[0040] In order to more clearly understand the above-mentioned purposes, features and advantages of the present disclosure, the solutions of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.
[0041] Many particular details are set forth in the following description in order to provide a thorough understanding of the present disclosure. However, the present disclosure can be practiced according to the claims without some or all of these details. Indeed, some embodiments of the present disclosure can be specifically adapted to the needs and particular circumstances of one or more of the particular parties.
[0042] Please refer to Figures 1 to 4 The support structure 100 provided by the embodiments of the present application can be applied to a photovoltaic module transfer vehicle. For example, the target position can be a loading frame of the photovoltaic module transfer vehicle, and the loading frame can be provided with a plurality of support structures 100 for supporting photovoltaic modules. The support structure 100 provided by the embodiments of the present application can also be used in other devices for supporting articles, which is not limited herein.
[0043] It should be noted that the support structure 100 provided by the embodiments of the present application can be applied to a photovoltaic module transfer vehicle, for example, the target position can be a loading frame of the photovoltaic module transfer vehicle, and the loading frame can be provided with a plurality of support structures 100 for supporting photovoltaic modules. The support structure 100 provided by the embodiments of the present application can also be used in other devices for supporting articles, which is not limited herein.
[0044] The first support member 11 and the second support member 12 are movably connected, and the extension or shortening of the telescopic unit 1 is realized by moving the first support member 11 relative to the second support member 12. After the telescopic unit 1 is extended, it is used to support devices such as photovoltaic modules. After the telescopic unit 1 is shortened, it is convenient for loading or unloading photovoltaic modules, avoiding collision with photovoltaic modules. Alternatively, the extension or shortening of the telescopic unit 1 can also be used to adapt to different working conditions for supporting photovoltaic modules.
[0045] Alternatively, the length of the telescopic unit 1 is the length along the moving direction of the second support member 12 relative to the first support member 11. As shown in Figure 1 As shown in Figure 3 As shown in
[0046] The first limiting unit 2 is rotatably installed in the first support 11 or the second support 12. The rotation of the first limiting unit 2 can be achieved by the structure design or by the driving device, which is not limited in the present application. When the second support 12 moves away from the target position to the required position relative to the first support 11, the first limiting unit 2 rotates to the first position to block the movement of the second support 12 towards the target position, limiting the length of the telescopic unit 1 to shorten; when the first limiting unit 2 rotates to the second position, the first limiting unit 2 no longer blocks the movement of the second support 12 towards the target position, so that the length of the telescopic unit 1 can be shortened. As shown in Figure 1 , when it is needed to load the photovoltaic module, the second support 12 can be pulled to move away from the target position relative to the first support 11, so that the length of the telescopic unit 1 is elongated, and the photovoltaic module is placed on the second support 12 to realize that the second support 12 supports the photovoltaic module. As shown in Figure 2 , after the telescopic unit 1 is elongated, the first limiting unit 2 rotates to the first position to block the movement of the second support 12 towards the target position, limiting the length of the telescopic unit 1 to shorten, thereby avoiding the photovoltaic module from falling or being damaged due to the movement of the second support 12 towards the target position caused by shaking or external force during the process of supporting the photovoltaic module by the second support 12.
[0047] As shown in Figure 4 , when it is not needed to load the photovoltaic module, the first limiting unit 2 can be rotated to the second position. As shown in Figure 3 , the second support 12 is pushed to move towards the target position relative to the first support 11, so that the length of the telescopic unit 1 is shortened to provide space for the photovoltaic module to be taken out or placed.
[0048] In the present application, the second support 12 is movably connected with the first support 11, so that the length of the telescopic unit 1 can be elongated or shortened as needed to elongate to support the target object such as the photovoltaic module or to shorten to reserve space for the target object to move, avoiding damage to the target object such as the photovoltaic module; the first limiting unit 2 is provided to prevent the telescopic unit from retracting after being elongated, thereby ensuring the stability of the support.
[0049] Please refer to Figure 5 , in some embodiments, one end of the telescopic direction of the telescopic unit 1 is rotatably installed at the target position; the telescopic unit 1 is configured to rotate relative to the target position to switch between the vertical state and the horizontal state;
[0050] When the telescopic unit 1 rotates relative to the target position to switch to the horizontal state, the elongation direction of the telescopic unit 1 intersects with the direction of gravity after the telescopic unit 1 is elongated, and the first limiting unit 2 rotates to the first position under the action of its own gravity;
[0051] When the telescopic unit 1 is switched to the vertical state by rotating relative to the target position, the first limiting unit 2 is rotated to the second position, and the second support 12 moves to the side of the first support 11 under the action of its own gravity, and the telescopic unit 1 is retracted.
