[0002] A photovoltaic tracking bracket is generally composed of several parts, including a bracket support system, a rotating mechanism and a photovoltaic module. The rotating mechanism is composed of main components such as a rotating bearing seat, a main shaft support, a column top seat and a plastic bearing. Plastic bearings are usually used in pairs and are installed on the upper and lower parts of the main shaft to support the main shaft. At the same time, in order to prevent the plastic bearing from falling out when the tracking bracket rotates, one end of the bearing boss will be pressed against the rotating bearing seat, and the other end will be fixed with a bearing baffle to prevent the bearing from falling out.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0045] Reference below Figure 1-Figure 14 A self-locking bearing structure 100 according to the present embodiment is described.
[0046] like Figure 1-Figure 14 As shown, according to the self-locking bearing structure 100 of this embodiment, the self-locking bearing structure 100 can be installed on the bearing seat 200, the bearing seat 200 has a center line, and the self-locking bearing structure 100 can rotate relative to the bearing seat 200 around the center line, wherein a main shaft 400 can be penetrated in the self-locking bearing structure 100, and the extension direction of the main shaft 400 is the extension direction of the center line of the bearing seat 200 (such as Figure 1 The left and right directions shown are the same, and the rotation of the main shaft 400 can drive the self-locking bearing structure 100 to rotate relative to the bearing seat 200.
[0047] The self-locking bearing structure 100 includes: a first split body 10 and a second split body 20, the first split body 10 has a first limiting boss 11, and the first limiting boss 11 can contact the bearing seat 200 to limit the first split body 10 from moving into the bearing seat 200, and prevent the first split body 10 from being separated from the bearing seat 200 due to passing through the bearing seat 200; the second split body 20 has a second limiting boss 21, and the second limiting boss 21 can contact the bearing seat 200 to limit the second split body 20 from moving into the bearing seat 200, and prevent the second split body 20 from being separated from the bearing seat 200 due to passing through the bearing seat 200.
[0048] Among them, after the first split body 10 extends into the bearing seat 200, the second split body 20 can extend into the bearing seat 200 and lock with the first split body 10, or, after the second split body 20 extends into the bearing seat 200, the first split body 10 can extend into the bearing seat 200 and lock with the first split body 10, so that the self-locking of the self-locking bearing structure 100 can be achieved to prevent the first split body 10 from being separated from the second split body 20, thereby preventing the first split body 10 and the second split body 20 from moving in directions away from each other to be separated from the bearing seat 200 respectively, thereby improving the limiting effect of the self-locking bearing structure 100 and preventing the self-locking bearing structure 100 from being separated from the bearing seat 200.
[0049] Specifically, along the extension direction of the center line (such as Figure 1 The first split body 10 can be moved from one end of the bearing seat 200 (as shown in the left and right directions). Figure 1 The left end shown in the figure) extends into the bearing seat 200, and after the first split body 10 extends into the bearing seat 200, the first limiting boss 11 and the left side of the bearing seat 200 (as shown in the figure) are connected. Figure 1 The left side shown in the figure) contacts to limit the first split body 10 from moving to the right (as shown in the figure) Figure 1 The second split body 20 can be moved from the other end of the bearing seat 200 (as shown in the left to right direction). Figure 1 The second limiting boss 21 can be aligned with the right side of the bearing seat 200 (as shown in the right end) after the second split body 20 is extended into the bearing seat 200. Figure 1 The first split body 10 contacts the right side of the first split body 10 to limit the first split body 10 from moving leftward (as shown in FIG. Figure 1 right to left direction as shown).
[0050] Furthermore, after the first sub-body 10 and the second sub-body 20 are respectively extended into the bearing seat 200, the first sub-body 10 can be locked with the second sub-body 20 to limit the first sub-body 10 from moving leftward (such as Figure 1 The second split body 20 is restricted from moving to the right (as shown in the right to left direction) and Figure 1The self-locking bearing structure 100 can be moved in the extension direction of the center line of the bearing seat 200 (as shown in the left to right direction). Figure 1 The self-locking bearing structure 100 is limited in the left and right directions (as shown) to prevent the self-locking bearing structure 100 from being separated from the bearing seat 200.
