Description

Technical Field

[0001] This application belongs to the field of equipment installation technology, specifically relating to an adjustable support and a photovoltaic power generation device. Background Technology

[0002] Photovoltaic power generation is a type of new energy source, and photovoltaic panels are typically installed outdoors to obtain sufficient sunlight. During the installation process, the photovoltaic panels need to be mounted on brackets to protect them and improve their utilization rate.

[0003] In practical applications, the support system includes a load-bearing support and an adjusting support. The load-bearing support is mainly used to support the photovoltaic panels, while the adjusting support is mainly used to adjust the angle of the photovoltaic panels. Usually, the rotating shaft of the adjusting support adopts the method of pressing the spring to form a rotational damping force around the spring. However, this damping force cannot be adjusted, and the damping force cannot be changed, which causes the adjusting support to be unable to quickly adjust to the preset angle. Summary of the Invention

[0004] The purpose of this application is to provide an adjustable support and a photovoltaic power generation device that can solve the problem that the rotating shaft of the current adjustable support cannot be quickly adjusted to a preset angle.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows:

[0006] In a first aspect, embodiments of this application provide an adjusting bracket, including a base and a rotating shaft for mounting equipment, wherein:

[0007] The base has a first surface, on which a mounting groove is formed, and an elastic limiting part is provided in the mounting groove, the elastic limiting part having a first limiting protrusion;

[0008] A rotating shaft has an end face located within a mounting groove. The end face is provided with a plurality of first limiting grooves, which are spaced apart along a direction surrounding the central axis of the rotating shaft.

[0009] When the rotating shaft is in the first position, the first limiting protrusion engages with the first limiting groove for limiting.

[0010] Secondly, embodiments of this application also provide a photovoltaic power generation device, including a photovoltaic panel assembly, an adjustment bracket, and a device body. The adjustment bracket is connected between the photovoltaic panel assembly and the device body. The adjustment bracket is the aforementioned adjustment bracket. The photovoltaic panel assembly includes a photovoltaic panel, a fixing plate, and a support bracket. The photovoltaic panel, the fixing plate, and the support bracket are stacked sequentially. The support bracket is connected to the adjustment bracket.

[0011] In this embodiment, when the shaft is in the first position, the first limiting protrusion and the first limiting groove are engaged, and there is no damping force between the shaft and the base. When the angle of the shaft needs to be adjusted, the shaft is rotated, causing the first limiting protrusion and the first limiting groove to disengage. At this time, the sidewalls of the two adjacent first limiting grooves are positioned opposite to the elastic limiting part, and the elastic limiting part undergoes elastic deformation. An additional damping force is formed between the shaft and the base, facilitating continued rotation of the shaft until it quickly rotates until the first limiting protrusion and the adjacent first limiting groove are engaged. At this point, the elastic limiting part returns to its original deformation, and the additional damping force between the shaft and the base disappears. Therefore, in this embodiment, an adjustable additional damping force can be formed between the shaft and the base, making the resistance between them variable, thereby quickly adjusting the shaft to a preset angle. Thus, the adjustment bracket disclosed in this embodiment can solve the problem that the shaft of current adjustment brackets cannot be quickly adjusted to a preset angle.

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0032] The adjustment bracket and photovoltaic power generation device provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0033] refer to Figures 1 to 10This application discloses an adjustment bracket, which includes a base 100 and a rotating shaft 200 for mounting a photovoltaic panel assembly 600. By rotating the rotating shaft 200 to a preset angle, the photovoltaic panel assembly 600 is rotated to improve the utilization rate of the photovoltaic panel assembly 600. Of course, this adjustment bracket can also be used to mount other equipment, such as cameras, etc., and this application does not impose specific limitations on this.

[0034] The base 100 serves as the basic component of the adjustment bracket, providing an installation foundation for other structures within the adjustment bracket. The base 100 has a first surface with a mounting groove 110. Optionally, the mounting groove 110 can be circular. An elastic limiting portion 120 is provided within the mounting groove 110, meaning the elastic limiting portion 120 can undergo elastic deformation. The elastic limiting portion 120 has a first limiting protrusion 121. Optionally, the first limiting protrusion 121 can be a conical structure or a trapezoidal boss; this embodiment does not impose specific limitations on this.

