Description

The present invention relates to a two-wheeled or three-wheeled motorcycle that travels using an electric motor as a main power, and more particularly to a motorcycle frame that is driven over a range other than a scooter. Is a frame that is completely different in function and configuration. That is a completely new technical field.

In recent years, motors with high energy efficiency have been developed, and with increasing awareness of the environment and energy conservation, motorized vehicles have become more electrified, and electric vehicles have reached a practical level and have been commercialized by multiple manufacturers. ing.
However, in the world of two-wheeled vehicles including three wheels, it is extremely difficult to install a heavy battery, so it is exclusively based on a so-called scooter type that operates with the knees aligned, under the footrest or under the seat. The configuration with a heavy battery is the mainstream. However, the scooter type is highly convenient for short-distance commuting and shopping, but lacks the pleasure of maneuvering and low level of attention inherent in motorcycles.
Therefore, in the present invention, it is assumed that a so-called sports-type motorcycle that runs across the road without being bound by existing concepts and configurations is driven by an electric motor, but a motorcycle that is driven by an engine is simply a motor. Even if it is replaced with, sufficient function cannot be demonstrated. This is because there is basically no background technology, and the configuration of an engine-type motorcycle having a different function or configuration or a bicycle without a power source is not helpful at all.
Further, when making a motorcycle frame, the most important point in terms of function is to support the weight of the engine and to support the impact load from the wheels applied to the front wheel mounting portion and the rear wheel mounting portion. However, with existing engine-type motorcycles, the mounting position of the engine and the positional relationship between the front and rear wheels cannot be changed, so that any manufacturer can make a move away from the double cradle type or diamond type frame form. Can not.
In addition, the existing business operators only make motorcycles that use engines, and there is no person skilled in the art regarding the technology of running sports-type motorcycles that straddle with electric motors. In motors, functions, characteristics, handling methods, fuel, safety, vibrations, etc. are all different, so it is possible to produce an engine-type motorcycle. It is absolutely impossible to produce, and because it is a completely new vehicle, there is no basis or track record for producing it.
First of all, in the current situation where the required functions required for an electric motorcycle are not clear, it is impossible to develop an electric motorcycle, and in fact, there is no market record.

With the existing technology, only a scooter type two-wheeled vehicle can be made, and there was a problem with the motor performance, which is a pleasure inherent to motorcycles. Therefore, there is a demand for a technology that can be electrically driven even in a so-called sports type motorcycle that is driven across a saddle type frame.
However, if you try to match the position of the center of gravity to the same position as the engine type motorcycle to ensure exercise performance, there is usually no feature just by installing the battery in the position where the fuel tank or engine is installed As a result, it becomes a simple and obsolete vehicle derived from an engine type motorcycle, and a good impression from the market cannot be obtained, and an electric motor type motorcycle that has a promising future power source cannot be widely used. In addition, following the form of an engine-type motorcycle in an electric motorcycle with extremely low vibration for the purpose of saving energy is wasteful, meaningless, and an increase in manufacturing cost is a fatal defect. .
Therefore, the existing concept of the frame for mounting the engine is completely wiped out, and it is specially designed for electric motorcycles. It is novel in appearance, can be identified instantly, and has advanced functions such as strength and loadability. Satisfactory car body construction is needed. In particular, with respect to vibration countermeasures, in the case of an engine type, the resonance point changes in accordance with the number of revolutions per minute, so that there is a problem that only specific parts resonate and generate sound only at a particular number of revolutions. For this reason, a number of reinforcements are applied to each part, resulting in a complicated and expensive form, which is a cause of hindering the entry of SMEs.
Therefore, the frame form for gasoline motorcycles is not referred to at all, and a highly promising vehicle form specialized for electric motorcycles is demanded from the market.
Specifically, it is an object of the present invention to provide an electric-dedicated vehicle body configuration that satisfies all the following conditions, which is absolutely impossible with existing engine-type motorcycles.
1. Unlike engines and gasoline tanks, the most effective use of the features of batteries that can be divided and installed in multiple locations is made possible by making the structure impossible to apply to gasoline motorcycles. Have distinguishable features.
2. A battery with a substantially rectangular parallelepiped shape can be safely mounted without being damaged even if it falls.
3. The main frame must be as simple as possible in order to widely spread electric motorcycles, and it can be manufactured at low cost and without special equipment. Specifically, a high-precision frame can be manufactured with equipment equivalent to a surface plate and a welding machine.
4. A frame that can be disassembled to reduce costs during storage and distribution, and can be assembled by simple bolt fastening work without using special equipment during assembly. Also, the wheelbase and battery capacity can be changed according to driving conditions.
5. It must be easy to replace, add or reduce heavy batteries.
6, Easy to manufacture, with a simple structure, it must support all front wheels, rear wheels, motors, batteries, seating seats, suspensions, and lighting equipment to withstand the load during driving.
7. The torsional rigidity required for the frame should be easy to understand, and can be easily secured by simple manual calculation without complicated structural analysis. In other words, it must be a simple structure that can calculate torsional stiffness and bending stiffness using the formulas described in the textbook of material mechanics at the University of Science and Technology.
8. Each company will be able to easily demonstrate its unique features in the vehicle configuration and appearance design.
9. To be able to cope with future improvements in the functions and performance of motors and batteries. In other words, it is possible to easily replace and update parts according to the changing times.
10. Incorporate technologies and configurations that extend the cruising range as much as possible, such as reducing air resistance.
11. It should be configured so that an optimum steering device can be introduced in accordance with the frame form obtained by electrification.

