Description

Technical field

[0001] The present invention relates to a field, and in particular to an integrated stamped bearing seat system for a photovoltaic multi-point mechanical linkage bracket. [Background Technology]

[0002] As the scale of global photovoltaic installations continues to expand, market demand for tracking brackets is also increasing year by year. The bearing seat system is one of the key node components that ensures the precise rotation and real-time tracking of photovoltaic tracking brackets. Its performance directly affects the bracket's stability, tracking accuracy, and power generation efficiency. In existing technologies, the principle of multi-point mechanical transmission tracking brackets is to rely on the drive shaft to drive the main shaft to rotate. To ensure smooth rotation and prevent wear, both the drive shaft and the main shaft need to be equipped with corresponding bearings. Traditional bearing seat systems have the following main defects:

[0003] 1. Mechanical transmission bearing housings are often designed using a multi-part assembly approach, where multiple welded or extruded parts (such as the column top seat, bearing lower seat, bearing upper seat, and transmission shaft bearing seat) are assembled together to form a complete bearing housing system. While this type of bearing housing meets basic requirements, the multi-part coordinated bearing housing system is not only complex in structure and difficult to assemble and debug, but also has low production and cost-effectiveness, weakening the market competitiveness of tracking brackets.

[0004] 2. The spindle bearing seat and the drive shaft bearing seat of the traditional design are not a whole, and the center distance between the drive shaft and the spindle is often fixed in the design, which means that the center distance between the spindle bearing and the drive shaft bearing is also a fixed value. The relative position of the two needs to be manually adjusted through the bar holes during installation. Manual adjustment cannot guarantee the center distance position accuracy of the main shaft bearing and the drive shaft bearing mounting holes, and manual adjustment efficiency is low.

[0005] In view of this, the inventors of this case conducted in-depth research on the above-mentioned issues, which led to the creation of this case. [Summary of the invention]

[0040] In order to better understand the technical solution of the present invention, the technical solution of the present invention will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0041] See also Figures 1 to 14As shown, the present invention provides an integrated stamped bearing seat system 100 for a photovoltaic multi-point mechanical linkage bracket, including a bearing cover plate 1 and a bearing seat 2, and the bearing cover plate 1 and the bearing seat 2 are detachably connected by fasteners 3; the bearing cover plate 1 includes a spherical covering surface 11 whose inner surface is adapted to the main shaft bearing 4, and the top surface of the bearing seat 2 forms a supporting spherical surface 21 for supporting the main shaft bearing 4; after the bearing cover plate 1 and the bearing seat 2 are connected, the spherical covering surface 11 and the supporting spherical surface 21 are surrounded to form a first through hole 5 for assembling the main shaft bearing 4 and the main shaft 200, which meets the free rotation of the main shaft 200 in any direction and adapts to the installation requirements of photovoltaic tracking brackets on different slopes; a second through hole 22 for assembling the drive shaft bearing 301 is formed in the middle of the bearing seat 2, so that the drive shaft bearing 301 can rotate freely in any direction and adapt to the installation requirements of photovoltaic tracking brackets on different slopes. The design of the second through hole 22 makes it possible to install the drive shaft bearing 301 and the drive shaft 300 without the need for an independent drive shaft bearing seat.

[0042] The integrated stamped bearing seat system 100 of the present invention has the following beneficial technical effects:

[0043] 1. The main shaft bearing 4 and the transmission shaft bearing can be installed simultaneously in one bearing seat system 100, which reduces the number of redundant parts in the traditional design, simplifies the installation steps, and improves the installation efficiency. The design of this stamped bearing seat system 100 can perfectly avoid the defect that the relative positions of the two bearings (the main shaft bearing 4 and the transmission shaft bearing 301) need to be manually adjusted. During the stamping process, the center distance position accuracy of the main shaft bearing 4 mounting hole and the transmission shaft bearing 301 mounting hole can be guaranteed, and the relative installation dimensions of the two can be better guaranteed.

