DETAILED DESCRIPTION

[0018] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0019] First embodiment

[0020] like Figure 6-Figure 9 As shown, the compact packaging structure suitable for lightweight photovoltaic modules according to the first embodiment of the present invention includes: Base 1; Two positioning components 2, the two positioning components 2 are distributed along a first horizontal direction directly above the base 1, each positioning component 2 includes a positioning protrusion 201 and a positioning groove 202 that are spaced apart along a second horizontal direction and extend along a vertical direction, the first direction and the second direction are perpendicular to each other, and the positioning protrusion 201 of one positioning component 2 is arranged opposite to the groove of the other positioning component 2, so as to clamp two photovoltaic components 4 that are opposite to each other and have opposite light-receiving surfaces from both ends; The packaging component 3 is used to enclose with the base 1 to form a packaging cavity, and the two positioning components 2 are arranged in the packaging cavity.

[0021] Specifically, the base 1 is a double-layer plate structure, both layers of the plates are wooden boards and are fixedly connected by support blocks, which ensures the structural strength of the base 1 and facilitates the insertion of forklift pins so that multiple photovoltaic modules 4 can be placed on the base 1 for transportation and movement. The base 1 is horizontally arranged, and its projection on the horizontal plane is a rectangle. The length direction of the rectangle is the first direction, and the width direction is the second direction.

[0022] Two positioning components 2 arranged opposite to each other along the first direction are fixed directly above the base 1, and the positioning components 2 include a positioning strip 203 extending along the second direction. Positioning protrusions 201 and positioning grooves 202 are arranged on opposite surfaces of the two positioning strips 203. Specifically, the widths of the two opposite side surfaces of the positioning protrusion 201 (hereinafter referred to as the width of the positioning protrusion 201) and the widths of the two opposite side surfaces of the positioning groove 202 (hereinafter referred to as the width of the positioning groove 202) are consistent, and both are twice the height of the frame profile 42 in the photovoltaic component 4 (it should be noted that the height of the frame profile 42 in the photovoltaic component 4 refers to the size of the frame profile 42 in the vertical direction when the photovoltaic component 4 is placed flat). Further preferably, the positioning protrusion 201 and the positioning groove 202 are integrally formed on the positioning strip 203, and the positioning strip 203 is preferably made of a material with certain structural strength and elasticity so as to be able to deform appropriately, such as foam or foam. The foam is preferably EVA foam. On the basis of taking into account structural strength and being able to deform appropriately, the material is lightweight, which reduces the weight after placing a batch of photovoltaic components 4 and facilitates transportation.

[0023] After adopting the above structure, two photovoltaic modules 4 facing each other and having opposite light-receiving surfaces can be inserted between the facing positioning protrusions 201 and positioning grooves 202 in the two positioning components 2 from top to bottom, so that one of the longer side walls of the photovoltaic module 4 is adjacent to the top of the base 1, and the two ends are respectively facing the end face of the positioning protrusion 201 and the inner bottom wall of the positioning groove 202. In the above manner, two photovoltaic modules 4 are grouped as a group and placed in sequence between the facing positioning protrusions 201 and positioning grooves 202 of the two positioning components 2, so that the wire box 43 and the connector 44 on the backlight side of the photovoltaic module 4 are staggered, and each photovoltaic module 4 is adjacent in sequence, which not only increases the overall storage capacity of the photovoltaic modules 4 of the packaging structure, but also enables large quantities of photovoltaic modules 4 to be stored. At the same time, each photovoltaic module 4 is arranged adjacent in sequence, which increases the strength of the packaging structure.

[0024] It should be noted that the structure in which two photovoltaic modules 4 are facing each other and the light-receiving surfaces are opposite to each other is as follows: Figure 4 and Figure 5As shown, when two photovoltaic modules 4 form a group, the light-receiving surfaces of the two photovoltaic modules 4 are opposite to each other, and the backlight surfaces are arranged opposite to each other, and the wire box 43 and the connector 44 on the backlight surface are located on the outside. Due to the presence of the positioning protrusion 201 and the positioning groove 202, when two adjacent groups of photovoltaic modules 4 are placed, the wire box 43 and the connector 44 located between the two groups of photovoltaic modules 4 can be staggered, thereby saving storage space for storing more photovoltaic modules 4.

