Description

Technical Field

[0001] This utility model relates to the field of photovoltaic equipment technology, and specifically to a photovoltaic optimizer. Background Technology

[0002] Photovoltaic optimizers are an important type of module-level power electronics (MLPE) device, primarily used to optimize the power generation efficiency of individual or string photovoltaic modules in real time.

[0003] In practical applications of photovoltaic power plants, the wiring requirements differ due to the different models of photovoltaic modules and their different arrangements (such as different orientations).

[0004] However, traditional photovoltaic optimizers use fixed output cable positions and directions, and their interfaces can only be adapted to the wiring connections of a single or a few types of photovoltaic modules. For other photovoltaic modules, additional extension cables are required to achieve the connection, which is time-consuming, labor-intensive, and increases costs. Utility Model Content

[0046] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0047] The following is combined with Figures 1 to 15 The following describes embodiments of the present invention.

[0048] According to an embodiment of the present invention, a photovoltaic optimizer is provided, comprising: a fixing component 1; a device body 2 rotatably connected to the fixing component 1; a first latching part 3 disposed on the fixing component 1 and located on the side of the fixing component 1 close to the device body 2; and a second latching part 4 disposed on the device body 2 and located on the side of the device body 2 close to the fixing component 1; wherein, multiple first latching parts 3 are provided, and the multiple first latching parts 3 are spaced apart; the second latching part 4 is detachably connected to any one of the first latching parts 3, and is adapted to limit and fix the device body 2 after rotating it by a certain angle.

[0049] It should be noted that the fixing component 1 is fixed to the photovoltaic module on the side away from the device body 2, that is, the fixing plate 11 is fixed to the photovoltaic module.

[0050] Combination Figure 1 As shown, the device body 2 is provided with a terminal 23, which is located on one side of the device body 2 surrounding the first direction. Cables are led out from the terminal 23 to connect to the photovoltaic module.

[0051] Combination Figure 1 and Figure 2 As shown, multiple first latching parts 3 are evenly spaced around the first direction, that is, multiple first latching parts 3 are arranged in a rotationally symmetrical manner around the first direction; the interval angle between adjacent first latching parts 3 can be 90 degrees.

[0052] Specifically, the photovoltaic optimizer has a fixed state and a switching state:

[0053] When the photovoltaic optimizer is in a fixed state, the second latching part 4 on the device body 2 latches onto one of the first latching parts 3 to limit and fix the device body 2. At this time, the device body 2 cannot rotate relative to the fixed component 1. With the cooperation of the first latching part 3 and the second latching part 4, the device body 2 is limited and fixed on the fixed component 1, so that the direction and position of the terminal 23 are limited and fixed.

[0054] When the photovoltaic optimizer is in the switching state, the second latching part 4 of the device body 2 is disengaged from the first latching part 3 connected to it when it is in the fixed state, and the first latching part 3 does not cooperate with any of the second latching parts 4. At this time, the device body 2 can rotate relative to the fixed component 1 around the first direction, and the direction and position of the terminal 23 change with the rotation of the device body 2.

[0055] In specific usage, combined with Figure 1 , Figure 13 , Figure 14 and Figure 15 As shown, Figure 1With terminal 23 in its initial orientation and position, and terminal 23 facing downwards, terminal 23 (the interface of the photovoltaic optimizer) can be adapted to the wiring connection of photovoltaic modules that are positioned slightly downwards. Figure 13 The photovoltaic optimizer shown is in Figure 1 Based on this, the device body 2 rotates 90 degrees clockwise relative to the fixed component 1, and the wiring terminal 23 faces to the left. At this time, the wiring terminal 23 can be adapted to the wiring connection of the photovoltaic module that is biased to the left. Figure 14 The photovoltaic optimizer shown is in Figure 1 Based on this, the device body 2 rotates 180 degrees clockwise relative to the fixed component 1, with the wiring terminal 23 facing upwards. At this time, the wiring terminal 23 can be adapted to the wiring connection of the photovoltaic module that is arranged on the upward side. Figure 15 The photovoltaic optimizer shown is in Figure 1 Based on this, the device body 2 rotates 270 degrees clockwise relative to the fixed component 1, and the wiring terminal 23 faces to the right. At this time, the wiring terminal 23 can be adapted to the wiring connection of the photovoltaic module that is biased to the right.

