[0025] The photovoltaic module transport vehicle provided by the technical solution of this application supports the photovoltaic modules through several layers of spaced-apart support assemblies, so that there is a certain gap between the two adjacent photovoltaic modules, reducing the problem of mutual friction or collision between the two adjacent photovoltaic modules, thereby reducing damage to the photovoltaic modules during transportation. In addition, the photovoltaic modules are large photovoltaic components that have been assembled in the workshop. After transportation to the site, it is only necessary to install and fix the photovoltaic modules on the photovoltaic bracket, thereby reducing the amount of outdoor work on site and improving on-site installation efficiency.

[0026] Furthermore, each support assembly layer includes a plurality of spaced support arms, with their support surfaces coplanar. The support arms are pivotally connected to the tooling frame and support the photovoltaic modules horizontally. By pivoting the support arms to the tooling frame, the support arms can be rotated to avoid the photovoltaic modules during loading or unloading, facilitating automated PV module retrieval.

[0027] Furthermore, the support arm is configured to support the support beam. Since the support arm supports the support beam, it has no contact with the photovoltaic panel, thereby reducing damage to the photovoltaic panel during transportation.

[0028] Furthermore, the support arm has a support opening adapted to the support portion of the support beam, and the support opening is configured to abut and support the support beam.

[0029] Furthermore, the support arm is configured as a telescopic or foldable structure, and is configured to rotate from a retracted or folded state to a horizontal state, and to support the photovoltaic module in an extended or unfolded state in the horizontal state. By configuring the support arm as a telescopic or foldable structure, the rotation radius of the support arm can be shortened during rotation, thereby reducing the spacing between adjacent support assemblies, allowing the tooling frame to carry as many photovoltaic modules as possible. When the support arm supports the photovoltaic module, the length of the support arm can be increased to ensure more stable support for the photovoltaic module.

[0030] Furthermore, when the support arm is rotated to a vertical position, the first support portion has a clearance space for accommodating the second support portion of the adjacent support arm, which can further reduce the distance between the upper and lower adjacent support assemblies, allowing the tooling frame to carry as many photovoltaic modules as possible.

[0031] Furthermore, the support arm further includes a stop assembly configured to prevent the second support portion from sliding and retracting when the second support portion slides out of the storage cavity to a first predetermined position. The stop assembly prevents the second support portion from retracting while the support arm is supporting the photovoltaic module, thereby ensuring stable support for the photovoltaic module.

[0032] Furthermore, the backstop assembly further includes: a backstop base fixedly connected to the first support portion, a backstop member rotatably connected to the backstop base; a second backstop opening formed on the first support portion, the backstop member extending through the second backstop opening and abutting the second support portion when the second support portion is in a retracted state; and an elastic member including a first end and a second end opposite each other, the first end fixedly connected to the backstop base or the first support portion, the second end fixedly connected to the backstop member, and configured to elastically act on the backstop member so that the backstop member rotates into the first backstop opening when the second support portion extends to a first preset position. The elastic member enables automatic coordination between the backstop member and the first backstop opening.

[0033] Furthermore, the support arm is configured so that its center of gravity is vertically located above or below the pivot point between the support arm and the tooling frame, allowing the support arm to rotate to a horizontal or vertical position under the action of gravity. By configuring the support arm to rotate to a horizontal or vertical position in conjunction with gravity, the support arm avoids the need for photovoltaic modules during loading or unloading, facilitating automated PV module retrieval. Furthermore, the structure is simple, practical, and cost-effective.

[0034] Furthermore, the system includes at least one guide member fixedly connected to the tooling frame and configured to guide the picker assembly into the tooling frame when grabbing a photovoltaic module. After the photovoltaic module is transported to the installation site, the picker assembly at the installation site can be quickly guided to the precise grabbing position by the guide member, thereby improving the efficiency of photovoltaic module installation.

