DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bag having a built-in power supply for driving a personal computer that can be stored.

[0002]

2. Description of the Related Art A laptop personal computer has a built-in battery. Therefore, it can be conveniently used in places where there is no commercial power supply such as AC 100V. However, recent personal computers have significantly increased power consumption in order to increase the processing speed. For example, a 486-SX (Intel) CPU consumes 0.8 to 1 W, but a Pentium 150 MHz (Intel) consumes 8 W
And becomes significantly larger. In response to such demands, secondary batteries have also been improved from nickel cadmium batteries to nickel-metal hydride batteries, and lithium ion secondary batteries and large capacity batteries have been developed. Lithium ion secondary batteries are
Since the capacity can be increased by about 3 to 4 times as compared with the nickel cadmium battery, the power supply capacity can be increased several times with the same weight. Thus, the capacity of the secondary battery has been dramatically improved. Nevertheless, the battery life of laptop computers is not extended, but rather shortened. Laptop computers are portable,
It can be conveniently used anytime and anywhere, but the usage time is considerably limited by the capacity of the battery. At present, most of the laptop personal computers actually on the market limit the maximum use time to about 3 hours. For this reason, it is necessary to always use the battery while paying attention to the remaining capacity in a usage state that requires a certain amount of time, and the battery may run out during work and become unusable. Furthermore, the battery built in the personal computer is not always fully charged in an ideal state, so that the actual use time is shorter than the maximum use time.

In order to solve such a drawback, a technology has been developed in which a secondary battery is incorporated in a bag carrying a laptop-type personal computer (Japanese Patent Laid-Open No. Hei 8-66217).
No.). The bag described in this publication incorporates a secondary battery at the bottom and a charger for the secondary battery. Since the rechargeable battery built into the bag is used to power the PC,
After the battery built into the personal computer is discharged, or
Power can be supplied to the PC without using the battery built into the PC. For this reason, there is a feature that the use time of the laptop personal computer can be extended.

[0004]

However, the bag described in this gazette has a drawback that a personal computer that can be stored and used is specified and cannot be used for various personal computers. This is because the structure of the connector for connecting the secondary battery and the personal computer differs depending on the personal computer, and the DC voltage supplied to the personal computer also differs depending on the type of the personal computer. The secondary battery that supplies power to the personal computer adjusts the type and number of stored secondary batteries, outputs a voltage suitable for the personal computer, and connects this secondary battery to the personal computer with a dedicated connector There is a need. For this reason, a personal computer using a different DC voltage can be stored in a bag, and power cannot be supplied to the personal computer. In addition, if the connector for supplying DC power to the personal computer is different, a secondary battery cannot be connected to the personal computer. Therefore, the bag described in this publication requires a structure in which the rechargeable battery is adjusted so as to have a DC voltage suitable for the personal computer to be stored, and further, can be connected to the personal computer to be stored by a connector dedicated to the personal computer. There is a drawback that only specially designed personal computers can be stored and used.

[0005] The present invention has been developed for the purpose of further solving this drawback. An important object of the present invention is to store a variety of personal computers having different DC voltages supplied to the personal computers, or having different connection connector structures, without specifying the type of personal computer to be stored in the bag. It is an object of the present invention to provide a bag for a personal computer which incorporates a power supply that can be used for a long time by supplying power from a battery.

The power source is a secondary battery 21 for supplying power to the personal computer 1 and the secondary battery 2
1 for charging the battery 1.

Further, the bag of the present invention is equipped with an inverter 23 for converting a direct current output from the secondary battery 21 into an AC voltage of a commercial power supply capable of driving the power supply circuit 25 of the personal computer 1. Furthermore, this inverter 23
Has an outlet 24 connected to the output side. Power supply circuit 25 for supplying DC power to personal computer 1 stored in a bag
The AC power is supplied by connecting the power plug 26 to the outlet 24. That is, the personal computer 1 is not supplied with DC power from the secondary battery 21 incorporated in the bag, but the DC power of the secondary battery 21 is converted into the AC voltage of the commercial power supply, and the power supply circuit 25 of the personal computer 1 , And DC power is supplied from the power supply circuit 25 of the personal computer 1 to the personal computer. The power supply plug 26 and the outlet 24 connected to the power supply circuit 25 of the personal computer 1 do not have various shapes, such as a connector for supplying DC power to the personal computer 1. The power plug 26 and the outlet 24 have a certain standard and are used at a certain voltage so that various electric appliances can be used with a commercial power supply. Therefore, the power plug 2
The secondary battery 21 connected to the personal computer 1 via the power outlet 6 and the outlet 24 can be used by being connected to various types of personal computers regardless of the type of the personal computer 1 to be stored. For this reason, the bag of the present invention does not need to be specially designed for a personal computer to be stored, and has a feature that it can be used for a long time by supplying power from a secondary battery built in any type of personal computer that can be stored.