[0051] According to the self-locking bearing structure 100 of the present embodiment, by providing a self-locking first split body 10 and a second split body 20, and the first split body 10 and the second split body 20 respectively have a limiting boss, so that the first split body 10 and the second split body 20 can be locked and matched when the limiting boss limits them, so as to prevent the first split body 10 from being separated from the second split body 20. Therefore, on the basis of preventing the first split body 10 or the second split body 20 from passing through the bearing seat 200 and separating from the bearing seat 200, the first split body 10 and the second split body 20 can be prevented from moving in a direction away from each other and separating from the bearing seat 200, which can improve the limiting effect of the self-locking bearing structure 100 and prevent the self-locking bearing structure 100 from being separated from the bearing seat 200; and compared with the technical solution of providing a bearing baffle on the outside of the plastic bearing to limit the plastic bearing, the number of components can be reduced, the cost can be reduced, and the installation is convenient.
[0052] like Figure 2 As shown, in some embodiments, the side of the first split body 10 facing the second split body 20 (such as Figure 2 The lower side shown in FIG. 1 may have a mating portion, and the side of the second sub-body 20 facing the first sub-body 10 (such as Figure 2 The upper side shown in the figure may have a connecting portion, which may cooperate with the matching portion to lock the first sub-body 10 and the second sub-body 20, thereby realizing the self-locking of the self-locking bearing structure 100 and preventing the first sub-body 10 and the second sub-body 20 from separating.
[0053] like Figure 3 and Figure 4 As shown, in some embodiments, the matching portion may be a limiting protrusion 12, and the connecting portion may be a limiting groove 22. The limiting protrusion 12 matches the shape of the limiting groove 22, and the limiting protrusion 12 can be plugged into and matched with the limiting groove 22, which is beneficial to achieve the locking fit between the first split body 10 and the second split body 20, thereby facilitating the improvement of the limiting effect on the first split body 10 and the second split body 20; or, the matching portion may be a limiting groove 22, and the connecting portion may be a limiting protrusion 12, and the limiting protrusion 12 can be plugged into and matched with the limiting groove 22.
[0054] like Figure 3 and Figure 8As shown, in some embodiments, the limiting protrusion 12 includes: at least one protrusion 121, the number of the protrusion 121 can be one, after the limiting protrusion 12 is plugged into the limiting groove 22, the protrusion 121 can contact the inner wall of the limiting groove 22, which is beneficial to achieving the limiting of the limiting protrusion 12, and is beneficial to the mutual locking of the first sub-body 10 and the second sub-body 20, thereby helping to improve the self-locking effect of the self-locking bearing structure 100.
[0055] Of course, the number of the protrusions 121 can be more, and the multiple protrusions 121 can be arranged along the extension direction of the center line (such as Figure 3 The limiting protrusions 12 are arranged in the left and right directions as shown, and after the limiting protrusions 12 are plugged into the limiting grooves 22, the multiple protrusions 121 can all contact the inner wall of the limiting grooves 22, which can improve the limiting effect of the limiting protrusions 12, and is beneficial to the mutual locking of the first sub-body 10 and the second sub-body 20, thereby helping to improve the self-locking effect of the self-locking bearing structure 100.
[0056] like Figure 3 , Figure 8 and Fig.13 As shown, in some embodiments, the limiting protrusion 12 further includes: a limiting body 122, the limiting body 122 can be extended along the center line (such as Figure 3 The limiting body 122 may be provided on the first split body 10 so that the limiting protrusion 12 is plugged into and matched with the limiting groove 22 of the second split body 20, or the limiting body 122 may be provided on the second split body 20 so that the limiting protrusion 12 is plugged into and matched with the limiting groove 22 of the first split body 10.
[0057] Therefore, by setting a limiting body 122 extending along the extension direction of the center line on the first split body 10 or the second split body 20, and by setting a protrusion 121 on the limiting body 122, it can be ensured that the limiting protrusion 12 is in full contact with the inner wall of the limiting groove 22, which is beneficial to improving the limiting effect of the limiting protrusion 12 and improving the self-locking effect of the self-locking bearing structure 100.
[0058] Specifically, Figure 2 For example, the limiting body 122 can be arranged on the first split body 10, that is, one end of the limiting body 122 (such as Figure 3 The upper end shown in FIG. 10 may be connected to the first split body 10, or the limiting body 122 may be disposed on the second split body 20, that is, one end of the limiting body 122 (such as Figure 3 The lower end shown in FIG. 1 may be connected to the second split body 20; Figure 6 For example, the limiting body 122 can be arranged on the first split body 10, that is, one end of the limiting body 122 (such as Figure 8The right end shown in FIG. 1 may be connected to the first split body 10, or the limiting body 122 may be disposed on the second split body 20, that is, one end of the limiting body 122 (such as Figure 6 The left end shown) can be connected to the second split body 20.
