[0028] In the description of the present utility model, it should be understood that the orientation or positional relationships indicated by the terms "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0029] Please refer to Figures 1-4, A kind of frameless photovoltaic module shown, which includes a frame member 1 and a pressing block member 2. The frame member 1 is fixedly installed on the photovoltaic bracket through the pressing block member 2. A clamping groove 1e is provided in the middle of the first side plate 1a, and an anti-seepage groove 1f is designed at the upper end of the clamping groove 1e. The pressing block member 2 includes a pressing block 2a that fits with the clamping groove 1e and an anti-seepage boss 2e that fits with the anti-seepage groove 1f.

[0030] The clamping groove 1e is designed in a parallelogram-like structure. When the pressing block 2a is connected to the clamping groove 1e, it is connected by an interference fit. When using the pressing block member 2 to fixedly install the frame member 1 on the photovoltaic bracket, the pressing block 2a is clamped in the clamping groove 1e, and the downward pressure is provided through its parallelogram structure design, so as to achieve the purpose of pressing the frame member 1. Compared with the traditional method of pressing the A side of the frame by a pressing block, such a pressing and installation mode can effectively ensure that the height of the frame is on the same plane as the photovoltaic panel, so that the photovoltaic panel presents a flat structure after being installed on the frame. And when the anti-seepage boss 2e is connected to the anti-seepage groove 1f, some glue can be coated on the surface of the anti-seepage groove 1f, which can better improve the sealing performance after the connection of the two, effectively prevent the penetration of rainwater, and improve the durability of the device.

[0031] The frame member 1 includes a first side plate 1a, a second side plate 1b, a lower support plate 1c, an upper support plate 1d and a corner code connection cavity 1d. There is a set of reinforcing ribs on the upper and lower inner end faces of the connecting corner code cavity 1d. The first side plate 1a and the second side plate 1b are symmetrically designed respectively. The lower support plate 1c is fixedly connected to the lower end faces of the first side plate 1a and the second side plate 1b respectively. One end of the upper support plate 1d is fixedly connected to the side of the first side plate 1a. The lower end face of the upper support plate 1d is fixedly connected to the top of the second side plate 1b. And the end of the upper support plate 1d away from the first side plate 1a extends to the outside of the second side plate 1b. At the same time, the first side plate 1a, the second side plate 1b, the upper support plate 1d and the lower support plate 1c are integrally formed structures.

[0032] A first glue application area 1g and a pressure relief area 1h are provided on the first side plate 1a. A second glue application area 1j is provided on the upper support plate 1d. And the first glue application area 1g, the pressure relief area 1h and the second glue application area 1j are connected. The side of the first glue application area 1g close to the pressing block member 2 is designed in a undulating wavy shape.

[0033] When installing the photovoltaic panel on this device, apply the special glue for adhesion on the glue application area 1g and the glue application area 1j to connect the photovoltaic panel with the upper support plate 1d. Since the applied glue will flow under the downward pressure of the photovoltaic panel, the glue flowing due to extrusion is likely to penetrate to the front surface of the photovoltaic panel, and the penetrated glue needs to be cleaned, increasing the complexity of installation. In this case, a pressure relief area 1h is designed. This pressure relief area 1h is not coated with glue but is used to provide a storage space for the glue when it is squeezed and flows, and by designing such an area, the excess glue is absorbed to prevent the glue from penetrating to the surface of the photovoltaic panel. Since the glue is a fluid, when coated on a vertical plane, it is very easy to flow downward due to the gravity of the glue itself, resulting in the situation that the glue needs to be cleaned and reapplied. In this case, to solve such a problem, the side of the glue application area 1g close to the pressing block 2 is designed into a wavy shape, which increases the adhesion area of the glue and reduces the likelihood of the glue flowing downward before curing. At the same time, the wavy structure has a certain effect similar to a "dam", and the glue flow is blocked by the protrusions, reducing the amount and speed of the glue flowing downward.

[0034] Specifically, a first connection groove 1k is provided on the side of the first side plate 1a close to the upper support plate 1d, and a first seal 1m is provided in the first connection groove 1k. A second seal 1n is provided at one end of the upper support plate 1d away from the first side plate 1a. The first seal 1m and the second seal 1n are made of any one of rubber material and silica gel material, and the first seal 1m is connected to the first connection groove 1k by an interference fit.

[0035] In this embodiment, the designed first seal 1m and second seal 1n are both to prevent hard contact between the photovoltaic panel and the frame, avoiding the situation that the photovoltaic panel is easily damaged due to hard contact. When connecting the first seal 1m with the photovoltaic panel, it can be selected that the side of the photovoltaic panel directly abuts against the first seal 1m, or it can also be connected by using double-sided tape or glue between the two. Similarly, when connecting the second seal 1n with the lower surface of the photovoltaic panel, it can be connected by using double-sided tape or glue adhesion. The connection between the second seal 1n and the upper support plate 1d here can be connected by a slot and block connection method, or can also be connected by double-sided tape or glue, ultimately achieving the purpose of fixing the second seal 1n on the upper surface of the upper support plate 1d.

[0036] Specifically, the briquetting member 2 further includes an upper top plate 2b, a lower top plate 2c, and a locking bottom plate 2d. The upper top plate 2b, the lower top plate 2c, the locking bottom plate 2d, and the briquetting 2a are of an integrally formed structure. The overall height of the briquetting member 2 is not greater than the overall height of the frame member 1. When the briquetting member 2 is used to fixedly install the frame member 1, the locking bottom plate 2d is fixed on the photovoltaic support by the cooperation connection mode of bolts and nuts.

[0037] In this embodiment, when the briquetting member 2 is used to install the frame member 1 on the photovoltaic support, the sides of the upper top plate 2b and the lower top plate 2c abut against the first side plate 1a, and the briquetting 2a is engaged in the engaging groove 1e and fixed by means of a locking bolt. During the locking process, the frame member 1 receives a downward pulling force from the briquetting 2a, thereby achieving the purpose of fixing the frame member 1. And the height of the entire briquetting member 2 is designed to be not greater than the height of the frame member 1, which can ensure that there are no protrusions around the photovoltaic panel after the frame member 1 is fixedly installed on the photovoltaic support, effectively ensuring the flow of rainwater, and ensuring the efficiency of rainwater washing away the dust, debris or snow on the photovoltaic panel, so as to achieve the purpose of preventing dust and snow accumulation.
