DETAILED DESCRIPTION

[0026] The embodiments of the present application will be further described in detail below with reference to the drawings and examples. The following examples are used to illustrate the present application, but cannot be used to limit the scope of the present application.

[0027] Example one: as shown in the accompanying Figure 1 to the accompanying Figure 8 As shown: the present application provides a novel electric bicycle folder mechanism, including the body rear pipe 1, the body front pipe 2 and the locking assembly;

[0028] The first connecting frame 4 is fixed on the upper surface of the body rear pipe 1, and the second connecting shaft 10 is fixedly connected to the inner wall of the first connecting frame 4; the body front pipe 2 is hingedly connected to the body rear pipe 1.

[0029] The locking assembly comprises the opening and closing handle 5, the eccentric sleeve 501, the main hook 9, the auxiliary hook 14, the reset spring 15 and the auxiliary hook 16; the eccentric sleeve 501 is fixedly installed on the inner wall of the opening and closing handle 5 and eccentrically installed on the side of the second connecting shaft 10; the main hook 9 is rotatably installed on the side of the eccentric sleeve 501 through the torsional spring 902, and the side wall of the main hook 9 is provided with the embedded groove 901; the limiting edge 501a is fixedly connected to the side of the eccentric sleeve 501 and slidably arranged in the embedded groove 901; the limiting tooth 11 is arranged at one end of the main hook 9; the clamping table 12 is fixedly connected to the side of the second connecting sleeve 6; and the limiting tooth 11 is engaged with the clamping table 12.

[0030] The rotation groove 13 is penetrated through the handle body of the opening and closing handle 5, and the auxiliary hook 14 is rotatably installed on the inner wall of the rotation groove 13; the reset spring 15 is arranged between the auxiliary hook 14 and the rotation groove 13; the pressing part 1402 is arranged at the top end of the auxiliary hook 14, and the reset spring 15 is arranged between the bottom of the pressing part 1402 and the inner wall of the rotation groove 13; the clamping part 1401 is arranged at the bottom end of the auxiliary hook 14; and the auxiliary hook 16 is fixed on the upper surface of the body front pipe 2, and the clamping part 1401 is engaged with the auxiliary hook 16.

[0031] The first connecting sleeve 3 is arranged at one end of the rear tube 1, and the second connecting sleeve 6 is arranged at one end of the front tube 2.

[0032] When the opening and closing handle 5 is pressed, the eccentric sleeve 501 is driven to rotate, and the limiting rib 501a moves at this time. When the limiting rib 501a reaches the groove wall of the embedding groove 901, the limiting rib 501a moves with the handle, and drives the main hook 9 to displace, thereby changing the displacement stroke of the main hook 9 following the opening and closing handle 5, ensuring that the main hook 9 can be stably clamped with the clamping table 12. At the same time, the close cooperation between the auxiliary hook 14 and the auxiliary hook 16 forms an eccentric shaft tensioning and double locking structure, effectively eliminating the gap between the connecting part of the front tube 2 and the rear tube 1 of the electric bicycle, making the frame structure more stable during riding, reducing the shaking and swinging caused by the gap, and providing a more stable riding experience for the rider. Especially when driving at high speed or passing through bumpy roads, the advantage is more obvious; the elimination of the gap reduces the relative movement and collision between the parts, thereby significantly reducing the noise and vibration generated during riding. This not only improves the comfort of riding, but also reduces the wear and tear on vehicle parts caused by long-term vibration, prolonging the service life of the vehicle.

[0033] When the locking needs to be released, press the pressing part 1402 at the top end of the auxiliary hook 14 to overcome the elastic force of the reset spring 15, so that the clamping part 1401 is separated from the auxiliary hook 16, and the locking of the auxiliary hook 14 is released; when the opening and closing handle 5 is opened towards the rear tube 1, it is driven by the eccentric sleeve 501, and the main hook 9 rotates towards the rear tube 1 and separates from the bite part of the front tube 2.

