Description

Technical Field

[0001] This utility model belongs to the field of plate-shaped object installation technology, specifically relating to a control mechanism for unfolding and stacking plate-shaped objects. Background Art

[0002] In real life, we often encounter common flat, plate-like objects that are displayed flat during use but need to be folded and stacked for storage in certain situations. Examples include photovoltaic panels, advertising screens, or reflectors.

[0003] Photovoltaic panels are commonly used in photovoltaic (PV) power generation. PV power generation typically requires a large amount of space to install these panels. Therefore, the preferred location for PV power generation systems is a sparsely populated but well-lit area, such as deserts or wastelands. However, deserts or wastelands are also prone to sandstorms, which can easily damage PV panels. Furthermore, PV panels, when unfolded, have a large surface area and high wind resistance, making them ill-suited to withstand sandstorms. Similarly, common advertising screens and reflectors also occupy a large area when in use, and need to be stacked and stored to reduce their space requirements when not in use.

[0004] Therefore, there is an urgent need for a control mechanism to enable these plate-like objects to unfold and stack in different states. Utility Model Content

[0005] In order to address the lack of simultaneous unfolding or stacking functionality in existing support mechanisms for placing plate-shaped objects, the present invention aims to provide a control mechanism for unfolding and stacking plate-shaped objects.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A control mechanism for unfolding and stacking plate-shaped objects includes a telescopic arm, a translation control component, and plate-shaped objects. The telescopic arm is composed of several telescopic arm units, which intersect each other and are connected end to end to form several prismatic telescopic frames. Plate-shaped objects are installed on the telescopic arm units. Two telescopic arm units at one end of the telescopic arm are installed on the translation control component. The translation control component drives the two telescopic arm units at the end to move closer or further apart, thereby causing the telescopic arm to extend or retract.

[0008] Optionally, the translation control assembly is mounted on the support rod.

[0009] Optionally, a mounting bracket can be rotatably mounted on the support rod, and a mounting seat can be rotatably mounted on the mounting bracket; one telescopic arm unit at the end of the telescopic arm can be rotatably mounted on the mounting seat, and the other telescopic arm unit can be rotatably mounted on the translation control assembly.

[0010] Optionally, the translation control assembly includes a third drive motor, a ball screw, and a screw nut. The third drive motor drives the ball screw to rotate, thereby driving the screw nut to move along the axis of the ball screw, which in turn causes the two telescopic arm units at the ends of the telescopic arm to move closer to or further away from each other.

[0011] Optionally, the mounting base is fixedly mounted on the deflection shaft, and both ends of the deflection shaft are rotatably mounted on the mounting bracket. A second drive motor is mounted on the mounting bracket, and the second drive motor is used to drive the deflection shaft to rotate.

[0012] Optionally, the mounting base is equipped with a drive wheel and a drive chain, which drives the counterweight to move in the opposite direction to the movement of the lead screw and nut.

[0013] Optionally, the telescopic arm unit has several mounting holes, and the plate-like object has several mounting shafts, which are installed in the mounting holes.

[0014] Optionally, several telescopic arms are arranged in parallel on the translation control component, and the several telescopic arms together provide support for the plate-shaped object.

[0015] Optionally, a support frame is installed on the telescopic boom unit, and a plate is mounted on the support frame.

[0016] Alternatively, the plate-shaped object can be a photovoltaic panel, a reflector, or an advertising screen.

[0017] The beneficial effects of the utility model are:

[0018] This utility model provides a control mechanism for unfolding and stacking plate-shaped objects. By mounting the plate-shaped objects on a telescopic arm, which is composed of several prismatic telescopic frames formed by telescopic arm units, the plate-shaped objects unfold when the telescopic arm extends and stack when the telescopic arm retracts, thereby greatly reducing space occupation.

[0019] When the plate-shaped object in this utility model is a photovoltaic panel, when the telescopic arm is extended, multiple photovoltaic panels are extended to maximize the area, so that they can be used normally for photovoltaic power generation. When encountering wind and sand, the telescopic arm is retracted and all the photovoltaic panels are stacked together, reducing the area of ​​contact between the photovoltaic panels and the wind and sand, thereby reducing or preventing damage to the photovoltaic panels by wind and sand, and greatly reducing the impact of wind and sand on the photovoltaic power generation system.

[0020] When used as a promotional screen, this invention allows the screen to expand after the telescopic arm is extended, thus enabling the display of images. In rainy, snowy, or windy conditions, the telescopic arm retracts, and the screen is stacked, reducing the impact of the environment on the promotional screen and extending its service life.

