The bottom of the adjusting connecting rod 1 52 is provided with a bearing frame 2 53. The bearing frame 2 53 is rotatably connected with a contact bearing 2 54 near the driving cam 32. The contact bearing 1 50 and the contact bearing 2 54 are respectively used to contact the outer wall and the inner wall of the driving cam 32. When the driving cam 32 rotates and its outer wall rolls with the contact bearing 1 50, the driving cam 32 pushes the driving rod 33 to move upward. When the driving cam 32 rotates, When the driving cam 32 moves and its inner wall rolls with the contact bearing 2 54, the driving cam 32 pulls the driving rod 33 to move downward. When the outer wall of the driving cam 32 leaves the contact bearing 1 50 and the inner wall does not contact the contact bearing 2 54 or the inner wall of the driving cam 32 leaves the contact bearing 2 54 and the outer wall does not contact the contact bearing 1 50, the driving rod 33 is in a stationary state. During the continuous rotation of the driving cam 32, the distance between the contact bearing 1 50 and the contact bearing 2 54 determines the stationary time of the driving rod 33. An adjusting connecting rod 1 52 is provided inside one side of the bearing frame 2 53 and the bearing frame 1 51. A fixing block 58 is fixed to the middle of the inner side of the front wheel shaft 27, and springs 59 are connected to both sides of the fixing block 58.

The second driving rope 70 is wound around the plurality of second guide wheels 71. When the spring 4 63 is in a natural state When the driving rod 33 needs to be driven to move by the driving cam 32, the rider pulls the second driving rope 70 through the adjusting portion 31, thereby pulling the adjusting connecting rod 2 61 to move vertically upward. At this time, the adjusting connecting rod 2 61 compresses the spring 3 62. When the adjusting connecting rod 2 61 is gradually pulled out of the connecting inclined hole 69 on the inner side of the driving connecting rod 60, the bottom of the adjusting connecting rod 61 is in contact with the connecting rod 60. The cooperation of the inclined hole 69 will drive the driving connecting rod 60 to move toward the outside of the front wheel axle 27, thereby driving the adjusting ring 68 to move outward to make it close to the contact bearing 1 50 and the contact bearing 2 54, so that its movement can drive the driving rod 33 to move up and down through the contact bearing 1 50 and the contact bearing 2 54. When the driving rod 33 does not need to rotate, the second driving rope 70 is loosened to reset it under the action of the spring three 62. During the resetting process, the driving connecting rod 60 is gradually pushed to move toward the inside of the front wheel axle 27, so that it is away from the contact bearing 1 50 and the contact bearing 2 54.

[0031] Please refer to Fig.16The transmission part 30 also includes a speed adjustment mechanism, which includes a plurality of separation pulley blocks 73 that can be separated from each other. When the plurality of separation pulley blocks 73 are away from each other, their outer diameters become larger. At this time, when the plurality of separation pulley blocks 73 are rotated relative to the state in which their outer diameters are smaller, the rotation speed of the transmission pulley 39 will increase, thereby increasing the rotation speed of the wiper 24 and the rain wiping speed. When the plurality of separation pulley blocks 73 are close to each other, their outer diameters become smaller. At this time, when the plurality of separation pulley blocks 73 are transmitted relative to the state in which their outer diameters are larger, the rotation speed of the wiper 24 can be reduced; a connecting sleeve 75 is fixed to the end of the rotating shaft 36 near the separation pulley block 73, and a driving shaft 74 is slidably connected to the inner side of the connecting sleeve 75.

The cam 72 is provided with a plurality of guide strips 83 which are adapted to the guide strips 83. The guide strips 83 are provided on the inner wall of the guide strips 83 so as to be slidably connected to the outer wall of the tapered shaft end 82. When the drive shaft 74 is away from the separation pulley block 73, the plurality of separation pulley blocks 73 are moved away from each other under the action of the tapered shaft end 82, and their overall outer diameters become larger. When the drive shaft 74 is close to the separation pulley block 73, the plurality of separation pulley blocks 73 are moved close to each other under the action of the tapered shaft end 82, and their overall outer diameters become smaller, thereby achieving a speed regulation effect.The end of the driving shaft 74 away from the separation pulley block 73 is inserted into the inner side of the rotating shaft 36, and the end of the driving shaft 74 close to the rotating shaft 36 is sleeved with a spring 5 76.

