Description
Technical Field

[0002] As one of the energy sources for RVs, RV lithium batteries provide a lot of convenience for people to go out and play. Generally, RV trips are long, so the usage time of RV lithium batteries becomes very long, which will have certain impacts and safety hazards on RV lithium batteries in the long run. The capacity of common lithium batteries is not very large, and they will directly indicate that they are prohibited from being exposed to the sun or placed in unventilated places, because lithium batteries will continue to generate heat during the discharge process, especially the parking air-conditioning commonly used in RVs consumes power. If the duration is too long, it will cause the lithium battery to discharge at a high rate and exceed the normal operating temperature, thereby bringing dangerous factors. In addition, when the lithium battery is thermally out of control, external and internal factors will further cause the heat in the battery to accumulate or continue to not dissipate, and a violent lithium explosion reaction will occur after reaching the critical point of the battery. Based on the purpose of emergency treatment of combustion or explosion of RV lithium batteries, the present invention provides a lithium-ion battery for RVs with a safe power transmission mechanism and a method of using the same.

[0013] A method for using a lithium-ion battery for a motorhome with a safe power transmission mechanism comprises the following steps:

The air is injected into each unit square tube, carrying away the heat emitted by the battery, and then discharged through the exhaust holes on the unit square tube. The battery is continuously ventilated and cooled;
[0015] Step 2: When a single battery generates too much heat unexpectedly, the high temperature is detected by the temperature measuring rod group on the top, which then triggers the unit tool on one side to work. The unit tool drives the two half door panels to flip and separate, and the top channel of the unit square tube opens. At the same time, any unit tool work will further trigger the power storage tool to work through the L-shaped control rod. The power storage tool releases power to supply the pusher, and the pusher pushes the firefighting powder stored in the tank into the unit square tube with the channel opened;
[0016] Step 3: If the battery in the unit square tube has already produced an open flame, the fire-fighting powder injection process will directly extinguish the open flame and block the smoke and dust from being discharged. If no open flame is produced, the area around the battery will be submerged by the filled fire-fighting powder to prevent the occurrence of open flames in advance.
[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] 1. The present invention uses a tank body for storing fire-fighting powder at the top of a row of unit square tubes, which can effectively reduce the overall space occupied by lithium batteries. The battery of the present invention is more suitable for an environment such as a motorhome that has requirements on space volume. If a battery in any unit square tube accidentally overheats or burns, it will trigger the fire-fighting powder to be completely injected into the unit square tube with an overheated internal environment, thereby extinguishing the open fire on the battery, isolating oxygen and covering the smoke, and preventing people in the motorhome from inhaling smoke and being poisoned.
[0019] 2. The present invention cooperates with the unit tool, L-shaped control rod and power storage tool. Any overheating of the battery will automatically trigger the corresponding unit tool to work, and any unit tool work will trigger the power storage tool through the L-shaped control rod. The power storage tool releases power to supply the pushing tool, and the pushing tool quickly completes the fire powder pushing work, and the whole process is automatically adjusted and controlled.

[0044] A method for using a lithium-ion battery for a motorhome with a safe power transmission mechanism comprises the following steps:
[0045] Step 1: Connect the multi-channel tube to all the air inlet tubes 9, and after the air supply end of the multi-channel tube is led to the outside of the battery box 1, it is connected to the air blowing mechanism, and air is injected into each unit square tube 5, carrying away the heat emitted by the battery 6, and then discharged through the exhaust holes on the unit square tube 5, and the battery 6 is continuously ventilated and cooled;
[0046] Step 2: When a single battery 6 generates too much heat unexpectedly, the high temperature is detected by the temperature measuring rod group 7 on the top, and then the unit tool 8 on one side is triggered to work, and the unit tool 8 drives the two half door panels 14 to flip and separate, and the top channel of the unit square tube 5 is opened. At the same time, any unit tool 8 will further trigger the power storage tool 11 to work through the L-shaped control rod 10, and the power storage tool 11 releases power to supply the pusher 12, and the pusher 12 pushes the firefighting powder stored in the trough 13 into the unit square tube 5 with the opened channel;
[0047] Step 3: If the battery 6 in the unit square tube 5 has already generated an open flame, the fire-fighting powder injection process will directly extinguish the open flame and block the smoke from being discharged. If no open flame is generated, the area around the battery 6 will be submerged by the filled fire-fighting powder to prevent the generation of open flames in advance.
[0048] If a single battery 6 fails during lithium battery operation, the battery 6 that is still charging and discharging will dissipate a lot of heat, and the temperature in the unit square tube 5 storing the battery 6 will rise. Normal ventilation cannot meet the heat dissipation needs, and the deformation rod 22 will expand and deform due to heat. The deformation rod 22 will extend and push the L-shaped vertical plate 26. After the L-shaped vertical plate 26 is translated, it will no longer block the L-shaped horizontal plate 24. In this way, the compression spring 28 pushes the L-shaped horizontal plate 24 to move. The L-shaped horizontal plate 24 moves and drives the worm 19 to rotate, thereby driving the concave folding control column 16 to rise. The rise of the concave folding control column 16 drives Figure 6 The two door shafts 15 in the middle rotate synchronously, thereby causing the two half door panels 14 to rotate 90 degrees. Figure 6 The two half door panels 14 in the middle will become parallel and vertical. The two half door panels 14 originally closed and blocked the top opening of the unit square tube 5. After opening, the fire-fighting powder in the trough body 13 can fall into the unit square tube 5, thereby extinguishing the open fire on the battery 6 and covering the smoke. The fire-fighting powder here can be fire-fighting sand, or other non-flammable powders in the prior art.
[0049] When the concave control column 16 rises, it also drives the L-shaped control rod 10 to rise. After one end of the L-shaped control rod 10 rises, it no longer blocks the positioning disk 29, so that the positioning disk 29 can rotate, and the clockwork 33 quickly releases its force to drive the secondary shaft 34 to rotate, and then drives the double control shaft 30 to rotate through the disk gear 32. The double control shaft 30 transmits two pressure-breaking devices 39, and then drives the two screw rods 35 to rotate. Here, the rotation directions of the two screw rods 35 are opposite. The rotation of the screw rod 35 causes the L-shaped short rack 36 to translate. The screw rod 35 also has a direction guiding function for the flat plate 37. The L-shaped short rack 36 translates and drives the flat plate 37. The two flat plates 37 approach each other. During the approaching process, they encounter the upper edge of the half door panel 14 that is rotated to the upright state. The half door panel 14 The upper edge will intercept the positioning plate 37. If the unit square tube 5 that opens the channel is not located at the center of the two plates 37, one plate 37 will be intercepted in advance by the half door panel 14, and the other plate 37 will not be intercepted and continues to move horizontally. This is because the double-control shaft 30 transmits the two screw rods 35 through the two pressure-breaking devices 39. If one screw rod 35 no longer rotates, it will not affect the other end screw rod 35 being driven by the double-control shaft 30. The rotating screw rod 35 is driven by the pressure-breaking device 39. The internal transmission of the pressure-breaking device 39 connected to the screw rod 35 that cannot rotate is broken, that is, the S-shaped spring piece 41 is misaligned with the stationary screw rod 35, and the pressure-breaking device 39 plays the function of over-pressure interruption transmission.
