Description

Technical Field

[0001] This application relates to the field of photovoltaic system technology, and in particular to a balcony bracket, bracket system and photovoltaic system. Background Technology

[0002] A balcony photovoltaic (PV) system is a compact solar power generation system designed specifically for residential use. It is typically installed on balconies, walls, or roofs and uses photovoltaic modules to provide power for self-consumption or grid supply. Balcony PV systems are widely popular in urban areas due to their flexible installation, low-voltage safety, and intelligent management features.

[0003] However, the inventors believe that the aforementioned technologies have the following drawbacks: Traditional balcony photovoltaic systems require two sets of corner brackets to fix each photovoltaic module during installation, resulting in low installation efficiency. Furthermore, the pressing structure needs to be completely disassembled during installation and removal, which can easily cause parts to fall off, making secondary disassembly and maintenance difficult and posing certain safety hazards.

[0038] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used in the description of this application is for the purpose of describing specific embodiments only and is not intended to limit this application; the terms "comprising," "including," "having," "containing," etc., in the description, claims, and accompanying drawings of this application are open-ended terms.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0039] In the description of this application, it should be understood that the terms "center", "lateral", "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0040] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components.

[0041] In this application, the term "implementation" means that a specific feature, structure, or characteristic described in connection with an implementation can be included in at least one implementation of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same implementation, nor is it a separate or alternative implementation mutually exclusive with other implementations. Those skilled in the art will understand, explicitly and implicitly, that the implementations described in this application can be combined with other implementations.

[0042] As mentioned above, it should be emphasized that when the term "comprising / including" is used in this specification, it is used to explicitly indicate the presence of the stated feature, integer, step, or component, but does not exclude the presence or addition of one or more other features, integers, steps, components, or groups of features, integers, steps, or components. As used in this application, the singular forms "a," "an," and "the" also include the plural forms, unless the context clearly indicates otherwise.

[0043] One or more embodiments of this application disclose a balcony bracket, see reference Figures 1 to 19 The system includes a support assembly 1, a purlin 2, and a pressure block kit 3. The support assembly 1 is adapted to connect to the balcony railing 4. The purlin 2 is mounted on the support assembly 1. The pressure block kit 3 is detachably mounted on the purlin 2. The purlin 2 is provided with a first mounting cavity 21 and a second mounting cavity 22. The pressure block kit 3 includes an upper pressure block 31, a lower pressure block 32, a locking rod 33, and a locking device 34. The lower pressure block 32 and the first mounting cavity 21 are engaged. The locking device 34 and the second mounting cavity 22 are engaged. The locking rod 33 is adapted to pass through the upper pressure block 31, the lower pressure block 32, and the purlin 2 in sequence and is connected to the locking device 34. The upper pressure block 31 is adapted to move along the locking rod 33. The locking rod 33 is adapted to move relative to the locking device 34 to limit the movement distance between the upper pressure block 31 and the lower pressure block 32. The above structure can achieve the anti-detachment and anti-scattering effect of the pressure block kit 3 and improve the disassembly and assembly efficiency of the pressure block kit 3.

[0044] like Figure 10 , 11In the embodiments shown in 14 and 15, by changing the relative position between the locking lever 33 and the locking device 34, the locking lever 33 can move the upper pressure block 31 closer to the lower pressure block 32 to lock the supported object, or it can move the upper pressure block 31 away from the lower pressure block 32 to release the lock on the supported object.

[0045] like Figures 4 to 7 In the illustrated embodiment, the locking rod 33 is a screw, and the locking device 34 is a nut. The top of the locking rod 33 is larger than the rod body, so the top of the locking rod 33 is suitable for restricting the release of the upper pressure block 31. The lower part of the locking rod 33 is suitable for threaded connection with the locking device 34. Since the locking device 34 is engaged in the second mounting cavity 22, when the locking rod 33 rotates, the locking device 34 will move along the insertion direction of the locking rod 33 if it wants to follow the rotation of the locking rod 33. At this time, the locking device 34 is suitable for contact engagement with the purlin 2, so that the locking device 34 is restricted in the second mounting cavity 22 of the purlin 2. Therefore, when the locking rod 33 and the locking device 34 are threadedly connected, the relative movement between the locking rod 33 and the locking device 34 can be achieved by rotating the locking rod 33. At the same time, the screw design of the locking rod 33 can operate only the top of the locking rod 33, thereby realizing the unlocking and locking of the pressure block kit 3, making disassembly and assembly simpler, more convenient and efficient.

