, and the heat dissipation effect of the battery pack will be affected after clogging. Summary of the Invention

[0003] To solve the above technical problems, the present invention provides a lightweight high-energy power battery, including a heat dissipation mechanism. The heat dissipation mechanism further includes a protective shell. A sliding plate one is slidably connected to the inner wall of the protective shell. A connecting frame is fixedly connected to the bottom of the sliding plate one. Two ventilation grooves are opened in the inner wall of the sliding plate one.

[0004] A cooling mechanism, the cooling mechanism includes two fixed frames fixedly connected to the bottom of the connecting frame. A sliding plate three is slidably connected to the inner wall of each of the two fixed frames. A spring return rod two is fixedly connected to the side wall of each of the two sliding plates three.

[0005] A swing mechanism, the swing mechanism includes four fixed sleeves fixedly connected to the bottom of the sliding plate one. An oil delivery pipe one penetrates through the side wall of each of the four fixed sleeves. An extrusion plate is slidably connected to the inner wall of each of the four fixed sleeves. Hydraulic oil one is provided in the inner wall of each of the four fixed sleeves. Hydraulic oil two is provided in the inner wall of each of the four oil delivery pipes one.

[0006] Preferably, the heat dissipation mechanism further includes an electric telescopic rod fixedly connected to the top of the protective shell. The bottom output end of the electric telescopic rod is fixedly connected to the top of the sliding plate one. A lithium battery pack is fixedly connected to the bottom of the inner wall of the protective shell. A collector is fixedly connected to the bottom of the inner wall of the protective shell.

[0007] Among them, a heat expansion bag is fixedly connected to the side wall of the lithium battery pack. A start switch is fixedly connected to the inner wall of the protective shell. The staff installs the collector and the lithium battery pack together. The collector collects and displays the power in the lithium battery pack, reminding the staff of the remaining power in the lithium battery pack. When the lithium battery pack discharges, the generated heat will be transferred to the heat expansion bag, causing the heat expansion bag to expand due to heat. When the heat generated by the lithium battery pack is relatively high, the expansion amplitude of the heat expansion bag will become larger and contact the start switch.

[0008] Preferably, the heat dissipation mechanism further includes two blocking plates slidably connected to the bottom of the first sliding plate. At the side walls of the two blocking plates, there are fixedly connected first spring return rods. The outer walls of the two first spring return rods are both slidably connected to the bottom of the first sliding plate. At the inner wall of the protective shell, there are fixedly connected two inclined panels;

[0009] Two second sliding plates are slidably connected to the inner wall of the connecting frame. The side walls of the two second sliding plates are both fixedly connected to the side walls of the first spring return rods. At this time, the electric telescopic rod will start to push the first sliding plate downward. Since the blocking plates block the ventilation slots of the first sliding plate, the first sliding plate is in a closed state. When the first sliding plate moves downward, it compresses the gas inside the protective shell, enabling the hot air inside the protective shell to be quickly discharged. At the same time, above the first sliding plate, for example: Figure 1 As shown, it will also inhale the gas with a lower temperature in the external environment. As the first sliding plate continues to move, the inclined surface of the blocking plate will come into contact with the inclined surface of the inclined panel, causing the blocking plate to be squeezed and move in the direction of the electric telescopic rod. At the same time, it pushes the first spring return rod to move, enabling the first spring return rod to accumulate elastic force for return. When the blocking plate moves, it will open the ventilation slot, allowing the hot air and cold air in the protective shell to exchange.

[0010] Preferably, the heat dissipation mechanism further includes a push rod fixedly connected to the side wall of the second sliding plate. An I-shaped frame is rotatably connected to the inner wall of the connecting frame. Two push plates are slidably connected to the bottom of the connecting frame. The side walls of the two push plates are both fixedly connected to the side walls of the second spring return rods. At the same time, when the first spring return rod moves, it will also push the second sliding plate to move, compressing the gas inside the connecting frame. When the second sliding plate moves, it will also drive the push rod to move and come into contact with the I-shaped frame, pushing the I-shaped frame to rotate. When the I-shaped frame rotates, it will push the push plates to move, causing the two push plates to move away from each other, pushing the gas inside the protective shell. Since the first sliding plate compresses the space inside the protective shell, when the push plates push the gas in the protective shell, the hot air at the center of the protective shell will quickly move to both sides and exchange quickly with the cold air entering through the ventilation slot. By coordinating the gas pushed inside the protective shell and the gas ejected from the connecting frame, the exchange speed of the hot air and cold air inside the protective shell is accelerated, enabling the temperature inside the protective shell to be quickly reduced, preventing the heat dissipated by the lithium battery pack from being too high, thereby avoiding the collector being in a high-temperature environment and ensuring that the collector works in the best state and can accurately and timely reflect the remaining power in the battery.

