Description

Technical Field

[0001] The utility model belongs to the field of photovoltaics, and specifically relates to a foldable photovoltaic module. Background Art

[0002] In the prior art, the foldable photovoltaic module is in a flat-laying mode, which affects the lighting area. At the same time, there are generally problems such as cumbersome folding and unfolding processes and easy loosening during folding and storage.

[0003] A foldable photovoltaic module disclosed in a Chinese patent (CN115549565A). When the photovoltaic panel is folded and placed, the photovoltaic panel includes a first photovoltaic panel, a second photovoltaic panel, a third photovoltaic panel, a fourth photovoltaic panel, and a fifth photovoltaic panel from top to bottom in sequence. One end of the first photovoltaic panel is movably connected to one end of the fifth photovoltaic panel, and the first photovoltaic panel and the fifth photovoltaic panel serve as the top and bottom of the photovoltaic panel respectively, and the second photovoltaic panel, the third photovoltaic panel, and the fourth photovoltaic panel are received in the internal space formed by the first photovoltaic panel and the fifth photovoltaic panel; the other end of the first photovoltaic panel is movably connected to one end of the second photovoltaic panel; the other end of the fifth photovoltaic panel is movably connected to one end of the third photovoltaic panel, and the fourth photovoltaic panel is received in the internal space formed by the fifth photovoltaic panel and the third photovoltaic panel; the other end of the third photovoltaic panel is movably connected to one end of the fourth photovoltaic panel. When the photovoltaic panel is unfolded, the first photovoltaic panel rotates and unfolds first, then the second photovoltaic panel unfolds, then the third photovoltaic panel rotates and unfolds, and finally the fourth photovoltaic panel rotates and unfolds, thus completing the full unfolding of the photovoltaic panel.

[0004] In the prior art, the unfolding of the foldable photovoltaic panel mostly adopts a head-to-tail connection method for unfolding. This unfolding method will cause too large a span, resulting in the photovoltaic panel shaking when the wind pushes the photovoltaic panel during use, thus loosening the connection. Summary of the Utility Model

[0005] To solve the above problems, the utility model adopts the following technical solutions.

[0006] A foldable photovoltaic module includes a support rod. A cross link is welded to the end of the support rod. Hinge joints are pin-connected to the four sides of the cross link. A connecting column is integrally connected to the outer end of the hinge joint. A pair of second connecting rings are movably sleeved on the connecting column. A photovoltaic panel is connected to each side of the pair of second connecting rings. The pair of photovoltaic panels slidably sleeved on the same connecting column by the second connecting rings can be folded with each other by rotation.

[0007] A first connecting ring is fixedly connected to the opposite side of the photovoltaic panel. The photovoltaic panels sleeved on two adjacent connecting columns are parallel and adjacent. The positions of the first connecting rings on the adjacent photovoltaic panels are staggered front and back, and the first connecting rings are concentric circles. A pin is inserted into the first connecting ring.

[0008] A protruding connecting piece is provided on the lower surface of the latch pin, a connecting rod is pinned on the connecting piece, a movable sleeve is movably sleeved on the support rod, a plurality of connecting ears are equidistantly arranged on the movable sleeve in a surrounding manner, and the end of the connecting rod is pinned on the connecting ear.

[0009] When the movable sleeve moves downward on the support rod, it drives the connecting rod to move downward synchronously. The connecting rod pulls the opposite sides of the adjacent photovoltaic panels toward the support rod, and the other end of the photovoltaic panel pulls the connecting column toward the support rod, so that the whole device is folded and folded.

[0010] The photovoltaic panel is a right-angled triangle structure, and two adjacent photovoltaic panels form an isosceles triangle structure.

[0011] A thread is engraved on the support rod, and a nut is movably sleeved on the support rod. When the movable sleeve moves upward on the support rod to unfold the reclining plate, the nut and the thread are connected to resist the movable sleeve.

[0012] A plurality of photovoltaic panels form a rectangular structure, and four sides of the cross connecting rod overlap with the diagonal lines of the rectangular photovoltaic panels.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The present application utilizes a support structure similar to an umbrella to connect multiple photovoltaic panels. When the support is pushed to unfold, the photovoltaic panels installed on the support will unfold, so that the photovoltaic panels can receive solar radiation in a more favorable state. The support with an umbrella structure can change the state of the photovoltaic panels to achieve the effect of unfolding and folding, making the photovoltaic panels easy to carry in a folded state.

[0015] In the present application, the first connecting ring can be locked by the provided thread and the sleeve nut to prevent the first connecting ring from returning to the initial position due to the pressure of the photovoltaic device, thereby preventing the photovoltaic device from suddenly changing from an expanded state to a collapsed state due to the return of the first connecting ring during use, and preventing the photovoltaic device from being damaged due to sudden shaking in the process.

[0016] In the present application, the light-receiving surface of the folding photovoltaic module is still on the outer surface after being folded. Unlike traditional folding photovoltaic modules, the light-receiving surface is easily worn due to friction due to folding, which greatly reduces the luminous efficiency or causes damage to the photovoltaic module.

