Description

Technical Field

Detailed Implementation

[0017] The embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this disclosure, and should not be construed as limiting this disclosure.

[0018] Figure 1 and Figure 2 The deployed configurations of the container photovoltaic power generation system 100 in two different embodiments are illustrated.

[0019] According to some embodiments of this disclosure, such as Figure 1 or Figure 2 As shown, the containerized photovoltaic power generation system 100 includes a container body 10, a foldable support frame 20, and photovoltaic panels 22. The foldable support frame 20 has a folded configuration that can be stored inside the container body 10 and an unfolded configuration that can be unfolded outward from the container body 10. The foldable support frame 20 includes multiple frames 21, and the photovoltaic panels 22 are arranged on the frames 21.

[0020] In some embodiments of this disclosure, such as Figure 1 or Figure 2As shown, the container 10 includes a top cover 11, a bottom wall 112, a front wall, a rear wall, and a pair of end walls 13. The front wall and rear wall are spaced apart along a first direction Y, and the pair of end walls are spaced apart along a second direction X. The bottom wall 112, top cover 11, front wall, rear wall, and pair of end walls 13 constitute a closable storage space. At least one of the front wall and rear wall can be opened to facilitate the unfolding of the foldable support 20 outward and folding inward through the openable front or rear wall. Preferably, the container 10 can be formed from a standard shipping container.

[0021] In some embodiments of this disclosure, the foldable support 20 can be deployed in a folded configuration and an unfolded configuration. In the folded configuration, the foldable support 20 is folded up and stored in the storage space of the housing 10. In the unfolded configuration, the foldable support 20 is unfolded and removed from the housing 10. When the foldable support 20 is deployed in the unfolded configuration, the photovoltaic panels 22 arranged on the frame 21 can receive sunlight to generate electricity.

[0022] Please continue to refer to this. Figure 1 or Figure 2 The foldable bracket 20 can be folded along the first direction Y towards the housing 10 and unfolded away from the housing 10.

[0023] In some embodiments of this disclosure, the foldable support 20 includes a plurality of frames 21 arranged sequentially in a first direction Y, with adjacent frames 21 pivotally connected. For example, such as Figure 1 or Figure 2 As shown, each frame 21 has a bottom support 211 and a top support 212 opposite to and higher than the bottom support 211. Each pair of adjacent frames 21 forms a frame pair 27. The top supports 212 of the two frames 21 in the frame pair 27 are pivotally connected about a pivot extending in the second direction X. The bottom supports 211 of the two adjacent frames 21 in the adjacent frame pair 27 are pivotally connected about a pivot extending in the second direction X. The top of the frame pair 27 has limiting rods 26 on both sides extending in the second direction X away from the frame 21. Wherein, as... Figure 1 As shown, the second direction X is horizontal to the first direction Y. In other words, the second direction X is essentially a horizontal direction perpendicular to the first direction Y, and the first direction Y, the second direction X, and the vertical direction are all perpendicular to each other.

[0024] In some optional embodiments, the foldable bracket 20 may include four, eight, ten or other frames 21, but this disclosure is not limited thereto. The foldable bracket 20 may include other numbers of frames 21. The number of frames 21 can be reasonably set according to the actual situation such as the volume of the housing 10, the volume of the foldable bracket 20 in the folded configuration and the installation requirements.

[0025] In some embodiments of this disclosure, each frame 21 further includes a pair of side supports 213, which connect the bottom support 211 and the top support 212 along the second direction X. The pair of side supports 213 connect the two sides of the bottom support 211 and the top support 212, respectively. The bottom support 211, the top support 212, and the side supports 213 constitute a rectangular frame 21. One or more photovoltaic panels 22 are arranged laterally or longitudinally on the frame 21.

