[0024] It should be noted that the rainproof device of the present application can also be used on electric vehicles, and the rainproof device of the present application can be directly moved to the electric vehicle for use.

[0025] like Figure 1-4 As shown, a bicycle rainproof device is arranged on the bicycle body, specifically arranged at the position of the bicycle seat 2 and the rear seat 3, and specifically includes a fixed support frame 7 and a movable support frame 4. Among them, the fixed support frame 7 is fixedly arranged approximately horizontally from the bicycle seat to the direction of the rear seat 3 thereof, specifically, one end of the fixed support frame 7 is arranged close to the seat 2, and the other end extends in the direction of the rear seat 3. The above-mentioned fixed support frame is specifically fixed on the rear seat 3, and can be tied with wire or iron wire, or welded to the rear seat 3.

[0026] The above-mentioned movable support frame 4 is rotatably set on the vehicle body with a position close to the bicycle seat 2 as the rotation center. The rotation center and the seat 2 are located in a straight line. A flexible rainproof cloth 8 is provided between the movable support frame 4 and the fixed support frame 7. The flexible rainproof cloth 8 can be transparent or opaque. When the movable support frame 4 rotates counterclockwise around the rotation center, the flexible rainproof cloth 8 is opened. At this time, corresponding to a rainy day, the flexible rainproof cloth 8 can shelter the rider from rain; when the rain stops, the movable support frame 4 is operated to rotate clockwise around the rotation center, and the flexible rainproof cloth 8 is folded on the rear seat 3.

[0027] The rotation of the movable support frame 4 can be manually operated, such as Figure 1-2 As shown, when the rider feels it is raining, he stops the vehicle and manually rotates the movable support frame 4 so that the flexible rainproof cloth 8 is opened.

[0028] It should be noted that when the movable support frame 4 is manually rotated, the movable support frame 4 can be hooked by an external pulling component or a hook to prevent it from rotating when the flexible rainproof cloth 8 is opened.

[0029] Furthermore, the above-mentioned fixed support frame 7 and movable support frame 4 can be the following shape, that is, a U-shaped frame, the U-shaped fixed support frame 7 is symmetrically arranged on the left and right sides of the vehicle body, and the U-shaped movable support frame 4 is symmetrically arranged on the left and right sides of the vehicle body (that is, the perpendicular bisectors of the U-shaped fixed support frame 7 and the movable support frame 4 coincide with the perpendicular bisectors of the bicycle), and the two ends of the U-shaped movable support frame 4 are respectively rotatably arranged on the vehicle body near the seat cushion 2 through a rotating rod 5, and the two rotating rods 5 are arranged horizontally left and right, and the two rotating rods 5 are located in a straight line, one end of each rotating rod 5 is fixedly connected to one end of the U-shaped movable support frame 4, and the other end is directly inserted into the socket 6 set in the vertical beam 1 below the seat cushion 2, or square blocks 11 can be welded on the left and right sides of the seat cushion 2, and a socket 6 is set on the square block 11, and one end of the rotating rod 5 is rotated into the illustration socket 6.

[0030] Further, in one embodiment, if Figure 3 As shown, the rotation of the above-mentioned movable support frame 4 can be realized by electric means, therefore, a power unit is also included. The existence of the power unit can automatically realize the switch of the rainproof device. The rider can control the action of the power unit by only pressing the switch of the power unit. The above-mentioned power unit is arranged on one side of the seat cushion 2 and connected to one of the rotating rods 5 to drive the rotating rod 5 to rotate, thereby driving the entire movable support frame 4 to rotate around the rotation center.

[0031] Furthermore, in order to improve the rigidity of the flexible rainproof cloth 8 and avoid the flexible rainproof cloth 8 being crushed during heavy rain or rainstorm, a plurality of reinforcing frames 9 are provided on the flexible rainproof cloth 8. The plurality of reinforcing frames 9 are distributed in a fan-shaped manner with the rotation center of the movable supporting frame 4 as the rotation base point, and each reinforcing frame 9 is also U-shaped, and the two ends of the reinforcing frame 9 are arranged close to the rotation center.

[0032] In a further embodiment, the action of the power unit can be automatically realized by a sensor without manually pressing the switch. Therefore, a raindrop sensor 13 and a controller 10 are also provided. The controller 10 can be provided on the vertical beam 1 below the seat cushion 2 and facing forward, so that the controller 10 can be better protected. The raindrop sensor 13 is provided on the rear seat 3 of the vehicle body. When it is not raining, the flexible rainproof cloth 8 is folded, such as Figure 4 As shown, at this time, the rear seat 3 is not covered by the flexible rainproof cloth 8. Therefore, as long as it rains, raindrops fall on the raindrop sensor 13, and the raindrop sensor 13 can generate a signal. The raindrop sensor 13 is electrically connected to the controller 10 and transmits the signal to the controller 10. The controller 10 is also electrically connected to the power unit. When receiving the signal from the raindrop sensor 13, the controller 10 controls the power unit to operate.

[0033] In one embodiment, the power unit adopts a steering gear 12, which drives the rotating rod 5 to rotate. The steering gear 12 is adopted here because the steering gear 12 can output a rotation reaching a precise angle, and the output power is relatively small, which is suitable for the working scene here.

[0034] Furthermore, the radial length of the movable support frame 4 and the fixed support frame 7 is not less than the distance between the vehicle seat 2 and the handlebars of the vehicle body, so that the rain shielding area of ​​the flexible rain shield can be increased, and the rain shielding can be reliable, whether it is vertical rain or oblique rain, it can be well shielded.

[0035] Furthermore, in order to facilitate observation, the flexible rainproof cloth 8 is a transparent rainproof cloth.

[0036] The above-mentioned specific implementation manner cannot be used as a limitation on the protection scope of the present utility model. For those skilled in the art, any replacement, improvement or change made to the implementation manner of the present utility model falls within the protection scope of the present utility model.

[0037] The matters not described in detail in the present invention are all known technologies to those skilled in the art.
