Description

Technical Field

[0001] The invention belongs to the technical field of solar panels, and in particular relates to an angle adjustment mechanism for a solar panel for a recreational vehicle. Background Art

[0002] As global energy problems become increasingly severe, solar energy, as a clean and renewable energy source, has gradually attracted widespread attention and application. In RV travel, solar panels, as an important way to power RVs, can effectively use solar energy to provide electricity for RVs. However, the power generation efficiency of solar panels is greatly affected by the angle of sunlight. When the sunlight is perpendicular to the surface of the panel, the light energy absorption efficiency is the highest. Therefore, in order to improve the power generation efficiency of solar panels, how to adjust the angle of solar panels in real time during the movement of the RV or when the angle of sunlight changes has become a technical problem that needs to be solved urgently.

[0003] Most of the existing RV solar panels have fixed angle adjustment mechanisms or can only adjust the angle of a single axis, which means that the solar panels cannot always maintain the best lighting angle when facing sunlight at different angles, resulting in low light energy absorption efficiency. In addition, some multi-axis adjustment mechanisms have complex structures and inconvenient operations, making it difficult to achieve fast and accurate angle adjustment. In addition, there is often a lack of automated design during the unfolding and storage of the panels, which increases the user's operating burden. Summary of the invention

[0031] The angle adjustment mechanism of the solar panel for RV proposed in the present invention realizes multi-angle adjustment of the solar panel through the coordinated work of the primary adjustment mechanism and the multi-axis adjustment mechanism. The design can adjust the angle of the solar panel in real time according to the change of the sun's position to ensure that it always remains perpendicular to the sunlight, thereby improving the light energy absorption efficiency of the photovoltaic panel and overcoming the problem of low light energy absorption efficiency caused by fixed angles or inflexible adjustment in the prior art.

It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention.

A flip plate 13 is arranged between the fixed rods 11, one end of the flip plate 13 is rotatably connected to the fixed rod 11, and a accommodating chamber 131 is arranged at the other end thereof, and the accommodating chamber 131 is used to store and protect the multi-axis adjustment mechanism 2; the other end of the fixed rod 11 is connected to the first motor 14 through a connecting shaft, and the first motor 14 is responsible for driving the threaded rod 15 to rotate, and the threaded rod 15 passes through the fixed rod 11 and is threadedly connected to the push rod 16, and the push rod 16 can slide along the guide rod 111 under the drive of the threaded rod 15, so as to adjust the angle of the flip plate 13; in addition, the flip plate 13 is connected to the push rod 16 through the first cylinder 17, and the first cylinder 17 provides additional adjustment force, which can provide more precise control and adjustment functions in the angle adjustment of the solar panel.

[0064] See also Figure 3 A guide rod 111 is installed on the inner side of the fixed rod 11, and one end of the push rod 16 is sleeved on the guide rod 111 and can slide along the guide rod 111. The guide rod 111 ensures that the push rod 16 can maintain a smooth movement trajectory during the angle adjustment process to avoid the push rod 16 from deflecting or shaking; the push rod 16 and the guide rod 111 are precisely matched with each other in a sliding manner to ensure that the push rod 16 can move smoothly; the middle upper end surface of the push rod 16 is fixedly connected with a pin seat 161, and the pin seat 161 provides a fixing point for the push rod 16, further improving the stability of the push rod 16; the inner side of the fixed rod 11 is also fixedly connected with a positioning rod 12, and the positioning rod 12 is connected to one end of the threaded rod 15 through a rotating shaft. The rotation of the threaded rod 15 drives the push rod 16 along the guide rod 111, thereby realizing precise adjustment between the push rod 16 and the fixed rod 11.