[0026] In some embodiments of this disclosure, the top supports 212 of every two frames 21 are rotatably connected by hinges 25, and the bottom supports 211 of adjacent frames 21 in two adjacent frame pairs 27 are also connected by hinges 25. When the foldable support 20 is deployed in the unfolded configuration, it is wave-shaped, with the top supports 212 forming crests and the bottom supports 211 forming troughs. The axis of rotation of the hinges 25 extends along a second direction X, allowing the foldable support 20 to extend and retract in the first direction Y. In the folded configuration, the foldable support 20 is folded into a compact, upright foldable support 20 that can be housed within the housing 10, reducing its volume and facilitating its movement. In the unfolded configuration, the foldable support 20 is fully unfolded, allowing the photovoltaic panels 22 on the frames 21 to be tilted to an ideal angle, maximizing the utilization of sunlight for power generation.

[0027] In some embodiments of this disclosure, the base support 211 may be provided with casters 24 to assist in the movement of the frame 21. In other words, the casters 24 are arranged at the troughs of the foldable support 20. In some embodiments, such as Figure 1 As shown, some of the movable wheels 24 are configured as wheels that can walk directly on the ground, and the drive structure 23 provides the rotational power for the movable wheels 24. The drive structure 23 may include a servo motor. In other embodiments, such as Figure 2 As shown, the movable wheel 24 is configured as a wheel that can move on the track.

[0028] In some embodiments of this disclosure, a limiting rod 26 is disposed at the top of the frame pair 27 and extends away from the foldable bracket 20 along the second direction X. Specifically, the limiting rod 26 extends a distance from both ends of the top of the frame pair 27 toward both sides of the foldable bracket 20. Each frame pair 27 has one limiting rod 26 at each end of its top. In other words, the limiting rod 26 is disposed at the crest of the foldable bracket 20. More specifically, the limiting rod 26 may be fixed to the end of the top support 212, or the upper end of the side support 213, or fixed to the hinge 25 near the side end of the frame pair 27 and extend upward in the second direction X toward the side support 213. When the foldable bracket 20 is in a folded configuration, the limiting rod 26 can be used to limit the foldable bracket 20 to maintain it in the folded configuration state.

[0029] According to some disclosed embodiments, the containerized photovoltaic power generation system 100 further includes a first holding mechanism 40. Along the second direction X, at least one side of the foldable support 20 is provided with the first holding mechanism 40. In one specific embodiment of the invention, the first holding mechanism 40 is disposed within the container body 10 and located on both sides of the foldable support 20 along the second direction X. The first holding mechanism 40 is adapted to limit the position of the limiting rod 26 in the folded configuration.

[0030] In some embodiments of this disclosure, please refer to Figure 3 and Figure 4 The first holding mechanism 40 includes a plurality of first limiting parts 42 arranged at intervals along the first direction Y. The first limiting parts 42 are configured to rotate along a rotation axis that is liftable in the vertical direction Z and extends in the second direction X. The first limiting parts 42 are configured to be pushed in the folding direction by the limiting rod 26 during the folding process from unfolded configuration to folded configuration, thereby avoiding the limiting rod 26, and to return to their original position after the limiting rod 26 passes the first limiting part 42. In the folded configuration, the first limiting parts 42 and the limiting rod 26 maintain a limiting engagement in the unfolding direction of the foldable bracket 20. Specifically, along the first direction Y, the first limiting parts 42 are located on the side of the limiting rod 26 away from the housing 10 (that is, the first limiting parts 42 are located on the side of the limiting rod 26 facing the unfolding direction), so that the first limiting parts 42 can block the limiting rod 26 from moving in the unfolding direction, thereby keeping the foldable bracket 20 in the folded configuration state.

