[0027] Please refer to Figures 1 to 8 As shown, the utility model discloses a bearing assembly 100, which includes a bearing seat 1 and a bearing 2. Please refer to Figure 1 The bearing assembly 100 of the utility model is installed on the column in its normal state, with up-down direction, left-right direction and front-back direction. The bearing 2 and the bearing seat 1 have a common axial direction, that is, the axial direction of the bearing 2 and the bearing seat 1 is Figure 1 The front-to-back direction described in.

[0028] For details, please refer to Figures 1 to 4, the bearing seat 1 is a split type. The bearing seat 1 includes a first seat body part 11 and a second seat body part 12. In the up and down direction perpendicular to the axial direction, the first seat body part 11 and the second seat body part 12 are respectively covered on opposite sides of the bearing 2 and are detachably connected to each other to clamp and position the bearing 2. The first seat body part 11 and the bearing 2 and the second seat body part 12 and the bearing 2 are configured to contact through a spherical surface 200. The first seat body part 11 includes a convex first positioning portion 113, and the second seat body part 12 includes a convex second positioning portion 123. The positioning connector (to be described in detail later) passes through the first positioning portion 113 and the second positioning portion 123 to connect the first seat body part 11 and the second seat body part 12. Since the bearing assembly of the utility model directly clamps and positions the bearing 2 through the first seat body part 11 and the second seat body part 12, there is no longer a bearing shell clamped between the bearing seat and the bearing in the prior art. Therefore, the structure of the bearing assembly of the utility model is simple, and the convenience of assembly and disassembly is improved.

[0029] Please refer to Figure 3 , Figure 5 and Figure 6 The bearing assembly 100 of the utility model further includes a positioning connector, and the first seat body part 11 and the second seat body part 12 are connected to each other as a whole through the positioning connector. In a specific embodiment, the positioning connector includes a pin 31 and a pin 32. The first seat body part 11 has a first pin hole 110, and the second seat body part 12 has a second pin hole 120. The pin 31 passes through the first pin hole 110 and the second pin hole 120 in sequence for positioning. At least one end of the pin 31 is provided with a third pin hole 310, and the pin 32 is passed through the third pin hole 310. In another embodiment not shown in the figure, the pin 32 may not be present, and only the pin 31 passes through the first pin hole 110 and the second pin hole 120 and then bends to position and connect the first seat body part 11 and the second seat body part 12. In another embodiment not shown in the figure, the positioning connector may not even adopt the method of pin 31 plus pin 32, but adopt the method of hook connection. In yet another embodiment not shown in the figure, the positioning member is in the form of a combination of a bolt and a nut, and the first base body portion 11 and the second base body portion 12 are respectively provided with bolt holes allowing the bolt to pass through. One end of the bolt passes through the bolt holes on the first base body portion 11 and the second base body portion 12 and is fastened by a nut, thereby also achieving the purpose of fixing the first base body portion 11 and the second base body portion 12 in connection.

[0030] Please refer to Figure 4 and Figure 6The first seat body portion 11 has a first inner wall surface 111 and a first outer wall surface 112 which are oppositely arranged, the first inner wall surface 111 is a part of a semi-sphere, and the first positioning portion 113 is convexly arranged on the first outer wall surface 112; the second seat body portion 12 has a second inner wall surface 121 and a second outer wall surface 122 which are oppositely arranged, the second inner wall surface 121 is another part of a semi-sphere, and the second positioning portion 123 is convexly arranged on the second outer wall surface 122. The first positioning portion 113 is provided with the first pin hole 110, and the second positioning portion 123 is provided with the second pin hole 120.

