Description

 The present invention relates to a solar panel filled with solar energy.

In recent years, there is a tendency to use solar panels to charge mobile batteries and to charge solar energy. In the case of mobile, unlike a roof or a huge solar panel which is fixed on the land and used, it is carried, and therefore, it is required to be compact at the time of carrying and easy to miniaturize.

However, when using a solar panel, to obtain a large output, the area of the panel tends to be large, and carrying by the large area tends to be inconvenient.

In connection with this, Patent Document 1 discloses that a power generation device that converts solar energy into electrical energy is configured to be foldable.

Also, it is disclosed that the power generating device is attached to the leg of a telescopic tripod. However, even if the power generation device is considered to be portable, it does not reduce the size of the device itself nor fold it, and is not suitable for charging a mobile battery.

Patent Document 2 discloses that a plurality of thin plate-like solar panels are supported by an elongated support pivotable about one axis and fan-likely spread around the axis. .

However, if the support is vertically long and a plurality of thin solar panels are folded and stored and carried, a large container is required.

One end of each of the four solar panels is disposed on one end side of the shaft member 30, and when opened by the user, the four solar panels are formed in a plane shape in the direction of radiation of sunlight. The lower solar panel 201 according to the present embodiment is formed horizontally to the ground when opened by the user. When opened by the user, one lower solar panel 201 is formed in the gap between the two upper solar panels 101. Therefore, when viewed as a whole, each of the four lower solar panels 201 is formed in the gap of each of the four upper solar panels 101 when opened by the user.

  The tripod 300 supports the solar panel system 1 against the ground when in use. The battery 400 is attached to the tripod 300 when the solar panel system 1 is used, and is connected to the upper stage member 100 and the lower stage member 200. Therefore, the battery 400 is connected to the upper solar panel 101 and the lower solar panel 201 when the solar panel system 1 is used. The battery 400 is incorporated in the shaft member 30, at least integrated, and connected to the upper solar panel 101 and the lower solar panel 201. The battery 400 makes it possible to store power generated based on the light receiving surfaces of the upper solar panel 101 and the lower solar panel 201.

  In the present embodiment, the upper solar panel 101 and the lower solar panel 201 will be described by way of an example each having four panels, but the number is not limited to four. For example, the configuration may be such that three to six pieces are arranged at the upper stage and the lower stage, respectively. Here, the term “four” refers to the number of sheets in a state where panels are formed in a plane on each of the front, rear, left and right of the upper stage member when opened by the user. Further, in the solar panel of the present embodiment, when the solar panel is used, the four upper solar panels 101 and the four lower solar panels 201 are approximately 45 degrees apart from each other when they are rotated approximately 45 degrees from the center point in the horizontal direction. It is installed in an overlapping positional relationship. The four upper solar panels 101 are arranged orthogonal to one another, and the four lower solar panels 201 are also arranged orthogonal to one another, and if the intervals between the panels are equal, the 45-degree intervals It becomes arrangement to say. In the present embodiment, although the upper solar panel 101 and the lower solar panel 201 are opened and formed into a planar shape horizontally to the ground, the solar panel is not limited to horizontal because it is opened toward the radiation direction of sunlight. .

  As shown in FIG. 2, the solar panel system 1 according to the present embodiment is an upper stage member 100 positioned vertically above the ground in comparison with the lower stage member 200, and the upper stage member 100 when the solar panel system 1 is used. An upper end solar panel 101 for opening solar energy and an air space 102 vertically above the ground as compared to the lower member 200 are provided.

  In addition, the solar panel system 1 according to the present embodiment has the lower member 200 positioned lower in the vertical direction with respect to the ground compared to the upper member 100 and the end of the lower member 200 when using the solar panel system 1 The lower solar panel 201 is opened in the shape of a solar energy, and the space 202 is positioned vertically lower than the ground in comparison with the upper member 100.

  The upper stage space 102 is located substantially at the center in the vertical direction of the upper stage member 100 and at an outer end in the horizontal direction with respect to the ground. When the solar panel system 1 is used, the upper space 102 can accommodate the upper solar panel 101. The lower space 202 is located substantially at the center in the vertical direction of the lower member 200, at an outer end in the horizontal direction with respect to the ground. The lower space 202 enables the lower solar panel 201 to be stored.