[0052] It can be understood that the telescopic direction of the telescopic unit 1 is the relative movement direction of the first support 11 and the second support 12. The telescopic unit 1 is rotatably installed at the target position, so that the first support 11, the second support 12, and the first limiting unit 2 can be rotated relative to the target position as a whole. As shown in FIG. 1, the telescopic unit 1 is rotated to the horizontal state, and the telescopic direction of the telescopic unit 1 is the first direction X, which can be perpendicular to the direction Z of the gravity action, and the first support 11 and the second support 12 are horizontally arranged. As shown in FIG. 2, the telescopic unit 1 is rotated to the vertical state, and the telescopic direction of the telescopic unit 1 is switched to the second direction Y, which can be parallel to the direction Z of the gravity action, and the first support 11 and the second support 12 are vertically arranged. Figure 1 Figure 5 In the process of rotating the telescopic unit 1 and the first limiting unit 2 relative to the target position, the direction of the gravity acting on the telescopic unit 1 and the first limiting unit 2 does not change. When the telescopic unit 1 is switched to the horizontal state by rotating relative to the target position, the telescopic direction of the telescopic unit 1 intersects with the direction of the gravity action, and the relative position of the first support 11 and the second support 12 does not change due to the gravity action. The first limiting unit 2 is rotated to the first position under the action of its own gravity, that is, the first limiting unit 2 can be automatically rotated to the first position without other external force, thereby realizing the blocking action on the second support 12 and simplifying the operation steps.
[0053] When the telescopic unit 1 is switched to the vertical state by rotating relative to the target position, the first limiting unit 2 can be manually rotated to the second position, or driven to the second position by a driving device, or pushed to the second position by the structure design during the process of rotating the telescopic unit 1 from the horizontal state to the vertical state as a whole. Since the first limiting unit 2 no longer blocks the second support 12, the second support 12 moves to the target position under the action of its own gravity, the telescopic unit 1 is retracted, and the operation of moving the second support 12 is omitted. Compared with the telescopic unit 1 in the horizontal state, the telescopic unit 1 in the vertical state has a smaller volume, and more space can be reserved for the movement of the photovoltaic module.
[0054] When the telescopic unit 1 is switched to the vertical state by rotating relative to the target position, the first limiting unit 2 can be manually rotated to the second position, or driven to the second position by a driving device, or pushed to the second position by the structure design during the process of rotating the telescopic unit 1 from the horizontal state to the vertical state as a whole. Since the first limiting unit 2 no longer blocks the second support 12, the second support 12 moves to the target position under the action of its own gravity, the telescopic unit 1 is retracted, and the operation of moving the second support 12 is omitted. Compared with the telescopic unit 1 in the horizontal state, the telescopic unit 1 in the vertical state has a smaller volume, and more space can be reserved for the movement of the photovoltaic module.
[0055] In some embodiments, the first support 11 has a moving channel 111, one end of the second support 12 is movably mounted in the moving channel 111, and the first limiting unit 2 is rotatably mounted on one side wall 113 of the moving channel 111, and the rotation axis of the first limiting unit 2 is parallel to the moving direction of the second support 12 relative to the first support 11.
[0056] The first support 11 has a plurality of side walls 113, which enclose the moving channel 111. The second support 12 can move in the moving channel 111. In some embodiments, the extension direction of the moving channel 111 is the same as the extension direction of the telescopic unit 1.
[0057] The first limiting unit 2 is mounted on the first support 11, and the first limiting unit 2 is rotatably connected with any one of the plurality of side walls 113. The first limiting unit 2 can be rotatably connected with the side wall 113 through a rotation axis, and the axial direction of the first limiting unit 2 is the axial direction of the rotation axis. The axial direction of the first limiting unit 2 is parallel to the moving direction of the second support 12 relative to the first support 11, that is, the first limiting unit 2 can rotate around a direction parallel to the extension direction of the telescopic unit 1. When the first limiting unit 2 rotates to the first position, at least part of the first limiting unit 2 is located in the moving channel 111 to block the movement of the second support 12 towards the target position; when the first limiting unit 2 rotates to the second position, the first limiting unit 2 is located outside the moving channel 111, and the blocking of the second support 12 in the moving direction disappears to allow the second support 12 to move towards the target position.