[0031] Please continue to refer to Figure 4 and Figure 6 , the first inner wall surface 111 and the second inner wall surface 121 are combined into a part of a sphere, that is, on a section perpendicular to the axial direction, the section line of the first inner wall surface 111 and the section line of the second inner wall surface 121 are combined into a circle, and the section lines of both the first inner wall surface 111 and the second inner wall surface 121 are semicircles. Therefore, if the axial direction is taken as the dividing line and the first inner wall surface 111 and the second inner wall surface 121 are arranged up and down, each semicircle has left and right sides. Two second positioning parts 123 are provided on each of the left and right sides. In a specific embodiment, the pin shaft 31 extends in the front-to-back direction to penetrate the first pin hole 110 and the second pin hole 120 arranged in front and back; each of the left and right sides has two second positioning parts 123 arranged at intervals, and the first positioning part 113 is located between the two second positioning parts 123, so that the first pin hole 110 and the second pin hole 120 are arranged coaxially, thereby ensuring that the pin shaft 31 passes smoothly. That is, in the extension direction of the pin shaft 31, two second positioning portions 123 are provided, which are spaced apart from each other. The two second positioning portions 123 on each side clamp and position one first positioning portion 113, so as to improve the accuracy and convenience of positioning by locating the first positioning portion 113 between the two second positioning portions 123.

[0032] In other embodiments not shown in the figure, the pin shaft 31 can also extend in the up-down direction to penetrate the first pin hole 110 and the second pin hole 120 arranged up and down. At this time, a first positioning portion 113 and a second positioning portion 123 can be respectively arranged on each of the left and right sides, and the first positioning portion 113 and the second positioning portion 123 are arranged opposite to each other in the up-down direction. The first positioning portion 113 and the second positioning portion 123 are respectively provided with the first pin hole 110 and the second pin hole 120 arranged opposite to each other. The pin shaft 31 passes through the first pin hole 110 and the second pin hole 120 in sequence and is limited by the pin bolt 32, so that the first positioning portion 113 and the second positioning portion 123 are fixedly connected. Preferably, in order to ensure the stability of the connection, the number of the first pin hole 110 and the second pin hole 120 on each of the left and right sides can be set to multiple, and accordingly, the number of the pin shaft 31 and the pin bolt 32 is also correspondingly multiple, so that the connection between the first seat body portion 11 and the second seat body portion 12 is more stable.

[0033] Please refer to Figure 4 , the bearing 2 can be optionally split. The split bearing 2 includes a first hemispherical part 21 and a second hemispherical part 22 that are independent of each other and not connected. There is no connection relationship between the two hemispheres of the bearing 2, and there is no need for a link relationship. Because the first inner wall surface 111 and the second inner wall surface 121 of the spherical structure on the bearing seat 1 are in a shrinking state along the axial direction, the first hemispherical part 21 and the second hemispherical part 22 are respectively confined in the concave first inner wall surface 111 and the second inner wall surface 121, thereby preventing the first hemispherical part 21 and the second hemispherical part 22 from falling off during rotation. Therefore, the first hemispherical part 21 and the second hemispherical part 22 in the utility model are not linked and will not detach from each other. On the contrary, because there is no connection relationship between the two hemispheres, the bearing 2 can rotate more smoothly in the bearing seat 1.

[0034] Please continue to refer to 4. The first hemispherical part 21 has a first surface 211 facing the first seat part 11 and a second surface 212 facing the second hemispherical part 22. The second hemispherical part 22 has a third surface 221 facing the first hemispherical part 21 and a fourth surface 222 facing the second seat part 12. It is not difficult to understand that the first surface 211 and the fourth surface 222 are outer spherical surfaces 2001, and the first seat part 11 and the second seat part 12 have an inner spherical surface 2002 covered with the outer spherical surface 2001. The spherical contact between the bearing 2 and the bearing seat 1 ensures that the bearing 2 can rotate more smoothly in the bearing seat 1. It should also be pointed out that the bearing seat 1 is a cast iron part, that is, one of the metal parts. The bearing seat 1 is made of cast iron, which has high strength; the bearing 2 can be made of plastic parts to reduce costs.