[0021] Reflectors are typically used to reflect solar energy to generate solar thermal power. In rainy or snowy weather, reflectors can also be stacked using telescopic arms to reduce the impact of adverse environmental conditions on them. Attached Figure Description

DETAILED DESCRIPTION

[0036] Example 1:

[0037] In this embodiment, as Figures 1-3 The control mechanism shown is for unfolding and stacking plate-shaped objects. It includes a telescopic arm 700, a translation control component 600, and a plate-shaped object 800. The telescopic arm 700 is mounted on a support rod 101, which is mounted on the ground. Of course, the installation position of the support rod 101 is not considered a limitation of this utility model, and its installation position can be flexibly changed according to the actual application scenario.

[0038] In this embodiment, as Figures 1-5 As shown, the telescopic arm 700 is composed of several telescopic arm units 701, which intersect and are connected end-to-end to form a rhomboid telescopic frame. Plates 800 are mounted on the telescopic arm units 701. Two telescopic arm units 701 at one end of the telescopic arm 700 are mounted on a translation control component 600. The translation control component 600 moves the two telescopic arm units 701 at the end closer to or further away from each other, thus extending or retracting the telescopic arm 700. When the telescopic arm 700 extends, the plates 800 unfold, increasing their area, thus making them applicable to photovoltaic power generation. When the telescopic arm 700 retracts, the plates 800 stack together (e.g., ...). Figure 1 As shown in the figure, this greatly reduces the contact area between the plate 800 and the wind and sand, thereby greatly reducing the impact of wind and sand on the photovoltaic power generation system and reducing the damage of wind and sand to the plate.

[0039] When used as a promotional screen, the telescopic arm 700 unfolds, expanding the screen to display images. In rainy, snowy, or windy conditions, the telescopic arm 700 retracts, stacking the screen and reducing the impact of the environment, thus extending its lifespan.

[0040] Reflectors are typically used to reflect solar energy to generate solar thermal power. In rainy or snowy weather, reflectors can also be stacked using a telescopic arm 700 to reduce the impact of adverse environmental conditions on them.

[0041] In this embodiment, as Figures 6-9 As shown, the telescopic boom 700 includes several telescopic boom units 701 that are intersected and rotatably connected together. Adjacent telescopic boom units 701 are rotatably connected end to end. Two intersecting telescopic boom units 701 are hinged together at the middle, and two telescopic boom units 701 that are connected end to end are rotatably connected, thereby forming a plurality of telescopic boom units 701 as shown in the figure. Figures 4-6 The illustrated rhomboid telescopic frame has two telescopic arm units 701 at its outermost ends driven to move closer or further apart via a translation control assembly 600, thus changing the length of the rhomboid diagonal. One end of one of the telescopic arm units 701 is rotatably mounted on a mounting base 410 (e.g., Figure 5 As shown), another telescopic arm unit 701 can move along the length of the mounting base 410.

[0042] In this embodiment, as Figure 5 As shown, the telescopic arm 700 has several mounting holes 710, and one end of the plate 800 is provided with a mounting shaft (not shown in the figure), which is installed in the mounting hole 710.

[0043] In this embodiment, the translation control component 600 includes a third drive motor 611, a second ball screw 612, and a screw nut 613.

[0044] In this embodiment, as Figure 5 As shown, the two telescopic arm units 701 closest to the support rod 101 of the telescopic arm 700 are respectively rotatably mounted on the translation mechanism composed of the ball screw 612 and the screw nut 613, and the other is rotatably mounted on the mounting base 410.

[0045] In this embodiment, as Figure 4 and Figure 5 As shown, the mounting base 410 includes two parallel long mounting plates. A ball screw 612 is parallelly disposed between the two long mounting plates. The telescopic arm unit 701 is hinged to one end of the long mounting plate. The two ends of the two long mounting plates are connected by short mounting plates. The two ends of the ball screw 612 are rotatably mounted on the short mounting plates. A third drive motor 611 is disposed on one of the short mounting plates and is drively connected to the ball screw 612. A screw nut 613 is mounted on the ball screw 612 and is hinged to the telescopic arm unit 701.

[0046] As the lead screw nut 613 moves along the ball screw 612, the telescopic arm 700 extends or retracts.

