Either mechanically or electrically. They may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.

The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

As shown in fig. 1 and 2, the utility model discloses a power-assisted electric vehicle, frame, setting are in the basket 3 in frame the place ahead sets up motor 4 on the vehicle front wheel for give battery 1 of 4 power supplies of motor, its characterized in that: a battery frame 2 is fixedly arranged in the basket 3, the battery 1 is detachably inserted into the battery frame 2, a plug 21 is arranged on the lower bottom surface of the battery frame 2, the plug 21 is electrically connected with the motor 4 through an electric wire, and a socket matched with the plug 21 is arranged at the bottom of the battery 1.

Specifically, the basket 3 is vertically connected to a head tube 6 in the frame, the battery rack 2 is disposed in the basket 3, the rear side of the battery rack 2 is closely attached to the rear side of the basket 3, and the basket 3 and the head tube 6 can be connected by welding or screwing.

The battery frame 2 with be equipped with the line hole of crossing that matches each other on the car tube head 6 battery 1 inserts when the battery frame 2, its internal line can be through crossing the line hole and changeing 5 and motor 4 realization electric connection. Therefore, the wire consumption is reduced, and the potential safety hazard caused by the fact that the wire is exposed in the air is avoided.

The motor 4 is positioned outside the front wheel of the power-assisted electric vehicle, so that the wire distance between the motor 4 and the battery 1 is greatly reduced, and the loss of a line in the transmission process is reduced. The turning handle 5 is arranged on the right handle bar of the frame, and a user can accelerate or decelerate the power-assisted electric vehicle by rotating the turning handle 5 during driving, which is the prior art and is not described herein again.

As shown in fig. 3, the battery holder 2 is larger than the battery 1 and has a plug 21 on its bottom surface, and the battery 1 is a rectangular parallelepiped and has a socket (not shown) on its bottom surface. The bottom surface design of the lower battery is matched with the bottom surface design of the battery rack 2, and the battery rack are integrally designed in a plug-and-play mode, so that the battery rack is very quick and convenient.

The bottom surface of the battery 1 is provided with a USB interface (not shown in the figure), and a user can take out the battery and connect the interface with other equipment to charge the equipment when the battery 1 is in an electrified state, so that the battery is multipurpose.

In addition, the bumping situation can not be avoided during the driving process, in order to prevent the poor contact caused by the shaking of the battery due to the special condition of the road surface and the convenience of the assembly, the outer side of the battery 1 is provided with a guide bar 11, and correspondingly, the outer side of the battery frame 2 is provided with a guide groove 22. When the battery 1 is inserted into the battery holder 2, the guide strip 11 is engaged with the guide groove 22, and the guide strip and the guide groove are constrained with each other to avoid the shaking.

In addition, a top cover 24 is provided above the battery holder 2. One side of the top cover is connected to one side of the battery holder using a pivot 25 so that the top cover can rotate about the connection. The cover is equipped with the torsional spring 23 that is used for making the top cap keep the closure state on the connecting axle, and torsional spring 23's its effect lies in: the top cover can be automatically closed without external force, dust can be isolated, and the dryness in the battery rack can be kept. The reason for designing the top cover is as follows: firstly, the battery can be restrained by covering the top cover in the running process, so that the battery cannot fall off due to road surface; secondly, in rainy and snowy weather, the circuit is not damaged because the rain and snow fall into the battery rack. When the battery is used, the top cover 24 is turned over, and the battery 1 is inserted, so that circuit communication can be realized. When the battery 1 is pulled out, the top cover 24 is automatically closed under the action of the torsion spring 23. Of course, sealing between the top cover 24 and the battery holder body is also indispensable, otherwise the sealing performance is weakened.