[0044] 2. The bearing seat system 100 only includes two metal parts, the bearing cover plate 1 and the bearing seat 2, which can avoid the problem of slipping between the main shaft 200 and the main shaft bearing 4. The main shaft bearing 4 and the transmission shaft bearing 301 can be easily installed through four sets of flange bolt fastening components, which greatly reduces the type and number of parts, optimizes the installation steps and efficiency of the photovoltaic system, and is of great help in improving the market competitiveness of the multi-point mechanical linkage tracking bracket.

[0045] 3. By designing the bearing seat 2 to include a first bearing support 23 and a second bearing support 24 that are connected to each other in a back-to-back manner, the back-to-back installation method of the two bearing supports improves the overall compressive strength and torsional resistance of the bearing seat system 100 compared to the use scenario of a single bearing seat independent support; the double bearing supports adopt local drawing at the back-to-back interlocking point to avoid local deformation of the bearing supports after interlocking due to the existence of back-to-back gaps, thereby avoiding weakening of the overall rigidity.

[0046] 4. The bearing seat system 100 adopts a stamping process, which is different from the traditional welding or extrusion process. The stamping process is not only simple in process and meets the requirement of one-piece molding of the bearing seat 2, but also greatly improves production efficiency and reduces production costs.

[0047] In the present invention, the two ends of the spherical covering surface 11 are smoothly transitioned and tightened inward to form a left hanging ear portion 12 and a right hanging ear portion 13. The left hanging ear portion 12 includes a first left flat plate 121 and a second left flat plate 122, and a left assembly gap 123 is formed between the first left flat plate 121 and the second left flat plate 122. The right hanging ear portion 13 includes a first right flat plate 131 and a second right flat plate 132, and a right assembly gap 133 is formed between the first right flat plate 131 and the second right flat plate 132. The two ends of the spherical covering surface 11 are rounded to remove the sharp corners at both ends, so as to prevent the main shaft bearing 4 from being scratched by the sharp corners of the spherical covering surface 11 while rotating on the spherical covering surface 11, thereby preventing the appearance of the main shaft bearing 4 from being damaged.

[0048] The bearing seat 2 includes a first bearing support 23 and a second bearing support 24 that are connected to each other in a back-to-back manner. Compared to the use scenario where a single bearing seat is independently supported, the back-to-back installation of the first bearing support 23 and the second bearing support 24 improves the overall compressive strength and torsional resistance of the bearing seat system 100. The first bearing support 23 includes a back plate 231. The top of the back plate 231 is provided with a left insert plate 232 that is inserted into the left assembly gap 123 and a right insert plate 233 that is inserted into the right assembly gap 133. The back plate 231, the left insert plate 232, and the right insert plate 233 are arranged in a Y shape. A half-spherical support surface 21 is stamped between the left insert plate 232 and the right insert plate 233. The end surface of this half-spherical support surface 21 is rounded to remove sharp corners. This prevents the spindle bearing 4 from being scratched by the sharp corners of the support surface 21 while rotating on it, thereby preventing the appearance of the spindle bearing 4 from being damaged. Open flanges are formed on the left and right sides of the support surface 21 to prevent the spindle bearing 4 from being pinned by spherical molding errors of the support surface 21 when rotating within the bearing seat 2. The structure of the second bearing support 24 is the same as that of the first bearing support 23.

[0049] In the present invention, the first left plate 121 is provided with a first left punching hole 1211, the second left plate 122 is provided with a second left punching hole, the left inserting plate 232 is provided with a first left drawn circular groove 2321, and the first left drawn circular groove 2321 is provided with a third left punching hole 2322; the first right plate 131 is provided with a first right punching hole, the second right plate 132 is provided with a second right punching hole 1321, the right inserting plate 233 is provided with a first right drawn circular groove 2331, and the first right drawn circular groove 2331 is provided with a third right punching hole 2332. The back surfaces of the first left-drawn circular groove 2321 of the first bearing support 23 and the first right-drawn circular groove 2331 of the second bearing support 24 abut against each other. This eliminates the gap between the upper portions of the first and second bearing supports 23, 24 when they are installed facing away from each other and locked on the column 400. This prevents deformation and displacement of the supporting spherical surface 21 due to the gap after back-to-back installation and locking, further ensuring that the rotational fit of the spindle bearing 4 on the bearing seat 2 is not affected. The first left punched hole 1211, the second left punched hole, and the third left punched hole 2322 are used to install the first flange bolt fastening assembly 31; the first right punched hole 1321, the second right punched hole 2332, and the third right punched hole 2332 are used to install the second flange bolt fastening assembly 32, thereby achieving a detachable connection between the bearing cover plate 1 and the bearing seat 2.