[0046] like Figures 4 to 7 In the illustrated embodiment, one or both sides of the lower pressure block 32 extend to the outer side of the purlin 2 to form a wing plate portion 321. The upper pressure block 31 has a pressing portion 311 formed on one or both sides of the wing plate portion 321. The pressing portion 311 is adapted to cooperate with the wing plate portion 321 to clamp the supported object. The function of the wing plate portion 321 is to increase the contact area between the lower pressure block 32 and the supported object, facilitate the installation of the supported object, improve the installation efficiency, and reduce the risk of accidental falling. The clamping method of the pressing portion 311 and the wing plate portion 321 can adapt to the supported object of different thicknesses and can reduce the installation problems caused by the different shapes of the supported object.

[0047] like Figures 4 to 7 In the embodiment shown, an upright plate 3211 is provided at the inner end of the wing plate portion 321. The upright plate 3211 is adapted to restrict the supported object from approaching the locking rod 33. The upright plate 3211 can achieve lateral sliding limit of the supported object. Here, lateral sliding refers to the sliding of the supported object along the width direction of the purlin 2, which improves the installation stability of the supported object and reduces the probability of the supported object contacting the locking rod 33 and other structures, thereby improving the structural stability.

[0048] like Figures 4 to 7In the embodiments shown in 10 to 15, the upper pressure block 31 is further adapted to rotate relative to the lower pressure block 32 along the locking rod 33. The distance H1 from the central axis of the locking rod 33 to the upright plate 3211 is less than the distance H2 from the central axis of the locking rod 33 to the end of the pressing part 311, and is not less than half of the width H3 of the upper pressure block 31. The purpose of this design is that after the locking rod 33 moves and the upper pressure block 31 is loosened, the upper pressure block 31 can rotate 90° to leave the space above the support object that abuts the upright plate 3211, so that the support object can be directly removed to the outside, effectively reducing the difficulty of disassembling and assembling the support object. Similarly, after the support object is installed, the upper pressure block 31 can be rotated back 90° to re-lock the support object.

[0049] like Figures 4 to 7 In the embodiment shown, the inner end of the crimping part 311 is provided with a blocking part 3111. The blocking part 3111 is adapted to restrict the support object from approaching the locking rod 33. The blocking part 3111 can be used to assist the upright plate part 3211 in restricting the lateral sliding of the support object and improving the stability of the pressure block kit 3 in fixing the support object.

[0050] like Figure 18 and 19 In the embodiment shown, a boss 3212 is provided on the outer end of the wing plate portion 321 facing the upper pressure block 31. The boss 3212 is adapted to restrict the longitudinal movement of the supported object, and the boss 3212 is adapted to cooperate with the upright plate portion 3211 and / or the blocking portion 3111 to restrict the lateral movement of the supported object.

[0051] Specifically, when the supported object is a photovoltaic module 5, the boss 3212, together with the upright plate 3211 and / or the blocking part 3111, can restrict the photovoltaic module 5 on both the inner and outer sides of the frame, thereby further restricting the lateral sliding. Here, lateral sliding refers to the sliding of the photovoltaic module 5 along the width direction of the purlin 2.

[0052] Furthermore, by placing the pressure block kit 3 at the corner of the frame of the photovoltaic module 5, the protrusion 3212 is close to or even abuts against the opposite sides of the frame of the photovoltaic module 5 along the length of the purlin 2, which can also limit the longitudinal sliding of the photovoltaic module 5. Here, longitudinal sliding refers to the sliding of the photovoltaic module 5 along the length of the purlin 2.