[0011] Preferably, the cooling mechanism further includes two air delivery pipes penetrating and connected to the side walls of the fixed frame. The outer walls of the two air delivery pipes are both slidably connected to the inner wall of the protective shell. Two fixing rods are fixedly connected to the side walls of the two fixed frames respectively. Rotating plates are rotatably connected to the inner walls of the two fixed frames. By using the force generated by the movement of the push plate, when the push plate moves, it will also drive the second spring return rod to move, enabling the second spring return rod to accumulate resilience. At the same time, it drives the third sliding plate to slide within the fixed frame. Since the fixed frame is located inside the protective shell, the gas temperature inside the fixed frame is relatively high. When the third sliding plate moves, it will suck in the gas from the external environment through the air delivery pipe.

[0012] Preferably, the cooling mechanism further includes five arc-shaped springs fixedly connected to the bottom of the rotating plate. The side walls of the five arc-shaped springs are all fixedly connected to the bottom of the fixed frame. Two air intake holes are formed in the inner walls of the two third sliding plates respectively. Moving plates are fixedly connected to the side walls of the two third sliding plates respectively. Arc-shaped plates are fixedly connected to the tops of the two rotating plates. And the third sliding plate will squeeze the space inside the fixed frame, causing the hot air inside it to be squeezed. Since the molecular movement speed of the gas increases after the temperature rises, the air volume expands, generating an upward buoyancy force, which speeds up its flow rate. Also, due to the compression of the space inside the fixed frame, the hot air will exchange with the inhaled cold air through the air intake holes, enabling the cold air to enter the inside of the fixed frame and the hot air to be discharged through the air delivery pipe, reducing the temperature of the gas inside the fixed frame. As the third sliding plate continues to move, the fixing rod will block the air intake hole, making the inside of the fixed frame in a sealed state. Continuing to move the third sliding plate will squeeze the gas inside the fixed frame, causing the gas to generate high pressure until the moving plate contacts the arc-shaped plate, pushing the arc-shaped plate to move and making the rotating plate rotate, so that the high-pressure gas is sprayed towards the lithium battery pack and the collector, reducing their own temperatures, preventing the collector from overheating, and reducing the heat emitted by the lithium battery pack, achieving rapid heat exchange, thereby improving the cooling efficiency.

[0013] Preferably, the swinging mechanism further includes connecting plates arranged on the side walls of the fixed frame. Connecting rods are fixedly connected to the side walls of the two connecting plates respectively. The side walls of the two connecting rods are both fixedly connected to the side walls of the third sliding plate. Two connecting rods are rotatably connected to the side walls of the two connecting plates respectively;

[0014] The inner walls of the four connecting rods are all rotatably connected to the side wall of the extrusion plate. The first piston rods are slidably connected to the inner walls of the four first oil delivery pipes respectively. By using the force generated by the movement of the third sliding plate, when the third sliding plate moves, it will also drive the connecting rod to move towards the fixed sleeve, causing the connecting rod to rotate and pushing the extrusion plate to move. Since there is hydraulic oil I inside the fixed sleeve, the movement of the extrusion plate will push the hydraulic oil I to mix with the hydraulic oil II inside the first oil delivery pipe, pushing the first piston rod to descend.

[0015] Preferably, the swinging mechanism further includes an arc-shaped swinging plate disposed at the bottom of the fixed frame. Two connecting frames are fixedly connected to the bottom of each of the two fixed frames. Two rotating blocks are fixedly connected to the outer walls of the two arc-shaped swinging plates. The outer walls of the four rotating blocks are rotatably connected to the inner walls of the connecting frames. Spring blocks are fixedly connected to the bottoms of the four connecting frames. When contacting the rotating blocks, the rotating blocks will be pushed to rotate, squeezing the spring blocks to store their resilience. As the piston rod one continues to move, the rotation angle of the rotating block becomes larger, and the bottom of the piston rod one will separate from the rotating block. At this time, the resilience of the spring block will be released, causing the rotating block to swing, thereby driving the arc-shaped swinging plate to swing.