[0050] In the present invention, a second left drawn circular groove 2323 is formed between the second through-hole 22 and the third left punched hole 2322, and a fourth left punched hole 2324 is formed in the second left drawn circular groove 2323. A second right drawn circular groove 2333 is formed between the second through-hole 22 and the third right punched hole 2332, and a fourth right punched hole 2334 is formed in the second right drawn circular groove 2333. The design of the drawn circular groove and punched holes can be used to install the third flange bolt fastening assembly 33 and the fourth flange bolt fastening assembly 34, which can not only form the two bearing supports into a whole, but also make the fourth left punched hole 2324 and the fourth right punched hole 2334 fit more tightly after the bearing supports are assembled, thereby reducing the inner spherical surface error formed by the assembly, and further reducing the amount of movement of the transmission shaft bearing 301 in the second through-hole 22.

[0051] In the present invention, the left and right sides of the first bearing support 23 are formed with left and right flanges 234 and 235, respectively. The design of the left and right flanges 234 and 235 strengthens the structural rigidity while improving the support's wind resistance. It also allows for maintenance after the bearing cover 1 is removed, facilitating maintenance while also improving overall structural strength. The left and right flanges 234 and 235 leave a certain amount of space between them and the top of the backplate 231, facilitating subsequent maintenance of the main shaft 200 or the main shaft bearing 4 by removing the bearing cover 1.

[0052] In the present invention, a letter symbol reinforcement rib 236 is provided below the second through hole 22 , which not only strengthens the strength of the lower portion of the back plate 231 that would otherwise be weakened after punching, but also takes into account the uniqueness and aesthetics of the appearance of the back plate 231 .

[0053] In the present invention, two vertical strip holes 237 are provided below the letter symbol reinforcement rib 236. The vertical strip holes 237 are located at the lower portion of the back plate 231 and are used to lock fasteners, thereby fixing the bearing seat 2 on the column 400. The vertical strip holes 237 can meet the requirements of vertical height adjustment of the back plate 231 on the column 400. The column 400 is provided with a transverse strip hole 401 to meet the requirements of horizontal free adjustment of the back plate 231 on the column 400. The design of the double vertical strip holes 237, combined with the double transverse strip holes 401 on the column 400, eliminates the need for other adjustment parts and easily meets the requirements of horizontal and vertical free adjustment, thereby solving the problems of redundant parts and cumbersome installation and debugging steps in the bearing seat system 100, and improving the convenience of installation and debugging.

[0054] In the present invention, the fastener 3 includes a first flange bolt fastening assembly 31 for locking the left hanging ear 12 and the left insert plate 232, a second flange bolt fastening assembly 32 for locking the right hanging ear 13 and the right insert plate 233, a third flange bolt fastening assembly 33 passing through the fourth left punching hole 2324 of the first bearing support 23 and the fourth right punching hole 2334 of the second bearing support 24 for locking the first bearing support 23 and the second bearing support 24, and a fourth flange bolt fastening assembly 34 passing through the fourth right punching hole 2334 of the first bearing support 23 and the fourth left punching hole 2324 of the second bearing support 24 for locking the first bearing support 23 and the second bearing support 24. When the spindle bearing 4 or the spindle 200 needs to be maintained or replaced, only one of the first flange bolt fastening assembly 31 or the second flange bolt fastening assembly 32 needs to be disassembled, and the flange bolt fastening assembly of the other side ear part is loosened, and the bearing cover plate 1 can be lifted to a certain angle to facilitate the removal of the spindle bearing 4 or the spindle 200, thereby improving the convenience of subsequent maintenance.