[0033] The specific working principle of the bicycle with a shed provided by the present invention is: When riding, when encountering rainy days or other weather that requires protection, the foldable canopy part 2 can be unfolded for use. The unfolding process is: first, the foldable canopy part 2 is taken out from the inner side of the guard plate 19, and the foldable frame 4 is unfolded, the connector 5 is buckled on the positioning connecting column 22, and the two are fastened and positioned by the fixing screws 17, and then the support plate 11 is pulled out of the receiving groove to unfold the rain sheet 12, and the Velcro surface 15a and the Velcro surface 2 15b between the adjacent rain sheets 12 in the front and rear directions are fitted to each other, and at the same time, the positioning studs on the support plate 11 are fixed to the positioning screw holes of the support rod 13, and the connecting strips 16 on the adjacent support plates 11 are buckled on the corresponding positioning holes; when the rain sheet 12 is not in use, it is folded and stored in the receiving groove, and the foldable canopy part 2 is folded and stored to the inner side of the guard plate 19; When it is necessary to wipe the rain with the wiper 24, the rider pulls the second driving rope 70 through the adjusting portion 31, thereby pulling the adjusting connecting rod 2 61 to move vertically upward. At this time, the adjusting connecting rod 2 61 compresses the spring 3 62. When the adjusting connecting rod 2 61 is gradually pulled out from the connecting inclined hole 69 on the inner side of the driving connecting rod 60, due to the cooperation between its bottom and the connecting inclined hole 69, it will drive the driving connecting rod 60 to move outward from the front wheel axle 27, thereby driving the adjusting collar 68 to move outward to make it close to the contact bearing 1 50 and the contact bearing 2 54, so that its movement can drive the driving rod 33 to move up and down through the contact bearing 1 50 and the contact bearing 2 54, thereby driving the driving rod 33 to move up and down ... The movable rack 34 makes up-and-down reciprocating motion, thereby driving the driving gear 35 to reciprocate, and then driving the driving pulley 37 to reciprocate, and then driving the driving pulley 1 39, the first bevel gear 38, the second bevel gear 42, the transmission rod 1 43, the third bevel gear 44, the fourth bevel gear 45, the driving pulley 2 47, and the wiper 24 to reciprocate, thereby achieving the reciprocating rain-wiping effect of the wiper 24. When the driving rod 33 does not need to rotate, the second driving rope 70 is loosened to reset it under the action of the spring 3 62. During the resetting process, the driving connecting rod 60 is gradually pushed to move toward the inner side of the front wheel shaft 27, so that it is away from the contact bearing 1 50 and the contact bearing 2 54. When the rotation speed of the wiper 24 needs to be adjusted, the rider pulls the third drive rope 72 through the adjustment portion 31, thereby pulling the drive shaft 74 to perform displacement movement. When the drive shaft 74 is away from the separation pulley block 73, the plurality of separation pulley blocks 73 move away from each other under the action of the tapered shaft end 82, and their overall outer diameter becomes larger. When the rider gradually loosens the third drive rope 72 through the adjustment portion 31, the drive shaft 74 gradually returns to its original position under the action of the spring five 76. At this time, the drive shaft 74 gradually approaches the separation pulley block 73. Under the action of the tapered shaft end 82, the plurality of separation pulley blocks 73 move toward each other, and their overall outer diameter becomes smaller, thereby achieving a speed adjustment effect. When it is necessary to adjust the interval time of the reciprocating wiper 24, the rider pulls the first drive rope 56 through the adjustment part 31 to make it move vertically upward. When it moves vertically upward, it drives the contact bearing 2 54 to approach the contact bearing 1 50, thereby adjusting the distance between the two, thereby achieving the adjustment effect. When the rider releases the first drive rope 56, the bearing frame 2 53 is reset under the action of the spring 1 55.
