Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

Please refer to FIG. 1 to FIG. 11 , the present invention provides an electric delivery vehicle, including:

Vehicle body 1, there are two batteries 3 on the vehicle body 1, and a switch button connected to the two batteries 3 is arranged on the vehicle body 1. The switch button can be arranged near the instrument panel of the vehicle body 1 to facilitate operation, The switch button is assembled so that when any one of the two storage batteries 3 is insufficient in power, the other storage battery 3 can supply power to the takeaway electric vehicle by operating the switch button;

A plurality of charging units 171 are arranged in a special electric cabinet 17 for power exchange, respectively for charging a plurality of backup batteries 3;

Wherein, the special electric cabinet 17 for battery swapping enables when there is a battery 3 with insufficient power in the vehicle body 1, it is replaced by a spare battery 3 in a certain charging unit 171, and the replaced battery 3 is put into the corresponding charging unit 171 for charging , and cooperates with the dual batteries 3 on the vehicle body 1 that can be switched for power supply, so that the takeaway electric vehicle has the function of one for use, one for backup and one for charging.

The two-contact module 21 moves with the battery 3 .

The above technical solution is adopted, so that after the battery 3 is put into the battery box 2 and installed, during use, the first contact module 31 of the battery 3 and the second contact module 21 in the battery box 2 pass through the locking assembly. 6. The connection is fixed so that the second contact module 21 and the battery 3 are integrated. When the battery box 2 has a very stable fixing effect on the battery 3, the battery 3 is stable. The first contact module 31 and the second contact module 21 The overall stability is also good. When the battery box 2 or the casing 4 of the battery 3 is deformed or worn due to long-term use, when the battery 3 shakes in the battery box 2, the second contact module 21 will follow the battery 3 to move synchronously. There is no relative displacement between the first contact module 31 and the second contact module 21, and further, the first contact module 31 and the second contact module 21 can be effectively prevented from being damaged due to relative movement. When the takeaway electric vehicle is used for a long time, the internal power supply circuit can maintain good electrical conductivity. Compared with the prior art, the first contact module 31 and the second contact module 21 are twisted or deformed due to the shaking of the battery 3. The conductive performance of the power circuit of the takeaway electric vehicle may cause hidden dangers, and even lead to power loss during the riding process during long-term vibration. The advantages of this solution are obvious;

Especially in the operation process, this solution is well matched with the replacement process of the battery 3, that is, when the battery 3 is replaced, when the battery 3 is lifted by the handle 8, the locking lever 61 is in the unlocked state, and when the battery 3 is put in, the lock lever 61 is in the unlocked state. After the battery box 2, the handle 8 is released, and the locking lever 61 is automatically switched to the locked state. At the same time, this solution simultaneously realizes the connection of the first contact module 31 and the second contact module 21 and the two functions of the locking assembly 6 locking the second contact module 21 and the battery 3, which is easy to operate and has strong practicability. .
