Japan Mechanical Science (NO.05-39) Permanent Magnet Fixation concept for Linear Generator

  The present invention relates to a technique for converting a vertical movement of a wheel generated during traveling of a land vehicle mainly into electric power by a linear power generation method. Linear power generation is a mechanism that generates electricity by generating a voltage at both terminals of a coil by sliding either a magnet or a coil at a position opposite to the magnet vertically or horizontally. In the present invention, a coil located on the inner side of the magnetic working surface of the permanent magnet (hereinafter referred to as an inner power generating coil) or a coil located on the outer side of the magnetic working surface of the permanent magnet (hereinafter referred to as an outer power generating coil). ), A structure of a device for generating electricity by sliding either a magnet or a coil and a method for using the device.

  Problem 1: When a linear power generator is installed side by side on the outer periphery or side surface of a shock absorber as a vibration control device for suppressing vibration generated between the axle and the vehicle body while the land vehicle is traveling, It points out the problems inherent in the absorber and presents solutions for parallel installation.

Problem 2: When a power generation device that uses vibration generated between the axle and the body of a land vehicle is attached to the vibration mitigation device, the height of the installation location, the size of the accommodation area, The installation environment varies depending on the conditions. We present a linear generator that can be adapted to such an environment and a method for arranging the same.
It is an object of the present invention to solve the above problems.

As means for solving the problem 1, the shock absorber and the power generation device are separated from each other by an inner cylinder of the power generation unit and an elastic film body bellows installed on the upper part, and air is provided between the outer periphery of the shock absorber and the inner wall of the power generation device. Creates an air circulation space that can freely move up and down, moves the air through this space to lower the temperature of the shock absorber outer periphery, and in the case of heavy vehicles such as heavy loads, the air circulation space described above is moved to the outer periphery of the shock absorber. It has been proposed to install a plurality of fins inside to enhance the cooling effect.

Example 1, (See FIG. 1, FIG. 2, FIG. 3, FIG. 4, FIG. 5, FIG. 6, FIG. 7)
Place a space where air can freely flow around the outer circumference of the single cylinder shock absorber, install a linear power generator on the outer circumference, and connect the single cylinder shock absorber and the linear power generator with the upper and lower casing connection bars. It is a form. An upper housing holding part that covers the upper part of the entire apparatus including the power generator is installed on the piston rod of the shock absorber, and an air circulation hole is installed on the outer periphery of the center part.
For the air circulation hole, it is also effective to install a lattice or the like in order to prevent the entry of flying foreign matter. Next, the bellows of the inner elastic coating body is installed vertically downward toward the outer periphery of the air circulation hole. The power generation unit inner cylinder is installed at the lower part, and the lowermost part is erected and joined to the bottom circular plate. A plurality of inner power generating coils are arranged outside the cylinder.

Next, a sliding sleeve is installed vertically downward on the outer side of the inner elastic coating body of the upper housing holding part.
A plurality of inner magnetic working surfaces of permanent magnets whose inner and outer surfaces are magnetic working surfaces are arranged in a state where the inner power generating coils are not in contact with the inner power generating coil, facing the inner power generating coil. A sliding auxiliary roll or a linear bearing is installed from the inside or outside of the sliding sleeve to maintain an accurate vertical movement of the sliding jacket. Next, an outer elastic coating body bellows is installed in the lower part of the outermost periphery of the upper housing holding part. A power generation unit outer cylinder is installed in the lower part, and the lowermost part is brought upright and joined to the outermost periphery of the bottom circular plate. An outer power generation coil is installed on the inner surface of the power generation unit outer cylinder so as not to contact the permanent magnet at a position facing the outer magnetic working surface of the permanent magnet. The lowermost part of the power generation unit has a power generation unit bottom circular plate, and the power generation unit inner cylinder and the power generation unit outer cylinder are made to stand upright as described above.
In the state which comprises the above form, a single cylinder type shock absorber and a power generation part are connected with an upper housing connection bar and a lower housing connection bar. As a result, the shock absorber and power generator are isolated by the bellows of the elastic coating on the upper part and the lower part is isolated by the inner cylinder of the power generation part with the air circulation space, and the permanent magnet also moves up and down accompanying the vertical movement of the piston rod of the shock absorber The device performs linear power generation by the vertical movement of the axle.