[0035] The first end of the rotating shaft 200 is connected to the photovoltaic panel assembly 600, and the second end is connected to the base 100. The rotating shaft 200 is used to adjust the angle of the photovoltaic panel assembly 600. The rotating shaft 200 has an end face 210, which can optionally be circular. The end face 210 is located at the second end of the rotating shaft 200 and is situated within the mounting groove 110. The end face 210 is provided with a plurality of first limiting grooves 211. Optionally, the first limiting grooves 211 can be V-shaped grooves, trapezoidal grooves, etc., without specific limitations. The plurality of first limiting grooves 211 are arranged at intervals along the direction surrounding the central axis of the rotating shaft 200. When the rotating shaft 200 is in the first position, the first limiting protrusion 121 and the first limiting groove 211 are engaged in a limiting engagement, and there is no damping force between the rotating shaft 200 and the base 100. When it is necessary to adjust the angle of the rotating shaft 200, the rotating shaft 200 is rotated to disengage the first limiting protrusion 121 from the first limiting groove 211. At this time, the sidewalls of the two adjacent first limiting grooves 211 are positioned opposite to the elastic limiting part 120, and the elastic limiting part 120 undergoes elastic deformation. An additional damping force is formed between the rotating shaft 200 and the base 100, so that the rotating shaft 200 can continue to rotate, and the rotating shaft 200 can be rotated quickly until the first limiting protrusion 121 and the adjacent first limiting groove 211 are engaged in a limiting engagement. At this time, the elastic limiting part 120 returns to its original deformation, and the additional damping force between the rotating shaft 200 and the base 100 disappears. Therefore, it can be seen that an adjustable additional damping force can be formed between the rotating shaft 200 and the base 100 in the embodiments of this application, so that the resistance between the rotating shaft 200 and the base 100 is variable, thereby quickly adjusting the rotating shaft 200 to a preset angle.

[0036] Optionally, when the first limiting protrusion 121 is a trapezoidal protrusion, the first limiting groove 211 is a trapezoidal groove, which has a guiding function, and this structure can enhance the stability of the limiting fit between the first limiting protrusion 121 and the first limiting groove 211.

[0037] When the first limiting protrusion 121 and the first limiting groove 211 are engaged, there is an assembly gap between them. Optionally, the assembly gap can be 0.1mm to 0.3mm. Of course, the assembly gap can also be other values. This application embodiment does not impose specific limitations on this.

[0038] In an optional embodiment, the bottom surface of the mounting groove 110 is provided with a clearance hole 111. The adjusting bracket also includes a rotating component 300 and a spring piece 400. The rotating component 300 is connected to the rotating shaft 200 through the clearance hole 111. Optionally, the rotating component 300 and the rotating shaft 200 can be fixedly connected by bonding, welding, or other connection methods. This application embodiment does not impose specific limitations on this. Optionally, the spring piece 400 can be a wave-shaped spring piece, which has strong buffering and vibration absorption capabilities and features good flexibility and impact resistance. Of course, it can also be a butterfly-shaped spring piece. This application embodiment does not impose specific limitations on this. The spring piece 400 is disposed between the base 100 and the rotating component 300. The rotating component 300 can rotate relative to the base 100 and press the spring piece 400, so that the spring piece 400 is in a compressed state. In this case, the rebound force of the spring piece 400 is the initial damping force between the base 100 and the rotating component 300, thereby improving the rotation efficiency of the rotating shaft 200.

