The continuous pressure on the storage unit by the deformed battery pack shell area can easily lead to further failure of the storage unit, thereby affecting the safety of electricity use. Summary of the invention

[0006] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that when the battery pack of the existing product is subjected to a strong impact, it is difficult to adjust the operation of the storage unit therein according to the deformation state of the battery pack shell after the impact.

[0028] The following describes two implementation modes of the present application in detail with reference to the accompanying drawings.

[0029] The first implementation method:

[0030] Figure 1-7A storage battery with an anti-impact protection structure is shown, comprising an outer shell 1, a plurality of evenly distributed power storage units 2 are installed in the outer shell 1, a partition layer 11 fixedly connected to the outer shell 1 is arranged between two adjacent power storage units 2, an anti-impact layer 3 is clamped on the inner wall of the outer shell 1, and the anti-impact layer 3 surrounds the plurality of power storage units 2, a plurality of evenly distributed mounting holes are opened on the anti-impact layer 3, and a strengthening buffer column 4 is detachably installed in the mounting hole;

[0031] The strengthening buffer column 4 includes an elastic sealing tube 401, the upper and lower ends of the elastic sealing tube 401 are respectively connected to a laser receiver 402 and a laser transmitter 403, and a buffer block 404 is filled in the elastic sealing tube 401, and a through hole is opened in the middle of the buffer block 404;

[0032] A power connection board 5 matching the outer shell 1 is connected between the multiple power storage units 2, and a distribution board electrically connected to the multiple power storage units 2 is installed on the power connection board 5. A terminal is installed on the top of the reinforced buffer column 4, and the reinforced buffer column 4 is electrically connected to the distribution board through the terminal, and a signal line is connected between the terminal and the distribution board; a battery management module and a monitoring module are arranged in the distribution board, and a vibration sensor connected to the signal of the monitoring module is installed in the outer shell 1; a sealing cover 6 covering the power connection board 5 is clamped on the outer shell 1, and a charging interface and a power transmission interface are arranged on the sealing cover 6.

[0033] The materials used to manufacture the impact-resistant layer 3 and the barrier layer 11 include silicone rubber, polyurethane, elastic foam material and elastomeric plastic.

[0034] An elastic wire is embedded in the buffer block 404 , and the laser receiver 402 is connected to the buffer block 404 through the elastic wire. The buffer block 404 is a porous air-permeable structure, and the manufacturing materials of the buffer block 404 include: buffer sponge and porous rubber.

[0035] It also includes an emergency protection system, which includes a processor and an alarm module installed in the distribution board. The alarm module, the monitoring module and the battery management module are all connected to the processor signal. The battery management module is used to associate multiple reinforced buffer columns 4 with the storage unit 2 and control the power on and off of the storage unit 2; specifically, each storage unit 2 is associated with a reinforced buffer column 4 at a close distance to it. When any reinforced buffer column 4 associated with the storage unit 2 detects deformation, the storage unit 2 is controlled to be powered off.

[0036] The monitoring module is used to control the reinforced buffer column 4 to perform deformation detection after the equipment is impacted.

[0037] When the monitoring value of the vibration sensor in this scheme is greater than the set value, the monitoring module controls all the reinforced buffer columns 4 to perform a deformation detection. During the deformation detection: turn on the laser receiver 402 and the laser transmitter 403. If the laser transmitter 403 does not receive the laser signal, it is judged that the reinforced buffer column 4 is deformed. At this time, the distribution board will cut off the power supply to the storage unit 2 associated with the reinforced buffer column 4.

[0038] When the number of reinforced buffer columns 4 detected as deformed exceeds the set value, the alarm module sounds an alarm, and the battery management module simultaneously cuts off power to all power storage units 2. That is, when a large range of reinforced buffer columns 4 are deformed, it is judged that the deformed area is large.

[0039] When the battery in this solution is subjected to an impact, the impact-resistant layer 3 can effectively disperse and buffer the impact force, thereby reducing the damage to the storage unit 2. The provision of the reinforced buffer column 4 further enhances the impact resistance of the battery, and through the synergistic effect of the elastic sealing tube 401 and the buffer block 404 inside it, more impact energy can be absorbed and dispersed.