[0065] See also Figure 4The shapes of the base plate 21 and the top plate 23 are both set to be triangular, and the triangular structure can provide stronger stability and force balance during use; six second cylinders 22 are arranged between the base plate 21 and the top plate 23, and the second cylinders 22 are distributed in various corners of the base plate 21 and the top plate 23, and are used to adjust the angle of the top plate 23. Each end of the second cylinder 22 is respectively connected to the base plate 21 and the top plate 23 through a pin seat; the upper end surface of each corner of the base plate 21 is fixedly connected with a first pin seat 211, and the lower end surface of each corner of the top plate 23 is provided with a second pin seat 231, and the first pin seat 211 and the second pin seat 231 are connected to the second cylinder 22 by a hinged manner, which ensures the stability of the cylinder during work and provides flexible multi-angle adjustment capability.

[0066] In a specific embodiment, the multi-axis adjustment mechanism 2 uses six second cylinders 22 to achieve precise control of the sub-plate 34 and the main plate 35, ensuring that they are always perpendicular to the sunlight to maximize the light energy absorption efficiency. The core components of the multi-axis adjustment mechanism 2 are the base plate 21, the top plate 23, the second cylinders 22, and various actuators connected thereto.

[0067] First, the base plate 21 is fixed inside the storage chamber 131 to ensure the stability and support of the entire multi-axis adjustment mechanism. The top plate 23 serves as a direct support structure for the sub-plate 34 and the main plate 35, and is adjusted and controlled at multiple angles through the six second cylinders 22 between the base plate 21. The number and distribution of the second cylinders 22 are crucial. Each second cylinder 22 is connected to the corresponding pin joints of the base plate 21 and the top plate 23. Each corner of the top plate 23 is provided with a second pin joint 231, which is hinged to the other end of the second cylinder 22, so that the top plate 23 can be adjusted in multiple degrees of freedom.

[0068] During the multi-axis adjustment process, the second cylinder 22 senses the position change of the sun in real time and adjusts the tilt angle of the top plate 23 by extending and retracting its length. Since the six cylinders are evenly distributed in each corner of the top plate 23, they can achieve multi-directional adjustment of the top plate 23 through precise coordination. Specifically, when the angle of sunlight changes, the control system will adjust the extension length of the second cylinder 22 according to the detected illumination angle to change the tilt angle of the top plate 23. In this way, through the coordinated action of the six cylinders, the top plate 23 can be tilted in multiple directions, thereby ensuring that the sub-plate 34 and the main plate 35 installed thereon are always perpendicular to the sunlight.

[0069] For example, when the sun moves from east to west, the cylinders in the multi-axis adjustment mechanism 2 will adjust the east-west angle of the top plate 23 accordingly. Some cylinders will shorten, while others will lengthen, so that the top plate 23 is tilted in the east-west direction. Similarly, when the sun gradually rises or sets from the horizon, the cylinders will also adjust the north-south tilt angle of the top plate 23 to ensure that the solar panel maintains the best angle with the sunlight.

[0070] In addition, the multi-axis adjustment mechanism 2 also detects the position of the sun in real time in combination with a light sensor, transmits a signal to the control module of the cylinder through a feedback system, and accurately controls the action of the second cylinder 22. Through this precise multi-axis adjustment mechanism, the auxiliary panel 34 and the main panel 35 can always maintain a state of being perpendicular to the sunlight, and no matter what position the sun is in, it can ensure the maximum degree of light energy absorption, thereby improving the working efficiency of the solar panel.

[0071] See also Figure 5 The unfolding mechanism 3 includes a connecting plate 31 connected to the top plate 23, and the connecting plate 31 is fastened to the surface of the top plate 23 by screws to ensure that the unfolding mechanism 3 does not shake when unfolding and retracting; a sliding rod 32 and a linkage assembly 33 are installed on the upper end surface of the connecting plate 31, and the sliding rods 32 are symmetrically distributed on both sides of the connecting plate 31, and are used to guide the parallel movement trajectory of the sub-plate 34 to ensure that the sub-plate 34 can remain stable when unfolding and retracting; the linkage assembly 33 is installed in the middle part of the sliding rod 32, and is used to drive the unfolding and retracting of the sub-plate 34 and the main board 35; the linkage assembly 33 is connected to the sub-plate 34 and the main board 35, and the sub-plate 34 and the main board 35 are used for collecting light energy. When the solar panel is unfolded, the sub-plate 34 and the main board 35 work together to maximize the solar energy absorption area;

