DETAILED DESCRIPTION

[0060] The following will be combined with the attached embodiment of the present utility model Figure 1-14 , the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making novel efforts are within the scope of protection of the utility model.

[0061] In the description of the present invention, it should be understood that the terms "upper" and "lower" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the positions or elements referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limitations of the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0062] Combination Figure 1-Figure 14 As shown, the utility model provides a photovoltaic bracket 100 to facilitate the transportation and storage of the photovoltaic bracket 100 .

[0063] like Figure 3 As shown, the photovoltaic support 100 includes a bottom support structure 101 , a top support structure 102 and an oblique support 103 , wherein the bottom support structure 101 is supported on the ground, etc., to provide a supporting foundation for the top support structure 102 and the oblique support 103 .

[0064] The bottom support structure 101 is foldable. It should be noted that the structure and shape of the bottom support structure 101 are not limited, and it can be formed by at least two support members that are rotatably connected, and can be folded or unfolded into an X shape, a Y shape, or a V shape, etc. by rotation. When the bottom support structure 101 is in use, the bottom support structure 101 is unfolded to support the ground or other supporting members such as a balcony bracket; when the bottom support structure 101 needs to be stored, the bottom support structure 101 is folded together for storage.

[0065] The top support structure 102 is foldable. It should be noted that the structure and shape of the top support structure 102 are not limited and can be similar to the structure of the bottom support structure 102, that is, it is also formed by at least two support members that can be rotatably connected and can be folded or unfolded into an X shape, a Y shape, or a V shape by rotation; it can also be set to other shapes, for example, a structure similar to a folding fan frame. When the top support structure 102 is used, Figure 1 and Figure 2As shown, the top support structure 102 is unfolded and tilted, so that the bottom end of the top support structure 102 can be tilted and supported on the bottom support structure 101, thereby improving the stability of the top support structure 102, and installing the photovoltaic component 200 on the unfolded top support structure 102; when the top support structure 102 needs to be stored, the photovoltaic component 200 is removed and the top support structure 102 is folded together for storage.

[0066] The bottom end of the diagonal brace 103 is foldably connected to the bottom support structure 101, and the top end is foldably connected to the top support structure 102, and the diagonal brace 103 is used to support the side of the top support structure 102 away from the photovoltaic module 200. The diagonal brace 103 is used to support the top support structure 102 to improve the stability of the top support structure 102. When the photovoltaic bracket 100 is not in use and needs to be stored, the connection between the bottom support structure 101 and the bottom end of the top support structure 102 is opened, and then the bottom support structure 101 and the top support structure 102 are respectively rotated between the diagonal brace 103 to achieve folding; or, the connection between the top end of the diagonal brace 103 and the top support structure 102 is opened, and then the bottom support structure 101 is respectively rotated between the top support structure 102 and the diagonal brace 103 to achieve folding, or, the connection between the bottom end of the diagonal brace 103 and the bottom support structure 101 is opened, and then the top support structure 102 is respectively rotated between the bottom support structure 101 and the diagonal brace 103 to achieve folding, so that the photovoltaic bracket 100 is completely stored together. The specific storage process is as follows: Figure 4 and Figure 5 shown.

[0067] In one embodiment of the present invention, the top support structure 102 includes at least two rotatably connected support members, and the support members are rod-shaped or plate-shaped structures. It can be understood that the rotatable connection between adjacent support members can be a rotatable connection between the ends of the adjacent support members; it can also be a rotatable connection between the middle parts of the adjacent support members, such as Figure 6 It can also be that the end of one of the adjacent supports is rotatably connected to the middle portion of the other, such as Fig.14 It should be noted that the middle part of the support member includes but is not limited to the center position of the support member.

[0068] In order to improve the versatility of the photovoltaic bracket 100, an embodiment of the utility model discloses that at least one of the adjacent support members that are rotatably connected is retractable, so as to facilitate adjusting the length of the support member, thereby realizing the installation of different photovoltaic modules 200. Specifically, the support member can be an electric push rod or the like to achieve retractability, or a cylinder or other retractable member.

[0069] In one embodiment of the present invention, the photovoltaic support 100 further includes a fixing component, which is disposed on the top supporting structure 102 and is used to fix the photovoltaic component 200. The setting of the fixing component improves the stability of the photovoltaic component 200 placed on the top supporting structure 102.

[0070] Specifically, an embodiment of the utility model discloses that the fixing assembly includes at least 3 fixing members, and at least 3 fixing members are arranged in a triangular or quadrilateral shape to stably limit the photovoltaic assembly 200. The fixing members in the fixing assembly are not limited to being arranged in a triangle or quadrilateral shape, and can also be arranged in other shapes, such as a pentagon.