[0035] Furthermore, the tooling frame includes at least two frame sections, and at least two of the frame sections are detachably connected. Because the overall tooling frame is relatively large, exceeding the size of conventional items permitted for highway transport, the tooling frame is configured as at least two detachably connected frame sections, each of which is within the size of conventional items permitted for highway transport. After each frame section is transported to the photovoltaic module production plant, it is assembled to form the tooling frame, thereby enabling the deployment of the tooling frame.

[0046] As described in the background art, photovoltaic panels are currently prone to damage from bumps or friction during transportation, and after the photovoltaic panels are transported to the installation site, the workload on site is heavy.

[0047] On this basis, the present invention provides a photovoltaic module transport carrier that supports the photovoltaic modules through several layers of spaced-apart support assemblies, so that a certain gap exists between two adjacent photovoltaic modules, reducing the problem of mutual friction or collision between the two adjacent photovoltaic modules, thereby reducing damage to the photovoltaic modules during transportation. In addition, the photovoltaic modules are large photovoltaic components that have been assembled in the workshop. After transportation to the site, it is only necessary to install and fix the photovoltaic modules on the photovoltaic bracket, thereby reducing the amount of outdoor work on site and improving on-site installation efficiency.

[0051] Referring to Figures 1 to 3, a photovoltaic module transport vehicle comprises: a tooling frame 10; and a plurality of layers of support assemblies 20 spaced apart in a vertical direction, each layer of support assemblies 20 being connected to the tooling frame 10 and configured to support a photovoltaic module 30. The photovoltaic module 30 comprises at least one support beam 301 and a plurality of photovoltaic panels 302 supported and fixed by at least one support beam 301. Although four support beams 301 are illustrated in Figure 2, the number and specific shape of the support beams 301 are not specifically limited herein. Furthermore, the extension direction of the support beams 301 is also not limited. For example, but not limited to, the support beams 301 may extend parallel to the long sides of the photovoltaic panel array in Figure 2 and / or extend parallel to the short sides of the photovoltaic panel array in Figure 2.

[0052] The photovoltaic modules are supported by several layers of spaced-apart support assemblies 20, ensuring a certain gap between two adjacent photovoltaic modules 30. This reduces friction or collisions between the two adjacent photovoltaic modules 30, thereby reducing damage to the photovoltaic modules 30 during transportation. Furthermore, the photovoltaic modules 30 are large, pre-assembled photovoltaic components, and assembly work has already been completed in the workshop. After transport to the site, only the photovoltaic modules 30 need to be installed and secured on the photovoltaic supports, reducing on-site outdoor work and improving on-site installation efficiency.

[0053] It is understood that the tooling frame 10 is the main structure supporting the photovoltaic modules 30, and it is required to be surrounded by a plurality of frame components to form a cavity with a certain load-bearing space. In some embodiments, the plurality of frame components can be in the form of welded longitudinal beams and transverse beams. In some embodiments, the plurality of frame components can also be in the form of cross-welded diagonal beams, with the intersecting diagonal beams forming a diamond grid.

[0054] Continuing with reference to FIG1 , in some embodiments, each layer of the support assembly 20 includes a plurality of spaced support arms 201, with the support surfaces of the plurality of support arms 201 being coplanar. The support arms 201 are rotatably connected to the tooling frame 10, and the support arms 201 horizontally support the photovoltaic modules 30. By rotatably connecting the support arms 201 to the tooling frame 10, the support arms 201 can be rotated to avoid the photovoltaic modules 30 during loading or unloading, facilitating automated retrieval of the photovoltaic modules 30.

[0055] Continuing with Figures 2 and 3, in some embodiments, the support arm 201 is configured to support the support beam 301. Since the photovoltaic panel 302 is relatively fragile, if the support arm 201 directly abuts and supports the photovoltaic panel 302, it is likely to damage the photovoltaic panel 302, thereby preventing the photovoltaic panel 302 from properly performing photoelectric conversion. Therefore, the support arm 201 directly abuts and supports the support beam 301 without contacting the photovoltaic panel 302, thereby reducing damage to the photovoltaic panel 302 during transportation.