  The structure of the upper-stage member of the solar panel system concerning this embodiment and its connection part, and an effect | action are demonstrated using FIG. 2, FIG. FIG. 3 is a view for explaining an upper stage member of the solar panel system according to the present embodiment according to the present embodiment. The solar panel system 1 according to the present embodiment shown in FIGS. 2 and 3 includes an upper stage member 100 and a lower stage member 200. The functions of the upper stage member 100 and the members of the lower stage member 200 are the same, and when the upper stage member 100 is described, a part of the description of the lower stage member 200 is omitted. Moreover, the structure and function which one solar panel and another solar panel have are the same.

  The upper stage member 100 includes the upper stage fixing portion 12 for fixing the upper stage solar panel 101 to the upper stage slide member 13, the upper stage slide member 13 for sliding the upper stage solar panel 101, and the four upper stage solar panels 101 as shaft members 30. It has an upper rotation member 15 for connecting and rotating the upper solar panel 101, and an upper slide fixing member 18 for fixing and releasing the slide of the upper solar panel 101.

  The upper fixing portion 12 fixes the upper solar panel 101 to the end of the upper slide member 13. The upper stage member 100 has the upper stage slide member 13 at the end, and the upper stage member 100 is connected to the shaft member 30, so the end of the upper solar panel 101 is formed at the end of the shaft member 30 . The upper slide member 13 is located between the two adjacent upper connection members 15.

  When the user of the solar panel system 1 opens the upper solar panel 101, the upper slide member 13 slides the upper solar panel 101 in the radiation direction of sunlight. Specifically, the upper solar panel 101 is slid by the upper slide member 13 from the center 10 in the direction opposite to the contraction direction. Thus, the upper solar panel 101 is stretched from the center 10 in the direction opposite to the contraction direction.

  The upper stage rotation member 15 is provided with an upper stage hinge pin 14. When the upper stage rotating member 15 is closed from the opened state of the upper stage solar panel 101, the upper stage solar panel has the upper stage hinge pin 14 provided on the upper stage rotating member 15 as a fulcrum and 16 provided on the upper stage rotating member 15 as the upper stage shaft 16. The shaft 101 is rotated in the extending direction beyond the end of the shaft member 30. The upper solar panel 101 is folded so as to close substantially vertically to the ground.

  The upper slide fixing means 18 has an upper stop 19 in the space 102. The upper slide fixing means 18 fixes the upper solar panel 101 in an open state when the upper solar panel 101 is slid by the upper slide member 13. The upper stage stop section 19 locks (locks) the tip of the upper stage slide fixing means 18. Specifically, in the upper slide fixing means 18, the upper solar panel 101 is slid by the upper slide member 13 in the direction opposite to the contraction direction from the center, and again the upper solar panel 101 is moved by the upper slide member 13 from the center When the slide member 13 slides in the contraction direction, the slide member 13 is fixed by the system stop of the upper stage stop portion 19. Thereby, the state where the upper solar panel 101 is opened is fixed.

  When the upper solar panel 101 is again slid in the contraction direction from the center by the upper slide member 13 and the slide member 13 is fixed in the slide by the upper stop of the upper stop 19, as described above, The tip portion is housed in the space 102. As a result, since the tip end portion is accommodated by the upper stage space 102, it is possible to prevent the middle solar panel 101 from falling inside.

  When the top end slide fixing means 18 stops the top end of the top slide fixing means 18 and the top solar panel 101 is fixed in the open state and is slid again, the top solar panel 101 is opposite to the contraction direction from the center. By being pulled to the side of the direction, the system stop of the system stop 19 is released, and the fixed state in which the upper solar panel 101 is open is released. When the fixation is released, the upper solar panel 101 can be slid by the upper slide means 13 back to the slidable state. In addition, since the fixing is released, the upper solar panel 101 can be rotated by the rotating member 15.

  Thus, each upper solar panel 101 is slid by the upper slide member 13 so as to extend outward from the center 10, and the upper slide fixing means 18 fixes the slide by the upper slide member 13. As a result, when the upper solar panel 101 is opened by the user of the solar panel system 1, the four upper solar panels 101 are opened in a plane when viewed as the entire upper member 100.