[0016] Preferably, the swinging mechanism further includes two sliding sleeves fixedly connected to the top of the first sliding plate. The outer walls of the two sliding sleeves are slidably connected to the inner wall of the protective shell. Two second oil pipes are connected through the bottoms of the two sliding sleeves. The side walls of the four second oil pipes are connected to the side wall of the fixed sleeve in a penetrating manner.

[0017] Among them, piston rods two are slidably connected to the inner walls of the four second oil pipes. A fourth sliding plate is slidably connected to the inner walls of the two sliding sleeves. Two spring plates are slidably connected to the inner walls of the two sliding sleeves. Hydraulic oil three is provided in the four second oil pipes. Using the force generated by the movement of the extrusion plate, when the extrusion plate moves to squeeze the hydraulic oil one in the fixed sleeve, the hydraulic oil one will also mix with the hydraulic oil three in the second oil pipe, pushing the piston rod two to rise. When the piston rod two rises, it will push the fourth sliding plate to move, squeezing the gas in the sliding sleeve. At this time, the squeezed gas will be blocked by the spring plate, so the gas will generate high pressure.

[0018] The present invention has the following beneficial effects:

[0019] (1) When the present invention is in use, the staff installs the collector and the lithium battery pack together. The collector collects and displays the power in the lithium battery pack, reminding the staff of the remaining power in the lithium battery pack. When the lithium battery pack discharges, the generated heat will be transferred to the heat-expandable bladder, causing the heat-expandable bladder to expand due to heat. When the heat generated by the lithium battery pack is relatively high, the expansion amplitude of the heat-expandable bladder will become larger and contact the start switch. At this time, the electric telescopic rod will be activated to push the first sliding plate downward. Since the blocking plate blocks the air vent groove of the first sliding plate, the first sliding plate is in a closed state. When the first sliding plate descends, it squeezes the gas in the protective shell, quickly exhausting the hot air in the protective shell. At the same time, above the first sliding plate, such as: Figure 1As shown, it will also inhale the gas with a lower temperature in the external environment. As the sliding plate 1 continues to move, the inclined surface of the baffle plate will come into contact with the inclined surface of the inclined panel, causing the baffle plate to be squeezed and move towards the electric telescopic rod. At the same time, it will push the spring return rod 1 to move, enabling the spring return rod 1 to accumulate the resilience. When the baffle plate moves, it will open the ventilation slot, allowing the hot air in the protective shell to exchange with the cold air. At the same time, when the spring return rod 1 moves, it will also push the sliding plate 2 to move, squeezing the gas in the connecting frame. When the sliding plate 2 moves, it will also drive the push rod to move and contact the I-shaped frame, pushing the I-shaped frame to rotate. When the I-shaped frame rotates, it will push the push plate to move, causing the two push plates to move away from each other, pushing the gas inside the protective shell. Since the sliding plate 1 squeezes the space inside the protective shell, when the push plate pushes the gas in the protective shell, the hot air at the center of the protective shell will quickly move to both sides and quickly exchange with the cold air entering through the ventilation slot. By coordinating the gas pushed inside the protective shell with the gas ejected from the connecting frame, the exchange speed of the hot air and cold air inside the protective shell is accelerated, enabling the temperature inside the protective shell to drop rapidly, preventing the heat emitted by the lithium battery pack from being too high, thus avoiding the collector being in a high-temperature environment and ensuring that the collector works in the best state and can accurately and timely reflect the remaining power in the battery.

[0020] (2) The present invention utilizes the force generated by the movement of the push plate. When the push plate moves, it will also drive the spring return rod 2 to move, enabling the spring return rod 2 to accumulate the resilience. At the same time, it will drive the sliding plate 3 to slide inside the fixed frame. Since the fixed frame is located inside the protective shell, the gas temperature inside the fixed frame is relatively high. When the sliding plate 3 moves, it will inhale the gas in the external environment through the air pipe, and the sliding plate 3 will squeeze the space inside the fixed frame, causing the hot air inside it to be squeezed. Since the molecular movement speed of the gas increases after the temperature rises, resulting in the expansion of the air volume, it will generate an upward buoyancy force, accelerating its flow speed. Also, due to the compression of the space inside the fixed frame, the hot air will exchange with the inhaled cold air through the air inlet hole, enabling the cold air to enter the inside of the fixed frame and the hot air to be discharged through the air pipe, reducing the temperature of the gas inside the fixed frame. As the sliding plate 3 continues to move, the fixed rod will block the air inlet hole, making the inside of the fixed frame in a sealed state. Continuing to move the sliding plate 3 will squeeze the gas inside the fixed frame, causing the gas to generate high pressure until the moving plate contacts the arc plate, pushing the arc plate to move and making the rotating plate rotate, so that the high-pressure gas is sprayed towards the lithium battery pack and the collector, reducing their own temperatures, being able to prevent the collector from overheating and reducing the heat emitted by the lithium battery pack, achieving rapid heat exchange, thereby improving the cooling efficiency and preventing the lithium battery pack and the collector from overheating.

