[0002] As traditional fossil energy causes greenhouse effect and other issues, the call for low-carbon and environmental protection is becoming stronger. In this context, the pursuit of clean energy is gradually increasing. Compared with traditional fossil energy, solar energy, as a high-quality clean energy, is favored by people because it is easy to obtain and does not produce pollutants.

[0028] Example

[0029] This embodiment provides a packaging device 100. Please also refer to Figure 1 and Figure 2 The packaging device 100 is used to package a photovoltaic panel 200 . The photovoltaic panel 200 is a wave-shaped structure. The photovoltaic panel 200 is fixed in the packaging device 100 .

[0030] Specifically, the wavy structure allows the photovoltaic panel 200 to adapt to the installation environment, such as a tile roof. The tiles on the roof are also wavy in structure, and the photovoltaic panel 200 of the same structure can overlap with the tiles to facilitate the connection between the two. In addition, the tiles and the photovoltaic panel 200 have the same structure. In terms of integrity, the photovoltaic panel 200 can be better integrated into the installation environment, which can make the photovoltaic panel 200 more beautiful. At the same time, compared with the flat photovoltaic panel 200, the wavy structure can improve the strength and stability of the photovoltaic panel 200 itself.

[0031] Further, such as Figure 2 As shown, the photovoltaic panel 200 has a plurality of crests 210 and a plurality of troughs 220, and the plurality of crests 210 and the plurality of troughs 220 are arranged alternately, and the curvature radii of the crests 210 and the troughs 220 can be set to be the same or different, and this embodiment does not limit this. The edge of the photovoltaic panel 200 can be configured as the peak of the crest 210 or the bottom of the trough 220 or any point between the peak and the bottom, and can be set according to the specific implementation scenario and size of the photovoltaic panel 200, and this embodiment does not limit this.

[0032] In one embodiment, please refer to Figure 2 The edge of the photovoltaic panel 200 is provided with a connector 230, which can be used in the subsequent installation of the photovoltaic panel 200. In the implementation environment, the connector 230 connects multiple photovoltaic panels 200 to ensure that a larger light-receiving surface is obtained. Alternatively, the photovoltaic panel 200 is installed in the implementation scenario through the connector 230 to improve the installation effect of the photovoltaic panel.

[0033] For more details, see Figure 3 The packaging device 100 may include an outer frame 110 and a plurality of fixing members 120 , wherein the plurality of fixing members 120 fix the photovoltaic panel 200 , and the plurality of fixing members 120 and the photovoltaic panel 200 are disposed together in the accommodating cavity 111 .

[0034] Please review Figure 1 The outer frame 110 can be set to a cubic structure or a prism structure. The outer frame 110 with a regular shape is convenient for handling and stacking, which is conducive to improving the efficiency of transportation and packaging. At the same time, compared with an irregular shape, the outer frame 110 with a regular shape is more uniform in force, and the outer frame 110 has a greater bearing capacity, which avoids damage to the outer frame 110 caused by stacking multiple packaging devices 100.

[0035] The outer frame 110 can be configured as a wooden frame, which is low in cost and hardness and has a certain buffering effect. The outer frame 110 can reduce costs while protecting the photovoltaic panel 200 in the accommodating cavity 111. In some other cases, such as high static electricity, high humidity environment, etc., the outer frame 110 can also be configured as a metal frame or a plastic frame, etc., which is not limited in this embodiment.

[0036] See also Figure 3 The outer frame 110 may have a receiving cavity 111. Further, the outer frame 110 may include a bottom plate 112 and a top plate 113 opposite to each other, and a side plate 114 connected between the bottom plate 112 and the top plate 113. The bottom plate 112, the top plate 113, and the side plate 114 may enclose the receiving cavity 111. The outer frame 110 may provide a certain support force for the fixing member 120 and the photovoltaic panel 200 in the receiving cavity 111, thereby preventing the fixing member 120 and the photovoltaic panel 200 from being squeezed by external force, and providing a certain protection effect.