The rear wheel attachment part and the front wheel attachment part are connected by a frame with the shortest distance, and the cross-sectional shape of the frame is a shape with high torsional rigidity such as an H shape or a shape in which a box is connected. Thus, while ensuring the strength and torsional rigidity required for the frame, it is possible to secure the loadability of a heavy and large-volume battery.
In addition, a steering device that operates the grip in the front-rear direction can be adopted by taking advantage of the feature that the vehicle width can be extremely narrow according to the battery mounting method.
Specifically, the configuration detailed in any one of claims 1 to 10 is adopted.

According to the present invention, the portion for receiving the load from the rear wheel and the portion for receiving the load from the front wheel are connected by the frame having high rigidity, and a large number of batteries can be mounted. Can be said to be optimal. Further, since the engine type motorcycle has an engine that cannot be divided or moved between the front wheel mounting portion and the rear wheel mounting portion, the frame of the present invention can never be employed. That is, it is possible to provide a novel electric motorcycle that can be instantly distinguished from an engine type motorcycle.
Furthermore, since the main frame of the present invention can use a steel having a simple cross-sectional shape or a cylindrical member having a simple square cross-section, no special production equipment is required, and necessary dimensional accuracy can be easily secured. As a result, SMEs can enter the electric motorcycle market and contribute greatly to the development of the industry.

It is the best mode to employ any one of the configurations detailed in claims 1 to 10.
Specifically, the front wheel mounting portion and the rear wheel mounting portion are connected by a main frame made of steel having a constant cross-sectional shape resistant to twisting, and a heavy battery is mounted on the main frame. In addition, the main frame may be configured by connecting cylindrical members having a square cross section in the horizontal direction.

The embodiments of the present invention are as described in detail in claims 1 to 10, and by adopting any one of them, all of the above-mentioned problems can be solved.

FIG. 1 is a schematic view showing an example of an electric motorcycle according to the present invention, and represents a left side view of a vehicle. The front wheel 3 is an axle 8 and is attached to a front fork 7 which is a shock absorber that expands and contracts. 7 is slidably mounted on a head pipe 4 serving as a steering shaft, sits on a seating seat 10, and puts a foot on a footrest 22. The placed driver can steer the motorcycle with the handle 6.
Reference numeral 12 denotes a rear frame for supporting the driving shaft 13 of the drive motor 13 and the swing arm 15 for the rear wheel. The rear wheel 20 is attached to 15 at the axle 19 so as to be vertically movable, and the sprocket 17 attached to 13 drives the sprocket 18 attached to 20 via the chain 16.

