[0001] The utility model mainly relates to the field of photovoltaic assemblies, and in particular to a driving component and a photovoltaic system. Background Art

[0002] With the rapid development of the photovoltaic industry, my country's large-scale ground photovoltaic power stations, industrial and commercial distributed photovoltaic power stations, and household photovoltaic systems have been developed on a large scale. In recent years, due to the limitations of sites and power grids, photovoltaic development has encountered some problems, and it is urgent to develop other application scenarios to further expand the photovoltaic market. At present, the balcony of a residential building has not been taken seriously because of its small area, difficulty in installation, high cost and poor overall aesthetics. However, due to the large number of residential balconies and the broad market scale, with the innovative development of my country's photovoltaic technology, the cost of photovoltaic systems has been greatly reduced, and balcony photovoltaic products have shown high economic efficiency. However, the driving method of balcony-mounted photovoltaic modules in the prior art has the following problems: (1) The existing balcony photovoltaic modules are difficult to adjust the angle, and the operation inside the balcony is inconvenient. (2) For building balconies, especially high-rise building balconies, the installation of photovoltaic modules and drive modules requires outdoor high-altitude operations, and the safety risks of the operations are relatively high. (3) When the balcony width is large and multiple adjacent photovoltaic modules are used, it is necessary to drive the multiple photovoltaic modules separately, which is difficult.

[0005] In one embodiment of the present application, the motor connector has a main board, a first side panel and a second side panel, and the motor terminal seat has a first surface and a second surface opposite to each other in the second direction, wherein: the main board is suitable for connecting to the side frame, the main board has a first side edge and a second side edge opposite to each other in the second direction, the first side panel and the second side panel extend from the first side edge and the second side edge along the first direction respectively; the distance between the first side panel and the second side panel in the second direction is equal to the height of the motor terminal seat in the second direction, and when the motor connector and the motor terminal seat are connected, the first side panel and the second side panel are respectively attached to the first surface and the second surface.

When the motor connector is connected to the first connecting part or the second connecting part, the first opening and the second opening are opposite to the first fastening hole or the second fastening hole in the second direction.

[0008] In one embodiment of the present application, the height of the first side plate and the second side plate in a third direction perpendicular to the plane where the first direction and the second direction are located is less than the width of the first side edge and the second side edge in the third direction, and when the motor connector and the first connecting portion or the second connecting portion of the motor end seat are connected, the first side plate and the second side plate are respectively located at the parts of the first side edge and the second side edge away from the chain motor.

[0009] In one embodiment of the present application, there is a first distance between the two photovoltaic components in a first direction, and the length of the connector in the first direction is greater than the first distance.

[0053] In order to more clearly illustrate the technical solutions of the embodiments of the present application, the following is a brief introduction to the drawings required for the description of the embodiments. Obviously, the drawings described below are only some examples or embodiments of the present application. For ordinary technicians in this field, the present application can also be applied to other similar scenarios based on these drawings without creative work. Unless it is obvious from the language environment or otherwise explained, the same reference numerals in the figures represent the same structure or operation.

[0054] As shown in this application and claims, unless the context clearly indicates an exception, the words "a", "an", "an" and / or "the" do not refer to the singular and may also include the plural. Generally speaking, the terms "include" and "comprise" only indicate the inclusion of the steps and elements that have been clearly identified, and these steps and elements do not constitute an exclusive list. The method or device may also include other steps or elements.

[0055] Unless otherwise specifically stated, the relative arrangement, numerical expressions and numerical values ​​of the parts and steps set forth in these embodiments do not limit the scope of the present application. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, method and equipment known to those of ordinary skill in the relevant field may not be discussed in detail, but in appropriate cases, the technology, method and equipment should be considered as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so that once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0056] In the description of the present application, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present application; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0057] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0058] In addition, it should be noted that the use of words such as "first" and "second" to define components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above words have no special meaning and cannot be understood as limiting the scope of protection of this application. In addition, although the terms used in this application are selected from well-known and commonly used terms, some terms mentioned in the specification of this application may be selected by the applicant at his or her discretion, and their detailed meanings are explained in the relevant parts of the description of this article. In addition, it is required to understand this application not only by the actual terms used, but also by the meaning implied by each term.

[0059] It should be understood that when a component is referred to as being "on another component," "connected to another component," "coupled to another component," or "contacting another component," it may be directly on, connected to, coupled to, or contacting the other component, or there may be intervening components. In contrast, when a component is referred to as being "directly on another component," "directly connected to," "directly coupled to," or "directly contacting" another component, there are no intervening components. Similarly, when a first component is referred to as being "electrically in contact with" or "electrically coupled to" a second component, there is an electrical path between the first component and the second component that allows current to flow. The electrical path may include capacitors, coupled inductors, and / or other components that allow current to flow, even without direct contact between conductive components.