[0072] When the solar panel needs to be unfolded, the second motor 311 starts and starts working, and the second motor 311 is connected to the driving arm 332 through the output shaft. As the second motor 311 runs, the driving arm 332 starts to rotate clockwise. The two ends of the driving arm 332 are respectively connected to the driven rod 333 by a hinged manner, and one end of the driven rod 333 is fixed to the bottom of the sub-panel 34. The clockwise rotation of the driving arm 332 drives the driven rod 333 to move synchronously, so that the sub-panel 34 is smoothly unfolded outward. At the same time, the sliding rod 32 limits the movement trajectory of the sub-panel 34 to ensure that the sub-panel 34 maintains a straight line motion during the unfolding process to avoid tilting or misalignment.

[0073] As the secondary plate 34 is gradually unfolded, the slide bar 32 connected to the bottom of the secondary plate 34 begins to slide. The slide bar 32 is composed of two splicing rods 321, which are connected and matched by sliding. A stopper 322 is fixed at one end of the splicing rod, and the stopper 322 ensures that the secondary plate 34 does not exceed the set unfolding angle during the unfolding process. When the secondary plate 34 is fully unfolded, the stopper 322 is fixed to the end of the slide rail, limiting the further movement of the secondary plate 34, while the planes of the secondary plate 34 and the main plate 35 remain consistent.

[0074] When the auxiliary panel 34 is unfolded, the rotation of the driving arm 332 also drives the main panel 35 to unfold. The main panel 35 is inserted into the positioning tube 3321 of the driving arm 332 through the positioning column 351. As the driving arm 332 rotates, the main panel 35 rotates synchronously. When the main panel 35 rotates to a predetermined position, the elastic telescopic tube 352 on the main panel 35 is aligned with the V-shaped positioning groove 3312 on the positioning plate 331, and the elastic telescopic tube 352 is automatically inserted into the positioning groove 3312, ensuring that the main panel 35 is fixed on the same horizontal plane as the auxiliary panel 34 after unfolding, thereby forming a complete photovoltaic surface.

[0075] When the main panel 35 and the auxiliary panel 34 are fully unfolded and on the same horizontal plane, the photovoltaic collection area of ​​the entire solar panel is maximized, and solar energy resources can be fully utilized to improve the efficiency of light energy absorption. At the same time, the linkage design of each component during the unfolding process ensures the smooth unfolding of the auxiliary panel 34 and the main panel 35, and accurate unfolding operation can still be achieved regardless of the complex environment or when the vehicle body is shaking.

[0076] See also Figure 5-6 A second motor 311 is fixedly installed at the bottom of the connecting plate 31, and the second motor 311 is responsible for driving the linkage assembly 33; the linkage assembly 33 includes a driving arm 332 connected to the output end of the second motor 311, and both ends of the driving arm 332 are rotatably connected to a driven rod 333, one end of the driven rod 333 is connected to the driving arm 332 through a rotating shaft, and the other end is connected to the bottom of the sub-plate 34 to ensure that the sub-plate 34 can be expanded or retracted with the rotation of the driving arm 332.

[0077] See also Figure 8 The driving arm 332 is also rotatably connected to a positioning plate 331, which is installed at the upper end of the driving arm 332 and fixedly connected to the connecting plate 31 through a rotating shaft. The positioning plate 331 is used to control the rotation direction and position of the main board 35; the positioning plate 331 and the main board 35 work in coordination through rotation to ensure that the main board 35 and the sub-board 34 can be accurately aligned during operation to form a consistent light collection plane.

[0078] See also Figure 9-11The lower end surface of the main board 35 is symmetrically fixedly connected with a connecting column 351, and the connecting column 351 is used to cooperate with the positioning tube 3321 on the driving arm 332 to ensure that the main board 35 can move synchronously with the driving arm 332 during the unfolding process; the positioning tube 3321 is installed on the upper end surface of the driving arm 332, and is used to be plugged with the connecting column 351 to ensure the precise alignment of the main board 35 when unfolding and folding; through this structural design, the main board 35 and the sub-board 34 can maintain good synchronization when unfolding and folding, thereby realizing automatic control.