[0021] (3) The present invention utilizes the force generated by the movement of the third sliding plate. When the third sliding plate moves, it will also drive the connecting rod to move towards the fixed sleeve, causing the connecting rod to rotate and pushing the extrusion plate to move. Since there is hydraulic oil I inside the fixed sleeve, the movement of the extrusion plate will push the hydraulic oil I to mix with the hydraulic oil II in the oil delivery pipe I, pushing the first piston rod to descend. When it contacts the rotating block, it will push the rotating block to rotate, squeezing the spring block and enabling it to accumulate resilience. As the first piston rod continues to move, the rotation angle of the rotating block becomes larger. Eventually, the bottom of the first piston rod will separate from the rotating block. At this time, the resilience of the spring block will be released, causing the rotating block to swing, thereby driving the arc-shaped swing plate to swing. When the arc-shaped swing plate swings, the high-pressure gas inside the fixed frame will also be ejected. Thus, the ejection direction of the gas can be controlled through the movement trajectory of the arc-shaped swing plate, making its range wider, so that the entire lithium battery pack and the collector can be cooled.

[0022] (4) The present invention utilizes the force generated by the movement of the extrusion plate. When the extrusion plate moves and squeezes the hydraulic oil I inside the fixed sleeve, the hydraulic oil I will also mix with the hydraulic oil III in the oil delivery pipe II, pushing the second piston rod to rise. When the second piston rod rises, it will push the fourth sliding plate to move, squeezing the gas inside the sliding sleeve. At this time, the squeezed gas will be blocked by the spring plate, so the gas will generate high pressure. As the fourth sliding plate rises, it will contact the spring plate and push the spring plate to move, enabling the spring plate to accumulate resilience. As the spring plate moves, the squeezed gas will be ejected. When exchanging hot air and cold air inside the protective shell, it can be quickly discharged, preventing the formation of water droplets when the hot and cold air exchange, which would increase the humidity inside the protective shell.

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Example 1, please refer to Figures 1 - 4 , the present invention is a lightweight high-energy power battery, including a heat dissipation mechanism 1. The heat dissipation mechanism 1 further includes a protective shell 101. A first sliding plate 102 is slidably connected to the inner wall of the protective shell 101. A connection frame 103 is fixedly connected to the bottom of the first sliding plate 102. Two ventilation grooves are opened in the inner wall of the first sliding plate 102;

[0037] Cooling mechanism 2, the cooling mechanism 2 includes two fixed frames 201 fixedly connected to the bottom of the connection frame 103. Sliding plates three 202 are slidably connected to the inner walls of the two fixed frames 201. Spring return rods two 203 are fixedly connected to the side walls of the two sliding plates three 202.

[0038] Swing mechanism 3, the swing mechanism 3 includes four fixed sleeves 301 fixedly connected to the bottom of the sliding plate one 102. Oil delivery pipes one 302 penetrate through the side walls of the four fixed sleeves 301. Extrusion plates 303 are slidably connected to the inner walls of the four fixed sleeves 301. Hydraulic oil one is provided in the inner walls of the four fixed sleeves 301. Hydraulic oil two is provided in the inner walls of the four oil delivery pipes one 302.

[0039] The heat dissipation mechanism 1 further includes an electric telescopic rod 104 fixedly connected to the top of the protective shell 101. The bottom output end of the electric telescopic rod 104 is fixedly connected to the top of the sliding plate one 102. A lithium battery pack 105 is fixedly connected to the bottom of the inner wall of the protective shell 101. A collector 106 is fixedly connected to the bottom of the inner wall of the protective shell 101.

