DETAILED DESCRIPTION

[0024] The following is a detailed description of a lightweight and high-strength bicycle folding device provided by the utility model in combination with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art may also adopt other alternatives to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments, and are not intended to specifically limit the utility model.

[0025] like Figure 1 and Figure 4 As shown, an embodiment of the utility model provides a lightweight and high-strength bicycle folding device, comprising: an upper body 1; a lower body 2, movably arranged at the bottom of the upper body 1; a buffer part 13, respectively arranged in the upper body 1 and the lower body 2, for reducing vibration when the bicycle folding device is used, and the buffer part 13 comprises: a plurality of first deformation bars 131, arranged on one side of the inner cavity of the upper body 1, for absorbing the force; a plurality of second deformation bars 133, arranged on the other side of the inner cavity of the upper body 1, and arranged in an opposite and staggered manner to the first deformation bars 131, for increasing the stability of the folding device; a plurality of supporting deformation ribs 132, arranged between the first deformation bars 131 and the second deformation bars 133, and the supporting deformation ribs 132 are curved, for transferring the force applied to the folding device.

[0026] By providing the buffer portion 13, the first deformation bar 131 and the second deformation bar 133 are arranged in a staggered corresponding manner. When the folding device is subjected to the vibration impact from the bumpy road section, the first deformation bar 131 and the second deformation bar 133 can undergo a slight deformation, absorb and dissipate the vibration energy, play a role in vibration reduction and buffering, reduce the impact of vibration on the folding device and the entire vehicle, and improve riding comfort; by providing the supporting deformation rib 132, the first deformation bar 131 and the second deformation bar 133 are effectively connected to form an overall shock absorbing system, which not only undertakes the function of transmitting vibration energy and maintaining the relative position stability between the deformation bars, but also provides the necessary supporting force to prevent the deformation bars from excessively deforming when absorbing vibration.

[0027] like Figure 4 As shown, the distances between the first deformation strips 131 and the second deformation strips 133 are the same.

[0028] By setting the first deformation bar 131 and the second deformation bar 133, when the vibration is transmitted to the first deformation bar 131, the second deformation bar 133 and the supporting deformation rib 132, they will undergo a slight deformation. This deformation is equivalent to storing the vibration energy and converting it into elastic potential energy. The elastic potential energy is proportional to the degree of deformation. As the vibration continues, the elastic potential energy will accumulate inside the first deformation bar 131, the second deformation bar 133 and the supporting deformation rib 132.

[0029] like Figure 1 and Figure 3 As shown, it also includes: a knob 3, which is rotatably arranged on the lower body 2; a rotating clamping strip 11, which is rotatably arranged in the lower body 2; and a clamping column 12, which is arranged in the upper body 1. By setting the knob 3, it is convenient for personnel to operate without providing a large operating force.

[0030] like Figure 1 and Figure 3 As shown, the rotating clamping strip 11 is connected to the knob 3 through a connecting rod, and a clamping slot is provided on one side of the rotating clamping strip 11. By setting the rotating clamping strip 11, the rotating clamping strip 11 can play an auxiliary fixing role for the folding device, and through double fixing, the folding device is prevented from being easily opened.

[0031] like Figure 2 As shown, it also includes: a support plate 4, which is arranged in the upper body 1; a tension spring 5, which is arranged at the bottom of the support plate 4; an L-shaped rod 7, which is movably arranged in the upper body 1, a connecting block 6, which is arranged on the L-shaped rod 7, and the top of the connecting block 6 is connected to the tension spring 5; a semicircular block 8, which is arranged at the bottom of the L-shaped rod 7 and is located in the lower body 2.

[0032] By setting the tension spring 5, the tension spring 5 and the L-shaped rod 7 are fixedly connected via the connecting block 6, so that the L-shaped rod 7 moves downward, driving the tension spring 5 to deform, thereby providing a pulling force for the L-shaped rod 7 to reset.

[0033] like Figure 2 As shown, the surface of the upper body 1 is provided with a moving groove, and one side of the L-shaped rod 7 passes through the moving groove. By providing the moving groove, one side of the L-shaped rod 7 passes through the moving groove, which is convenient for personnel to move the L-shaped rod 7, thereby performing a fixing operation.

[0034] like Figure 2 As shown, it also includes: a plurality of elastic rods 10, which are arranged in the lower body 2, and one side of the elastic rod 10 passes through the lower body 2; a semi-arc block 9, which is arranged on the elastic rod 10 and located in the lower body 2.

[0035] By setting the semi-arc block 9, the L-shaped rod 7 drives the semicircular block 8 to move downward, and the arc surface of the semicircular block 8 contacts the arc surface of the semi-arc block 9, thereby pushing the semi-arc block 9 to move outward, driving the elastic rod 10 to move outward, so that the semicircular block 8 is located at the bottom of the semi-arc block 9, and the bottom of the semi-arc block 9 is flat, so that the semicircular block 8 is fixed, thereby fixing the folding device.

[0036] like Figure 1 As shown, the upper body 1 and the lower body 2 are respectively made of one of carbon fiber composite materials, high-grade aluminum alloy and titanium alloy.

[0037] By setting up carbon fiber composite materials, it has extremely high tensile strength and bending strength while being very light. By adjusting the type, number of layers, direction of carbon fiber and the formula of the resin system, the rigidity, shock absorption and stability of the frame can be precisely controlled to achieve customized design for different riding needs; by setting up high-grade aluminum alloy, it has low cost, good corrosion resistance and light weight. After heat treatment, it can provide higher strength and hardness while maintaining a certain elasticity, and is suitable for various riding conditions; by setting up titanium alloy, it has excellent strength, corrosion resistance and excellent energy absorption characteristics. The titanium alloy bicycle folding device is extremely durable and has a long lifespan and can withstand harsh riding environments.

[0038] The technical solution provided by the utility model is that the upper body 1 and the lower body 2 are installed at the center of the frame. When the bicycle needs to be folded, the knob 3 is turned to drive the rotating clamping bar 11 to rotate, so that the rotating clamping bar 11 is separated from the clamping column 12, and then the elastic rod 10 is stretched outward to make the semi-arc clamping block 9 separate from the semi-circular block 8, and the L-shaped rod 7 and the semi-circular block 8 are driven to move upward by stretching the spring 5 to complete the folding of the bicycle; when the bicycle is ridden on a bumpy road section, the vibration generated is transmitted to the upper body 1 and the lower body 2, and its force is absorbed by the first deformation bar 131, and with the cooperation of the supporting deformation rib 132 and the second deformation bar 133, the force generated by the vibration is transferred to avoid affecting the internal locking mechanism.

[0039] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
