Description

Technical Field

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

[0002] With the increasingly severe global energy problems, solar energy, as a clean and renewable energy source, has gradually attracted wide attention and application. In recreational vehicle travel, solar panels, as an important way to supply power to recreational vehicles, can effectively utilize solar energy to provide power for recreational vehicles. However, the power generation efficiency of solar panels is greatly affected by the angle of sunlight irradiation. When the sun's rays are 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 recreational vehicle or when the angle of sunlight irradiation changes has become an urgent technical problem to be solved.

[0003] Most of the existing angle adjustment mechanisms for solar panels in recreational vehicles are fixed or can only perform single-axis angle adjustment. This makes it impossible for solar panels to always maintain the best illumination angle when facing sunlight at different angles, resulting in low light energy absorption efficiency. In addition, some multi-axis adjustment mechanisms are complex in structure and inconvenient to operate, making it difficult to achieve fast and accurate angle adjustment. Moreover, during the unfolding and storage processes of the panels, there is often a lack of automated design, increasing the operation burden on users. Summary of the Invention

[0004] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide an angle adjustment mechanism for a solar panel used in a recreational vehicle, which can achieve multi-angle adjustment of the solar panel through the combined use of a primary adjustment mechanism and a multi-axis adjustment mechanism, enabling it to always be perpendicular to the sun's rays, thereby improving the light energy absorption efficiency.

[0021] Further, a second motor is fixedly connected to the bottom of the connecting plate;

[0022] The linkage assembly includes a driving arm connected to the output end of the second motor. The two ends of the driving arm are respectively rotatably connected to driven rods, and the movable ends of the driven rods are rotatably connected to the bottom of the secondary plate.

[0030] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0031] The angle adjustment mechanism of the solar panel for a motorhome proposed by the present invention realizes multi-angle adjustment of the solar panel through the collaborative work of the primary adjustment mechanism and the multi-axis adjustment mechanism. This design can adjust the angle of the solar panel in real time according to the change of the sun's position, ensure that it is always perpendicular to the sun's rays, improve the light energy absorption efficiency of the photovoltaic panel, and overcome the problem of low light energy absorption efficiency caused by fixed angles or inflexible adjustment in the prior art. At the same time, the primary adjustment mechanism realizes a large-range adjustment of the overall angle of the solar panel through the cooperation of the first motor, the threaded rod, the push rod and the first cylinder, so that it can still maintain a good working state under different roof inclination angles, and improves the adaptability of the motorhome solar system.

[0032] In the design of the unfolding mechanism, the present invention can automatically complete the unfolding and retracting operations of the solar panel through components such as the second motor, the driving arm, and the driven rod, combined with the linkage unfolding structure of the auxiliary board and the main board, reducing the operation steps of the user and improving the convenience of use. The auxiliary board and the main board can maintain a stable trajectory movement under the guidance of the sliding rod and the drive of the linkage component, ensuring that the solar panel does not shift or shake during the unfolding process, thereby improving the stability of the system. The design of the unfolding mechanism also ensures the planar consistency of the main board and the auxiliary board after unfolding through the plugging and limiting structure, ensuring the maximum working area of the photovoltaic panel and improving the light energy absorption efficiency.

[0033] In the multi-axis adjustment mechanism adopted in the present invention, through the multi-directional adjustment of six second cylinders, precise angle control of the auxiliary plate and the main plate can be achieved. The combination of the multi-axis adjustment mechanism and the light sensor can detect the position change of the sun in real time, and adjust the tilt angle of the top plate by controlling the telescopic movement of the cylinder to ensure that the solar panel is always perpendicular to the sunlight. This design solves the problem of insufficient light energy absorption in the prior art due to the inability of the photovoltaic panel angle to change with the sun's position, and greatly improves the power generation efficiency of the solar panel. Through the automatic adjustment of the multi-axis adjustment mechanism, the present invention not only improves the automation level of the system, but also significantly reduces manual operation and enhances the intelligent level of the RV solar system.

[0062] In order to make the purpose and advantages of the present invention clearer, the present invention will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present invention, and does not strictly limit the specific protection scope claimed by the present invention.