[0059] like Figure 1-Figure 4 As shown, in some embodiments, the first split body 10 and the second split body 20 can be perpendicular to the extension direction of the center line (such as Figure 2 The lower side of the first split body 10 (as shown in the upper and lower directions) is arranged relatively. Figure 3 The lower side of the limit block 12 can be provided with a limit block 12, the limit block 12 includes a limit body 122 and a convex portion 121, the upper end of the limit body 122 (as shown in FIG. Figure 3 The upper end shown in FIG. 1 is connected to the first split body 10, and the protrusion 121 is arranged at the lower end of the limiting body 122 (as shown in FIG. Figure 3 lower end shown).
[0060] There may be multiple protrusions 121, and the limiting body 122 extends along the center line (such as Figure 3 The plurality of protrusions 121 may be arranged in sequence along the extension direction of the limiting body 122, a limiting groove 22 may be provided on the upper side of the second split body 20, the limiting groove 22 matches the shape of the limiting protrusion 12, and the limiting protrusion 12 may be plugged into and matched with the limiting groove 22 to achieve mutual locking of the first split body 10 and the second split body 20.
[0061] Thus, by arranging the first split body 10 and the second split body 20 which are arranged relative to each other along the extending direction perpendicular to the center line, the first split body 10 and the second split body 20 are respectively arranged along the extending direction of the center line (such as Figure 1 By extending the first sub-body 10 and the second sub-body 20 into the bearing seat 200 in the left and right directions as shown, the mutual locking of the first sub-body 10 and the second sub-body 20 can be achieved, and on the basis of achieving the self-locking of the self-locking bearing structure 100, the installation of the self-locking bearing structure 100 can be achieved, which is easy to operate.
[0062] It should be noted that compared with the technical solution of using a double boss bearing (the bearing is divided into an upper part and a lower part, and each part has a boss on the opposite sides), the first split 10 and the second split 20 can be extended into the gap between the main shaft 400 and the bearing seat 200 after the main shaft 400 passes through the middle of the bearing seat 200, so that the first split 10 and the second split 20 are locked with each other. Alternatively, the first split 10 and the second split 20 can be placed in the bearing seat 200 first, so that the first split 10 and the second split 20 are locked with each other, and then the main shaft 400 passes through the middle of the self-locking bearing, which can prevent the self-locking bearing structure 100 from falling during installation and facilitate operation.
[0063] like Figure 5-Figure 14As shown, in some embodiments, the first split body 10 and the second split body 20 can be arranged in the extension direction of the center line (such as Figure 6 The left and right directions shown in FIG. 1 are arranged relatively to each other, and one side of the first split body 10 (such as Figure 8 The left side of the figure can be provided with a limiting protrusion 12, which includes a limiting body 122 and a convex portion 121. The right end of the limiting body 122 (as shown in FIG. Figure 8 The right end as shown in the figure is connected to the first split body 10, and the protrusion 121 can be set on the limiting body 122.
[0064] The limiting body 122 extends along the center line (eg Figure 8 The convex portion 121 may be disposed at the left end of the limiting body 122 (eg, Figure 8 Alternatively, the convex portion 121 may be multiple, and the limiting body 122 extends along the center line (such as Fig.13 The plurality of protrusions 121 may be arranged in sequence along the extending direction of the limiting body 122. The right side of the second split body 20 (such as Fig. 9 A limiting groove 22 may be provided on the right side as shown, and the limiting groove 22 matches the shape of the limiting protrusion 12, and the limiting protrusion 12 may be plugged into and matched with the limiting groove 22 to achieve mutual locking of the first split body 10 and the second split body 20.
[0065] Thus, by providing the first split body 10 and the second split body 20 which are arranged relatively along the extension direction of the center line, the first split body 10 and the second split body 20 are respectively arranged along the extension direction of the center line (such as Figure 5 By extending the first sub-body 10 and the second sub-body 20 into the bearing seat 200 in the left and right directions as shown, the mutual locking of the first sub-body 10 and the second sub-body 20 can be achieved, and on the basis of achieving the self-locking of the self-locking bearing structure 100, the installation of the self-locking bearing structure 100 can be achieved, which is easy to operate.
[0066] like Figure 8 As shown, in some embodiments, the number of the protrusion 121 can be one. Figure 8 For example, the convex portion 121 can be disposed at an end of the limiting body 122 away from the first split body 10 (eg Figure 8 Alternatively, if the limiting protrusion 12 is disposed on the second split body 20, the protrusion 121 may be disposed at an end of the limiting body 122 away from the second split body 20.
