[0035] Embedded Structure 12

[0036] Please continue reading Figure 4 , Figure 4 This is a three-dimensional cross-sectional view of the optimal embodiment of the embedded structure of the utility model. Figure 4 As shown, the embedded structure 12 includes a guide rod 121; wherein the guide rod 121 is arranged in the hidden groove 11, and the hidden groove 11 is provided on the protective side plate, that is, the guide rod 121 is embedded in the protective side plate. A sliding groove 122 is provided on the bottom surface of the guide rod 121; specifically, the guide rod 121 is hollow at the bottom, wherein the sliding groove 122 forms a sliding cavity in the guide rod 121; and guide grooves 123 are provided on both sides of the sliding cavity. A stop hole 124 is provided on one side of the guide rod 121; wherein the stop hole 124 is connected to the sliding cavity.

[0037] Leg structure 13

[0038] Please continue reading Figure 5 , Figure 5 This is a three-dimensional diagram of the optimal embodiment of the leg structure of the utility model. Figure 5 As shown, the leg structure 13 includes an inclined rod 131; wherein the bottom of the inclined rod 131 extends below the sliding groove 122; and guide blocks 133 are fixed on both sides of the inclined rod 131; the inclined rod 131 can slide in the guide groove 123 through the guide blocks 133 to achieve telescopic movement in the sliding groove 122, wherein the guide blocks 133 are embedded in the guide groove 123. A connecting piece 132 is fixed at the bottom of the inclined rod 131; the connecting piece 132 is used to contact the ground, wherein the bottom surface of the connecting piece 132 is provided with anti-slip grooves 15 with equal spacing. A dynamic hole 134 and a static hole 135 are provided on the inclined rod 131; wherein the inner contours of the dynamic hole 134, the static hole 135 and the stop hole 124 are the same. During the driving of the electric vehicle, the dynamic hole 134 is flush with the stop hole 124, and most of the inclined rod 131 is received in the guide rod 121. At this time, the connecting piece 132 can be used as a footrest for rear passengers. When the electric vehicle needs to be parked in a fixed position on the bottom surface, the static hole 135 is flush with the stop hole 124. At this time, most of the inclined rod 131 is extended out of the guide rod 121, and the connecting piece 132 is against the bottom surface.

[0039] Locking structure 14

[0040] Please continue reading Figure 6 , Figure 6 This is a three-dimensional diagram of the optimal embodiment of the locking structure of the utility model. Figure 6As shown, the locking structure 14 includes an insert rod 141; a corner block 142 is fixed to one end of the insert rod 141; and a push piece 143 is installed on one side of the corner block 142; wherein one end of the corner block 142 passes through the slide groove 15 and extends to the outside of the rear section 1; and the inner contours of the dynamic hole 134, the static hole 135 and the stop hole 124 coincide with the outer contour of the vertical section of the insert rod 141. A spring tube 144 is fixed to one side of the corner block 142; the other end of the spring tube 144 is fixedly connected to one side of the slide groove 15. In the natural state, the spring tube 144 pushes the insertion rod 141 into the stop hole 124. It should be specifically explained that during the electric vehicle formation process, one end of the insertion rod 141 passes through the stop hole 124 and extends into the dynamic hole 134. At this time, the support leg is in a hidden state, and the top surface of the guide block 133 and the top surface of the guide groove 123 are against each other; when the electric vehicle needs to be parked, the user needs to slide the push piece 143 with his foot to compress the spring tube 144. At this time, the insertion rod 141 is pulled out and the inclined rod 131 slides down until the bottom surface of the guide block 133 and the bottom surface of the guide groove 123 are against each other, so that the force on the push piece 143 can be removed, and the spring tube 144 rebounds, pushing the insertion rod 141 through the stop hole 124 and into the static hole 135. At this time, the connecting piece 132 is against the bottom surface.

[0041] The utility model also provides an electric bicycle, a battery, a wheel and the frame 100 as described above; wherein the wheel is arranged at the front section 3 and the rear section 1; and the battery is arranged at the middle section 2.

[0042] In summary, by hiding the outrigger structure 13, accidental injury to the user during the pushing and driving of the electric vehicle can be avoided; by setting the connecting piece 132, the static support function and the driving support function can be realized; by setting the locking structure 14, the two states of the outrigger structure 13 can be easily switched, thereby reducing the difficulty of parking the electric vehicle.