[0063] Refer to Figure 1-11, An angle adjustment mechanism for a solar panel on a motorhome, including a primary adjustment mechanism 1 installed on the roof; a multi-axis adjustment mechanism 2 is provided at the inclined movable end of the primary adjustment mechanism 1. The multi-axis adjustment mechanism 2 can achieve multi-angle adjustment of the solar panel, ensuring that the panel can maintain the best illumination angle under sunlight at different angles, thereby maximizing light energy absorption; an unfolding mechanism 3 is provided at the movable end of the multi-axis adjustment mechanism 2. The unfolding mechanism 3 is used to unfold the solar panel during use and retract it when not in use to save space and reduce wind resistance, improving the stability and efficiency of the motorhome's driving; the primary adjustment mechanism 1 includes fixed rods 11 symmetrically fixed on the roof. The fixed rods 11 are installed on the roof through a pair of rotatably connected brackets. A turning plate 13 is provided between the fixed rods 11 on both sides. One end of the turning plate 13 is rotatably connected to the fixed rod 11, and a receiving chamber 131 is provided at the other end. The receiving chamber 131 is used to accommodate and protect the multi-axis adjustment mechanism 2; the other end of the fixed rod 11 is connected to a first motor 14 through a connecting shaft. The first motor 14 is responsible for driving the rotation of the threaded rod 15. The threaded rod 15 passes through the fixed rod 11 and is threadedly connected to the push rod 16. The push rod 16 can slide along the guide rod 111 under the drive of the threaded rod 15, thereby adjusting the angle of the turning plate 13; in addition, the turning plate 13 and the push rod 16 are connected by a first cylinder 17. The first cylinder 17 provides additional adjustment force and can provide more precise control and adjustment functions in the angle adjustment of the solar panel.

[0064] Refer to Figure 3 , A guide rod 111 is installed inside the fixed rod 11. 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, avoiding the deviation or shaking of the push rod 16; the push rod 16 and the guide rod 111 are in precise sliding fit, ensuring that the push rod 16 can move smoothly; a pin joint seat 161 is fixedly connected to the upper end surface of the middle part of the push rod 16. The pin joint seat 161 provides a fixed point for the push rod 16, further improving the stability of the push rod 16; a positioning rod 12 is also fixedly connected inside the fixed rod 11. One end of the positioning rod 12 is connected to 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, achieving precise adjustment between the push rod 16 and the fixed rod 11.

[0065] Refer to Figure 4, the shapes of the substrate 21 and the top plate 23 are both set as triangles. The triangular structure can provide stronger stability and balanced stress during use. There are six second cylinders 22 arranged between the substrate 21 and the top plate 23. The second cylinders 22 are distributed at each corner of the substrate 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 substrate 21 and the top plate 23 through a pin joint seat. At the upper end face of each corner of the substrate 21, a first pin joint seat 211 is fixedly connected, and at the lower end face of each corner of the top plate 23, a second pin joint seat 231 is arranged. The first pin joint seat 211 and the second pin joint seat 231 are connected to the second cylinder 22 through a hinged manner, ensuring the stability of the cylinder during operation and providing flexible multi-angle adjustment ability.

[0066] In a specific embodiment, the multi-axis adjustment mechanism 2 realizes precise control of the auxiliary plate 34 and the main plate 35 through six second cylinders 22 to ensure 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 substrate 21, the top plate 23, the second cylinder 22, and each execution component connected thereto.

[0067] First of all, the substrate 21 is fixed inside the accommodation bin 131 to ensure the stability and supporting effect of the entire multi-axis adjustment mechanism. The top plate 23 serves as the direct supporting structure for the auxiliary plate 34 and the main plate 35 and conducts multi-angle adjustment control through the six second cylinders 22 between it and the substrate 21. The quantity and distribution of the second cylinders 22 are crucial. Each second cylinder 22 is respectively connected to the corresponding pin joint seats on the substrate 21 and the top plate 23. A second pin joint seat 231 is arranged at each corner of the top plate 23 and is hinged to the other end of the second cylinder 22, enabling the top plate 23 to perform multi-degree-of-freedom movement adjustment.