[0058] In some embodiments, the first limiting unit 2 is rotatably mounted on the end of the side wall facing the target position, so as to facilitate the installation of the first limiting unit 2 and provide a rotation space for the first limiting unit 2; of course, in other embodiments, the first limiting unit 2 can be located at any position along the moving direction of the second support 12, but in this embodiment, an opening needs to be provided on the side wall for mounting the first limiting unit 2 and providing a rotation space for the first limiting unit 2, which is not limited in the present application.
[0059] In some embodiments, the first limiting unit 2 comprises a first connecting arm 21 and a mounting portion 22 connected with each other, the mounting portion 22 is rotatably connected with the first support 11, and the center of gravity of the first limiting unit 2 is located in the first connecting arm 21; when the telescopic unit 1 rotates to the transverse state and the telescopic unit 1 is extended, the first connecting arm 21 rotates to the first position under the action of its own gravity to limit the movement of the second support 12 towards one side of the first support 11.
[0060] The first connecting arm 21 and the mounting portion 22 can be integrally formed, and the first connecting arm 21 and the mounting portion 22 can rotate together around the axial direction of the mounting portion 22. The center of gravity of the first limiting unit 2 can be located at the first connecting arm 21 by adjusting the shape of the first connecting arm 21, the material density of the first connecting arm 21 and the mounting portion 22, and the like. When the telescopic unit 1 is rotated to the transverse state, the second supporting member 12 located in the moving channel 111 applies a supporting force to the first limiting unit 2, so that the first limiting unit 2 overcomes the gravity and is kept stationary and located outside the moving channel 111. The second supporting member 12 is driven to move relative to the first supporting member 11, the telescopic unit 1 is elongated, the first limiting unit 2 loses the support of the second supporting member 12, and the first connecting arm 21 is rotated to the first position under the action of its own gravity, so as to limit the movement of the second supporting member 12 to the target position.
[0061] By setting the first connecting arm 21 and the mounting portion 22 connected to each other, and setting the center of gravity of the first limiting unit 2 at the first connecting arm 21, the first limiting unit 2 can not only rotate relative to the first supporting member 11, but also automatically rotate to the first position under the action of its own gravity, thereby eliminating the operation of pulling the first limiting unit 2.
[0062] In some embodiments, the first connecting arm 21 has a protruding first blocking portion 23 on the side facing the moving channel 111, and is configured such that when the first limiting unit 2 is rotated to the first position, the first blocking portion 23 is located in the moving channel 111 and blocks the end of the second supporting member 12 close to the first supporting member 11, and when the first limiting unit 2 is rotated to the second position, the first blocking portion 23 is located outside the moving channel 111.
[0063] The first limiting unit 2 further comprises a first blocking portion 23, and the first blocking portion 23 and the first connecting arm 21 can be integrally formed. The first blocking portion 23 can be protrudingly arranged relative to the first connecting arm 21 towards the direction close to the moving channel 111, so that when the first connecting arm 21 is located outside the moving channel 111, the first blocking portion 23 can still be located in the moving channel 111. When the first limiting unit 2 is rotated to the first position, all or part of the first connecting arm 21 can be located outside the moving channel 111, and the first blocking portion 23 is located in the moving channel 111 to block the end of the second supporting member 12 close to the first supporting member 11. By setting the first blocking portion 23, it is ensured that the first limiting unit 2 can effectively block the second supporting member 12 at the first position.
[0064] In some embodiments, the first limiting unit 2 further includes a second connecting arm 24 connected to the mounting portion 22. The first connecting arm 21 and the second connecting arm 24 are asymmetrically arranged with respect to the center of the mounting portion 22 and extend along the side wall 113 opposite to the location of the first limiting unit 2. The second connecting arm 24 is configured to drive the first limiting unit 2 to rotate in the opposite direction to a second position by pushing the second connecting arm 24 during the rotation of the telescopic unit 1 from the horizontal state to the vertical state.
[0065] The first connecting arm 21, the second connecting arm 24, and the mounting part 22 can be integrally formed. The first connecting arm 21 and the second connecting arm 24 are asymmetrically arranged with respect to the center of the mounting part 22 to maintain the center of gravity of the first limiting unit 2 located at the first connecting arm 21.