The bag body 4 includes a bottom surface 4A, vertical surfaces 4B on both sides connected to both ends of the bottom surface 4A, and an upper surface 4C connecting the upper ends of the vertical surfaces 4B. The bag body 4 is formed in a rectangular shape that is long horizontally with a bottom surface 4A, a vertical surface 4B, and a top surface 4C, and has openings on both sides.

[0013] The thickness of the bag is preferably 10 cm or more so that the luggage can be stored on a caster 2 to be self-supporting and run independently. The bag preferably has a size of the bottom surface 4A of 1
The height is set to 0 × 20 cm or more so as to be able to stably move vertically. As shown in the figure, a bag that divides the inside into two sides and stores the personal computer 1 on one side has a width of 20 cm.

As shown in the sectional view of FIG.
A rectangular reinforcing frame 7A is provided on the inner surface, and a hard plate lining 7B and a soft surface material 8 are provided on the surface of the reinforcing frame 7A.

The reinforcing frame 7A is formed by bending a hard plastic plate such as hard vinyl chloride resin or polyethylene into a frame shape along the inner surface of the bag body 4. The reinforcing frame 7A having this structure has a lightweight and tough characteristic. However, in the reinforcement frame,
Aluminum or a thin iron plate can also be used.

The hard plate lining 7B is a cardboard, thin and hard plastic plate. The hard plate lining may be formed by laminating a plurality of same or different materials. In the bag shown in the figure, the reinforcing frame and the hardboard lining are separate members,
Both may have an integral structure. Further, the reinforcing frame can be omitted from the bag.

The soft surface material 8 is a cloth or a plastic sheet. In the bag body 4 shown in the figure, a decorative material in the form of a strip of natural or synthetic leather is sewn to the center of the outside of the soft surface material 8.

Further, a bottom surface 4A, a vertical surface 4B, and a top surface 4C

As the partition 9, a hard plate made of ABS plastic is used. The partition 9 has an outer shape substantially equal to the inner shape of the bottom surface 4A, the vertical surface 4B, and the upper surface 4C. This is for connecting to the inside of the bag body 4 to reinforce it. The partition 9 which is a hard plate made of ABS resin has a light and tough characteristic. However, the bag of the present invention does not specify the material of the partition as ABS resin. For the partition, for example, a plate-shaped product of vinyl chloride resin, nylon, acrylic resin, polyethylene resin, epoxy resin, or the like can be used. Furthermore, instead of a plastic plate for the partition,
Metal plates such as aluminum and iron can also be used. Since the partition of the plastic plate or the metal plate has sufficient strength, a plurality of through holes can be locally opened to reduce the weight.

FIG. 4 shows that the partition 9 which is a hard plate is

The partition 9 has at least upper and lower portions on both sides fixed diagonally to the vertical surface 4B of the bag body 4. Furthermore, the partition can also fix the upper edge to the upper surface of the bag body and the lower edge to the bottom surface. The partitions fixed to the vertical surface, the top surface, and the bottom surface reinforce the bag body more strongly and are fixed.

The partition 9 is fixed at the center or substantially at the center of the bag body 4 as shown in the sectional views of FIGS. This is because a compartment 10 having substantially the same volume is provided inside the bag body 4 and the personal computer 1 is stored in the compartment 10. However, the compartments 10 on both sides have the exact same volume,
In other words, it is not necessary to have the same depth. PC 1
Is designed to be approximately the thickness of the personal computer 1. This is to prevent the upper surface 4C of the bag body 4 from getting in the way when hitting the keyboard of the personal computer 1 stored here. If the personal computer 1 is stored in the compartment 10 in a deeply sunk state, when operating the keyboard, the upper surface 4C of the bag body 4 becomes an obstacle and cannot be used conveniently. Therefore, in a bag provided with two compartments 10 at the partition 9, the depth of at least one compartment 10 is made substantially equal to the thickness of the personal computer 1, so that the keyboard of the personal computer 1 stored therein can be easily operated. .