[0055] In the present invention, as a first specific embodiment, this embodiment is a snap-on spindle bearing 4, refer to the attached Figure 4-10 As shown, the spindle bearing 4 comprises two identical bearing components 41. Each component 41 includes a main body 42 with a snap-fit portion 43 at each end. The two components 41 can be interlocked via their respective snap-fit portions 43. The snap-fit portions 43 of the two components 41 are identical in structure. This standardized design makes the two components 41 interchangeable, eliminating the need for orientation identification, simplifying the production and assembly process, and improving installation efficiency. The inner surface of the main body 42 is defined by multiple weight-reducing holes 421.

[0056] In the present invention, the snap portion 43 includes a first snap unit 431 and a second snap unit 432. The first snap unit 431 includes a first connecting block 4311, a first clamping block 4312, and a first L-shaped hook groove 4313. The second snap unit 432 includes a second connecting block 4321, a second clamping block 4322, and a second L-shaped hook groove 4323. One side of the first connecting block 4311 and the first clamping block 4312 are integrally formed with the main body 42, and the other side is integrally formed with the second connecting block 4321. The projection of the second clamping block 4322 on the first snap unit 431 is located in the region of the first L-shaped hook groove 4313. The first snap unit 431, the second snap unit 432, and the main body 42 are integrally formed, enhancing the structural integrity of the snap portion 43, avoiding stress concentration caused by separate connections, and extending service life. The second clamping block 4322 is projected onto the first L-shaped hook groove 4313 , so that the second clamping block 4322 and the first clamping block 4312 can be staggered in the longitudinal direction, ensuring that the buckle portion 43 is precisely aligned and improving assembly reliability.

[0057] In the present invention, the surface of the first clamping block 4312 is sequentially formed with an oblique groove 4314, a first arcuate transition surface 4315, and a first oblique boss 4316. The oblique groove 4314 communicates with the first L-shaped hook groove 4313, and the oblique groove 4314 and the first L-shaped hook groove 4313 are disposed toward the exterior of the bearing sub-component 41. The surface of the second clamping block 4322 is sequentially formed with a flat groove 4324, a second arcuate transition surface 4325, and a second oblique boss 4326. The flat groove 4324 communicates with the second L-shaped hook groove 4323, and the flat groove 4324 and the second L-shaped hook groove 4323 are disposed toward the interior of the bearing sub-component 41. The outward communication between the oblique groove 4314 and the first L-shaped hook groove 4313 forms a guide channel, facilitating the sliding and positioning of the second clamping block 4322, thereby simplifying assembly. The flat groove 4324 and the inward connection of the second L-shaped hook groove 4323 form a complementary guide, which limits the lateral displacement of the snap-on portion 43, avoids movement after assembly, simplifies the assembly operation and significantly improves the reliability of the snap connection. The interference fit between the first inclined boss 4316 and the second inclined boss 4326 relies on the elastic deformation of the plastic to ensure a tight fit after buckling, without the need for additional fixings, reducing material costs. The inclined bosses and grooves are designed on the left and right ends of the bearing component 41, so that there is no need for additional bolts or other limiting parts. Only by deforming the plastic bearing material itself, the two bearing components 41 can be combined into a whole and the main shaft bearing 4 that will not move or fall off can be formed, thereby avoiding the rotational slippage between the bearing seat 2 and the main shaft 200. At the same time, it simplifies the installation steps, improves the convenience of disassembly and assembly, and saves material and labor costs.

[0058] In the present invention, the bearing component 41 is a plastic bearing component 41, which allows it to deform and achieve an interference fit. The bearing component 41 is made of plastic, which has self-lubricating properties, reducing friction loss and extending the operating life of the bearing seat 2 in the photovoltaic bracket. Plastic is also highly corrosion-resistant, adapting to complex outdoor environments and reducing maintenance frequency. The lightweight design reduces the overall weight of the bracket and reduces the load requirements on the supporting structure.