In the air circulation space, air can enter and exit above and below the apparatus by an air circulation hole installed near the center of the upper housing holding part. Due to the vertical movement of the axle that occurs during vehicle travel, the upper housing holding part repeats vertical movement and changes the air pressure in the air circulation space. As a result, the air flows, and the temperature rise around the shock absorber is prevented. Also, leaked oil passes through this air circulation space and is discharged to the outside from the lower part of the air circulation space, so that the influence on the power generation device is avoided.

Example 2, (see FIG. 8, FIG. 9, FIG. 10, FIG. 11)
A space where air can freely flow is placed on the outer periphery of the multi-cylinder shock absorber, and a linear power generator is installed on the outside of the space, and the multi-cylinder shock absorber and linear power generator are connected by the upper and lower chassis coupling bars. It is a form to do. Compared with Example 1, the overall shape is that the shock absorber is changed from a single cylinder type to a multiple cylinder type, and the structure of the power generation unit and the connection method of the shock absorber are not changed.
Next, a plurality of heat dissipating fins are vertically installed on the outermost peripheral wall of the shock absorber. Air moves in the air circulation space by the vertical movement of the upper housing holding part of the device installed on the piston rod of the shock absorber. This air touches the fins and lowers the temperature, which reduces the temperature of the outer wall of the shock absorber. Also, the leaked oil passes through this air circulation space and is discharged to the outside from the lower part of the air circulation space, so that it does not affect the power generation device.

Example 3 (see FIGS. 12, 13, 14, and 15)
An example for reducing the overall outer diameter of a power generator installed in parallel with a single-cylinder or double-cylinder shock absorber for installation in a narrow place is shown.
In the same manner as in Example 1, the power generators are arranged side by side with a space through which air can freely flow on the outer periphery of the single-cylinder shock absorber by means of the upper housing connecting bar and the lower housing connecting bar. An upper housing holding part that covers the entire device is installed above the piston rod of the shock absorber, and an air circulation hole is installed in the outer periphery of the central part. Next, a bellows of the inner elastic coating is vertically installed on the outer periphery of the air circulation hole downwardly. The power generation unit inner cylinder is installed at the lower part, and the lowermost part is erected and joined to the bottom circular plate. A plurality of inner power generating coils are arranged on the outer surface, and the upper part is connected to the inner elastic coating body bellows. Next, a sliding sleeve is installed vertically downward on the outer side of the inner elastic coating body of the upper housing holding part. A plurality of permanent magnets whose inner one surface is a magnetic working surface is installed on the sliding sleeve at a position facing the coil so as not to contact the coil. A sliding auxiliary roll or a linear bearing is installed inside or outside the sliding sleeve to maintain accurate vertical movement of the sliding sleeve.

An outer elastic coating body bellows is installed vertically downward at the lower part of the outermost periphery of the upper housing holding part. The power generation unit outer cylinder is installed in the lower part, and the lowermost part is erected on the bottom circular plate and joined. Next, the single cylinder type shock absorber and the power generation unit are connected by the upper case connecting bar and the lower case connecting bar. The shock absorber and power generator are isolated by bellows with an elastic coating on the upper part and the lower part is separated by the inner cylinder of the power generation part, and the permanent magnets also move up and down along with the vertical movement of the piston rod of the shock absorber. As a result, the device performs linear power generation.
The oil leaked from the oil seal passes through this air circulation space and is discharged to the outside from the lower part of the air circulation space, so that it does not affect the power generation device.

Next, a plurality of heat dissipating fins are vertically installed in the air circulation space on the outer periphery of the shock absorber. Air moves in the air circulation space by the vertical movement of the upper housing holding part of the device installed on the piston rod of the shock absorber. This air can touch the fins to lower the temperature and lower the outer temperature of the shock absorber. In the unlikely event that oil leaks from the oil seal, the oil passes through the air circulation space and is discharged to the outside, so that the power generation device is not affected.
FIG. 12 shows an example applied to a single-cylinder shock absorber, in which the inner power generation coil is installed on the inner side and the power generation permanent magnet is installed on the outer side. In this case, the power generation permanent magnet slides on the outside of the coil. FIG. 13 shows an example applied to a double-cylinder shock absorber, in which a power generation coil is installed on the outside and a power generation permanent magnet is installed on the inside. In this case, the power generating coil slides outside the power generating permanent magnet.

