[0004] The above patent records a photovoltaic tile. In order to facilitate transportation and installation, the area of ​​photovoltaic tiles in the prior art is usually not very large. The staff can first install the bracket on the roof, and then overlap the photovoltaic tiles and install them on the bracket to assemble the photovoltaic tiles into a solar roof. In order to make the photovoltaic tiles and the bracket firmly installed, the staff usually use bolt connection to install them. This connection method has good fixation and ensures that the photovoltaic tiles are not easily blown by strong winds. However, the bolt connection method requires the staff to install bolts at each reinforcement point of each photovoltaic tile, which is a large workload. In addition, photovoltaic tiles are usually installed on sloping roofs. The installation environment of photovoltaic tiles is relatively special. If the traditional bolt connection method is used for installation, the operation is difficult. Therefore, the overlap method of photovoltaic tiles can be improved. Utility Model Content

DETAILED DESCRIPTION

[0025] In order to further explain the technical solution of the present utility model, it is described in detail through specific embodiments below.

[0027] See also Figure 2-5The quick lap joint mechanism 3 in the utility model includes a lap joint 31, a buckle groove 32, a slot 33, a positioning pin 34 and a quick locking mechanism 35. The lap joint 31 is screwed on both the front and rear sides of the bottom of the photovoltaic tile 1. A buckle groove 32 is provided at the bottom of the lap joint 31, and the buckle groove 32 passes through the lap joint 31 on the left and right. The bracket 2 is a square tube with a hollow interior. A pair of parallel slots 33 are provided on the top surface of the bracket 2. The bottom end of the lap joint 31 can be buckled into the slot 33 and extend into the interior of the bracket 2. A positioning pin 34 is slidably installed inside the bracket 2, and the positioning pin 34 can slide horizontally along the interior of the bracket 2. After the lap joint 31 is completely buckled into the slot 33, the positioning pin 34 can pass through the buckle groove 32 horizontally to lock the lap joint 31 with the bracket 2. The head end of the positioning pin 34 extends out of the interior of the bracket 2, and a quick locking mechanism 35 is provided at the positioning pin 34 and the head end of the bracket 2.

[0028] To further explain, a narrow side section 341 is provided on the positioning pin 34, and the width of the narrow side section 341 is smaller than the width of the bottom opening of the buckle groove 32. The buckle groove 32 can be first buckled on the surface of the narrow side section 341, and then the positioning pin 34 is passed horizontally through the buckle groove 32, so as to lock the lap joint 31 and the bracket 2.

[0029] It is further explained that the number of narrow side segments 341 on the positioning pin 34 is consistent with the number of slots 33 on the bracket 2, and the positions of the narrow side segments 341 correspond to the slots 33. By moving the positioning pin 34, all connected lap parts 31 on the bracket 2 can be unlocked or locked at the same time, making the disassembly and assembly operations more convenient.

[0030] To further explain, at least four lap joints 31 are installed on the bottom surface of the photovoltaic tile 1, and the lap joints 31 are symmetrically distributed on the left and right sides of the bottom surface of the photovoltaic tile 1. Since the photovoltaic tile 1 is connected to the bracket 2 through the lap joints 31, the four lap joints 31 can provide sufficient connection points between the photovoltaic tile 1 and the bracket 2 to ensure the installation strength of the photovoltaic tile 1.

[0031] See also Figure 6 The quick locking mechanism 35 in the utility model includes a buckle portion 351, a connecting seat 352, a knob 353, a torsion spring 354 and a locking piece 355. The head end of the locating pin 34 is integrally provided with a buckle portion 351, a connecting seat 352 is welded and fixed on the top of the head end of the bracket 2, a knob 353 is rotatably mounted on the right side of the connecting seat 352, the connecting seat 352 and the knob 353 are rotatably connected by a bearing, the shaft body on the left side of the knob 353 passes through the inner side of the connecting seat 352, a torsion spring 354 is sleeved on the shaft body surface of the knob 353, and the torsion spring 354 is connected to the inner side of the connecting seat 352, so that the knob 353 can rotate under the elastic force of the torsion spring 354, and a locking piece 355 is bonded and fixed to the end of the shaft body of the knob 353, and the locking piece 355 is located on the left side of the connecting seat 352.

[0032] To further explain, the locking member 355 is cam-shaped, and the through groove on the inner side of the buckle portion 351 matches the shape and size of the locking member 355. After the locking member 355 is rotated to an angle consistent with the inner side of the buckle portion 351, the locking member 355 can pass through the inner side of the buckle portion 351, and then the locking member 355 is rotated again to make its angle offset from the inner side of the buckle portion 351. At this time, the locking member 355 can clamp the buckle portion 351 to restrict its movement and reset, thereby achieving the effect of locking the position of the positioning pin 34.

[0033] To further explain, the maximum flip angle of the knob 353 is 180 degrees. After the knob 353 is rotated to the maximum angle against the torsion spring 354, the locking member 355 is at the same angle as the inner side of the buckle portion 351, which can facilitate the staff to quickly position the locking member 355 to the angle corresponding to the buckle portion 351.

[0034] Here’s how it works:

[0035] First, the solar roof can generate solar power by installing photovoltaic tiles 1 on the roof structure to achieve the effect of energy conservation and emission reduction. Before installing the photovoltaic tiles 1, the bracket 2 needs to be installed on the roof first to serve as the supporting structure of the photovoltaic tiles 1.

[0036] Second, after the installation of the bracket 2 is completed, the installation of the photovoltaic tile 1 can begin. The lock of the locating pin 34 needs to be unlocked first. First, the knob 353 is rotated to the maximum angle against the torsion spring 354. At this time, the locking piece 355 is consistent with the inner angle of the buckle part 351, so that the buckle part 351 can pass through the locking piece 355 to release the lock of the locating pin 34. The staff needs to move the locating pin 34 from the inside of the bracket 2 to the maximum stroke distance to move the narrow edge section 341 on the locating pin 34 to the bottom of the slot 33, and then place the photovoltaic tile 1 on the top of the bracket 2, and ensure that the lap joint 31 on the bottom of the photovoltaic tile 1 is fully buckled into the slot. The lap joint 31 is fixed to the bracket 2 by the locating pin 34. The lap joint 31 is fixed to the bracket 2 by the locating pin 34. The lap joint 31 is fixed to the bracket 2 by the locating pin 34. The lap joint 31 is fixed to the bracket 2 by the locating pin 34.

[0037] The locking member 355 is then engaged with the locking member 355 and the locking member 351 is engaged with the locking member 355.

[0038] The utility model provides a photovoltaic tile overlapping structure, by setting a quick overlapping mechanism 3 at the connection between the photovoltaic tile 1 and the bracket 2, by placing the photovoltaic tile 1 on the top of the bracket 2, and ensuring that the overlapping parts 31 on the bottom surface of the photovoltaic tile 1 are all snapped into the slot 33, and then pushing the positioning pin 34 into the inside of the bracket 2 from the outside to the inside, the connection and fixation between the photovoltaic tile 1 and the bracket 2 are achieved, and all the connected overlapping parts 31 on the bracket 2 can be locked at the same time by moving the positioning pin 34, without the need to reinforce them one by one, thereby simplifying the installation operation process and further improving the installation efficiency, and by setting a quick locking mechanism 35 at the positioning pin 34 and the head end of the bracket 2, because the photovoltaic tile 1 is usually installed on a sloping roof, the installation environment is relatively special, which will increase the difficulty of operation, and the quick locking mechanism 35 can allow the staff to quickly lock the position of the positioning pin 34, and the applicability is better.
