Detailed Description

Specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the disclosure, are not intended to limit the disclosure.

In the present disclosure, unless otherwise indicated, terms of orientation such as "upper and lower" are generally defined in terms of normal use of the photovoltaic bracket, and are specifically shown with reference to fig. 2 and 3, while "inner and outer" refer to inner and outer of the outline of the corresponding component, and furthermore, terms such as "first", "second", etc. are used to distinguish one element from another, without sequence or importance.

As shown in fig. 1 to 9, the present disclosure provides a photovoltaic bracket, including a mounting bracket 10, a support bracket 20, a clamping assembly 30 and an extrusion structure 40, the mounting bracket 10 is used for mounting a photovoltaic panel, the support bracket 20 is disposed below the mounting bracket 10 and is used for supporting the mounting bracket 10, the clamping assembly 30 is mounted at an upper end of the support bracket 20 and includes a pair of clamping portions 31, an insertion slot 11 and a clamping hole 12 communicating with the insertion slot 11 are disposed on the mounting bracket 10, the pair of clamping portions 31 can be inserted into the insertion slot 11 and elastically opened to connect the support bracket 20 to the mounting bracket 10 through the clamping hole 12, a first end of the extrusion structure 40 is located outside the mounting bracket 10 and has a pressing portion 41, a second end of the extrusion structure 40 is used for abutting against the clamping portion 31, and the second end of the extrusion structure 40 can extrude the clamping portion 31 when the pressing portion 41 receives an external force in a direction approaching the clamping portion 31, so that the clamping portion 31 is separated from the clamping hole 12.

The assembly process between the mounting bracket 10 and the support bracket 20 may be: the pair of clamping parts 31 of the clamping assembly 30 are inserted into the insertion groove 11, when the pair of clamping parts 31 are inserted to be opposite to the clamping holes 12, the pair of clamping parts 31 can be elastically opened and pass through the clamping holes 12, at this time, the clamping assembly 30 and the mounting bracket 10 are mutually locked, and the connection between the mounting bracket 10 and the supporting bracket 20 is completed.

The disassembly process between the mounting bracket 10 and the supporting bracket 20 may be: the pressing portion 41 is pressed in a direction approaching the locking portion 31, so that the second end of the pressing structure 40 presses the pair of locking portions 31 into the insertion groove 11, and when the pair of locking portions 31 are separated from the locking hole 12, the locking between the locking assembly 30 and the insertion groove 11 is released, and at this time, the pair of locking portions 31 can be pulled out of the insertion groove 11, thereby completing the detachment between the mounting bracket 10 and the support bracket 20.

With the above-described configuration, since the pair of the engaging portions 31 can be inserted into the insertion groove 11 and elastically spread, and the insertion groove 11 communicates with the engaging hole 12, that is, when the pair of engaging portions 31 are facing the engaging hole 12, the groove wall of the insertion groove 11 loses the restraint of the pair of engaging portions 31, and therefore, the pair of engaging portions 31 can elastically spread and pass through the engaging hole 12. Because the clip assembly 30 is mounted at the upper end of the support bracket 20 and the insertion groove 11 is provided on the mounting bracket 10, the clip assembly 30 and the mounting bracket 10 are locked to each other in a state where the pair of clip portions 31 pass through the clip holes 12, and connection between the mounting bracket 10 and the support bracket 20 can be achieved.

In addition, since the pressing structure 40 is movably mounted to the mounting bracket 10, and the first end of the pressing structure 40 is located outside the mounting bracket 10 and has the pressing portion 41, that is, the operator can press the pressing portion 41 outside the mounting bracket 10 from the outside of the mounting bracket 10 toward the direction approaching the clamping portion 31, so that the second end of the pressing structure abuts against and presses the clamping portion 31, thereby releasing the clamping portion 31 from the clamping hole 12, when the pair of clamping portions 31 are released from the clamping hole 12, the locking between the clamping assembly 30 and the mounting bracket 10 is released, and at this time, the pair of clamping portions 31 can be pulled out of the insertion groove 11, thereby achieving the detachment between the mounting bracket 10 and the support bracket 20. It will be appreciated that since the squeeze structure 40 is movably mounted to the mounting bracket 10, an operator can manipulate the movement of the squeeze structure 40 from outside the mounting bracket 10 such that the second end of the squeeze structure 40 does not obstruct the pair of the snap-fit portions 31 from passing through the snap-fit holes 12.