[0047] In this embodiment, as Figure 4 and Figure 5 As shown, two long mounting plates are rotatably connected to both sides of the top of the mounting bracket 310 via a deflection shaft 413, but the deflection shaft 413 is fixedly connected to the two long mounting plates. A second fixed gear 411 is fixedly installed on the deflection shaft 413, and a second drive motor 313 is installed on the mounting bracket 310. The second drive motor 313 is connected to the second fixed gear 411 for transmission. The second drive motor 313 drives the deflection shaft 413 to rotate through the second fixed gear 411, thereby driving the mounting base 410 to rotate.

[0048] In this embodiment, as Figures 4-5 As shown, a third fixed gear 201 is provided at the top of the support rod 101. The top of the support rod 101 is rotatably mounted at the bottom center of the mounting bracket 310, and the bottom of the mounting bracket 310 passes through the center of the third fixed gear 201. A first drive motor 311 is also mounted on the mounting bracket 310. The power output shaft of the first drive motor 311 passes through the mounting bracket 310 and is connected to the third fixed gear 201 for transmission, so that the first drive motor 311 drives the entire mounting bracket 310 to rotate around the axis of the third fixed gear 201.

[0049] In this embodiment, the axis of the third fixed gear 201 forms the Z-axis, the deflection shaft 413 forms the Y-axis, and the axis of the ball screw 612 forms the X-axis. That is, the first drive motor 311 drives the mounting bracket 310 and its mounting seat 410 to rotate around the Z-axis, the second drive motor 313 drives the mounting seat 410 to rotate around the Y-axis; the third drive motor 611 drives the extension and retraction of the telescopic arm 700, thereby causing the plate-shaped object 800 on the telescopic arm unit 701 to unfold or stack.

[0050] This embodiment is applicable to adjusting the angle of a plate-shaped object so that the plate-shaped object can always maintain the optimal angle of sunlight incidence, thereby ensuring photovoltaic power generation efficiency.

[0051] Meanwhile, in photovoltaic power generation areas such as adjacent areas or deserts, there is often a lot of wind and sand, which can easily damage the plate-shaped objects. The telescopic arm of this utility model can also retract the plate-shaped objects and stack them (e.g. Figure 8 (As shown), thereby reducing the damage of wind and sand to slab-shaped objects.

[0052] In this embodiment, two sets of telescopic arms 700 are arranged in parallel on the translation control component 600, and the two sets of telescopic arms 700 together support the plate-shaped object 800.

[0053] In other embodiments, multiple sets (three or more sets) of telescopic arms 700 are arranged in parallel on the translation control component 600. These parallel telescopic arms 700 together support the plate-shaped object 800, so that the contact area between the plate-shaped object 800 and the telescopic arms 700 is larger and the support is more solid.

[0054] In this embodiment, the plate-shaped object 800 includes, but is not limited to, photovoltaic panels, reflectors, and advertising screens.

[0055] It should be noted that the plate-shaped object 800 in this utility model is not limited to rigid plate-shaped materials; this utility model can also be used for soft materials such as curtains.

[0056] Example 2:

[0057] This embodiment provides another optional solution for the installation structure of plate-shaped objects, based on Embodiment 1.

[0058] In this embodiment, as Figure 4 and Figure 5 As shown, the telescopic arm unit 701 is provided with several support plates 711, and the plate-shaped object 800 is placed on the support plates 711. The support plates 711 can lift the plate-shaped object 800.

[0059] In this embodiment, as Figure 11 As shown, the support plate 711 has several small holes for fixing the plate-shaped object 800.

[0060] Example 3:

[0061] This embodiment provides another optional solution for the installation structure of plate-shaped objects, based on Embodiment 1 and Embodiment 2.

[0062] The difference between this utility model and Embodiments 1 and 2 is that, in this utility model, the plate-shaped object 800 can be disposed on the same side of the telescopic arm 700 (e.g., Figure 9 and Figure 10 As shown), this invention is not limited to unfolding and stacking multiple independent plate-shaped objects 800.

[0063] In this embodiment, the adjacent plate-shaped objects 800 are in an unfolded state and a stacked state with their ends close to each other, and the displacement difference is significant. Therefore, multiple plate-shaped objects 800 can be connected to form a whole by using a material with elastic deformation.

[0064] In this embodiment, the plate-shaped object 800 is mounted on the support frame 801, and an auxiliary frame is mounted on the telescopic arm 700. When the telescopic arm 700 extends, the auxiliary frame pushes the support frame 801 to unfold the plate-shaped object 800; when the telescopic arm 700 retracts, the auxiliary frame pulls back the support frame 801, thereby making the plate-shaped object 800 stacked.