[0053] As can be seen, this application achieves multi-directional locking of the frame of the photovoltaic module 5 through the cooperation of the upright plate 3211 (and / or the blocking part 3111) and the boss 3212, thereby achieving complete fixation of the photovoltaic module 5 in the support plane of the purlin 2, reducing or even eliminating the sliding of the photovoltaic module 5 on the purlin 2, thereby improving the overall structural stability.

[0054] like Figure 9In the embodiment shown, the upright plate portion 3211 contacts the supported object before the blocking portion 3111, that is, the distance between the outer sides of the two upright plate portions 3211 of the lower pressure block 32 is greater than the distance between the outer sides of the two blocking portions 3111 of the upper pressure block 31, which makes it easier to remove and install the upper pressure block 31 during the disassembly and assembly process.

[0055] like Figure 10 , 11 In the embodiments shown in 14 and 15, the range of motion of the locking lever 33 relative to the locking device 34 is not less than the height of the blocking part 3111, so that the upper pressure block 31 can be fully raised above the supported object, substantially or completely eliminating the structural interference between the blocking part 3111 and the supported object when the upper pressure block 31 rotates.

[0056] like Figures 4 to 5 In the embodiment shown, the lower pressure block 32 has a wing plate portion 321 and a vertical plate portion 3211 on both sides, and the upper pressure block 31 has a pressing portion 311 on both sides, which can achieve the effect of a single support component 1 supporting the objects on both sides.

[0057] like Figures 6 to 7 In the embodiment shown, the lower pressure block 32 has a wing plate portion 321 and a vertical plate portion 3211 on one side, and the upper pressure block 31 has a pressing portion 311 on one side. This enables a single support component 1 to support a single-sided support object, and is suitable for the outermost side of the support system. The other side of the upper pressure block 31 is provided with an abutment portion 312. The abutment portion 312 is adapted to extend in the direction of the lower pressure block 32 and abut against the lower pressure block 32. The abutment portion 312 is adapted to keep the pressing portion 311 and the wing plate portion 321 parallel. The abutment portion 312 is used to improve the stability of the upper pressure block 31 and improve the fixing ability of the support object.

[0058] Understandably, the briquetting kit 3 comes in both single-sided and double-sided configurations, allowing users to choose the appropriate configuration based on their specific needs, thereby increasing the versatility and applicability of the components.

[0059] Understandably, for the outermost two sides of the outermost support object, the same single-sided pressure block kit 3 can be used to achieve fixation through mirror arrangement.

[0060] In some embodiments, the surface of the crimping portion 311 facing the wing plate portion 321 is provided with an anti-slip structure, such as friction ridges or friction particles, to improve the contact stability between the crimping portion 311 and the supported object and reduce the probability of relative movement between the crimping portion 311 and the supported object.

[0061] like Figures 4 to 7In the illustrated embodiment, the lower end of the locking rod 33 passes through the locking device 34 and is provided with a removable baffle 331. The baffle 331 is adapted to restrict the locking rod 33 from disengaging from the locking device 34. Since the locking rod 33 is inserted into the locking device 34 for connection, it may disengage from the locking device 34 along the original path when the locking rod 33 is operated. In order to avoid the locking rod 33 displacing too much and completely disengaging from the locking device 34 when the locking rod 33 is operated, the lower end of the locking rod 33 is inserted through the locking device 34 and exposed below the purlin 2. Then the baffle 331 is installed. The cross-section of the baffle 331 in the insertion direction is larger than the cross-section of the rod body of the locking rod 33. The baffle 331 is adapted to abut against the surface of the locking device 34 to restrict the lower end of the locking rod 33 from retracting into the locking device 34, thereby eliminating the probability that the lower end of the locking rod 33 will further disengage from the locking device 34, further realizing the anti-disengagement and anti-scattering effect of the pressure block kit 3, thereby improving the disassembly and assembly efficiency of the pressure block kit 3.

