Description

Technical Field

[0001] This technical solution relates to the field of photovoltaic bracket technology, and specifically refers to a unidirectional universal adjustment device for photovoltaic brackets. Background Technology

[0002] A photovoltaic (PV) bracket is a support structure designed for placing, installing, and fixing solar panels in a solar photovoltaic power generation system. During installation, universal connectors are used to assist in adjustment to adapt to different terrain slopes.

[0003] For example, Chinese patent CN210068723U discloses a universal connector for a photovoltaic bracket, including a first connecting shaft, a connecting through hole, a first hinge, a second hinge, a connecting protrusion, a second connecting shaft, a first universal bearing, a second universal bearing, and a third universal bearing. The second universal bearing is designed inside the first connecting shaft. By connecting the first and second steering shafts to the first and second hinges, moving the second connecting shaft causes the shaft to rotate, thereby allowing the second connecting shaft to move left and right. See [link to relevant documentation]. Figure 2 The existing photovoltaic support system has a mounting column 100 and a transmission link 200. A reducer 300 is mounted on the mounting column 100. The reducer 300 has a shaft 400. A universal adjustment device can be connected between the transmission link 200 and the shaft 400.

[0004] The aforementioned universal connectors for photovoltaic brackets have a high cost due to the large number of components used in existing connectors, which also leads to complex installation procedures and inconvenience during use. They are troublesome to use and need to be improved. Summary of the Invention

[0005] To address the problem of complex installation and cumbersome use of universal connectors, this technical solution provides a unidirectional universal adjustment device for photovoltaic brackets.

[0006] The purpose of this technical solution is achieved as follows:

[0007] A photovoltaic bracket unidirectional universal adjustment device includes a connecting body, the connecting body including two shaft fixing parts, each of the two shaft fixing parts having a fixing groove on its opposite side end face, the two fixing grooves being perpendicular to each other in their through direction, the shaft fixing parts having shaft holes, the shaft holes corresponding to the opposite side walls of the fixing grooves.

[0008] With the above technical solution, when the photovoltaic bracket unidirectional universal adjustment device is in normal use, the shaft fixing parts on both sides are interconnected and fixed. The two parts to be connected are respectively embedded into the fixing grooves of the two shaft fixing parts. The connecting piece passes through the shaft hole and connects to the corresponding part, realizing a stable hinge connection between it and the corresponding shaft fixing part. Since the through direction of the two fixing grooves is perpendicular to each other, the two parts can rotate relative to each other along the fixing groove in two orthogonal directions, respectively, to adjust the angle, satisfying the error adaptability of a certain angle in both directions. When the slope of the installation terrain is inconsistent, the corresponding installation angle can be adjusted, improving the applicability of complex terrain and enhancing the installation adjustment capability, thereby simplifying the installation process and making installation and use more convenient.

[0009] Preferably, the opposite side walls of the fixing groove are thin-walled and have elastic portions.

[0010] Through the above technical solution, the thin-walled design of the elastic part allows the elastic parts on both sides to deform under pressure when the connector is tightened. The elastic parts on both sides can move closer to the opposite sides of the component in the connecting groove, reducing the excess space between the hinged component and the elastic parts on both sides, and restricting the component from swinging and shifting along the hinge axis, thereby improving the connection stability.

[0011] Preferably, the elastic part protrudes toward the fixing groove to form an abutting surface, the shaft hole is located on the abutting surface, and the abutting surfaces on both sides are close together to form surface contact.

[0012] With the above technical solution, when the elastic parts on both sides approach each other, the contact surfaces on both sides first contact the parts to be connected, reducing the deformation required for the elastic parts to clamp the parts, ensuring that the deformation range of the elastic parts is within a reasonable range, so as to avoid damage or failure caused by excessive deformation, and improve durability. At the same time, the contact surface is an arc surface protruding towards the fixing groove, which prevents the pressure from being too low due to the reduced contact area between the elastic parts and the parts caused by bending. The contact surface forms a stable surface contact, which provides a more uniform and stable clamping effect.

[0013] Preferably, the contact surfaces on both sides fit together such that the fixing groove is flared outwards in the direction away from the contact surfaces.

[0014] The above technical solution, based on the fact that the contact surface is curved, has the curved guide fixing groove on one side of the two contact surfaces near the groove opening flared outwards in the direction away from the highest point of the contact surface, which improves the convenience and smoothness of fitting the fixing groove with the corresponding component.

[0015] Preferably, a connecting portion is integrally formed between the two shaft fixing parts.

[0016] The above technical solution, by designing the two shaft fixing parts as a single unit, ensures that the connecting part replaces the seam and connection point between the two shaft fixing parts. The integrated design enhances the strength of the structure and simplifies the processing flow.

[0017] Preferably, the two shaft fixing parts are respectively formed with two sets of elastic parts, the two sets of elastic parts are arranged perpendicular to each other, and each elastic part is integrally formed on the connecting part.

[0018] With the above technical solution, each fixing spring is integrally formed on the connecting part. This structure further enhances the overall strength and rigidity, reduces performance degradation and safety hazards caused by loosening of parts after long-term use, and the stamping process simplifies the manufacturing process, reduces production costs and cycle time, and improves production efficiency.

