detailed description

The specific implementation of the present invention will be described in further detail below in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.

As shown in Figures 1 to 4, this embodiment provides an electric scooter with replaceable batteries, which includes a battery 1 and a battery cavity 2 for placing the battery 1. A battery box base 3 is fixedly installed at one end of the battery 1. The battery box base is provided with a limit hole 31, and the electric scooter is also provided with an electric control lock 4. The electric control lock 4 includes an electric control lock cylinder 41 for cooperating with the limit hole 31 to perform the locking or unlocking action of the battery 1 ；

A fixing seat 5 is installed in the battery cavity 2 at a position corresponding to the battery box base 3. The fixing seat 5 is provided with an ejection mechanism for pushing the battery box base end of the battery 1 out of the battery cavity 2 when the battery 1 is in an unlocked state.

When the battery needs to be replaced, the maintenance personnel can open the electric control lock through the APP, and the electric control lock core is pulled out from the limit hole of the battery box base. The battery is ejected out of the battery cavity under the action of the ejection mechanism at the bottom of the fixing base for maintenance. The person takes out the battery, unplugs the power cord, and then connects the new battery (a fully charged battery) to the power cord, puts it in the battery cavity of the car body, presses the base end of the battery box, and the electric lock cylinder automatically locks the battery. It should be noted that the electric control lock in this embodiment and the technical solution of opening the electric control lock through the APP terminal can be realized by the existing technology.

The electric scooter can quickly remove the battery from the body. When the power is exhausted, a fully charged battery can be replaced, and then the battery can be charged centrally, thereby reducing the workload of maintenance personnel and improving the efficiency of battery replacement.

In this embodiment, the ejection mechanism includes a spring ejection mechanism formed by connecting an ejection pin 51 and a spring 52. The retracting and ejecting action of the ejector pin 51 can be realized by the action of the spring 52. The spring ejection mechanism is easy to implement and low in cost.

As shown in Figures 1 and 2, the bottom of the fixing seat of this embodiment is provided with two sets of spring ejection mechanisms. The ejection pin 51 can be ejected or retracted in the vertical direction under the action of the spring 52. The outer end surface has a T-shaped structure, which is used to cooperate with two sets of spring ejection mechanisms to realize the ejection of the battery.

The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. It should be pointed out that for those of ordinary skill in the art, they can also do the same without departing from the technical principles of the present utility model. Several improvements and modifications have been made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