[0037] In one embodiment, see Figure 4 , the top plate 113 is detachably connected to the side plate 114, and the connection method between the top plate 113 and the side plate 114 includes but is not limited to connection with fasteners such as screws and bolts, and can also be connected by straps, and the straps are nylon straps, plastic straps, etc., which are not limited in this embodiment. The side plate 114 is interconnected with the bottom plate 112, and the top plate 113 selectively closes or opens the accommodating cavity 111. When it is necessary to place the photovoltaic panel 200 in the accommodating cavity 111, the top plate 113 is removed to open the accommodating cavity 111 to facilitate the placement of the photovoltaic panel 200. When packaging processing is required, the top plate 113 and the side plate 114 are interconnected to close the accommodating cavity 111, improve the sealing of the accommodating cavity 111, and prevent foreign matter from entering the accommodating cavity 111.

[0038] It is understandable that the size of the photovoltaic panel 200 can be configured larger to adapt to its usage scenario. In the process of packaging photovoltaic panels 200 of larger sizes, the transport personnel need to use tools such as ladders to complete the connection between the top plate 113 and the side plate 114, which affects the packaging efficiency. In addition, the photovoltaic panel 200 should not be laid flat. The photovoltaic panels 200 laid flat are prone to mutual squeezing and the like under the influence of gravity. In another embodiment, the bottom plate 112 is detachably connected to the side plate 114, and the side plate 114 and the top plate 113 are interconnected as a whole, and the bottom plate 112 selectively closes or opens the accommodating cavity 111. During the packaging process, the transport personnel separate the bottom plate 112 and the side plate 114 to open the accommodating cavity 111. The transport personnel can place the photovoltaic panel 200 on the bottom plate 112, and then cover the side plate 114 and the top plate 113 on the photovoltaic panel 200 and the bottom plate 112, and then connect the bottom plate 112 and the side plate 114 to complete the packaging of the photovoltaic panel 200. Compared with the top plate 113, the relative position of the bottom plate 112 is lower, and it is more convenient to complete the connection between the bottom plate 112 and the side plate 114. This setting is suitable for the packaging of large-sized photovoltaic panels 200, and effectively ensures the installation effect of large-sized photovoltaic panels 200.

[0039] In one embodiment, continue Figure 4 The outer frame 110 may also be provided with ribs 115, and the ribs 115 are arranged on the outside of the bottom plate 112 and the side plate 114. The ribs 115 can improve the strength and rigidity of the outer frame 110, avoid deformation of the outer frame 110, and effectively ensure the transportation safety of the photovoltaic panel 200 arranged in the outer frame 110.

[0040] In this embodiment, please refer to Figure 3 and Figure 5 Each fixing member 120 has an arc groove 121 suitable for inserting the photovoltaic panel 200. The extension direction of the arc groove 121 can be circular arc, elliptical arc, wave, etc., and the arc groove 121 can be a circular arc groove, an elliptical arc groove, a wave groove, etc. The shape and size of the arc groove 121 can be adapted to the photovoltaic panel 200. More specifically, the radius of curvature of the arc groove 121 is the same as the radius of curvature of the crest part 210 or the trough part 220 of the photovoltaic panel 200, and the shape of the arc groove 121 is the same as or similar to the shape of the crest part 210 and the trough part 220. This setting can enable the photovoltaic panel 200 to be smoothly fixed in the arc groove 121.

[0041] Exemplarily, the arc groove 121 may extend in a wavy direction, that is, the arc groove 121 may also be a wavy groove, and the wavy groove is adapted to the wavy photovoltaic panel 200. Furthermore, one end of the photovoltaic panel 200 may be directly inserted into the arc groove 121 to fix the photovoltaic panel 200 in the outer frame 110.

[0042] In one implementation scenario, as mentioned above, Figure 2 As shown, a connector 230 is provided at the edge of the photovoltaic panel 200, and the arc groove 121 can be configured with an installation space (not shown in the figure), and the shape and size of the installation space are the same as or similar to the connector 230. This setting can constrain the connector 230 within the installation space, thereby further constraining the freedom of the photovoltaic panel 200, so as to improve the transportation safety of the photovoltaic panel 200.

[0043] Please refer to Figure 3 The fixing part 120 is arranged between the photovoltaic panel 200 and the outer frame 110. The fixing part 120 may have sufficient buffering performance and flexibility. The fixing part 120 may absorb the force transmitted from the outer frame 110 to the photovoltaic panel 200 to prevent the photovoltaic panel 200 from being damaged during transportation, packaging, and disassembly. The fixing part 120 may be foam or foam or silicone. The foam has the characteristics of resistance to compression deformation and flame retardancy. The foam has the characteristics of fire and moisture resistance and good energy absorption effect. The silicone has the characteristics of high temperature resistance, corrosion resistance, aging resistance, plasticity and adhesion. The selection and design of the fixing part 120 are carried out according to the specific implementation scenario, and this implementation does not limit it.