[0031] In an optional embodiment of this disclosure, the number of first limiting portions 42 of the first holding mechanism 40 on one side is not less than the number of limiting rods 26 on one side of the foldable bracket 20. In a preferred embodiment, the number of first limiting portions 42 of the first holding mechanism 40 on one side is equal to the number of limiting rods 26 on one side of the foldable bracket 20. When the foldable bracket 20 is deployed in a folded configuration, each first limiting portion 42 can block one limiting rod 26 from moving in the unfolding direction. The first limiting portion 42 can abut against the limiting rod 26 to prevent the foldable bracket 20 from swaying and the frames 21 from colliding with each other during the transportation of the container photovoltaic power generation system 100.

[0032] The first limiting part 42 can rotate to either a clearance position for avoiding the limiting rod 26 or a limiting position for limiting the limiting rod 26. The first limiting part 42 is configured to rotate to the clearance position during the movement of the foldable bracket 20 from the unfolded state to the folded state, and the first limiting part 42 is also configured to rotate to the limiting position when the foldable bracket 20 has moved to the folded state. The first limiting part 42 is rotatably disposed in the first holding mechanism 40 and can be used to avoid the limiting rod 26 during the folding operation, so that the multiple limiting rods 26 can move sequentially along the folding direction. In the folded configuration, the multiple first limiting parts 42 and the multiple limiting rods 26 are correspondingly limited and engaged to restrict the movement of the multiple frames 21 in the unfolding direction, thereby keeping the foldable bracket 20 in the folded configuration.

[0033] In an optional embodiment, the first limiting part 42 can be driven to rotate to the avoidance position by the limiting rod 26 pushing the first limiting part 42 in the folding direction.

[0034] In an optional embodiment, the first limiting part 42 is reset to the limiting position by its own weight or by setting a structure such as a torsion spring.

[0035] In a preferred embodiment, the first limiting portion 42 is configured to be pushed away from the limiting rod 26 in the folding direction during the folding process from the unfolded configuration to the folded configuration, and to reset after the limiting rod 26 passes the first limiting portion 42. In the folded configuration, the first limiting portion 42 remains in front of the limiting rod 26 in the unfolding direction of the foldable bracket 20. In some embodiments of this disclosure, "in front" is defined as the unfolding direction. Specifically, during the folding of the foldable bracket 20 in the folding direction, the limiting rod 26 moves in the folding direction and rises to contact the first limiting portion 42. The limiting rod 26 pushes the first limiting portion 42, causing the first limiting portion 42 to rotate in the folding direction. When the first limiting portion 42 rotates to a sufficient angle, the limiting rod 26 passes the first limiting portion 42, and the first limiting portion 42 separates from the limiting rod 26 and resets. Relative to the unfolding direction, the reset first limiting portion 42 is in front of the limiting rod 26. When the foldable bracket 20 is fully folded, each limiting rod 26 extends beyond the corresponding first limiting part 42, and each limiting rod 26 has a first limiting part 42 in front of it.

[0036] In other alternative embodiments, the rotation and reset of the first limiting part 42 can be achieved by providing a driving component such as a motor.

[0037] However, this disclosure is not limited thereto. In other embodiments disclosed, the rotation and reset of the first limiting part 42 can also be achieved in other ways. The first limiting part 42 is configured to rotate to an avoidance position during the movement of the foldable bracket 20 from the unfolded state to the folded state, and the first limiting part 42 is also configured to rotate to a limiting position when the foldable bracket 20 moves to the folded state.

[0038] Therefore, when the foldable bracket 20 moves to the folded configuration along the folding direction, the first limiting part 42 can rotate to the limiting position to limit the limiting rod 26, thereby keeping the foldable bracket 20 in the folded configuration. This allows for automatic locking and storage of the foldable bracket 20, eliminating the need for operators to manually lock and limit the foldable bracket 20 when it has moved to the folded state. Especially when storing a large number of foldable brackets 20, simply driving the foldable bracket 20 to the folded state is sufficient to lock it, greatly reducing the labor intensity of operators and improving the folding and storage efficiency of the foldable bracket 20.