[0019] The key and beneficial technical effects of this technical solution compared to existing technologies are:

[0020] 1. This technical solution embeds the components to be connected one by one into the fixing grooves of the two shaft fixing parts, and achieves a stable hinge connection with the corresponding components by the connecting piece passing through the shaft hole. The two components can be rotated relative to each other in two orthogonal directions (horizontal or vertical) along the fixing groove to adjust the angle. The installation angle can be adjusted to adapt to different terrains and angles, making installation and use more convenient.

[0021] 2. This technical solution forms a contact surface by bending the elastic part towards the fixing groove, and the inclined surface is an arc surface that protrudes towards the fixing groove. When the elastic parts on both sides bend and approach each other, the contact surfaces on both sides form a stable surface contact with the corresponding parts, thus providing a more uniform and stable clamping effect.

[0026] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings.

[0027] Example:

[0028] See Figure 1 A photovoltaic bracket unidirectional universal adjustment device includes a connecting body 1, which includes two shaft fixing parts 11. A connecting part 2 is integrally formed between the two shaft fixing parts 11. Each shaft fixing part 11 has a fixing groove 3. The two fixing grooves 3 are correspondingly opened on the opposite end faces of the two shaft fixing parts 11. The through direction between the two fixing grooves 3 is perpendicular to each other. The bottom of the two fixing grooves 3 corresponds to the opposite end face of the connecting part 2. Alternatively, a connecting member can be provided between the two shaft fixing parts 11. When the connecting member is tightened, the two shaft fixing parts 11 are firmly fixed. When the connecting member is removed, the two shaft fixing parts 11 are separated.

[0029] Each fixing groove 3 has elastic portions 5 formed on its opposite two side walls. The elastic portions 5 on both sides are thin-walled. One end of each elastic portion 5 is integrally formed on the connecting portion 2. The two shaft fixing portions 11 are correspondingly formed with two sets of elastic portions 5. The distribution direction of one set of elastic portions 5 is perpendicular to the distribution direction of the other set of elastic portions 5. In this example, the four connecting portions 2 are arranged one-to-one on the four corresponding sides of the connecting portion 2 along the circumferential direction.

[0030] Each elastic part 5 has a contact surface 6, which is formed by bending the elastic part 5 toward the fixing groove 3, so that the contact surface 6 protrudes toward the fixing groove 3. Each shaft fixing part 11 has a shaft hole 4, which corresponds to the opposite side wall of the fixing groove 3. The shaft hole 4 is specifically set on the contact surface 6. When the connector is aligned and passes through the shaft hole 4, the connector passes through the transmission link 200 or the shaft 400 at the same time. The connector provides the hinge axis and tightens the connector, so that the contact surfaces 6 on both sides are deformed and pressed against the opposite side wall of the transmission link 200 or the shaft 400, so that the shaft fixing part 11 forms a surface contact positioning of the connecting parts. After the connector is tightened or loosened, the transmission link 200, the shaft 400 and the connecting body 1 can adjust the angle relative to each other along the hinge axis. This embodiment shows the case where the adjustment angle meets at least 15° in both directions.

[0031] The slope of the two contact surfaces 6 away from the bottom of the fixing groove 3 cooperates with each other, so that the two contact surfaces 6 are inclined to the fixing groove 3 opening outward through the slope.

[0032] See Figure 2 and Figure 3The connecting body 1 is located between the reducer 300 and the transmission connecting rod 200. The transmission connecting rod 200 and the shaft 400 are respectively embedded into the two fixing slots 3. The transmission connecting rod 200 has a through hole 1 and the shaft 400 has a through hole 2. The through direction of the through hole 1 is aligned with the shaft hole 4 of one end of the shaft fixing part 11, and the through direction of the through hole 2 is aligned with the shaft hole 4 of the other end of the shaft fixing part 11. A pin passes through the shaft hole 4 and the through hole. The pin is tightened until the elastic parts 5 on both sides deform and approach the opposite end faces of the transmission connecting rod 200 and the shaft 400 to form a clamp, so that the contact surface 6 abuts against the corresponding end face of the corresponding component to form a stable positioning.

[0033] The specific work process of this plan is as follows:

[0034] This technical solution involves stamping the elastic parts 5 arranged circumferentially along the side of the connecting part 2, bending the relatively distributed elastic parts 5 to the same side of the connecting part 2, with the bending directions of the two sets of elastic parts 5 being opposite, thus forming two shaft fixing parts 11. The two connecting components are respectively embedded into the fixing grooves 3 of the two shaft fixing parts 11. A stable hinge is achieved by the connecting parts passing through the shaft holes 4 and the corresponding components. Based on the fact that the through directions of the two fixing grooves 3 are perpendicular to each other, the two connecting components can be adjusted by rotating along the fixing grooves 3 in two orthogonal directions, respectively, to meet the error adaptability of at least 15° in both directions. This allows for adjustment of the corresponding installation angle under different installation terrains, improving the applicability to complex terrains and enhancing the installation adjustment capability, thereby simplifying the installation process and making installation and use more convenient.
