The first end 111 and the third end 121 are fixed to a carrier so that the first end 111 and the third end 121 are mated. The first bearing sub-seat 11 and the second bearing sub-seat 12 are connected to each other to form an annulus and have a rotation space 101 for accommodating the bearing and allowing the bearing to rotate around the axis of the bearing housing 1 within the rotation space 101. This arrangement can improve the assembly efficiency of the bearing housing 1 and reduce labor costs.

[0039] For ease of explanation, the following definitions are provided. Figure 1 The height direction of the bearing housing 1 shown is the first direction D1, the width direction of the bearing housing 1 is the second direction D2, and the thickness direction of the bearing housing 1 is the third direction D3. The first direction D1, the second direction D2, and the third direction D3 are all perpendicular to each other.

[0040] Please refer to Figures 1 to 3 The first bearing seat 11 is provided with a first fixing part 113, which extends outward in a straight line from the first end 111. The second bearing seat 12 is provided with a second fixing part 123, which extends outward in a straight line from the third end 121. The first fixing part 113 and the second fixing part 123 extend opposite to each other from the connection point. The first fixing part 113 and the second fixing part 123 are used to fix to a carrier so that their relative positions are fixed, thereby ensuring that the first bearing seat 11 and the second bearing seat 12 are limited. The carrier is the column or column top 200 of the photovoltaic bracket. In the embodiment of this application, the first fixing part 113 and the second fixing part 123 are both flat blocks. The first fixing part 113 has a first fixing surface 1131, and the second fixing part 123 has a second fixing surface 1231. When the first bearing seat 11 and the second bearing seat 12 are along the radial direction of the bearing seat 1, i.e., as shown in the attached figure... Figure 1After the bearing housing 1 shown is snapped together in the first direction D1, the first fixing part 113 and the second fixing part 123 are tenon-jointed into a whole. At this time, the first fixing surface 1131 and the second fixing surface 1231 are coplanar. The first fixing part 113 and the carrier are connected by fasteners 300, and the second fixing part 123 and the carrier are connected by fasteners 300. This can limit the first bearing sub-seat 11 and the second bearing sub-seat 12 in the thickness and height directions of the bearing housing 1. Here, the plane containing the first fixing surface 1131 and the second fixing surface 1231 is defined as the first plane of the bearing housing 1, and the end face formed by the snapping of the first bearing sub-seat 11 and the second bearing sub-seat 12 is defined as the second plane. The first plane is perpendicular to the second plane. The bearing housing 1 also has a third plane, which is perpendicular to both the first plane and the second plane.

[0041] Please refer to Figures 1 to 4 The first end 111 and the third end 121 are mortised and tenoned together along the axial direction of the bearing housing 1 via a first connecting structure. In this embodiment, the first connecting structure is provided at the first end 111 and the third end 121, enabling the first end 111 and the third end 121 to be connected along the axial direction of the bearing housing 1, thereby limiting the first bearing sub-seat 11 and the second bearing sub-seat 12 in the axial direction of the bearing housing 1. Similarly, the second end 112 and the fourth end 122 are mortised and tenoned together along the axial direction of the bearing housing 1 via a second connecting structure. In this embodiment, the second connecting structure is provided at the second end 112 and the fourth end 122, enabling the second end 112 and the fourth end 122 to be connected along the axial direction of the bearing housing 1, thereby limiting the first bearing sub-seat 11 and the second bearing sub-seat 12 in the axial direction of the bearing housing 1. In this embodiment, the first connecting structure and the second connecting structure are arranged vertically opposite each other along the first direction D1 of the bearing housing 1 to improve the assembly efficiency of the first bearing sub-seat 11 and the second bearing sub-seat 12.

[0042] Specifically, the first connecting structure includes a first snap-fit ​​1121 and a first slot 1111, with the first snap-fit ​​1121 engaging with the first slot 1111. The second connecting structure includes a second snap-fit ​​1211 and a second slot 1221, with the second snap-fit ​​1211 and the second slot 1221 engaging with each other. The first end 111 and the second end 112 of the first bearing housing 11 are respectively provided with the first slot 1111 and the first snap-fit ​​1121, and the third end 121 and the fourth end 122 of the second bearing housing 12 are respectively provided with the second snap-fit ​​1211 and the second slot 1221. This arrangement enables the first bearing housing 11 and the second bearing housing 12 to be connected vertically along the first direction D1, allowing them to be connected in the circumferential direction without bolts, thus reducing the assembly difficulty of the bearing assembly 100. In other embodiments, the first end 111 and the second end 112 of the first bearing sub-seat 11 are respectively provided with a first buckle 1121 and a second buckle 1211, and the third end 121 and the fourth end 122 of the second bearing sub-seat 12 are respectively provided with a first groove 1111 and a second groove 1221. The first buckle 1121 and the first groove 1111 are engaged and connected to form a first connection structure, and the second buckle 1211 and the second groove 1221 are engaged and connected to form a second connection structure.