[0039] In one optional embodiment, the elastic limiting portion 120 further has a second limiting protrusion 122. Optionally, the second limiting protrusion 122 can be a trapezoidal boss or an arc-shaped boss, without specific limitations. The first limiting protrusion 121 and the second limiting protrusion 122 are distributed at intervals along the circumference of the mounting groove 110. The end face 210 is also provided with a second limiting groove 212. Optionally, the second limiting groove 212 can be a trapezoidal groove or an arc-shaped groove, without specific limitations. When the rotating shaft 200 is in the second position, the second limiting protrusion 122 engages with the second limiting groove 212. At this time, the first limiting protrusion 121 engages with the first limiting groove 211, and the second limiting protrusion 122 engages with the second limiting groove 212 simultaneously, thereby strengthening the limiting effect on the rotating shaft 200. When it is necessary to adjust the angle of the rotating shaft 200, rotating the rotating shaft 200 causes the first limiting protrusion 121 to disengage from the first limiting groove 211 and the second limiting protrusion 122 to disengage from the second limiting groove 212 simultaneously. At this time, the two adjacent first limiting grooves 211... The sidewalls of the sidewalls and the two adjacent second limiting grooves 212 are all disposed opposite to the elastic limiting part 120. The elastic limiting part 120 undergoes elastic deformation, forming a greater additional damping force between the rotating shaft 200 and the base 100, thereby further facilitating the continued rotation of the rotating shaft 200. This allows the rotating shaft 200 to rotate quickly until the first limiting protrusion 121 engages with other first limiting grooves 211, and the second limiting protrusion 122 engages with the adjacent second limiting groove 212. At this point, the elastic limiting part 120 returns to its original deformation, and the additional damping force between the rotating shaft 200 and the base 100 disappears. Thus, it can be seen that the second limiting protrusion 122 and the second limiting groove 212 enable a greater additional damping force to be formed between the rotating shaft 200 and the base 100, thereby allowing the rotating shaft 200 to be adjusted to the preset angle more quickly.

[0040] Optionally, when the second limiting protrusion 122 is an arc-shaped boss, the second limiting groove 212 can be an arc-shaped groove. The radius of the second limiting protrusion 122 is smaller than the radius of the second limiting groove 212. When the second limiting protrusion 122 and the second limiting groove 212 are engaged, the central axis of the second limiting protrusion 122 coincides with the central axis of the second limiting groove 212, so that the second limiting protrusion 122 can smoothly engage or disengage with the second limiting groove 212, thereby improving the rotation efficiency of the rotating shaft 200. Further optionally, the difference between the radius of the second limiting groove 212 and the radius of the second limiting protrusion 122 can be 0.05mm to 0.3mm. Of course, the difference between the two can also be other values, which are not specifically limited here.

[0041] The first limiting protrusion 121 and the second limiting protrusion 122 can be disposed on the same plane, with the second limiting protrusion 122 located on the side of the first limiting protrusion 121 closer to the central axis of the rotating shaft 200. In this case, the connection area between the rotating shaft 200 and the base 100 is small, resulting in poor connection stability of the rotating shaft 200. Therefore, optionally, the elastic limiting part 120 has adjacent second surface 123 and third surface 124, with the first limiting protrusion 121 disposed on the second surface 123 and the second limiting protrusion 122 disposed on the third surface 124. This increases the connection area between the rotating shaft 200 and the base 100, thereby improving the connection stability between the rotating shaft 200 and the base 100.

[0042] In a further optional embodiment, the elastic limiting part 120 includes a first elastic limiting part and a second elastic limiting part. The first elastic limiting part and the second elastic limiting part are stacked along the central axis direction of the end face 210. When the first limiting protrusion 121 and the second limiting protrusion 122 are both provided on the first elastic limiting part, the second limiting protrusion 122 and the first limiting groove 211 are prone to interference during the rotation of the rotating shaft 200, thereby increasing the difficulty of setting the first limiting groove 211 and the second limiting groove 212. Based on this, a first limiting protrusion 121 is disposed on a first elastic limiting portion, a second limiting protrusion 122 is disposed on a second elastic limiting portion, and an end face 210 has an annular convex wall 220. Optionally, the central axis of the annular convex wall 220 coincides with the central axis of the end face 210, and a second limiting groove 212 is disposed on the annular convex wall 220. In this case, the distance between the second limiting protrusion 122 and the first limiting groove 211 can be increased in the central axis direction, thereby avoiding interference between the second limiting protrusion 122 and the first limiting groove 211, and reducing the difficulty of setting the first limiting groove 211 and the second limiting groove 212.

