Description

Technical Field

[0001] The invention relates to a wind and rain canopy for an electric vehicle, in particular to a skeleton structure of a wind and rain canopy for an electric vehicle. Background Art

[0002] Electric bicycles are popular among consumers for their convenience and environmental protection. Since electric bicycles do not have a wind and rain canopy, it is inconvenient to ride a bicycle when it is windy and rainy, and wearing a raincoat blocks the view and affects safety. Therefore, the invention with announcement number CN207389390U discloses an electric bicycle safety protection device, including two parallel arc-shaped steel pipes as the main skeleton of the protection device, the arc-shaped steel pipe includes a front part, an upper part and a rear part, the front and rear parts have a larger arc curvature, and the upper part is relatively straight; the front end and the rear end of the arc-shaped steel pipe are aligned with the electric bicycle. The front and rear of the electric bicycle are fixedly connected, and the two arc-shaped steel pipes are connected as a whole by a plurality of transverse steel pipes between the two arc-shaped steel pipes. The arc-shaped steel pipes and the transverse steel pipes are wrapped with flexible protective sleeves. A flexible pressure-resistant plate is fixed on the outside of the two arc-shaped steel pipes. The width of the flexible pressure-resistant plate is greater than the spacing between the two arc-shaped steel pipes. The edge of the flexible pressure-resistant plate is wrapped with a soft edging. The front of the flexible pressure-resistant plate corresponds to the position of the front of the electric bicycle. A window is provided at the position of the flexible pressure-resistant plate corresponding to the front of the electric bicycle, and tempered glass is installed on the outside of the window. The above structure forms protection on the front, rear and top of the electric bicycle, which can effectively protect cyclists and pedestrians in the event of a minor collision and reduce the damage caused by the accident to the human body. At the same time, the present invention also takes into account the role of sunshade and rain shield. At the same time, the wind resistance during driving is reduced by changing the curvature of the unused parts of the arc-shaped steel pipe.

[0003] Since the arc-shaped steel pipe of the above-mentioned safety protection device serves as the main frame of the protection device, and a protective cover is arranged on the outside of the frame, the assembly is relatively complicated. Different vehicle models have different lengths and installation positions. The arc-shaped steel pipe needs to be matched for each vehicle model, which is inconvenient to process. At the same time, the arc-shaped steel pipe is too long to be transported, which affects the promotion and application of the product. In addition, when a serious traffic accident occurs, there is a risk of secondary injury when the arc-shaped steel pipe is bent. Summary of the invention

[0004] The purpose of the present invention is to provide a skeleton structure of a wind and rain canopy for an electric vehicle. The two arc-shaped main skeletons are connected by segmented pipes made of plastic materials. The two arc-shaped main skeletons are connected by a plurality of plastic cross bars to maintain stability. According to different vehicle models, only one section of the segmented pipe needs to be replaced to match it, and the adaptability is greatly improved. The present invention is convenient for transportation due to the segmentation, which is conducive to promotion and application. The skeleton connected by plastic materials can effectively reduce the risk of secondary damage compared with the metal tube skeleton when it breaks.

The plug-in column is plugged into the receiving hole. Screw holes and through holes are respectively opened at positions corresponding to the plug-in column and the receiving hole. The screws pass through the through holes and are screwed on the screw holes to securely connect the front section pipe and the upper section pipe.

[0008] The upper end of the longitudinal U-shaped fixing tube is connected to the lower ends of the two rear section tubes at the same time through a connecting sleeve; a connecting column is provided at the upper end of the longitudinal U-shaped fixing tube, and a connecting column is also provided at the lower end of the rear section tube. The upper and lower ends of the connecting sleeve are respectively sleeved on the connecting columns at the upper end of the longitudinal U-shaped fixing tube and the lower end of the rear section tube. The connecting sleeve is provided with a through hole at the position of the screw hole of the side wall of the connecting column at the upper end of the longitudinal U-shaped fixing tube and the lower end of the rear section tube.