[0066] Under the influence of gravity, the first connecting arm 21 rotates, and the mounting part 22 and the second connecting arm 24 rotate together. Figure 2 As shown, during the rotation of the telescopic unit 1 from a horizontal to a vertical state, all or part of the second connecting arm 24 is located outside the moving channel 111 to facilitate pushing the second connecting arm 24, thereby causing the first limiting unit 2 to rotate in the opposite direction to the second position, so that the second support member 12 can retract into the first support member 11 under the action of gravity. The "reverse rotation" of the first limiting unit 2 to the second position is relative to its rotation to the first position, and does not restrict whether the first limiting unit 2 rotates clockwise or counterclockwise. Optionally, when the telescopic unit 1 switches from a vertical to a horizontal state, the first limiting unit 2 rotates counterclockwise to the first position under the action of gravity; when the telescopic unit 1 switches from a horizontal state to a vertical state, the first limiting unit 2 rotates clockwise to the second position.
[0067] Optionally, when the first limiting unit 2 is in the first position, the extending direction of the second connecting arm 24 intersects with the reference plane where the side wall 113 of the first limiting unit 2 is installed.
[0068] In some embodiments, the first support 11 further includes a mounting arm 112 connected to the end of the moving channel 111 facing the target position;
[0069] A fixed unit 3 is provided at the target position. The mounting arm 112 is rotatably mounted on the fixed unit 3. During the process of the telescopic unit 1 rotating from the horizontal state to the vertical state, the second connecting arm 24 directly abuts against the fixed unit 3 or against the second blocking part 33 provided on the fixed unit 3, so as to push the first limiting unit 2 to rotate in the direction.
[0070] The mounting arms 112 are oppositely arranged and connected with two oppositely arranged side walls 113 in the moving channel respectively. The fixing unit 3 comprises oppositely arranged first fixing plates 31 and a second fixing plate 32 connecting the two first fixing plates 31, and the two oppositely arranged mounting arms 112 are rotatably connected with the two oppositely arranged first fixing plates 31 respectively. The second fixing plate 32 can be fixed with the target position, for example, the frame of the carrier. The second blocking part 33 can be mounted on the side of the second fixing plate 32 close to the second support 12, or can be part of the second fixing plate 32.
[0071] The side wall 113 connected with the first limiting unit 2 and the side wall 113 connected with the mounting arm 112 can be different side walls 113, so as to reduce the interference between the first limiting unit 2 and the mounting arm 112. Alternatively, as shown in Figure 3 The two first fixing plates 31 are oppositely arranged along the second direction Y, the second fixing plate 32 connects the two first fixing plates 31 along the second direction Y, and the two mounting arms 112 are oppositely arranged along the second direction Y. The telescopic unit 1 is in the transverse state, and the first limiting unit 2 is connected with the side wall 113 located at the top of the first support 11.
[0072] Please refer to Figure 5 and Figure 6 When the telescopic unit 1 rotates from the transverse state to the vertical state, the first support 11 rotates relative to the fixing unit 3, the first limiting unit 2 located on the first support 11 gradually approaches the second fixing plate 32 or the second blocking part 33, until the second connecting arm 24 directly abuts against the second fixing plate 32 or the second blocking part 33, and the first support 11 continues to rotate relative to the fixing unit 3. The second connecting arm 24 is forced by the second fixing plate 32 or the second blocking part 33, so that the first limiting part 4 rotates relative to the first support 11 to the second position. When the telescopic unit rotates to the vertical state, the first limiting part 4 is also located at the second position, and the second support 12 is retracted relative to the first support 11 under the action of gravity.
[0073] By arranging the fixing unit 3 abutting against the second connecting arm 24 during the rotation of the telescopic unit 1 from the transverse state to the vertical state, the first limiting unit 2 can rotate to the second position without other external force, so as to realize the shortening of the telescopic unit 1, greatly simplifying the operation steps and improving the work efficiency.
[0074] Please refer to Figure 1 word Figure 4 In some embodiments, the support structure 100 further comprises a first limiting part 4 for limiting the continued rotation of the first limiting unit 2 to the first position.
[0075] The first limiting unit 2 can be limited by the first limiting member 4 from continuing to rotate in the first rotation direction and deviating from the first position after the first limiting unit 2 rotates to the first position in the first rotation direction. During use of the support structure 100, the first limiting unit 2 can deviate from the first position due to external force, so that the second support member 12 loses the blocking of the first limiting unit 2. By arranging the first limiting member 4, the first limiting unit 2 can be limited from rotating in a certain direction to deviate from the first position, thereby improving the stability of the support structure 100 during use.