Example 4 (See FIGS. 16, 17, 18, 19, and 20)
The problem is not only the oil leak of the shock absorber and the temperature rise of the outer wall surface as in the previous example, but only the oil leak. In this case, it is assumed that it is not necessary to isolate the shock absorber and the power generation unit completely independently.
The leaking oil is not discharged in large quantities at a time, but gradually leaks out over a long period of time. In order to cope with this, an oil receiving portion is placed outside the oil seal portion, and the safety of the power generator is ensured as a form in which the oil flowing out is discharged from the lower part or the side surface of the shock absorber by a thin tube. The contents of the power generation section are the same as those of the previous four examples, with the single-cylinder and double-cylinder shock absorbers facing the inner magnetic working surface of the inner power generation coil and permanent magnet, and the outer power generation coil and permanent magnet. 1 shows a power generator that generates power by making the outer magnetic working surface and the outer power generating coil face each other and changing the vibration generated by the vertical movement of the axle to the vertical movement of the permanent magnet.

Example 5 (see FIGS. 21 and 22)
Introducing a wide range of applicable methods from large vehicles such as trains, trucks, buses, etc. to electric two-wheeled vehicles, other than the previous method, in which a linear power generator is installed on the outer periphery of the shock absorber.
A linear power generator is installed in parallel to the side of the shock absorber, or next to the suspension of large vehicles such as buses, trucks, trains, etc., and the coil or permanent magnet moves up and down in synchronization with the vertical movement of the piston rod of the shock absorber. In this way, a method for performing linear power generation is presented. The suspension axle side connection part and the linear power generator axle side connection part are connected horizontally, and a joint lower connection part is installed at the lower part thereof to connect with the axle side. Connect the vehicle body side connection part in parallel, install the joint upper connection part on the upper part and connect it with the vehicle body side, control the vibration due to the vertical movement of the wheel with the suspension, and generate the vibration due to the vertical movement of the wheel This section introduces a method of generating electricity by moving the permanent magnets up and down. In this case, in the case of a large vehicle, a shocking metallic shock is applied to the vibration control device and the power generation device, and a shock absorber made of an elastic material is installed at the joint so as to obtain a smooth vertical motion.

The contents of the power generation section are the same as the vertical movement of the piston rod of the suspension and the vertical movement of the sliding sleeve in the power generation section. Presenting a power generator with a method of generating electricity by changing the vibration caused by the vertical motion of the axle to the vertical motion of the permanent magnet by making the magnetic power surface face each other and the outer magnetic working surface of the outer power generating coil and the permanent magnet facing each other. doing. In this case, the position of the power generating coil and the permanent magnet is reversed, and the inner power generating coil and the permanent magnet are used by using a permanent magnet whose one side is a magnetic working surface in accordance with the shape of the suspension or the installation environment. It is also possible to make the power generation device generate power by changing the vibration generated by the vertical motion of the axle to the vertical motion of the permanent magnet and oppose the outer working surface of the axle, and the outer diameter of the power generation unit can be small.

See Example 6, (Fig. 23, Fig. 24, Fig. 25) An air suspension is installed at the upper part of the linear power generator, a power generator by the linear power generator is installed at the lower part, and a coil spring is installed outside if necessary. We present a means to demonstrate both suspension and power generation functions without using a shock absorber.
As for the shape, an air damper part for suspension function is placed on the upper part, and a power generation part with linear power generation function is placed on the lower part. Furthermore, if necessary, a coil spring can be installed outside the apparatus to enhance the function as a damper. A circular bottom is installed at the upper part of the axle connection, the main shaft is erected at the center upper part, a linear bearing is installed at the upper part, a piston rod is inserted into this, and the uppermost part of the piston rod is connected to the body of the car body. Install the upper frame holder. Next, the power generation unit outer cylinder is erected on the outermost periphery of the circular bottom, and the elastic coating body bellows is installed on the uppermost part.
The uppermost part of the elastic film body bellows is connected to the outer periphery of the upper housing holding part, and the upper part of the power generation part is covered with an upper partition plate. A plurality of inner coils for linear power generation are installed outside the main shaft.

