Description

Technical Field

[0001] The utility model relates to the field of solar frame profiles, in particular to a photovoltaic frame profile connector and a photovoltaic frame. Background Art

[0002] As a new energy source, solar energy is increasingly being used. Currently, the main way to utilize solar energy is to convert it into electrical energy with the help of photovoltaic panels. Therefore, the installation of photovoltaic panels is the basic condition for collecting solar energy.

[0003] The installation of photovoltaic panels needs to rely on the corresponding supporting structure. In addition to the base frame, as the lateral limit and protection of the photovoltaic panels, it is necessary to cover the outer side of the assembled photovoltaic panel array with a frame. In order to facilitate transportation, the current frames are mostly made in the form of long strips of profiles, which are cut and combined into rectangular frames according to needs. The frame profiles prepared by the commonly used composite material pultrusion process have weak lateral strength. The installation method of connecting and assembling by drilling holes and attaching bolts will damage the frame strength and affect the service life. The installation process is more complicated and prolongs the outdoor working time of the staff. The adhesive connection method, on the one hand, cannot immediately achieve the optimal connection strength, and on the other hand, it is easy to generate new pollution. Utility Model Content

[0043] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0044] Example 1

[0045] See also Figure 1-Figure 3 , this application provides the following technical solutions:

[0046] A photovoltaic frame profile connector, the connector is a bent structure as a whole, and is arranged in a right-angled shape; the connector is an integrally formed structure, and for the convenience of explaining the structural part, its components are divided into a first connector 1 and a second connector 2. The first connector 1 is one half of the bent structure of the connector; one end of the first connector 1 is a first insertion portion 11, and the other end is a first connection portion 12; the second connector 2 is the other half of the bent structure of the connector; one end of the second connector 2 is a second insertion portion 21, and the other end is a second connection portion 22. The first connector 1 and the second connector 2 are fixedly connected by the first connection portion 12 and the second connection portion 22, and the connection between the first connection portion 12 and the second connection portion 22 is arranged in a right angle; the first insertion portion 11 and the second insertion portion 21 can be connected to two adjacent frame profiles of the photovoltaic frame respectively.

[0047] When in use, the first connector 1 and the second connector 2 are plugged and connected to the two frame profiles of the photovoltaic frame respectively; the frame profile is clamped by the clamping structure 3 set on the first connector 1 and the second connector 2, thereby completing the combined connection between the frame profile and the connector.

[0048] The snap-fit ​​structure 3 of the first connector 1 is arranged between the first insertion portion 11 and the first connection portion 12; the snap-fit ​​structure 3 of the second connector 2 is arranged between the second insertion portion 21 and the second connection portion 22. For the convenience of explanation, the side facing the inside of the photovoltaic frame in the use state of this connector is the inner side, and the side facing the outside of the photovoltaic frame is the outer side; that is, the rectangular frame formed after the photovoltaic frame is spliced ​​is formed, with the side facing the photovoltaic panel as the inner side, and the opposite side as the outer side. This solution adopts a setting method in which the snap-fit ​​structure 3 is arranged on the inner side of the first connector 1 and the second connector 2. According to actual needs, the snap-fit ​​structure 3 can also be arranged on the outer side of the connector.

[0049] The clamping structure 3 includes an outer clamping plate 31, an inner clamping plate 32 and a clamping slot 33. The outer clamping plate 31 and the inner clamping plate 32 are provided one each and are both provided in an inclined shape. Figure 3 For example, Figure 3 The inner sides of the outer card plate 31 and the inner card plate 32 on the first connecting body 1 are inclined toward the direction of the first connecting portion 12, that is, Figure 3 The upper sides of the outer card plate 31 and the inner card plate 32 of the first connector 1 are inclined toward the left. The inner sides of the outer card plate 31 and the inner card plate 32 on the second connector 2 are inclined toward the direction of the second connecting portion 22, that is, Figure 3 The right sides of the outer clamping plate 31 and the inner clamping plate 32 of the second connector 2 are tilted downward. Through this structural setting, the outer clamping plate 31 and the inner clamping plate 32 of the clamping structure 3 form a barb-like structure, and the direction of the barb corresponds to the plug-in direction of the frame profile. During the insertion and connection process, the inner and outer clamping plates will not form an obstruction. When you want to pull it apart, it will be stuck on the inner side of the frame profile to prevent the connector and the frame profile from separating.