Further, the bag shown in FIG. 2 and FIG.

It is time to lift your bag and carry it.

The total length of the vertical rod 3B is designed so that the height from the lower end of the caster 2 to the grip portion 3A is about 80 cm when the handle 3 is pulled up most. However, the height from the lower end of the caster 2 to the grip part 3A is 60 to
It can be changed in the range of 100 cm. Grip part 3A
When the height is about 80 cm, you can most easily push and move your bag. The grip portion 3A connected to the upper end of the vertical rod 3B extends in the longitudinal direction on the upper surface 4C of the bag, and the grip portion 3A is extended.
A. The grip portion 3A pulls out the two vertical rods 3B to the same length and is held horizontally.

FIG. 5 shows a bag in which the guide cylinder 11 is connected to the bag body 4 instead of the partition 9. In the bag shown in this figure, a reinforcing frame 7A is fixed to the inner surface of the bag body 4. As the reinforcing frame 7A, one having the same structure as the bag shown in FIG. 3 can be used. In the bag of this figure, as shown in the cross-sectional view of FIG. 6, a partition 9 is fixed inside the bag body 4 to divide the inner surface of the bag body 4 into two compartments 10. The guide tube 11 penetrates the upper reinforcing frame 7A, and is connected to the reinforcing frame 7A via the fixture 19 without penetrating the lower reinforcing frame 7A. The fixture 19 is made of plastic, and is formed by integrally forming a flange with a tube portion into which the guide tube 11 is inserted. In the fixing device 19 having this structure, the guide tube 11 is fixed to the bag body 4 by inserting the guide tube 11 into the tube portion and fixing the flange portion to the inner surface of the reinforcing frame 7A by screwing or bonding. doing.

Further, the caster 2 is fixed to the bag at four corners on the bottom surface of the bag body 4. The caster 2 is fixed to the wheel base 5. The wheel base 5 is fixed to the bottom surface of the bag body 4. The wheel base 5 is separated into two pieces, lightened as a whole, and fixed to the bottom surface 4A of the bag body 4 via screws or rivets. However, the wheel base can be approximately the same size as the bottom surface of the bag body. The wheel base 5 is made of a metal plate such as aluminum so as to have sufficient strength. The wheel base 5 made of aluminum preferably has a thickness of 2 to 5 mm, more preferably 3 to 4 mm. In order to reduce the weight of the wheel base, a through hole can be partially opened.

The casters 2 are fixed to the wheel base 5. The casters 2 are located at four corners of the bottom surface 4 </ b> A of the bag body 4 and are fixed to the wheel base 5. The caster 2 can be swung freely, and a so-called "free wheel" is used. However, all four casters shall not be swinging type, two casters arranged on one side of the bag body shall be swinging type, and the other two casters shall not be swinging type. Can also. The casters 2 are fixed to the lower surface of the wheel base 5 via screws and rivets.

In the bag of the present invention, the bag body is not specified to the above-mentioned structure. As shown in FIG. 7 and FIG.
It is also possible to adopt a structure in which the lid 6 that can be opened and closed is connected via the. In this bag, a bag body 4 and a lid 6 are formed of a hard material having sufficient strength, for example, a fibrous material formed by curing and bonding with a binder into a plate shape, and a paint on the surface of water-resistant hard paper. It is formed of a coated material, a hard plastic, or a metal such as aluminum. The bag body 4 and the lid 6 are designed to have a thickness that does not deform even when a considerably heavy object is stored.

In the bag of this figure, as shown in the sectional view of FIG. 8, a partition 9 of a hard plate is fixed inside the bag body 4, and a guide cylinder 11 is fixed to the partition 9 via a saddle 16. The vertical rod 3B of the handle 3 is inserted into the guide tube 11. The bag having this structure is characterized in that the bag body 4 is reinforced with the lids 6 on both sides and the partition 9 which is a hard plate, so that an extremely tough structure can be achieved. Furthermore, since the bag shown in this figure is attached so that the handle can be pulled out in the vertical direction, when using the personal computer with the lid 6 opened, the handle 3 can be pulled out sideways and used together with the platen. is there.

