Description

Technical Field

[0001] The present invention relates to the technical field of lithium batteries, and in particular to an integral lithium battery structure that can replace a lead-acid battery. Background Art

[0002] Lead-acid battery is a storage battery whose electrodes are mainly made of lead and its oxides, and whose electrolyte is sulfuric acid solution. When the lead-acid battery is discharged, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead. However, the structure of lead-acid battery is relatively complex, and it is easy to leak and generate heat, and its safety performance is relatively low. At present, lithium batteries are basically used to replace lead-acid batteries. Lithium batteries are a type of battery that uses lithium metal or lithium alloy as positive / negative electrode materials and non-aqueous electrolyte solutions. Due to the very active chemical properties of lithium metal, the processing, storage, and use of lithium metal have very high environmental requirements. With the development of science and technology, lithium batteries have become mainstream.

[0003] For example, a lithium battery structure for an electric bicycle published with announcement number "CN117832727A" can install multiple U-shaped pieces on both sides of the shell by means of connecting pieces and spacers. As a result, the piston rod, piston head, spring and other components on the inner sides of the two ends of the U-shaped pieces can repeatedly push the piston rod to cause air flow to spray out from the opening to the heat dissipation groove with the help of buffering and squeezing effect during riding, so that the heat dissipated from the inside of the heat dissipation groove can be quickly guided out. In this way, the heat can be quickly dissipated with the help of the buffering process, which not only protects the shell but also protects the lithium battery body, achieving a dual purpose.

[0004] However, in actual use, the airflow is used to dissipate the heat of the lithium battery body through the piston rod, but the heat in the lithium battery body is difficult to dissipate, resulting in the inability to achieve effective heat dissipation. For this reason, we propose an overall lithium battery structure that can replace lead-acid batteries. Summary of the invention

[0005] The object of the present invention is to provide an integral lithium battery structure that can replace lead-acid batteries, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the present invention provides the following technical solution: an integral lithium battery structure that can replace a lead-acid battery, comprising a battery box and a lithium battery body, wherein a heat dissipation part for dissipating heat from the lithium battery body is provided inside the battery box, and a driven part for improving air circulation inside the battery box is provided inside the battery box; The heat dissipation unit comprises: An air intake cylinder is used to transport gas into the lithium battery body; A punching bag is used to discharge the gas inside the lithium battery body to dissipate heat; One-way mechanism: two groups of one-way mechanisms are provided, and the two groups of one-way mechanisms are symmetrically arranged in the air inlet and the air outlet.

[0007] Preferably, the air inlet cylinder is fixed on one side of the lithium battery body and is connected to the lithium battery body, the air outlet cylinder is fixed on the other side of the lithium battery body and is connected to the lithium battery body, the inner wall piston of the air inlet cylinder is connected to a piston plate, a push rod is fixed on the side of the piston plate away from the lithium battery body, the piston plate and the push rod are provided in two groups, one group of the piston plate and the push rod are arranged in the air inlet cylinder, and the other group of the piston plate and the push rod piston are connected in the air outlet cylinder, the two groups of the piston plates are provided with a one-way mechanism on the side away from the lithium battery body, a circular hole is opened on the side of the air inlet cylinder close to the lithium battery body, and the inner side of the circular hole is fixed A fixed plate is fixed, a baffle is provided on the inner side of the circular hole, a cross bar is fixed on the side of the baffle close to the fixed plate, the cross bar penetrates the fixed plate and is slidably connected with the fixed plate, a connecting spring is fixed on the side of the baffle close to the cross bar, and the end of the connecting spring away from the baffle is fixed to the fixed plate. When the piston plate moves to the right in the air intake cylinder, the gas in the air intake cylinder pushes the baffle to move to the right, and the baffle no longer blocks the circular hole, so that the gas can enter the lithium battery body. When the piston plate moves to the left in the air intake cylinder, under the action of the connecting spring, the baffle resets to the left, and the baffle blocks the circular hole, so that the gas cannot be discharged through the air intake cylinder.

