[0034] The exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. If several embodiments exist, features in these embodiments may be combined with each other without conflict. When the description refers to the drawings, unless otherwise stated, the same numbers in different drawings represent the same or similar elements. The descriptions in the following exemplary embodiments do not represent all embodiments consistent with the present invention; rather, they are merely examples of apparatuses, products, and / or methods consistent with some aspects of the present invention as set forth in the claims.

[0035] The terminology used in this invention is for the purpose of describing particular embodiments only and is not intended to limit the scope of protection of this invention. The singular forms “a,” “the,” or “the” used in the specification and claims of this invention are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0036] Please refer to Figures 1 to 12 This utility model discloses a bearing housing 1, which is annular in shape. The bearing housing 1 includes a first bearing sub-seat 11 and a second bearing sub-seat 12. The first bearing sub-seat 11 includes a first end 111 and a second end 112 along the circumferential direction. The second bearing sub-seat 12 includes a third end 121 and a fourth end 122 along the circumferential direction. The second end 112 and the fourth end 122 are joined or separated along the axial direction of the bearing housing 1 using a tenon and mortise joint. 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 aligned. The first bearing sub-seat 11 and the second bearing sub-seat 12 are connected to each other to form a rotation space 101 for the bearing 2 to be installed within the rotation space 101. This arrangement can improve the assembly efficiency of the bearing housing 1 and reduce labor costs.

[0037] For ease of explanation, the following are defined: Figure 2 and attached Figure 9 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.

[0038] Please refer to Figures 4 to 8 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 the first end 111 and the second end 112 to a fixed relative position, thereby ensuring that the first bearing seat 11 and the second bearing seat 12 are limited in their width direction. The carrier is a column or column top 200 of a photovoltaic bracket. In the embodiment of this application, both the first fixing part 113 and the second fixing part 123 are 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 housing 11 and the second bearing housing 12 are engaged 1121, the first fixing part 113 and the second fixing part 123 merge 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 allows for the limiting of the first bearing housing 11 and the second bearing housing 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 engagement of the first bearing housing 11 and the second bearing housing 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.

[0039] The second end 112 and the fourth end 122 are joined by a mortise and tenon joint along the axial direction of the bearing housing 1 via a connecting structure. In this embodiment, the second connecting structure is provided at the second end 112 and the fourth end 122. By using the connecting structure, the second end 112 and the fourth end 122 can 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 and improving the assembly efficiency of the first bearing sub-seat 11 and the second bearing sub-seat 12.

[0040] The connecting structure includes a snap-fit ​​1121 and a slot 1221. The snap-fit ​​1121 is located at the second end 112, and the slot 1221 is located at the fourth end 122. The snap-fit ​​1121 and the slot 1221 engage along the axial direction of the bearing housing 1, which is consistent with the second direction D2. This arrangement allows the first bearing housing 11 and the second bearing housing 12 to be connected by snap-fit ​​1121 along the second direction D2, enabling them to be connected in the circumferential direction without the use of bolts, thus reducing the assembly difficulty of the bearing assembly 100.

[0041] Please refer to Figures 4 to 6 The first bearing seat 11 further includes a first arcuate portion 114, with a first end 111 disposed at one end of the first arcuate portion 114 and a second end 112 disposed at the other end of the first arcuate portion 114. The second bearing seat 12 includes a second arcuate portion 124, with a third end 121 disposed at one end of the second arcuate portion 124 and a fourth end 122 disposed at the other end of the second arcuate portion 124. The first arcuate portion 114 includes a first arcuate wall 1141 and a second arcuate wall 1142, which are respectively disposed opposite to each other along the thickness direction of the first arcuate portion 114, with the first arcuate wall 1141 facing the rotation space 101. Preferably, the curvature of the first arcuate wall 1141 is consistent with the outer circumferential curvature of the bearing 2. The shape of the second arcuate 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, with the third arc-shaped wall 1241 facing 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. When the buckle 1121 and the slot 1221 are engaged, the first arc-shaped wall 1141 and the third arc-shaped wall 1241 can cooperate to form a complete ring, allowing the bearing 2 to rotate more smoothly within the rotation space 101 formed by the first arc-shaped wall 1141 and the third arc-shaped wall 1241.

[0042] Please refer to Figure 5 as well as Figure 7The first fixing part 113 has a first contact surface 1111 at the connection with the first end 111, and the extension direction of the first contact surface 1111 is consistent with the extension direction of the third plane. Preferably, the first contact surface 1111 is perpendicular to the first fixing surface 1131. The second fixing part 123 has a second contact surface 1211 at the connection with the third end 121, and the extension direction of the second contact surface 1211 is consistent with the extension direction of the third plane. Preferably, the second contact surface 1211 is perpendicular to the second fixing surface 1231. This allows the first contact surface 1111 and the second contact surface 1211 to fit together along the vertical center line aa of the bearing 2 after the second end 112 and the fourth end 122 are engaged, thereby making the first arc-shaped wall 1141 and the third arc-shaped wall 1241 form a closed ring, and making the bearing 2 rotate more smoothly when connected to the surfaces of the first arc-shaped wall 1141 and the third arc-shaped wall 1241.

[0043] Furthermore, the second end 112 has a third contact surface 1123, and a buckle 1121 is disposed at the connection between the second arc-shaped wall 1142 and the third contact surface 1123. The third contact surface 1123 is on the same plane as the first contact surface 1111. The fourth end 122 has a fourth contact surface 1223, and a slot 1221 is located at the connection between the fourth contact surface 1223 and the fourth arc-shaped wall 1242. The fourth contact surface 1223 is on the same plane as the second contact surface 1211. When the buckle 1121 and the slot 1221 are engaged, the third contact surface 1123 and the fourth contact surface 1223 can fit together, thereby making the first arc-shaped wall 1141 and the third arc-shaped wall 1241 connected end to end in a closed ring shape, making the rotational connection between the bearing 2 and the first arc-shaped wall 1141 and the third arc-shaped wall 1241 smoother.

[0044] Please refer to Figure 6 as well as Figure 8 The second end 112 is provided with a first fixing block 1122, and a buckle 1121 is located on the first fixing block 1122. Specifically, the first fixing block 1122 is located at the connection between the third contact surface 1123 and the second arc-shaped wall 1142, and the first fixing block 1122 protrudes from the third contact surface 1123 in the second direction D2. The fourth end 122 is provided with a second fixing block 1222, and a slot 1221 is recessed in the second fixing block 1222 in the second direction D2. The second fixing block 1222 is located at the connection between the fourth contact surface 1223 and the fourth arc-shaped wall 1242, and the second fixing block 1222 extends out of the fourth contact surface 1223 in the second direction D2. The buckle 1121 protrudes towards the slot 1221 along the axial direction. When the first fixing block 1122 and the second fixing block 1222 are arranged opposite each other along the axis of the bearing seat 1 so that the buckle 1121 can be accurately inserted into the slot 1221, the third contact surface 1123 and the fourth contact surface 1223 are in contact, thereby fixing the second end 112 and the fourth end 122 together.