[0040] Wherein, a heat expansion bag 107 is fixedly connected to the side wall of the lithium battery pack 105. A start switch 108 is fixedly connected to the inner wall of the protective shell 101. The staff installs the collector 106 and the lithium battery pack 105 together. The collector 106 collects and displays the power in the lithium battery pack 105, reminding the staff of the remaining power in the lithium battery pack 105. When the lithium battery pack 105 discharges, the generated heat will be transferred to the heat expansion bag 107, causing the heat expansion bag 107 to expand due to heat. When the heat generated by the lithium battery pack 105 is relatively high, the expansion amplitude of the heat expansion bag 107 will become larger and it will contact the start switch 108.

[0041] The heat dissipation mechanism 1 further includes two blocking plates 109 slidably connected to the bottom of the sliding plate one 102. Spring return rods one 110 are fixedly connected to the side walls of the two blocking plates 109. The outer walls of the two spring return rods one 110 are slidably connected to the bottom of the sliding plate one 102. Two inclined panels 111 are fixedly connected to the inner wall of the protective shell 101.

[0042] Two sliding plates two 112 are slidably connected to the inner wall of the connection frame 103. The side walls of the two sliding plates two 112 are fixedly connected to the side walls of the spring return rods one 110. At this time, the electric telescopic rod 104 will start, pushing the sliding plate one 102 downward. Since the blocking plate 109 blocks the ventilation slots of the sliding plate one 102, the sliding plate one 102 is in a closed state. When the sliding plate one 102 descends, it squeezes the gas in the protective shell 101, allowing the hot air in the protective shell 101 to be quickly discharged. At the same time, above the sliding plate one 102, such as: Figure 1As shown, it will also inhale the gas with a lower temperature in the external environment. As the sliding plate 102 continues to move, the inclined surface of the baffle plate 109 will come into contact with the inclined surface of the inclined panel 111, causing the baffle plate 109 to be squeezed and move in the direction of the electric telescopic rod 104. At the same time, it will push the first spring reset rod 110 to move, enabling the first spring reset rod 110 to accumulate resilience. When the baffle plate 109 moves, it will open the ventilation slot, allowing the hot air in the protective shell 101 to exchange with the cold air.

[0043] The heat dissipation mechanism 1 further includes a push rod 113 fixedly connected to the side wall of the second sliding plate 112. An I-shaped frame 114 is rotatably connected to the inner wall of the connection frame 103. Two push plates 115 are slidably connected to the bottom of the connection frame 103. The side walls of the two push plates 115 are fixedly connected to the side wall of the second spring reset rod 203. At the same time, when the first spring reset rod 110 moves, it will also push the second sliding plate 112 to move, squeezing the gas in the connection frame 103. When the second sliding plate 112 moves, it will drive the push rod 113 to move and come into contact with the I-shaped frame 114, pushing the I-shaped frame 114 to rotate. When the I-shaped frame 114 rotates, it will push the push plates 115 to move, causing the two push plates 115 to move away from each other, pushing the gas inside the protective shell 101. Since the first sliding plate 102 squeezes the space inside the protective shell 101, when the push plates 115 push the gas in the protective shell 101, the hot air at the center of the protective shell 101 will quickly move to both sides and exchange quickly with the cold air entering through the ventilation slot. By coordinating the gas pushed inside the protective shell 101 with the gas ejected from the connection frame 103, the exchange speed of the hot air and the cold air inside the protective shell 101 is accelerated, enabling the temperature inside the protective shell 101 to drop rapidly, preventing the heat emitted by the lithium battery pack 105 from being too high, thus avoiding the collector 106 being in a high-temperature environment and ensuring that the collector 106 operates in the best state and can accurately and timely reflect the remaining power in the battery.

[0044] Embodiment 2, please refer to Figures 5 - 9 , the present invention is a lightweight high-energy power battery. On the basis of Example 1, the cooling mechanism 2 further includes two air ducts 204 penetrating and connected to the side wall of the fixed frame 201. The outer walls of the two air ducts 204 are slidably connected to the inner wall of the protective shell 101. Two fixing rods 205 are fixedly connected to the side walls of the two fixed frames 201. Two rotating plates 206 are rotatably connected to the inner walls of the two fixed frames 201. Using the force generated by the movement of the push plates 115, when the push plates 115 move, they will also drive the second spring reset rod 203 to move, enabling the second spring reset rod 203 to accumulate resilience. At the same time, it will drive the third sliding plate 202 to slide inside the fixed frame 201. Since the fixed frame 201 is located inside the protective shell 101, the gas temperature inside the fixed frame 201 is relatively high. When the third sliding plate 202 moves, it will inhale the gas in the external environment through the air ducts 204.