[0056] Referring to Figures 4 and 5, in some embodiments, the support arm 201 has a support opening 2013 that matches the supporting portion of the support beam 301. The support opening 2013 is configured to provide abutment support to the support beam 301. In other words, the support opening 2013 and the supporting portion of the support beam 301 have substantially the same cross-sectional shape to better wrap and accommodate the supporting portion of the support beam 301. By limiting the support beam 301 through the support opening 2013, the support stability of the photovoltaic module 30 can be effectively improved during transportation.

[0057] In some embodiments, a protrusion may be provided on the support arm, and a recess may be provided at a position corresponding to the support beam, so that the support beam can be limited by the cooperation between the protrusion and the recess.

[0058] Continuing to refer to FIG4 and FIG5 , in some embodiments, the support arm 201 is configured as a telescopic structure, and the support arm 201 is configured to be able to rotate from a retracted state to the horizontal state, and to support the photovoltaic module 30 in an extended state in the horizontal state. By configuring the support arm 201 as a telescopic structure, the rotation radius of the support arm 201 can be shortened during the process of rotating the support arm 201 to the horizontal state, thereby reducing the distance between the upper and lower adjacent support assemblies 20, so that the tooling frame 10 can carry as many photovoltaic modules 30 as possible; supporting the photovoltaic module 30 in an extended state in the horizontal state ensures more stable support for the photovoltaic module 30. Furthermore, when the support arm 201 supports the support beam 301 of the photovoltaic module 30, since there is a certain distance between the support beam 301 and the edge of the photovoltaic panel 302, the retractable structure of the support arm 201 can increase the length of the support arm 201 to support the support beam 301 of the photovoltaic module 30, thereby avoiding damage to the photovoltaic panel 302, and at the same time shortening the rotation radius of the support arm 201, thereby improving the load-bearing capacity of the tooling frame 10.

[0059] Continuing to refer to Figures 4 and 5, in some embodiments, the support arm 201 is a telescopic structure and includes: a first support portion 2011, which is rotatably connected to the tooling frame 10 and has a storage cavity (not shown); and a second support portion 2012, which is slidably connected to the first support portion 2011 and is configured to slidably retract into the storage cavity, or slidably extend from the storage cavity, to increase or decrease the length of the support arm 201. In some embodiments, the first support portion 2011 is provided with an adapter hole 2018, which cooperates with a rotating shaft (not shown) passing through the adapter hole 2018 to enable the first support portion 2011 to be rotatably connected to the tooling frame 10.

[0060] Continuing with reference to Figures 4 and 5 , in some embodiments, the second support portion 2012 has a support opening 2013 that matches the support portion of the support beam 301. The support opening 2013 is configured to support the support beam 301. Figure 2 shows that the cross-sectional shape of the support beam 301 is rectangular, so the cross-sectional shape of the support opening 2013 shown in Figures 4 and 5 is a corresponding "U" shape. Although the cross-sectional shape of the support opening 2013 shown in Figures 4 and 5 is "U"-shaped, the cross-sectional shape of the support opening 2013 should be consistent with the cross-sectional shape of the support beam 301, and the cross-sectional shape of the support opening 2013 is not specifically limited herein.

[0061] Please continue to refer to Figure 4. In some embodiments, the support arm 201 also includes: a first limit member 2014, which is fixedly connected to the first support part 2011 or the second support part 2012, and is configured to prevent the second support part 2012 from continuing to slide out when the second support part 2012 slides out from the storage cavity to the first preset position.

[0062] In some embodiments, the first preset position can be a position where the second support portion 2012 can stably support the photovoltaic module 30 after sliding out, for example, the support beam 301 can be supported by the second support portion 2012. At this position, the tail of the second support portion 2012 (i.e., the portion connected to the first limiting member 2014) and the first support portion 2011 have an overlapping area of ​​a certain length. This partial overlapping area ensures that when the second support portion 2012 supports the support beam, it can provide force abutment and limitation for the second support portion 2012.