[0043] Please refer to Figures 5 to 6 A first slot 1111 is located at the first end 111, a first buckle 1121 is located at the third end 121, a second buckle 1211 is located at the second end 112, and a second slot 1221 is located at the fourth end 122. The first buckle 1121 engages with the first slot 1111 from above and downwards along the vertical center line aa. The second buckle 1211 engages with the second slot 1221 from below and downwards along the vertical center line aa. This allows the first bearing seat 11 and the second bearing seat 12 to achieve left-right interlocking connection while also providing reinforced support and limiting the bearing position.

[0044] Specifically, the first bearing seat 11 further includes a first arcuate portion 114, with a first end 111 disposed at the upper end of the first arcuate portion 114 in the first direction D1, and a second end 112 disposed at the lower end of the first arcuate portion 114 in the first direction D1. The second bearing seat 12 includes a second arcuate portion 124, with a third end 121 disposed at the upper end of the second arcuate portion 124 in the first direction D1, and a fourth end 122 disposed at the lower end of the second arcuate portion 124 in the first direction D1. In the embodiment of this application, a first slot 1111 is disposed at the connection between the first fixing portion 113 and the first end 111, and a second buckle 1211 is disposed at the second end 112, extending from the second end 112 along the second direction D2 towards one side of the rotation space 101. The first latch 1121 is disposed at the connection between the second fixing part 123 and the third end 121, and the first latch 1121 extends from the third end 121 along the second direction D2 toward one side of the rotation space 101. The second slot 1221 is disposed at the fourth end 122. When the first latch 1121 engages with the first slot 1111 and the second latch 1211 engages with the second slot 1221, the first arc-shaped part 114 and the second arc-shaped part 124 can cooperate to form a complete ring, so that the bearing can rotate within the rotation space 101 formed by the first arc-shaped part 114 and the second arc-shaped part 124.

[0045] The first arc-shaped portion 114 includes a first arc-shaped wall 1141 and a second arc-shaped wall 1142. The first arc-shaped wall 1141 and the second arc-shaped wall 1142 are respectively arranged opposite to each other along the thickness direction of the first arc-shaped portion 114, and the first arc-shaped wall 1141 faces the rotation space 101. Preferably, the curvature of the first arc-shaped wall 1141 is consistent with the outer circumferential curvature of the bearing 2. The shape of the second arc-shaped wall 1142 is not limited. The second arc-shaped portion 124 includes a third arc-shaped wall 1241 and a fourth arc-shaped wall 1242. The third arc-shaped wall 1241 and the fourth arc-shaped wall 1242 are respectively arranged opposite to each other along the thickness direction of the second arc-shaped portion 124, and the third arc-shaped wall 1241 faces the rotation space 101. Preferably, the curvature of the third arc-shaped wall 1241 is consistent with the outer circumferential curvature of the bearing 2. The shape of the fourth arc-shaped wall 1242 is not limited. Therefore, when the first bearing seat 11 and the second bearing seat 12 are snapped together, the first arc-shaped wall 1141 and the third arc-shaped wall 1241 can be connected end to end to form a circular structure. The circular structure is concentric with the bearing 2, so that the bearing 2 can rotate within the rotation space 101.

[0046] The connection between the first fixing part 113 and the first end 111 has a first contact surface 1112. A first slot 1111 is located to the left of the first contact surface 1112, and the extending direction of the first contact surface 1112 is consistent with the extending direction of the third plane. Preferably, the first contact surface 1112 is perpendicular to the first fixing surface 1131. The connection between the second fixing part 123 and the third end 121 has a second contact surface 1212. A first buckle 1121 is disposed on the second contact surface 1212, and the extending direction of the second contact surface 1212 is consistent with the extending direction of the third plane. Preferably, the second contact surface 1212 is perpendicular to the second fixing surface 1231. This allows the first buckle 1121 to engage with the first slot 1111, and the first contact surface 1112 and the second contact surface 1212 to fit together along the vertical center line aa. This makes the first arc-shaped wall 1141 and the third arc-shaped wall 1241 connect end to end in a closed ring, making the bearing 2 more smoothly connected when rotating between the first arc-shaped wall 1141 and the second arc-shaped wall 1142.

