The battery is arranged on the frame diagonal rod, so that the structural advantages of the bicycle are retained, the battery cannot be heavy due to installation, and the structure has the advantages of the existing electric vehicle and the existing bicycle.

As an improvement to the above scheme, the locking mechanism comprises a movable clamping tongue mounted on the inner wall of the upper end face of the battery jar, a lock cylinder capable of driving the movable clamping tongue to stretch and retract, and an elastic top column arranged at the bottom of the battery jar, wherein a lock hole of the lock cylinder is positioned on the outer side wall of the inclined rod, and a clamping table matched with the movable clamping tongue is arranged on the end face of the battery. The lower end face of the battery jar is provided with a positioning column which is convenient for installing, positioning and fixing the lower end of the battery, and the lower end of the battery is provided with a positioning hole matched with the positioning column. The upper end of the battery is positioned in the battery jar through the clamping tongue, and the lower end of the battery is stably fixed in the battery jar through the positioning column, so that the whole battery is stably installed. Meanwhile, the battery can be prevented from being stolen by arranging the lock cylinder.

As a further improvement to the above solution, in order to prevent rainwater from flowing into the battery electrical connection part, the electrical connection terminal is a male terminal higher than the lower end surface of the battery jar, and even if rainwater enters the battery jar, the rainwater cannot directly enter the charged part.

For the battery 4 to be installed more smoothly, the cross sections of the battery and the battery groove are mutually matched and provided with the guide inclined planes which are convenient for the battery to be accurately clamped into the battery groove, and the smoothness of the clamping of the battery can be increased through the guide inclined planes.

Detailed Description

To facilitate understanding of those skilled in the art, the present invention will be described in further detail with reference to specific embodiments and drawings.

Please refer to fig. 1-5 for a preferred embodiment of the present invention.

The overall appearance of the frame structure of the electric vehicle disclosed by the embodiment is similar to that of the frame of the existing bicycle, and meanwhile, the battery can be installed. The frame comprises a frame cross rod 1, a vertical rod 2 and an inclined rod 3, wherein the cross rod 1, the vertical rod 2 and the inclined rod 3 are fixed in a triangular mode to form a stable structure.

In order to facilitate the mounting of the battery 4, a battery case 31 for mounting the battery 4 is provided in the diagonal member 3. The battery container 31 is provided with an electrical connector 32 at the lower end thereof, and the battery 4 is provided with an electrical receptacle (not shown) at the lower end thereof for mating with the electrical connector 322. In this embodiment, the electrical connector 32 is a male connector and is higher than the lower end surface of the battery container 31, and this structure can effectively prevent rainwater from entering the electrical connector to cause short circuit. In addition, a positioning post 311 is disposed on the lower end surface of the battery container 31 for facilitating the installation, positioning and fixing of the lower end of the battery 4, a positioning hole (not shown) is disposed at the lower end of the battery 311 for matching with the positioning post 311, and a locking mechanism 33 is also disposed at the upper end of the battery container 31 for fixing and locking the battery 4 in the battery container 31, so as to fix the upper end and the lower end of the battery 4 in the battery container 31.

The locking mechanism 33 in this embodiment includes a movable latch 331 installed on the inner wall of the upper end surface of the battery container 31, a lock core (not shown) capable of driving the movable latch to extend and retract, and an elastic top post 332 disposed at the bottom of the upper section of the battery container 31. Meanwhile, a clamping table 334 matched with the movable clamping tongue 331 is arranged on the upper end face of the battery 4, and the movable clamping tongue 331 can be clamped in the clamping table 334. Because the battery 4 is shaken after being installed in the battery slot 31 due to the errors of the processing and assembling process, the elastic top column 332 can apply force outwards to prop against the upper section of the battery 4, and the battery 4 can be prevented from shaking in the battery slot 31 by applying force in the direction opposite to the direction of the movable clamping tongue 331. The lock hole 333 of the lock cylinder is positioned on the outer side wall of the diagonal rod 3, and rainwater can be prevented from flowing into the lock hole 333.

Because battery 4 and battery jar 31 are harder parts, easy jam and the location is not accurate and produce crooked condition in the battery 4 installation, for make battery 4 install more smoothly, the location is more accurate. The battery 4 and the battery container 31 are matched to each other in cross section and have guide ramps 41 which facilitate the snapping-in of the battery 4 into the battery container 31. As shown in the drawing of this embodiment, the guide inclined surface 41 is designed such that the battery 4 and the battery container 31 are substantially triangular. When the battery 4 is inserted into the battery container 31, the lower end of the battery 4 is first inserted into the battery container 31, the electrical connector 32 is abutted with an electrical receptacle (not shown) at the lower end of the battery 4, and the upper end of the battery 4 is then pushed into the battery container 31 and locked by the locking mechanism 33. During the pushing of the battery 4 into the battery container 31, the battery 4 can be inserted into the battery container 31 in a well-matched manner without being easily tilted due to the restriction and guidance of the guide slope 41.

While the invention has been described in conjunction with the specific embodiments set forth above, it is evident that many alternatives, modifications, and variations will be apparent to those skilled in the art in light of the foregoing description. Accordingly, it is intended to embrace all such alternatives, modifications, and variations that fall within the spirit and broad scope of the appended claims.