[0050] The card slot 33 is a groove formed on the inner side of the first connector 1 and the second connector 2; the outer card plate 31 is arranged outside the card slot 33. Taking the first connector 1 as an example, the lower edge of the outer card plate 31 is connected to the corner of the card slot 33 near the first insertion portion 11. In other words, the lower edge of the outer card plate 31 is arranged at the card slot 33. Figure 3 The outer card plate 31 is located at the upper right corner. This position can bring better strength to the outer card plate 31. The inner card plate 32 is arranged inside the card slot 33, and the lower edge of the inner card plate 32 is fixedly connected to the bottom of the card slot 33; the upper edges of the outer card plate 31 and the inner card plate 32 are located on the same horizontal line, so the overall length of the inner card plate 32 is longer than that of the outer card plate 31.

[0051] The outer clamping plate 31 , the inner clamping plate 32 and the clamping slot 33 on the second connecting body 2 are arranged in a similar manner to the first connecting body 1 , and will not be described in detail herein.

[0052] A first fitting structure 4 is also provided on the side of the first connector 1 and the second connector 2 opposite to the clamping structure 3. In the present embodiment, the first fitting structure 4 is a planar structure that can fit in contact with the inner side of the frame profile.

[0053] As for the specific structural form of the frame profile corresponding to the clamping structure 3, the existing structure can be adopted, such as setting a clamping block, a clamping groove, etc. corresponding to the outer clamping plate 31 and the inner clamping plate 32 on the inner wall of the frame profile. It is only necessary to meet the requirement that when the connecting member is inserted into the inner part of the frame profile, this structure can compress the outer clamping plate 31 and the inner clamping plate 32 respectively to deform them, and when bypassing this structure, the outer clamping plate 31 and the inner clamping plate 32 are reset to form a clamping connection.

[0054] Example 2

[0055] See also Figures 4 to 6, based on the above embodiment, different from the above embodiment, the first fitting structure 4 is a wavy structure. The first fitting structure 4 is arranged on the outer side of the first connector 1 and the second connector 2, and a second fitting structure 5 is also arranged corresponding to the first fitting structure 4. The second fitting structure 5 is arranged on the first connector 1 and the second connector 2; the second fitting structure 5 on the first connector 1 is located between the first insertion part 11 and the corresponding snap-fit ​​structure 3; the second fitting structure 5 on the second connector 2 is located between the second insertion part 21 and the corresponding snap-fit ​​structure 3, and the second fitting structure 5 is also a wavy structure.

[0056] The first fitting structure 4 and the second fitting structure 5 are provided to enhance the friction between the connector and the inner wall of the frame profile, thereby making the connection between the two more secure.

[0057] Example 3

[0058] Based on the above implementation scheme, see Figure 3 and Figure 6 The first connector 1 and the second connector 2 are provided with a plurality of through holes, and reinforcing ribs are arranged in the through holes, so that the weight can be reduced and the toughness can be improved while ensuring sufficient strength.

[0059] In addition, the first insertion portion 11 of the first connector 1 and the second insertion portion 21 of the second connector 2 are both pointed structures, which are convenient for insertion into the frame profile. In order to ensure the safety of the workpiece, the ends of the first insertion portion 11 and the second insertion portion 21 are both provided with a plane structure to reduce the possibility of unilateral injury to the staff due to the tip. The plane structure of the end of the second insertion portion 21 has a larger area than the plane structure of the end of the first insertion portion 11. In other words, the end of the second insertion portion 21 is not as "sharp" as the end of the first insertion portion 11, but appears to be more "bulky". The formation of this "bulky" end is that the end of the second connector 2 is "cut" a certain distance compared to the first connector 1, so that its end is slightly shorter than the first connector 1.

[0060] Because it is considered that when the connector is combined with the frame profile, the profiles on both sides will basically not be connected at the same time, but will be connected one by one. In the process of forming the overall frame, the last connector that is connected and formed as the four corners is slightly more difficult to install than the previous ones. The first insertion part 11 and the second insertion part 21 with unequal lengths and slightly different structures are used. Considering this situation, the longer first connector 1 can be plugged in first, and then the second connector 2 can be plugged in. The improvement of this structure can reduce the difficulty of plugging in at this time.

[0061] Example 4

[0062] On the basis of the above implementation scheme, this scheme also provides a photovoltaic frame, using the above connectors and frame profiles. A single frame profile is a long strip structure, which can be made of composite materials, such as aluminum alloy, and is hollow inside to form a corresponding connector plug hole, which can be plugged with the connector; at least four frame profiles are provided, and the frame profiles can be assembled into a rectangular frame through the connector.