A sliding sleeve is installed on the outer periphery of the piston rod located in the power generation section, and an inner magnetic working surface of a permanent magnet whose both surfaces are magnetic working surfaces is disposed on the sliding sleeve at a position facing the inner power generating coil. Are arranged so as not to contact the inner coil for power generation. A sliding auxiliary roll or a linear bearing is installed inside or outside the sliding sleeve so as to maintain accurate vertical movement of the sliding sleeve. An outer coil for power generation is arranged on the inner surface of the outer cylinder of the power generation unit at a position facing the outer magnetic working surface of the permanent magnet whose both surfaces are the magnetic working surfaces so as not to contact the permanent magnet. The piston rod moves up and down by the vibration caused by the vertical movement of the wheel, and all the permanent magnets move up and down in front of the coils at the opposite positions to generate an electromotive force. With the above operation, the present device exhibits the damper function of the air cushion and the function of the linear power generator. In order to enhance the vibration control function, a coil spring is installed on the outer periphery of the device to increase the buffering force.

Effect 1,
When a shock absorber and a linear generator are installed side by side and the vibration of the vertical movement of the wheel that occurs while the vehicle is running is converted into electric power, the problem on the shock absorber side is that it is used over a long period of time. The oil used inside the shock absorber may leak due to wear of the oil seal, and the outer circumference of the shock absorber used for heavy vehicles may rise in temperature due to the vertical movement of the internal piston. Is that there is.
According to the present invention, the function part of the shock absorber and the function part of the linear power generation are separated by the air circulation space, and in addition, when fins are installed on the outer periphery of the shock absorber, the contact area with the air increases, thereby the shock absorber. In the event that the temperature rise at the outer periphery is suppressed and the oil in the shock absorber leaks, the oil is discharged out of the system through the air circulation space, so that adverse effects on the power generation apparatus can be avoided.

Effect 2,
If only the oil leakage of the shock absorber described in Effect 1 is a problem, install an oil receiving part outside the oil seal part, and discharge from the system from the bottom or side of the device using a thin tube from here. The influence on the power generator can be avoided.

Effect 3
The ability to install a power generator parallel to the seismic control device from a large vehicle to an electric two-wheeled vehicle enables problems such as oil leakage and temperature rise to not directly affect the power generator, and the shape and production. The process is simplified, the cost is reduced, and the scope of application is expected to be expanded, which has a great effect on the improvement of the global environment.

This supplements the vibration control function.

Assignment 1,
The idea of changing the vibration caused by the vertical movement of the wheels generated during the traveling of a land vehicle into electric power has been introduced in the past as prior art. However, many problems need to be overcome to achieve this. It is necessary to install these devices in a narrow space where many foreign objects are expected to fly at the bottom of the vehicle body. In the present invention, a linear power generator is arranged in parallel on the outer periphery of a shock absorber as a shock absorber that absorbs vibration caused by vertical movement of a wheel during vehicle travel, and the linear power generator coil or permanent is moved by vertical motion of a piston rod of the shock absorber. The magnet is coupled so as to cause the same vertical movement as the piston rod, and is intended to generate power by the relative position change of the permanent magnet and the coil.

The problems in this case are oil leakage of the shock absorber due to long-term use and heat generation at the outer periphery of the shock absorber. In order to solve this problem, in the present invention, a space in which air flows is installed on the outer periphery of the shock absorber to lower the temperature by circulating air, and further, fins are installed on the outer periphery of the shock absorber and The contact area is increased to increase the effect of temperature reduction, and the leaked oil is discharged to the outside through this air circulation space, and the upper housing holding part is connected to the piston rod, and the piston rod moves up and down with the vertical movement. A system is also proposed in which the air pressure fluctuates and the air pressure fluctuates to prevent air stagnation in the air circulation space.

Issue 2,
There is also a method of installing a power generator on the outer periphery of the shock absorber as described above when changing the vibration due to the vertical movement of the wheel generated during the traveling of the land vehicle to electric power, but in the case of oil leakage as described above The handling method becomes complicated, and the work in the environment under the floor of the vehicle also takes time. In this case, the power generation device is placed side by side with the vibration control device so that both devices can be individually maintained, thereby facilitating the work. It is also possible to adopt different types of vibration control devices.
The problem in this case is that depending on the installation conditions of the vibration control device, vibration transmitted from the axle is transmitted to the upper and lower connection parts of the power generation device at the same time as a metallic rebound, which affects the power generation efficiency and the life of the device. There is concern. We must consider solving this problem at the same time.