[0044] In one embodiment, the width of the arc groove 121 is smaller than the thickness of the photovoltaic panel 200, and the photovoltaic panel 200 and the arc groove 121 can be configured as an interference fit. The interference fit photovoltaic panel 200 and the arc groove 121 can further limit the photovoltaic panel 200, prevent the photovoltaic panel 200 from moving or tilting during transportation, and improve the safety of the photovoltaic panel 200 during transportation. In addition, the fixing member 120 can be configured as foam or foam or silicone with deformation ability, and the interference fit will not cause the fixing member 120 to scratch or squeeze the photovoltaic panel 200. At the same time, the photovoltaic panel 200 can still be easily inserted into the fixing member 120 without affecting the packaging efficiency.

[0045] It is understandable that in other cases, in order to ensure that the photovoltaic panel 200 is smoothly inserted into the arc groove 121, the groove width of the arc groove 121 is greater than or equal to the thickness of the photovoltaic panel 200, and the photovoltaic panel 200 and the arc groove 121 can be configured as a transition fit or a clearance fit. The transition fit or the clearance fit makes it easier for the photovoltaic panel 200 to be inserted into the arc groove 121, thereby further improving the packaging efficiency.

[0046] For more details, see Figure 3 , Figure 6 as well as Figure 7The plurality of fixing members 120 may include a first fixing member 122, a second fixing member 123, a third fixing member 124 and a fourth fixing member 125. The first fixing member 122 and the second fixing member 123 are relatively arranged on the bottom plate 112, the arc groove 121 of the first fixing member 122 is arranged at one end of the first fixing member 122 close to the second fixing member 123, and the arc groove 121 of the second fixing member 123 is arranged at one end of the second fixing member 123 close to the first fixing member 122, and the photovoltaic panel 200 can be inserted into the arc grooves 121 of the first fixing member 122 and the second fixing member 123 at the same time. In addition, the first fixing member 122 and the second fixing member 123 are in contact with the side plate 114 of the outer frame 110, and the first fixing member 122 and the second fixing member 123 can fix the photovoltaic panel 200 in the accommodating cavity 111 to ensure the transportation safety of the photovoltaic panel 200.

[0047] The third fixing member 124 and the fourth fixing member 125 are arranged opposite to each other and adjacent to the top plate 113. The arc groove 121 of the third fixing member 124 is arranged at one end of the third fixing member 124 close to the fourth fixing member 125, and the arc groove 121 of the fourth fixing member 125 is arranged at one end of the fourth fixing member 125 close to the fourth fixing member 125. In addition, the third fixing member 124 and the fourth fixing member 125 abut against the side plate 114 of the outer frame 110. On the premise that the photovoltaic panel 200 is inserted into the first fixing member 122 and the second fixing member 123, the photovoltaic panel 200 can also be inserted into the arc grooves 121 of the third fixing member 124 and the fourth fixing member 125. Furthermore, the first fixing member 122, the second fixing member 123, the third fixing member 124 and the fourth fixing member 125 can respectively fix the four corners of the photovoltaic panel 200, and the four fixing members work together to restrain the photovoltaic panel 200, thereby preventing the photovoltaic panel 200 from shaking, bumping, etc. during transportation, and further improving the transportation safety of the photovoltaic panel 200.

[0048] It is understandable that, compared with other parts, the corners of the photovoltaic panel 200 are subjected to more concentrated forces, and are more susceptible to damage, etc. Therefore, the multiple corners of the photovoltaic panel 200 in this embodiment can be inserted into multiple fixing members 120, that is, the photovoltaic panel 200 is fixed between the multiple fixing members 120 through the corners, and the fixing members 120 can wrap the corners and provide a certain buffering effect to prevent the exposed corners from being damaged by forces.

[0049] In one embodiment, see Figure 6, the structures of the first fixing member 122, the second fixing member 123, the third fixing member 124 and the fourth fixing member 125 can be configured as the same structure. Exemplarily, the first fixing member 122, the second fixing member 123, the third fixing member 124 and the fourth fixing member 125 are all strip structures, which can fit with the inner wall of the outer frame 110, increase the contact area between the fixing member 120 and the inner wall of the outer frame 110, further improve the connection stability between the fixing member 120 and the outer frame 110, and improve the transportation safety of the photovoltaic panel 200.