[0076] The first limiting member 4 is arranged on any one of the first support member 11 and the first limiting unit 2. In some embodiments, the first limiting member 4 is a third blocking portion 4a arranged on the first connecting arm 21, and configured to abut against the side wall 113 of the moving channel 111 when the first limiting unit 2 rotates to the first position, so as to limit the first limiting unit 2 from continuing to rotate.
[0077] The third blocking portion 4a and the first connecting arm 21 can be an integral molded part, or can be separately prepared. The first limiting member 4 can protrude away from the target position relative to the first connecting arm 21. When the first connecting arm 21 rotates to the first position, the first connecting arm 21 passes the end face of the side wall 113 until it rotates to the first position. Due to the protrusion of the third blocking portion 4a relative to the first connecting arm 21, the first connecting arm 21 cannot pass the end face of the side wall 113 and abut against the side wall 113, so as to limit the first limiting unit 2 from continuing to rotate.
[0078] Optionally, the third blocking portion 4a is a plate-shaped structure, and the third blocking portion 4a is arranged on the side of the first connecting arm 21 away from the moving channel 111. The third blocking portion 4a protrudes relative to the first connecting arm 21 along the extension direction of the extension unit 1.
[0079] In some embodiments, the support structure 100 further comprises a second limiting member 5 for limiting the first limiting unit 2 from continuing to rotate after rotating to the second position.
[0080] The second limiting member 5 can limit the first limiting unit 2 from continuing to rotate in the second rotation direction and deviating from the second position to return to the first position after the first limiting unit 2 rotates to the second position in the second rotation direction (the second rotation direction is opposite to the first rotation direction). During use of the support structure 100, the first limiting unit 2 can rotate to the first position due to external force deviating from the second position, so that the second support member 12 is blocked by the first limiting unit 2. By arranging the second limiting member 5, the first limiting unit 2 can be limited from rotating in a certain direction to deviate from the second position, thereby improving the stability of the support structure 100 during use.
[0081] The second limiting member 5 is arranged on any one of the first supporting member 11 and the first limiting unit 2. By arranging the first limiting member 4 and the second limiting member 5, the first limiting unit 2 can only reciprocate within the corresponding limiting range of the first limiting member 4 and the second limiting member 5, so as to avoid the first limiting unit 2 from rotating more than 360°, thereby ensuring that the first limiting unit 2 can stably realize automatic switching between the first position and the second position under the gravity of the first limiting unit 2 and the force applied by the fixing unit 3.
[0082] In some embodiments, the second limiting member 5 is a fourth blocking part 5a arranged on the side wall 113 of the moving channel 111, and is configured to abut against the fourth blocking part 5a when the first limiting unit 2 rotates to the second position, so as to limit the first limiting unit 2 from continuing to rotate in the reverse direction.
[0083] The fourth blocking part 5a can be arranged at the end of the side wall 113. When the first connecting arm 21 rotates to the first position, the first connecting arm 21 rotates along the first rotation direction to pass through the end surface of the side wall 113 until it rotates to the first position, and the second connecting arm 24 moves to the first position in the direction away from the moving channel 111 along the first direction X; when the second connecting arm 24 rotates to the second position, the second connecting arm 24 moves to the second position in the direction close to the moving channel 111 along the reverse direction of the first rotation direction, and abuts against the second limiting member 5 to limit the first limiting unit 2 from continuing to rotate in the reverse direction of the first rotation direction, while the first connecting arm 21 passes through the end surface of the side wall 113 along the reverse direction of the first rotation direction until it rotates to the second position.
[0084] In some embodiments, the support structure 100 further comprises a second limiting unit 6 for limiting the second supporting member 12 from separating from the first supporting member 11 after the telescopic unit 1 is extended.
[0085] The second supporting member 12 moves in the direction away from the target position, so that part of the second supporting member 12 extends out of the moving channel 111, and when the second supporting member 12 continues to move in the direction away from the target position, the second supporting member 12 will separate from the first supporting member 11. The second limiting unit 6 is arranged to limit the distance of the second supporting member 12 from the first supporting member 11, so as to avoid the second supporting member 12 from separating from the first supporting member 11.
[0086] In some embodiments, the second limiting unit 6 comprises a limiting slot 61 and a matching limiting block 62, the extending direction of the limiting slot 61 is parallel to the moving direction of the second supporting member 12; one of the limiting slot 61 and the limiting block 62 is arranged on the first supporting member 11, and the other is arranged on the second supporting member 12, and the limiting block 62 is located in the limiting slot 61, and when the telescopic unit 1 is extended, the limiting block 62 abuts against one end of the limiting slot 61 in the length direction.
