DETAILED DESCRIPTION

[0043] The present invention is further described below in conjunction with the accompanying drawings, and embodiments of the present invention are given in conjunction with the accompanying drawings.

[0044] Embodiment: A heat dissipation battery rack for lithium-ion batteries of electric buses.

[0045] Reference Figure 1-Figure 7 As shown, it includes a frame 1, a dual-axis motor 2, a wheel 3, a heat dissipation mechanism 5 and a blocking mechanism 6. Two dual-axis motors 2 are installed in the middle of the top left side of the frame 1. Wheels 3 are installed at the ends of the output shafts on both sides of the dual-axis motor 2. The right part of the frame 1 is also rotatably connected with wheels 3. There are two wheels 3 on the right side. A heat dissipation mechanism 5 is installed on the right side of the top of the frame 1. When the electric bus is running, the heat dissipation mechanism 5 can dissipate heat for the lithium-ion motor. A blocking mechanism 6 is installed on the heat dissipation mechanism 5. When the electric bus is placed for a long time, the blocking mechanism 6 can prevent mice from entering the heat dissipation mechanism 5 to cause damage.

[0046] The heat dissipation mechanism 5 includes a frame 51, a cover plate 52, an air inlet pipe 53 and an air outlet pipe 54. The frame 51 is installed on the right side of the top of the frame 1 by bolt connection. The operator can put the lithium-ion battery 4 into the frame 51 for use. The cover plate 52 is placed on the top of the frame 51. The middle right side of the frame 51 is connected to the air inlet pipe 53 by bolt connection. The right side of the outer bottom of the air inlet pipe 53 is fixedly connected to the right side of the top of the frame 1. The middle left side of the frame 51 is connected to the air outlet pipe 54. The tail end of the air outlet pipe 54 passes through the left part of the frame 1, and the air outlet pipe 54 is connected to the blocking mechanism 6.

[0047] The blocking mechanism 6 includes a return plate 61, a connecting rod 62 and a brush plate 63. The return plate 61 is installed between the left sides of the front and rear sides of the air outlet 54 by welding. Forty-one connecting rods 62 are evenly spaced and connected between the top and the bottom of the return plate 61. When the electric bus is placed for a long time, the connecting rod 62 can block the mouse. A brush plate 63 is slidably connected between the front and rear sides of the right side of the return plate 61. The brush plate 63 is in contact with the connecting rod 62. The brush plate 63 moves up and down to remove impurities on the connecting rod 62.

[0048] First, the operator puts an appropriate amount of lithium-ion batteries 4 into the heat dissipation mechanism 5, and then the electric bus can be used. When the electric bus travels to the right, wind can enter the heat dissipation mechanism 5, and the heat dissipation mechanism 5 dissipates heat to the lithium-ion battery 4 through wind. The hot wind after heat dissipation is continuously discharged from the heat dissipation mechanism 5, and the hot wind drives the blocking mechanism 6 to operate, and the blocking mechanism 6 can prevent mice from entering and damaging the lithium-ion battery 4. This is repeated, and the lithium-ion battery 4 can be continuously dissipated. When the electric bus stops traveling, the wind stops being discharged into the heat dissipation mechanism 5, the heat dissipation mechanism 5 stops dissipating heat to the lithium-ion battery 4 through wind, and the hot wind stops driving the blocking mechanism 6 to operate, and the blocking mechanism 6 also operates and resets. In this way, the lithium-ion battery 4 can be dissipated during use to prevent the lithium-ion battery 4 from being damaged due to excessive temperature.

[0049] First, the operator removes the cover plate 52 from the frame 51, and then puts an appropriate amount of lithium-ion batteries 4 into the frame 51. After the lithium-ion batteries 4 are placed, the cover plate 52 is put back on the frame 51. Then, when the electric bus is running, wind enters the air inlet pipe 53, and the wind in the air inlet pipe 53 is discharged into the frame 51. The wind dissipates heat for the lithium-ion battery 4. The wind after heat dissipation becomes hot wind, which is discharged into the air outlet pipe 54, and the hot wind in the air outlet pipe 54 is discharged. This is repeated, and the lithium-ion battery 4 can be continuously dissipated. When the electric bus stops running, the wind stops being discharged into the air inlet pipe 53, and the lithium-ion battery 4 is also stopped from being dissipated. In this way, the lithium-ion battery 4 can be prevented from being damaged due to excessive temperature.