[0025] After multiple groups of photovoltaic components 4 are inserted between the two positioning components 2, they are packaged on top of the base 1 through the packaging component 3, so that the packaging component 3 and the base 1 are enclosed to form a packaging cavity to protect the photovoltaic components 4 stored in batches between the two positioning components 2.

[0026] A further improvement is that the packaging component 3 includes an enclosing frame 31 extending in the vertical direction and a cover plate 32 covering the top of the enclosing frame 31, two U-shaped frames 11 facing each other are fixed above the base 1, and the two positioning components 2 are respectively fixed on the inner walls of the two U-shaped frames 11, and the outer side walls of the two U-shaped frames 11 are sealed and fitted with the circumferential inner wall of the enclosing frame 31.

[0027] Specifically, the projections of the two U-shaped frames 11 on the horizontal plane are U-shaped. The two U-shaped frames 11 are arranged opposite to each other along the first direction and are adjacent to the two ends of the base 1. A horizontal bottom plate 111 is fixed to the bottom of the U-shaped frame 11, and the bottom plate 111 is fixed to the top surface of the base 1.

[0028] In order to support the bottom of the photovoltaic components 4 placed in batches, a bottom pad 12 is arranged above the bottom plate 111 and between the two U-shaped frames 11. The bottom pad 12 is distributed side by side in the first direction and extends in the second direction. The material of the bottom pad 12 is consistent with the material of the positioning strip 203, so that after the photovoltaic component 4 is inserted between the positioning protrusion 201 and the positioning groove 202, the bottom of the photovoltaic component 4 is supported by the bottom plate 111 and the bottom pad 12, and a certain gap is left between the bottom of the photovoltaic component 4 and the top surface of the base 1, so that after the photovoltaic component 4 is placed, the binding belt 45 is inserted into the above-mentioned gap, and the two ends of the binding belt 45 are hot-melt connected together to form a closed loop while binding each photovoltaic component 4 together, thereby improving the overall packaging structure strength.

[0029] The positioning bars 203 are fixed on the inner bottom wall of the U-shaped frame 11, and there are two of them distributed along the vertical direction to ensure the positioning effect of the photovoltaic component 4, so that the light-receiving surface of the photovoltaic component 4 is perpendicular to the top surface of the base 1, avoiding the photovoltaic component 4 from being tilted after being placed between the positioning protrusion 201 and the positioning groove 202.

[0030] The enclosing frame 31 is arranged vertically. The enclosing frame 31 can be made of a plastic frame or a cardboard frame. The cover plate 32 is preferably made of a wooden board. In order to further reduce the weight, the cover plate 32 is in the shape of an "8" as a whole. A top pad 334 is fixedly connected to the bottom of the cover plate 32. The material of the top pad 334 is the same as that of the positioning strip 203. The circumferential outer edge of the top pad 334 is sealed and fitted with the circumferential inner wall of the top of the enclosing frame 31 to ensure that the cover plate 32 accurately covers the top of the enclosing frame 31; the bottom surface of the top pad 334 is fitted with the top of the photovoltaic module 4, so that it is convenient to place another layer of the photovoltaic module 4 on top of the cover plate 32. Figure 6 The packaging structure shown is convenient for storage and transportation.

[0031] Second embodiment

[0032] like Figure 10-Figure 21 As shown, the second embodiment of the present invention is suitable for a compact packaging structure of lightweight photovoltaic components. It is based on the first embodiment, but differs in that: the packaging component 3 includes two packaging units 33 arranged opposite to each other along the second direction, the two packaging units 33 both include a packaging groove 331, one end of the packaging groove 331 is provided with a sealing cover 332, and the other end is rotatably connected to the base 1 and the rotation axis extends along the first direction, the packaging component 3 also includes a fastening unit 34, the fastening unit 34 is used to lock and connect the packaging grooves 331 of the two packaging units 33, and in the locked state, the packaging grooves 331 of the two packaging units 33 both extend in the vertical direction and the grooves are arranged opposite to each other.