Compared with the technical scheme that bolts and nuts are used for assembling the mounting bracket and the supporting bracket in the related art, the photovoltaic bracket provided by the disclosure does not use the bolts and the nuts as connecting pieces between the mounting bracket 10 and the supporting bracket 20, so that the mounting bracket 10 and the supporting bracket 20 can be connected and disassembled without tools, the situation that sliding wires or biting between the bolts and the nuts occur is avoided, and the photovoltaic bracket assembling and disassembling efficiency is improved.

In one embodiment provided in the present disclosure, as shown in fig. 4, 7 and 8, the mounting bracket 10 may include a bracket body 13 for mounting a photovoltaic panel and a protrusion structure 14 mounted on the bracket body 13, the bracket body 13 is formed with a through hole 111, the protrusion structure 14 is formed with a groove 112 opened toward the through hole 111, the through hole 111 and the groove 112 together form an insertion groove 11, the clamping hole 12 is formed on the protrusion structure 14, the protrusion structure 14 is further formed with a mounting hole 141, the mounting hole 141 is located at a side of the groove 112 facing away from the through hole 111 and communicates with the groove 112, and the pressing structure 40 is movably mounted at the mounting hole 141. The mounting hole 141 can guide the movement of the pressing structure 40, and when the pressing portion 41 is pressed in a direction approaching the locking portion 31, the pressing structure 40 moves along the mounting hole 141, so that the second end of the pressing structure 40 can press the locking portion 31. In addition, the clamping hole 12 is formed on the protruding structure 14, so that an operator can conveniently observe whether the clamping portion 31 passes through the clamping hole 12 from the outside, and the support bracket 20 is ensured to be firmly connected with the mounting bracket 10.

In another embodiment provided by the present disclosure, the mounting bracket 10 may include a bracket body 13 for mounting a photovoltaic panel, the insertion groove 11 is formed on the bracket body 13, the clamping hole 12 is formed in the bracket body 13, the bracket body 13 is formed with a mounting hole 141, and the mounting hole 141 is opposite to the clamping hole 12 and communicates with the clamping hole 12, and the pressing structure 40 is movably mounted to the mounting hole 141.

In order to enable the extrusion structure 40 to extrude the pair of clamping portions 31, the pair of clamping portions 31 simultaneously separate from the clamping holes 12, as an embodiment, as shown in fig. 4, the extrusion structure 40 includes a pair of extrusion rods 42, each extrusion rod 42 is correspondingly provided with a mounting hole 141, a first end of each extrusion rod 42 is located outside the protruding structure 14, and a second end of each extrusion rod 42 movably passes through the corresponding mounting hole 141 and is used for abutting against the corresponding clamping portion 31, and the pressing portion 41 is connected to the first ends of the pair of extrusion rods 42. Since the pressing portion 41 is connected to the first ends of the pair of pressing rods 42, the operator can move the second ends of the pair of pressing rods 42 together by pressing the pressing portion 41 and press the corresponding engaging portions 31, respectively, so that the pair of engaging portions 31 simultaneously come out of the engaging holes 12.

In other embodiments, the first ends of the pair of engaging portions 31 may be connected to the two pressing portions 41, which is not limited in this disclosure.

In order to prevent the extrusion rods 42 from being separated from the mounting holes 141 in the moving process, as shown in fig. 4, limiting blocks 421 are formed on each extrusion rod 42, limiting grooves 142 which are arranged in one-to-one correspondence with the mounting holes 141 are further formed on the protruding structures 14, the extending direction of each limiting groove 142 is parallel to the axial direction of the mounting hole 141, each limiting groove 142 is communicated with the corresponding mounting hole 141, and each limiting block 421 is movably contained in each limiting groove 142. Since the extending direction of the limiting groove 142 is parallel to the axial direction of the mounting hole 141, and the limiting block 421 formed on the extrusion rod 42 is movably accommodated in the limiting groove 142, the extrusion rod 42 can only move within a limited range along the axial direction of the mounting hole 141, and the extrusion rod 42 can be prevented from falling out of the mounting hole 141 without affecting the use of the extrusion rod 42.