  In addition, when the upper solar panel 101 is closed by the user from the state of being opened in a plane, the upper solar slide fixing means 18 releases the fixation and the upper slide member 13 slides the center 10 from the center 10 in the radiation direction of sunlight. It is extended and rotated by the upper stage rotating member 15 to be closed. Thus, the upper solar panel 101 is folded.

  The configuration and operation of the lower member and the connecting portion thereof will be described with reference to FIGS. 3 and 9. FIG. 9 is a cross-sectional view of the back surface for explaining the lower member of the solar panel system according to the embodiment of the present invention. The lower member 200 also has the same configuration as the upper member 100. Lower solar panel 201 corresponding to upper solar panel 101, lower fixed portion 22 corresponding to upper fixed portion 12, lower slide member 23 corresponding to upper slide member 13, lower hinge pin 24 corresponding to upper hinge pin 14, upper rotation member 15 And the lower shaft 26 corresponding to the upper shaft 16, the lower slide fixing member 28 corresponding to the upper slide fixing member 18, and the lower system stop 29 corresponding to the upper system stop 19 respectively. It is a thing. About each composition of the above lower layer members 200, composition and correspondence are the same as that of upper layer members 100.

  As shown in FIG. 9, one lower solar panel 201 is disposed between the two upper solar panels 101 described with reference to FIG. , Formed in the gap between the four upper solar panels 101. Further, as shown in FIG. 9, the lower solar panels 201 are arranged orthogonally, and the intervals between the panels are even.

  The lower solar panel 201 is vertical to the ground with the lower hinge pin 24 provided in the lower rotating member 25 as a fulcrum and the 26 provided in the lower rotating member 25 as the lower shaft 26 when the lower solar panel 201 is closed from the opened state by the user. Rotate downward. That is, from the state in which the lower solar panel 201 is opened by the user, the lower solar panel 201 is closed so as to rotate toward the main body located inside the lower solar panel 201. Thus, the upper stage member 100 is provided with the upper stage rotation member 15 which is rotated in the extending direction ahead of the end portion of the shaft member 30 from the state where the upper stage solar panel 101 is opened planarly. With the configuration provided with the lower rotation member 25 for rotating the solar panel 201 in the direction toward the main body of the shaft member 30 from the state in which the solar panel 201 is opened planarly, all solar panels in the upper and lower stages can be compactly folded.

  In the present embodiment, the upper and lower members have a space, and the upper and lower solar panels are accommodated in the space. However, the space may be omitted. Even in such a case, the upper and lower solar panels are stably fixed because the slides are fixed by the upper and lower slide fixing members, so that the upper and lower solar panels are stably fixed. The slide is fixed on the Even in this case, each solar panel is not dropped to the ground or the like.

  The energy conversion efficiency and each component of the solar panel system according to the present embodiment will be described using FIGS. 4 and 8. FIG. 4 is a view showing each component when the panel is stored. FIG. 8 is a view showing a battery drawer according to an embodiment of the present invention.

  The solar panel system 1 concerning this embodiment is provided with the tripod 300 which is each component, and the battery 400 as an attachment part. As shown in FIG. 8, the battery 400 includes a USB 41 as a USB (Universal Serial Bus) terminal and a DC (Direct Current) 42 as a DC terminal as a power supply outlet. The tripod 300 is for stably holding the solar panel system 1 of the main body from the ground when the solar panel system 1 of the main body is used. The USB 41 is an interface that supplies power to terminals such as personal computers and mobile phones. The DC 42 is also an interface that enables power supply to external devices.

  The battery 400 is attached to the tripod 300 and can be connected to the upper and lower solar panels. The battery 400 can supply power from the module portion of the upper and lower solar panels to an external device through the USB 41 or the DC 42, and can charge the solar energy. Further, although the upper and lower members mentioned above are configured to open the upper and lower solar panels in the incident direction to the sunlight, the tripod 300 or the shaft member 30 part is made of the above-mentioned upper and lower members. You may provide the angle adjustment part which adjusts the angle which turns the incident direction to sunlight. Thereby, it can be adjusted to obtain the maximum output in accordance with the elevation angle with the sun. From the circumstances of Japan, the elevation angle is, for example, approximately 20 degrees to 40 degrees. For example, in Tokyo, it is preferable to set the elevation angle to 35 degrees on average. The angle adjustment unit enables installation in accordance with the amount of solar radiation.

