[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figures 1 to 6 , the present invention provides a technical solution:

[0031] The user-side integrated photovoltaic and storage converter comprises a base 1, a storage box 2 is fixedly connected to the middle of the upper end surface of the base 1, and a storage compartment 22 is provided on the upper end surface of the storage box 2, the storage box 2 is hollow inside and is slidably connected to a drawer 21, a suspension mechanism 3 is provided on the upper side of the rear end surface of the storage box 2, and a limiting mechanism 4 is provided between the storage box 2 and the suspension mechanism 3, the suspension mechanism 3 is used to realize the suspension and fixed storage of the unit module, and the unit module can be supported in a plane and the tilt angle of the unit module can be adjusted, so as to facilitate observation by the user.

[0032] By adopting the above technical solution and adding a hanging mechanism 3 to the device, on the one hand, the unit module can be clamped and fixed by the clamping assembly 32 in the hanging mechanism 3, and fixed and stored in a hanging manner to avoid being close to or in contact with the ground and being affected by the humid air on the ground. At the same time, compared with the existing cabinet storage method, it is more conducive to ventilation and drying, and reduces the impact of moisture on the unit module.

[0033] As an embodiment of the present invention, Figure 1 and Figure 2 As shown, the suspension mechanism 3 includes a strong magnet 31, a clamping assembly 32, and a suspension plate 33. The number of the suspension plates 33 is at least five groups, and they are horizontally distributed. The adjacent surfaces of the adjacent suspension plates 33 are embedded with strong magnets 31 and fixed by magnetic attraction. The middle part of the upper end surface of the suspension plate 33 is fixedly connected with a clamping assembly 32. The five groups of suspension plates 33 have the same structure and the same size.

[0034] By adopting the above technical solution, when the clamping component 32 in the suspension mechanism 3 supports the clamping unit module, based on the above embodiment, the clamping component 32 in the suspension plate 33 at the specified position is flipped upward, and the unit module is fixed by suspending the clamping component 32 again, so that the unit module can be supported, and then the adjacent suspension plates 33 are fixed by magnetic adsorption of the strong magnet 31 to make them level, so that the user can observe the unit module for maintenance.

[0035] As an embodiment of the present invention, Figure 1 and Figure 2 As shown, the suspension plate 33 is made of transparent polyethylene material, and the strong magnet 31 is designed in a strip structure and is horizontally consistent with the side plate of the suspension plate 33 and has the same length.

[0036] By adopting the above technical solution, the strong magnet 31 with a strip structure design and aligned with the side plate of the suspension plate 33 can fix the adjacent suspension plate 33 with magnetic force over the maximum area, and the suspension plate 33 made of transparent polyethylene material can facilitate the user to observe the name and other identification of the unit module on the clamping assembly through the suspension plate 33 from top to bottom during the process of hanging and storing the unit module, so that the user can pick up the unit module of the suspension plate 33 at the designated position.

[0037] As an embodiment of the present invention, Figure 2 and Figure 3 As shown, the clamping assembly 32 includes clamping plates 325 symmetrically distributed and fixed on the suspension plate 33, and adjacent surfaces of the two clamping plates 325 are provided with movable grooves 321, and the internal movably connected of the movable grooves 321 are connected with an adjusting plate 323, and the internal movably connected of the two clamping plates 325 are connected with two extrusion plates 328, and a plurality of springs 322 are symmetrically distributed between the extrusion plate 328 and the adjusting plate 323, and one end of the spring 322 is fixed to the adjusting plate 323, and the other end is fixed to the extrusion plate 328.

[0038] By adopting the above technical solution, when in use, the user inserts the unit module between the two extrusion plates 328, and the extrusion plate 328 further compresses the spring 322 toward the outer end, and utilizes the elastic compression of the spring 322 to reversely extrude the unit module, thereby clamping and fixing the unit module, so that the suspension plate 33 can suspend and store the unit module.