[0033] Compared with the first embodiment, after the packaging component 3 adopts the above structure, it always maintains a connection relationship with the base 1. When packaging, there is no need to put the enclosing frame 31 on the U-shaped frame 11 from top to bottom above the photovoltaic component 4, and then cover the cover 32. It is only necessary to rotate the two packaging grooves 331 and then lock the two packaging grooves 331 together; when taking out the photovoltaic component 4, it is only necessary to unlock the two packaging grooves 331 and rotate the packaging groove 331 to take out the photovoltaic component 4. There is no need to remove the cover 32 and the enclosing frame 31. The operation is more convenient and conducive to rapid packaging.

[0034] A further improvement is that the fastening unit 34 includes a fastening bolt 341 and a fastening nut 342 which are threadedly connected, and a fastening sleeve 343 is fixedly connected to the packaging groove 331. In the locked state, the fastening bolt 341 is inserted into the inner side of the fastening sleeve 343.

[0035] Specifically, the length of the packaging groove 331 is slightly larger than the width of the photovoltaic module 4, and the groove width is consistent with the length of the base 1. One end of the packaging groove 331 is rotated on the side of the upper plate of the base 1, and a cover 332 is fixed to the other end. The length of the cover 332 is consistent with the length of the base 1, and the width is half of the width of the base 1. The fastening unit 34 is arranged on the two outer walls of the packaging groove 331. The fastening unit 34 includes a fastening sleeve 343 fixedly connected to the outer wall of the packaging groove 331 and extending in the depth direction of the packaging groove 331, as well as a threaded fastening bolt 341 and a fastening nut 342; side pads 333 are fixed on the inner walls of both sides of the packaging groove 331, and a top pad 334 is fixed on the side of the cover 332 adjacent to the base 1. The materials of the side pads 333 and the top pad 334 are the same as the materials of the positioning strip 203 in the first embodiment.

[0036] After adopting the above structure, before use, the two packaging slots 331 are rotated to Fig.11 As shown in the position, the top of the base 1 is exposed. Fig.10 As shown, a plurality of photovoltaic modules 4 are placed between two positioning modules 2 on the base 1, and then, as shown in FIG. Fig.11 As shown, the packaging slot 331 is rotated to Fig.12 The two packaging grooves 331 are in the position shown in the figure. At this time, the two covers 332 are fitted together, the notches of the packaging grooves 331 are facing each other and the ends of the side walls are fitted together, so that the base 1, the two covers 332 and the two packaging grooves 331 are enclosed to form a packaging cavity to protect the photovoltaic components 4 inside, and then the two packaging grooves 331 can be locked and connected by the fastening unit 34. When locked and connected, the fastening sleeves 343 on the outer side walls of the two packaging grooves 331 are coaxial, and the inner diameter of the fastening sleeve 343 is consistent with the outer diameter of the fastening nut 342. After the rod of the fastening nut 342 passes through the two fastening sleeves 343, the fastening nut 342 is screwed in, and the two packaging grooves 331 can be fastened and connected.

[0037] After the locking is completed, the top pad 334 and the side pad 333 are in contact with the top and end of the photovoltaic module 4 respectively, connecting the base 1, the packaging groove 331, the cover 332 and the photovoltaic module 4 into one body, bearing the force together, and increasing the structural strength.

[0038] When the photovoltaic component 4 is needed, unscrew the fastening nut 342, detach the fastening bolt 341 from the two fastening sleeves 343, and then rotate the two packaging grooves 331 downward to expose the base 1. Then, the photovoltaic component 4 can be taken out from between the two positioning components 2, which is more convenient, faster and labor-saving.

[0039] A further improvement is that, in each positioning assembly 2, the distance between the two opposite outer side walls of the positioning protrusion 201 and the distance between the two opposite inner side walls of the positioning groove 202 are adjustable.