  As described above, the solar panel according to the present embodiment includes the tripod 300 and the battery 400 as accessory parts, thereby supporting a large amount of electric energy and maintaining high conversion efficiency of solar energy.

  Next, the solar panel 101 according to the present embodiment will be described. The solar panel 101 has, for example, a length of 300 mmφ and a width of 60 mmφ. In this case, when the solar panel 101 is used, it has a length of 300 mmφ in the horizontal direction and a length of 60 mmφ in the depth direction. The module portion of the solar panel 101 is, for example, 282 mm in length and 52 mm in width. The portion other than the module portion of the solar panel 101 is protected by, for example, a PET resin laminate material. The laminate material is excellent in impact resistance, water resistance, and excellent in lightness.

  The effects that can be achieved by the solar panel system 1 according to the present embodiment will be described including conventional problems and solutions.

  Conventional common solar panels are low cost silicon cells are used. A single crystal cell is a low-cost device, but with 2, 5W x 8 sheets, the total output is about 20W, which is often the case of non-power. In addition, when trying to charge the mobile battery with a solar panel, the panel of 20W or less needs to be exposed to the sun for 8 hours or more, and the user says that it can not be charged in a day and it can not be put to practical use. The coming situation actually existed.

  Also, as a small electronic device such as a smartphone, it is equipped with an AC inverter called a portable battery on top of which the demand has been expanding in recent years, although the output is sufficient as the supply power to the power bank (charger) In 20W, it is not enough to supply power storage devices.

  In addition, in order to achieve folding and high output, it is necessary to adopt a solar panel with a conversion efficiency of 17% or more. However, when a solar panel is employed as in the present embodiment, for example, eight high-output modules can be used, and an output of 24W can be obtained with 3W × 8 sheets.

  In addition, as in this embodiment, a compact and portable solar panel with a high power of 24 W is not only a mobile power bank sold as a smartphone charger, but also a portable power that has recently expanded the market for industrial use With the number of W that can be used as a bank solar, there is a high possibility of expanding the market significantly, and the demand is extremely large.

  Furthermore, according to the solar panel of the present embodiment, since the solar panel according to the present embodiment is provided with the configuration having excellent flexibility, it is also used, for example, in non-expensive cases used for core parts such as disaster relief and emergency communication. There is a possibility. We can expect activity in such a field.

  The container which accommodates a solar panel and carrying are demonstrated using FIG. FIG. 5 is a view showing a container for storing a solar panel.

  The container 500 for the solar panel 101 includes a string 50 that allows the user to carry the solar panel 101 according to the present embodiment. The strap 50 can also be carried over the shoulder if it is possible for the user to carry the container 500 by hand. The container 500 concerning this embodiment is a cylindrical shape about 65 mm diameter x 600 mm (length), for example. This is, for example, the shape when the solar panel 101 is closed and stored.

  Moreover, the container 500 concerning this embodiment is a shape of the magnitude | size of about 600 mm diameter x 450 mm (height), for example including a tripod. Unlike the large drum can-shaped bag and the inconvenient carrying bag such as a suit bag, it has a convenient size. Thus, the solar panel system according to the present embodiment has portability while maintaining high conversion efficiency of solar energy.

  Further, according to the present embodiment, the solar panel system 1 of the main body has a shape in which each panel can be folded at the time of storage, and can accommodate the container 500 integrally with the shaft member, and the container 500 has a cylindrical shape. And the cord 50, it has the effect that it does not get in the way of the user's hands. In addition to responding to the outdoor needs which are increasing in recent years, it can also respond to emergency situations such as disasters. In the event of a disaster, both hands are not blocked, and other relief supplies can be carried and people can be helped while resting on their shoulders.

  Furthermore, according to the present embodiment, since the solar panel 101 has a waterproof function, it has convenience as an outdoor, for example, fishing, mountain, disaster prevention application.

  FIG. 6 is a first view showing a developed state of the solar panel system according to the embodiment of the present invention. The storage state of the solar panel system shown in FIG. 4 and FIG. 5 is expanded to actually receive and use sunlight, but the solar panel is attached to the leg shown in FIG. It is shown in FIG.