[0056] Furthermore, in Figure 1 , Figure 13 , Figure 14 and Figure 15 The specific method for switching the direction and position of terminal 23 is as follows: Figure 1 The photovoltaic optimizer shown is in its initial direction and position. The second latching part 4 of the device body 2 latches onto one of the first latching parts 3, and the device body 2 is fixed at the fixed component 1. The photovoltaic optimizer is in a fixed state at this time. In order to adapt the photovoltaic optimizer to the wiring connection of photovoltaic modules with other arrangement forms, the second latching part 4 of the device body 2 is removed from the first latching part 3 that it is latched onto. Then the device body 2 can rotate around the first direction relative to the fixed component 1, and the photovoltaic optimizer is in a switching state at this time. It can be rotated at a certain angle (90 degrees, 180 degrees or 270 degrees) according to the actual installation requirements, so that the second latching part 4 of the device body 2 latches onto another first latching part 3. The device body 2 is fixed, and the photovoltaic optimizer returns to the fixed state to change the direction and position of the wiring terminal 23 to adapt it to the arrangement form of the photovoltaic module, thereby eliminating the need for additional extension cables and saving time and effort.

[0057] It should be noted that the device body 2 is rotatably connected to the fixed component 1 by means of the connecting ring 5. The first snap-fit ​​part 3 and the second snap-fit ​​part 4 only serve to snap and limit the fixation, so that the photovoltaic optimizer can switch between the fixed state and the switching state.

[0058] In this embodiment, through the rotatable connection between the device body 2 and the fixed component 1, and the multiple first snap-fit ​​parts 3 (e.g., 90-degree intervals) evenly spaced around the first direction, the device body 2 can be limited and fixed at angles such as 0 degrees (initial direction), 90 degrees, 180 degrees, and 270 degrees, so that the direction of the wiring terminal 23 can be flexibly adjusted with rotation. This can adapt to the arrangement of photovoltaic module wiring ports in different directions, without the need to replace the equipment or make additional adjustments to the cable routing due to differences in photovoltaic module layout, thus improving installation adaptability. A single photovoltaic optimizer can be adapted to install photovoltaic modules with various different layouts.

[0059] In some embodiments, the first latching portion 3 is a groove; the second latching portion 4 includes a first elastic member 41 and a first clearance groove 42; the first clearance groove 42 is recessed in the device body 2; one end of the first elastic member 41 is integrally formed with the device body 2 and corresponds to the first clearance groove 42; the other end of the first elastic member 41 has a first protrusion 43 on the side near the fixing component 1; wherein, the side of the first elastic member 41 facing away from the fixing component 1 is spaced apart from the wall of the first clearance groove 42.

[0060] It should be noted that, in combination Figure 3 As shown, the first clearance groove 42 is recessed and formed on the side of the device body 2 near the fixing component 1. The first clearance groove 42 provides space for the first elastic member 41 to retract, and the first elastic member 41 extends beyond the edge of the device body 2.

[0061] Specifically, when the photovoltaic optimizer is in a fixed state, the first protrusion 43 is engaged in the groove (first engaging part 3), so that the second engaging part 4 engages with the first engaging part 3, and the device body 2 is limited and fixed. When the photovoltaic optimizer is in a switching state, the first elastic member 41 is pressed down along the first direction toward the fixed component 1, so that the first elastic member 41 enters the first clearance groove 42, and the first protrusion 43 retracts from the groove, so that the second engaging part 4 and the first engaging part 3 are no longer engaged. The device body 2 rotates relative to the fixed component 1 until the device body 2 rotates to a certain angle, and the second engaging part 4 corresponds to another first engaging part 3, releasing the pressure on the first elastic member 41. Since one end of the first elastic member 41 is integrally set with the device body 2 and the first elastic member 41 is elastic, the first elastic member 41 recovers under the action of elastic restoring force, and the first protrusion 43 engages in the current first engaging part 3.

[0062] In this embodiment, the second locking part 4 adopts a combination structure of elastic element and relief groove. When switching states, it is only necessary to press down the first elastic element 41 (such as pressing with a finger) to make the first protrusion 43 retract from the groove (first locking part 3) and release the limitation on the device body 2. After rotating to the target angle, the elastic element is released and it automatically resets by its own elastic restoring force. The first protrusion 43 is locked into the new groove to complete the limitation and fixation. No other tools are needed, simplifying the operation steps and improving work efficiency.