[0039] When the foldable bracket 20 is unfolded from the folded configuration to the unfolded configuration, the first limiting part 42 can be raised above the limiting rod 26 in advance, thereby releasing the obstruction of the limiting rod 26 by the first limiting part 42, so that the foldable bracket 20 can be automatically unfolded to the unfolded configuration.

[0040] According to some embodiments of this disclosure, such as Figure 3 and Figure 4 As shown, the first holding mechanism 40 also includes a first beam 41, which extends along the first direction Y and is vertically and vertically movable within the housing 10. Multiple first limiting parts 42 are provided on the first beam 41 and arranged sequentially at intervals along the first direction Y. The first beam 41 can drive the multiple first limiting parts 42 to reciprocate synchronously along the vertical direction Z, so that the first limiting parts 42 selectively limit or separate from the corresponding limiting rod 26. The second direction X, the first direction Y, and the vertical direction Z are perpendicular to each other. The first direction is... Figure 3 In the Y direction, and Figure 4 The direction indicated by the Y-direction arrow is the folding direction of the foldable bracket 20. The second direction X, the first direction Y, and the vertical direction Z are perpendicular to each other.

[0041] The first retaining mechanism 40 is supported at a high position within the housing 10. When the foldable bracket 20 is folded, the first retaining mechanism 40 is positioned high enough to engage with the limiting rod 26 at the top of the frame 27. For example, along the second direction X, support mounting brackets 12 are provided on both sides of the foldable bracket 20 within the housing 10, and each support mounting bracket 12 on one side has a first retaining mechanism 40 at its top. The support mounting bracket 12 includes a mounting beam 123 extending along the first direction Y and a longitudinal beam 121 extending along the vertical direction Z. The longitudinal beam 121 and the mounting beam 123 are fixedly connected to support the mounting beam 123. The first retaining mechanism 40 can be mounted on the side of the mounting beam 123.

[0042] Exemplarily, the first beam 41 can be connected to the mounting beam 123, and the first beam 41 is movable relative to the mounting beam 123 in the vertical Z direction. For example, the first beam 41 and the mounting beam 123 can be movably connected by a slide rail, or the first beam 41 and the mounting beam 123 can be connected by a linear bearing 61, but this disclosure is not limited thereto. The first beam 41 and the mounting beam 123 can also be movably connected in other ways, wherein the first beam 41 extends in the first direction Y and is movably disposed in the housing 10 in the vertical direction.

[0043] For example, such as Figure 4As shown, the first holding mechanism 40 also includes a first driving part 43, which drives the first beam 41 to reciprocate in the vertical direction. The first driving part 43 is mounted on the mounting beam 123, and its driving end is connected to the first beam 41. The first driving part 43 may include a structure of the type of drive motor, electric cylinder, hydraulic cylinder, pneumatic cylinder, etc. The first driving part 43 drives the first beam 41 to reciprocate in the vertical Z direction, thereby raising and lowering the first limiting part 42. For example, when folding the foldable bracket 20, the first driving part 43 drives the first limiting part 42 to descend to the movement path of the limiting rod 26. When it is necessary to unfold the foldable bracket 20, the first driving part 43 drives the first limiting part 42 to rise above the height of the limiting rod 26, so that the first limiting part 42 separates from the limiting rod 26.

[0044] According to some embodiments of this disclosure, a plurality of first limiting portions 42 are rotatably disposed on the first beam 41 and arranged sequentially at intervals along the first direction Y. The first limiting portions 42 and the first beam 41 can be rotatably connected by pins, hinges, etc. However, this disclosure is not limited to this; the first limiting portions 42 and the first beam 41 can also be connected in other ways, wherein a plurality of first limiting portions 42 are disposed on the first beam 41 and arranged sequentially at intervals along the first direction Y. The plurality of first limiting portions 42 can correspond one-to-one with a plurality of frames 21 for limiting and positioning, so as to limit the foldable bracket 20 to a folded state.