[0040] Since the width dimensions of the positioning protrusion 201 and the width dimensions of the positioning groove 202 are both adjustable, the width dimensions of the positioning protrusion 201 and the positioning groove 202 can be pre-enlarged during use so that the two are larger than twice the width dimension of the frame profile 42 of the photovoltaic component 4, so that the photovoltaic component 4 can be inserted between the positioning protrusion 201 and the positioning groove 202, and then the width dimensions of the positioning protrusion 201 and the positioning groove 202 can be reduced so that the widths of the positioning protrusion 201 and the positioning groove 202 are both equal to twice the frame profile 42 of the photovoltaic component 4, thereby ensuring that each photovoltaic component 4 is closely attached in sequence. In this way, on the one hand, the packaging structure is more compact, thereby increasing the storage capacity and ensuring the structural strength. On the other hand, since the width dimensions of the positioning protrusion 201 and the positioning groove 202 are both adjustable, they can be suitable for photovoltaic components 4 with frame profiles 42 of different height dimensions. Compared with the positioning protrusion 201 and the positioning groove 202 of the first embodiment, the packaging structure of this embodiment has a wider range of applications.

[0041] A further improvement is that each positioning component 2 includes positioning pieces 21 that are equally spaced along the second direction, the length direction of the positioning pieces 21 is the vertical direction, the width direction is the first direction, and the thickness direction is the second direction. A side of each positioning piece 21 adjacent to the corresponding end of the base 1 is located in the same vertical plane. Among any three adjacent positioning pieces 21, the width of the positioning piece 21 located in the middle is consistent with the width of the positioning piece 21 at one end, and is greater than or less than the width of the positioning piece 21 at the other end. The positioning component 2 also includes a distance adjusting unit, which is used to adjust the distribution interval of two adjacent positioning pieces 21.

[0042] Specifically, Fig.13 , Fig.14 , Fig.16 and Fig.18As shown, the positioning assembly 2 includes a plurality of positioning pieces 21 that are equally spaced along the second direction and arranged along the vertical direction. The side of the positioning piece 21 that is close to the end of the base 1 is located in the same vertical plane. The number of the positioning pieces 21 is an integer multiple of two. Two positioning pieces 21 with the same width size form a group. The positioning pieces 21 have two width sizes, wherein the width of the wider positioning piece 21 is twice the width of the narrower positioning piece 21. In this way, the wider group of positioning pieces 21 forms a positioning protrusion 201 between the two adjacent groups of narrower positioning pieces 21, and correspondingly, the narrower group of positioning pieces 21 forms a positioning protrusion 201 between the adjacent two groups of narrower positioning pieces 21. A positioning groove 202 is formed between the two wider positioning pieces 21, so that among the positioning pieces 21 of the positioning component 2, among any three adjacent positioning pieces 21 distributed along the second direction, the positioning piece 21 located in the middle position must have the same width as one of the remaining two positioning pieces 21. The distribution interval of two adjacent positioning pieces 21 is changed by the distance adjustment unit, so that the width dimensions of the positioning protrusion 201 and the positioning groove 202 can be changed, so that they are suitable for frame profiles 42 of photovoltaic components 4 with different heights, and the compactness and strength of the structure are ensured, while the storage capacity is increased.

[0043] A further improvement is that the distance adjustment unit is arranged on the side of the positioning groove 202 facing away from its own notch, and the distance adjustment unit includes a telescopic unit 22 arranged on the base 1, an extrusion bar 23 connected to the output end of the telescopic unit 22 and moving along the first direction, and a connecting rod 24 arranged between each two adjacent positioning pieces 21 and hinged to each other, the extrusion bar 23 extends along the second direction and abuts against at least two positioning pieces 21, and the adjacent positioning pieces 21 are relatively slidably connected along the second direction; the connecting rod 24 between the adjacent positioning pieces 21 is hinged through a connecting seat 241, and the connecting seat 241 is fixedly connected with a sliding frame 242, and the distance adjustment unit also includes a distance adjustment frame 25, the telescopic unit 22 is arranged on the base 1 through the distance adjustment frame 25, and the distance adjustment frame 25 includes a slide bar 251 extending along the second direction, and the slide bar 251 is connected to one of the slide bars 251. The sliding frame 242 is fixedly connected and slidably cooperates with the remaining sliding frames 242; a guide column 26 is arranged on the base 1 along the vertical direction, and the distance adjusting frame 25 slides on the guide column 26 along the vertical direction. A vertical locking unit 27 is arranged between the distance adjusting frame 25 and the guide column 26. The vertical locking unit 27 is used to lock the distance adjusting frame 25 at a low position and a high position. At the low position, the positioning component 2 is adjacent to the top of the base 1. At the high position, the distance between the top of the positioning component 2 and the base 1 and the distance between the positioning component 2 and the base 1 are respectively less than half of the width dimension of the photovoltaic component 4 and greater than half of the width dimension of the photovoltaic component 4; the guide column 26 slides on the base 1 along the first direction and a transverse locking unit 28 is arranged between the two. The transverse locking unit 28 is used to lock the guide column 26 at at least two positions.

