Description

Technical Field

[0001] The present invention relates to the technical field of battery packs, and in particular to a battery pack with a protective structure on an electric scooter. Background Art

[0002] The electric skateboard is a means of transportation based on the traditional human-powered skateboard with an electric power kit. The control method of the electric scooter is the same as that of the traditional electric bicycle, and it is easy for the driver to learn. It is equipped with a detachable and foldable seat. It has a simpler structure, smaller wheels, and is lighter and simpler than the traditional electric bicycle. It can save a lot of social resources. Its main source of electricity is lithium battery packs.

[0003] Most of the existing battery packs do not have a protective structure, which makes the battery pack easily damaged or displaced after a collision, causing the battery pack to be unable to be used normally. At the same time, the existing battery packs do not have a wireless charging function, which requires users to disassemble the battery pack for power replenishment, resulting in low convenience in using the battery pack. Furthermore, the existing battery packs do not have a good heat dissipation function, which makes the battery pack easily generate high temperature during long-term operation, thereby affecting the internal electronic components. Therefore, there is an urgent need for a battery pack with a protective structure on an electric scooter to solve the existing problems. Summary of the invention

[0004] The purpose of the present invention is to provide a battery pack with a protective structure for an electric scooter in order to solve the above-mentioned problem.

[0005] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0007] By adopting the above technical scheme, the design of the energy absorption box 1, the energy absorption box 2 and the shock-absorbing pad can enable the battery pack to have a protective structure, so that the battery pack can greatly reduce the impact force after a collision, thereby avoiding damage or displacement of the battery pack, and ensuring the normal use of the battery pack. The design of the bottom plate and the wireless charging receiving end can enable the battery pack to have a wireless charging function, so that the user can replenish electricity without disassembling the battery pack, thereby improving the convenience of using the battery pack. The design of the thermal conductive sheet 1, the thermal conductive sheet 2, the heat sink 1 and the heat sink 2 can enable the battery pack to have good heat dissipation capabilities. When the battery pack generates high temperature during long-term operation, the internal heat can be effectively guided and dissipated, thereby ensuring the normal operation of internal electronic components.

[0008] Furthermore, the bottom plate is bonded to the rubber pad, and the hollow groove is formed on the rubber pad.

[0009] By adopting the above technical solution, the connection between the battery pack and other components can be made tighter.

[0010] Furthermore, the base plate is connected to the fixing bolts via threads.

[0011] By adopting the above technical solution, the battery pack can be fixed more firmly.

[0012] Furthermore, the bottom plate is welded to the containing box, the containing box is connected to the first energy absorbing box via screws, and the containing box is connected to the second energy absorbing box via screws.

[0013] By adopting the above technical solution, the battery pack can be provided with a protective structure, so that the impact force of the battery pack can be greatly reduced after a collision, thereby avoiding damage or displacement of the battery pack and ensuring the normal use of the battery pack.

[0014] Furthermore, the first heat dissipation window and the second heat dissipation window are both formed on the containing box.

[0016] Furthermore, the containing box is bonded to the shock absorbing pad.

[0017] By adopting the above technical solution, the anti-vibration capability of the battery pack can be increased.

[0018] Furthermore, the containing box is connected to the partition plate via a card slot, the containing box is connected to the battery block via a card slot, and the battery block is electrically connected to the connecting wire.

[0019] By adopting the above technical solution, the circuit connection of the battery pack can be made more stable.

[0020] Furthermore, the battery block is connected to the first heat conductive sheet and the second heat conductive sheet via a slot, the first heat sink is formed on the first heat conductive sheet, and the second heat sink is formed on the second heat conductive sheet.

[0021] By adopting the above technical solution, when the battery pack generates high temperature during long-term operation, the internal heat can be effectively guided and dissipated, thereby ensuring the normal operation of the internal electronic components.

[0022] Furthermore, the battery block is connected to the tower spring via a slot, and the battery block is connected to the shock absorbing spring via a slot.

[0023] By adopting the above technical solution, the battery pack can be effectively prevented from being displaced when a minor collision occurs.

[0024] Furthermore, the base plate is connected to the wireless charging receiving end via a card slot.

[0025] By adopting the above technical solution, the battery pack can have a wireless charging function, so that the user can replenish power without disassembling the battery pack, thereby improving the convenience of using the battery pack.

[0026] The specific working principle is: when in use, the staff can use the fixing bolts to firmly connect the battery pack with other components, and the rubber pad can make the connection tighter. When the battery pack is subjected to a strong impact force, the energy absorption box 1 and the energy absorption box 2 can greatly reduce the impact force, thereby avoiding damage or displacement of the battery pack, and ensuring the normal use of the battery pack. When the battery pack is subjected to a weaker impact force, the shock-absorbing pad, the conical spring and the shock-absorbing spring can effectively prevent the battery pack from being displaced, and ensure the stable circuit connection between the battery packs. When the battery pack generates high temperature during long-term operation, the heat conductive sheet 1 and the heat conductive sheet 2 can guide the heat generated by the battery block and dissipate it to the outside through the heat sink 1 and the heat sink 2, so as to ensure the normal operation of the internal electronic components. When charging is needed, the battery pack only needs to be placed on the wireless charging output end, and the wireless charging receiving end will receive the electromagnetic waves and convert them into electrical energy for replenishment.

[0027] The beneficial effects of the present invention are:

[0028] 1. By setting the energy absorption box 1, energy absorption box 2 and shock-absorbing pad, the battery pack can have a protective structure, which can greatly reduce the impact force of the battery pack after a collision, thereby avoiding damage or displacement of the battery pack and ensuring the normal use of the battery pack;

[0029] 2. By setting up the bottom plate and the design of the wireless charging receiving end, the battery pack can have a wireless charging function, so that the user can replenish the power without removing the battery pack, thereby improving the convenience of using the battery pack;

[0030] 3. By arranging the design of heat conductive sheet 1, heat conductive sheet 2, heat sink 1 and heat sink 2, the battery pack can have good heat dissipation ability. When the battery pack generates high temperature due to long-term operation, the internal heat can be effectively guided and dissipated, thereby ensuring the normal operation of internal electronic components.