[0059] For ease of explanation, refer to the attached Figure 8-10 As shown, the snap-in spindle bearing 4 includes two first bearing components 41A and a second bearing component 41B with identical structures; the first bearing component 41A includes a first snap-in portion 43A and a second snap-in portion 43B; the second bearing component 41B includes a third snap-in portion 43C that cooperates with the first snap-in portion 43A and a fourth snap-in portion 43D that cooperates with the second snap-in portion 43B. The assembly process of the snap-on spindle bearing 4 of this embodiment is as follows: When the first snap-on portion 43A and the third snap-on portion 43C are assembled, there is an interference between the second inclined protrusion 4326 of the first snap-on portion 43A and the first inclined protrusion 4316 of the third snap-on portion 43C. Due to the elastic deformation of the plastic material, the sliding continues until the second arcuate transition surface 4325 of the first snap-on portion 43A slides over the first arcuate transition surface 4315 of the third snap-on portion 43C, at which point the interference disappears. At this point, the second inclined protrusion 4326 of the first snap-on portion 43A is highly aligned with the inclined groove 4314 of the third snap-on portion 43C, and the inclined groove 4314 of the first snap-on portion 43A is highly aligned with the second inclined protrusion 4326 of the third snap-on portion 43C. Similarly, the second snap-on portion 43B and the fourth snap-on portion 43D at the other end engage in the same manner. After engagement, the first and second bearing sub-components 41A and 41B are prevented from rotating relative to each other or moving left or right relative to each other. At the same time, the flat groove 4324 of the first snap-fit portion 43A does not fit with the first inclined boss 4316 of the third snap-fit portion 43C, and the first inclined boss 4316 of the first snap-fit portion 43A does not fit with the flat groove 4324 of the third snap-fit portion 43C, which can avoid the problem that if both places fit together, the joint surface of the bearing split will be too constrained and unable to be assembled.

[0060] As a second specific embodiment, the two plastic bearing components 41 are buckled together to form a snap-on spindle bearing 4; the outer surface of the snap-on spindle bearing 4 is spherical, and the spherical structure provides universal rotation capability to meet the multi-angle adjustment requirements of the photovoltaic tracking bracket; the smooth transition of the surface reduces stress concentration points and reduces the risk of cracking. Figure 11-12As shown, the snap-on spindle bearing 4 includes a first end face 6 and a second end face 7. A polygonal cavity 8 is formed on the first end face 6 toward the second end face 7, extending through the snap-on spindle bearing 4. The polygonal cavity 8 includes multiple flat surfaces 81, with adjacent flat surfaces forming an inner angle 82. The two plastic bearing components 41 are snapped together to form a polygonal cavity 8. The polygonal cavity 8 is adapted to the cross-sectional shape of the spindle 200, increasing the contact area and avoiding local wear caused by uneven pressure distribution. A first groove 821 is formed on the first end face 6 at the inner angle 82 of the polygonal cavity 8, and a second groove 822 is formed on the second end face 7 at the inner angle 82 of the polygonal cavity 8. A thick-walled area is formed between the flat surface 81 and the outer wall of the spherical snap-on spindle bearing 4; a thin-walled area is formed between the inner angle 82 and the outer wall of the spherical snap-on spindle bearing 4. The grooves on the end faces form an arc-shaped transition between the thick-walled and thin-walled areas. The first end face 6 and the second end face 7 are provided with grooves at the inner corners 82 (i.e., grooves are provided at the two ends of the thin-walled area). The grooves avoid the thin-walled area, disperse the stress at the inner corners, and significantly reduce the risk of cracking in the thin-walled area. Without increasing the cost and weakening the overall strength of the spherical main shaft bearing 4, the effective contact area between the snap-on main shaft bearing 4 and the main shaft 200 is guaranteed, and the problem of cracking in the overly thin area of the spherical main shaft bearing 4 is solved. At the same time, the design of multiple grooves makes the first end face 6 and the second end face 7 resemble petals as a whole. The two sides work together to make the two end faces of the spherical snap-on main shaft bearing 4 have a plum blossom opening shape. The plum blossom opening design maintains beauty while enhancing strength, taking into account both functionality and appearance. Preferably, the polygonal cavity 8 is any one of a regular octagonal cavity, a regular heptagonal cavity, a regular hexagonal cavity, a regular pentagonal cavity, and a regular quadrilateral cavity. The shape of the polygonal cavity 8 is any polygon or special shape, which is compatible with the shape of the main shaft 200. The remaining structure of the snap-in type spindle bearing 4 in this specific embodiment is the same as that of the snap-in type spindle bearing in the first specific embodiment, and also has a snap-in portion, which will not be described in detail.