As shown in the block diagram of FIG. 9, a power supply built in the bag includes a secondary battery 21, a charger 22 for charging the secondary battery 21, and a DC output from the secondary battery 21. An inverter 23 for converting an AC voltage of a commercial power supply capable of driving a power supply circuit 25 of the personal computer 1, and an outlet 24 connected to an output side of the inverter 23. A power supply built in the bag is connected to a power plug 26 connected to a power supply circuit 25 of the personal computer 1 by an outlet 24.
The power supply circuit 25 supplies AC power to the power supply circuit 25 of the personal computer 1 and supplies DC power from the power supply circuit 25 to the personal computer 1 so that the personal computer 1 can be used.

The bag shown in FIGS. 3 and 4 has a power supply inserted between two partitions 9. The secondary battery 21 is disposed between the two guide tubes 11, and the charger 22 and the inverter 23 are disposed outside the guide tubes 11. Power supply to two partitions 9
The bag disposed between them has a feature that the power supply is stored in a useless space formed inside the bag body 4 and the internal space can be used very effectively. However, as shown in FIG. 10, the power supply may be provided at the bottom of the bag body 4. Also, the inverter and the charger can be arranged at the bottom of the bag body, and the secondary battery can be arranged between the two partitions. Still further, the inverter can be arranged at the bottom of the bag body, and the charger and the secondary battery can be arranged between the two partitions.

When the secondary battery 21 is used for a certain period of time and repeatedly charged and discharged many times, the actual capacity is reduced. For this reason, the portion for accommodating the secondary battery 21 has a structure in which the secondary battery 21 can be replaced with a new one, for example, as shown in FIG.
A window 9A that can be opened and closed is opened in a part of the partition 9 as shown in FIG. The secondary battery 21 is stored in the bag body 4 in a state of a battery pack in which a plurality of secondary batteries are built in a case.
The battery pack can be easily replaced, and a battery protection circuit and the like can be incorporated.

As the secondary battery 21, a battery that can be charged and reused many times, such as a nickel-hydrogen battery, a lithium ion secondary battery, and a nickel cadmium battery, is used. The secondary battery 21 has a capacity that allows the personal computer 1 to be used for several hours or more. Nickel-metal hydride batteries and lithium ion secondary batteries can be small and have large capacities. Further, the capacity for the volume of the lithium ion secondary battery is almost the same as that of the nickel-hydrogen battery, but the capacity for the weight can be further increased. Therefore, a nickel-hydrogen battery or a lithium ion secondary battery is most suitable as the secondary battery.

The charger 22 converts a commercial power supply of 100 V AC in Japan into a DC voltage for charging the secondary battery 21, and charges the secondary battery 21. Bags used in each country are chargers provided with a switching circuit for input voltage. The charger 22 shown in the figure is also connected to a plug 27 inserted into a cigarette lighter so that the battery can be charged from a car battery. The charging circuit for charging the secondary battery 21 with the commercial power supply converts the alternating current of the commercial power supply into a charging voltage of the secondary battery 21 with a transformer, converts the voltage into a direct current, and supplies the charge to the secondary battery 21 via a circuit for controlling charging. Connected. The charging circuit for charging the secondary battery 21 with the vehicle battery converts the voltage to the charging voltage of the secondary battery 21 with a DC-DC converter, and is connected to the secondary battery 21 via a charging control circuit.

The charger 22 has a built-in charge control circuit that stops charging when the secondary battery 21 is fully charged. A charger for a nickel-hydrogen battery or a nickel-cadmium battery has a built-in charging circuit that performs constant current charging to fully charge a secondary battery. Lithium-ion rechargeable battery chargers
It has a built-in charging circuit that charges the rechargeable battery with a constant voltage and constant current.