[0050] When the hot air is discharged into the air outlet duct 54, the hot air drives the brush plate 63 to move upward to the maximum stroke. At the same time, the connecting rod 62 can prevent mice from entering the frame 51 through the air outlet duct 54 and damaging the lithium-ion battery 4. When the electric bus stops running, the wind stops being discharged into the air inlet duct 53, and no hot air is discharged into the air outlet duct 54. Due to the effect of gravity, the brush plate 63 moves downward to remove impurities on the connecting rod 62. In this way, it can be avoided that impurities remain and cause the hot air to be unable to be discharged.

[0051] Reference Figure 3 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.11 , Fig.12 , Fig.13 , Fig.14 , Fig.15 , Fig.16 , Fig.17 , Fig.18 , Fig.19 , Fig. 20 and Fig.21 As shown, it also includes a swing mechanism 7, which includes a fixed frame 71, a swing plate 72, a grid frame 73, an L-shaped plate 74, a return rack 75, a return fixed frame 76, a rotating shaft 77, a fan 78 and a missing gear 79. The fixed frame 71 is installed in the middle of the lower right side of the frame 51 by welding. The middle right side of the fixed frame 71 is connected to the left end of the air inlet pipe 53. Eleven swing plates 72 are rotatably connected between the top and the inner bottom of the fixed frame 71 at even intervals. When wind enters the frame 51, the swing plate 72 can swing back and forth to evenly discharge the wind into the frame 51. The grid frame 73 is slidably connected between the top and the inner bottom of the fixed frame 71, and the rod of the grid frame 73 passes through the eleven swing plates 72. When the grille frame 73 moves forward and backward, the grille frame 73 can drive the swing plate 72 to swing forward and backward. Three L-shaped plates 74 are evenly spaced and connected in the middle of the upper and lower sides of the right side surface of the grille frame 73. A circular rack 75 is installed between the inner ends of the six L-shaped plates 74 by welding. A circular fixing frame 76 is installed in the middle of the left top and the middle of the left bottom of the air inlet duct 53 by bolt connection. A rotating shaft 77 is rotatably connected between the middle of the left and right sides of the circular fixing frame 76. A missing gear 79 is fixed to the left end of the rotating shaft 77. The missing gear 79 is located in the circular rack 75. When the missing gear 79 rotates, the missing gear 79 can be meshed with the circular rack 75. A fan 78 is fixedly sleeved on the right side of the rotating shaft 77 along the circumferential direction.

[0052] The guide mechanism 8 also includes a hollow frame 81, an inclined hole plate 82, a U-shaped iron block 83, an electromagnet 84, a connecting rod 86, a guide rod 87 and a slider 88. A through hole 85 is opened on the left side of the bottom of the air inlet pipe 53. A guide rod 87 is installed on the upper left side of the through hole 85 by welding. The hollow frame 81 is rotatably mounted on the guide rod 87. When the hollow frame 81 is in an inclined state, the hollow frame 81 can guide rainwater. Fourteen uniformly spaced fixed portions are provided on the left side of the top of the hollow frame 81. An inclined hole plate 82 is provided, and a U-shaped iron block 83 is slidably connected between the lower left parts of the front and rear sides of the air inlet pipe 53. A connecting rod 86 is symmetrically installed on the bottom of the U-shaped iron block 83 through welding. A slider 88 is rotatably connected to the top of the connecting rod 86. The slider 88 is slidably connected to the bottom of the hollow frame 81. An electromagnet 84 is installed in the middle of the right side of the bottom of the frame 1. The electromagnet 84 corresponds to the U-shaped iron block 83. When the electromagnet 84 is energized, the electromagnet 84 can drive the U-shaped iron block 83 to move downward.

[0053] The drying mechanism 9 is also included, and the drying mechanism 9 includes a mesh frame 91, a U-shaped rack 92, a movable rod 93, a bellows 94, a rotating rod 95, a rotating gear 96 and an air outlet pipe 97. The lower left parts of the front and rear sides of the air outlet pipe 54 are rotatably connected with rotating rods 95, and the rotating rods 95 are located on the right side of the return plate 61. The mesh frame 91 is installed between the inner ends of the rotating rods 95 on the front and rear sides by welding. When the mesh frame 91 swings upward, the mesh frame 91 can guide part of the hot air into the bellows 94. The rear side of the bottom of the mesh frame 91 is connected with three bellows 94. The tail end of the bellows 94 passes through the frame 1 and the air inlet pipe 53 and the bottom of the hollow frame 81. The rear side is connected, the corrugated pipe 94 is connected with the hollow frame 81, the front side of the bottom of the hollow frame 81 is connected with an air outlet pipe 97, the tail end of the air outlet pipe 97 passes through the bottom left side of the air inlet pipe 53, and two movable rods 93 are installed on the bottom of the U-shaped iron block 83 by welding. The tail end of the movable rod 93 passes through the frame 1 and is fixedly connected with a U-shaped rack 92. The top two ends of the U-shaped rack 92 pass through the lower part of the air outlet pipe 54. The rotating rod 95 is fixedly sleeved with a rotating gear 96 near the position of the mesh frame 91, and the rotating gear 96 is meshed with the U-shaped rack 92. When the U-shaped rack 92 moves up and down, the U-shaped rack 92 can drive the rotating gear 96 to rotate alternately forward and reverse.