[0044] Specifically, Fig.10 and Fig.11As shown, two guide pillars 26 extending in the vertical direction are disposed at both ends above the base 1 , the two guide pillars 26 are distributed along the second direction, and the positioning assembly 2 is disposed between the two guide pillars 26 .

[0045] like Fig.14 and Fig.15 As shown, the lateral locking unit 28 includes a slide rail 281, a slide groove 283 and a locking pin 285, wherein the slide rail 281 and the slide groove 283 both extend along the first direction and slide in cooperation with each other, the slide rail 281 is fixed on the top of the base 1, the slide groove 283 is fixed on the bottom end of the guide column 26, and the slide groove 283 is integrally connected with a locking tube 284 extending along the vertical direction, and a plurality of locking holes 282 distributed along the first direction are provided on the slide rail 281, and the locking tube 284 slides in cooperation with one of the locking holes 282 through the locking pin 285.

[0046] After adopting the above structure, after the locking pin 285 is detached from the slide rail 281, the slide groove 283 can slide along the slide rail 281, and after adjusting the position of the guide column 26 in the length direction of the base 1, the locking pin 285 is inserted so that the locking pin 285 passes through the locking tube 284 and is plugged into one of the locking holes 282. In this way, it is convenient to adjust the distance between the two positioning components 2, so that the packaging structure is suitable for photovoltaic components 4 of different lengths.

[0047] like Figure 16-18 As shown, the vertical locking unit 27 includes a threaded bolt 271 and a nut 272, the guide column 26 is provided with sockets 261 distributed at equal intervals along the vertical direction, the distance adjustment frame 25 includes two slide bars 251 distributed along the vertical direction and extending along the horizontal direction, a horizontal cross plate 252 is provided between the two slide bars 251, the telescopic unit 22 is provided on the cross plate 252, and vertical pipes 253 extending along the vertical direction are provided at both ends of the slide bar 251. The vertical pipe 253 is fixedly connected to the end of the cross plate 252, and a through hole is provided on the vertical pipe 253, and the axial direction of the through hole is parallel to the first direction.

[0048] After adopting the above structure, the height position of the distance adjusting frame 25 is conveniently adjusted through the sliding cooperation of the vertical tube 253 and the guide column 26, and then the height position of the positioning component 2 is adjusted. During the specific operation, the through hole of the vertical tube 253 is aligned with one of the insertion holes 261 on the guide column 26, and then the bolt 271 is passed through the inner side of the through hole and the insertion hole 261, and the nut 272 is tightened to lock the height position of the distance adjusting frame 25, thereby adjusting and locking the height position of the positioning component 2.

[0049] When placing the photovoltaic component 4 on the base 1 or taking the photovoltaic component 4 out of the base 1, the distance adjusting frame 25 is adjusted to the low position so that the positioning component 2 is close to the top of the base 1, which is convenient for inserting the photovoltaic component 4 between the positioning protrusion 201 and the positioning groove 202, or taking out the photovoltaic component 4 from between the positioning protrusion 201 and the positioning groove 202; and when packaging is required, the distance adjusting frame 25 is adjusted and locked at the high position so that the positioning protrusion 201 and the positioning groove 202 in the positioning component 2 can position the middle part of the photovoltaic component 4 in the width direction to ensure the positioning effect.