[0008] Preferably, the one-way mechanism includes an air pipe, which passes through the piston plate and is fixed to the piston plate, a U-shaped tube is fixed on the top of the air pipe, both ends of the U-shaped tube are connected to the air pipe, the piston on the inner wall of the air pipe is connected to a moving block, and a resistance block is fixed on the inner wall of the air pipe, and the moving block can block the U-shaped tube. When the piston plate moves to the left in the air inlet cylinder, since the gas cannot enter the air inlet cylinder through the right side of the air inlet cylinder, at this time, the external gas can only be drawn through the air pipe. The external gas resists on the moving block, so that the moving block moves to the right, and the moving block can no longer block the U-shaped tube. The external gas can enter the air inlet cylinder through the air pipe and the U-shaped tube, thereby realizing gas replenishment. When the piston plate moves to the right in the air outlet cylinder, the air outlet cylinder draws the gas in the lithium battery body, and after entering the air inlet pipe, it resists on the moving block, pushing the moving block to move to the right, thereby realizing the discharge of the gas inside the lithium battery body, realizing gas circulation, and improving the heat dissipation of the lithium battery body.

[0009] Preferably, the battery box is provided with a control assembly, which includes a connecting frame, the connecting frame is slidably mounted on the side of the battery box, a return spring is fixed to the bottom of the connecting frame, the end of the return spring away from the connecting frame is fixed to the battery box, the bottom of the connecting frame is hinged with a support rod, the end of the support rod away from the connecting frame is hinged to the top of the moving rod, the moving rod passes through the side of the battery box and is slidably connected to the battery box, a vertical plate is fixed on the side of the moving rod close to the lithium battery body, and the end of the vertical plate away from the moving rod is fixed to the push rod. When in use, the connecting frame is connected to the shock absorber of the electric vehicle. When the electric vehicle is bumpy during riding, the shock absorber vibrates, thereby driving the connecting frame to move up and down, and the connecting frame can push or pull the moving rod to move the vertical plate left and right through the support rod, and the vertical plate can push the piston plate to move left and right through the push rod.

When the needle rotates, the thrust generated by the rotation of gear one causes the slide bar to move with the small gear along the fixed frame to the side close to gear three. When the small gear cannot move, it meshes with gear one and rotates counterclockwise. The small gear meshes with gear three and drives gear three to rotate clockwise. Gear three drives the fan to rotate clockwise through the connecting rod, drawing external gas into the lithium battery body. When gear one rotates counterclockwise, gear one drives the small gear to move to the side of gear two. When the small gear cannot move, the small gear rotates clockwise, the small gear drives gear two to rotate counterclockwise, and gear two drives gear three to rotate clockwise. Therefore, when the vertical plate moves left and right, the fan can rotate in one direction to achieve stable air intake or exhaust.

[0011] Preferably, two groups of the driven parts are provided, and the two groups of the driven parts are symmetrically arranged in the battery box. One group of driven parts is used to draw external gas into the battery box, and the other group of driven parts is used to discharge the gas inside the battery box, thereby accelerating the gas flow and further improving the heat dissipation effect.

[0012] Preferably, a hole for the fan to pass through is opened on the surface of the battery box.

[0013] Compared with the prior art, the present invention provides an integral lithium battery structure that can replace lead-acid batteries, and has the following beneficial effects: 1. The overall lithium battery structure that can replace the lead-acid battery has a heat dissipation part and a control component. When bumps occur during riding, the shock absorber vibrates, thereby driving the connecting frame to move up and down.