Here, it is only necessary to connect the vicinity of 14 that is the swing center of the swing arm for the rear wheel and the vicinity of 4 that is the steering shaft with a strong main frame and a battery that can be mounted.
Therefore, in FIG. 1, as an example, the main pipe 1 having a reverse T-shaped cross section and made of steel mold connects the vicinity of the rear frame 12 to the head pipe 4. With this configuration, if the plate 9 for mounting the battery is welded to one side, the battery 2 can be easily mounted, and the position of the center of gravity of the motorcycle can be changed by changing the battery mounting position. It becomes possible to adjust the maneuverability and stability as a vehicle. Reference numeral 5 denotes a headlight, and 11 denotes a taillight.

FIG. 2 is a schematic view of the frame shown in FIG. 1 as viewed from above, and shows a configuration in which a subframe is provided. The battery 2 is mounted on the left and right sides of the frame 1 having an inverted T-shaped cross section. However, in the configuration of FIG. 1, when the motorcycle falls down, the battery is damaged and dangerous. Therefore, a rod-like or plate-like subframe 23 is installed on the frame 1 to protect the battery. In order to facilitate the attachment / detachment / replacement of the battery, the intermediate portion 24 of the sub-frame 23 is detachably attached with a bolt, or one end of the sub-frame 24 is fixed with a hinge so as to be freely opened and closed.

FIG. 3 is a schematic diagram showing an example in which the main frame is different from the configuration shown in FIG. A plurality of cylindrical members 25 having a rectangular cross-sectional shape are connected, and the vicinity of 14 of 12 and 4 are connected similarly to the configuration of FIG. According to this configuration, the battery can be safely stored inside each cylindrical member, and since the battery can be detached from the left and right side directions, an optimal frame for an electric motorcycle can be provided. . In addition, because of its extremely simple shape, it can be easily manufactured by small and medium-sized enterprises that do not have special equipment, and the rigidity can be easily changed by changing the thickness of the structure in which a partition plate is provided inside the cylindrical member. , Can greatly contribute to the development of the electric motorcycle industry. The above is the embodiment of the present invention described in claim 1.
Even if the front wheel is equipped with a swing arm similar to 15 and a front wheel shaft is installed at the front end of the arm via a steerable bearing, the so-called hub steering type configuration has a vicinity of 14 on the rear wheel side. And the vicinity of the swing center of the swing arm on the front wheel side may be connected by the main frame of the above-described form.

According to the present invention, since the main structural part of the frame has a very simple form, any material can be used. Depending on the required strength, various materials can be used, and by using an assembly method with bolts or the like, it is possible to combine the most suitable materials depending on the use site. The above is the embodiment of the present invention described in claim 2.

A large amount of electric power is required to drive the motor for traveling, and the battery generates heat as it is charged and discharged. Therefore, if the flat part of the substantially rectangular parallelepiped battery is brought into close contact with the flat part of the frame of the present invention, the frame itself becomes a heat radiating plate, and heat can be radiated without using a special device. Since engine-type motorcycles generate noise due to resonance, a flat frame cannot be adopted. Therefore, the form of the main frame of the present invention can be said to be an optimum shape specialized for an electric motorcycle. If the plate cannot be in close contact, heat can be dissipated by attaching a plate to the frame as a base on which the battery is placed. The above is the embodiment of the present invention described in claim 3.

As a motorcycle, the battery is not visible from the outside, and the impression is poor. Accordingly, a subframe having a bumper function may be used to attach a cover formed of resin or the like to form a design surface. In order to prevent resonance due to vibration in the engine type motorcycle, there are very fine restrictions on the form, shape and mounting method of the cover, but the electric motorcycle of the present invention is not particularly restricted by vibration, so the design The degree of freedom has increased dramatically, allowing small and medium-sized companies to manufacture vehicles with their own designs, and opening up the motorcycle market, which was monopolized by several major manufacturers, to small and medium-sized companies. it can. The above is the embodiment of the present invention described in claim 4.

When the amount of heat generated by the battery is large and the battery needs to be cooled, the frame type of the present invention has a high degree of freedom in configuration, so it is easy to secure a passage for guiding the traveling wind to a predetermined place. Can do. In addition, since it is not necessary to consider resonance due to vibration, in the case of connecting a cylindrical member having a square cross section, it is possible to provide a through hole at an optimum position for ventilation and to install an electric fan in the hole. . The above is the embodiment of the present invention described in claim 5 of the present invention.