[0040] After the battery is impacted, the emergency protection system of this solution will respond quickly, and the vibration sensor in the outer shell 1 will detect the impact signal and transmit the signal to the monitoring module. The monitoring module determines whether deformation detection is required based on the monitoring value of the vibration sensor. When the monitoring value exceeds the set value, the monitoring module will control all the reinforced buffer columns 4 in the outer shell 1 to perform a deformation detection;

[0041] During deformation detection, through the cooperation of the laser receiver 402 and the laser transmitter 403, if the laser receiver 402 normally receives the laser emitted by the laser transmitter 403, it is judged that the reinforced buffer column 4 is not deformed. If the laser receiver 402 does not receive the laser, it is judged that the reinforced buffer column 4 is deformed. At the same time, the monitoring module marks the reinforced buffer column 4, so as to quickly judge whether the reinforced buffer column 4 is deformed after being impacted.

[0042] If the reinforced buffer column 4 is detected to be deformed, the distribution board will immediately cut off the power supply to the storage unit 2 associated with the marked reinforced buffer column 4 to prevent the damaged storage unit 2 from affecting the overall circuit. When the number of deformed reinforced buffer columns 4 exceeds the set value, the alarm module will issue an alarm signal, and the battery management module will cut off the power supply to all storage units 2 to ensure the safety of the entire battery system.

[0043] In addition, in this solution, the battery management module in the distribution board can realize the association and control of multiple power storage units 2, and flexibly adjust the power-on and power-off states of the power storage units 2 according to the deformation of the reinforced buffer column 4. This can not only ensure the safety of the battery when it is impacted, but also improve the power utilization efficiency and service life of the battery.

[0044] In summary, the battery in this solution achieves comprehensive protection for the battery by adopting multiple protection measures such as the impact-resistant layer 3, the reinforced buffer column 4 and the emergency protection system.

[0045] Second implementation method:

[0046] Figure 5 It is shown that two pairs of guide channels are opened at the bottom end of the outer shell 1, a one-way valve is installed at the bottom end of the reinforced buffer column 4, an output pipe matching the one-way valve is installed on the guide channel, and matching docking joints are installed on the output pipe and the one-way valve. After the reinforced buffer column 4 is inserted into the impact-resistant layer 3, the one-way valve is docked with the output pipe; a guide pipe is connected between each pair of guide channels, and an air intake interface matching the guide channel is installed on the outer shell 1; optionally, the air intake interface is connected to an external air pump.

[0047] This embodiment further enhances the impact resistance of the battery by opening two pairs of guide channels at the bottom end of the outer shell 1 and installing a one-way valve at the bottom end of the reinforced buffer column 4 to achieve communication with the guide channels. This design enables the reinforced buffer column 4 to be inflated by an external air pump under certain conditions, thereby enhancing its buffering effect.

[0048] When deformation of the reinforced buffer column 4 is detected or the monitoring value of the vibration sensor exceeds the set value, the external air pump can be controlled to start, and the gas can be filled into the reinforced buffer column 4 through the air inlet interface and the output pipe. Since the elastic sealing tube 401 and the buffer block 404 are both made of elastic materials, the reinforced buffer column 4 will expand after inflation, thereby improving the buffering effect of the impact-resistant layer 3. This design can quickly enhance the buffering capacity when the battery is impacted, and effectively protect the storage unit 2 from damage;

[0049] In addition, the porous and breathable structure of the buffer block 404 allows the gas to quickly and easily fill the space in the elastic sealing tube 401, thereby ensuring the smooth progress of the inflation process; it not only ensures the buffering performance of the enhanced buffer column 4, but also makes the inflation process more efficient.

[0050] This embodiment further improves the impact resistance of the battery by adding structures such as a guide channel, a one-way valve and an air intake interface. This design can quickly enhance the buffering effect when the battery is impacted, effectively protect the power storage unit from damage, and improve the safety and reliability of the battery.

[0051] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