[0050] The first fixing member 122, the second fixing member 123, the third fixing member 124 and the fourth fixing member 125 of the same structure can be arranged relative to each other, and thus the arc-shaped grooves 121 of the four fixing members can also be arranged relative to each other. Figure 6 , the first fixing member 122 may include a first arc groove 1221, the second fixing member 123 may include a second arc groove 1231, the third fixing member 124 may include a third arc groove 1241, and the fourth fixing member 125 may include a plurality of arc grooves 1251. The first arc groove 1221, the second arc groove 1231, the third arc groove 1241 and the fourth arc groove 1251 are arranged relatively, and the four corners of each photovoltaic panel can be inserted into the first arc groove 1221, the second arc groove 1231, the third arc groove 1241 and the fourth arc groove 1251 arranged relatively, and then the correspondingly arranged plurality of arc grooves 121 can fix the same photovoltaic panel 200. In one embodiment, in order to further improve the transportation efficiency of the photovoltaic panel 200, the first fixing member 122, the second fixing member 123, the third fixing member 124 and the fourth fixing member 125 are all provided with a plurality of arc grooves 121, that is, the number of the first arc groove 1221, the second arc groove 1231, the third arc groove 1241 and the fourth arc groove 1251 is multiple, and the multiple arc grooves 121 are arranged side by side at intervals. Correspondingly, the multiple first arc grooves 1221, the second arc grooves 1231, the third arc grooves 1241 and the fourth arc grooves 1251 arranged corresponding to each other can also fix multiple photovoltaic panels 200 at the same time, thereby increasing the transportation quantity of the photovoltaic panels 200 of the single packaging device 100 and improving the transportation efficiency of the photovoltaic panels 200.

[0051] More specifically, any two of the first fixing member 122, the second fixing member 123, the third fixing member 124, and the fourth fixing member 125 are arranged in parallel. The parallel arrangement is conducive to efficient use of the space occupied by the plurality of fixing members 120, avoiding the space waste that may be caused by the non-parallel arrangement, and improving the overall space utilization.

[0052] Any two fixing members 120 are arranged in parallel and correspondingly, and the multiple arc grooves 121 of the two are arranged correspondingly to fix multiple photovoltaic panels 200 of the same size. Exemplarily, the first fixing member 122 and the second fixing member 123 are arranged in parallel and correspondingly, the first fixing member 122 may include multiple first arc grooves 1221, and the second fixing member 123 may include multiple second arc grooves 1231. The multiple first arc grooves 1221 and the multiple second arc grooves 1231 correspond to each other one by one. The correspondingly arranged first arc grooves 1221 and second arc grooves 1231 can be regarded as a group of arc groove groups, and the spacing between the first arc grooves 1221 and the second arc grooves 1231 of the multiple groups of arc groove groups is the same. This configuration can install multiple photovoltaic panels 200 of the same size, reduce the difficulty of using the packaging device 100, and improve transportation efficiency.

[0053] In some other embodiments, the first fixing member 122 , the second fixing member 123 , the third fixing member 124 and the fourth fixing member 125 may be arranged in parallel to accommodate a plurality of photovoltaic panels 200 of the same size and further improve the fixing effect of the fixing member 120 .

[0054] In some other cases, due to different installation surfaces, the overall shape of the photovoltaic panel 200 is irregular, and the shapes of multiple parts of the photovoltaic panel 200 are also different. Correspondingly, the first fixing member 122, the second fixing member 123, the third fixing member 124, and the fourth fixing member 125 in this embodiment can also be configured as different structures to adapt to multiple parts of different shapes of the photovoltaic panel 200, so as to improve the safety of the photovoltaic panel 200 during transportation.

[0055] Preferably, the spacing between two adjacent arc grooves 121 is 10mm-30mm. The spacing between the arc grooves 121 should not be set too large or too small. When the spacing between the arc grooves 121 is set too large, the number of photovoltaic panels 200 that can be installed in a single packaging device 100 is reduced, thereby reducing the transportation efficiency of the photovoltaic panels 200. When the spacing between the arc grooves 121 is set too small, two adjacent photovoltaic panels 200 may collide during transportation, resulting in reduced transportation safety of the photovoltaic panels 200. Arc grooves 121 with appropriate spacing can ensure the transportation safety of the photovoltaic panels 200 while increasing the number of photovoltaic panels 200 that can be installed in a single packaging device 100, thereby improving the transportation efficiency of the photovoltaic panels 200.