[0062] like Figures 4 to 7 In the embodiments shown in 9, 10, 11, 14 and 15, an elastic reset member 35 is sleeved on the locking rod 33 between the upper pressure block 31 and the lower pressure block 32. The elastic reset member 35 sleeved on the locking rod 33 can obtain higher operational stability. Since the lower pressure block 32 and the purlin 2 are relatively fixed under the influence of the locking rod 33, the elastic reset member 35 can only apply force to the upper pressure block 31, pushing the upper pressure block 31 away from the lower pressure block 32, thus playing the role of actively separating the upper pressure block 31 and the lower pressure block 32. The advantage of this is that during installation, a larger space can be actively formed between the upper pressure block 31 and the lower pressure block 32, which is convenient for setting up the support object. During disassembly, the upper pressure block 31 can actively detach from the support object, which is convenient for removing the support object.

[0063] In some embodiments, the elastic reset element 35 is a spring, which has a simple structure, low cost, and is easy to install.

[0064] like Figures 4 to 7 In the embodiment shown, the first mounting cavity 21 is connected to the outside at the end of the purlin 2, and the lower pressure block 32 is adapted to be inserted into the first mounting cavity 21 from the end of the purlin 2. The engagement direction of the lower pressure block 32 and the first mounting cavity 21 is the insertion direction of the locking rod 33. The purpose of this design is to use the purlin 2 as a fixed base, make full use of the existing structure of the purlin 2 to install and fix the lower pressure block 32, limit the detachment and scattering of the lower pressure block 32, and improve the stability of the pressure block kit 3 during disassembly and assembly.

[0065] like Figures 4 to 7In the embodiment shown, the second mounting cavity 22 is connected to the outside at the end of the purlin 2. The locking device 34 is adapted to be inserted into the second mounting cavity 22 from the end of the purlin 2. The locking device 34 and the second mounting cavity 22 are engaged in the same direction as the locking rod 33. The purpose of this design is to use the purlin 2 as a fixed base, make full use of the existing structure of the purlin 2 to install and fix the locking device 34, limit the detachment and fall of the locking device 34, and improve the stability of the pressure block kit 3 during disassembly and assembly.

[0066] like Figure 2 and 3 In the illustrated embodiment, the support assembly 1 includes a support column 11 and an auxiliary support rod 12. One end of the purlin 2 is hinged to the support column 11, and the auxiliary support rod 12 is adapted to be disposed between the other end of the purlin 2 and the support column 11, so that a support angle α is formed between the other end of the purlin 2 and the support column 11. It can be understood that the longer the auxiliary support rod 12 is, the more perpendicular it is to the angle between the purlin 2 and the support column 11, and the larger the support angle α is; conversely, the shorter the auxiliary support rod 12 is, the smaller the support angle α is.

[0067] Normally, one end of the purlin 2 is hinged to the upper end of the support column 11, and the lower end of the purlin 2 is adapted to rotate relative to the support column 11 to move closer to or further away from the support column 11. It can be supported and fixed by selecting an auxiliary support rod 12 of appropriate length. The pressure block kit 3 is set on the side of the purlin 2 away from the support column 11, so that the supported object can be laid on the support column 11 from above and locked by the pressure block kit 3. The triangular structure formed by the purlin 2, the support column 11 and the auxiliary support rod 12 is located below the supported object, which can provide a relatively stable support effect for the supported object.

[0068] like Figures 1 to 3 In the illustrated embodiment, a hook assembly is provided on the upper part of the support column 11. The hook assembly includes a first hook 111, a second hook 112, and a connecting rod 113. The lower part of the first hook 111 is connected to the upper part of the support column 11. The upper part of the first hook 111 and the upper part of the second hook 112 are adapted to slide along the first direction x. The connecting rod 113 is adapted to slide along the second direction y with the lower part of the first hook 111 and the lower part of the second hook 112, and restricts the sliding of the first hook 111 and the second hook 112 along the first direction x. The first hook 111, the second hook 112, and the connecting rod 113 are adapted to be fitted with a hoop to the balcony railing 4, which is convenient for disassembly and assembly and has a stable structure.

[0069] It is understood that the first hook 111 and the second hook 112 are adapted to slide relative to each other along the first direction x, thereby adapting to the width of the handrail of the balcony railing 4. The connecting rod 113 is adapted to slide relative to the first hook 111 and the second hook 112 along the second direction y, thereby adapting to the thickness of the handrail of the balcony railing 4. The combination of the first hook 111, the second hook 112 and the connecting rod 113 can adapt to handrails of different sizes of balcony railing 4, thereby achieving effective fixation.