[0035] The utility model also relates to a photovoltaic support, comprising a column, a main shaft and the bearing assembly 100 as described above, wherein the bearing assembly 100 is installed above the column, and the bearing seat 1 is fixedly connected to the column by bolts, and the bottom of the bolt passes through the bearing seat 1 and the column in turn and is fastened by a nut, thereby fixing the bearing seat 1 and the column. In this embodiment, the column is fixedly connected to the second seat body portion 12. The main shaft passes through the bearing assembly 100, and the second surface 212 and the third surface 221 are jointly enclosed to form a matching surface with the main shaft, and the contour shape is configured to match the main shaft, thereby ensuring the synchronous rotation of the main shaft and the bearing 2.

[0036] When assembling the bearing assembly 100 of the utility model, the second seat body part 12 is first fixedly connected to the column, and then the first positioning part 113 and the second positioning part 123 on the corresponding side of the first seat body part 11 and the second seat body part 12 are connected through the pin shaft 31 and the pin bolt 32. At this time, the other side of the first seat body part 11 and the second seat body part 12 are in a free state. Then, the first hemispherical part 21 of the bearing 2 is installed into the first seat body part 11, and the main shaft is installed on the upper side of the first seat body part 11. Then, the second hemispherical part 22 of the bearing 2 covers the main shaft and is connected to the first seat body part 11. Finally, the first positioning part 113 and the second positioning part 123 on the other side of the first seat body part 11 and the second seat body part 12 are connected through the pin shaft 31 and the pin bolt 32, thereby realizing the assembly of the bearing assembly 100 and the main shaft.

[0037] In addition, when the bearing 2 of the bearing assembly 100 is damaged and needs to be replaced, it is only necessary to remove the pin shaft 31 and the pin bolt 32 connecting one side of the first seat body part 11 and the second seat body part 12, so that one side of the first seat body part 11 and the second seat body part 12 can be rotated a certain angle relative to the pin shaft 31 on the other side and separated by a certain distance, or, remove the pin shaft 31 and the pin bolt 32 connecting both sides of the first seat body part 11 and the second seat body part 12, separate the first seat body part 11 and the second seat body part 12, remove the worn bearing 2 and install a new bearing 2, and then install the pin shaft 31 and the pin bolt 32 to fix one side of the first seat body part 11 and the second seat body part 12. Therefore, it can be seen from the above description that the detachable connection between the first seat body part 11 and the second seat body part 12 greatly facilitates the installation and maintenance of the bearing assembly 100. In addition, when the bearing 2 is replaced, it is only necessary to remove the pin 31 and the pin 32 on one side, without removing the entire bearing assembly 100 and the main shaft, which greatly saves maintenance time, simplifies the installation and maintenance procedures, and thus greatly improves work efficiency.

[0038] The photovoltaic bracket of the utility model is configured such that the bearing seat and the bearing are in spherical contact, so that the photovoltaic bracket of the utility model can achieve a larger deflection angle adjustment of the main axis, thereby adapting to the slope of the slope and having a wide range of applications.

[0039] The bearing assembly of the utility model clamps and positions the bearing 2 through the first seat body part 11 and the second seat body part 12, and no longer has the bearing shell clamped between the bearing seat and the bearing in the prior art, thereby improving the convenience of assembly and disassembly between the bearing 2 and the bearing seat 1; the first seat body part 11 and the bearing 2 and the second seat body part 12 and the bearing 2 are configured to be in spherical contact, and the photovoltaic bracket of the utility model can achieve a large deflection angle adjustment of the main shaft along with the bearing 2, so as to adapt to the slope of the slope, which not only improves the scope of application and thus improves the utilization rate of the bracket product, but also prevents the bearing 2 from accidentally falling out. In summary, the structure of the utility model is simple, which simplifies the assembly and disassembly process between the two parts of the bearing assembly 100, and can also adjust a large deflection angle to adapt to the slope of the slope, and has a wide range of applications.

[0040] The above implementation modes are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. The understanding of the present invention should be based on the technical personnel in the relevant technical field. Although the present invention has been described in detail in this specification with reference to the above implementation modes, ordinary technical personnel in the field should understand that the technical personnel in the relevant technical field can still modify or make equivalent substitutions to the present invention, and all technical solutions and improvements thereof that do not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
