[0027] Please refer to Figures 1 to 8 As shown, the utility model discloses a bearing assembly 100, including a bearing 2, a bearing seat 1 and a bearing cover 3. Please refer to Figure 1 The bearing assembly 100 of the utility model is installed on the column in its normal state, with up and down directions, left and right directions and front and back directions. Please refer to Figure 7 and Figure 8 , the bearing 2, the bearing seat 1 and the bearing cover 3 have a common axial direction X and radial direction Y. Figure 1 , Figure 7 and Figure 8 , the axial direction X is Figure 1 The front-to-back direction described in the figure, the radial direction Y can be the up-down direction or the left-right direction.

[0028] Please refer to Figure 2 , Figure 7 and Figure 8 , in the axial direction X, the bearing seat 1 and the bearing cover 3 are located on opposite sides of the bearing 2. The bearing 2 is limitedly clamped between the bearing seat 1 and the bearing cover 3, and the bearing seat 1 and the bearing 2, as well as the bearing cover 3 and the bearing 2, are configured to contact through a spherical surface 200. Since the bearing assembly of the utility model arranges the bearing seat 1 and the bearing cover 3 on the front and rear sides of the bearing 2, the bearing seat 1 and the bearing cover 3 clamp and position the bearing 2, and no longer has a bearing shell clamped between the bearing seat and the bearing in the prior art, so the bearing assembly of the utility model has a simple structure, which improves the convenience of assembly and disassembly.

[0029] Please refer to Figure 2 , Figure 5 and Figure 8 The bearing seat 1 has a receiving space 10, and the receiving space 10 includes a first receiving space 101 and a second receiving space 102 which are connected and arranged side by side along the axial direction X and are coaxial. The size of the first receiving space 101 in the radial direction Y is larger than the size of the second receiving space 102 in the radial direction Y. After the bearing 2 is assembled from the first receiving space 101 into the second receiving space 102, the bearing cover 3 is at least partially located in the first receiving space 101, and the bearing 2 is at least partially located in the second receiving space 102. The size of the first receiving space 101 in the radial direction Y is larger than the size of the second receiving space 102 in the radial direction Y, and its function is to enable the bearing 2 to be assembled from the rear side of the first receiving space 101 to enter the second receiving space 102 from the back to the front without accidentally escaping from the front side of the second receiving space 102. Under the condition that the bearing 2 is not accidentally dislodged from the front side of the bearing seat 1, the bearing cover 3 is at least partially located in the first receiving space 101, and the bearing 2 is at least partially located in the second receiving space 102, so that the bearing seat 1 can be on the front side of the bearing 2 and the bearing cover 3 can clamp the bearing 2 on the rear side of the bearing 2. The bearing assembly 100 of the utility model has the beneficial effects of simple structure and stability.

[0030] Of course, when the bearing seat 1 is at the front side of the bearing 2 and the bearing cover 3 is clamping the bearing 2 at the rear side of the bearing 2, a fixing device is required to connect the bearing seat 1 and the bearing cover 3 as a whole, so as to ensure the stability of the clamping. Figure 1 , Figure 2 and Figures 6 to 8The bearing assembly 100 of the utility model further includes a plurality of screws 4. Specifically, the bearing seat 1 includes an annular wall portion 11 located outside the receiving space 10 in the radial direction Y, and the annular wall portion 11 and the bearing cover 3 are each provided with a hole for the screws 4 to pass through. The plurality of screws 4 pass through the bearing cover 3 and are positioned on the annular wall portion 11 to connect the bearing seat 1 and the bearing cover 3 as a whole. The plurality of screws 4 are evenly distributed on the annular surface where the annular wall portion 11 is located to ensure balance.

[0031] Please refer to Figure 2 , Figure 4 , Figure 7 and Figure 8 The outer surface of the bearing 2 forms an outer spherical surface 2001, and the bearing seat 1 and the bearing cover 3 have an inner spherical surface 2002 facing the outer spherical surface 2001. The inner spherical surface 2002 is in a shrinking state along the axial direction, so as to limit the outer spherical surface 2001 in the concave inner spherical surface 2002 to prevent the bearing 2 from falling off during the rotation process. The bearing cover 3 includes a first plate portion 301 inserted in the first receiving space 101, a part of the inner spherical surface 2002 is located on the first plate portion 301, and another part of the inner spherical surface 2002 is located on the annular wall portion 11. That is to say, when the bearing seat 1 is at the front side of the bearing 2 and the bearing cover 3 is at the rear side of the bearing 2 to clamp the bearing 2, a part of the inner wall surface of the bearing seat 1 and another part of the inner wall surface of the bearing cover 3 together form the inner spherical surface 2002 facing the outer spherical surface 2001. When the bearing seat 1 and the bearing cover 3 are fixed, the contact position between the outer spherical surface 2001 and the inner spherical surface 2002 is adjusted so that the bearing 2 can rotate relative to the bearing seat 1 and the bearing cover 3 in the receiving space 10.