[0039] As an embodiment of the present invention, Figure 2 and Figure 3 As shown, a threaded airbag 326 is glued and fixed between the extrusion plate 328 and the adjustment plate 323, and the threaded airbag 326 is located between the upper and lower springs 322. The extrusion plate 328 is designed as a hollow structure, and anti-slip bumps are provided on adjacent surfaces. The air holes of the threaded airbag 326 are located on one side of the extrusion plate 328.

[0040] By adopting the above technical solution and based on the above embodiment, when the unit module is inserted between the extrusion plates 328, the extrusion plates 328 are displaced outward, and while further squeezing the spring 322, the threaded airbag 326 is simultaneously squeezed. At this time, the gas inside the threaded airbag 326 is compressed and ejected from the air hole. The gas passes through the hollow structure of the extrusion plate 328 and blows between adjacent extrusion plates 328 to clean up any debris or dust that may exist therein. Anti-slip bumps are designed on the adjacent extrusion plates 328 to further increase the friction resistance between the extrusion plates 328 and the unit module, thereby increasing the fixing effect.

[0041] As an embodiment of the present invention, Figure 2 and Figure 3As shown, the upper end of the extrusion plate 328 is fixedly connected with an inclined plate 327, and two groups of inclined plates 327 are relatively distributed, and the inclined plates 327 are made of elastic metal.

[0042] By adopting the above technical solution, the elastic metal inclined plate 327 can not only serve as a guide when the unit module is inserted between the extrusion plates 328, making it easier for the user to plug and fix it, but also, when the suspension plate 33 is flipped and the clamping assembly 32 is upward, the inclined plate 327 can also serve as a support plate to support and fix the disassembled shell of the unit module or the unit module body.

[0043] As an embodiment of the present invention, Figure 2 and Figure 3 As shown, bolts 324 are threadedly connected to both sides of the clamping plate 325 , and one end of the bolt 324 extends into the movable groove 321 and abuts against the fixed movable groove 321 . The opening width of the movable groove 321 is smaller than the width of the adjustment plate 323 .

[0044] By adopting the above technical solution, the spring 322 is repeatedly squeezed, expanded and contracted, and its elastic deformation may be damaged, resulting in a reduction in the squeezing force on the squeezing plate 328. At this time, the user can rotate the bolt 324 to press the inner side of the clamping plate 325 against the movable plate, thereby adjusting the elastic deformation capacity of the spring 322 and increasing the fixing effect of the clamping unit module.

[0045] As an embodiment of the present invention, Figure 4 and Figure 5 as well as Figure 6 As shown, the limiting mechanism 4 includes a rotating shaft 41, an ear plate 42, an electromagnet 43, a fixed plate 44, a slider and a slide groove 45. The lower end of the five groups of hanging plates 33 is provided with a rotating shaft 41, and the hanging plate 33 is rotatably connected to the rotating shaft 41 through a rotating shaft. Ear plates 42 are fixed on both sides of the storage box 2. The two ends of the rotating shaft 41 respectively penetrate the ear plates 42 and are rotatably connected to the ear plates 42. The side of the ear plate 42 is fixedly connected with an annular electromagnet 43, and the annular electromagnet The magnet 43 is sleeved on the outer surface of the rotating shaft 41 without contacting the rotating shaft 41. A fixed disk 44 is provided on one side of the electromagnet 43, and the fixed disk 44 is adjusted on the outer surface of the rotating shaft 41. A slider and a slide groove are provided between the fixed disk 44 and the rotating shaft 41, and the slide groove is three groups of rings equidistantly opened on the outer surface of the rotating shaft 41. The slider is located inside the slide groove and is slidably connected, and the other end of the slider is fixed to the inner surface of the fixed disk 44, and the adjacent surfaces of the fixed disk 44 and the electromagnet 43 are glued with rubber pads.