[0047] Furthermore, the second end 112 has a third contact surface 1122, and the second buckle 1211 is disposed on the third contact surface 1122. The third contact surface 1122 is on the same plane as the first contact surface 1112. The fourth end 122 has a fourth contact surface 1222, and the second slot 1221 is located on the right side of the fourth contact surface 1222. The fourth contact surface 1222 is on the same plane as the second contact surface 1212. When the second buckle 1211 and the second slot 1221 are engaged, the third contact surface 1122 and the fourth contact surface 1222 can fit together, so that the first arc-shaped wall 1141 and the third arc-shaped wall 1241 are connected end to end to form a closed ring, and the bearing 2 rotates more smoothly when connected to the first arc-shaped wall 1141 and the second arc-shaped wall 1142.

[0048] Please refer to Figures 5 to 7 The first slot 1111 includes a bottom wall 11111 and a side wall 11112 perpendicularly disposed to the bottom wall 11111. The side wall 11112 has a stepped portion 1113, and the first buckle 1121 engages with the stepped portion 1113. Specifically, the first slot 1111 is recessed downward from the first fixing surface 1131 along the first direction D1. The bottom wall 11111 is perpendicular to the first contact surface 1112, and the side wall 11112 faces the first contact surface 1112. The stepped portion 1113 includes two portions, which are spaced apart and opposite to each other along the third direction D3. The first buckle 1121 engages with the two stepped portions 1113 to connect the first end 111 of the first bearing seat 11 and the third end 121 of the second bearing seat 12.

[0049] Please refer to Figures 5 to 7The stepped portion 1113 includes a first mating surface 11131 and a second mating surface 11132, both of which are perpendicular to the bottom wall 11111 of the groove.

The second mating surfaces 11132 of the two stepped portions 1113 are arranged face-to-face along a third direction D3. The first mating surface 11131 faces the groove sidewall 11112 and is connected to the groove sidewall 11112, and the first mating surface 11131 and the first contact surface 1112 are arranged opposite to each other. The groove bottom wall 11111, the groove sidewall 11112, and the two first mating surfaces 11131 form a snap-fit ​​space 1002, and the two second mating surfaces 11132 and the groove bottom wall 11111 form a mating space 1001. One end of the body portion 12111 is perpendicular to the second contact surface 1212, and the snap-fit ​​portion 12112 is provided at the other end of the body portion 12111. The main body 12111 includes a top wall 121111, a bottom wall 121112 disposed opposite to the top wall 121111 in a first direction D1, and two side walls 121113 connecting the top wall 121111 and the bottom wall 121112 in a third direction D3. The two guide surfaces 121121 of the latching part 12112 are respectively perpendicularly disposed to the corresponding side walls 121113. The latching part 12112 also includes an arc-shaped surface 121122, which is arc-shaped. The two ends of the arc-shaped surface 121122 are respectively connected to the two guide surfaces 121121. The arc-shaped surface 121122 protrudes outward along a straight line in the second direction D2. When the first latch 1121 engages with the first slot 1111 from top to bottom, the latch portion 12112 is located within the latching space 1002, the arc-shaped surface 121122 is in contact with the side wall 11112 of the slot, and the guide surface 121121 is in contact with the first mating surface 11131. Additionally, the body portion 12111 is located within the mating space 1001, with its two side walls 121113 respectively in contact with the corresponding second mating surfaces 11132, and its bottom wall 121112 in contact with the bottom wall 11111 of the slot. This ensures that the first latch 1121 and the first slot 1111 are securely latched and not easily loosened.

[0050] In the embodiments of this application, the first buckle 1121 and the second buckle 1211 have the same structure, and the first slot 1111 and the second slot 1221 have the same structure.

[0051] In the second embodiment, the first connecting structure is located at the first end 111 or the third end 121, and the second connecting structure is located at the second end 112 or the fourth end 122. Specifically, the bearing assembly 100 also includes a first connecting seat and a second connecting seat.