[0045] The cooling mechanism 2 further includes five arc-shaped springs 207 fixedly connected to the bottom of the rotating plate 206. The side walls of the five arc-shaped springs 207 are fixedly connected to the bottom of the fixed frame 201. Two air inlet holes 208 are formed in the inner walls of the two sliding plates III 202. Moving plates 209 are fixedly connected to the side walls of the two sliding plates III 202. Arc-shaped plates 210 are fixedly connected to the tops of the two rotating plates 206. Moreover, the sliding plates III 202 will squeeze the space inside the fixed frame 201, causing the hot air inside it to be squeezed. Since the molecular movement speed of gas increases after the temperature rises, the air volume expands, generating an upward buoyancy force, which makes its flow speed increase. Also, due to the compression of the space inside the fixed frame 201, the hot air will exchange with the inhaled cold air through the air inlet holes 208, allowing the cold air to enter the inside of the fixed frame 201, and the hot air to be discharged through the air delivery pipe 204, reducing the temperature of the gas inside the fixed frame 201. As the sliding plates III 202 continue to move, the fixing rods 205 will block the air inlet holes 208, making the inside of the fixed frame 201 in a sealed state. Continuing to move the sliding plates III 202 will squeeze the gas inside the fixed frame 201, generating high pressure until the moving plates 209 contact the arc-shaped plates 210, pushing the arc-shaped plates 210 to move, causing the rotating plates 206 to rotate, and making the high-pressure gas spray towards the lithium battery pack 105 and the collector 106, reducing their own temperatures, preventing the collector 106 from overheating, and reducing the heat emitted by the lithium battery pack 105, achieving rapid heat exchange, thereby improving the cooling efficiency.

[0046] The swinging mechanism 3 further includes connecting plates 304 provided on the side walls of the fixed frame 201. Connecting rods 305 are fixedly connected to the side walls of the two connecting plates 304. The side walls of the two connecting rods 305 are fixedly connected to the side walls of the sliding plates III 202. Two connecting rods 306 are rotatably connected to the side walls of the two connecting plates 304;

[0047] The inner walls of the four connecting rods 306 are rotatably connected to the side walls of the pressing plate 303. The inner walls of the four oil delivery pipes I 302 are slidably connected with piston rods I 307. Using the force of the movement of the sliding plates III 202, when the sliding plates III 202 move, they will also drive the connecting rods 305 to move towards the fixed sleeve 301, causing the connecting rods 306 to rotate, pushing the pressing plate 303 to move. Since there is hydraulic oil I inside the fixed sleeve 301, the movement of the pressing plate 303 will push the hydraulic oil I to mix with the hydraulic oil II inside the oil delivery pipes I 302, pushing the piston rods I 307 to descend.

[0048] The swing mechanism 3 further includes an arc-shaped swing plate 309 disposed at the bottom of the fixed frame 201. Two connecting frames 308 are fixedly connected to the bottom of each of the two fixed frames 201. Two rotating blocks 310 are fixedly connected to the outer walls of the two arc-shaped swing plates 309. The outer walls of the four rotating blocks 310 are rotatably connected to the inner walls of the connecting frames 308. The bottoms of the four connecting frames 308 are fixedly connected with spring blocks 311. When contacting the rotating block 310, it will push the rotating block 310 to rotate, squeeze the spring block 311, and let it accumulate resilience. As the piston rod 307 continues to move, the rotation angle of the rotating block 310 becomes larger, and the bottom of the piston rod 307 will separate from the rotating block 310. At this time, the resilience of the spring block 311 will be released, causing the rotating block 310 to swing, thereby driving the arc-shaped swing plate 309 to swing.

[0049] The swing mechanism 3 further includes two sliding sleeves 312 fixedly connected to the top of the first sliding plate 102. The outer walls of the two sliding sleeves 312 are slidably connected to the inner wall of the protective shell 101. Two second oil pipes 313 are connected through the bottoms of the two sliding sleeves 312. The side walls of the four second oil pipes 313 are connected through the side walls of the fixed sleeve 301.