[0046] By adopting the above technical scheme and based on the above embodiment, the rotating shaft between the suspension plate 33 and the rotating shaft 41 is rotated to rotate the plane of the rotating suspension plate 33 upward. When the unit module is placed flat on the suspension plate 33, the user adjusts the inclination angle between the suspension plate 33 and the storage box 2 by pushing the suspension plate 33 upward or downward and utilizing the rotating connection between the rotating shaft 41 and the ear plate 42. After the adjustment is completed, the electromagnet 43 is controlled to conduct electricity to generate magnetic force to adsorb the fixed plate 44 located on the rotating shaft 41. The fixed plate 44 is further connected to the sliding groove by the slider and moves toward the direction of the electromagnet 43, thereby magnetically fixing the fixed plate 44. At this time, the fixed plate 44 is pressed against the inner wall of the sliding groove through the slider to limit the rotation angle of the rotating shaft 41, thereby further limiting the angle of the suspension plate 33 and realizing the limitation of the inclination angle of the unit module.

[0047] Working principle: When in use, the user inserts the unit module between the extrusion plates 328 through the elastic metal inclined plate 327 to guide it. When inserted between the two extrusion plates 328, the extrusion plate 328 moves to the outside and further compresses the spring 322. The elastic compression of the spring 322 is used to reversely extrude the unit module to achieve clamping and fixing of the unit module, so that the hanging plate 33 can hang and store the unit module. When the unit module is inserted between the extrusion plates 328, the extrusion plate 328 moves to the outside and while further squeezing the spring 322, it also squeezes the threaded airbag 326. At this time, the gas inside the threaded airbag 326 is compressed and ejected from the air hole. The gas passes through the extrusion plate 328 with a hollow structure and blows between the adjacent extrusion plates 328. The debris or dust that may exist therein is cleaned, and the anti-skid protrusions are designed on the adjacent surface extrusion plates 328 to further increase the friction resistance between the extrusion plates 328 and the unit modules, thereby increasing the fixing effect. By adding a hanging mechanism 3 to the device, on the one hand, the unit modules can be clamped and fixed by the clamping components 32 in the hanging mechanism 3, and fixed and stored in a hanging manner to avoid being close to or in contact with the ground and being affected by the humid air on the ground. At the same time, compared with the existing cabinet storage method, it is more conducive to ventilation and drying, and reduces the influence of moisture on the unit modules; on the other hand, when teaching is needed, the clamping components 32 in the hanging plate 33 at the designated position are flipped upward, and the unit modules are fixed by hanging the clamping components 32 again, so that the unit modules can be supported, which is convenient for users to observe and maintain the unit modules;

[0048] By rotating the rotating shaft between the hanging plate 33 and the rotating shaft 41, the rotating hanging plate 33 is turned upward. When the unit module is placed flat on the hanging plate 33, the user can adjust the inclination angle between the hanging plate 33 and the storage box 2 by pushing the hanging plate 33 upward or downward, and use the rotating shaft 41 and the ear plate 42 to rotate and connect. After the adjustment is completed, the electromagnet 43 is controlled to conduct electricity to generate a magnetic force to adsorb the fixed plate 44 located on the rotating shaft 41. The fixed plate 44 is further connected to the sliding groove by the slider to move in the direction of the electromagnet 43, and then the fixed plate 44 is magnetically fixed. At this time, the fixed plate 44 is pressed against the inner wall of the sliding groove through the slider to limit the rotation angle of the rotating shaft 41, thereby further limiting the angle of the hanging plate 33 and realizing the limitation of the inclination angle of the unit module. By adding a limiting mechanism 4 to the device, the inclination angle between the hanging plate 33 and the storage box 2 can be further adjusted when the clamping assembly 32 in the hanging mechanism 3 supports the unit module, thereby adjusting the angle of the unit module, which is convenient for teaching to adjust the inclination angle of the unit module according to personal needs and improve the use efficiency of the device.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
