[0034] The terms used in the present invention are only for the purpose of describing specific embodiments, and are not intended to limit the scope of protection of the present invention. The singular forms "a", "said" or "the" used in the specification and claims of the present invention are also intended to include plural forms, unless the context clearly indicates other meanings.

[0035] Please refer to Figures 1 to 11 The present invention discloses a bearing assembly 100, which includes a bearing 1 and a bearing seat 2. The bearing seat 2 is annular and includes a first bearing sub-seat 21 and a second bearing sub-seat 22 along the circumferential direction. The first bearing sub-seat 21 includes a first end 201 and a second end 202 in the circumferential direction, and the second bearing sub-seat 22 includes a third end 203 and a fourth end 204 in the circumferential direction. The first end 201 is connected to the third end 203 to form a first connection position. The second end 202 is connected to the fourth end 204 to form a second connection position. An angle α is formed between the connecting line aa of the first connection position and the second connection position and the vertical center line bb of the bearing seat 2. The first bearing sub-seat 21 and the second bearing sub-seat 22 are connected by a connecting structure mortise and tenon to form an annular bearing seat 2, and the bearing 1 is rotatably arranged in the rotating space 1001 on the radial inner side of the annular bearing seat 2. The bearing 1 has a containing space for the connecting shaft 300 of the photovoltaic bracket 10 to pass through.

[0036] For the convenience of explanation, the following definitions are given: Figure 4-5 As shown, the height direction of the bearing seat 2 is the first direction D1, the width direction of the bearing seat 2 is the second direction D2, and the thickness direction of the bearing seat 2 is the third direction D3. The first direction D1, the second direction D2, and the third direction D3 are perpendicular to each other. That is, the vertical center line bb of the bearing seat 2 extends along the first direction D1. Figure 1As shown, the cross section of the bearing seat 2 is a circle. The vertical center line bb of the bearing seat 2 is the center line through the center of the bearing seat 2 from the angle perpendicular to the end face of the bearing seat 2 after the bearing seat 2 is installed and fixed. The first connection position and the second connection position are respectively located on the circumference of the circle formed after the first bearing sub-seat 21 and the second bearing sub-seat 22 are snap-connected. Therefore, the connecting line aa of the first connection position and the second connection position also passes through the center of the bearing seat 2. In the cross section of the bearing seat 2, the first angle between the center line through the first connection position and the vertical center line bb is α1. In the cross section of the bearing seat 2, the second angle between the center line through the second connection position and the vertical center line bb is α2, and the values ​​of the first angle α1 and the second angle α2 are equal. Preferably, the angle α is 0-45 degrees. In other words, the angle range of α1 and α2 is 0-45 degrees. In this way, the first connection position and the second connection position are relatively staggered, and then the first bearing sub-seat 21 and the second bearing sub-seat 22 can decompose the borne gravity into horizontal and vertical components through an inclined connection. The horizontal component can enhance the bonding force between the first bearing sub-seat 21 and the second bearing sub-seat 22 to realize load-bearing and position limiting for the bearing 1, thereby improving the rotation stability of the bearing 1.

In the first embodiment, the first end 201 and the third end 203 are connected by the first connection structure, and the second end 202 and the fourth end 204 are connected by the second connection structure, so that the first bearing sub-seat 21 and the second bearing sub-seat 22 can be buckled to form a complete ring. In this way, the first bearing sub-seat 21 and the second bearing sub-seat 22 can also decompose the weight carried into a horizontal component and a vertical component through an inclined connection mode. The horizontal component can enhance the combination force of the first bearing sub-seat 21 and the second bearing sub-seat 22 to achieve load-bearing and limit the bearing 1, thereby improving the rotation stability of the bearing 1.

In this way, the first bearing sub-seat 21 and the second bearing sub-seat 22 are engaged with each other, so that the first bearing sub-seat 21 and the second bearing sub-seat 22 can be engaged with each other in the circumferential direction without using bolts, thereby reducing the assembly difficulty of the bearing assembly 100. In other embodiments, the first end 201 and the second end 202 of the first bearing sub-seat 21 are respectively provided with a first clip 221 and a second clip 212, the third end 203 and the fourth end 204 of the second bearing sub-seat 22 are respectively provided with a first slot 211 and a second slot 222, the first clip 221 is matched and connected with the first slot 211 to form a first connection structure, and the second clip 212 is matched and connected with the second slot 222 to form a second connection structure.

In the embodiment of the present application, the first fixing portion 213 and the second fixing portion 223 are both flat blocks, the first fixing portion 213 has a first fixing surface 2001, and the second fixing portion 223 has a second fixing surface 2002. When the first bearing sub-seat 21 and the second bearing sub-seat 22 are snap-connected to each other, the first fixing portion 213 and the second fixing portion 223 are combined into a whole at the first connection position, and at this time, the first fixing surface 2001 and the second fixing surface 2002 are coplanar. Here, the plane where the first fixed surface 2001 and the second fixed surface 2002 are located is defined as the first plane of the bearing seat 2, and the end surface formed by the first bearing sub-seat 21 and the second bearing sub-seat 22 is the second plane.

Preferably, the angle α is 0-45 degrees, so that the first bearing sub-seat 21 and the second bearing sub-seat 22 can be connected in an inclined snap-fit ​​manner. When connected in this way, the force exerted on the first bearing sub-seat 21 located below and the separation force F exerted on the first connection position and the second connection position will be decomposed into a first component force F1 and a second component force F2. The first component force F1 can enhance the bonding force between the first bearing sub-seat 21 and the second bearing sub-seat 22, thereby reducing the separation force F exerted on the bearing seat 2 at the first connection position and the second connection position, thereby increasing the load-bearing capacity of the entire bearing seat 2 and strengthening the support and limiting effect on the bearing 1.

When the first buckle 221 is engaged with the first clamping groove 211 and the second buckle 212 is engaged with the second clamping groove 222, the first arc-shaped portion 214 and the second arc-shaped portion 224 can cooperate to form a complete ring, so that the bearing 1 can rotate in the rotation space 1001 formed by the first arc-shaped portion 214 and the second arc-shaped portion 224.

[0042] The first arcuate portion 214 includes a first arcuate wall 2141 and a second arcuate wall 2142, the first arcuate wall 2141 and the second arcuate wall 2142 are respectively arranged opposite to each other along the thickness direction of the first arcuate portion 214, and the first arcuate wall 2141 faces the rotation space 1001.