[0045] In some embodiments of this disclosure, the first limiting part 42 includes a limiting part body 421, a limiting structure 425 connected to the limiting part body 421, and a limiting structure 422 connected to the limiting part body 421. The limiting part body 421 is hinged to the first beam 41. In the unfolding direction of the foldable bracket 20, the limiting structure 425 is located in front of the rotation axis of the first limiting part 42, and the limiting structure 422 is located behind the rotation axis of the first limiting part 42. The limiting structure 425 and the limiting structure 422 extend upward respectively, and the limiting structure 425 abuts against the first beam 41 under its own weight.

[0046] Preferably, the limiting part body 421 is rotatably connected to the first beam 41 by a pin, and the pin extends along the second direction X, so that the first limiting part 42 can rotate about the rotation axis extending in the second direction X.

[0047] In one specific embodiment, the first limiting part 42 is configured such that its center of gravity is located behind the rotation axis of the first limiting part 42 in the unfolding direction of the foldable bracket 20. In its natural state, the first limiting part 42 is in the state where the rotation limiting structure 425 abuts against the first beam 41. When the limiting rod 26 is pushed and completely passes through the first limiting part 42, the first limiting part 42 automatically resets under the action of gravity, and in the reset state, the rotation limiting structure 425 abuts against the first beam 41, restricting the first limiting part 42 from continuing to rotate. At this time, the limiting structure 422 remains in front of the limiting rod 26, preventing the limiting rod 26 from moving in the unfolding direction, thereby keeping the frame 21 in a folded state.

[0048] The first limiting part 42 is preferably located below the first beam 41. The limiting and rotating structure 425 extends upward in the vertical direction and can abut against the bottom of the first beam 41 in its natural state.

[0049] In one specific embodiment, the first limiting portion 42 can be formed by bending a metal sheet.

[0050] In some specific embodiments, such as Figure 5 As shown, a downward-opening clearance space 423 is formed on the lower side of the first beam 41. The clearance space 423 corresponds to the limiting structure 422. When the first limiting part 42 rotates in the folding direction, the limiting structure 422 can extend into the clearance space 423. The clearance space 423 is formed on the lower side of the first beam 41. The clearance space 423 corresponds to the limiting structure 422. When the first limiting part 42 rotates in the folding direction, the limiting structure 422 can extend into the clearance space 423, increasing the rotatable angle of the first limiting part 42 in the folding direction, thereby effectively avoiding the limiting rod 26, so that the limiting rod 26 can move smoothly in the folding direction.

[0051] In some specific embodiments, a guide slope 424 is formed on the lower surface of the limiting part body 421. The guide slope 424 extends downwards in the direction from the limiting part body 421 to the limiting structure 422. During the movement of the multiple frames 21 in the folding direction, the guide slope 424 is adapted to abut against the foldable bracket 20, so that the first limiting part 42 rotates in the folding direction. In the reset state of the first limiting part 42, the guide slope 424 is inclined relative to the vertical direction Z towards the folding direction, reducing the angle required for the limiting rod 26 to push the first limiting part 42 when it passes through it.

[0052] In some specific embodiments, the end of the limiting part body 421 that is away from the limiting structure 422 is connected to the rotation limiting structure 425. The rotation limiting structure 425 is adapted to cooperate with the first beam 41 to limit the first limiting part 42 from rotating in the unfolding direction.

[0053] According to some embodiments of this disclosure, such as Figure 1 and Figure 4 As shown, the container photovoltaic power generation system 100 also includes a second holding mechanism 50, which is located inside the container 10. The first holding mechanism 40 and the second holding mechanism 50 are selectively limited or separated from the corresponding limiting rods 26 to selectively limit the foldable bracket 20 to a folded state. The first holding mechanism 40 and the second holding mechanism 50 cooperate to unfold the multiple frames 21 in a preset sequence.