[0071] Take the top support structure 102 including two support members as an example. Figure 6 As shown, for the convenience of description, the two support members are named as the first support member 102-1 and the second support member 102-2 respectively. The first support member 102-1 and the second support member 102-2 cross at the midpoint of their respective length directions to form an X-shaped structure, and are rotatably connected at the intersection of the two, thereby improving the stability of the top support structure 102 when rotating, folding or unfolding. It should be noted that the cross-connection of the first support member 102-1 and the second support member 102-2 disclosed above to form an X-shaped structure is only a specific embodiment of the present utility model. In actual applications, the ends of the first support member 102-1 and the second support member 102-2 can also be rotatably connected to form a V-shape, etc.

[0072] Take the example of a fixing assembly including 4 fixing parts, such as Figure 6 As shown, two fixing members are distributed on the first support member, and two fixing members are distributed on the second support member 102-2. For the convenience of description, the fixing members installed at the top of the first support member 102-1 and the top of the second support member 102-2 are named as top clamping members 102-3, and the fixing members installed at the bottom of the first support member 102-1 and the bottom of the second support member 102-2 are named as bottom clamping members 102-4. The top clamping member 102-3 is used to clamp the top of the photovoltaic component 200, and the bottom clamping member 102-4 is used to clamp the bottom of the photovoltaic component 200. By adjusting the angle between the first support member 102-1 and the second support member 102-2, photovoltaic components 200 of different specifications and sizes can be clamped, thereby improving the versatility of the photovoltaic component 200.

[0073] It can be understood that the above-disclosed four fixing members in a quadrilateral distribution are only a specific embodiment of the present utility model. In actual applications, a fixing assembly can also be provided including three fixing members, wherein one fixing member is installed at the top of the first support member 102-1 or the second support member 102-2, and one of the other two fixing members is installed at the bottom end of the first support member 102-1, and the other is installed at the bottom end of the second support member 102-2, that is, the three fixing members can form a triangular arrangement to limit the photovoltaic assembly 200. In actual applications, in order to improve the fixing strength, the number of the bottom ends of the first support member 102-1 is the same as the number of the ends of the bottom clamping members 102-4 facing the photovoltaic panel. Of course, the number of the bottom ends of the first support member 102-1 can be greater or less than the number of the ends of the bottom clamping members 102-4 facing the photovoltaic panel according to actual needs.

[0074] It should be noted that the top of the first support member 102-1 is not limited to the top of the first support member 102-1, and the bottom of the first support member 102-1 is not limited to the bottom of the first support member 102-1. Instead, it is defined relative to two fixing members installed on the first support member 102-1, one fixing member is located above the other fixing member, so the fixing member that is closer to the top is installed at the top of the first support member 102-1, and the fixing member that is closer to the bottom is installed at the bottom of the second support member 102-2. In other words, the top of the first support member 102-1 does not specifically refer to the top of the first support member 102-1, and the bottom of the first support member 102-1 does not specifically refer to the bottom of the first support member 102-1. Similarly, the top of the second support member 102-2 does not specifically refer to the top of the second support member 102-2, and the bottom of the second support member 102-2 does not specifically refer to the bottom of the second support member 102-2. Similarly, the top of the photovoltaic component 200 is not limited to the uppermost part of the photovoltaic component, and the bottom of the photovoltaic component 200 is not limited to the lowermost part of the photovoltaic component 200, but is only a relative upper and lower limitation of two positions of the photovoltaic component 200.

[0075] In order to facilitate the disassembly of the top clamping member 102-3 and the bottom clamping member 102-4, an embodiment of the utility model discloses that the top clamping member 102-3 on the first support member 102-1 is detachably mounted on the first support member 102-1 by means of fasteners such as screws, and the bottom clamping member 102-4 on the first support member 102-1 is detachably mounted on the first support member 102-1 by means of fasteners such as screws; similarly, the top clamping member 102-3 on the second support member 102-2 can be detachably mounted on the second support member 102-2 by means of fasteners such as screws, and the bottom clamping member 102-4 on the second support member 102-2 can be detachably mounted on the second support member 102-2 by means of fasteners such as screws. That is, the fixing member and the support member are detachably connected by means of fasteners such as screws.