[0063] In some embodiments, the fixing component 1 includes a fixing plate 11 and a positioning ring 12, the positioning ring 12 being fixed to the side of the fixing plate 11 near the device body 2; the groove is provided on the positioning ring 12, and the opening of the groove faces the device body 2.

[0064] Combination Figure 3 and Figure 4 As shown, multiple grooves are arranged symmetrically around the first direction at the positioning ring 12. The specific number can be, but is not limited to, four, and can be determined according to actual needs.

[0065] In some embodiments, the positioning ring 12 includes a first ring portion 121 and a second ring portion 122; the first ring portion 121 protrudes in a first direction relative to the second ring portion 122 to form a step 13 between the first ring portion 121 and the second ring portion 122; the first ring portion 121 is attached to and fixed to the fixing plate 11, and the second ring portion 122 is spaced apart from the surface of the fixing plate 11.

[0066] Combination Figure 6 As shown, the first ring portion 121 is located around the second ring portion 122, and the first ring portion 121 protrudes in the first direction relative to the second ring portion 122 to form a step 13. The step 13 serves as the mounting position for the connecting ring 5. The distance between the second ring portion 122 and the surface of the fixing plate 11 is greater than or equal to the thickness of the connecting ring 5 in the first direction. A groove is formed on the side of the first ring portion 121 near the device body 2.

[0067] In some embodiments, the photovoltaic optimizer further includes a connecting ring 5, which is snapped onto the step 13 and located between the second ring portion 122 and the fixing plate 11; the second ring portion 122 has a ring opening 14 that extends through in a first direction; the connecting ring 5 is rotatable relative to the fixing component 1 about the first direction; wherein, the connecting ring 5 has a connecting portion 51 on the side near the device body 2, the connecting portion 51 passes through the ring opening 14 and connects to the device body 2, so that the device body 2 is rotatable relative to the fixing component 1 about the first direction.

[0068] Combination Figure 4As shown, the connecting ring 5 is snapped onto the positioning ring 12 and located at the step 13 of the positioning ring 12. The connecting ring 5 can rotate relative to the positioning ring 12 in a first direction. The ring body of the connecting ring 5 extends beyond the edge of the ring opening 14, and a connecting part 51 is provided at the extended part. The connecting part 51 is located on the side of the connecting ring 5 closer to the device body 2 and protrudes relative to the connecting ring 5. The connecting part 51 passes through the ring opening 14, and the side of the connecting part 51 away from the connecting ring 5 is fixed to the device body 2. The fixing method can be ultrasonic welding. Furthermore, after the device body 2 is fixed to the connecting part 51, since the connecting ring 5 is sandwiched between the positioning ring 12 and the fixing plate 11, the device body 2 is connected to the fixing component 1, and the device body 2 can rotate relative to the fixing component 1 in a first direction.

[0069] In this embodiment, the connecting ring 5 is an independent rotating component, which is engaged at the step 13 of the fixing component 1 and sandwiched between the second ring 122 and the fixing plate 11. At the same time, the connecting ring 5 is fixed to the device body 2 to prevent the device body 2 from detaching from the fixing component 1 and to ensure the stability of the device body 2 during rotation.

[0070] In some embodiments, the device body 2 is provided with a fixing ring 21 on the side near the fixing component 1; the fixing ring 21 is integrally formed with the device body 2 and protrudes relative to the device body 2; the positioning ring 12 is sleeved on the periphery of the fixing ring 21; the fixing ring 21 is provided with a fixing groove 211 on the side away from the device body 2, and the connecting part 51 is engaged in the fixing groove 211 and fixed.

[0071] Combination Figure 6 , Figure 7 and Figure 11 As shown, the positioning ring 12 is sleeved around the periphery of the fixed ring 21. The fixed ring 21 is integrally formed with the equipment body 2. The fixed ring 21 can rotate relative to the positioning ring 12 to avoid affecting the rotation of the equipment body 2. The connecting part 51 is strip-shaped and is arranged around the center of the connecting ring 5. The fixing groove 211 is strip-shaped and the groove body is adapted to the connecting part 51. The connecting part 51 is snapped into the fixing groove 211 and fixed together by ultrasonic welding.

[0072] It should be noted that the fixing ring 21 has a notch 213 formed in part of the ring body to accommodate the first elastic member 41; one end of the first elastic member 41 is connected to the device body 2 and extends out after passing through the notch 213.