[0065] In this embodiment, as Figures 8-14 As shown, the telescopic arm unit 701 is zigzag-shaped, and the turning parts of two intersecting telescopic arm units 701 are connected by a unit connecting shaft 703. Furthermore, the telescopic arm unit 701 has a sliding groove 7011, and both sides of the support frame 801 are provided with rotating pins 8011. One rotating pin is connected to the telescopic arm unit 701, and the other rotating pin 8011 is mounted on the auxiliary frame.

[0066] In this embodiment, the two ends of the rotating pin 801 are respectively located on two parallel telescopic arms 700, and the rotating pin 8011 is located in the sliding groove 7011 on the telescopic arm 700.

[0067] In this embodiment, the auxiliary frame includes a push-pull rod 704, a first connecting rod 7051, and a second connecting rod 7052. The first connecting rod 7051 and the second connecting rod 7052 are respectively hinged to two different telescopic arm units 701, and the middle parts of the two telescopic arm units 701 are connected by a unit connecting shaft 703. The first connecting rod 7051 and the second connecting rod 7052 are respectively located on both sides of the unit connecting shaft 703. The ends of the first connecting rod 7051 and the second connecting rod 7052 away from the unit connecting shaft 703 are hinged together by a push rod shaft 705.

[0068] In this embodiment, as Figure 12 and Figure 13 As shown, guide grooves 7031 are provided at both ends of the unit connecting shaft 703. One end of the push-pull rod 704 is placed in the guide groove 7031, and a coupling joint 7041 is provided at one end of the push-pull rod 704. The coupling joint 7041 has two shaft holes. The rotating pin 8011 on the other side of the support frame 801 is rotatably installed in the shaft holes of the coupling joint 7041. The other end of the push-pull rod 704 is hinged to the push rod shaft 705, and the guide groove 7031 is located between the coupling joint 7041 and the push rod shaft 705.

[0069] When the telescopic arm 700 extends, the two telescopic arm units 701 increase the angle between the first connecting rod 7051 and the second connecting rod 7052, thereby causing the push rod shaft 705 to push the connector 7041 of the push-pull rod 704 away from the guide groove 7031, pushing out one end of the plate-shaped object 800, thus unfolding the plate-shaped object 800. When the connector 7041 and the sliding grooves 7011 at both ends of the telescopic arm 700 are aligned, the multiple plate-shaped objects 800 on the telescopic arm 700 are fully unfolded (e.g., ...). Figure 9As shown). When the telescopic arm 700 retracts, the two telescopic arm units 701 cause the included angle between the first connecting rod 7051 and the second connecting rod 7052 to decrease, and the push-pull rod 704 causes one end of the support frame 801 to move closer to the middle of the telescopic arm unit 701, thereby causing the multiple plate-shaped objects 800 on the telescopic arm 700 to be stacked (as shown). Figure 8 (As shown).

[0070] Example 4:

[0071] This embodiment provides a balanced structure for the telescopic arm 700, based on any of the above embodiments.

[0072] In this embodiment, as Figures 15-17 As shown, a counterweight mounting plate 501 is arranged parallel to the outer side of the two long mounting plates of the mounting base 410. A transmission wheel 502 is provided at both ends of the counterweight mounting plate 501, and the two transmission wheels 502 on the counterweight mounting plate 501 are connected by a transmission chain 503.

[0073] There is a gap between the counterweight mounting plate 501 and the long mounting plate, and a lifting plate 504 is provided in the gap. A pulley 505 is provided at the top of the lifting plate 504, and the two ends of the pulley 505 are respectively located on the top surface of the counterweight mounting plate 501 and the long mounting plate. The bottom end of the lifting plate 504 is connected to the counterweight block 500, and a connecting rod 506 is provided on the lifting plate 504, which is connected to the transmission chain 502.

[0074] In this embodiment, the counterweight 500 is located at the end of the mounting base 410 away from the third drive motor 611. The lead screw nut 613 is connected to the part of the transmission chain 503 above the transmission wheel 502, and the part of the transmission chain 503 below the transmission wheel 502 is connected to the connecting rod 506. This makes the counterweight 500 and the lead screw nut 613 move in opposite directions, so that the counterweight 500 is aligned with the center of gravity of the telescopic arm 700.

[0075] In other embodiments, the drive wheel 502 may be driven by a separate servo motor. By interlocking the servo motor driving 502 with the third drive motor 611, the counterweight 500 and the lead screw nut 613 can also move in opposite directions.