[0054] When wind enters the air inlet pipe 53 and contacts the fan 78, the wind drives the fan 78 to rotate forward, and the forward rotation of the fan 78 drives the rotating shaft 77 to rotate forward, and the forward rotation of the rotating shaft 77 drives the missing gear 79 to rotate forward, and when the missing gear 79 rotates forward and meshes with the lower part of the return rack 75, the missing gear 79 drives the return rack 75 to move forward, and the return rack 75 moves forward and drives the grid frame 73 to move forward through the L-shaped plate 74, and the grid frame 73 moves forward and drives the swing plate 72 to swing forward, and when the missing gear 79 continues to rotate forward and disengages from the lower part of the return rack 75, the return rack 75 moves forward. When the bar 75 stops moving forward, the swing plate 72 also stops moving forward, the missing gear 79 continues to rotate forward and meshes with the upper part of the return rack 75, the missing gear 79 drives the return rack 75 to move backward, the return rack 75 moves backward through the L-shaped plate 74 to drive the grid frame 73 to move backward, the grid frame 73 moves backward to drive the swing plate 72 to swing backward, and so on and so forth, the swing plate 72 can be continuously swung back and forth, the wind in the air inlet pipe 53 is discharged into the fixed frame 71, and the swing plate 72 drives the wind in the fixed frame 71 to swing back and forth and discharge into the frame 51. When the electric bus stops running, the wind stops being discharged into the air inlet pipe 53, the fan 78 stops driving the rotating shaft 77 to rotate forward, the rotating shaft 77 stops driving the missing gear 79 to rotate forward, the missing gear 79 stops driving the return rack 75 to move forward and backward, and the swing plate 72 also stops swinging back and forth. In this way, the wind can be evenly discharged into the frame 51 to dissipate heat for the lithium-ion battery 4.

[0055] When the electric bus starts to travel, the electromagnet 84 is started, and the electromagnet 84 starts to attract the U-shaped iron block 83 to move downward. The U-shaped iron block 83 moves downward and drives the connecting rod 86 to move downward. The connecting rod 86 moves downward and drives the right part of the hollow frame 81 to swing downward through the slider 88. The right part of the hollow frame 81 swings downward to make the left part swing upward. When the U-shaped iron block 83 moves downward and contacts the electromagnet 84, the U-shaped iron block 83 stops moving downward, the U-shaped iron block 83 stops driving the connecting rod 86 to move downward, and the connecting rod 86 stops driving the right part of the hollow frame 81 to swing downward through the slider 88. The left part of the hollow frame 81 also stops swinging upward. The hollow frame 81 is in an inclined state. The left part of the hollow frame 81 swings upward and drives the inclined hole plate 82 to swing upward. When rainwater falls into the air inlet pipe 53, the hollow frame 81 blocks the rainwater, and the rainwater flows out through the through hole 85. When the electric bus stops running, the electromagnet 84 can be turned off, and the electromagnet 84 stops sucking the U-shaped iron block 83. Due to the effect of gravity, the left part of the hollow frame 81 swings downward to reset, and the right part swings upward to reset. The right part of the hollow frame 81 swings upward to reset, and the U-shaped iron block 83 moves upward to reset through the slider 88. In this way, rainwater can be prevented from entering the frame 51 through the air inlet pipe 53 and contacting the lithium-ion battery 4 to cause a short circuit and affect the use.