[0076] In order to facilitate the adjustment of the spacing between the top clamping member 102-3 and the bottom clamping member 102-4 on the first support member 102-1, a plurality of fastening holes may be arranged at intervals along the length direction of the first support member 102-1, and the distance between the top clamping member 102-3 and the bottom clamping member 102-4 may be adjusted by fixing the top clamping member 102-3 and the bottom clamping member 102-4 on different fastening holes to adapt to photovoltaic modules 200 of different specifications. Similarly, a plurality of fastening holes may be arranged at intervals along the length direction of the second support member 102-2, and the distance between the top clamping member 102-3 and the bottom clamping member 102-4 may be adjusted by fixing the top clamping member 102-3 and the bottom clamping member 102-4 on different fastening holes to adapt to photovoltaic modules 200 of different specifications, thereby further improving the versatility of the photovoltaic bracket 100.

[0077] It should be noted that the above-disclosed fixing assembly including at least three fixings is only a specific embodiment of the present invention. The fixing assembly is not limited to including fixings for clamping the photovoltaic assembly, and may also be other structures. For example, in one embodiment of the present invention, the fixing assembly alone or also includes at least two hanging grooves, at least one hanging groove is arranged above at least another hanging groove, and the two are arranged oppositely to limit the two ends of the photovoltaic assembly 200. For example, the fixing assembly includes at least three fixings and also includes four hanging grooves, which are respectively named as the first hanging groove 102-1d, the second hanging groove 102-1e, the third hanging groove 102-2d and the fourth hanging groove 102-2e. The first hanging groove 102-1d and the second hanging groove 102-1e are respectively arranged on the first support member 102-1, wherein the groove top of the first hanging groove 102-1d is arranged toward the top clamping member 102-3 on the first support member 102-1, and the first hanging groove 102-1d is used to hang the edge of the top frame of the photovoltaic module 200; the groove top of the second hanging groove 102-1e is arranged toward the bottom clamping member 102-4 on the first support member 102-1, and the second hanging groove 102-1e is used to hang the edge of the bottom frame of the photovoltaic module 200. The arrangement of the first hanging groove 102-1d and the second hanging groove 102-1e can realize the installation of the photovoltaic module 200, and the top clamping member 102-3 and the bottom clamping member 102-4 can clamp the photovoltaic module 200 by rotating the first support member 102-1 to adjust the inclination angle of the first support member 102-1.

[0078] Similarly, the third hanging groove 102-2d and the fourth hanging groove 102-2e can be respectively arranged on the second support member 102-2, wherein the groove top of the third hanging groove 102-2d is arranged facing the top clamping member 102-3 on the second support member 102-2, and the third hanging groove 102-2d is used to hang the edge of the top frame of the photovoltaic component 200; the groove top of the fourth hanging groove 102-2e is arranged facing the bottom clamping member 102-4 on the second support member 102-2, and the fourth hanging groove 102-2e is used to hang the edge of the bottom frame of the photovoltaic component 200. The third hanging groove 102-2d and the fourth hanging groove 102-2e can realize the preliminary installation of the photovoltaic component 200. By rotating the second support member 102-2, the inclination angle of the second support member 102-2 is adjusted to realize the top clamping member 102-3 and the bottom clamping member 102-4 clamping the photovoltaic component 200.

[0079] It can be understood that when the photovoltaic component 200 to be installed does not need to be clamped by the top clamp 102-3 and the bottom clamp 102-4, the top clamp 102-3 and the bottom clamp 102-4 can be removed, and only the hanging groove is used to limit the photovoltaic component 200, thereby further improving the versatility of the photovoltaic bracket 100.

[0080] In one embodiment of the utility model, the photovoltaic support 100 further includes a rotation locking member, wherein the rotation locking member is used for rotation and locking between at least two rotatably connected support members. The provision of the rotation locking member improves the stability of the top support structure 102 and the bottom support structure 101 when they are unfolded.

[0081] In one embodiment of the utility model, the rotation locking member includes a connecting shaft 102-5, and one of the adjacent supporting members that can be rotatably connected is fixed to the connecting shaft 102-5, and the other is provided with a hinge hole. A one-way ratchet is provided in the hinge hole, and a reverse pawl that is unidirectionally meshed with the one-way ratchet is provided on the connecting shaft 102-5. The one-way ratchet and the reverse pawl cooperate to enable the adjacent supporting members to maintain any tilt angle value, and also facilitate the adjustment of the angle between the adjacent supporting members.

