[0002] Solar photovoltaic (PV) power generation systems are a new type of power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. With the deterioration of the environment and the deepening of human environmental awareness, PV power generation, as one of the main green energy sources, is being used more and more.

[0003] Vehicle-mounted solar photovoltaic panels are solar power generation devices integrated into the roof or surface of a car. They convert sunlight into direct current through semiconductor materials to provide auxiliary power to the vehicle. They are mainly used in new energy vehicles, RVs, and other scenarios to achieve energy replenishment and electrical power supply.

[0004] Because a single solar photovoltaic panel is limited by its area, the amount of electricity it converts is generally low. Multiple solar photovoltaic panels need to be connected in series and parallel to form a solar photovoltaic array to achieve a certain amount of electricity. However, due to the limited area on the roof of a small car, a large area of ​​photovoltaic panels cannot be installed. Therefore, some solar photovoltaic panels need to be stacked. When the car is parked and generating electricity, the photovoltaic panels are displayed. When the car is moved or stored, the photovoltaic panels are retracted. Currently, the display and retraction of photovoltaic panels are usually achieved by motor drive, which results in high costs and difficult maintenance.

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1

[0034] This embodiment discloses a manual locking mechanism and a vehicle-mounted solar photovoltaic panel, referencing... Figures 1-6 As shown, it mainly includes a locking assembly 1, a positioning post 2, a first component 3 and a second component 4, wherein the locking assembly 1 is fixedly installed on the lower end of the first component 3 by a fastener 11, and the positioning post 2 is fixedly installed on the second component 4.

[0035] Reference Figure 1 and Figure 2 As shown, the vehicle-mounted solar photovoltaic panel in this embodiment has an overall structure with two overlapping layers. The first component 3 is the lower solar photovoltaic panel, and the second component 4 is the lower support on the outer periphery of the lower solar photovoltaic panel. Slide rails 31 are fixedly installed on both sides of the first component 3, and slide rails 41 are fixedly installed on the inner periphery of the second component 4 relative to the slide rails 31. Through the cooperation between the slide rails 31 and the slide rails 41, the first component 3 can slide relative to the second component 4 for adjustment. An upper support 6 is fixedly installed on the upper end of the lower support, and the upper solar photovoltaic panel 5 is fixedly installed on the upper support 6, realizing the overlapping arrangement of the vehicle-mounted solar photovoltaic panels. The lower solar photovoltaic panel can slide outward relative to the upper solar photovoltaic panel 5 to display the photovoltaic panel. When moving or storing, the lower photovoltaic panel can be retracted and locked by a manual locking mechanism. The overall structure is compact and easy to operate.

[0036] Reference Figure 3 and Figure 6As shown, the locking assembly 1 mainly includes a fixing member 11, a latch 12, an unlocking member 13, a pull rod 14, and a rotation adjustment assembly 16. The fixing member 11 is fixedly installed at the lower end of the first component 3, and a connecting shaft 111 and a connecting shaft 112 are integrally connected inside the fixing member 11. The latch 12 has a first end 121 and a second end 122. A through connecting hole 124 is provided between the first end 121 and the second end 122 of the latch 12. A horizontally arranged limiting groove 123 is provided at the first end of the latch 12, and a notch 125 is provided at the second end 122 of the latch 12. The latch 12 is rotatably connected to the connecting shaft 111 through the connecting hole 124 and has a first position and a second position during rotation. The unlocking member 13 has a connecting hole 132, one end of which is integrally connected to a protrusion 131, and the other end is rotatably connected to the pull rod 14. The unlocking member 13 is rotatably connected to the connecting shaft 111 through the connecting hole 132. 2. This allows the protrusion 131 on the unlocking component 13 to be inserted into the notch 125 on the latch 12 for abutment and limiting. A rotation adjustment component 16 is fixedly installed at the other end of the fixing component 11. The rotation adjustment component 16 can rotate relative to the fixing component 11. The rotation adjustment component 16 is connected to the other end of the pull rod 14 through the connecting piece 15, realizing the movable connection between the unlocking component 14, the pull rod 14, and the rotation adjustment component 16. Rubber rings 17 are installed between the pull rod 14, the unlocking component 13, and the connecting piece 15. The rubber rings 17 can provide a certain amount of deformation to effectively alleviate the torsion problem generated between the pull rod 14, the unlocking component 13, and the connecting piece 15 during rotation. By axially adjusting the rotation adjustment component 16, the unlocking component 13 is controlled to rotate relative to the connecting shaft 112, so that the protrusion 131 at the end of the unlocking component 13 can disengage from the notch 125 on the latch 12, thereby unlocking. The whole operation process is simple and convenient.

