Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1-5 A load-carrying electric bicycle frame with an anti-collision mechanism comprises a bicycle frame 1, an oblique support column 2 is arranged at one end of the top of the bicycle frame 1, a plurality of transverse arc support columns 3 are arranged on both sides of the oblique support column 2, a vertical support column 4 is fixed on the side of the transverse arc support column 3 away from the oblique support column 2, a detachable U-shaped retaining tube 5 is arranged on the side of the vertical support column 4 away from the oblique support column 2, and a disassembly mechanism for disassembling the U-shaped retaining tube 5 is arranged inside the vertical support column 4;

[0024] An arc-shaped baffle plate 6 for protection is arranged at one end of the oblique support column 2 close to the bicycle frame 1, and a plurality of buffer mechanisms are arranged between the arc-shaped baffle plate 6 and the transverse arc-shaped support column 3;

[0025] The buffer mechanism includes two rectangular fixed blocks 7, the two rectangular fixed blocks 7 are close to one side of the arc baffle 6 and are fixedly connected to the arc baffle 6, a transverse light rod 8 is fixed between the two rectangular fixed blocks 7, and two rectangular moving blocks 9 are slidably connected to the outer side of the transverse light rod 8, and the rectangular moving block 9 is rotatably connected to an oblique rotating column 10 at one end close to the transverse arc support column 3, and a rectangular connecting block 11 is rotatably connected between the two oblique rotating columns 10 through a pin shaft, and the rectangular connecting block 11 is close to one end of the transverse arc support column 3 and is fixedly connected to the transverse arc support column 3;

[0026] A first rigid spring 12 is provided between the rectangular fixed block 7 and the rectangular moving block 9 and between the two rectangular moving blocks 9, and the first rigid spring 12 is located outside the transverse light rod 8;

[0027] When splashes hit the arc baffle 6, the two rectangular moving blocks 9 can slide outside the transverse light rod 8. The sliding of the rectangular moving blocks 9 causes the first rigid spring 12 to deform under force, thereby buffering the impact of the splashes, so that the arc baffle 6 can better protect the driver's legs.

[0028] A circular through hole is provided inside the rectangular moving block 9, and the transverse light rod 8 is located inside the circular through hole and is slidably connected with the rectangular moving block 9 through the circular through hole. The setting of the circular through hole enables the rectangular moving block 9 to slide outside the transverse light rod 8;

[0029] The rectangular moving block 9 and the oblique rotating column 10 as well as the oblique rotating column 10 and the rectangular connecting block 11 are all rotatably connected via a pin shaft. By setting the pin shaft, the rectangular moving block 9 and the oblique rotating column 10 as well as the oblique rotating column 10 and the rectangular connecting block 11 can be better protected;

[0030] The disassembly mechanism includes a circular pull ball 13, a circular pull ball 13 is arranged on the top of the vertical support column 4, a vertical sliding column 14 is fixed at the bottom of the circular pull ball 13 and located inside the vertical support column 4, the vertical sliding column 14 penetrates the inside of the vertical support column 4 and is slidably connected with the vertical support column 4, and a second rigid spring 15 is arranged between the circular pull ball 13 and the vertical support column 4 and located outside the vertical sliding column 14;

[0031] A circular limiting hole is provided inside the U-shaped retaining tube 5, and the vertical support column 4 and the vertical sliding column 14 are fitted through the circular limiting hole. Through the setting of the circular limiting hole, the vertical sliding column 14 can be inserted into the U-shaped retaining tube 5, thereby limiting the movement of the U-shaped retaining tube 5 inside the vertical support column 4;

[0032] The circular pull ball 13 is pulled away from the vertical support column 4. The movement of the circular pull ball 13 enables the vertical sliding column 14 to move out of the U-shaped retaining tube 5, so that the U-shaped retaining tube 5 can be disassembled. During this process, the second rigid spring 15 is in a stressed and extended state.

[0033] By setting the arc-shaped baffle plate 6, splashes can be blocked, and by setting the buffer mechanism, when splashes hit the arc-shaped baffle plate 6, buffering performance can be provided for the arc-shaped baffle plate 6, thereby better protecting the driver's legs, reducing injuries during collisions, and improving the driver's safety. In addition, by setting the disassembly mechanism, the U-shaped baffle tube 5 can be disassembled, which facilitates the maintenance and replacement of the U-shaped baffle tube 5 and extends the service life of the U-shaped baffle tube 5.

[0034] Working principle: When splashes hit the arc baffle 6, the two rectangular moving blocks 9 can slide on the outside of the transverse light rod 8. The sliding of the rectangular moving blocks 9 causes the first rigid spring 12 to deform under force, thereby buffering the impact of the splashes, so that the arc baffle 6 can better protect the driver's legs;

[0035] The circular pull ball 13 is pulled away from the vertical support column 4. The movement of the circular pull ball 13 enables the vertical sliding column 14 to move out of the U-shaped retaining tube 5, so that the U-shaped retaining tube 5 can be disassembled. During this process, the second rigid spring 15 is in a stressed and extended state.