[0054] In some embodiments of this disclosure, a second holding mechanism 50 is disposed within the housing 10. The second holding mechanism 50 includes a plurality of second limiting portions 51 spaced apart along a first direction Y. The number of second limiting portions 51 is less than the number of first limiting portions 42. The second limiting portions 51 are configured to lift independently relative to the first limiting portions 42. The second limiting portions 51 correspond to portions of the first limiting portions 42 in the second direction X. In the folded configuration and in the unfolding direction, the second limiting portions 51 are respectively held in front of the limiting rod 26.

[0055] Along the second direction X, the second retaining mechanism 50 is located at a higher position on both sides of the foldable bracket 20, and is positioned high enough to engage with the limiting rod 26 at the top of the frame pair 27 when the foldable bracket 20 is folded. Exemplarily, the second retaining mechanism 50 may be mounted on the support mounting bracket 12.

[0056] The number of second limiting portions 51 is less than the number of first limiting portions 42, and the second limiting portions 51 correspond to portions of the first limiting portions 42 in the second direction X. In the folded configuration, by lowering the second limiting portions 51, the second limiting portions 51 can fall in front of some of the limiting rods 26 in the unfolding direction, causing some of the limiting rods 26 to be limited by both the first limiting portions 42 and the second limiting portions 51, while other portions of the limiting rods 26 are limited only by the first limiting portion 42. Raising the first limiting portion 42 and keeping the second limiting portion 51 stationary releases the restriction of the first limiting portion 42 on all the limiting rods 26, while maintaining the restriction of the second limiting portion 51 on some of the limiting rods 26. Therefore, the frame 21 limited only by the first limiting portion 42 can be unfolded first. Raising the second limiting portion 51 unfolds the remaining frame 21. Some embodiments of this disclosure delay the unfolding of a portion of the frame 21 by delaying the raising of the second limiting portion 51, thereby preventing the huge inertial impact caused by the simultaneous release of all frames 21.

[0057] Preferably, along the unfolding direction of the foldable bracket 20, a plurality of first limiting portions 42 arranged consecutively starting from the first first limiting portion 42 correspond one-to-one with a plurality of second limiting portions 51. That is, along the folding direction, the second limiting portion 51 corresponds one-to-one with the last first limiting portion 42 and a plurality of consecutively arranged first limiting portions 42 counting from the last first limiting portion 42 in the unfolding direction. In other words, the first limiting portions 42 not corresponding to the second limiting portion 51 are arranged consecutively, the first limiting portions 42 corresponding to the second limiting portion 51 are arranged consecutively, and all the first limiting portions 42 not corresponding to the second limiting portion 51 are located in front of the first limiting portions 42 corresponding to the second limiting portion 51. When unfolding the foldable bracket 20, the first beam 41 is raised first, so that all the first limiting parts 42 and all the limiting rods 26 are released from their limits. A portion of the frame 21 in front of the first limiting part 42 corresponding to the second limiting part 51 is unfolded first. As the second holding mechanism 50 is gradually raised, the second limiting part 51 and the limiting rods 26 corresponding to the first limiting part 42 are gradually released from their limits, so that the remaining frame 21 behind the first limiting part 42 that does not correspond to the second limiting part 51 is unfolded later.

[0058] In some embodiments of this disclosure, the lower ends of a plurality of second limiting portions 51 arranged upward in the first direction Y are sequentially raised along the unfolding direction. In this embodiment, the lower ends of the second limiting portions 51 are located at different heights, and the lower ends of the second limiting portions 51 that are further forward in the unfolding direction are higher. This arrangement allows the limiting rods 26 restricted by the second limiting portions 51 to be released in stages. Specifically, by raising the second limiting portions 51 in stages, each time the second limiting portion 51 is raised, the second limiting portion 51 with the higher lower end position first separates from the corresponding limiting rod 26, while the second limiting portion 51 with the lower lower end position continues to be limited and engaged with the limiting rod 26, until all the limiting rods 26 restricted by the second holding mechanism 50 are released, and the foldable bracket 20 is fully unfolded.