[0019] The air inlet cylinder 31 is fixed on one side of the lithium battery body 2 and is connected to the lithium battery body 2, and the air outlet cylinder 32 is fixed on the other side of the lithium battery body 2 and is connected to the lithium battery body 2. The inner wall piston of the air inlet cylinder 31 is connected to a piston plate 35, and a push rod 310 is fixed on the side of the piston plate 35 away from the lithium battery body 2. There are two groups of piston plates 35 and push rods 310. One group of piston plates 35 and push rods 310 are arranged in the air inlet cylinder 31, and the other group of piston plates 35 and push rods 310 are connected to the air outlet cylinder 32. A one-way mechanism 33 is arranged on the side away from the lithium battery body 2 of the two groups of piston plates 35. A circular hole 36 is opened on the side of the air inlet cylinder 31 close to the lithium battery body 2, and a fixing plate 37 is fixed on the inner side of the circular hole 36. 6 is provided with a baffle plate 38 on the inner side, and a cross bar 39 is fixed on the side of the baffle plate 38 close to the fixed plate 37, and the cross bar 39 penetrates the fixed plate 37 and is slidably connected with the fixed plate 37. A connecting spring 34 is fixed on the side of the baffle plate 38 close to the cross bar 39, and one end of the connecting spring 34 away from the baffle plate 38 is fixed to the fixed plate 37. When the piston plate 35 moves to the right in the air intake cylinder 31, the gas in the air intake cylinder 31 pushes the baffle plate 38 to move to the right, and the baffle plate 38 no longer blocks the circular hole 36, so that the gas can enter the lithium battery body 2. When the piston plate 35 moves to the left in the air intake cylinder 31, under the action of the connecting spring 34, the baffle plate 38 resets to the left, and the baffle plate 38 blocks the circular hole 36, so that the gas cannot be discharged through the air intake cylinder 31.

[0020] The one-way mechanism 33 includes an air pipe 331, which passes through the piston plate 35 and is fixed to the piston plate 35. A U-shaped pipe 332 is fixed to the top of the air pipe 331. Both ends of the U-shaped pipe 332 are connected to the air pipe 331. A moving block 333 is connected to the piston on the inner wall of the air pipe 331. An abutment block 334 is fixed on the inner wall of the air pipe 331. The moving block 333 can block the U-shaped pipe 332. When the piston plate 35 moves to the left in the air intake cylinder 31, since the gas cannot enter the air intake cylinder 31 through the right side of the air intake cylinder 31, the external gas can only be pumped through the air pipe 331. The external gas hits the moving block 333, causing the moving block 333 to move to the right. The moving block 333 can no longer block the U-shaped tube 332. The external gas can enter the air inlet cylinder 31 through the air pipe 331 and the U-shaped tube 332, thereby achieving gas replenishment. When the piston plate 35 moves to the right in the air outlet cylinder 32, the air outlet cylinder 32 draws the gas in the lithium battery body 2, which enters the air inlet pipe 331 and hits the moving block 333, pushing the moving block 333 to move to the right, thereby achieving the discharge of the gas inside the lithium battery body 2, achieving gas circulation, and improving the heat dissipation of the lithium battery body 2.

[0021] The battery box 1 is provided with a control assembly 5, which includes a connecting frame 51, which is slidably mounted on the side of the battery box 1, and a return spring 52 is fixed to the bottom of the connecting frame 51, and the end of the return spring 52 away from the connecting frame 51 is fixed to the battery box 1, and a support rod 53 is hinged at the bottom of the connecting frame 51, and the end of the support rod 53 away from the connecting frame 51 is hinged at the top of a moving rod 54, and the moving rod 54 passes through the side of the battery box 1 and is slidably connected to the battery box 1, and a vertical plate 55 is fixed on the side of the moving rod 54 close to the lithium battery body 2, and the end of the vertical plate 55 away from the moving rod 54 is fixed to the push rod 310. When in use, the connecting frame 51 is connected to the shock absorber of the electric vehicle. When the electric vehicle is bumpy during riding, the shock absorber vibrates, thereby driving the connecting frame 51 to move up and down, and the connecting frame 51 can push or pull the moving rod 54 through the support rod 53 to move the vertical plate 55 left and right, and the vertical plate 55 can push the piston plate 35 left and right through the push rod 310.