[0068] During the multi-axis adjustment process, the second cylinders 22 respectively extend and contract their lengths to adjust the tilt angle of the top plate 23 by sensing the position change of the sun in real time. Since the six cylinders are evenly distributed at each corner of the top plate 23, they achieve multi-directional adjustment of the top plate 23 through precise cooperation. Specifically, when the angle of the sunlight changes, the control system will respectively adjust the extension and contraction lengths of the second cylinders 22 according to the detected light 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 tilt in multiple directions, ensuring that the auxiliary plate 34 and the main plate 35 mounted 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 correspondingly adjust the angle of the top plate 23 in the east-west direction. Some cylinders will shorten while others will elongate, causing the top plate 23 to tilt 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 panels maintain the optimal angle with respect to the sunlight.

[0070] In addition, the multi-axis adjustment mechanism 2 also incorporates light sensors to detect the sun's azimuth in real time. The signals are transmitted to the control module of the cylinders through a feedback system to precisely control the operation of the second cylinder 22. Through this precise multi-axis adjustment mechanism, the auxiliary plate 34 and the main plate 35 can always maintain a perpendicular state to the sunlight, ensuring maximum light energy absorption regardless of the sun's azimuth and improving the working efficiency of the solar panels.

[0071] Refer to Figure 5 , the deployment mechanism 3 includes a connecting plate 31 connected to the top plate 23. The connecting plate 31 is fastened to the surface of the top plate 23 by screws to ensure that the deployment mechanism 3 does not shake during deployment and retraction; a sliding rod 32 and a linkage assembly 33 are installed on the upper end surface of the connecting plate 31. The sliding rods 32 are symmetrically distributed on both sides of the connecting plate 31 to guide the parallel movement trajectory of the auxiliary plate 34 and ensure that the auxiliary plate 34 can remain stable during deployment and retraction; the linkage assembly 33 is installed in the middle part of the sliding rod 32 to drive the deployment and retraction of the auxiliary plate 34 and the main plate 35; the auxiliary plate 34 and the main plate 35 are connected to the linkage assembly 33 and are used for light energy collection. When the panels are deployed, the auxiliary plate 34 and the main plate 35 work together to maximize the solar absorption area;

[0072] When it is necessary to deploy the solar panels, the second motor 311 starts and begins to operate. The second motor 311 is connected to the driving arm 332 through the output shaft. As the second motor 311 rotates, the driving arm 332 starts to rotate clockwise. Both ends of the driving arm 332 are respectively connected to the driven rods 333 by hinge means, and one end of the driven rod 333 is fixed to the bottom of the auxiliary plate 34. The clockwise rotation of the driving arm 332 drives the driven rod 333 to move synchronously, causing the auxiliary plate 34 to deploy smoothly outwards. At the same time, the sliding rod 32 limits the movement trajectory of the auxiliary plate 34 to ensure that the auxiliary plate 34 moves in a straight line during deployment and avoids tilting or misalignment.

[0073] As the auxiliary board 34 is gradually unfolded, the sliding rod 32 connected to the bottom of the auxiliary board 34 starts to slide. The sliding rod 32 consists of two spliced rods 321, which are in sliding connection with each other. One end of the spliced rod is fixed with a stop head 322, which ensures that the auxiliary board 34 will not exceed the set unfolding angle during the unfolding process. When the auxiliary board 34 is fully unfolded, the stop head 322 is fixed at the end of the slide rail, restricting the further movement of the auxiliary board 34. At the same time, the planes of the auxiliary board 34 and the main board 35 are kept consistent.

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

[0075] When the main board 35 and the auxiliary board 34 are fully unfolded and on the same horizontal plane, the photovoltaic collection area of the entire solar panel reaches the maximum, enabling full utilization of solar energy resources and improving the light energy absorption efficiency. At the same time, the linkage design of each component during the unfolding process ensures the smooth unfolding of the auxiliary board 34 and the main board 35. Even in complex environments or when the vehicle body shakes, precise unfolding operations can still be achieved.

[0076] Refer to Figure 5-6 , a second motor 311 is fixedly installed at the bottom of the connecting plate 31. The second motor 311 is responsible for driving the operation of the linkage component 33; the linkage component 33 includes a driving arm 332 connected to the output end of the second motor 311. Both ends of the driving arm 332 are rotatably connected with driven rods 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 auxiliary board 34, ensuring that the auxiliary board 34 can be unfolded or retracted as the driving arm 332 rotates.

