The case of the battery pack 2 includes a body 2a and a guard step 2b formed on the upper surface of the body 2a with both sides of the width thereof being extended beyond the body to form a stepped structure. The pedal frame 1 is provided with a recessed groove k with an upward opening through which the battery case 2 can be inserted into the recessed groove k and from which the pedal frame 1 can be detached, and a resting portion surrounding the recessed groove k.

It will be appreciated that when the battery compartment 2 is inserted into the opening, the guard pedal rests on the rest. The upper surface of the battery case 2 is exposed to the upper surface of the pedal frame 1, that is, no other cover or shield covers the opening again. Therefore, the battery box 2 can be directly taken and placed from the opening, and the convenience of taking, replacing and maintaining is improved.

Therefore, the lower surface of the protective pedal 2b and the laying part form a combined surface, the combined surface is positioned below the protective pedal 2b, a longitudinal rainwater channel is reduced, rainwater is prevented from directly sprinkling on the combined surface, and the waterproof performance of the electric scooter is improved.

It should be understood that the protection pedal 2b is exposed out of the pedal frame 1 after the battery case 2 is inserted into the depressed groove k of the pedal frame 1. The protective pedal 2b provides a bearing part for a user to stand when riding and plays a role in protecting the internal battery pack from being impacted by force. Therefore, the protective pedal 2b is preferably made of a metal plate with a certain strength, and the metal plate can be provided with a silica gel cushion with a concave-convex structure to improve the friction between the rider and the pedal.

And, as shown in fig. 1-4, a side surface of the body 2a is provided with a slope p which is inclined from outside to inside from top to bottom, thereby forming a cavity at the front side thereof; the inclined plane p is provided with a first electrical interface 3 with a downward opening and communicated with the battery pack; the recessed groove is internally provided with a second electric interface 4 matched with the first electric interface, and the first electric interface and the second electric interface are positioned in the cavity. When the battery case 2 is fitted into the recess groove k, the first electrical interface 3 and the second electrical interface 4 are electrically connected to each other, so that the battery case 2 is electrically connected to an internal circuit of the electric scooter, and thus electric power support can be achieved.

The setting on inclined plane makes first electrical interface and second electrical interface sheltered from in the below, and the orientation of first electrical interface is downward, even if like this trace water gets into between battery case and the footboard frame, water still more difficult flows interface position department, has further improved electric scooter's waterproof performance.

Further preferably, as shown in fig. 2, the pedal frame 1 includes a U-shaped bottom frame 1a and an upper frame 1b, the upper frame 1b includes a horizontal plate h shaped like a Chinese character 'kou' and two vertical plates j extending downward from the front and rear sides, the vertical plates j cover the front and rear sides of the U-shaped bottom frame 1a, and the horizontal plate h is located on the upper portion of the U-shaped bottom frame 1 a.

As shown in fig. 2 to 3, the upper end surfaces of the left and right walls of the U-shaped bottom frame 1a have an inner resting portion e and an outer resting portion f, wherein the inner resting portion e is lower than the outer resting portion f. The edge of the protective pedal 2b is placed on the inner placing part e, and the transverse plate is placed on the outer placing part f. A water leakage groove is formed between the inner placing part e and the outer placing part f at intervals, and the waterproofness is further improved.

Preferably, the upper surface of the guard step is flush with the upper end surface of the upper frame to make the appearance of the step more beautiful.

As shown in fig. 2, preferably, the body 2a includes a case a1 opened at the upper side and a cover a2, the battery pack is packaged in the case a1 and the cover a2 in combination with the case a1 includes an annular flange protruding toward the outer peripheral wall at the upper end, and the periphery of the cover a2 is fixed to the annular flange to close the case a1.

Example two:
