The limiting hole 216 is U-shaped, and the threaded end of the locking rod 214 is located in the limiting hole 216. The middle part of the clamping plate 213 and the snap-fit ​​seat 211 are respectively wrapped around the support rods on both sides below the backrest 120, so as to make it easy to tightly clamp the support rods.

[0027] The dual-sided protective assembly 220 also includes a connecting cylinder 221. The back of the connecting cylinder 221 is fixedly installed on the back of the snap-fit ​​seat 211. The other end of the connecting cylinder 221 is internally threaded with a connecting screw 222. The back of the connecting screw 222 is fixedly connected with a hinge seat 224, which is hinged to one end of the handrail 226. A limiting nut 223 is sleeved on the external thread of the connecting screw 222. One side of the limiting nut 223 abuts against the outer end of the connecting cylinder 221. The limiting nut 223 is used to facilitate adjustment of the distance between the connecting screw 222 and the connecting cylinder 221, and also to facilitate fixing the distance.

[0028] The handrail 226 is L-shaped, with a hinge plate 225 fixedly connected to one short side. The hinge seat 224 is a chamfered rectangle with a rectangular through hole in the middle. The hinge plate 225 is hinged within the hinge seat 224. The rectangular shape facilitates the contact of the sliding cylinder 227, preventing unauthorized rotation. A sliding cylinder 227 is slidably fitted onto the end of the handrail 226 closest to the hinge plate 225. A contact ring 228 is fixedly fitted onto the end of the sliding cylinder 227 furthest from the hinge plate 225. A spring 229 is positioned between the contact ring 228 and the sliding cylinder 227. The spring 229 is fitted onto the handrail 226, and the contact ring 228 provides contact with the spring 229.

The other end of the sliding cylinder 227 is abutted against the hinge seat 224. The outer side of the handrail 226 has a part with a diameter that matches the inner ring, which facilitates the sliding of the sliding cylinder 227.

[0029] Working principle: Installation and fixing stage: First, attach the snap-fit ​​seat 211 and the clamping plate 213 in the limiting connection assembly 210 to the support rods on both sides below the backrest 120, so that the arc-shaped middle part of the snap-fit ​​seat 211 and the arc-shaped middle part of the clamping plate 213 wrap around the support rods; then rotate the locking rod 214 so that the threaded end of the locking rod 214 passes through the limiting hole 216 of the clamping plate 213, and thread the nut onto the outer end of the locking rod 214, and tighten the nut until it is in contact with the support rod. The clamping plate 213 abuts, completing the fixation of the snap-fit ​​seat 211 and the clamping plate 213 on the upright of the backrest 120; then adjust the double-sided protective components 220: rotate the connecting screw 222 to move it within the thread of the connecting cylinder 221 until the hinge seat 224 reaches the position that matches the width of the backrest, then tighten the limiting nut 223 on the outside of the connecting screw 222 so that one side of the limiting nut 223 abuts against the outer end of the connecting cylinder 221, fixing the position of the connecting screw 222.

[0030] During child use: When a child needs to ride, pull the handrail 226 outward to move it away from the hinge seat 224. Then, by rotating the handrail 226 in conjunction with the rotation of the hinge plate 225 within the hinge seat 224, the handrail 226 is positioned on both sides of the rear seat. At this time, the sliding cylinder 227 on the handrail 226, under the elastic force of the spring 229, is in contact with the hinge seat 224 at one end, ensuring the stability of the handrail 226 in its upright position. When the child is riding in the rear seat, their legs are positioned between the rear seat and the handrail 226, and their hands grip the handrail 130 at the front of the electric vehicle to achieve lateral restraint and balance maintenance.

[0031] Idle and auxiliary use stage: When children are not riding, if space needs to be saved, the handrail 226 can be rotated in the opposite direction and the handrail 226 can be folded down with the hinge plate 225. After folding, it fits the rear of the electric vehicle frame 110 without taking up extra space. If it is necessary to assist in carrying items, the handrail 226 can be opened to both sides, and items (such as shopping bags or school bags) can be placed in the space between the two handrails 226. The items can be restrained by the handrail 226 to prevent them from falling during the carrying process.