Example 1.
1, 2, 3, 4, 5, 6, 7, 14, 15 are related to claim 1.
In this example, a linear power generator is arranged in parallel on the outer periphery of a single-cylinder shock absorber.
The single-cylinder shock absorber is joined to the vehicle body by an upper joint (1) to the vehicle body, and the bottom is joined to the axle by a lower joint (32) to the axle. The upper part of the shock absorber and the power generation device are air flow between the outer wall of the piston cylinder (21) of the shock absorber and the inner cylinder (10) of the power generation part by the upper housing connecting bar (9) at the lower part and the lower housing connecting bar (31) at the lower part. The spaces (28) are connected to each other.

The upper joint portion (1) to be joined to the vehicle body side of the device is connected to the shock absorber piston (23) by the piston rod (4) of the lower shock absorber. The piston (23) of the shock absorber moves up and down in the oil layer of the piston cylinder (21) of the shock absorber by vibration caused by the vertical movement of the wheel generated while the vehicle is running. The piston (23) of the shock absorber is installed in the piston (23) of the shock absorber to shock the amount of oil flow between the upper oil layer (22) of the shock absorber and the lower oil layer (25) of the shock absorber. It is adjusted by a regulating valve in the piston orifice (24) of the absorber. A shock absorber free piston (26) is provided below the shock absorber lower oil layer (25), and an air layer (27) below the shock absorber is provided below the shock absorber free piston (26). The air layer (27) under the shock absorber repeats compression and expansion due to repulsion by vibration caused by the vertical movement of the wheel. The vibration is absorbed by the above operation.

In this example, the air circulation space (28) is arranged on the outer periphery of the piston cylinder (21) of the single cylinder type shock absorber, the power generation unit inner cylinder (10) is arranged on the outer side, and the power generation unit inner cylinder (10). A plurality of inner power generation coils (12) are installed on the outer side of the inner coil support member (11). The power generation unit inner cylinder (10) has an upper part joined to an upper case holding part (2) joined to an upper part of a piston rod (4) of a shock absorber by an inner elastic film body bellows (5), and a lower part is a power generation part. Join the bottom circular plate (30).
Next, an inner magnetic working surface (13) of a permanent magnet for power generation whose both surfaces are magnetic working surfaces at positions facing the inner power generating coil on the outer periphery of the inner power generating coil (12) 12) It arrange | positions in the state which does not contact.

  Each of the permanent magnets is joined to the power generation magnet holding metal fitting (15) by the magnet holding material (14), and the upper part of the power generation magnet holding metal fitting (15) is connected to the upper sliding sleeve (6). The uppermost part of the sliding sleeve (6) is joined to the upper housing holding part (2), the lower part is joined to the lower sliding sleeve (19), and the lower sliding sleeve (19) is the power generation unit inner cylinder (10). Alternatively, the accuracy of vertical movement is maintained by a sliding auxiliary roll or linear bearing (29) installed in the power generation unit outer cylinder (20), and then the outer side operation of the permanent magnet having the circular shape and both surfaces serving as magnetic operating surfaces. The outer power generation coil (17) is installed inside the power generation unit outer cylinder (20) by the outer coil support member (18) at a position not in contact with the magnetic actuation surface at a position facing the surface (16). Next, the upper part of the power generation unit outer cylinder (20) is joined to the upper housing holding part (2) of the device by the outer elastic coating body bellows (7), and the lower part is joined to the power generation unit bottom circular plate (30).

  Thus, the shock absorber and the power generation device are separated from each other by the air circulation space (28). The piston rod (4) of the shock absorber repeatedly moves up and down by the vibration of the axle. This vertical movement is the vertical movement of the connected upper housing holding part (2), the inner magnetic working surface (13) of the permanent magnet installed on the upper sliding sleeve (6) joined to this, the outer side of the permanent magnet The magnetic working surface (16) moves up and down simultaneously. As a result, electric power is generated in the inner power generation coil (12) and the outer power generation coil (17) installed at the opposing positions.