[0082] It should be noted that the locking method of adjacent support members disclosed above is only a specific implementation of the present invention. In practical applications, other locking methods can also be set, for example, Figure 6As shown, among the adjacent supporting members that can be rotatably connected, one is provided with a first rotating connecting hole 102-1a, and a first one-way ratchet 102-1b is arranged in the first rotating connecting hole 102-1a, and the other is provided with a second rotating connecting hole 102-2a; a second one-way ratchet 102-2b is arranged in the second rotating connecting hole 102-2a, and the second one-way ratchet 102-2b is in the opposite direction to the first one-way ratchet 102-1b; at least one first reverse pawl 102-5a and at least one second reverse pawl 102-5b are respectively arranged on the connecting shaft 102-5, the first reverse pawl 102-5a is engaged in one-way meshing transmission with the first one-way ratchet 102-1b, and the second reverse pawl 102-5b is engaged in one-way meshing transmission with the second one-way ratchet 102-2b. That is to say, the cooperation between the first one-way ratchet 102-1b and the first reverse pawl realizes the unidirectional movement of the first support member 102-1, and the first reverse pawl 102-5a locks the first one-way ratchet 102-1b to realize the reverse locking of the first support member 102-1; at the same time, the cooperation between the second one-way ratchet 102-2b and the second reverse pawl 102-5b realizes the unidirectional movement of the second support member 102-2, and the second reverse pawl 102-5b locks the second one-way ratchet 102-2b to realize the reverse locking of the second support member 102-2.

[0083] Specifically, a half-circle first one-way ratchet 102-1b can be set in the first rotating connection hole 102-1a, and a half-circle second one-way ratchet 102-2b can be set in the second rotating connection hole 102-2a. It should be noted that the first one-way ratchet 102-1b and the second one-way ratchet 102-2b are not limited to half a circle, and are specifically set according to the angle range required for the first support member 102-1 and the second support member 102-2 to rotate.

[0084] like Figure 6 As shown, taking the adjacent support members that can be rotatably connected as the first support member 102-1 and the second support member 102-2 as an example, the first support member 102-1 is provided with a first rotating connection hole 102-1a, and the second support member 102-2 is provided with a second rotating connection hole 102-2a, and the connecting shaft 102-5 passes through the first rotating connection hole 102-1a and the second rotating connection hole 102-2a to realize the rotatable connection between the first support member 102-1 and the second support member 102-2.

[0085] In order to ensure that the first support member 102-1 and the second support member 102-2 can remain stationary when they are rotated to a certain angle, the first support member 102-1 and the second support member 102-2 are locked by the connecting shaft 102-5 to achieve stable clamping of the photovoltaic component 200. In addition, after the photovoltaic component 200 is installed on the top support structure 102, the photovoltaic component 200 interacts with the fixing member on the top support structure 102, avoiding the ends of the first support member 102-1 and the second support member 102-2 from being relatively close, further improving the stability of the photovoltaic bracket 100.

[0086] It should be noted that the above-disclosed method of locking the first support member 102-1 and the second support member 102-2 by cooperating between a ratchet and a pawl is only a specific implementation method of the present utility model. In actual applications, locking can also be achieved by other methods. For example, an external thread is provided on the connecting shaft 102-5, and an internal thread is provided in the first rotating connecting hole 102-1a, which is threadedly connected to the external thread on the connecting shaft 102-5. That is, the first support member 102-1 is threadedly connected to the connecting shaft 102-5, and the second support member 102-2 is pressed against the first support member 102-1 by tightening the nut on the connecting shaft 102-5 to achieve locking of the first support member 102-1 and the second support member 102-2.

[0087] It should also be noted that the locking in this article means that after the adjacent support members are rotated to the set position, the connecting shaft 102-5 interacts with the support members, thereby limiting and fixing the positions of the adjacent support members.

[0088] In one embodiment of the utility model, among the adjacent support members that can be rotatably connected, one is provided with a first rotation groove 102-1c, and the other is provided with a second rotation groove 102-2c. The second rotation groove 102-2c is buckled at the first rotation groove 102-1c to limit the relative rotation angle between the adjacent support members, thereby avoiding the problem of excessively large unfolding angles between the adjacent support members and facilitating the adjacent support members to be stored together.

[0089] Taking the adjacent supporting members that can be rotatably connected as the first supporting member 102-1 and the second supporting member 102-2 as an example, the first supporting member 102-1 is provided with a first rotation groove 102-1c, and the second supporting member 102-2 is provided with a second rotation groove 102-2c. The second rotation groove 102-2c of the first supporting member 102-1 is buckled at the first rotation groove 102-1c to limit the relative rotation angle between the first supporting member 102-1 and the second supporting member 102-2. Figure 6When the relative rotation angle between the first support member 102-1 and the second support member 102-2 reaches a certain value, the side wall of the first support member 102-1 abuts against the side wall of the second rotation groove 102-2c, and similarly, the side wall of the second support member 102-2 abuts against the side wall of the first rotation groove 102-1c, thereby avoiding the problem of too large an expansion angle between the first support member 102-1 and the second support member 102-2.