[0056] When the electromagnet 84 is started, the U-shaped iron block 83 moves downward and also drives the movable rod 93 to move downward. The movable rod 93 moves downward and drives the U-shaped rack 92 to move downward. The U-shaped rack 92 moves downward and drives the rotating gear 96 to rotate forward. The rotating gear 96 rotates forward and drives the rotating rod 95 to rotate forward. The rotating rod 95 rotates forward and drives the screen frame 91 to rotate forward. Then, when the U-shaped iron block 83 contacts the electromagnet 84 and stops moving downward, the U-shaped iron block 83 stops driving the movable rod 93 to move downward, the U-shaped rack 92 stops driving the rotating gear 96 to rotate forward, and the screen frame 91 also stops rotating forward. The screen frame 91 is in an inclined state. When the hot air is discharged into the air outlet pipe 54, part of the hot air will be discharged into the screen frame 91, and the hot air in the screen frame 91 is discharged into the bellows 94. The hot air in the bellows 94 is discharged into the hollow frame 81. The hot air dries the hollow frame 81, and during the drying process, the hot air is discharged through the air outlet pipe 97. When the electromagnet 84 is turned off, the U-shaped iron block 83 moves upward to drive the movable rod 93 to move upward and reset, the movable rod 93 resets and drives the U-shaped rack 92 to move upward and reset, the U-shaped rack 92 moves upward and resets and drives the rotating gear 96 to reverse and reset, the rotating gear 96 reverses and resets and drives the screen frame 91 to reverse and reset through the rotating rod 95, and the hot air stops being discharged into the screen frame 91. In this way, a large amount of rainwater remaining on the hollow frame 81 can be prevented from flowing into the frame body 51 and contacting the lithium-ion battery 4.

[0057] Reference Figure 5 , Fig.10 , Fig.14 , Fig.15 , Fig. 22 , Fig.23 and Fig.24 As shown, a first air duct 10 and a second air duct 11 are also included. The first air duct 10 is installed between the middle parts of the front and rear side surfaces in the frame 51 by welding connection. When wind is discharged into the frame 51 to dissipate heat to the lithium-ion battery 4, the first air duct 10 can discharge the cold air at the lower right side into the upper left side to mix with the hot air. The second air duct 11 is installed between the middle parts of the front and rear side surfaces in the frame 51 by welding connection. When wind is discharged into the frame 51 to dissipate heat to the lithium-ion battery 4, the second air duct 11 can discharge the hot air at the upper right side into the lower left side to mix with the cold air. The first air duct 10 and the second air duct 11 are alternately arranged.

[0058] It also includes a limiting block 12 and a brush roller 13. The brush roller 13 is slidably connected between the holes of all the inclined hole plates 82. The brush roller 13 is in contact with the hollow frame 81. When the brush roller 13 moves, the brush roller 13 can remove the impurities remaining on the hollow frame 81. The limiting blocks 12 are installed on the front and rear ends of the brush roller 13 by welding. When the brush roller 13 moves, the limiting blocks 12 can limit the brush roller 13 to prevent it from detaching from the inclined hole plate 82.

[0059] When the wind is discharged into the frame 51 to dissipate heat for the lithium-ion battery 4, the wind first dissipates heat for the right lithium-ion battery 4. The wind in the heat dissipation will have hot wind and cold wind. The volume of the hot wind expands, which makes the density small, so the hot wind will be in the upper half of the frame 51. At the same time, the volume of the cold wind shrinks, which makes the density large, so the cold wind will be in the lower half of the frame 51. The cold wind continues to flow through the first air duct 10 and is discharged into the upper left half of the frame 51. The cold wind is mixed with the hot wind in the upper left part of the frame 51, so that the upper part of the left lithium-ion battery 4 will not always be hot wind, causing the temperature to be too high. The hot wind continues to flow through the second air duct 11 and is discharged into the lower left half of the frame 51. The hot wind is mixed with the cold wind in the lower left part of the frame 51, so that the lower part of the left lithium-ion battery 4 will not always be cold wind, causing the temperature to be too low. In this way, it can be avoided that the hot wind is always in the upper half and the cold wind is always in the lower half, affecting the heat dissipation.

[0060] When the left part of the hollow frame 81 swings upward, the inclined hole plate 82 also drives the brush roller 13 to swing upward, and then when the hollow frame 81 swings upward and is in an inclined state, due to the effect of gravity, the brush roller 13 moves downward to the maximum stroke, and the limit block 12 can prevent the brush roller 13 from being separated from the inclined hole plate 82. When the left part of the hollow frame 81 swings downward and drives the inclined hole plate 82 to swing downward and reset, because the hole of the inclined hole plate 82 is in an inclined state, due to the effect of gravity, the brush roller 13 moves to the left and resets to remove impurities on the hollow frame 81. In this way, a large amount of impurities remaining on the hollow frame 81 can be avoided to affect subsequent use.
