[0002] The full name of MPPT controller is "maximum power point tracking" solar controller, which is an upgraded product of traditional solar charge and discharge controller. The MPPT controller is connected between electrical equipment, power supply and photovoltaic panels, and then the MPPT controller can detect the voltage generated by the solar panel and track the current in real time, so as to maximize the charging efficiency of the battery. Therefore, it is widely used in the field of photovoltaic power generation technology.

[0003] When the existing MPPT controller is in use, in order to better protect the electronic components inside the MPPT controller, a shell is installed on the outside of the MPPT controller, and the shell and the MPPT controller are connected with screws. This means that after a failure of the MPPT controller, it is necessary to use tools to rotate multiple screws to remove the shell from the outside of the MPPT controller, and then the internal electronic components can be inspected and maintained, which makes it inconvenient for users to quickly inspect and maintain the MPPT controller. Utility Model Content

[0004] The utility model aims to provide an MPPT controller with a line sub-control structure to solve the problem that the currently used MPPT controllers are not convenient for users to quickly perform maintenance and repair as mentioned in the above background technology.

[0013] Compared with the prior art, the beneficial effect of the utility model is that when the MPPT controller with a line sub-control structure is in use, the protrusion can be squeezed into the interior of the telescopic block, and the protrusion squeezes the rotating block. At the same time, the rotating block rotates and squeezes the telescopic spring in the middle. When the protrusion is completely retracted into the interior of the telescopic block, the telescopic block will be retracted into the interior of the sleeve through the resetting action of the movable spring. At this time, there is no telescopic block connected to the interior of the positioning block, and the outer shell can be removed from one side of the main unit, so that the user can inspect and maintain the MPPT controller conveniently. This is the use feature of the MPPT controller with a line sub-control structure.

[0014] 1. The MPPT controller with a line sub-control structure has a large number of electronic components installed inside when it is in use. In order to ensure that the MPPT controller can be used normally, when the MPPT controller fails, it needs to be repaired and maintained. At this time, the convex block can be squeezed, and then the convex block shrinks into the telescopic block, and the telescopic block shrinks from the through hole of the positioning block to the inside of the sleeve. At this time, the shell and the host can be disassembled, so that the user can quickly repair and maintain the inside of the host and facilitate the user to operate.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1 and Figure 2 The utility model provides a technical solution: an MPPT controller with a line sub-control structure, comprising: a host 1 and an interface 4, a control panel 2 is installed on one side of the host 1, a housing 3 is installed on the outer side of the host 1, and the interface 4 is opened at the bottom of the host 1;

[0024] A sleeve 5 is installed at the bottom of the shell 3, and a movable spring 6 is installed inside the sleeve 5 through a groove. A telescopic block 7 that passes through the sleeve 5 is connected to one side of the movable spring 6. A rotating block 8 is connected to the inside of the telescopic block 7 through a rotating shaft. A positioning block 9 is sleeved on the outer side of the telescopic block 7. The positioning block 9 and the host 1 are an integrated structure. A telescopic spring 10 is connected between the two groups of rotating blocks 8. The end of the rotating block 8 away from the telescopic spring 10 is connected to a protrusion 11 that passes through the telescopic block 7 through a slide groove. The telescopic block 7 forms a telescopic structure with the sleeve 5.

[0025] In specific implementation, when the MPPT controller with a line sub-control structure needs to be inspected and maintained, the convex block 11 can be squeezed. When the convex block 11 is squeezed, it will move toward the inside of the telescopic block 7 and squeeze one end of the rotating block 8 through the slide groove. The middle of the rotating block 8 is connected to the inside of the telescopic block 7 through a rotating shaft. At this time, one end of the rotating block 8 will rotate close to each other and squeeze the telescopic spring 10 in the middle of the rotating block 8. When the convex block 11 is completely retracted into the telescopic block 7, there is no convex block 11 to limit the telescopic block 7. Then the telescopic block 7 will be retracted into the inside of the sleeve 5 through the reset of the movable spring 6, and the telescopic block 7 will move out of the through hole of the positioning block 9, so that the telescopic block 7 is not connected to the through hole of the positioning block 9, and then the telescopic block 7 is retracted. Repeat the above steps and squeeze the remaining telescopic blocks 7 into the sleeve 5. At this time, the shell 3 can be separated from the host 1, so that the electronic components inside the host 1 are exposed to the outside, which is convenient for the user to inspect and maintain the MPPT controller. Conversely, when installing the shell 3, the telescopic block 7 can be pulled to insert the telescopic block 7 into the through hole of the positioning block 9, and the protrusion 11 can be squeezed again to shrink it into the telescopic block 7. When the protrusions 11 at both ends of the telescopic block 7 move to the outside of the positioning block 9, the rotating block 8 is driven by the telescopic spring 10 to rotate and reset, and the protrusion 11 is squeezed by the rotating block 8. After the protrusion 11 is squeezed to the outside of the telescopic block 7, the telescopic block 7 and the positioning block 9 can be limited, which is convenient for the user to quickly fix the shell 3 and the host 1 without affecting the normal use needs of the user.