[0090] In order to ensure the flatness of folding and storing adjacent rotatably connected supporting members, an embodiment of the utility model discloses that the end faces of the adjacent rotatably connected supporting members facing each other are arranged flush, and the end faces facing away from each other are also arranged flush.

[0091] by Figure 6 In the embodiment, the adjacent supporting members that can be rotatably connected are respectively the first supporting member 102-1 and the second supporting member 102-2. For example, the first supporting member 102-1 and the second supporting member 102-2 are arranged flush with the surface perpendicular to the connecting shaft 102-5.

[0092] In another embodiment of the present invention, the top support structure 102 includes three support members, such as Fig.14 As shown, for the convenience of description, the two support members are named as the first support member 102-1, the second support member 102-2 and the third support member 102-6, wherein the end of the first support member 102-1 and the end of the second support member 102-2 are rotatably connected to the center of the third support member 102-6, respectively, to form an X shape. The second support member 102-2 can be used as a fixed member, and the first support member 102-1 and the second support member 102-2 can be rotated as rotating members, so as to quickly adjust the tilt angle of the first support member 102-1 and the second support member 102-2 with reference to the third support member 102-6.

[0093] It can be understood that the above-mentioned arrangement of the three support members is only a specific implementation of the present invention. In actual applications, other arrangements can also be set. For example, the ends of the first support member 102-1, the second support member 102-2 and the third support member 102-6 can be rotatably connected respectively.

[0094] In one embodiment of the present utility model, Figure 8 , Fig. 9 and Fig.13 As shown, the bottom support structure 101 includes at least two rotatably connected support members. Specifically, the bottom support structure 101 can be similar to the structure of the top support structure 102 in any of the above embodiments, and of course, can also be set to a different structure, which can be selected according to needs.

[0095] For the convenience of description, the support member in the bottom support structure 101 is named as the bottom support member 101-1. That is, the bottom support structure 101 includes at least two bottom support members 101-1, each of which is rotatably connected, and the bottom support member 101-1 can be rotated and unfolded to support the bottom end of the top support structure 102. When the photovoltaic bracket 100 is needed to support the photovoltaic assembly 200, each bottom support member 101-1 in the bottom support structure 101 is rotated to unfold to stably support it on the ground, etc., to provide a stable support foundation for the top support structure 102 and the diagonal support 103. It should be noted that the rotatable connection between adjacent bottom support members 101-1 can be a rotatable connection between the ends of adjacent bottom support members 101-1; it can also be a rotatable connection between the middle parts of adjacent bottom support members 101-1; it can also be a rotatable connection between the ends of one of the adjacent bottom support members 101-1 and the middle parts of the other, and as long as the method of realizing the foldability of the bottom support structure 101 is met, it belongs to the protection scope of the present utility model. It should be noted that the middle portion of the bottom support member 101 - 1 includes but is not limited to the center position of the bottom support member 101 - 1 .

[0096] In order to improve the versatility of the photovoltaic bracket 100, an embodiment of the utility model discloses that at least one of the adjacent bottom support members 101-1 that are rotatably connected is retractable, so as to facilitate adjusting the length of the bottom support member 101-1, thereby achieving installation of different photovoltaic modules. Specifically, the bottom support member 101-1 can be an electric push rod or the like to achieve retraction, or a cylinder or other retractable member.

[0097] In order to improve the stability of the bottom support structure 101 when it is unfolded, an embodiment of the utility model discloses that each bottom support member 101-1 also realizes relative rotation and locking through a rotating locking member. The rotating locking member includes a connecting shaft 102-5, and the connecting shaft 102-5 is locked in the same manner as the bottom support member 101-1, and also realizes one-way transmission and locking through the cooperation of a one-way ratchet and a reverse pawl. For details, please refer to the embodiment of the connection between the top support structure 102 and the connecting shaft 102-5, which will not be repeated here.

[0098] In one embodiment of the present invention, the number of the bottom support members 101-1 is at least 3, wherein at least one bottom support member 101-1 is used as a fixed support member 101-2, and at least two bottom support members 101-1 are used as movable support members 101-3. Figure 8 and Fig. 9As shown. One end of the fixed support member 101-2 is rotatably connected to one end of each movable support member 101-3, and can be arranged in a Y shape or an X shape with each movable support member 101-3. Of course, the bottom support structure 101 can also be arranged to include more than three bottom support members 101-1, and the ends of the multiple bottom support members 101-1 can be rotatably connected to form a radial structure.