[0087] For the convenience of description, the first support member 11 is provided with the limiting groove 61, and the second support member 12 is provided with the limiting block 62, which are taken as examples for description.
[0088] The limiting block 62 is arranged in the limiting groove 61, so that the limiting block 62 moves along the limiting groove 61, thereby guiding the second support member 12 to move along the extending direction of the limiting groove 61. When the second support member 12 moves away from the target position, the limiting block 62 moves along the limiting groove 61 with the second support member 12, until the limiting block 62 abuts against the end of the limiting groove 61, thereby limiting the continuous movement of the limiting block 62 and the second support member 12. In some embodiments, the telescopic unit 1 is extended or shortened, and the limiting block 62 moves in the limiting groove 61. The limiting groove 61 provides sufficient length for the movement of the limiting block 62. In some embodiments, the telescopic unit 1 is shortened, and the limiting block 62 can move along the limiting groove 61 to move out of the limiting groove 61; the telescopic unit 1 is extended, and the limiting block 62 moves in the direction close to the limiting groove 61 to move into the limiting groove 61, until abutting against one end of the length direction of the limiting groove 61.
[0089] Please refer to Figure 7 In some embodiments, the support structure 100 further comprises a sliding unit 7, at least one of the first support member 11 and the second support member 12 is connected with the sliding unit 7, and the sliding unit 7 is used for supporting the movement of the second support member 12 relative to the first support member 11.
[0090] The sliding unit 7 can be a roller, a pulley, a slide, etc. The sliding unit 7 is used for supporting the movement of the second support member 12 relative to the first support member 11, thereby reducing the frictional force of the relative movement of the first support member 11 and the second support member 12.
[0091] For example, the sliding unit 7 is a roller, and a plurality of rollers are arranged in sequence. The two ends of the roller are connected with the oppositely arranged side walls 113, and the second support member 12 is arranged on the plurality of rollers. When the second support member 12 moves relative to the first support member 11, the second support member 12 rubs against the plurality of rollers, thereby reducing the frictional force of the relative movement of the first support member 11 and the second support member 12.
[0092] For example, the sliding unit 7 is a pulley, and the pulley is arranged on the second support member 12. The second support member 12 is supported in the first support member 11 through the pulley. The pulley rolls to move the second support member 12 relative to the first support member 11, thereby reducing the frictional force of the relative movement of the first support member 11 and the second support member 12.
[0093] For example, the sliding unit 7 can also be a slide rail assembly between the first support member 11 and the second support member 11.
[0094] In a second aspect, a photovoltaic module transfer vehicle is provided. Please refer to Figures 8 to 11The photovoltaic module transfer vehicle comprises a loading frame 200 and a plurality of support arms arranged on the loading frame 200 and used for supporting the fixed photovoltaic module 300; the support arm adopts the support structure 100 provided in the first aspect.
[0095] The photovoltaic module transfer vehicle comprises the support structure 100 of any of the above embodiments. Since the support structure 100 adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.
[0096] The plurality of support structures 100 are arranged in the same reference plane to support the same photovoltaic module 300. The plurality of support structures 100 are arranged in layers in the vertical direction in sequence and spaced apart. Each layer of support structures 100 can be used to support different photovoltaic modules 300 arranged in the vertical direction. Optionally, the loading frame 200 comprises a plurality of columns 201, and the plurality of support structures 100 are arranged on the columns 201 in a spaced-apart manner through the fixing unit 3.
[0097] When loading the photovoltaic module 300 into the photovoltaic module transfer vehicle, the telescopic structure is first adjusted to the vertical state to reserve a larger space for moving the photovoltaic module 300. The photovoltaic module 300 enters the photovoltaic module transfer vehicle from the bottom of the photovoltaic module transfer vehicle and rises to a preset height in the vertical direction. The telescopic unit 1 of the support arm corresponding to the preset height is switched to the horizontal state so that the second support piece 12 extends below the photovoltaic module 300. The photovoltaic module 300 is placed on the second support piece 12 of the plurality of support structures 100.
[0098] The photovoltaic module 300 comprises a photovoltaic panel 301 and a photovoltaic support 302 supporting the photovoltaic panel 301. When the telescopic unit 1 is in the horizontal state, the photovoltaic support 302 can be placed in the mounting groove of the second support piece 12.