[0022] The driven part 4 includes a rack 41, which is fixed to a side of the vertical plate 55 away from the moving rod 54, a gear 1 42 is meshed on the top of the rack 41, and the gear 1 42 is rotatably mounted on the inner wall of the battery box 1, the gear 1 42 is meshed with a pinion 43, and the pinion 43 is rotatably mounted on the surface of the slide bar 44, and the slide bar 44 is slidably mounted on the inner side of the fixing frame 45, and the fixing frame 45 is fixed on the inner wall of the battery box 1, and a gear 2 46 and a gear 3 47 are rotatably mounted on the inner wall of the battery box 1, the gear 2 46 is meshed with the gear 3 47, and a connecting rod 48 is fixed on the surface of the gear 3 47, and a fan 49 is fixed on the end of the connecting rod 48 away from the gear 3 47. When the vertical plate 55 moves left and right, the rack 41 can be driven to move left and right, and the rack 41 controls the gear 1 42 to rotate forward and reverse. When the gear 1 42 rotates clockwise, the gear 1 46 rotates clockwise. The thrust generated by the rotation causes the slide bar 44 to move with the pinion 43 along the fixing frame 45 toward the side close to the gear three 47. When the pinion 43 cannot move, it meshes with the gear one 42 to rotate counterclockwise. The pinion 43 meshes with the gear three 47 to drive the gear three 47 to rotate clockwise. The gear three 47 drives the fan 49 to rotate clockwise through the connecting rod 48, and draws external air into the lithium battery body 2. When the gear one 42 rotates counterclockwise, the gear one 42 drives the pinion 43 to move toward the side of the gear two 46. When the pinion 43 cannot move, the pinion 43 rotates clockwise, the pinion 43 drives the gear two 46 to rotate counterclockwise, and the gear two 46 drives the gear three 47 to rotate clockwise. Therefore, when the vertical plate 55 moves left and right, the fan 49 can be rotated in one direction to achieve stable air intake or exhaust.

[0023] Two groups of follower parts 4 are provided, and the two groups of follower parts 4 are symmetrically arranged in the battery box 1. One group of follower parts 4 is used to draw external gas into the battery box 1, and the other group of follower parts 4 is used to discharge the internal gas of the battery box 1, so as to accelerate the gas flow and further improve the heat dissipation effect. The surface of the battery box 1 is provided with holes for the fan 49 to pass through.

[0024] Based on the above embodiment, when in use, the connecting frame 51 is connected to the shock absorber of the electric vehicle. When the electric vehicle is bumpy during riding, the shock absorber vibrates, thereby driving the connecting frame 51 to move up and down. The connecting frame 51 can push or pull the moving rod 54 through the support rod 53 to move the vertical plate 55 left and right. The vertical plate 55 can push the piston plate 35 to move left and right through the push rod 310. When the piston plate 35 moves to the left in the air intake cylinder 31, since the gas cannot enter the air intake cylinder 31 through the right side of the air intake cylinder 31, the external gas can only be pumped through the air pipe 331. The external gas The body abuts against the moving block 333, causing the moving block 333 to move to the right. The moving block 333 can no longer block the U-shaped tube 332, and the external gas can enter the air inlet cylinder 31 through the air pipe 331 and the U-shaped tube 332, thereby realizing gas replenishment. When the piston plate 35 moves to the right in the air outlet cylinder 32, the air outlet cylinder 32 draws the gas in the lithium battery body 2, and after entering the air inlet pipe 331, it abuts against the moving block 333, pushing the moving block 333 to move to the right, thereby realizing the discharge of the gas inside the lithium battery body 2, realizing gas circulation, and improving the heat dissipation of the lithium battery body 2.

[0025] When the vertical plate 55 moves left and right, it can drive the rack 41 to move left and right, and the rack 41 controls the gear 1 42 to rotate forward and reverse. When the gear 1 42 rotates clockwise, the thrust generated by the rotation of the gear 1 42 causes the slide bar 44 to move with the pinion 43 along the fixed frame 45 to the side close to the gear 3 47. When the pinion 43 cannot move, it meshes with the gear 1 42 and rotates counterclockwise. The pinion 43 meshes with the gear 3 47 and drives the gear 3 47 to rotate clockwise. The gear 3 47 drives the fan 49 to rotate clockwise through the connecting rod 48, and draws external air into the lithium battery body 2. When the gear 1 42 rotates counterclockwise, the gear 1 42 drives the pinion 43 to move to one side of the gear 2 46. When the pinion 43 cannot move, the pinion 43 rotates clockwise, and the pinion 43 drives the gear 2 46 to rotate counterclockwise. The gear 2 46 drives the gear 3 47 to rotate clockwise. Therefore, when the vertical plate 55 moves left and right, the fan 49 can be rotated in one direction to achieve stable air intake or exhaust.

[0026] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
