By the way, in the thing shown in the said patent document 1, in order to enlarge the power generation capacity of a power generation unit, it is necessary to enlarge the generator in a roller. However, if this is the case, the driving wheels must be arranged on the larger rollers, which causes the driving wheels to be lifted high. As a result, there is a risk that the self-propelled vehicle will tilt and fall, which is a problem in terms of safety. Occurs.

The present invention has been made in view of such a point, and an object of the present invention is to provide a highly safe power generation unit that can easily increase the power generation capacity.

The rotational force transmission mechanism includes a transmission roller that is provided integrally with the rotation roller and whose outer peripheral surface is in contact with the outer peripheral surface of the rotor so as to be capable of transmission, and rides on the rotation roller. Characterized in that as the rotor is power rotated by rotate the drive wheels of the motor vehicle to rotationally drive the rotating roller.

In the first invention, when the driving wheel of the self-propelled vehicle riding on the rotating roller is driven and rotated, the rotational force of the rotating roller is transmitted to the rotor of the power generation mechanism via the rotational force transmitting mechanism, and the rotor is transferred to the stator. The power generation unit generates electricity. In the first invention, the rotating shaft of the rotor of the power generation mechanism is located above the rotating shaft of the rotating roller.

In the first invention, the power generation mechanism is formed in a so-called outer rotor type, and the outer peripheral surface of the rotor formed in a substantially cylindrical shape is in contact with the outer peripheral surface of the transmission roller rotating integrally with the rotary roller. It is arranged to touch. If it carries out like this, a rotor will rotate with rotation of a rotating roller, and a power generation unit will generate electric power.

A self-propelled vehicle is a vehicle whose driving wheels rotate with an engine using gasoline or light oil as fuel, and includes ordinary cars, large cars, motorcycles, motorbikes, and the like.

According to a second invention, in the first invention, the rotational force transmission mechanism includes a clutch mechanism capable of adjusting a rotational force transmitted from the rotary roller to the rotor.

In the second invention, the torque transmitted from the driving wheel of the self-propelled vehicle to the rotor of the power generation mechanism is adjusted by the clutch mechanism.

In the first invention, the rotor of the power generation mechanism may have a rotating shaft extending in a direction different from the rotating shaft of the rotating roller.

In this case, in a configuration in which the rotating shaft of the rotor extends in a direction different from the rotating shaft of the rotating roller, the rotating force of the rotating roller is transmitted to the rotor by the rotating force transmission mechanism.

According to this, even if the rotating shaft of the rotor is not parallel to the rotating shaft of the rotating roller, the rotating force of the rotating roller can be transmitted to the rotor.

Further, the above configuration may be combined with the configuration described in the second to fourth inventions.

According to the first invention, the rotating shaft of the rotor of the power generation mechanism is arranged above the rotating shaft of the rotating roller. In this way, the power generation mechanism can be enlarged regardless of the size of the rotating roller. That is, the size of the rotating roller can be set to such a size that the self-propelled vehicle that rides on the rotating roller does not tilt significantly, and the power generation capacity of the power generation mechanism can be increased.

Further, according to the first invention, the rotor of the power generation mechanism formed in the outer rotor type can be rotated using the outer peripheral surface of the transmission roller. In this case, it is not necessary to separately provide a complicated mechanism such as a gear or a belt transmission mechanism in order to rotate the rotor, and the number of components of the power generation unit can be reduced.

Further, according to the second invention, the rotational force transmitted to the rotor by the clutch mechanism can be suppressed, so that the rotor can be prevented from over-rotating.

Further, according to the third aspect of the invention, the driving wheel of the self-propelled vehicle that rides on the rotatable rotating roller can be lifted from the rotating roller. Therefore, when lowering the self-propelled vehicle from the power generation unit, the driven wheel that has stopped rotating is lifted from the rotation roller by the drive wheel raising mechanism, and then the drive wheel is rotated again, so that the self-propelled vehicle is easily lowered from the power generation unit. be able to.

Further, according to the fourth invention, since not only the power generation mechanism but also the auxiliary power generation mechanism can generate power, the power generation capacity of the entire power generation unit can be increased.

The power generation mechanism (10) is a large power generation mechanism having a relatively large power generation capacity. In the first embodiment, two power generation mechanisms (10) are provided. Each power generation mechanism (10) is accommodated in the upper space inside the first base (3).

The hydraulic oil (25) is stored inside the tank part (21), and by operating the handle lever (not shown), the hydraulic oil (25) in the tank part (21) is stored in the cylinder (22). It can be sent to the lower hydraulic chamber (S) to raise the piston (23), or the hydraulic oil (25) in the hydraulic chamber (S) can be discharged to the tank (21) to lower the piston (23) It is like that.

