Description

Technical field:

[0001] The invention belongs to a bicycle and an electric bicycle driven by human pedaling. Background technology:

[0002] Bicycles that use a chain driven by pedals to drive the rear wheel are a common means of transportation around the world. Long-distance human pedaling is tiring, so electric bicycles that use battery power to drive hub motors installed on wheels are developed. It costs a lot of money to buy and replace new batteries, and daily charging is inconvenient. There is also the environmental protection issue of handling discarded batteries. Conventional bicycle transmissions, such as those of Japan's Shimano, also need to further improve their performance. Summary of the invention:

[0003] The purpose of the present invention is to overcome the above-mentioned defects of the prior art and provide a new type of electric-assisted bicycle which obtains electricity by human pedaling force and does not need to be equipped with a battery.

[0004] The technical solution for achieving the purpose of the present invention is as follows:

[0005] The single-generator basic type of the electric-assisted bicycle of the present invention, which does not require a battery, comprises left and right pedals pedaled by human power and a speed-increasing mechanism driven by the pedaling force, including a generator shaft and a rear wheel shaft driven by gears and / or a belt pulley; the power obtained by the generator shaft rotating at a higher speed due to the pedaling force of the human power is used to drive a hub motor installed on the front wheel or rear wheel shaft of the bicycle; the speed-increasing mechanism has two sets of speed-increasing gears, one of which comprises a sprocket located beside the right pedal on the left and right pedal shafts installed in the through hole in the generator shaft, and a small-diameter gear on the gear transmission shaft above the left and right pedal shafts, and a left and right gear on each of the two end positions of the shaft. The hand crank handle; a large-diameter pulley or gear coaxial with the small-diameter gear is fixedly installed on the transmission shaft, which drives the small-diameter pulley or gear installed on the right side of the generator shaft below with a belt transmission, which rotates at the same speed as the generator shaft, and another set of speed-increasing mechanisms is installed at the left proximal end of the generator shaft. It is a large-diameter pulley or gear fixedly installed at the left proximal end of the generator shaft, on the inner side of the left pedal, which rotates coaxially and at the same speed as the generator shaft, and is driven to the small-diameter gear on the rear wheel shaft by a belt, thereby driving the rear wheel to rotate at a faster speed; its dual-generator type includes the basic type with a belt inside the generator shaft The shafts of the left and right pedals with bearings are the inner shafts, and the shaft of the rear wheel is also set as a generator shaft with speed increase and an inner shaft with bearings inside its shaft. The characteristic is that the chain of the large-diameter sprocket driven by the pedals on the right side of the bicycle simultaneously drives the small-diameter gear on the horizontal transmission shaft above and in front of it and the small-diameter gear and large-diameter belt pulley arranged in parallel on the inner shaft of the rear wheel. The large-diameter belt pulley drives the small-diameter belt pulley of the generator shaft forward with a belt to increase the speed of rotation of the generator shaft. At this time, the large-diameter belt pulley or sprocket fixedly installed on the other side of the generator drives the small-diameter belt pulley or gear of the rear wheel shaft backward with a belt or sprocket to increase the speed of rotation of the rear wheel shaft The rear wheel shaft also serves as a generator shaft, and is equipped with all the components of the generator to generate electricity to form a second generator. The electricity generated by the two generators is used to drive the hub motor installed on the front wheel to form an electric power-assisted bicycle; the role of the horizontal transmission shaft and its small-diameter gear at the front and upper part of the generator is to form the hand-cranked handlebars at both ends of the shaft to play a power-assisted rotation role; the front body frame of the bicycle has a vertical cylindrical bracket with a slightly backward tilted upper half on each front wheel, and the bracket has a cylindrical front wheel bracket that can rotate left and right. The upper part of the front wheel bracket is a horizontally placed front wheel steering handlebar and its left and right handles, and the lower part of the front wheel bracket is a front wheel double front fork;The cylindrical front wheel bracket which can rotate left and right has a contact block structure extending backward as a secondary device of the linear motor. It is slightly sandwiched by two arc-shaped components with the structural function of the primary device of the linear motor arranged opposite to its upper and lower surfaces, and the contact block type secondary device can move back and forth to the left, middle or right in the arc-shaped guide rail. The contact block of the front wheel bracket is electrically driven by the double-sided arc-shaped linear motor primary device to move, thereby completing the steering of the front wheel including the single front wheel of all bicycles and each front double wheel of a four-wheeled vehicle; each front wheel of the left and right double front wheels of the four-wheeled vehicle adopts a single inner front wheel bracket installed inside the front of the vehicle, and the front wheel bracket and its linear motor secondary and primary devices are arranged at a position above the front wheel or at a position inside the vehicle. When the front wheel bracket is located above the front wheel, the arc-shaped linear motor primary and secondary device mode is applicable. When it is located at the inside of the front wheel, the applicable linear motor primary and secondary device mode is linear, and the secondary device is installed on a horizontal transverse bracket fixedly extended from the front wheel axis. One of the basic ways to steer the front wheel of a bicycle is to directly turn the front wheel left and right steering handlebars by hand to steer the front wheel.