[0099] At least two bottom support members 101-1 are used to support the bottom end of the top support structure 102 to improve the stability of the top support structure 102. When the bottom support structure 101 is unfolded, the fixed support member 101-2 can remain stationary, and only the movable support member 101-3 is rotated, so that the movable support member 101-3 is rotated in a direction relatively away from the fixed support member 101-2, so that the fixed support member 101-2 and the movable support member 101-3 form a stable support base; when the bottom support structure 101 needs to be stored, the movable support member 101-3 is rotated in a direction relatively close to the fixed support member 101-2, so that the fixed support member 101-2 and the movable support member 101-3 are closed and folded together, which facilitates the storage of the bottom support structure 101.

[0100] In another embodiment of the present utility model, Fig.13 As shown, at least two bottom support members 101-1 are rotatably connected, and the ends of at least two bottom support members 101-1 are rotatably connected to form a V shape. Of course, at least two bottom support members 101-1 can also be cross-arranged to form an X shape. The bottom support member 101-1 is used to support the bottom end of the top support structure 102. It should be noted that the bottom support structure 101 and Fig.13 The top supporting structure 102 in the embodiment is similar, and the unfolding and folding methods are the same. For details, please refer to the top supporting structure 102, which will not be repeated here.

[0101] In one embodiment of the utility model, one of the two rotatably connected bottom support members 101-1 is provided with a first rotation notch, and the other is provided with a second rotation notch, and the second rotation notch is buckled at the first rotation notch to limit the relative rotation angle of the two. When the relative rotation angle of the two bottom support members 101-1 reaches a certain value, the side wall of one bottom support member 101-1 abuts against the side wall of the second rotation notch to limit the position, and similarly, the side wall of the other bottom support member 101-1 abuts against the side wall of the first rotation notch to limit the position, thereby avoiding the problem of too large an expansion angle between the two bottom support members 101-1.

[0102] In order to ensure the flatness of the two bottom support members 101 - 1 when folded and stored, an embodiment of the utility model discloses that the end faces of the two rotatably connected bottom support members 101 - 1 are arranged flush with each other, and the end faces facing away from each other are also arranged flush with each other.

[0103] In order to achieve stable support for the top support structure 102, an embodiment of the utility model discloses that a limiting groove 101-1a is provided on the bottom support structure 101, such as Figure 8 , Fig. 9 , Fig.11 and Fig.13 The limiting groove 101 - 1 a is used to accommodate and support the bottom end of the top supporting structure 102 .

[0104] Specifically, the limiting groove 101-1a is provided on the bottom support member 101-1. Figure 8 and Fig. 9 As shown, the limiting groove 101 - 1 a is provided on the movable support member 101 - 3 .

[0105] In order to facilitate the adjustment of different tilt angles of the photovoltaic assembly 200, an embodiment of the present utility model discloses that there are multiple limiting grooves 101-1a, which are arranged at intervals along the length direction of the bottom support member 101-1. Fig.10 Three states of the photovoltaic support 100 corresponding to different tilt angles of the photovoltaic assembly 200 are shown.

[0106] In order to facilitate the user to adjust the tilt of the photovoltaic component 200 to a desired angle, an embodiment of the utility model discloses that a component angle mark 101-1b is provided on the bottom support member 101-1, and the component angle mark 101-1b is used to display the tilt angle of the photovoltaic component 200 when the bottom support structure 101 is supported in the corresponding limiting groove 101-1a.

[0107] It should be noted that the number of component angle marks 101-1b is at least 1. When the number of component angle marks 101-1b is 1, the component angle mark 101-1b can be set at the position of the limiting groove 101-1a corresponding to one end along the length direction of the bottom support member 101-1, and the limiting grooves 101-1a are set at equal angles. It should be noted that the equal angle spacing means that when the photovoltaic components are respectively limited in each limiting groove 101-1a along the length direction of the bottom support member 101-1, the difference in the inclination angle is equal. Of course, the limiting grooves 101-1a can also be set at unequal angles. It should also be noted that the number of component angle marks 101-1b can also be set to at least 2, and the component angle marks 101-1b can be set at least at the position of the limiting grooves 101-1a corresponding to the two ends along the length direction of the bottom support member 101-1.

[0108] In this embodiment, the number of component angle marks 101-1b is equal to the number of limiting grooves 101-1a, and they are arranged in a one-to-one correspondence as an example. Fig.11As shown, the component angle mark 101-1b is set on the side of the bottom support member 101-1, which is convenient for the operator to check and realize rapid adjustment to the desired tilt angle.