The inverter 23 converts a DC output of the secondary battery 21 into an AC voltage of a commercial power supply. Japanese commercial power is 100 V AC with a frequency of 50 or 60 Hz. Therefore, when used in Japan, the inverter 23 is, for example, connected to the secondary battery 21 at an AC voltage of 100 to 110 V with a frequency of 50 or 60 Hz or 55 Hz.
Is converted and output. The power supply circuit 25 of the personal computer 1 operates normally even if the frequency of the alternating current output from the inverter 23 deviates slightly from 50 to 60 Hz.
Therefore, the inverter 23 does not need to adjust the frequency of the AC output to 50 to 60 Hz accurately. The inverter 23 outputs an alternating current having a frequency capable of driving the power supply circuit 25 of the personal computer 1, for example, 40 to 100 Hz.
The output of the inverter 23 is a sine wave or a square wave. The inverter 23 has a built-in stabilizing circuit that controls the output voltage to be constant even when the DC voltage of the secondary battery 21 fluctuates. This is because the voltage decreases as the secondary battery 21 discharges. For example, the lithium ion secondary battery used for the secondary battery 21 has a voltage of 4.1 to 4.2 V / cell when fully charged, but the voltage decreases as the battery is discharged. The battery is typically discharged until the voltage drops to 2.5V. For this reason, the battery voltage fluctuates considerably from 2.5 to 4.2 V. The inverter 23 having a built-in stabilizing circuit for preventing the fluctuation of the battery voltage and controlling the output voltage to be constant has a feature that the power supply circuit 25 of the personal computer 1 can be normally driven until the battery is completely discharged. When used in Japan, the output voltage of the inverter is set to 100V, but when used in a country other than Japan, the output voltage of the inverter is set to the voltage and frequency of the commercial power supply in that country. further,
If the output voltage of the inverter is designed to be adjusted to the voltage of each country, personal computers of various countries can be used.

An outlet 24 is connected to the output side of the inverter 23. The outlet 24 is exposed and fixed inside the bag so that a power plug 26 connected to the power circuit 25 of the personal computer 1 can be inserted and easily connected. In the bag shown in FIG. 1, an outlet 24 is fixed to the partition 9.

A power plug 26 of a power adapter 28, which is a power circuit 25 of the personal computer 1, is connected to the outlet 24. Power supply circuit 2 built in power supply adapter 28
Reference numeral 5 converts the AC commercial power output from the inverter 23 into a DC voltage for driving the personal computer 1, and outputs the DC voltage. The output of the power adapter 28 is connected to the personal computer 1 via a lead wire and a connector, and supplies DC power to the personal computer 1. Laptop type personal computer 1
A power adapter 28 for use with commercial power is provided. In the bag of the present invention, instead of directly supplying the output of the secondary battery 21 to the personal computer 1, the output of the secondary battery 21 is converted to commercial power by the inverter 23,
8 to supply DC power to the personal computer 1.

Further, the personal computer bag of the present invention is shown in FIG.
The structure shown in FIG. The bag in this figure has a bottom 4
The caster of A is omitted. Further, the handle 3 is fixed to the upper surface 4C of the bag body 4 as a structure that does not expand and contract.
Further, since the inside of the bag body 4 is not partitioned by a partition, the bag body 4 is made thin. Although not shown, this bag may be configured to be carried over two shoulders, for example, like a rucksack. The two bands are
In the figure, it is connected to the bottom side of the bag. Since the inside of this bag is not divided into two parts by a partition, the bottom side can be closed without providing a lid on the bottom side.

The bag of the present invention can store various types of personal computers without specifying the model of the personal computer to be stored, and realizes a feature that the personal computers can be supplied with power from a secondary battery and used for a long time. I do. That is, the bag of the present invention does not directly supply the output of the secondary battery to the personal computer,
Convert the output of the secondary battery to commercial power with an inverter, connect the power circuit of the personal computer to the outlet of the commercial power,
This is because power is supplied to the personal computer. In a bag that supplies power to the personal computer in this state, there is no need to connect the secondary battery and the personal computer with a dedicated connector. Connect the power plug of the power circuit of the personal computer to the outlet of the commercial power supply,
This is because power can be supplied to the personal computer. The power plug connected to the power supply circuit of the personal computer has a unified standard, so that it has a structure that can be connected to a commercial power outlet even if the personal computer model is changed. For this reason, the structure that connects the outlet connected to the output of the inverter and the power plug of the power circuit is independent of the PC model.