[0060] Figure 1 It is a side view of a driving component and a photovoltaic component 20 combined in the present application. Figure 2 This is a partial front view of a driving assembly and a photovoltaic assembly 20 of the present application. Figure 1-2As shown, the present application provides a driving assembly suitable for driving two adjacent photovoltaic modules 20 in a balcony photovoltaic system in a first direction AA' to rotate synchronously, and a longitudinal beam 30 extending in a second direction BB' perpendicular to the first direction is provided between the two adjacent photovoltaic modules 20. In the actual installation process, the longitudinal beam 30 needs to be first installed on the outside of the balcony load-bearing surface, and the two adjacent photovoltaic modules 20 are then hung on both sides of the longitudinal beam 30. In this preferred embodiment, the longitudinal beam 30 is a U-shaped rod, and the frame 21 of the photovoltaic module 20 has a side groove 22 (refer to Figure 6 , 9 shown).

[0061] The drive assembly provided by the present application includes a chain motor 10, two motor connectors 140 and a plug-in connector 150. The chain motor 10 is arranged on the longitudinal beam 30. Specifically, in this embodiment, the chain motor 10 is arranged in the slot of the U-shaped rod, and the chain motor 10 includes a housing 110 and a bending chain 120. When the drive motor is not working, the bending chain 120 is stored in the housing 110. During use, the bending chain 120 can be extended or retracted from the inside of the housing 110. And the bending chain 120 is away from the first end of the housing 110 (such as Figure 1 A motor end seat 130 is provided at the left end as shown. Figure 3 1 is a top view of a motor end seat 130 of the present application. Figure 1-3 As shown, the motor end seat 130 includes an abutting portion 131 and first connecting portions 132 (such as Figure 2 left side) and a second connecting portion 133 (as shown Figure 2 As shown on the right side, the first end of the bending link 120 is connected to the abutting portion 131 .

[0062] Figure 4 is a side view of a motor connector 140 of the present application, Figure 5 is a top view of a motor connector 140 of the present application, Figure 6 This is a top view of a driving assembly and a photovoltaic assembly 20 of the present application. Figure 2 , 4 -6, the two motor connectors 140 are respectively suitable for being fixed on the side frames 21 of the two photovoltaic modules 20, and the two motor connectors 140 are respectively suitable for being connected to the first connection part 132 and the second connection part 133 of the motor terminal 130. In other words, the side frames 21 of the two adjacent photovoltaic modules 20 are respectively connected to the first connection part 132 and the second connection part 133 of the motor terminal 130 through the two motor connectors, thereby completing the flexible connection between the chain motor 10 and the photovoltaic module 20. When the bending chain 120 protrudes from the housing 110, it will push the motor terminal 130, and then push the photovoltaic module 20 to rotate through the motor connector 140.

[0063] In this preferred embodiment, the motor terminal 130 further has a first surface 134 and a second surface 135 opposite to each other in the second direction BB', and the motor connector 140 has a main board 141, a first side plate 142 and a second side plate 143, wherein the main board 141 is suitable for connecting to the side frame 21 of the photovoltaic module 20, and the first side plate 142 and the second side plate 143 are respectively suitable for connecting to the first surface 134 and the second surface 135 of the motor terminal 130. Specifically, the main board 141 has a first side edge 144 and a second side edge 145 opposite to each other in the second direction BB', and the first side plate 142 and the second side plate 143 extend from the first side edge 144 and the second side edge 145 along the first direction AA'. Moreover, in this embodiment, the distance between the first side plate 142 and the second side plate 143 in the second direction is equal to the height of the motor terminal seat 130 in the second direction BB'. When the motor connector 140 and the motor terminal seat 130 are connected, the first side plate 142 and the second side plate 143 fit exactly against the first surface 134 and the second surface 135 of the motor terminal seat 130.

[0064] In order to further complete the cooperation between the motor connector 140 and the motor end seat 130, the first connecting portion 132 and the second connecting portion 133 of the motor end seat 130 in this embodiment further have a first fastening hole 136 and a second fastening hole 137, respectively. Specifically, the first fastening hole 136 penetrates the first connecting portion 132 along the second direction BB', and the second fastening hole 137 penetrates the second connecting portion 133 along the second direction BB'. Correspondingly, the first side plate 142 and the second side plate 143 of each motor connector 140 in this embodiment respectively have a first opening 146 and a second opening 147 that are opposite in the second direction. When the motor connector 140 is connected to the first connecting portion 132 or the second connecting portion 133, the first opening 146 and the second opening 147 are opposite to the first fastening hole 136 or the second fastening hole 137 in the second direction BB'.

[0065] It is understandable that, since the motor end seat 130 is symmetrically designed, both sides thereof can be connected to the motor connector 140 of the same form, so as to Figure 2 , 6 Taking the motor connector 140 connected to the first connecting portion 132 on the left side as an example, the bolt 40 passes through the first opening 146, the first fastening hole 136 and the second opening 147 in sequence to fix the motor connector 140 and the first connecting portion 132. Figure 2 , 6 Taking the motor connector 140 connected to the second connecting portion 133 on the right side as an example, the bolt 40 passes through the first opening 146 , the second fastening hole 137 and the second opening 147 in sequence to complete the fixing of the motor connector 140 and the second connecting portion 133 .