[0037] Reference Figure 4As shown, when the latch 12 is in the first position, the positioning post 2 on the second component 4 is inserted into the limiting groove 123 on the latch 12 to form a snap-fit. At this time, the lower solar photovoltaic panel is in a retracted and locked state. A groove 126 is provided on the outer periphery of the latch 12 at the connecting hole 124. A V-spring 127 is sleeved on the connecting shaft 111, so that the V-spring 127 is inserted into the groove 126 on the latch 12. One end of the V-spring 127 is fixedly abutted against the inner wall of the groove 126 to form a limiting installation, so that the other end of the V-spring 127 elastically abuts against the inner wall of the fixing member 11. Under the elastic abutment state of the V-spring 127, the latch 12 has a tendency to rotate clockwise around the connecting shaft 111. Similarly, a groove 133 is provided on the outer periphery of the unlocking member 13 at the connecting hole 132. A V-spring 134 is sleeved on the connecting shaft 112, so that the V-spring 134... The second groove 1133 is embedded in the unlocking member 13. One end of the second V-shaped spring 134 is fixedly abutted against the inner wall of the second groove 133 to form a limiting installation, so that the other end of the second V-shaped spring 134 elastically abuts against the inner wall of the fixing member 11. Under the elastic abutment state of the second V-shaped spring 134, the unlocking member 13 has a tendency to rotate counterclockwise around the second connecting shaft 112. The protrusion 131 integrally connected to the end of the unlocking member 13 is embedded in the notch 125 opened at the second end 122 of the latch 12 to form an abutment limit. Since the latch 12 and the unlocking member 13 rotate in opposite directions under the elastic drive of the first V-shaped spring 127 and the second V-shaped spring 134 respectively, the protrusion 131 on the unlocking member 13 is tightly locked into the notch 125 on the latch 12, forming a locking state between the two, which can stably lock the first component 3 to the second component 4, that is, the lower solar photovoltaic panel is locked to the lower support.

[0038] Reference Figure 5As shown, when the lower solar photovoltaic panel needs to be opened, from the first position, the rotary adjustment component 16 is rotated by hand. This pulls the lever 14 away from the latch 12 via the connecting piece 17. Since one end of the unlocking piece 13 is rotatably connected to the lever 14, under the pull of the lever 14, the unlocking piece 13 rotates clockwise around the connecting shaft 112. The protrusion 131 on the unlocking piece 13 disengages from the notch 125 on the latch 12. Because the latch 12 loses the pressure of the protrusion 131 on the unlocking piece 13, under the elastic drive of the V-spring 127 on the latch 12, the latch 12... The first component 3 rotates clockwise around the connecting shaft 111, allowing the positioning pin 2 to disengage from the limiting groove 123 and achieve the unlocked state. At this time, the first component 3 can slide relative to the second component 4. When the rotation adjustment component 16 is released by hand, the second V-shaped spring 134 elastically recovers under the elastic drive of the second V-shaped spring 134, driving the unlocking component 13 to rotate counterclockwise. This causes the protrusion 131 at the end of the unlocking component 13 to abut against the second end 122 of the latch 12 to form a limit. At this time, the opening of the limiting groove 123 on the latch 12 faces outward and remains stationary, which is the second position of the latch 12.

[0039] When the lower solar photovoltaic panel needs to be retracted, the first component 3 is slowly pushed by hand so that the positioning post 2 is embedded in the limiting groove 123 on the latch 12. As the first component 3 slides inward, the positioning post 2 can press against the inner circumference of the limiting groove 123 and drive the latch 12 to rotate counterclockwise until the end of the latch 12 abuts against the limiting block 128 installed inside the fixing component 11. At this time, the protrusion 131 at the end of the unlocking component 13 is embedded in the notch 125 on the latch 12. The first component 3 and the second component 4 form a locking state. The overall structure is compact, the manual operation is convenient, the cost is saved, and the maintenance is easy.

[0040] Example 2

[0041] This embodiment discloses a manual locking mechanism and a solar photovoltaic panel, based on Embodiment 1, and further referring to... Figure 7-10 Please provide an explanation.

[0042] In this second embodiment, the locking component 1 in the first embodiment is partially modified. The second end 122 of the latch 12 is set as an outwardly protruding arc surface. A sleeve 8 is fixedly installed inside the fixing member 11. A positioning pin 7 is installed through the center of the sleeve 8. One end of the positioning pin 7 can abut against the second end 122 of the latch 12, and the other end abuts against the fixing member 11 through a fixedly connected spring 9. An unlocking lever 10 is fixedly installed near the connection end of the positioning pin 7 and close to the spring 9. The unlocking lever 10 extends out of the fixing member 11 through the through hole 113 on the fixing member 11.

[0043] Reference Figure 9As shown, when the latch 12 is in the first position, the positioning pin 2 is embedded in the limiting groove 123 on the latch 12. Due to the pressure of the spring 9, the end of the positioning pin 7 away from the spring 9 abuts against the second end 122 of the latch 12. Under the elastic drive of the V-spring 125, the latch 12 tends to rotate clockwise around the connecting shaft 111, so that the latch 12 is tightly abutted against the positioning pin 7, forming a locked state.

[0044] Reference Figure 10 As shown, when the lower solar photovoltaic panel needs to be opened, based on the first position, push the unlocking lever 10 by hand to move it away from the latch 12, so that the positioning pin 7 moves away from the latch 12 along the inner circumference of the sleeve 8. When the latch 12 loses the contact of the positioning pin 7, the latch 12 rotates clockwise around the connecting shaft 111 under the driving action of the V-spring 125. It stops rotating when the positioning pin 2 can disengage from the limiting groove 123. When the unlocking lever 10 is released, the spring 9 resets and pushes the positioning pin 7 to move away from the spring 9, so that the end of the positioning pin 7 abuts against the arc surface of the second end 122 of the latch 12 and is limited, forming the second position of the latch 12.

[0045] When the lower solar photovoltaic panel needs to be retracted, the first component 3 is slowly pushed by hand so that the positioning post 2 is embedded in the limiting groove 123 on the latch 12. As the first component 3 slides inward, the positioning post 2 can press against the inner circumference of the limiting groove 123 and drive the latch 12 to rotate counterclockwise. The arc-shaped surface of the second end 122 of the latch 12 slides and abuts against the positioning pin 7 until it is fully limited. The first component 3 and the second component 4 form a locking state. The overall structure is compact, the manual operation is convenient, the cost is saved, and the maintenance is easy.

[0046] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected by this utility model. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