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

[0078] Refer to Figure 9-11, symmetrically and fixedly connected to the lower end face of the main board 35 are connecting columns 351, which are used to cooperate with the positioning tubes 3321 on the driving arms 332 to ensure that the main board 35 can move synchronously with the driving arms 332 during the unfolding process; the positioning tubes 3321 are installed on the upper end face of the driving arms 332 and are used for inserting into the connecting columns 351 to ensure the precise alignment of the main board 35 during unfolding and folding; through this structural design, the main board 35 and the auxiliary board 34 can maintain good synchronism during unfolding and folding, thereby realizing automatic control.

[0079] Refer to Figure 9-11 , fixedly connected to the upper end face of the positioning disk 331 are two positioning rings 3311, which are used to provide the limiting function for the main board 35 and the auxiliary board 34. A clamping groove 3312 is formed on the positioning ring 3311, and the cross-section of the clamping groove 3312 is a V-shaped structure to ensure that the main board 35 can be firmly clamped into a predetermined position during rotation; an elastic telescopic tube 352 is also provided on the lower end face of the main board 35, which can provide additional resilience when the main board 35 rotates to ensure its stability when it is clamped into the clamping groove 3312 of the positioning ring 3311.

[0080] Refer to Figure 7 , symmetrically installed on the upper end face of the connecting plate 31 are sliding rods 32. The sliding rods 32 include two spliced rods 321. One end of the spliced rod 321 is fixedly connected with a stop head 322, which can limit the sliding range of the spliced rod 321 to ensure that the auxiliary board 34 moves smoothly along a set track during unfolding and folding; a positioning column 3221 connected to the bottom of the auxiliary board 34 is provided on the top of the stop head 322, which is used to firmly install the auxiliary board 34 on the spliced rod 321; a through hole 3222 is also formed at the bottom of the stop head 322 for adjusting and installing the spliced rod 321.

[0081] Refer to Figure 6-7 , also provided on the upper end face of the connecting plate 31 is a cushion block 312 connected to the sliding rod 32, which is used to improve the stability of the sliding rod 32 and ensure the smooth operation of the sliding rod 32 during the process of unfolding and folding the auxiliary board 34.

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

[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 through the push rod 16, and the threaded rod 15 and the push rod 16 are in threaded connection. During the rotation of the threaded rod 15, it will drive the push rod 16 to slide along the guide rod 111. As the push rod 16 slides and is pushed by the first cylinder 17, the included angle between the turning plate 13 and the fixed rod 11 will gradually increase;

[0084] When the elevation angle of the turning plate 13 reaches a predetermined value, it is necessary to deploy the auxiliary plate 34 and the main plate 35 at this time. The deployment process is as follows: The second motor 311 drives the driving arm 332 to rotate clockwise. As the driving arm 332 rotates clockwise, it will drive the driven rod 333 to move synchronously. During the movement of the driven rod 333, the two auxiliary plates 34 will be pushed towards both ends of the main plate 35. And during the pushing process of the auxiliary plate 34, the slide rod 32 connected to the bottom of the auxiliary plate 34 can limit the movement trajectory of the two auxiliary plates 34, so that the movement trajectory of the auxiliary plate 34 is a straight line;

[0085] During the rotation of the driving arm 332, it also drives the main plate 35 inserted on the driving arm 332 to rotate synchronously. During the rotation of the main plate 35, when the elastic telescopic tube 352 is caught in the positioning groove 3312, the main plate 35 and the auxiliary plate 34 will be on the same horizontal plane;

[0086] When it is necessary to retract the auxiliary plate 34 and the main plate 35, only need to let the second motor 311 drive the driving arm 332 to rotate counterclockwise;

[0087] During the process of collecting solar energy, when the position of the sun changes, the multi-axis adjustment mechanism 2 can make the auxiliary plate 34 and the main plate 35 always perpendicular to the sun's rays;

[0088] When the multi-axis adjustment mechanism 2 is operating, by controlling the telescopic lengths of the six top plates 23, the angles of the top plates 23 can be adjusted at multiple angles. When the angles of the top plates 23 change, the angles of the auxiliary 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 the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and retouches can be made, and these improvements and retouches should also be regarded as the protection scope of the present invention. The structures, devices, and operation methods not specifically described and explained in the present invention are implemented according to the conventional means in the art without special explanation and limitation.