[0079] See also Figure 9-11 Two positioning rings 3311 are fixedly connected to the upper end surface of the positioning plate 331. The positioning rings 3311 are used to provide a limiting function for the main board 35 and the sub-board 34. A locking groove 3312 is provided on the positioning ring 3311. The cross-section of the locking groove 3312 is a V-shaped structure, which ensures that the main board 35 can be firmly inserted into the predetermined position when rotating; the lower end surface of the main board 35 is also provided with an elastic telescopic tube 352, which can provide additional resilience when the main board 35 rotates, ensuring that it remains stable when it is inserted into the locking groove 3312 of the positioning ring 3311.

[0080] See also Figure 7 A sliding rod 32 is symmetrically installed on the upper end surface of the connecting plate 31, and the sliding rod 32 includes two splicing rods 321 spliced ​​to each other. One end of the splicing rod 321 is fixedly connected to a stopper 322, and the stopper 322 can limit the sliding range of the splicing rod 321 to ensure that the sub-plate 34 moves smoothly along the set trajectory when unfolding and folding; a positioning column 3221 connected to the bottom of the sub-plate 34 is provided on the top of the stopper 322, and the positioning column 3221 is used to firmly install the sub-plate 34 on the splicing rod 321; a through hole 3222 is also provided at the bottom of the stopper 322 for adjusting and installing the splicing rod 321.

[0081] See also Figure 6-7 The upper end surface of the connecting plate 31 is also provided with a pad 312 connected to the slide rod 32. The pad 312 is used to improve the stability of the slide rod 32 and ensure the smooth operation of the slide rod 32 during the process of unfolding and folding the sub-plate 34.

[0082] The working principle of the present invention is:

[0083] When the primary adjustment mechanism 1 performs angle adjustment, the first motor 14 drives the threaded rod 15 installed on its output end to rotate, the threaded rod 15 penetrates the push rod 16, and the threaded rod 15 and the push rod 16 are threadedly connected. The threaded rod 15 drives the push rod 16 to slide along the guide rod 111 during the rotation activity. As the push rod 16 slides and under the push of the first cylinder 17, the angle between the flip plate 13 and the fixed rod 11 gradually increases;

[0084] When the elevation angle of the flip plate 13 reaches a predetermined value, the auxiliary plate 34 and the main plate 35 need to be unfolded, and the unfolding process is as follows: the second motor 311 drives the driving arm 332 to rotate clockwise, and as the driving arm 332 rotates clockwise, the driven rod 333 is driven to move synchronously, and the driven rod 333 moves during the movement of the two auxiliary plates 34 toward the two ends of the main plate 35, and during the pushing process of the auxiliary plates 34, the sliding rod 32 connected to the bottom of the auxiliary plates 34 can limit the moving trajectory of the two auxiliary plates 34, so that the moving trajectory of the auxiliary plates 34 can be straight.

[0085] During the rotation of the driving arm 332, the main board 35 plugged on the driving arm 332 is also driven to rotate synchronously. During the rotation of the main board 35, when the elastic expansion tube 352 is inserted into the clamping groove 3312, the main board 35 and the auxiliary board 34 will be on the same horizontal plane.

[0086] When the auxiliary plate 34 and the main plate 35 need to be folded up, the second motor 311 only needs to drive the driving arm 332 to rotate counterclockwise;

[0087] In the process of collecting solar energy, when the position of the sun changes, the multi-axis adjustment mechanism 2 can make the auxiliary panel 34 and the main panel 35 always perpendicular to the sunlight;

[0088] When the multi-axis adjustment mechanism 2 is in operation, by controlling the telescopic length of the six top plates 23, the angle of the top plate 23 can be adjusted at multiple angles. When the angle of the top plate 23 changes, the angles of the sub-plate 34 and the main plate 35 can be adjusted at multiple angles so that they can always be perpendicular to the sunlight.

[0089] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
