Problems solved by technology

[0003] Most of today's new energy electric vehicles are powered by battery packs. During the use of new energy electric vehicles, the battery may have abnormal conditions, such as excessive external temperature, long-term work, and being scratched by sharp objects on the ground. Cause damage or open circuit of the battery, which will lead to thermal runaway of the battery and cause the battery to spontaneously ignite. Since the batteries in the battery pack are generally fixed together and cannot be separated, the self-igniting battery will easily increase the temperature of the normal battery, further increasing safety hazards. And if the abnormal battery is not replaced in time, the entire battery pack will not be able to supply power normally, which will cause the new energy electric vehicle to stay on the road for a long time, which will easily cause safety accidents

Embodiment 1

[0032] Such as Figure 1-6 As shown, an automatic replacement device for an abnormal battery of a new energy vehicle includes a casing 1, in which a plurality of first cavities 2 are arranged, and an electric connection plate 3 is arranged on the inner top surface of the upper end of the first cavity 2, And the inner top surface of the lower end of the first cavity 2 is provided with an elastic connecting plate 4 matched with the electric connecting plate 3, and the upper surface of the elastic connecting plate 4 has a certain radian, which is convenient for pushing the spare battery 10 to squeeze the elastic connecting plate 4 to realize butt.

[0033] A battery 5 is electrically connected between the electric connecting plate 3 and the elastic connecting plate 4, the first cavity 2 communicates with the second cavity 6 and the receiving cavity 7, a pushing mechanism 8 is set in the second cavity 6, and the pushing mechanism 8 The output end of the output end extends into th...

Embodiment 2

[0040] Such as Figure 7-8 As shown, the difference between this embodiment and Embodiment 1 is that a slide bar 18 is slidably connected to the arc-shaped push block 9, and one end of the slide bar 18 is fixedly connected with a clamp block 19, and the clamp block 19 is in contact with the spare battery 10 Connection, a plurality of second tension springs 20 are fixedly connected between the slide bar 18 and the arc-shaped push block 9, and the slide bar 18 is attracted to the second electromagnet 15, and the set slide bar 18 and the second tension spring 20, under the pulling force of the second tension spring 20, the clamp block 19 can clamp the backup battery 10 to ensure the stability of the backup battery 10 during push and docking. In addition, the sliding rod 18 and the second electromagnet 15 Cooperate, when the second electromagnet 15 is re-energized to generate magnetism, its magnetic force can be used to attract the slide bar 18 to drive the clamp block 19 away fro...

Abstract

The invention belongs to the field of new energy vehicles, and particularly relates to a new energy automobile abnormal battery automatic replacement device. The device comprises a shell, wherein a plurality of first cavities are formed in the shell; an electric connecting plate is arranged on the inner top surface of the upper end of the first cavity; an elastic connecting plate matched with theelectric connecting plate is arranged on the inner top surface of the lower end of the first cavity; a battery is electrically connected between the electric connecting plate and the elastic connecting plate; the first cavity is communicated with a second cavity and a storage cavity; a pushing mechanism is arranged in the second cavity; and the output end of the pushing mechanism extends into thefirst cavity and is fixedly connected with an arc-shaped pushing block. According to the invention, a first electromagnet and a second electromagnet are arranged, when the battery is powered off abnormally, the abnormal battery can be automatically removed and stored in cooperation with the pull rod and the pushing mechanism, a standby battery can be rapidly connected with the circuit at the sametime, and the driving safety is effectively guaranteed.

Description

technical field [0001] The invention belongs to the field of new energy vehicles, and in particular relates to an automatic replacement device for an abnormal battery of a new energy vehicle and a method for using the same. Background technique [0002] New energy vehicles, also known as alternative fuel vehicles, include pure electric vehicles, fuel cell electric vehicles and other vehicles that use non-petroleum fuels, as well as hybrid electric vehicles, ethanol gasoline vehicles and other vehicles that partially use non-petroleum fuels. [0003] Most of today's new energy electric vehicles are powered by battery packs. During the use of new energy electric vehicles, the battery may have abnormal conditions, such as excessive external temperature, long-term work, and being scratched by sharp objects on the ground. Cause damage or open circuit of the battery, which will lead to thermal runaway of the battery and cause the battery to spontaneously ignite. Since the batterie...