In electric motorcycles, how to load a heavy battery with a large volume is an extremely important issue in securing driving performance and cruising distance. Therefore, side cars and rear cars will be installed on the main body of the electric motorcycle to increase the number of passengers and increase the battery capacity. In addition, if the power of the battery mounted on the sidecar or rear car is consumed first, and then the control of using the battery of the motorcycle is performed, even if the running power is insufficient, if the sidecar or rear car is disconnected, the motorcycle It is possible to continue traveling alone. The above are the embodiments of the present invention described in claims 6 and 7.

This is impossible with an engine-type motorcycle, but in the case of an electric motorcycle, an in-wheel motor can be installed on the wheel of a side car or rear car to make it a driving wheel. Therefore, the present invention provides a completely new type of vehicle by integrally controlling the driving wheels of the side car and the rear car and the driving wheels of the motorcycle body. The above is the embodiment of the present invention described in claim 8.

In an electric motorcycle, unlike an engine-type motorcycle, it is possible to divide the battery to be mounted, and the amount and position of the battery can be changed according to the purpose of use. Therefore, taking advantage of this characteristic, if the central portion 26 of the frame 25 is configured to be detachable with bolts 27 in the frame configuration of FIG. 3, the wheel base and the battery mounting amount can be varied according to the application. The above is the embodiment of the present invention described in claim 9.

FIG. 4 is a schematic view showing an example of the steering apparatus according to the present invention. In engine-type motorcycles, the width of the main frame is limited by the width of the engine, making it impossible to make an extremely narrow motorcycle. However, in an electric motorcycle, it is possible to adopt a very narrow frame if the batteries are mounted in the front-rear direction. However, if an existing general steering mechanism is installed in a very narrow frame, it is poor in novelty and cannot be differentiated from an engine-type motorcycle, which may hinder industrial development. Therefore, the present invention provides an entirely new steering device in which the driver moves away from the existing steering device that swings the steering wheel and moves the grip back and forth.
Reference numeral 30 corresponds to a plate for attaching a handle in the existing steering apparatus, and swings with reference to the rotation center 28. At the rear part, a similar plate 31 is installed so that it can be swung around 29. The front and rear plates are rotatably connected to the left and right rods 32 and 33 by pin coupling portions 36 and 37. If the driver grips the left and right grips 34 and 35 attached to 32 and 33 and moves them back and forth alternately, the plates 30 and 31 swing, so that the steered wheels can swing left and right. With this configuration, the handle width can be set according to the frame. The front wheel hydraulic cylinder master cylinder 38 may be attached to the rod 33 or the like. It is also possible to eliminate the plate 31 and move the rods 32 and 33 back and forth while holding them with linear bearings.
In this configuration, when steering from a straight traveling state, a large moment can be applied to the plates 30 and 31, so steering can be performed with a weak force, and if the steering angle increases, the steering angle is proportional to the steering angle. A large operating force is required. Therefore, a fine steering operation can be easily performed, and there is an advantage that unnecessarily large steering can be prevented and straight running stability can be ensured on an expressway or the like. In addition, when the hub steering is adopted, the steering force can be varied or the anti-phase steering can be performed in accordance with the purpose and characteristics of the vehicle, which is extremely convenient and versatile. Furthermore, when considering the extension of the cruising distance in an electric motorcycle, the air resistance during traveling becomes a problem, but with the steering device of the present invention, the front projection area can be reduced, and the optimum configuration for an electric motorcycle. It can be said.

As described above, if any one of the configurations of claims 1 to 10 of the present invention is adopted, an extremely novel electric motorcycle capable of solving all the problems of the present invention can be easily provided.

According to the present invention, even a small and medium-sized business operator who does not have special production facilities can enter the electric motorcycle market, and the motorcycle market in an oligopoly state by a specific major manufacturer can be widely opened to the public. Can do. In other words, it can contribute greatly to the development of Japanese industry.