[0059] In some embodiments of this disclosure, the second limiting portion 51 is configured to extend upward in the vertical direction Z. Exemplarily, the second limiting portion 51 is configured as a plate extending upward in the vertical direction Z.

[0060] According to some embodiments of this disclosure, such as Figure 4 As shown, the second holding mechanism 50 also includes a second beam 52, which extends along a first direction and is movably disposed within the housing 10 in a vertical direction. Multiple second limiting parts 51 are disposed on the second beam 52, and the second beam 52 can drive the multiple second limiting parts 51 to reciprocate synchronously in a vertical direction. The second beam 52 can be connected to the mounting beam 123. The second beam 52 and the first beam 41 extend parallel to each other in the first direction Y upward and are spaced apart in the second direction X upward.

[0061] In some embodiments of this disclosure, the second holding mechanism 50 further includes a second driving part 53, which drives the second beam 52 to reciprocate along the vertical direction Z. Exemplarily, the second driving part 53 may include a drive motor, electric cylinder, hydraulic cylinder, pneumatic cylinder, or similar structure, which can be reasonably selected and configured according to actual conditions. The second driving part 53 may be fixed to the mounting beam 123, such that the second driving part 53 is located in the housing 10 and is fixedly connected to the second beam 52. By having the second driving part 53 located in the housing 10, it drives the second beam 52 to reciprocate along the vertical direction, thereby enabling selective limiting and separation of the second limiting part 51 and the foldable bracket 20, thus achieving the folding and unfolding of the foldable bracket 20.

[0062] Furthermore, such as Figure 6 and Figure 7 As shown, both the first retaining mechanism 40 and the second retaining mechanism 50 are provided with guide structures 60. There can be multiple guide structures 60, arranged along the first direction Y. The guide structures 60 are used to limit the linear movement of the first beam 41 and the second beam 52 in the vertical direction Z. For example, the guide structure 60 includes a linear bearing 61 and a linear guide rail 62. The linear bearing 61 is fixed to the mounting beam 123 and extends along the vertical direction Z. The corresponding linear guide rail 62 passes through the corresponding linear bearing 61, and the corresponding linear guide rail 62 is fixedly connected to the first beam 41 and the second beam 52 respectively. A first connecting plate 426 is fixedly mounted on the upper end of the first beam 41, and a corresponding linear guide rail 62 is connected to the first connecting plate 426. A second connecting plate 54 is fixedly mounted on the upper end of the second beam 52, and a corresponding linear guide rail 62 is connected to the second connecting plate 54. The corresponding linear guide rail 62 moves back and forth in the vertical direction within the corresponding linear bearing 61 to limit the movement trajectory of the first beam 41 and the second beam 52 in the vertical direction, thereby avoiding the offset and movement of the first beam 41 and the second beam 52, improving mechanical precision, and thus helping to ensure the safety and reliability of the foldable bracket 20 during the folding and unfolding process.

[0063] One or more foldable supports 20 may be installed inside the housing 10. For example... Figure 3 As shown, one end of the foldable bracket 20 can be fixed to the fixing beam 122 inside the housing 10, and the other end can unfold outward from the housing 10. Specifically, as... Figure 8 As shown, a foldable support 20 can be provided inside the housing 10 along the first direction Y, and this foldable support 20 can be unfolded outward from one side of the housing 10. For a larger housing 10, the housing 10 can also have two foldable supports 20 arranged in the second direction X, and these two foldable supports 20 can be unfolded outward from one side of the housing 10 along the first direction Y. Figure 9As shown, the housing 10 may contain two foldable supports 20 arranged in the first direction Y. These two foldable supports 20 unfold outward from opposite sides of the housing 10 along the first direction Y. In some other embodiments, the housing 10 contains four foldable supports 20, which can unfold outward in pairs from opposite sides of the housing 10 along the first direction Y.