[0063] Continuing with FIG4 , in some embodiments, the first stopper 2014 can be a protrusion fixedly connected to the second support portion 2012 and a notch defined in the first support portion 2011, with the protrusion fitting in and corresponding to the notch. When the second support portion 2012 slides out of the receiving cavity to the first predetermined position, the movement of the protrusion is limited by the notch, at which point the protrusion is blocked, preventing the second support portion 2012 from sliding out further.

[0064] In some embodiments, the first stopper may be a sliding block fixedly connected to the second support portion and a sliding groove provided in the first support portion (or a sliding groove provided in the second support portion and a sliding block fixedly connected to the first support portion), wherein the sliding block is confined within the sliding groove and can slide back and forth along the sliding groove. When the second support portion slides out of the receiving cavity to the first preset position, the sliding block just slides to the end of the sliding groove, at which point the sliding block will be blocked, preventing the second support portion from sliding out further.

[0065] Please continue to refer to Figure 5. In some embodiments, the support arm 201 also includes: a second limit member 2015, which is fixedly connected to the first support part 2011 or the second support part 2012, and is configured to prevent the second support part 2012 from continuing to slide and shrink when the second support part 2012 slides and shrinks in the storage cavity to a second preset position.

[0066] In some embodiments, the second preset position can correspond to the rotation radius of the support arm 201, for example but not limited to, after the second support part 2012 slides and retracts, the head of the second support part 2012 (the part opposite to the tail of the second support part 2012) is just completely retracted to the position inside the first support part 2011.

[0067] Please continue to refer to Figure 5. In some embodiments, the second limiting member 2015 adopts a stop block fixedly connected to the end position of the second support part 2012. When the second support part 2012 slides and shrinks in the storage cavity to the second preset position, the stop block will be blocked by the first support part 2011, so that the second support part 2012 cannot continue to slide and shrink.

[0068] In some embodiments, the second limiting member may also be a stopper fixedly connected to the end position of the first supporting portion.

[0069] Continuing with reference to Figures 6 and 7, in some embodiments, the support arm 201 further comprises a stopper assembly 2016 configured to prevent the second support portion 2012 from sliding and retracting when the second support portion 2012 slides out of the receiving cavity to a first predetermined position. The stopper assembly 2016 prevents the second support portion 2012 from retracting while the support arm 201 is supporting the photovoltaic module 30, thereby ensuring stable support for the photovoltaic module 30.

[0070] Please continue to refer to Figures 6 and 7. In some embodiments, the backstop assembly 2016 includes: a first backstop opening 2016a, which is opened on the second support portion 2012; and a backstop member 2016b, which is configured to enter the first backstop opening 2016a when the second support portion 2012 slides out from the storage cavity to the first preset position.

[0071] Please continue to refer to Figures 6 and 7 in combination with Figure 8. In some embodiments, the backstop assembly 2016 further includes: a backstop base 2016c, fixedly connected to the first support portion 2011, and the backstop member 2016b is rotatably connected to the backstop base 2016c; a second backstop opening 2016d, which is opened on the first support portion 2011, and the backstop member 2016b extends through the second backstop opening 2016d and abuts the second support portion 2012 when the second support portion 2012 is in a retracted state; an elastic member 2016e, including a first end and a second end opposite to each other, the first end being fixedly connected to the backstop base 2016c or the first support portion 2011, and the second end being fixedly connected to the backstop member 2016b, and being configured to elastically act on the backstop member 2016b, so that the backstop member 2016b rotates into the first backstop opening 2016a when the second support portion 2012 extends to the first preset position. The elastic member 2016e can realize automatic matching between the retaining member 2016b and the first retaining opening 2016a.