-Operation of power generation unit-
When generating electricity with the power generation unit (1), first, the vehicle (50) is caused to travel slowly, and one of its drive wheels (51) is installed on the two rotating rollers (5). . (See FIG. 5A). Specifically, for example, when the automobile (50) is a front wheel drive vehicle, one of the two front wheels is installed on the rotating roller (5). When the automobile (50) is a rear wheel drive vehicle, one of the two rear wheels is installed on the rotating roller (5). At this time, the piston (23) of the hydraulic jack (20) is lowered to the lowest point, and the drive wheel support portion (24) is separated from the drive wheel (51).

As described above, the engine (not shown) of the automobile (50) is operated with the drive wheels (51) set in the power generation unit (1), and the automobile (50) is put into a running state. At this time, the drive wheel (51) in contact with the ground is rotated by a differential gear structure (not shown) provided between the speed change mechanism of the vehicle (50) and the drive wheel (51). However, only the driving wheel (51) on the rotating roller (5) with a relatively small load rotates. Then, the rotating roller (5) rotates due to the frictional force between the surface of the drive wheel (51) and the surface of the rotating roller (5). The rotational force of the rotating roller (5) is transmitted to the power generating mechanism side transmission roller (7) via the electromagnetic clutch (8), and the outer rotor (12) in contact with the outer peripheral surface of the transmitting roller (7) Rotate. Thus, power is generated by the power generation mechanism (10). The power generated in this way can be used after being converted into desired AC power by a converter (not shown), for example, or can be used after being stored in a storage battery.

On the other hand, when power generation is stopped, the engine of the automobile (50) is temporarily stopped (the rotation of the drive wheels (51) is stopped), and the hydraulic jack (20) is lifted so that the piston (23) rises. Operate the handle lever (20). As a result, the drive wheel (51) is lifted by the drive wheel support portion (24) and is separated from the rotating roller (5) (see FIG. 5B). When the engine is driven again in this state, the drive wheel (51) gets over the rotating roller (5), reaches the slope (4b), and goes down the slope (4b). Thereby, the automobile (50) can be lowered from the power generation unit (1).

-Effect of Embodiment 1-
As described above, the power generation mechanism (10) according to the first embodiment is disposed above the rotating roller (5). In this way, the power generation mechanism (10) can be enlarged regardless of the size of the rotating roller (5). Therefore, the size of the rotating roller (5) can be set to such a size that the automobile (50) riding on the rotating roller (5) does not tilt greatly, and the power generation capacity of the power generation mechanism (10) can be increased.

In the power generation mechanism (10) according to the first embodiment, the outer peripheral surface of the outer rotor (12) is brought into contact with the outer peripheral surface of the transmission roller (7) that rotates integrally with the rotating roller (5). This eliminates the need for providing a complicated mechanism such as a belt transmission mechanism or a gear mechanism as the rotational force transmission mechanism (6) for transmitting the rotational force of the rotating roller (5) to the outer rotor (12). Therefore, the number of parts of the power generation unit (1) can be reduced.

In Embodiment 1, it is possible to suppress the rotational force transmitted from the drive wheels (51) to the outer rotor (12) by operating the electromagnetic clutch (8) as necessary. Therefore, for example, it is possible to prevent an overcurrent from flowing in a coil (not shown) of the power generation mechanism due to the overrotation of the outer rotor (12).

In the first embodiment, since the hydraulic jack (20) for raising the drive wheel (51) riding on the rotating roller (5) is provided, the drive wheel (51) is relatively easily attached to the power generation unit (1). Can be taken down from.

-Modification of Embodiment 1-
As shown in FIG. 6, the power generation unit (1) according to this modification includes two auxiliary power generation mechanisms (60, 60). The auxiliary power generation mechanism may be one or three or more.

Each auxiliary power generation mechanism (60) includes a stator (61) and an outer rotor (62), similar to the power generation mechanism (10). A support shaft (63) fixed to the base (2) is inserted into and fixed to the stator (61). The outer rotor (62) is formed in a substantially cylindrical shape that accommodates the stator (61) therein, and is rotatable with respect to the stator (61) fixed to the base (2). The two auxiliary power generation mechanisms (60, 60) are arranged such that their outer peripheral surfaces are in contact with the outer peripheral surface of the outer rotor (12) of the power generation mechanism (10). Although not shown, the outer rotor (62) rotates on the outer peripheral surface of the outer rotor (62) of the auxiliary power generation mechanism (60) while sliding relative to the outer rotor (12) of the power generation mechanism (10). Anti-slip is formed to prevent this. The slip stopper can be formed by, for example, a plurality of convex portions, concave portions, and groove portions.

In the power generation unit (1) having such a configuration, when the driving wheel (51) of the automobile (50) is rotated to drive the power generation mechanism (10), the outer rotor (12) of the power generation mechanism (10) is rotated. Along with this, the outer rotor (62) of the auxiliary power generation mechanism (60) rotates, and electric power is generated by the auxiliary power generation mechanism (60). That is, in the power generation unit (1) according to this modification, power generation is performed not only by the power generation mechanism (10) but also by the auxiliary power generation mechanism (60).
