Description

High security swing car Technical Field The invention relates to the technical field of toy vehicles for children, in particular to a high-safety swing car. Background The swing car is also called as a swing car, is a child toy with ingenious, flexible and interesting structure, does not need power sources such as a battery, a motor and the like, does not need manual pushing or double-foot support sliding, and can be driven forwards by only taking the child to continuously rotate a steering wheel left and right. Currently, swing cars with backrests can be broadly classified into three types, the first type is a fixed type backrest, the backrest and the seat are integrally designed, usually in an injection-molded or blow-molded integral structure, the backrest is an extension part of the rear part of the seat, and the backrest cannot be independently detached or adjusted. The second type is a foldable/detachable backrest, which is connected to the vehicle body by a hinge, a buckle or a quick-release structure, and can be folded to the side of the vehicle body or completely detached. The third type is an angle-adjustable backrest, an adjustable joint (such as a rotating shaft and a locking device) is adopted between the backrest and the vehicle body, and a user can adjust the inclination angle (such as 90 degrees, 100 degrees, 110 degrees and the like) of the backrest according to requirements. The three types of swing car backrests are usually installed at a later position, and the older children cannot provide effective support for the backrests when riding, and are not matched with the gravity centers of the children, so that the leaning bodies are inclined forwards or the gravity centers of the children are unstable. In addition, the design of the swing car guardrail has the following three problems, namely, the guardrail or the fence of the existing swing car is generally low in height (such as to the waist of a child or lower), and the guardrail or the fence cannot effectively block the child who is active or tries to stand up. Secondly, some guardrails or barriers are only arranged at the rear or one side of the seat, a complete enclosing structure is not formed, and children can easily turn over from the side or the front. Thirdly, most guardrails or enclosing barriers are of fixed structures, so that the use state of the swing car is inconvenient to convert, and the guardrails or enclosing barriers with detachable structures are complex in structure, so that the assembly and the disassembly are complicated, and the manufacturing cost is high. Disclosure of Invention In view of the above, the invention provides a high-safety swing car, which can effectively overcome the defect that the backrest of the existing swing car cannot provide effective support for children after being too far back, and can solve the safety problem of children with small ages when riding. A high-safety swing car is characterized in that a seat surface of a swing car body consists of a fixed part and a movable part, when a backrest is needed to be used, the movable part is separated from the fixed part in a turnover or disassembly mode and is opened, the movable part is matched and locked with the fixed part to form a fixed backrest of the swing car, a fence connecting assembly is detachably arranged on the back of the fixed backrest, a supporting rod is detachably connected to the fixed part of the seat surface, two ends of two half fences are respectively assembled with the matched parts of the fence connecting assembly and the supporting rod to form a closed fence, after the half fences and the supporting rod are disassembled, the fixed backrest is unlocked and turned to be closed, and the movable part and the fixed part of the seat surface form the complete seat surface of the swing car. Further, the body of the swing car comprises an upper body, a lower body, a cover plate backrest, a locking screw and unlocking buttons; an unlocking button is arranged in the middle of one end of the cover plate backrest, a inserted bar structure extends out of the left side and the right side of the other end along the horizontal direction, and a kidney-shaped hole is formed in the inserted bar structure; The locking screw rod penetrates through the kidney-shaped hole in the cover plate backrest inserting rod structure to movably connect the cover plate backrest with the upper vehicle body, and the cover plate backrest is locked and unlocked with the lower vehicle body through the unlocking button; the middle part of lower automobile body is equipped with the spacing groove, lifts when the anticlockwise upset of apron back reaches the settlement angle, inserts the apron back in the spacing groove of lower automobile body again and forms fixed back, and when the apron back need drop, lifts the apron back along the direction of spacing groove, makes it break away from the spacing groove and then clockwise upset until laminating with lower a