[0072] It should be noted that, when the retaining member 2016b rotates into the first retaining opening 2016a, the first retaining opening 2016a and the second retaining opening 2016d overlap.

[0073] In some embodiments, the first support part can be slidably mounted on the second support part to realize a retractable structure composed of the first support part and the second support part. Correspondingly, the backstop assembly can also adopt an elastic protrusion provided on the first support part. Along the direction in which the second support part slides out, the elastic protrusion has a chamfered angle, and along the direction in which the second support part slides and retracts, the elastic protrusion has a blocking plane. The backstop assembly can be compared to the backstop structure of common umbrellas currently on the market, so as to achieve the effect of blocking the second support part. When the second support part is not performing a supporting action and needs to be retracted, the elastic protrusion can be manually pressed to release the blocking of the elastic protrusion on the second support part, thereby ensuring that the second support part can slide and retract smoothly.

[0074] In some embodiments, the support arm is configured as a foldable structure, and the support arm is configured to be able to rotate from the folded state to the horizontal state, and support the photovoltaic module in the unfolded state in the horizontal state. By configuring the support arm as a foldable structure, the rotation radius of the support arm can be shortened during the rotation of the support arm, thereby reducing the distance between the upper and lower adjacent support assemblies, so that the tooling frame can carry as many photovoltaic modules as possible; when the support arm supports the photovoltaic module, the length of the support arm can be increased to ensure more stable support for the photovoltaic module.

[0075] In some embodiments, the support arm is a foldable structure comprising a first support portion and a second support portion, the first support portion having a cavity for receiving the second support portion. When the second support portion is no longer needed, the second support portion rotates and folds into the cavity; when the second support portion is needed, the second support portion rotates and unfolds from the cavity. This structure is similar to that of common foldable knives currently on the market.

[0076] Please continue to refer to Figure 1 and Figures 4 to 7. In some embodiments, the support arm 201 is further configured to be based on the rotation point of the support arm 201 and the tooling frame 10, and the center of gravity of the support arm 201 is located above or below the rotation point in the vertical direction, so that the support arm 201 can rotate to a horizontal state or a vertical state under the action of gravity. Correspondingly, the support arm 201 also needs to be configured with: a third limiter 2017, which is configured to prevent the support arm 201 from continuing to rotate in the same direction when the support arm 201 rotates to support the photovoltaic module 30 in the horizontal state. The support arm 201 is configured to rotate to a horizontal state or a vertical state in combination with gravity to avoid the photovoltaic module 30 during the loading or unloading process, which is conducive to the automated operation of unloading the photovoltaic module 30. In addition, the structure is simple and practical, and the cost is low.

[0077] Referring to FIG. 9 , in some embodiments, the initial state of the support arms 201 is vertical, meaning the center of gravity of the support arms 201 is located below the rotation point in the vertical direction. During the installation of the photovoltaic modules 30, each support arm 201 can rotate to a vertical state under the action of gravity. Therefore, regardless of whether the installation is performed from the top or bottom opening of the tooling frame 10, the support arms 201 at each layer will not obstruct the photovoltaic modules 30. When the photovoltaic modules 30 are moved to the position of the support arms 201 at a certain layer, the support arms 201 at that layer are manually rotated to a horizontal state to support the photovoltaic modules 30. This cycle is repeated until all support arms 201 at each layer are supporting the photovoltaic modules 30. It should be noted that regardless of whether the photovoltaic modules 30 are installed from the top or bottom opening of the tooling frame 10, the installation must be performed sequentially. If the photovoltaic module 30 is installed from the upper opening of the tooling frame 10, the photovoltaic module 30 needs to be supported on the lowest support arm 201 first; if the photovoltaic module 30 is installed from the lower opening of the tooling frame 10, the photovoltaic module 30 needs to be supported on the topmost support arm 201 first.