[0050] Among them, piston rods 314 are slidably connected to the inner walls of the four second oil pipes 313. A fourth sliding plate 315 is slidably connected to the inner walls of the two sliding sleeves 312. Two spring plates 316 are slidably connected to the inner walls of the two sliding sleeves 312. The four second oil pipes 313 are all provided with a third hydraulic oil. Using the force generated by the movement of the extrusion plate 303, when the extrusion plate 303 moves to squeeze the first hydraulic oil in the fixed sleeve 301, the first hydraulic oil will also mix with the third hydraulic oil in the second oil pipe 313, pushing the piston rod 314 to rise. When the piston rod 314 rises, it will push the fourth sliding plate 315 to move, squeezing the gas in the sliding sleeve 312. At this time, the squeezed gas will be blocked by the spring plate 316, so the gas will generate high pressure.

[0051] The number of the above components is not limited. Those skilled in the relevant art can freely set it according to actual needs, as long as the above components are installed at the corresponding connection positions of the components.

[0052] A specific application of this embodiment is as follows: When the present invention is in use, the staff installs the collector 106 and the lithium battery pack 105 together. The collector 106 collects and displays the power in the lithium battery pack 105, reminding the staff of the remaining power in the lithium battery pack 105. When the lithium battery pack 105 discharges, the generated heat will be transferred to the heat-expandable bladder 107, causing the heat-expandable bladder 107 to expand due to heat. When the heat generated by the lithium battery pack 105 is relatively high, the expansion amplitude of the heat-expandable bladder 107 will become larger and contact the start switch 108. At this time, the electric telescopic rod 104 will start, pushing the first sliding plate 102 downward. Since the baffle 109 blocks the ventilation slot of the first sliding plate 102, the first sliding plate 102 is in a sealed state. When the first sliding plate 102 descends, it squeezes the gas in the protective shell 101, quickly exhausting the hot air in the protective shell 101. At the same time, above the first sliding plate 102, such as: Figure 1 As shown, it will also inhale the gas with a lower temperature in the external environment. As the first sliding plate 102 continues to move, the inclined surface of the baffle 109 will contact the inclined surface of the inclined panel 111, causing the baffle 109 to be squeezed and move in the direction of the electric telescopic rod 104. At the same time, it pushes the first spring return rod 110 to move, enabling the first spring return rod 110 to accumulate the resilience. When the baffle 109 moves, it will open the ventilation slot, allowing the hot air and cold air in the protective shell 101 to exchange. At the same time, when the first spring return rod 110 moves, it will also push the second sliding plate 112 to move, squeezing the gas in the connecting frame 103. When the second sliding plate 112 moves, it will also drive the push rod 113 to move and contact the I-shaped frame 114, pushing the I-shaped frame 114 to rotate. When the I-shaped frame 114 rotates, it will push the push plate 115 to move, causing the two push plates 115 to move away from each other, pushing the gas inside the protective shell 101. Since the first sliding plate 102 squeezes the space inside the protective shell 101, when the push plate 115 pushes the gas in the protective shell 101, the hot air at the center of the protective shell 101 will quickly move to both sides and rapidly exchange with the cold air entering through the ventilation slot. By coordinating the gas pushed inside the protective shell 101 and the gas ejected from the connecting frame 103, the exchange speed of the hot air and cold air inside the protective shell 101 is accelerated, rapidly reducing the temperature inside the protective shell 101, preventing the heat emitted by the lithium battery pack 105 from being too high, thereby avoiding the collector 106 being in a high-temperature environment and ensuring that the collector 106 operates in the best state and can accurately and timely reflect the remaining power in the battery;

[0053] Among them, when the ventilation slot of the first sliding plate 102 is fully opened, the electric telescopic rod 104 will retract, driving the first sliding plate 102 to return to its original position, and then extend again to dissipate heat inside the protective shell 101. This process repeats until the protective shell 101 reaches an appropriate temperature. The expansion amplitude of the heat-expandable bladder 107 will become smaller and separate from the start switch 108, and the electric telescopic rod 104 will stop after returning to its original position;

