Description

Technical Field

[0001] The utility model relates to the technical field of solar photovoltaic modules, in particular to a solar frame resistant to impact. Background Art

[0002] The solar frame is used to fix the solar cells so that the solar cells can be installed on the roof.

[0003] Chinese Patent CN217508682U discloses a profile for a photovoltaic module frame and a photovoltaic module frame, including a profile. A U-shaped notch is provided at the upper part of the profile for installing and clamping a solar panel, and a rectangular cavity is provided at the lower part for clamping an angle code to realize the connection and fixation of the long frame and the short frame.

[0004] Since the bottom of the notch is composed of only one plate, when an external force impacts the outside of the bottom of the notch, the impact force is easily directly transmitted to the solar panel, resulting in damage to the solar panel.

[0005] Therefore, how to prevent the solar panel from being damaged when the outside of the profile is impacted has become an urgent problem to be solved by those skilled in the art. Summary of the Utility Model

[0006] To solve the technical problems in the background art, the utility model discloses a solar frame resistant to impact.

[0007] The utility model provides a solar frame resistant to impact, including a frame body. A U-shaped card slot is provided at the upper part for clamping a photovoltaic panel, and a card hole is provided at the lower part for clamping an angle code. A buffer cavity is also provided at the opening position of the frame body facing away from the card slot;

[0008] The buffer cavity is provided with a first outer plate; the first outer plate is opposite to the bottom of the card slot;

[0009] The first outer plate is arc-shaped and concave towards the card slot.

[0010] The setting of the buffer cavity enables the first outer plate to play a buffering role when being impacted, and will not directly act on the photovoltaic panel, thereby reducing the impact force on the photovoltaic panel and avoiding damage caused by direct impact; the arc-shaped design of the first outer plate enables the upper and lower ends of the first outer plate to become the stress points when being impacted. When the upper end of the first outer plate is stressed, the force will be transmitted to the upper slot wall of the card slot. When the lower end of the first outer plate is stressed, the force will be transmitted to the lower slot wall of the card slot, thereby avoiding the direct stress on the bottom of the card slot and reducing the stress on it.

[0011] The card hole is provided with a second outer plate; the upper end of the second outer plate is connected to the lower end surface of the first outer plate; when the second outer plate is impacted, the stress area is large, resulting in easy deformation of the card hole. Based on this, a further improvement lies in that the second outer plate is arc-shaped and recessed toward the inner side of the card hole.

[0012] Due to the low structural strength of the card hole, based on this, a further improvement lies in that the opposite side of the card hole located on the second outer plate is set as the second inner plate; a reinforcing plate is connected to the central positions of the second outer plate and the second inner plate; the reinforcing plate divides the card hole into an upper side hole and a lower side hole.

[0013] To further improve the structural strength of the frame body, specifically: the inner side surfaces of the upper side holes are arched toward the central positions of the upper side holes; the inner side surfaces of the lower side holes are arched toward the central positions of the lower side holes. The arched settings of the inner walls of the upper side holes and the lower side holes are also used for corner code clamping and positioning, making the corner code clamping more stable and the structure of the solar energy frame more stable.

[0014] The specific structure of the frame body is: including a top plate, a middle plate, and a bottom plate that are arranged in parallel and at intervals from top to bottom; the upper end of the first outer plate is connected to one end of the top plate, and the lower end is connected to one end of the middle plate; a baffle is vertically connected to the middle parts of the top plate and the middle plate, so that the baffle, the part of the top plate and the middle plate on one side of the baffle, and the first outer plate form a buffer cavity; the part of the baffle, the top plate, and the middle plate on the other side of the baffle forms a card slot; the upper end of the second outer plate is connected to one end of the middle plate, and the lower end is connected to one end of the bottom plate; the upper end of the second inner plate is connected to the other end of the middle plate, and the lower end is connected to the other end of the bottom plate.

[0018] Now the present invention will be further described in detail in conjunction with the drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so they only show the components related to the present invention.

[0019] The present invention discloses an impact-resistant solar energy frame, including a frame body 1. As Figure 1As shown in the figure, the frame body 1 is successively provided with a top plate 11, a middle plate 12, and a bottom plate 13 which are arranged side by side and at intervals from top to bottom. Taking the front view as a reference, the left ends of the top plate 11 and the middle plate 12 are connected to a first outer side plate 5, the left ends of the middle plate 12 and the bottom plate 13 are connected to a second outer side plate 6, and the lower end of the first outer side plate 5 is connected to the upper end of the second outer side plate 6. The right ends of the middle plate 12 and the bottom plate 13 are connected to a second inner side plate 7. Figure 1 A baffle 14 is vertically connected to the middle part between the top plate 11 and the middle plate 12, so that the baffle 14, the part of the top plate 11 and the middle plate 12 on the left side of the baffle 14, and the first outer side plate 5 form a buffer cavity 4. The part of the baffle 14, the top plate 11 and the middle plate 12 on the right side of the baffle 14 forms a U-shaped card slot 2 for clamping a photovoltaic panel. The middle plate 12, the second inner side plate 7, the bottom plate 13 and the second outer side plate 6 form a card hole 3 for clamping an angle code.

[0020] The setting of the buffer cavity 4 enables the first outer side plate 5 to play a buffering role when being impacted, and will not directly act on the photovoltaic panel, thereby reducing the impact force received by the photovoltaic panel and avoiding damage caused by direct impact.

[0021] Among them, the first outer side plate 5 is arc-shaped and concave towards the inside of the buffer cavity 4. With such a setting, when the first outer side plate 5 is impacted, its upper and lower ends become the stress points; when the upper end of the first outer side plate 5 is stressed, the force will be transmitted to the upper groove wall of the card slot 2, and when the lower end of the first outer side plate 5 is stressed, the force will be transmitted to the lower groove wall of the card slot 2, thereby avoiding the direct stress on the bottom of the card slot 2 and reducing the stress on it.

[0022] The second outer side plate 6 is also arc-shaped and concave towards the inside of the card hole 3. With such a setting, the stress area on the outer side of the second outer side plate 6 can be reduced. When the second outer side plate 6 is impacted by an external object, the upper and lower ends of the second outer side plate 6 are likely to become the stress points, thereby protecting the card hole 3 from being deformed easily.

[0023] A reinforcing plate 8 is connected to the central positions of the second outer side plate 6 and the second inner side plate 7; the reinforcing plate 8 divides the card hole 3 into an upper side hole 31 and a lower side hole 32, and one end of the angle code is also divided into two parts, which are respectively clamped into the upper side hole 31 and the lower side hole 32. The setting of the reinforcing plate 8 makes the structure of the card hole 3 more stable, and can also ensure that the card hole 3 is not easily deformed when the position between the two ends of the second outer side plate 6 is impacted.

[0024] The upper side wall, the lower side wall and the right side wall of the upper side hole 31 are all arc-shaped and arched towards the center position of the upper side hole 31; the upper side wall, the lower side wall and the right side wall of the lower side hole 32 are also all arc-shaped and arched towards the center position of the lower side hole 32. With such a setting, the thickness of the middle plate 12, the reinforcing plate 8, the bottom plate 13 and the second inner side plate 7 is increased, which not only improves the structural stability of the card hole 3, but also improves the structural strength of the frame body 1.