[0056] In one embodiment, please refer to Figure 3, among the multiple arc grooves 121 on each fixing member 120, the spacing between any two adjacent arc grooves 121 can be equal. The equidistant arc grooves 121 can make the fixing member 120 more standardized, easy to manufacture and process, and this setting also helps to enhance the structural stability of the fixing member 120. When multiple arc grooves 121 are evenly distributed, they can jointly bear and disperse the load, reduce single-point force, and improve the strength and stability of the overall structure. At the same time, since the spacing between the arc grooves 121 is equal, the transportation personnel can determine and locate the required arc groove 121 position more quickly, thereby improving the packaging efficiency.

[0057] In this example, please refer to Figure 5 The fixing member 120 may include a first surface 126 and a second surface 127 opposite to each other and a side surface 128 connected between the first surface 126 and the second surface 127. The arc groove 121 is opened on a portion of the first surface 126 and passes through the side surface 128. The arc groove 121 passes through the side surface 128, and thus both sides of the arc groove 121 are not completely closed. In other words, the arc groove 121 may be a semi-closed groove, and the corners of the photovoltaic panel 200 may be directly inserted into the arc groove 121 from the first surface 126. This arrangement may prevent the groove wall of the arc groove 121 from interfering with the installation of the photovoltaic panel 200.

[0058] It is understandable that the shapes and sizes of the multiple fixing members 120 and the shapes and sizes of the arc grooves 121 of the multiple fixing members 120 can be configured to be the same. One of the multiple fixing members 120 only needs to be flipped or rotated to change its position to replace the remaining fixing members 120. Exemplarily, the difference between the relatively arranged first fixing member 122 and the second fixing member 123 is only the direction of the arc groove 121. The first fixing member 122 only needs to be flipped and adjusted to change the direction of its own arc groove 121, that is, it can replace the second fixing member 123. This setting can improve the versatility between the fixing members 120, reduce material waste, and reduce the difficulty of packaging.

[0059] In one embodiment, please refer to Figure 3 , the side plate 114 may include a first side plate 114a and a second side plate 114b opposite to each other, and the length of the fixing member 120 is equal to the spacing between the first side plate 114a and the second side plate 114b. The two ends of the fixing member 120 may abut against the first side plate 114a and the second side plate 114b, and the first side plate 114a and the second side plate 114b may constrain the degree of freedom of the fixing member 120. In addition, under the action of other side plates 114 and the photovoltaic panel 200, the fixing member 120 can be stably restricted in the outer frame 110, and then the photovoltaic panel 200 can also be fixed in the outer frame 110. This arrangement prevents the photovoltaic panel 200 from colliding and tilting during transportation, which is conducive to improving the safety of the photovoltaic panel 200.

[0060] The photovoltaic panel 200 squeezes the fixing member 120 under the influence of gravity. The fixing member 120 is squeezed for a long time and deformed. The deformed fixing member 120 is not enough to support between the photovoltaic panel 200 and the outer frame 110. The photovoltaic panel 200 may hit the inner wall of the outer frame 110. In this embodiment, please continue to refer to Figure 3 , the packaging device 100 may also include at least one support member 130. The number of the support members 130 may be 1, 2, 3, etc., and this embodiment is not limited thereto. The support members 130 may be selected and designed according to the number of specific photovoltaic panels 200 and the weight of a single photovoltaic panel 200. The support member 130 is disposed on the bottom plate 112 and is located between the first fixing member 122 and the second fixing member 123. The support member 130 may have sufficient buffering performance and support, etc. The support member 130 may be used to support the photovoltaic panel 200. The support member 130 may provide a certain supporting force for the photovoltaic panel 200 to prevent the photovoltaic panel 200 from being affected by gravity and bumping against the inner wall of the outer frame 110. The support member 130 may also share the pressure of the fixing member 120 disposed under the photovoltaic panel 200, reduce the deformation of the fixing member 120, and increase the service life of the fixing member 120, so that the packaging device 100 can be suitable for long-term sealing or packaging.