[0034] As can be seen from the above, when it is necessary to unfold the electric bicycle from the folded state to the rideable state, the front tube 2 and the rear tube 1 are unfolded through the hinged structure of the first connecting sleeve 3 and the first connecting shaft 7. The cooperation of the first connecting sleeve 3 and the first connecting shaft 7 enables the front tube 2 and the rear tube 1 to accurately reach the predetermined relative position; the operator holds the opening and closing handle 5 and rotates it. Since the opening and closing handle 5 is eccentrically installed on the side of the second connecting shaft 10, rotating the opening and closing handle 5 will produce an eccentric tensioning effect. This tensioning force will be transmitted to the entire connecting structure along the second connecting shaft 10, so that the front tube 2 and the rear tube 1 begin to approach each other, and the possible gap is initially reduced.

[0035] With the rotation of the opening and closing handle 5, the main hook claw 9 also rotates, and the limiting teeth 11 and the clamping table 12 gradually engage, playing a role in limiting the front pipe 2 and the rear pipe 1 of the vehicle body in the horizontal direction, preventing them from shaking left and right, and further tightening the front pipe 2 and the rear pipe 1 of the vehicle body during the engagement process due to the eccentric characteristics of the main hook claw 9, making the connection between them more tight, and further eliminating the gap in the horizontal direction.

[0036] At the same time of the rotation of the opening and closing handle 5, the bottom end of the clamping part 1401 of the auxiliary hook claw 14 will gradually approach and be clamped with the auxiliary hook claw 16 fixed on the upper surface of the front pipe 2 of the vehicle body under the action of the reset spring 15. When the clamping part 1401 is completely clamped with the auxiliary hook claw 16, the front pipe 2 and the rear pipe 1 of the vehicle body are firmly locked in the vertical direction. During this clamping process, due to the close fit between the auxiliary hook claw 14 and the auxiliary hook claw 16 and the elastic force of the reset spring 15, the front pipe 2 and the rear pipe 1 of the vehicle body are further tightened, eliminating the gap in the vertical direction. Finally, through the double locking action of the main hook claw 9 and the auxiliary hook claw 14, the gap at the connection part between the front pipe 2 and the rear pipe 1 of the vehicle body is effectively eliminated, ensuring the stability and reliability of the overall structure of the vehicle.

[0037] When it is necessary to fold the electric bicycle, the operator first presses the pressing part 1402 at the top end of the auxiliary hook claw 14, overcomes the elastic force of the reset spring 15, separates the clamping part 1401 from the auxiliary hook claw 16, releases the locking of the auxiliary hook claw 14, and then reversely rotates the opening and closing handle 5 to separate the limiting teeth 11 on the main hook claw 9 from the clamping table 12, releasing the locking of the main hook claw 9.

[0038] At this time, the locking between the front pipe 2 and the rear pipe 1 of the vehicle body has been completely released, and through the hinged structure of the first connecting sleeve 3 and the first connecting shaft 7, the front pipe 2 and the rear pipe 1 of the vehicle body can be rotated relative to each other, realizing the folding of the electric bicycle. During the folding process, the connection part between the front pipe 2 and the rear pipe 1 of the vehicle body will return to a state where there may be a certain gap, but when it is unfolded and locked next time, the above process of eliminating the gap will be repeated, ensuring that the connection part is tight and gapless every time it is used.

[0039] Example two: on the basis of example one, the rear pipe 1 and the front pipe 2 of the vehicle body are both hollow pipe structures, and the inner cavities of the rear pipe 1 and the front pipe 2 form battery compartments.

[0040] As can be seen from the above, the internal space of the rear pipe 1 and the front pipe 2 of the vehicle body is fully utilized, avoiding the space occupied by the additional battery compartment, making the overall structure of the electric bicycle more compact, and being conducive to the storage and carrying after folding.