[0032] Please refer to Figure 7 and Figure 8 The bearing cover 3 further includes a second plate portion 302, and the second plate portion 302 abuts against the annular wall portion 11 in the axial direction X. The screw 4 passes through the second plate portion 302 and is positioned on the annular wall portion 11. Figure 3 The second plate portion 302 of the bearing cover 3 is provided with a plurality of first holes 30 for the screws 4 to pass through. Figure 5, the annular wall portion 11 of the bearing seat 1 is also provided with a plurality of second holes 110 for the screws 4 to pass through. The first holes 30 need to be matched and aligned with the second holes 110 one by one before the screws 4 can be passed through the second plate portion 302 and positioned on the annular wall portion 11. The bearing 2 is first assembled into the bearing seat 1 from the rear side of the bearing seat 1, and then the bearing cover 3 is assembled to the bearing seat 1 on the rear side of the bearing seat 1 to cover the bearing 2, and then the bearing cover 3 is fixedly connected to the bearing seat 1 by the screws 4. In other words, the bearing cover 3 and the bearing 2 are assembled into the bearing seat 1 from the back to the front, and the bearing 2, the bearing cover 3 and the screws 4 are assembled to the bearing seat 1 in sequence, which is simple to operate.

[0033] Please refer to Figure 8 The annular wall portion 11 includes a front end face 111 and a rear end face 112 which are oppositely arranged in the axial direction X. The front end face 111 faces away from the bearing cover 3, and the bearing 2 partially exposes the front end face 111. The bearing 2 partially exposes the front end face 111, thereby avoiding interference between the main shaft passing through the bearing 2 and the bearing seat 1 when rotating.

[0034] Please refer to Figure 7 and Figure 8 The annular wall portion 11 includes an inner end face 113 and an outer end face 114 which are oppositely arranged in the radial direction Y, and the outer end face 114 is flush with the second plate portion 302. The flush arrangement ensures that the outer lines of the bearing assembly 100 of the utility model are smooth and not abrupt, thereby improving the aesthetics of the bearing assembly 100 of the utility model.

[0035] Please refer to Figures 3 to 5 The bearing seat 1 is an integrated type and the bearing 2 and the bearing cover 3 are both split up and down. The integrated bearing seat 1 is beneficial to the strength and stability of the overall structure, and the split bearing 2 and the bearing cover 3 are beneficial to assembly and simple operation.

[0036] Please refer to Figure 4 The bearing 2 includes a first hemispherical part 21 and a second hemispherical part 22. The first hemispherical part 21 and the second hemispherical part 22 are independent of each other and not connected, so that the two independent hemispheres can be assembled into the bearing seat 1. Please refer to Figure 3The bearing cover 3 includes a first cover part 31 and a second cover part 32. The first cover part 31 is provided with a first convex block 311 on the left side and a first groove 312 on the right side. The second cover part 32 is provided with a second groove 321 on the left side and a second convex block 322 on the right side. The first convex block 311 is inserted into the second groove 321 and the second convex block 322 is inserted into the first groove 312. The concave and convex fit on the left and right sides realizes the positioning between the first cover part 31 and the second cover part 32. With such a configuration, the upper and lower parts of the bearing cover 3 are of a central symmetrical structure, that is, the first cover part 31 completely overlaps with the second cover part 32 after rotating 180 degrees about the axis. In other words, the first cover part 31 and the second cover part 32 have the same structure. The first cover part 31 and the second cover part 32 can be produced on the same mold production line, which reduces the production cost.

[0037] It should also be pointed out that the bearing seat 1 and the bearing cover 3 are both plastic parts; the bearing 2 can be either a plastic part or a metal part. The bearing seat 1 and the bearing cover 3 are made of plastic parts, which have a light structure and low manufacturing cost; in the preferred embodiment, the bearing 2 is also a plastic part, that is, the bearing seat 1, the bearing 2 and the bearing cover 3 in the specific embodiment of the utility model are all plastic parts, which is to reduce costs on the one hand, and reduce the wear rate between the bearing 2 and the bearing seat 1 and the bearing cover 3 on the other hand, thereby extending the service life of the bearing assembly 100 of the utility model.

[0038] The utility model also relates to a photovoltaic support, including 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 main shaft passes through the bearing assembly 100. Specifically, a bolt is provided at the bottom of the bearing seat 1, and one end of the bolt passes through the bearing seat 1 and the column respectively and is fastened by a nut, thereby fixing the bearing seat 1 to the column, and the inner ring surface contour shape of the bearing 2 matches the main shaft to ensure the synchronous rotation of the bearing 2 and the main shaft. The utility model photovoltaic support can achieve a larger deflection angle adjustment of the main shaft by configuring the bearing seat and the bearing, and the bearing cover and the bearing to be in spherical contact, so as to adapt to the slope of the slope and has a wide range of applications.

[0039] The bearing assembly 100 of the utility model arranges the bearing seat 1 and the bearing cover 3 on opposite sides of the bearing 2 in the axial direction. Since the bearing 2 is clamped between the bearing seat 1 and the bearing cover 3 in the front-rear direction, there is no longer a bearing shell clamped between the bearing seat and the bearing in the prior art, thereby improving the convenience of assembling the bearing 2, the bearing seat 1 and the bearing cover 3; by configuring the bearing seat 1 and the bearing 2 and the bearing cover 3 and the bearing 2 to be in spherical contact, the photovoltaic bracket of the utility model can adjust the main shaft with the bearing 2 to a larger deflection angle, 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, and can also adjust the deflection angle to a larger extent to adapt to the slope of the slope, and has a wide range of applications.