[0073] In some embodiments, the fixing ring 21 is provided with a plurality of snap-fit ​​grooves 212 spaced apart on its periphery, and the positioning ring 12 is provided with a third snap-fit ​​part 6, which is detachably connected to any of the snap-fit ​​grooves 212.

[0074] Combination Figure 6As shown, when the device body 2 rotates around the first direction, the fixed ring 21 rotates accordingly. By setting a matching third snap-fit ​​part 6 and snap-fit ​​groove 212 between the fixed ring 21 and the positioning ring 12, the device can be positioned during rotation.

[0075] It should be noted that the multiple snap-fit ​​slots 212 are arranged in a rotationally symmetrical manner around the first direction, and the interval angle between adjacent snap-fit ​​slots 212 is 90 degrees, which is consistent with the interval angle between adjacent first snap-fit ​​parts 3.

[0076] Specifically, when the device body 2 is in a fixed state, the second latching part 4 latches with one of the first latching parts 3, and the third latching part 6 latches with one of the latching slots 212; when the device body 2 is in a switching state, the third latching part 6 disengages from the latching slot 212 it is in, until the device body 2 rotates a certain angle, so that the second latching part 4 latches with another first latching part 3, and the third latching part 6 latches with another latching slot 212.

[0077] In some embodiments, the third snap-fit ​​portion 6 includes a second elastic member 61 and a second clearance groove 62; the second clearance groove 62 is formed by recessing a portion of the first ring portion 121 and the second ring portion 122; the second elastic member 61 is connected to the second ring portion 122 and is correspondingly disposed to the second clearance groove 62; the second elastic member 61 has a second protrusion 63 on the side near the fixing ring 21, and the second protrusion 63 engages with the snap-fit ​​groove 212; the side of the second elastic member 61 facing away from the fixing ring 21 is spaced apart from the second clearance groove 62.

[0078] Combination Figure 6 , Figure 7 and Figure 9 As shown, the second clearance groove 62 is recessed and formed on the side of the positioning ring 12 near the fixing ring 21, and the second clearance groove 62 provides space for the second elastic member 61 to retract; the second ring portion 122 of the positioning ring 12 is located on the periphery of the fixing ring 21.

[0079] Specifically, when the photovoltaic optimizer is in a fixed state, the second protrusion 63 is engaged in one of the engagement slots 212; when the photovoltaic optimizer is in a switching state, the fixing ring 21 rotates with the equipment body 2, and the positioning ring 12 is fixed to the fixing plate 11, that is, the fixing ring 21 rotates relative to the positioning ring 12, and the outer wall of the fixing ring 21 pushes up the second protrusion 63 and the second elastic member 61, so that the second elastic member 61 enters the second clearance groove 62, and the second protrusion 63 disengages from the engagement slot 212; when the equipment body 2 rotates at a certain angle, during the rotation process, the other engagement slot 212 at the fixing ring 21 corresponds to the second protrusion 63, and under the action of the elastic force of the second elastic member 61, the second protrusion 63 engages in the engagement slot 212, and the second protrusion 63 collides with the inner wall of the engagement slot 212, which produces a certain feedback effect on the operator.

[0080] In some embodiments, the device body 2 is provided with a positioning protrusion 22 on the side near the fixing component 1, and a positioning groove 52 is formed in a recessed part of the connecting ring 5, and the positioning groove 52 is engaged with a part of the wall of the positioning protrusion 22.

[0081] Combination Figure 6 As shown, the positioning protrusion 22 can be disc-shaped, and the positioning groove 52 can be arc-shaped. The positioning groove 52 cooperates with part of the arc-shaped peripheral wall of the positioning protrusion 22, which plays a positioning role when installing the connecting ring 5.

[0082] In some embodiments, combined with Figures 1 to 4 As shown, the positioning ring 12 is fixed to the fixing plate 11 by means of fasteners 7, which can be screws. The positioning ring 12 has a mounting hole 123, which can be a screw hole. The fasteners 7 pass through the fixing plate 11 and are fixed in conjunction with the mounting hole 123.

[0083] In some embodiments, at least two second latching portions 4 are arranged in a rotationally symmetrical manner about a first direction, and the interval angle between adjacent second latching portions 4 is a multiple of the interval angle between adjacent first latching portions 3, such as 90 degrees or 180 degrees. In this embodiment, there are two second latching portions 4 and four first latching portions 3. The interval angle between adjacent second latching portions 4 is 180 degrees, and the interval angle between adjacent first latching portions 3 is 90 degrees.