[0026] See also Figure 2 and Figure 3 It can be seen that when in use, the protrusion 11 can be squeezed into the inside of the telescopic block 7 according to the use, and then the telescopic block 7 can be reset, thereby separating the host 1 from the shell 3, making it convenient for the user to inspect and maintain the electronic components inside the host 1.

[0027] A fixed block 12 is installed on the outside of the interface 4, and a first movable block 13 is provided at the bottom of the fixed block 12 through a slide groove, a connecting rod 14 is installed on the top of the first movable block 13, and a second movable block 15 is sleeved on the outside of the two groups of connecting rods 14, and a third movable block 16 is installed on the top of the connecting rod 14, and a connecting rod 17 is connected to the bottom of the third movable block 16 and the top of the second movable block 15 through a rotating shaft, and a connecting block 18 is connected between the two groups of connecting rods 17 through a rotating shaft, and a pull rod 19 passing through the fixed block 12 is connected to one side of the connecting block 18, and a telescopic rod 20 is installed at the end of the connecting block 18 away from the pull rod 19, and a compression spring 21 is installed inside, and two groups of connecting rods 14 are symmetrically installed about the center line of the first movable block 13.

[0028] In specific implementation, the MPPT controller with a line sub-control structure can be used to plug the wire into the bottom of the interface 4, and pull the pull rod 19 outward during the plugging process. The pull rod 19 drives the connecting block 18 to move. Since both ends of the connecting block 18 are connected to the connecting rod 17 through a rotating shaft, the connecting block 18 will pull the second movable block 15 and the third movable block 16 to move closer to each other through the rotating shaft, and the second movable block 15 moves upward, and the third movable block 16 moves downward, and the bottom of the third movable block 16 is connected to the first movable block 13 through the connecting rod 14. Under the action of the connecting rod 14, the first movable block 13 also moves downward. At the same time, since the connecting rod 14 passes through the second movable block 15 and is connected to the first movable block 13, the connecting rod 14 has no effect on the second movable block 15, that is, The first movable block 13 moves downward and the second movable block 15 moves upward, and then the wires to be connected can be connected to the interface 4. After the pull rod 19 is released, the connecting block 18 will drive the connecting block 18 to move in the opposite direction through the resetting action of the telescopic rod 20 and the compression spring 21 on the other side, and the third movable block 16 and the second movable block 15 move away from each other through the rotating shaft. At the same time, the first movable block 13 moves upward and the second movable block 15 moves downward, so as to clamp the wires in the interface 4 and prevent the wires from loosening. According to the above steps, the remaining wires are connected to the interface 4, and the other ends of each adjacent group of wires are connected to the circuit breaker. At this time, the MPPT controller can be controlled by the circuit breaker without interference with each other.

[0029] See also Figure 2 , Figure 4 and Figure 5 It can be seen that when in use, the wire can be connected to the position of the interface 4, and the wire can be limited by the first movable block 13 and the second movable block 15, so that the wire can be more stably connected to the circuit breaker, and the line control can be played at this time.

[0030] To sum up: when using the MPPT controller with a line sub-control structure, the entire MPPT controller can be installed on the wall to be fixed by bolts, and then connected to the circuit breaker at the bottom by wires, and the circuit breaker is connected to the photovoltaic panel, power supply and electrical appliances, so that the MPPT controller can be controlled, and when the MPPT controller is working, the data can be displayed on the display screen of the control panel 2, so that the user can observe it conveniently. This is the prior art and will not be elaborated on here. This is the use feature of the MPPT controller with a line sub-control structure. The content not described in detail in this description belongs to the prior art known to professional and technical personnel in this field.
