Description

SPREAD FRONT-WHEEL DRIVE BIKES}

The present invention relates to a foldable bicycle, and more particularly, to an X-type foldable spread front wheel driven bicycle.

Bicycles are frequently used as a means of transportation between Seoul, Tokyo, New York, and large metropolitan trains between trains and transit stations. Bicycles need to be portable, eco-friendly, and lightweight for the intermediate connection of vehicles.

Rear-wheel-driven bicycles are not suitable for commuting due to the weight and clothing contamination of long chains and lubricating grease.

The folding rear-wheel drive bicycle has structural limitations when folded because of the chain.

In addition, the front wheel-driven folding bike has a problem in that continuous pedaling is difficult because the distance between the pedal located on the inner ring and the pedal located on the outer ring varies greatly from the saddle by handling that changes direction to one side during cornering.

1 to 8 are views for explaining the smart spread saddle of the X-type folding bike according to an embodiment of the present invention. 9 to 12 are views for explaining a spread current-driven bicycle according to another embodiment of the present invention.

1 to 8, the smart spread saddle of the X-type folding bicycle is a smart spread saddle of the X-type folding bicycle, and the X-type folding having a structure capable of providing a front wheel and a rear wheel on the rear side. A pipe-shaped support portion coupled to the bicycle body; A saddle cover installed on the support portion; And a pivoting part that is installed between the support part and the saddle cover and rotates the saddle around a rotating shaft extending to the left and right sides of the bicycle, and when the saddle cover is supported, installed on the front side and the rear side lower portion of the saddle cover, respectively. It has a saddle lower body having a resilient portion, the support portion is coupled with the bicycle body to rotate toward the front side about the axis of rotation of the front wheel during cornering of the bicycle, according to the rotation of the saddle lower body The rotation of the saddle bucker is limited to a certain range by the rotation part and the elastic part.

9 to 12, the optimized spread effective angle of the X-type folding bike (also referred to as the'X-folding bike') provides convenience in carrying, stable steering and straightness when riding, and transmits driving force to the driving wheels. This is an important factor, and in particular, it is a very important factor in view of the even distribution of the weight and the driving stability of the existing rear-wheel chain bicycle.

In order to withstand the load-bearing durability of the lightweight X-folding bicycle, the X-folding method is somewhat more durable and instability due to play due to the dynamics of the hinge point and the load, but the X-folding bicycle of this embodiment is maintained. While spreading, it is possible to simultaneously develop an effective angle and realize load-bearing durability.

For the dynamic driving durability of the X-folding bicycle, there are variables that can threaten driving due to various irregularities and debris on the road, so it is possible to respond effectively by differentiating the diameter of the front and rear wheels. . In this case, since the specific gravity of the on-road and off-road of the front wheel is large, it is preferable to make the diameter of the front wheel larger than the rear wheel.

In addition, despite the policy of encouraging the use of various commuting bicycles in the metropolitan area as a solidified commuter transportation means, there is a difficulty in storage due to the problem of clothes and work-related commuting and the volume problem of the folding bicycle during commuting, but the bicycle of this embodiment is a problem. Can be minimized.

In addition, the front-wheel-driven bicycle of the present embodiment solves the problem that it is possible to go straight on the existing bicycle, but continuous pedaling is impossible when steering the cornering. In other words, there is no problem when the pedal located on the front wheel goes straight, but when handling to change the direction to one side, the pedal located on the inner ring and the pedal located on the outer ring have different distances from the saddle. You can solve the problem.

In other words, when turning left with an existing front-wheel drive bicycle, the left pedal of the front wheel is located inside the wheel, so it is not a problem, but the right pedal is located outside the wheel, so that the right pedaling is impossible away from the driver. It was the limit of the bike. In this embodiment, such a drawback is solved by a front wheel and an optimized spread smart saddle.

When the folding bicycle is operated, it is possible to take a variety of angles (spread angles) to expand in an X-shape according to the user's body size, purpose of operation, and degree of fatigue.

In this regard, it is possible to provide an optimal spread angle by interlocking with a sensor installed in a saddle of a folding bicycle, Bluetooth, NFC built into a smartphone, and the like. In addition, a smart phone holder is installed on the folding bike of the present embodiment, and a communication module for communication with a smart phone may be installed on the bicycle body, saddle, or cradle.

As a communication module installed in the cradle, NFC (Near Field Communication) communication module or Bluetooth communication module for wireless communication with a smartphone may be installed. It may be configured to identify by transmitting the unique device IP of the smartphone to the control unit through communication with the smartphone.

Alternatively, the cradle is connected to the controller through a signal line, and may be configured to transmit data transmitted from the controller to the cradle through a communication module to a smartphone.

A pressure sensor may be adopted as a sensor installed on the saddle of the folding bike of this embodiment.

In daily metro commuting, not on leisure bicycles or on-road or off-road leisure leisure bicycles, customers can use the trunk of a car in a large metropolitan area where demands of eco-friendly transportation and demands (NEEDS) are intensified by reducing the operation of cars and using public transportation. It can be folded and folded easily to induce the use of bicycles for commuting between subway transit stations and automobiles and subways and companies, thereby saving energy in the city and reducing environmental protection fine dust.

The method of validating the optimum spread angle of the simple and lightweight bicycle method of the X-folding bicycle of this embodiment can be both smartphone interlocking and bicycle self-configuration, and through this, it is possible to supply eco-friendly commuting bicycles.

In addition, the bicycle of the present embodiment has an advantage that a unique design (possible to drive all wheels when an effective spread angle is applied) can also increase a user's personality or satisfaction.

Although described above with reference to preferred embodiments of the present invention, those skilled in the art variously modify and change the present invention without departing from the spirit and scope of the present invention as set forth in the claims below. You can understand that you can.
