[0002] A power-assisted bicycle is a common means of transportation that combines human power and auxiliary power. It usually includes two types: fuel-assisted bicycles and electric bicycles. The overall structure of a power-assisted bicycle is similar to that of a bicycle, but there are some differences in details. For example, a power-assisted bicycle is equipped with a motor, battery, and control motherboard, which can provide additional propulsion on difficult roads such as uphill, thereby reducing the need for manpower. In general, a power-assisted bicycle is a means of transportation designed to reduce the workload of the rider.
[0003] The frame mainly includes a main frame, side supports, rear forks, a middle support, a rear rack, a handlebar and other parts. The frame is similar to the skeleton of the human body. It is the mounting base of various assemblies of the power-assisted bicycle. It connects the motor and the body and other assemblies into an organic whole, and combines the various assemblies into a complete power-assisted bicycle. However, the existing rear rack of the frame cannot be adjusted according to the volume of the cargo, resulting in that it is inconvenient to bundle large cargo to the rear rack of the frame. For this reason, a shock-absorbing power-assisted bicycle frame is proposed. Utility Model Content

[0023] like Figures 1 to 4As shown, a shock-absorbing power-assisted bicycle frame includes a mounting frame 1, on which three fixing blocks 2 are fixedly mounted, and on the side wall of the mounting frame 1 three U-shaped rods 3 are fixedly mounted, and a telescopic rod 4 is movably mounted inside each U-shaped rod 3, and a mountain-shaped rod 5 is fixedly mounted on one end of each telescopic rod 4 away from the mounting frame 1, and a thread hole 6 is opened on the side wall of each U-shaped rod 3, and a plurality of thread holes 7 are opened on the side of each telescopic rod 4 close to the adjacent thread hole 6, and a bolt 8 is threadedly connected inside each thread hole 6, and two groups of support components 9 for supporting the mountain-shaped rod 5 are arranged on the mounting frame 1. It should be noted that when the cargo When the volume of the cargo is large, the mountain-shaped rod 5 can be pulled to the side away from the mounting frame 1 according to the volume of the cargo, and the mountain-shaped rod 5 then drives the three telescopic rods 4 to move respectively inside the three U-shaped rods 3 to the side away from the mounting frame 1 until the mountain-shaped rod 5 is moved to a suitable position and each thread hole 1 6 coincides with the adjacent thread hole 2 7, and then the tail end of each bolt 8 is threadedly connected to the inside of the adjacent thread hole 2 7, so that each telescopic rod 4 is fixed to the inside of the corresponding U-shaped rod 3. At this time, larger cargo can be placed on the frame composed of the U-shaped rod 3 and the telescopic rod 4, which solves the problem that the rear shelf of the existing power-assisted frame cannot be adjusted according to the volume of the cargo.
[0024] like Figure 1 , Figure 2 , Figure 4 As shown, the support assembly 9 includes a rectangular rod 901, and two rectangular rods 901 are fixedly installed on the side wall of the mounting frame 1.

[0027] like Figure 1 , Figure 2 , Figure 4 As shown, a cross bar 14 is fixedly installed between each two adjacent U-shaped bars 3, a slide groove 3 15 is opened on the side where each two adjacent telescopic bars 4 are close to each other, a cross bar 2 17 is arranged between each two adjacent telescopic bars 4, and movable blocks 16 are fixedly installed at both ends of each cross bar 2 17, and each movable block 16 is movably installed inside the adjacent slide groove 3 15. It should be noted that when the mountain-shaped bar 5 is moved to a suitable position, the two cross bars 2 17 are moved, and each cross bar 2 17 drives the two movable blocks 16 connected to it to slide respectively inside the corresponding slide groove 3 15, and the goods can be further supported by the cross bars 2 17 and the cross bar 1 14.
[0028] like Figure 1 , Figure 2 As shown, the two U-shaped rods 3 that are farthest from each other are fixedly installed with grooves 18 on the sides away from each other, and the two side walls of each telescopic rod 4 are fixedly installed with fixing rings 19, and the inner walls of each U-shaped rod 3 are symmetrical on both sides and are provided with fixing rings 20, and the internal hollow area of each fixing ring 20 passes through the top of the U-shaped rod 3. It should be noted that the grooves 18, the fixing rings 19 and the straps can be used to bundle the goods, and when the mountain-shaped rod 5 moves toward the side close to the mounting frame 1, each fixing ring 19 can reach the inside of the corresponding fixing ring 20.
[0029] In summary:
[0030] When the volume of the goods is large, the mountain-shaped rod 5 can be pulled to the side away from the mounting frame 1 according to the volume of the goods, and the mountain-shaped rod 5 then drives the three telescopic rods 4 to move respectively inside the three U-shaped rods 3 to the side away from the mounting frame 1 until the mountain-shaped rod 5 is moved to a suitable position and each thread hole 1 6 coincides with the adjacent thread hole 2 7, and then the tail end of each bolt 8 is threadedly connected to the inside of the adjacent thread hole 2 7, so that each telescopic rod 4 is fixed to the inside of the corresponding U-shaped rod 3. At this time, larger cargo can be placed on the frame composed of the U-shaped rod 3 and the telescopic rod 4, which solves the problem that the rear shelf of the existing power-assisted bicycle frame cannot be adjusted according to the volume of the cargo.