[0006] Graphic description:

[0007] The accompanying drawing is a three-dimensional side view schematic diagram of the basic main structure of an electric power-assisted bicycle with a generator shaft and a rear wheel shaft driven by human speed increase;

[0008] Attached Figure 1"1" here is the central crankshaft of the left and right pedals of the bicycle; "2" is the bearing of "1"; "3" is the shaft of the generator; "4" is the bearing of the shaft of the generator, and "5" is the generator; "6" is the rear body frame of the rear wheel; "7" is the front body frame of the bicycle, which supports the generator "5" and the crankshaft "1" fixedly mounted in the internal through hole of the generator shaft "3"; the bearing "2" is located between "1" and "3"; a large-diameter toothed disc, such as 53 teeth, 50 teeth, or 48 teeth, is fixedly mounted at the end of the shaft "1" close to the right pedal, which drives the upper small-diameter gear fixedly mounted on the horizontal transmission shaft "11" with a chain, and a large-diameter belt pulley, such as 53 teeth, 50 teeth, or 48 teeth, is also fixedly mounted on the transmission shaft "11" on the inner side of the small gear, which drives the small-diameter belt pulley fixedly mounted on the right end of the generator shaft below in a belt transmission manner. A large-diameter belt pulley or gear with the same gear ratio is fixedly installed at the left end of the generator shaft near the left pedal, and the belt drives the small-diameter belt pulley or gear fixedly installed on the rear wheel shaft of the rear wheel "8" backwards to drive the rear wheel shaft to rotate faster; "9" is a seat cushion for the cyclist; "10" is a bicycle chain, which is driven by the rotation of a sprocket with 53 teeth, 50 teeth or 48 teeth installed on the shaft "1"; "11" is a transmission shaft of the 16-tooth gear above driven by the chain "10"; "12" is a small-diameter belt pulley or gear transmission belt driven by the large-diameter belt pulley or gear fixedly installed on the shaft "11" to the right end of the generator shaft installed below, thereby driving the generator shaft "3" to rotate to generate electricity, and the generated electricity is used to drive the rear wheel hub motor; the front wheel bracket and the left and right double front forks are installed on the wheel shaft of the front wheel "13"; the front wheel steering handle is built-in with its cylindrical bracket and vertically placed in a cylindrical bracket of the front body of the bicycle.

[0009] Effect:

[0010] The interaction between the various components is that, according to the gear ratio arrangement mentioned above, when the 48-tooth sprocket on the central crank shaft of the pedal rotates one circle, for example, the 16-tooth transmission gear on the upper transmission shaft rotates three circles through the chain transmission, and the large-diameter belt pulley on the same axis also rotates three circles. At the same time, each rotation of the sprocket drives the small-diameter generator shaft at the lower right side of the bicycle to rotate at least three circles through the belt transmission. At the same time, the large-diameter gear disk installed near the left end of the generator shaft is transmitted to the small-diameter belt pulley or gear on the rear wheel shaft through a belt or gear, thereby increasing the speed and driving the bicycle. The rear wheel of the bicycle obtains the above-mentioned 1:3 to 1:4.55-4.81 gear ratio speed-up rotation effect and moves forward; the power generated by the generator drives the hub motor of the rear wheel to make the rear wheel move forward, and the hand-cranked force at both ends of the upper transmission shaft is used to assist the transmission shaft to rotate. The combined force of these three forces enables this bicycle to have the forward power of the electric-driven rear wheel hub motor without being equipped with a battery; when the cyclist increases the downward pedaling force with his weight, a labor-saving bicycle movement effect under the action of gravity will be generated. Example:

[0011] The bicycle can also be equipped with various conventional high-efficiency batteries, including hydrogen batteries, and a manual front wheel steering controller with a built-in control chip and a wire remote control. The right hand finger can hold the hand cranks at both ends of the upper transmission shaft while pressing the rocker of the controller that can be turned to the left or right. In this way, the hand crank can be easily rotated with the right hand while the rocker can be moved to the left, center or right with the finger, thereby further driving the cylindrical linear motor to drive the front wheel bracket to maintain the center straight forward or steering state, thereby realizing the direction control of the front wheel. A basic method of front wheel steering is to turn the hand crank with the right hand and move the rocker to the left, center or right with the finger. The method is to directly hold and rotate the left and right conventional handlebars for horizontal steering on the left and right front fork brackets of the front wheel with hands to achieve front wheel steering; the front wheel direction control method of the present invention is also applicable to the steering of the single front wheel of all two-wheeled bicycles and the double front wheels of four-wheeled vehicles, especially for four-wheeled vehicles, the differential steering method of the left and right wheels can also be implemented to further enhance the directional control performance of the front wheel steering; the dual-generator electric-assisted bicycle of the present invention can also be installed without the horizontally placed transmission shaft located above the front of the generator and the small-diameter gears on the shaft and the left and right hand crank handles, and the structure thus constructed is still a front and rear dual-generator type.