[0017] Meanwhile, since the present application adopts an umbrella-shaped structure that can be folded and retracted, when used outdoors, in the event of strong convection and windy weather, the foldable photovoltaic module in the present application can be folded and retracted, thereby reducing the windward area and reducing the damage to the photovoltaic module in bad weather. After the bad weather has passed, the photovoltaic module can be unfolded and can still be used normally. Due to the adoption of the umbrella structure, the folding and unfolding of the photovoltaic module are relatively convenient, and the problem of photovoltaic damage caused by difficult operation can be reduced when dealing with bad weather.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the following detailed description of the specific embodiments of the present utility model will be given in conjunction with the drawings of the specification.

[0026] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0027] Secondly, the so-called "one embodiment" or "embodiment" herein refers to specific features, structures or characteristics that may be included in at least one implementation manner of the present utility model. The "in one embodiment" that appears in different places in this specification does not all refer to the same embodiment, nor is it an individual or alternative embodiment that is mutually exclusive with other embodiments. The present utility model provides the following embodiments.

[0028] Please refer to Figures 1-5 , a foldable photovoltaic module, including a support rod 101. The support rod 101 belongs to basic accessories for connecting solar panels and assembling the solar panels on other devices. A cross link 104 is welded to the end of the support rod 101. The cross link 104 belongs to a hinge part mainly used for connecting the connecting parts of the foldable photovoltaic module. Hinge joints 104a are pin-connected to the four sides of the cross link 104. A connecting column 104a-1 is integrally connected to the outer end of the hinge joint 104a. The connecting column 104a-1 is the connecting part of the foldable photovoltaic module for connecting individual photovoltaic plates. A pair of second connecting rings 104a-2 are movably sleeved on the connecting column 104a-1, and a photovoltaic panel 105 is connected to each side of the pair of second connecting rings 104a-2. The pair of photovoltaic panels 105 slidably sleeved on the same connecting column 104a-1 by using the second connecting rings 104a-2 can be folded with each other by rotation.

[0029] In Figures 1-5In this case, since the cross-link 104 has four sides, there are also four connecting columns 104a-1 connected by the cross-link 104. Two photovoltaic panels 105 connected by a pair of second connecting rings 104a-2 on one connecting column 104a-1 need to be connected to the photovoltaic panels 105 on other connecting columns 104a-1 in order to be folded or unfolded synchronously. Therefore, a first connecting ring 103a-1 is fixedly connected to the opposite side of the photovoltaic panel 105. The photovoltaic panels 105 sleeved on two adjacent connecting columns 104a-1 are parallel and adjacent, and the positions of the first connecting rings 103a-1 on the adjacent photovoltaic panels 105 are staggered front and back, and the first connecting rings 103a-1 are concentric circles. An insertion pin 103a is inserted into the first connecting ring 103a-1, and the insertion pin 103a and the first connecting ring 103a-1 are used to connect the photovoltaic panels 105 that are adjacent but not on the same connecting column 104a-1 without affecting the rotation of the adjacent photovoltaic panels 105; further, all the photovoltaic panels 105 are connected to each other. Therefore, a driving mechanism is also required to control the folding and unfolding of all the photovoltaic panels 105. Therefore, a protruding connecting piece is provided on the lower surface of the insertion pin 103a, a connecting rod 103 is pinned on the connecting piece, a movable sleeve 102 is movably sleeved on the support rod 101, and a plurality of connecting ears 102a are arranged on the movable sleeve 102 at equal intervals in a surrounding manner, and the end of the connecting rod 103 is pinned on the connecting ear 102a. When the movable sleeve 102 moves downward on the support rod 101, it drives the connecting rod 103 to move downward synchronously. The connecting rod 103 pulls the opposite side edges of the adjacent photovoltaic panels 105 towards the support rod 101, and the other end of the photovoltaic panel 105 pulls the connecting column 104a-1 towards the support rod 101 as well, so that the entire device is folded and retracted.

[0030] In Figure 4 In this case, in order to make the folding and unfolding more convenient, the photovoltaic panel 105 is a right triangle structure, and two adjacent photovoltaic panels 105 form an isosceles triangle structure. A plurality of photovoltaic panels 105 form a rectangular structure, and the four sides of the cross-link 104 overlap with the diagonals of the rectangular photovoltaic panels 105, so that the present application will not be resisted during folding or unfolding, and the photovoltaic panels 105 move synchronously.

[0031] In Figure 2 In this case, in order to fix the movable sleeve 102 so that the movable sleeve 102 will not slide downward on the support rod 101 due to the weight of the photovoltaic panel 105 and other reasons and cause the unfolded photovoltaic panel 105 to suddenly retract when the movable sleeve 102 moves upward on the support rod 101, threads are engraved on the support rod 101, and a nut is also movably sleeved on the support rod 101. When the movable sleeve 102 moves upward on the support rod 101 to unfold the photovoltaic panel 105, the nut is used to abut against the movable sleeve 102 by means of the threaded connection, thereby fixing the position of the movable sleeve 102.

[0032] The above content further elaborates on the present utility model in combination with specific embodiments. It cannot be determined that the specific implementation of the present utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model pertains, without departing from the concept of the present utility model, several simple deductions or substitutions can still be made, and all should be regarded as falling within the protection scope determined by the claims submitted for the present utility model.