[0050] The telescopic unit 22 includes an adjusting screw 221, a screw sleeve 222 and a bearing 223. A mounting through hole is provided on the horizontal plate 252. The outer ring of the bearing 223 is fixedly connected to the inner wall of the mounting through hole, and the inner ring is fixedly connected to the circumferential outer edge of the adjusting screw 221, so that the adjusting screw 221 can rotate around its own axis. The screw sleeve 222 is threadedly connected to the adjusting screw 221 and fixedly connected to the extrusion strip 23. The extrusion strip 23 extends along the second direction, and the two ends are integrally connected with a guide rod 231 extending along the vertical direction and sliding through the horizontal plate 252. The end of the guide rod 231 is fixedly connected to a convex plate 232.

[0051] After adopting the above structure, the adjusting screw 221 is rotated, and the screw sleeve 222 drives the extrusion strip 23 to move along the first direction through the slidingly matched guide rod 231 and the cross plate 252, and the extrusion acts on the positioning piece 21, pushing the positioning pieces 21 in the two positioning components 2 to retract. At the same time, the mutually hinged connecting rods 24 are used to reduce the spacing between the positioning pieces 21 until the width of the positioning groove 202 and the width of the positioning protrusion 201 are consistent with twice the height of the frame profile 42 of the photovoltaic component 4, ensuring that each photovoltaic component 4 is closely arranged; when it is necessary to increase the width of the positioning protrusion 201 and the positioning groove 202, the positioning piece 21 is pushed toward the distance adjustment frame 25.

[0052] The positioning piece 21 is close to one side of the telescopic unit 22, and two connecting rods 24 are hinged in the vertical direction. The connecting rods 24 are hinged through the connecting seat 241. The bottom surface of the upper connecting seat 241 is fixedly connected to a sliding frame 242, and the top surface of the lower connecting seat 241 is fixedly connected to the sliding frame 242. The sliding frames 242 at the high and low positions are respectively connected to the two sliding bars 251. Among the sliding frames 242 in each group located at the high position and the low position, one is fixedly connected to the sliding bar 251, and the rest are slidably matched with the sliding bar 251 along the second direction. Preferably, the sliding frame 242 located in the middle position is fixedly connected to the sliding bar 251, so that when the width of the positioning protrusion 201 and the positioning groove 202 increases, the sliding frame 242 and the positioning piece 21 expand to both sides. Correspondingly, when the width of the positioning protrusion 201 and the positioning groove 202 decreases, the sliding frame 242 and the positioning piece 21 move closer to the middle.

[0053] In order to prevent the positioning piece 21 from rigidly contacting the photovoltaic assembly 4 , a buffer pad 211 is provided on the side of the positioning piece 21 away from the spacing frame 25 . The buffer pad 211 is preferably an elastic pad, such as a rubber pad or a silicone pad.

[0054] Two adjacent positioning pieces 21 are used as follows Fig. 20 and Fig.21 The two sides of the positioning piece 21 are fixed with an inner tube 212 and an outer tube 213 which are coaxial, matched and extend in the second direction. On the opposite surfaces of two adjacent positioning pieces 21, the circumferential outer edge of the inner tube 212 is sealed and fitted with the circumferential inner wall of the outer tube 213 to ensure stable sliding fit of the two adjacent positioning pieces 21 in the second direction.

[0055] A limiting unit 29 is arranged between the embedded tube 212 and the outer tube 213 to prevent the inner tube 212 and the outer tube 213 from detaching from each other. Specifically, a strip opening 214 extending along the second direction is arranged on the inner tube 212 and the outer tube 213. The limiting unit 29 includes a limiting screw 291 passing through the inner side of the strip opening 214 and a limiting nut 292 threadedly connected to the limiting screw 291.

[0056] After adopting the above structure, the relative sliding distance between the inner tube 212 and the outer tube 213 can be limited by the limiting screw 291 and the limiting nut 292, thereby preventing the inner tube 212 from being separated from the outer tube 213.

[0057] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
