Detailed Description

The preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making clear and defining the scope of the present utility model.

Referring to fig. 1 and 2, the implementation contents of the embodiment of the present utility model include:

the narrow frame for the photovoltaic module is a rectangular frame formed by splicing two long frames 1 with the same specification and two short frames with the same specification, water falling holes 101 are arranged on the long frames 1 and the short frames to prevent water accumulation, the splicing angle between the long frames 1 and the short frames is 45 degrees, the cross section structures of the long frames 1 and the short frames are the same, the narrow frame comprises side plates 102, an inner connecting plate 103, a front pressing plate 106, an inner partition plate 105 and a back pressure plate 104, and the actual thickness of the parts of the side plates 102, the inner connecting plate 103, the front pressing plate 106, the inner partition plate 105 and the back pressure plate 104 is generally 1.3-1.5 mm; the side plates 102, the front pressing plate 106, the inner connecting plate 103 and the inner partition plate 105 together enclose a rectangular connecting cavity 108 with the periphery closed, inner convex lines 107 are arranged on the upper side and the lower side of the connecting cavity 108, the part of the front pressing plate 106 exceeding the connecting cavity 108 forms a battery pressing edge of the narrow-edge frame for the photovoltaic module, the part of the inner partition plate 105 exceeding the connecting cavity 108 forms a partition belt, the battery pressing edge, the partition belt and the inner connecting plate 103 together enclose a panel mounting groove with one side opened, and the side plates 102, the inner partition plate 105 and the back pressure plate 104 together enclose a back pressure plate mounting groove 109. The photovoltaic module is connected with the adjacent long frames 1 and short frames by using right-angle positioning angle codes 2 in the narrow-side frames, two mutually perpendicular connecting arms 201 of the right-angle positioning angle codes 2 respectively extend into connecting cavities 108 of the long frames 1 and the short frames during splicing, the design width of a battery pressing edge of the narrow-side frames for the photovoltaic module is between 5mm and 8mm, the actual width is generally about 6mm, 2 friction lines 1011 are arranged on the inner sides of the battery pressing edges, the width of a separation belt is generally 2 mm to 4mm, and one friction line 1011 is also arranged on the inner sides of the separation belt. Through the above mode, when photovoltaic module assembles, solar photovoltaic panel joint is in the panel mounting groove, the backplate joint is in backplate mounting groove 109, and the centre is separated by the dividing strip, leaves sizing material overflow space, because the inboard on battery blank holder and dividing strip has all used friction line 1011, has effectively improved the total frictional force between photovoltaic panel both sides surface and battery blank holder and the dividing strip to under the condition that area of contact reduces because the battery blank holder width reduces between battery blank holder and photovoltaic panel, guarantee the centre gripping stability of photovoltaic panel.

The design height of the friction lines 1011 on the separation belt and the friction lines 1011 on the battery pressing side is 0.5mm. Because the friction lines 1011 are too low without friction effect, if the height is too large, the gap between the battery edge and the photovoltaic panel is too large, which affects the stability of the installation.

The back pressure plate 104 has a width close to the width of the inner partition 105, and is inclined in the direction of the inner partition 105, the inclination angle is 5 to 10 °, and in practical implementation, the inclination angle is generally 8 °. The inclination design is because the backboard is heavier and has a tendency to fall outwards under the action of gravity, and the adoption of the inclination design can prevent the back pressure board 104 from deforming outwards under the condition that the back pressure board is continuously stressed and pressed downwards by gravity, so that the backboard falls off. The top of back pressure board 104 is provided with cushion chamber 1010 towards interior baffle 105 direction, through setting up cushion chamber 1010, has increased the elastic restoring force of back pressure board 104, because only cushion chamber 1010 both sides and backplate contact moreover, the pressure of contact position is high, and frictional force is big, can further prevent that the backplate from droing.

The connecting arm 201 of the right-angle positioning angle code 2 is of a hollow frame structure, the height of the connecting arm 201 is in clearance fit with the upper side and the lower side of the connecting cavity 108, so that the connecting arm 201 is conveniently inserted into the connecting cavity 108, and the connecting cavity 108 is also provided with inner convex lines 107 on the upper side and the lower side, so that a good pressing effect can be achieved. The width of the connecting arm 201 is in interference fit with the inner and outer sides of the connecting cavity 108. A pawl structure is mounted on the inner side of the connecting arm 201. The reason that the right angle positioning angle code 2 adopts the hollow frame structure is that the hollow frame structure has certain elasticity, and in the connecting cavity 108 that inserts interference fit through the mode of deformation like this, can make the back tooth press on the inside wall of connecting cavity again with elasticity after inserting, improve connection stability, prevent to drop.