[0043] In another optional embodiment, the mounting groove 110 is further provided with a stop part 130, which is located on the side of the first limiting protrusion 121 opposite to the second limiting protrusion 122. The edge of the end face 210 is also provided with a protrusion 230. When the rotating shaft 200 is in the third position, the stop part 130 and the protrusion 230 limit the rotation, thereby preventing the rotating shaft 200 from continuing to rotate. At the same time, it can reduce the wear of the rotating part 300 on the spring 400, thereby extending the service life of the spring 400. In addition, during the rotation of the rotating shaft 200, the setting of the stop part 130 can enable the rotating shaft 200 to rotate accurately and quickly to the preset angle, thereby improving the adjustment efficiency of the adjustment bracket.

[0044] An annular groove can be formed on the side wall of the mounting groove 110. The stop part 130 includes a side portion, and the protrusion 230 can cooperate with the side portion for limiting. The stop part 130 with this structure can only limit the rotating shaft 200 in the radial direction. Therefore, optionally, the stop part 130 also includes a top portion, which is connected to the side portion and faces the bottom surface of the mounting groove 110. When the rotating shaft 200 is in the third position, the protrusion 230 is located between the top portion and the bottom surface of the mounting groove. The protrusion 230 can cooperate with both the top portion and the side portion for limiting. This stop part 130 not only limits the rotating shaft 200 in the radial direction but also in the axial direction, thereby preventing the first limiting protrusion 121 and the second limiting protrusion 122 from disengaging from the first limiting groove 211 and the second limiting groove 212, respectively. Therefore, the stop part 130 with this structure can improve the connection stability between the rotating shaft 200 and the base 100.

[0045] The number of elastic limiting parts 120 can be one, two, or even more. Optionally, the number of elastic limiting parts 120 is one. In this case, during the rotation of the rotating shaft 200, the connection area between the rotating shaft 200 and the base 100 is small, and the stability of the rotating shaft 200 is poor. Therefore, in a further optional embodiment, the number of elastic limiting parts 120 is at least two. Each elastic limiting part 120 is arranged at intervals along the circumference of the mounting groove 110, and each elastic limiting part 120 is evenly distributed along the circumference of the mounting groove 110. Each elastic limiting part 120 is provided with at least one first limiting protrusion 121 and at least one second limiting protrusion 122. That is, the number of first limiting protrusions 121 can be one or more, and similarly, the number of second limiting protrusions 122 can be one or more. The second limiting groove 212 and the second limiting protrusion 122 are respectively provided in a one-to-one correspondence. Each first limiting protrusion 121 is respectively limited and engaged with a portion of the first limiting groove 211, and each second limiting protrusion 122 is respectively limited and engaged with each second limiting groove 212, thereby increasing the connection area between the rotating shaft 200 and the base 100, so that when the rotating shaft 200 is in the second position, the connection between the rotating shaft 200 and the base 100 is more stable, thereby improving the stability of the entire adjustment bracket.

[0046] When each elastic limiting part 120 is provided with a first limiting protrusion 121 and a second limiting protrusion 122, the first limiting protrusion 121 may be provided at the end of the elastic limiting part 120, and the second limiting protrusion 122 may be provided at the middle position of the elastic limiting part 120, thereby increasing the rotation angle of the rotating shaft 200, providing more working positions for the photovoltaic panel module 600, and thus improving the utilization rate of the photovoltaic panel module 600.

[0047] In an optional embodiment, the end face 210 is provided with a connecting hole 213. Optionally, the connecting hole 213 can be located in the central area of ​​the end face 210. The rotating member 300 is provided with a first through hole 320. The adjusting bracket also includes a connecting member 500. One end of the connecting member 500 passes through the first through hole 320 and engages with the connecting hole 213, so that the rotating shaft 200 and the rotating member 300 are detachably connected, facilitating the disassembly and maintenance of the adjusting bracket. The connecting member 500 and the connecting hole 213 can be connected by friction. However, this connection method is not convenient for disassembling and assembling the adjusting bracket and is prone to damaging the rotating shaft 200. Therefore, optionally, the connecting hole 213 can be a threaded connecting hole, and the connecting member 500 can be a threaded connecting member. One end of the threaded connecting member passes through the first through hole 320 and engages with the threaded connecting hole, facilitating the disassembly and maintenance of the adjusting bracket. This connection method can also protect the rotating shaft 200.

[0048] In one optional embodiment, the end face 210 may be provided with a connecting portion 240, and a connecting hole 213 is provided in the connecting portion 240, thereby increasing the connection area between the connector 500 and the rotating shaft 200, so as to improve the connection stability between the rotating member 300 and the rotating shaft 200.