[0066] Further, in this embodiment, the height of the first side plate 142 and the second side plate 143 in the third direction CC' perpendicular to the plane where the first direction AA' and the second direction BB' are located is smaller than the width of the first side edge 144 and the second side edge 145 in the third direction CC', and when the motor connector 140 is connected to the first connecting portion 132 or the second connecting portion 133 of the motor end seat 130, the first side plate 142 and the second side plate 143 are respectively located at the portion of the first side edge 144 and the second side edge 145 away from the chain motor 10. Figure 6 As shown, this arrangement can increase the distance between the first side plate 142, the second side plate 143 and the longitudinal beam 30 when the motor connector 140 and the motor terminal 130 are connected, thereby expanding a longitudinal space along the second direction BB' to accommodate other components required for the photovoltaic system and save space.

[0067] Figure 7 This is a front view of a connector 150 and a photovoltaic module 20 of the present application. Figure 8 This is a bottom view of a connector 150 and a photovoltaic module 20 of the present application. Fig. 9 This is a side view of a connector 150 and a photovoltaic module 20 of the present application. Figure 7-9 As shown, the plug-in component 150 in the driving assembly provided by the present application has a first plug-in portion 151 and a second plug-in portion 152 connected along a first direction, which are respectively suitable for matching with the lower frames 21 of the two photovoltaic assemblies 20. Figure 7-8 As shown in the example, the first plug-in portion 151 of the plug-in component 150 is suitable for cooperating with the lower frame 21 of the left photovoltaic assembly 20, and the second plug-in portion 152 is suitable for cooperating with the lower frame 21 of the right photovoltaic assembly 20. Moreover, the shapes of the first plug-in portion 151 and the second plug-in portion 152 are different, and the cooperating modes of the two with the frame 21 are also different: the first plug-in portion 151 is suitable for sliding connection with the lower frame 21 in the first direction AA', and the second plug-in portion 152 is suitable for overlapping with the lower frame 21 in the second direction BB'.

[0068] Specifically, the first plug-in portion 151 and the second plug-in portion 152 have a common structure in that they both have a main body 153. The difference is that the second plug-in portion 152 only has the main body 153, while the first plug-in portion 151 has a first ridge 154 and a second ridge 155 in addition to the main body 153. The first ridge 154 and the second ridge 155 are respectively located on two side surfaces of the main body 153 in the third direction CC' and protrude outward. In other words, in the third direction CC', the height of the first plug-in portion 151 is greater than that of the second plug-in portion 152.

[0069] For further reference, Figure 7-8As shown, in the actual installation process, the first plug-in portion 151 of the plug-in component 150 needs to be slid into the side groove 22 of the left lower frame 21 along the first direction AA' (as shown in FIG. Fig. 9 As shown in FIG. 1 , the first convex strip 154 ​​and the second convex strip 155 are respectively in contact with the top and bottom of the side groove 22. After the first plug-in portion 151 and the left photovoltaic assembly 20 are matched, it is only necessary to Figure 7-8 The right photovoltaic assembly 20 shown is placed from top to bottom in the second direction BB', so that the second plug-in portion 152 and the side groove 22 can be matched. At this time, the upper notch and the lower notch of the side groove 22 are respectively abutted against the two side surfaces of the main body 153 in the third direction CC'. It can be understood that in this embodiment, the distance between the two side surfaces of the main body 153 in the third direction CC' is equal to the distance between the upper notch and the lower notch of the side groove 22, so there will be no obstruction during the overlapping process.

[0070] It should be noted that there is a first distance D1 between two photovoltaic modules 20 in the first direction AA′. To ensure that the connector 150 can simultaneously connect two adjacent photovoltaic modules 20 , the length D2 of the connector 150 in the first direction is greater than the first distance D1 .

[0071] In such Figure 7-9 In the illustrated embodiment, the main body 153 of the first connector 150 further has two third fastening holes 156 extending along the first direction, and the third fastening holes 156 are suitable for allowing the bolts 40 to pass through so as to combine the first connector 150 and the frame 21. In some other embodiments, the number of the third fastening holes 156 may be less or more, and the present application does not make any specific limitation here.

[0072] The present application also provides a photovoltaic system, comprising at least two photovoltaic modules 20 and at least one driving module as in any of the above embodiments, wherein the driving module is adapted to connect two photovoltaic modules 20 adjacent to each other in a first direction and drive the two photovoltaic modules 20 to rotate synchronously. It is understandable that two adjacent photovoltaic modules 20 can be controlled in linkage by a driving module, and as the number of photovoltaic modules 20 increases, the number of driving modules also needs to increase accordingly.

Obviously, for those skilled in the art, the above utility model disclosure is only used as an example and does not constitute a limitation of the present application. Although not explicitly stated here, those skilled in the art may make various modifications, improvements and corrections to the present application.