[0109] In order to improve the anti-skid performance of the bottom support structure 101, an embodiment of the present utility model discloses that an anti-skid pad 101-4 is provided at the bottom end of the bottom support structure 101. Fig.12 Of course, an anti-skid layer or the like may also be provided at the bottom end of the bottom support structure 101 .

[0110] In one embodiment of the utility model, along the length direction of the bottom support member 101-1, the bottom support member 101-1 is an integrated structure. It can be understood that the above-disclosed bottom support member 101-1 as an integrated structure is only a specific embodiment of the utility model. In practical applications, it can also be set as follows: along the length direction of the bottom support member 101-1, the bottom support member 101-1 includes a plurality of bottom sub-supports that are rotatably connected end to end in sequence, so as to facilitate the adjustment of the length of the bottom support member 101-1 to adapt to different floor space requirements. It should be noted that the adjacent bottom sub-supports can be locked at a certain angle by cooperating with a one-way ratchet and a reverse pawl, or can be locked by other structures.

[0111] In one embodiment of the utility model, the photovoltaic support 100 further includes a locking structure, which is arranged on the bottom support structure 101 and is used to lock the bottom end of the top support structure 102 to the bottom support structure 101. The setting of the locking structure improves the stability of the photovoltaic support 100 when it is unfolded, and avoids the problem of the photovoltaic support 100 closing and the photovoltaic assembly 200 overturning due to the failure of the ratchet pawl.

[0112] Specifically, the locking structure can be a strap that binds the bottom end of the top support structure 102 to the bottom support structure 101, or the locking structure can be a hook set on the bottom support structure 101. Correspondingly, the bottom end of the top support structure 102 is provided with a slot that engages with the hook.

[0113] In one embodiment of the utility model, the top end of the diagonal brace 103 is rotatably connected to the top support structure 102, and the bottom end of the diagonal brace 103 is rotatably connected to the bottom support structure 101. In other words, the diagonal brace 103 is folded with the top support structure 102 by being rotatably connected to the top support structure 102. Similarly, the diagonal brace 103 is folded with the bottom support structure 101 by being rotatably connected to the bottom support structure 101. It should be noted that the diagonal brace 103 is not limited to being rotatably connected to the connecting shaft of the bottom support structure 101. The diagonal brace 103 can also be connected to the bottom support member 101-1, etc.; the diagonal brace 103 is not limited to being rotatably connected to the connecting shaft of the top support structure 102. The diagonal brace 103 can also be connected to the support member of the top support structure 102, etc.

[0114] The bottom end of the diagonal brace 103 can be rotatably connected to the connecting shaft 102-5 on the bottom supporting structure 101, that is, the diagonal brace 103 is connected to the rotation and expansion axis of the bottom supporting structure 101, which reduces the force of the diagonal brace 103 on the bottom supporting structure 101, causing the bottom supporting structure 101 to be incorrectly expanded or stored.

[0115] The top end of the diagonal brace 103 can be rotatably connected to the connecting shaft 102-5 on the top supporting structure 102, that is, the diagonal brace 103 is connected to the rotation and deployment axis of the top supporting structure 102, which reduces the force of the diagonal brace 103 on the top supporting structure 102, causing the top supporting structure 102 to be accidentally deployed or stored.

[0116] It should be noted that the diagonal brace 103 is not limited to being connected to the connecting shaft 102-5 on the bottom supporting structure 101, and the diagonal brace 103 can also be rotatably connected to each support member on the bottom supporting structure 101. Similarly, the diagonal brace 103 is not limited to being connected to the connecting shaft 102-5 on the top supporting structure 102, and the diagonal brace 103 can also be rotatably connected to each support member on the top supporting structure 102.

[0117] Specifically, the diagonal brace 103 can be set to include two support plates 103-3, and the first rotating shaft 103-4 is clamped on the inner side of the top end of the support plate 103-3, and the first rib 102-5c is provided at one end of the connecting shaft 102-5 connected to the top supporting structure 102, and the first rib 102-5c is placed between the two support plates 103-3, and the first rib 102-5c is provided with a through hole allowing the first rotating shaft 103-4 to pass through, that is, it can be rotatably connected through the first rotating shaft 103-4, wherein the axis centerline of the first rotating shaft 103-4 is perpendicular to the axis centerline of the connecting shaft 102-5 on the top supporting structure 102. A second rib 101-5 is provided at the top of the bottom support structure 101, and the other ends of the two support plates 103-3 are clamped on both sides of the second rib 101-5 and are rotatably connected via a second rotation axis 103-2, wherein the axis of the second rotation axis 103-2 is arranged parallel to the axis of the first rotation axis 103-4. In this embodiment, the diagonal brace 103 is rotatably connected to the top support structure 102 and the bottom support structure 101 by providing two support plates 103-3, so as to facilitate the installation and disassembly of the diagonal brace 103.