Since the photovoltaic module is generally used in an open air environment, if rainwater enters the mounting hole 141 and the insertion groove 11 for a long period of time, corrosion of the clamping assembly 30 and the pressing structure 40 may be caused, in order to reduce the rainwater entering the mounting hole 141 and the insertion groove 11, as an embodiment, as shown in fig. 7 and 8, the module body 13 includes a U-shaped body portion 131 having an upward opening, two burring portions 132 formed at an upper end of a side portion of the U-shaped body portion 131, the burring portions 132 are used for mounting the photovoltaic panel, the through-hole 111 is formed at a bottom of the U-shaped body portion 131, and the protrusion structure 14 is mounted at a bottom of the U-shaped body portion 131. When the photovoltaic panel is mounted on the two flange portions 132, the opening of the U-shaped main body portion 131 can be blocked, and the protruding structure 14, the pressing structure 40 and the clamping assembly 30 are blocked from above, so that rainwater entering the mounting hole 141 and the insertion groove 11 from above is effectively reduced, and the possibility that the clamping assembly 30 and the pressing structure 40 are corroded to be unfavorable for disassembly is reduced.

In order to enable the pair of the clamping portions 31 to be inserted into the insertion groove 11 and to be elastically opened, as an embodiment, as shown in fig. 4, the clamping assembly 30 further includes a connection member 32 and an elastic member 33, the connection member 32 is mounted at an upper end of the support bracket 20, the pair of the clamping portions 31 is movably mounted to the connection member 32, and the elastic member 33 is connected between the pair of the clamping portions 31. Since the elastic member 33 is connected between the pair of the engaging portions 31, the elastic member 33 can be compressed, so that the pair of engaging portions 31 can be inserted into the insertion groove 11, and when the engaging portions 31 are opposite to the engaging holes 12, the pair of engaging portions 31 can be opened and pass through the engaging holes 12 by the resilient action of the elastic member 33.

Here, the elastic member 33 may be a coil spring or an elastic bellows, and the present disclosure is not limited to this as long as the pair of engagement portions 31 can be elastically expanded.

As another embodiment, the clamping assembly 30 further includes a connecting member 32, and the pair of clamping portions 31 are "several" shaped elastic members, wherein the connecting member 32 is mounted on the upper end of the support bracket 20, and the "several" shaped elastic members are mounted on the connecting member 32.

In order to facilitate the second end of the pressing structure 40 to press the clamping portion 31, the clamping portion 31 is disengaged from the clamping hole 12, as an embodiment, as shown in fig. 4, an end surface of the pressing structure 40, which is used to abut against the clamping portion 31, is formed as a first inclined surface, and a surface of the clamping portion 31, which is used to contact with the pressing structure 40, is formed as a second inclined surface that is matched with the first inclined surface. Because the end surface of the extrusion structure 40 abutting against the clamping portion 31 is formed into a first inclined surface, and the surface of the clamping portion 31 contacting with the extrusion structure 40 is formed into a second inclined surface matched with the first inclined surface, when the extrusion structure 40 extrudes the clamping portion 31 in a direction approaching to the clamping portion 31, the clamping portion 31 can be separated from the clamping hole 12, and the clamping portion 31 can be moved downwards in the insertion groove 11 for a certain distance after the clamping portion 31 is separated from the clamping hole 12, so that the clamping portion 31 is not aligned with the clamping hole 12, and the clamping portion 31 is prevented from being elastically opened again.

In addition, since the second inclined surface can be brought into contact with the notch of the insertion groove 11 during insertion of the pair of the engaging portions 31 into the insertion groove 11, it is possible to contribute to a reduction in resistance during insertion of the pair of the engaging portions 31 into the insertion groove 11.

It will be appreciated that for embodiments in which the extrusion 40 includes the extrusion 42, the first chamfer is formed on the end surface of the extrusion 42 adjacent the clip portion 31.

