Description

Technical Field

[0001] This utility model relates to the field of photovoltaic equipment technology, and in particular to a locking mechanism, and also to a vehicle-mounted solar photovoltaic panel having the locking mechanism. Background Technology

[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, the roof of a small car has limited area and cannot accommodate a large area of ​​photovoltaic panels. 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 and locked. Currently, the display and retrieval of photovoltaic panels are usually achieved by motor drive, which results in high costs and difficult maintenance.

[0005] Therefore, this utility model provides a new technical solution to solve the above problems. Utility Model Content

Detailed Implementation

[0026] 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.

[0027] This embodiment discloses a locking mechanism and a vehicle-mounted solar photovoltaic panel, referencing... Figures 1 to 7 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.

[0028] Reference Figure 1 and Figure 2As 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 solar photovoltaic panel can be retracted and locked by a locking mechanism. The overall structure is compact and easy to operate.

[0029] Reference Figure 3 As shown, the locking assembly 1 mainly includes a fixing member 11, a latch 12, a pull rod 13, and a tension spring 14. The fixing member 11 is fixedly installed on the first component 3, and a connecting shaft 113 is 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. The latch 12 is rotatably connected to the connecting shaft 113 through the connecting hole 124 and has a first position and a second position during rotation. A limiting groove 123 is provided at the first end 121 of the latch 12 facing the positioning post 2. The second end 122 of the latch 12 is connected to the fixing member 11 through the tension spring 14. A connecting part 125 is provided at the second end of the latch 12. The pull rod 13 is arranged opposite to the tension spring 14. One end of the pull rod 13 is hinged to the connecting part 125, and the other end passes through the through hole 111 opened on the side of the fixing member 11 and extends to the outside of the fixing member 11.

[0030] Reference Figure 4 and Figure 5 As shown, when the latch 12 is in the first position, the positioning post 2 on the second component 4 can be inserted into the limiting groove 123 at the first end 121 of the latch 12, and the two form a snap-fit ​​limiting. Since the latch 12 is fixedly connected to the fixing member 11 by the tension spring 14 at the second end position, under the elastic traction of the tension spring 14, the latch 12 tends to rotate around the connecting shaft 113 in the direction of the opening of the limiting groove 123, so that the inner circumference of the limiting groove 123 on the latch 12 can be tightly pressed against the outer circumference of the positioning post 2, and the first component 3 can be stably locked to the second component 4, that is, the lower solar photovoltaic panel is locked to the lower support.

[0031] Reference Figure 6 and Figure 7As shown, when the lower solar photovoltaic panel needs to be opened, from the first position, pull the lever 13 extending from the side of the fixing part 11 outward by hand. Under the pull of the lever 13, the latch 12 rotates around the connecting shaft 113 in the opposite direction to the opening of the limiting groove 123. The lever 13 and the connecting part 125 on the latch 12 are rotatably connected, so that the limiting groove 123 on the latch 12 is disengaged from the positioning post 2. Then the first part 3 can be slid outward and pulled out to realize the open state between the first part 3 and the second part 4. After the lever 13 is released, the latch 12 rotates around the connecting shaft 113 in the direction of the opening of the limiting groove 123 under the pull of the tension spring 14. After the tension spring 14 is fully reset, it is the second position of the latch 12.

[0032] When the lower solar photovoltaic panel needs to be retracted, the first component 3 is slowly pushed by hand. When it moves to the point where the latch 12 contacts the positioning post 2, the latch 12 is pressed by the positioning post 2 and rotates around the connecting shaft 113 in the opposite direction to the opening of the limiting groove 123. At this time, the tension spring 14 connected to the second end 122 of the latch 12 is always in a stretched state. As the first component 3 slides inward, the positioning post 2 is embedded in the limiting groove 123 of the latch 12 to form a snap. The first component 3 and the second component 4 form a locked state. The overall structure is compact, the manual operation is convenient, the cost is saved, and the maintenance is easy.

[0033] 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. 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.