[0118] In order to reduce the weight of the diagonal brace 103, weight-reducing holes can be opened on the two support plates 103-3, such as Figure 8 and Fig. 9 shown.

[0119] It should be noted that the top end of the diagonal brace 103 disclosed above is rotatably connected to the top support structure 102, and the bottom end is rotatably connected to the bottom support structure 101, so as to realize the foldable connection between the diagonal brace 103 and the top support structure, i.e., the bottom support structure 101, which is only a specific embodiment of the present invention. In practical applications, it can also be set to other foldable connection methods, for example, the top end of the diagonal brace 103 is slidably connected to the top support structure 102, and the bottom end of the diagonal brace 103 is rotatably connected to the bottom support structure 101. The slidable connection between the top end of the diagonal brace 103 and the top support structure 102 can be: a first slide rail is provided on one of the top end of the diagonal brace 103 and the top support structure 102, and a first slider slidably connected to the first slide rail is provided on the other, and the first slider can be locked in the first slide rail. A plurality of first locking holes spaced apart along the length direction of the first slide rail can be opened on the first slide rail, the first fastener is threadedly connected to the first locking hole, and the first fastener passes through the first locking hole and can abut against the first slider to lock the first slider, thereby locking the diagonal brace and the top support structure.

[0120] Of course, similarly, the top end of the diagonal brace 103 can be rotatably connected to the top support structure 102, and the bottom end of the diagonal brace 103 can be slidably connected to the bottom support structure 101. Specifically, a second slide rail 101-6 is provided on one of the bottom end of the diagonal brace 103 and the bottom support structure 101, and a second slider slidably connected to the second slide rail 101-6 is provided on the other, and the second slider can be locked in the second slide rail 101-6. The slidable connection between the bottom end of the diagonal brace 103 and the bottom support structure 101 can be: Fig.13 As shown, taking the example of a second slide rail 101-6 being provided on the bottom supporting structure 101 and the bottom end of the diagonal brace 103 being connected to the second slider, a plurality of second locking holes spaced apart along the length direction of the second slide rail 101-6 can be opened on the second slide rail 101-6, the second fastener is threadedly connected to the second locking hole, and the second fastener passes through the second locking hole and can abut against the second slider to lock the second slider, thereby locking the diagonal brace and the top supporting structure 102.

[0121] In one embodiment of the utility model, the diagonal brace 103 is an integrated structure along the length direction of the diagonal brace 103. It can be understood that the number of the diagonal braces 103 along the thickness direction of the diagonal brace 103 can be 2 or more. Of course, the diagonal brace 103 can also be 1 along the thickness direction and the width direction.

[0122] It should also be noted that the diagonal brace 103 is not limited to the above structure, and the diagonal brace 103 may also be set to other structures. For example, the diagonal brace 103 includes at least two sub-diagonal braces 103-1 that are rotatably connected end to end along the length direction of the diagonal brace 103. Fig.13 shown.

[0123] Of course, the diagonal brace 103 may also be arranged to be a retractable structure along the length direction of the diagonal brace 103 to adapt to the scenarios where the diagonal brace 103 has different length requirements.

[0124] The photovoltaic bracket 100 provided by the utility model has the following advantages:

[0125] (1) Both the top support structure 102 and the bottom support structure 101 can be freely unfolded and stored. When folded and stored, the space is small and convenient for transportation. When in use, they can be directly pulled and unfolded, eliminating other installation steps. The installation is convenient and quick, which improves the consumer's experience.

[0126] (2) The top support structure 102 and the bottom support structure 101 can be locked when unfolded by means of ratchet pawls, which can realize unfolding and folding on the one hand, and prevent accidental folding from causing the assembly to overturn on the other hand, thereby increasing the safety of the photovoltaic bracket 100;

[0127] (3) The provision of at least two limiting grooves 101 - 1 a enables the photovoltaic module 200 to be adjusted to different tilt angles.

[0128] (4) The setting of the locking structure further improves the supporting stability of the bottom supporting structure 101 on the top supporting structure 102.

[0130] Since the power generation device 1000 provided by the present invention includes the photovoltaic bracket 100 in any one of the above embodiments, the beneficial effects of the above photovoltaic bracket 100 are all included in the power generation device 1000 disclosed in the present invention.