[0067] In this way, it can be ensured that the protrusion 121 is fully extended into the limiting groove 22 when the limiting protrusion 12 is plugged into the limiting groove 22, so that the protrusion 121 can fully contact the inner wall of the limiting groove 22, which is beneficial to improving the limiting effect of the limiting protrusion 12, and can reduce the probability of the limiting protrusion 12 and the limiting groove 22 being separated, thereby causing the first sub-body 10 and the second sub-body 20 to be separated, thereby helping to improve the self-locking effect of the self-locking bearing structure 100.
[0068] like Figure 6 and Fig.11 As shown, in some embodiments, the number of the first split bodies 10 can be two, the number of the second split bodies 20 can be two, and the two first split bodies 10 are arranged in an extending direction perpendicular to the center line (such as Figure 6 The two second split bodies 20 are arranged opposite to each other in the extending direction perpendicular to the center line (as shown in the upper and lower directions). Figure 6 The upper and lower directions shown) are arranged relatively.
[0069] Among them, each first sub-body 10 is locked with a second sub-body 20. On the basis of ensuring the self-locking of the self-locking bearing structure 100, the first sub-body 10 and the second sub-body 20 can be divided into multiple parts respectively, which is beneficial to reducing the size of the first sub-body 10 and the second sub-body 20, and can prevent the self-locking bearing structure 100 from interfering with the main shaft 400 during installation, thereby facilitating installation.
[0070] like Figure 5 , Figure 6 , Fig.10 and Fig.11 As shown, in some embodiments, there may be a gap 101 between the two first sub-bodies 10, and there may be a gap 101 between the two second sub-bodies 20, so that spindles 400 of various radial sizes can be matched with the self-locking bearing structure 100, that is, the gap 101 between two adjacent sub-bodies of the same type can increase as the radial size of the spindle 400 increases, which is beneficial for the self-locking bearing structure 100 to be matched with spindles 400 of larger sizes, can improve the adaptability of the self-locking bearing structure 100, and is beneficial for reducing maintenance costs.
[0071] by Figure 6 For example, in the extension direction perpendicular to the center line (such as Figure 6 In the up and down directions shown in the figure, the gap 101 is greater than or equal to the size of the limiting protrusion 12, which is conducive to the limiting protrusion 12 being separated from the limiting groove 22 in the extension direction perpendicular to the center line, and can prevent the two adjacent first sub-bodies 10 from interfering with each other when the limiting protrusion 12 is separated from the limiting groove 22, or can prevent the two adjacent second sub-bodies 20 from interfering with each other when the limiting protrusion 12 is separated from the limiting groove 22, thereby facilitating the disassembly and assembly of the self-locking bearing structure 100.
[0072] like Figure 1 , Figure 3 , Figure 8 and Fig.13 As shown, in some embodiments, the convex portion 121 can be provided on the first split body 10, in the extension direction of the center line (eg Figure 3 In the left-right direction as shown in the figure), and in the direction in which the first limiting boss 11 is away from the second limiting boss 21, the cross-sectional size of the protrusion 121 on the plane perpendicular to the extending direction of the center line gradually increases.
[0073] On the one hand, a guide surface can be formed on the side of the protrusion 121 facing the second sub-body 20, so as to guide the protrusion 121, which is beneficial to the plug-in fit of the limiting protrusion 12 and the limiting groove 22 and is easy to operate. On the other hand, a limiting surface can be formed on the side of the protrusion 121 away from the second sub-body 20, and after the limiting protrusion 12 and the limiting groove 22 are plug-in fit, the limiting surface contacts the inner wall of the limiting groove 22 to limit the protrusion 121, so as to improve the locking effect of the first sub-body 10 and the second sub-body 20 and the self-locking effect of the self-locking bearing structure 100.
[0074] Specifically, Figure 2 For example, in the direction where the first limiting boss 11 is away from the second limiting boss 21 (eg Figure 2 In the direction from right to left as shown in the figure, the cross-sectional size of the protrusion 121 on the plane perpendicular to the extension direction of the center line gradually increases, which is conducive to the first sub-body 10 extending into the bearing seat 200 and locking with the second sub-body 20; Figure 6 For example, in the direction where the first limiting boss 11 is away from the second limiting boss 21 (eg Figure 6 In the direction from left to right as shown in the figure, the cross-sectional size of the protrusion 121 on the plane perpendicular to the extending direction of the center line gradually increases.