[0078] Continuing with FIG9 , in some embodiments, when the support arm 201 is rotated to a vertical position, the first support portion 2011 has a clearance space to accommodate at least a portion of the vertically adjacent support arm 201 (such as, but not limited to, the second support portion 2012). This can further reduce the spacing between upper and lower adjacent support assemblies 20, allowing the tooling frame 10 to carry as many photovoltaic modules 30 as possible.

[0079] In some embodiments, the initial state of the support arm is horizontal, that is, the center of gravity of the support arm is located below the rotation point in the vertical direction. During the installation of the photovoltaic module, since each support arm can rotate to a horizontal state under the action of gravity, installation can only be carried out from the bottom opening of the tooling frame. The support arms of each layer will block the photovoltaic module. However, when the photovoltaic module is lifted for installation, the support arms of each layer can be temporarily pushed aside to avoid the impact. After the photovoltaic module is lifted and passes a certain layer of support arms, the support arms will rotate back to a horizontal state under the action of gravity. During this process, to minimize damage to the photovoltaic module caused by lifting each layer of support arms, each support arm is chamfered along the direction of the photovoltaic module installation. It should be noted that the photovoltaic modules need to be installed sequentially from the bottom opening of the tooling frame. That is, the photovoltaic module installed first needs to be supported on the support arms of the top layer.

[0080] Continuing with reference to Figures 1 and 3, in some embodiments, the photovoltaic module 30 transport vehicle further includes: at least one guide member 40 fixedly connected to the tooling frame 10, configured to guide the retrieving assembly into the interior of the tooling frame 10 when the retrieving assembly grasps the photovoltaic module 30. After the photovoltaic module 30 is transported to the installation site, the retrieving assembly at the installation site can be quickly guided to the accurate grasping position by the guide member 40, thereby improving the installation efficiency of the photovoltaic module 30.

[0081] It should be noted that if the material-picking component picks up items from the upper opening of the tooling frame 10, the guiding direction of the guide member 40 is from the photovoltaic module 20 stacked at the top toward the photovoltaic module 20 stacked at the bottom; if the material-picking component picks up items from the lower opening of the tooling frame 10, the guiding direction of the guide member 40 is from the photovoltaic module 20 stacked at the bottom toward the photovoltaic module 20 stacked at the top.

[0082] Please continue to refer to FIG. 1 and FIG. 3 . In a specific embodiment, the number of the guide members 40 can be set to four, which are respectively assembled at the four corner positions of the tooling frame 10 .

[0083] Continuing with reference to FIG1 , in some embodiments, the guide member 40 includes two parallel guide rails 401 disposed at the top corners of the tooling frame 10, with the rail surfaces of the two guide rails 401 being perpendicular to each other, and a portion of the retrieving assembly can travel on the rail surfaces; wherein each guide rail 401 includes a top guide head 4011, the guide head 4011 being higher than the tooling frame 10 and extending toward the outside of the tooling frame 10. The function of the guide head 4011 is to increase the guide angle, so that the retrieving assembly can be quickly guided to the accurate grasping position.

[0084] In some embodiments, the guide member may further include: a guide groove, in which a portion of the material picking assembly can move; wherein, the guide groove includes a guide head at the top, the guide head is higher than the tooling frame, and the guide head extends toward the outside of the tooling frame.

[0085] Referring to FIG. 10 , in some embodiments, the tooling frame 10 includes at least two frame portions 101, and at least two of the frame portions 101 are detachably connected. Because the overall tooling frame 10 is relatively large, exceeding the size of conventional items permitted for transportation by road, the tooling frame 10 is configured as at least two detachably connected frame portions 101, each of which is within the size of conventional items permitted for transportation by road. After each frame portion 101 is transported to the production plant of the photovoltaic modules 30, they are assembled to form the tooling frame 10, thereby enabling the deployment of the tooling frame 10.

[0086] Although the present application is disclosed as above, the present application is not limited thereto. Any person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present application. Therefore, the scope of protection of the present application shall be based on the scope defined by the claims.