[0054] Among them, compared with the fan blowing, when the fan blows, the air flow speed in the external environment is relatively fast, and more impurities and dust will be inhaled. The impurities and dust will adhere to the outer shell of the lithium battery pack 105. The dust may form a heat insulation layer between the outer shell of the lithium battery pack 105 and the environment, which will reduce the heat conduction, making it difficult for the lithium battery pack 105 to effectively dissipate the generated heat to the external environment. When using the first sliding plate 102 to squeeze the hot air in the protective shell 101 and inhale the gas in the external environment, the flow rate of the inhaled gas is slower, and less dust will be attracted. Moreover, part of the dust will fall on the top of the first sliding plate 102, preventing the dust from quickly adhering to the outer shell of the lithium battery pack 105. The fan blowing often has limitations. The heat dissipation speed is faster in the place directly blown by the fan, while the heat dissipation speed is slower in the place not blown, which may cause local overheating of the battery. The gas squeezed by the first sliding plate 102 in the protective shell 101 can evenly distribute the heat on the battery surface and reduce the risk of local overheating;

[0055] Secondly, when the pushing plate 115 moves, it will also drive the second spring reset rod 203 to move, so that the second spring reset rod 203 accumulates resilience. At the same time, it drives the third sliding plate 202 to slide in the fixed frame 201. Since the fixed frame 201 is located in the protective shell 101, the gas temperature inside the fixed frame 201 is relatively high. When the third sliding plate 202 moves, it will inhale the gas in the external environment through the air delivery pipe 204, and the third sliding plate 202 will squeeze the space inside the fixed frame 201, so that the hot air inside it is squeezed. Since the molecular movement speed of the gas increases after the temperature rises, resulting in the expansion of the air volume, it will generate an upward buoyancy force, making its flow speed faster. And because the space in the fixed frame 201 is compressed, the hot air will exchange with the inhaled cold air through the air inlet hole 208, allowing the cold air to enter the inside of the fixed frame 201 and the hot air to be discharged through the air delivery pipe 204, reducing the temperature of the gas inside the fixed frame 201. As the third sliding plate 202 continues to move, the fixed rod 205 will block the air inlet hole 208, making the inside of the fixed frame 201 in a sealed state. Continuing to move the third sliding plate 202 will squeeze the gas in the fixed frame 201, making the gas generate high pressure until the moving plate 209 contacts the arc-shaped plate 210, pushing the arc-shaped plate 210 to move, making the rotating plate 206 rotate, and spraying the high-pressure gas onto the lithium battery pack 105 and the collector 106, reducing its own temperature, preventing the collector 106 from overheating, and reducing the heat dissipated by the lithium battery pack 105, realizing rapid heat exchange, thereby improving the cooling efficiency and preventing the lithium battery pack 105 and the collector 106 from overheating;

[0056] Secondly, when the sliding plate three 202 moves, it will also drive the connecting rod 305 to move towards the fixed sleeve 301, causing the connecting rod 306 to rotate and pushing the extrusion plate 303 to move. Since there is hydraulic oil one inside the fixed sleeve 301, the movement of the extrusion plate 303 will push the hydraulic oil one to mix with the hydraulic oil two in the oil delivery pipe one 302, pushing the piston rod one 307 to descend. When it contacts the rotating block 310, it will push the rotating block 310 to rotate, squeezing the spring block 311 to store its resilience. As the piston rod one 307 continues to move, the rotation angle of the rotating block 310 becomes larger, and the bottom of the piston rod one 307 will separate from the rotating block 310. At this time, the resilience of the spring block 311 will be released, causing the rotating block 310 to swing, thereby driving the arc-shaped swing plate 309 to swing. When the arc-shaped swing plate 309 swings, the high-pressure gas inside the fixed frame 201 will also be ejected. Thus, the ejection direction of the gas can be controlled through the movement track of the arc-shaped swing plate 309, making its range wider, so that the entire lithium battery pack 105 and the collector 106 can be cooled;

[0057] Secondly, when the extrusion plate 303 moves to squeeze the hydraulic oil one inside the fixed sleeve 301, the hydraulic oil one will also mix with the hydraulic oil three in the oil delivery pipe two 313, pushing the piston rod two 314 to rise. When the piston rod two 314 rises, it will push the sliding plate four 315 to move, squeezing the gas inside the sliding sleeve 312. At this time, the squeezed gas will be blocked by the spring plate 316, so the gas will generate high pressure. As the sliding plate four 315 rises, it will contact the spring plate 316, pushing the spring plate 316 to move and enabling the spring plate 316 to store its resilience. As the spring plate 316 moves, the squeezed gas will be ejected, and when the hot air and cold air in the protective shell 101 are exchanged, it can be quickly discharged, preventing water droplets from condensing when the hot and cold air are exchanged, which would cause the humidity inside the protective shell 101 to increase.