[0049] In another optional embodiment, the end face 210 may be provided with a positioning part 250, and the rotating part 300 is provided with a positioning hole 330. The positioning part 250 and the positioning hole 330 are positioned and engaged, thereby providing a guide for the connector 500 so that the connector 500 can be quickly inserted into the connecting hole 213, thereby improving the assembly efficiency of the adjustment bracket.

[0050] It should be noted that the connecting part 240 and the positioning part 250 can be simultaneously provided on the end face 210 of the rotating shaft 200, which can improve the connection efficiency of the connecting member 500 and the connection stability between the rotating member 300 and the rotating shaft 200.

[0051] The side of the rotating member 300 opposite to the rotating shaft 200 can be a plane. When part of the elastic limiting part 120 is outside the mounting groove 110, the distance between the rotating member 300 and the base 100 is relatively large, resulting in a larger deformation space for the spring piece 400. In this case, the spring piece 400 is prone to tilting when it deforms. Furthermore, the large distance between the rotating member 300 and the base 100 increases the design difficulty of the spring piece 400. Therefore, in an optional embodiment, the rotating member 300 is provided with a relief groove 310. The relief groove 310 is provided on the side of the rotating member 300 facing the rotating shaft 200, and part of the elastic limiting part 120 is provided in the relief groove 310, thereby shortening the distance between the rotating member 300 and the base 100, preventing the spring piece 400 from tilting when it deforms, and reducing the design difficulty of the spring piece 400.

[0052] In an optional embodiment, the base 100 is provided with a receiving groove 140, which is located on the side of the base 100 facing the rotating member 300. The spring piece 400 is disposed in the receiving groove 140. The receiving groove 140 can not only provide a receiving space for the spring piece 400, but also provide guidance for the elastic deformation of the spring piece 400, making the entire adjustment bracket more compact and stable.

[0053] Based on the adjustment bracket described in the above embodiments, this application also provides a photovoltaic power generation device, which includes a photovoltaic panel assembly 600, an adjustment bracket, and a device body 700. The adjustment bracket is connected between the photovoltaic panel assembly 600 and the device body 700. The adjustment bracket is the adjustment bracket described in any of the above embodiments. The photovoltaic panel assembly 600 includes a photovoltaic panel 610, a fixing plate 620, and a support bracket 630. The photovoltaic panel 610, the fixing plate 620, and the support bracket 630 are stacked in sequence, and the support bracket 630 is connected to the adjustment bracket.

[0054] Optionally, the photovoltaic power generation device also includes a threaded connector 800. The support bracket 630 has a second through hole, and the first end of the rotating shaft 200 has a threaded connection hole. One end of the threaded connector 800 passes through the second through hole and is threadedly engaged with the threaded connection hole, so that the support bracket 630 and the rotating shaft 200 are fixedly connected. When the rotating shaft 200 rotates, it will drive the entire photovoltaic panel assembly 600 to rotate, thereby adjusting the photovoltaic panel assembly 600 to a preset angle to improve the utilization rate of the photovoltaic panel 610.

[0055] In one optional embodiment, the device body 700 includes a housing 710 with an accommodating space. Other components of the device body 700 can be housed within this accommodating space, and the housing 710 protects the other structures within the accommodating space. The housing 710 includes a base 100, meaning the housing 710 of the device body 700 is directly used as the base 100. The base 100 and the housing 710 are an integral structure. In this case, the housing 710 can both protect the components within the accommodating space and serve as the base 100 for the adjustment bracket. This means the housing 710 has a dual-purpose effect, saving material for manufacturing the adjustment bracket. Furthermore, directly using the housing 710 of the device body 700 as the base 100 simplifies the assembly of the entire photovoltaic power generation device. Alternatively, the base 100 and the housing 710 can be separate structures. In this case, the base 100 and the housing 710 can be fixedly connected by bolts, welding, or other methods. However, separate structures are inconvenient for the installation of photovoltaic power generation devices and occupy more space. Therefore, a separate structure for the base 100 and the outer shell 710 is not as effective as an integrated structure.

[0056] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