[0061] The support member 130 may be foam or silicone. The foam has the characteristics of compression deformation resistance and flame retardancy, the foam has the characteristics of fire and moisture resistance, good energy absorption effect, etc., and the silicone has the characteristics of high temperature resistance, corrosion resistance, aging resistance, plasticity and adhesion, etc. The support member 130 is selected and designed according to the specific implementation scenario, and this implementation does not limit it.

[0062] Preferably, the thickness of the support member 130 can be configured to be thicker than that of the fixing member 120. The thicker support member 130 provides greater support force for the photovoltaic panel 200. Under the influence of the sizes of the support member 130 and the fixing member 120, the gravity of the photovoltaic panel 200 acts on the support member 130 first, and the support member 130 can provide sufficient support force for the photovoltaic panel 200.

[0063] In another embodiment, the support member 130 may be provided with a fixing groove (not shown in the figure), and the fixing groove may be adapted to the shape and size of the photovoltaic panel 200. The support member 130 not only supports the photovoltaic panel 200, but also has a certain fixing effect. This arrangement further improves the fixing effect of the packaging device 100 on the photovoltaic panel 200, and further improves the transportation safety of the photovoltaic panel 200.

[0064] In some other embodiments, the packaging device 100 may also be provided with a lifting belt (not shown in the figure), which may be a nylon belt, a metal lifting belt, etc. The lifting belt is wrapped around the circumference of the photovoltaic panel 200 and at least abuts against the end of the photovoltaic panel 200 close to the bottom plate 112. When it is necessary to take a plurality of photovoltaic panels 200 as a whole from the outer frame 110, the installer can directly lift the lifting belt, which will push the bottom of the photovoltaic panel 200 and lift the plurality of photovoltaic panels 200 out of the outer frame 110, thereby speeding up the installation and taking rate. At the same time, the transporter can preferentially install the plurality of photovoltaic panels 200 in the plurality of fixings 120, and then slowly put the plurality of photovoltaic panels 200 and the fixings 120 into the outer frame 110 through the lifting belt, and the lifting belt can also speed up the packaging rate.

[0065] To facilitate understanding and use of the packaging device 100, the following content introduces specific usage methods:

[0066] When packaging is required, the transport personnel can remove the top plate 113 of the outer frame 110, install the first fixing member 122, the second fixing member 123 and the support member 130 on the bottom plate 112, and make the first fixing member 122 and the second fixing member 123 abut against the side plate 114. Insert the photovoltaic panels 200 one by one into the arc grooves 121 of the first fixing member 122 and the second fixing member 123, and clamp the third fixing member 124 and the fourth fixing member 125 to the remaining corners of the plurality of photovoltaic panels 200. Install the top plate 113 on the side plate 114, and close the accommodating cavity 111 to complete the packaging of the photovoltaic panels 200.

[0067] When unpacking is required, the transport personnel can disassemble the top plate 113 of the outer frame 110, take out the third fixing member 124 and the fourth fixing member 125, and multiple photovoltaic panels 200 can be made available for subsequent installation personnel to take or use, thus completing the unpacking and use of the photovoltaic panels 200.

[0068] It is understandable that when multiple photovoltaic panels 200 are not fully used, the transportation personnel can put the third fixing member 124 and the fourth fixing member 125 again, and connect the top plate 113 with the side plate 114. The closed accommodating cavity 111 provided by the outer frame 110 is beneficial for the storage of the remaining photovoltaic panels 200.

[0069] The packaging device 100 provided in this embodiment is configured to fix the photovoltaic panel 200 to the arc grooves 121 of the plurality of fixing members 120 at the same time, and to arrange the plurality of fixing members 120 and the photovoltaic panel 200 in the accommodating cavity 111 together. The fixing members 120 can not only fix the photovoltaic panel 200 of the wave-shaped structure in the accommodating cavity 111, but also play a buffering role between the photovoltaic panel 200 and the outer frame 110, thereby protecting the use safety of the photovoltaic panel 200 and avoiding damage to the photovoltaic panel 200 due to impact and uneven force. At the same time, while the outer frame 110 protects the photovoltaic panel 200, its regular shape also facilitates transportation by transport personnel.

[0070] The above implementation modes are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned implementation modes, a person skilled in the art should understand that the technical solutions described in the aforementioned implementation modes can still be modified, or some of the technical features can be replaced by equivalents. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various implementation modes of the present application, and should all be included in the protection scope of the present application.