[0070] In some embodiments, the first hook 111 and the second hook 112 may be designed as a contour-following structure according to the shape of the handrail of the balcony railing 4, so as to better fit the handrail of the balcony railing 4 and achieve more stable and effective fixation.

[0071] like Figures 1 to 3 In the illustrated embodiment, the upper part of the first hook 111 and the upper part of the second hook 112 bend and extend towards the purlin 2 (outside the balcony) and slide to connect. The purpose of this design is to ensure the relative mobility between the first hook 111 and the second hook 112, while also reducing the intrusion of the first hook 111 and the second hook 112 into the balcony space, reducing the probability of users bumping into the first hook 111 and the second hook 112 when they are on the balcony, and improving safety.

[0072] like Figure 3 In the illustrated embodiment, the upper part of the first hook 111 and / or the upper part of the second hook 112 are provided with a first strip hole 114 along the first direction x. The upper part of the first hook 111 and the upper part of the second hook 112 are connected and fastened at the first strip hole 114 by bolts. The lower part of the first hook 111 and the lower part of the second hook 112 are provided with a second strip hole 115 along the second direction y. The connecting rod 113 is adapted to be connected and fastened at the second strip hole 115 by bolts. Loosening the bolts can realize relative movement.

[0073] like Figure 2 and 3 In the illustrated embodiment, a detachable U-shaped ring 116 is provided at the lower part of the support column 11. The U-shaped ring 116 is adapted to cooperate with the support column 11 to clamp onto the balcony railing 4. The U-shaped ring 116 and the support column 11 are preferably connected by bolts, which is convenient for disassembly and assembly. The clamping plane formed by the cooperation of the U-shaped ring 116 and the support column 11 can be set according to the specific structure of the balcony railing 4. If the clamping reaches the horizontal bar of the balcony railing 4, the clamping plane formed by the cooperation of the U-shaped ring 116 and the support column 11 is perpendicular to the horizontal plane. If the clamping reaches the vertical bar of the balcony railing 4, the clamping plane formed by the cooperation of the U-shaped ring 116 and the support column 11 is parallel to the horizontal plane.

[0074] One or more embodiments of this application disclose a support system, with reference to... Figure 1 and Figure 2 The system includes multiple balcony supports according to any of the above embodiments. The balcony supports are arranged at intervals along the balcony railing 4, and the interval size can be set according to the width of the supported object. One or more single-sided structure (including wing plate part 321, pressing part 311 and upright plate part 3211) pressure block kits 3 are provided on the outermost (left and right sides) balcony supports, and one or more double-sided structure (including wing plate part 321, pressing part 311 and upright plate part 3211) pressure block kits 3 are provided on the middle balcony supports. Adjacent supported objects can be installed by sharing a balcony support through the double-sided structure pressure block kits 3, thereby reducing the number of balcony supports, improving installation efficiency, reducing material usage, and reducing costs.

[0075] The relationship between the number of balcony supports and the number of supported objects is as follows: the number of balcony supports is equal to the number of supported objects plus 1. Among them, the number of balcony supports with pressure block kits with wing plates on both sides is the number of supported objects minus 1, and the number of balcony supports with pressure block kits with wing plates on one side is 2.

[0076] One or more embodiments of this application disclose a photovoltaic system, with reference to... Figure 1 and Figure 2 The photovoltaic module 5, as described in the above embodiments, is laid on the support system as a support object of the support system. The clamping block kit 3 is adapted to cooperate in clamping the frame of the photovoltaic module 5, thereby fixing the photovoltaic module 5.

[0077] It is worth noting that the support system of this application includes, but is not limited to, the use of laying photovoltaic modules 5 to form a photovoltaic system. In fact, users can also use common items that need to be hung on the outside of the balcony as support objects for the support system, including panel components (glass panels, rain shields), special components (clothes racks, clothes rods), etc., to form new systems. This application does not provide detailed examples of such new systems.