Alternatively, as shown in fig. 2 and 3, the support bracket 20 may include a first support bracket 21 and a second support bracket 22, each of the first support bracket 21 and the second support bracket 22 includes a vertical support rod 23, at least one of the first support bracket 21 and the second support bracket 22 further includes an inclined support rod 24, the inclined support rod 24 is connected to the vertical support rod 23, and at least one clamping assembly 30 is mounted to both an upper end of the vertical support rod 23 and an upper end of the inclined support rod 24. Along with the increase of the service time of the photovoltaic panel, the part of the mounting bracket 10 which is lack of the support bracket 20 is likely to be bent and deformed under the influence of gravity, the mode of increasing the vertical support rods 23 has higher requirements on the flatness of the mounting ground, the mounting difficulty of the photovoltaic bracket is increased, and the supporting points of the mounting bracket 10 can be increased under the condition that the flatness requirements on the mounting ground are not increased by arranging the inclined support rods 24, so that the possibility of bending and deformation of the mounting bracket 10 is reduced.

Through all installing at least one joint subassembly 30 in the upper end of vertical bracing piece 23 and the upper end of diagonal brace 24 for vertical bracing piece 23 and diagonal brace 24 all can be with the installing support 10 under the condition of not using bolt and nut and other instrument and dismantle.

Alternatively, as shown in fig. 1 to 3, the support bracket 20 may further include a claw-shaped structure by which claw ends are used to be supported at the bottom of the mounting bracket 10 to reduce the possibility of bending deformation of the mounting bracket 10 due to gravity.

Alternatively, as shown in fig. 9, the support bracket 20 includes a vertical support rod 23, the vertical support rod 23 includes a fixed rod 231 and a movable rod 232 located above the fixed rod 231, the clamping assembly 30 is installed at the upper end of the movable rod 232, the support bracket 20 further includes a height adjusting assembly 25, the height adjusting assembly 25 includes a threaded rod 251 and an operation ring 252, the threaded rod 251 is installed at the upper end of the fixed rod 231, a cylindrical groove 2321 for inserting the threaded rod 251 is provided on the movable rod 232, the operation ring 252 is sleeved on the threaded rod 251 and is in threaded connection with the threaded rod 251, and the upper end face of the operation ring 252 is used for propping up the lower end of the movable rod 232.

Because the operation ring 252 is sleeved on the threaded rod 251 and is in threaded connection with the threaded rod 251, rotating the operation ring 252 around the threaded rod 251 can enable the operation ring 252 to move along the axial direction of the threaded rod 251, and because the upper end face of the operation ring 252 is used for abutting the lower end of the movable rod 232, when the operation ring 252 moves towards the upper end of the threaded rod 251, the movable rod 232 can be pushed to synchronously rise, and when the operation ring 252 moves towards the lower end of the threaded rod 251, the movable rod 232 can synchronously descend along with the operation ring 252 under the action of gravity, so that the length of the vertical support rod 23 is adjusted.

It should be noted that the threaded rod 251 and the operating ring 252 can be self-locked by threads.

In order to avoid friction between the external thread of the threaded rod 251 and the groove wall of the cylindrical groove 2321, as shown in fig. 5, as an embodiment, a gap is formed between the groove wall of the cylindrical groove 2321 and the outer circumferential surface of the threaded rod 251, a guide block 2511 is disposed at the upper end of the threaded rod 251, and one end of the guide block 2511 away from the threaded rod 251 is in contact with the groove wall of the cylindrical groove 2321. By the contact of the guide block 2511 with the groove wall of the cylindrical groove 2321, a gap is always kept between the groove wall of the cylindrical groove 2321 and the outer circumferential surface of the threaded rod 251, so that friction between the threads of the threaded rod 251 and the groove wall of the cylindrical groove 2321 is avoided. Further, since the guide block 2511 is provided at the upper end of the threaded rod 251, interference with the operation ring 252 can be prevented to the greatest extent.

Alternatively, as shown in fig. 6, the movable rod 232 is formed with a ring groove 2322 coaxial with the cylindrical groove 2321, the operating ring 252 is mounted with the ring element 2521, the ring element 2521 is slidably clamped in the ring groove 2322 and can rotate around the axis of the cylindrical groove 2321, and the operating ring 252 can drive the ring element 2521 to synchronously rotate when rotating. The limit of the ring groove 2322 to the ring piece 2521 can enable the operating ring 252 to better drive the movable rod 232 to move synchronously along the axial direction of the threaded rod 251.