[0075] Alternatively, the convex portion 121 may be disposed on the second split body 20 in the extension direction of the center line (eg Figure 1 In the left and right direction shown in the figure), and in the direction in which the second limiting boss 21 is away from the first limiting boss 11, the cross-sectional size of the protrusion 121 on the plane perpendicular to the extension direction of the center line gradually increases, which is conducive to the second split body 20 extending into the bearing seat 200 and locking with the first split body 10.
[0076] like Figure 3 , Figure 4 , Fig.13 and Fig.14 As shown, in some embodiments, the protrusion 121 can be a positive helical tooth, and the shape of the limiting groove 22 matches the shape of the limiting protrusion 12, so that the limiting groove 22 forms a reverse helical tooth. It can be understood that Figure 3For example, in the direction where the first limiting boss 11 is away from the second limiting boss 21 (eg Figure 3 In the direction from right to left as shown in the figure, the cross-sectional size of the positive helical teeth on the plane perpendicular to the extension direction of the center line gradually increases.
[0077] And with Figure 4 For example, in the direction where the first limiting boss 11 is away from the second limiting boss 21 (eg Figure 3 In the direction from right to left as shown, the cross-sectional size of the reverse helical teeth on the plane perpendicular to the extension direction of the center line gradually decreases, whereby, after the limiting protrusion 12 is plugged into the limiting groove 22, the positive helical teeth and the reverse helical teeth limit each other to achieve self-locking of the self-locking bearing structure 100.
[0078] Or, Fig.13 For example, in the direction where the first limiting boss 11 is away from the second limiting boss 21 (eg Fig.13 In the direction from left to right as shown in the figure, the cross-sectional dimensions of the positive helical teeth on the plane perpendicular to the extension direction of the center line gradually increase, and the cross-sectional dimensions of the positive helical teeth on the plane perpendicular to the extension direction of the center line gradually increase. Fig.14 For example, in the direction where the first limiting boss 11 is away from the second limiting boss 21 (eg Fig.14 In the direction from left to right as shown in the figure, the cross-sectional size of the reverse helical teeth on the plane perpendicular to the extension direction of the center line gradually decreases.
[0079] like Figure 8 and Fig. 9 As shown, in some embodiments, the protrusion 121 can be a triangle, and the shape of the limiting groove 22 matches the shape of the limiting protrusion 12, so that the limiting groove 22 forms a triangle. It can be understood that the number of the protrusion 121 can be one, and the triangular protrusion is arranged at the end of the limiting body 122 (such as Figure 8 left end as shown).
[0080] by Figure 8 For example, in the direction where the first limiting boss 11 is away from the second limiting boss 21 (eg Figure 8 In the direction from left to right as shown, the cross-sectional size of the triangular protrusion on the plane perpendicular to the extension direction of the center line gradually increases, and the cross-sectional size of the triangular limiting groove on the plane perpendicular to the extension direction of the center line gradually decreases. After the limiting protrusion 12 is plugged into the limiting groove 22, the triangular protrusion and the triangular limiting groove limit each other to achieve self-locking of the self-locking bearing structure 100.
[0081] In some embodiments, the first split body 10 can be a plastic part, which can enhance the elasticity of the first split body 10, that is, the protrusion 121 can undergo elastic deformation under the action of external force, which is beneficial to the plug-in fit between the limiting protrusion 12 and the limiting groove 22, and is easy to operate; the second split body 20 can be a plastic part, which can enhance the elasticity of the second split body 20, that is, the inner wall of the limiting groove 22 can undergo elastic deformation under the action of external force, which is beneficial to the plug-in fit between the limiting protrusion 12 and the limiting groove 22, and is easy to operate.
[0082] The photovoltaic tracking bracket 1000 according to the present embodiment includes a self-locking bearing structure 100. By adopting the self-locking bearing structure 100, the self-locking bearing structure 100 can be prevented from being separated from the bearing seat 200, and the number of parts can be reduced, thereby reducing costs.
[0083] like Figure 1 , Figure 5 and Fig.10 As shown, in some embodiments, the photovoltaic tracking bracket 1000 also includes: a mounting bracket 300 and a bearing seat 200, the bearing seat 200 can be installed on the mounting bracket 300, the self-locking bearing structure 100 can be self-locked in the bearing seat 200, and the main shaft 400 can be passed through the self-locking bearing structure 100, so that the rotation of the main shaft 400 can drive the self-locking bearing structure 100 to rotate relative to the bearing seat 200, which can ensure the normal operation of the photovoltaic tracking bracket 1000.
