Description

Technical Field

[0001] This utility model belongs to the field of solar photovoltaic panel technology, specifically relating to a TOPCon battery module. Background Technology

[0002] TOPCon solar cell modules are high-efficiency solar cell modules that employ tunnel oxide passivation contact technology and are a core component used in the manufacture of photovoltaic panels.

[0003] Traditional solar panels typically rely on external aluminum frames for protection. During the edge-press installation of solar panels, the frame is the main stress point. If the edge pressure is not adjusted properly, such as being too loose, it will lead to insecure fixing and the risk of falling off. On the other hand, if the edge pressure is too tight, it will cause the frame to deform, resulting in uneven stress on the solar panel and causing microcracks between the solar panels. Microcracks not only reduce the energy conversion efficiency of the solar cells, leading to a decline in the overall performance of the solar panel and a reduction in the output power, but may also increase stress concentration points in the material, making certain parts of the solar panel more susceptible to damage, thus affecting its long-term stability and service life.

[0004] Therefore, in order to address the aforementioned technical problems, it is necessary to provide a TOPCon battery module. Utility Model Content

[0005] The purpose of this invention is to provide a TOPCon battery module that can solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution provided by a specific embodiment of this utility model is as follows:

[0007] A TOPCon battery assembly includes a battery body. A protective assembly is installed on the outside of the battery body. The protective assembly includes protective corners. One side of each protective corner has a mounting groove that matches the battery body. There are four protective corners, which are respectively installed at the four corners of the battery body. An mounting strip is installed on the side away from the battery body between two adjacent sets of protective corners. Several first bolts are symmetrically installed at both ends of the mounting strip. The end of the first bolt away from the mounting strip is threaded into the protective corner. The mounting strip is provided with a side pressure groove for accommodating side pressure. A reinforcing assembly is installed on the protective assembly. The reinforcing assembly includes a support plate. A connecting block is installed on the end of the support plate near the protective corner. A connecting groove for connecting the support plate is opened on the inner side of the protective corner.

[0008] In one or more embodiments of this utility model, a second rubber pad is installed on the side of the support plate near the battery body.

[0009] In one or more embodiments of this utility model, the support plate is an aluminum alloy sheet.

[0010] In one or more embodiments of this utility model, an anti-shrinkage strip matching the adjacent protective corner is installed on the top of the mounting strip, and a first rubber pad matching the battery body is installed on the side of the anti-shrinkage strip away from the mounting strip.

[0011] In one or more embodiments of this utility model, a plurality of connecting holes are evenly provided on the mounting strip, and a second bolt is installed in the corresponding connecting hole of an adjacent mounting strip.

[0012] In one or more embodiments of this utility model, a third rubber pad matching the battery body is installed on the side of the protective corner near the battery body.

[0013] In one or more embodiments of this utility model, side protective strips are installed on both sides of the protective corner, and limit components are installed between adjacent side protective strips of different protective corners, with the side protective strips closely attached to the outer edge of the battery body.

[0014] In one or more embodiments of the present invention, the limiting component includes a connecting piece, and the adjacent side protective strip has a groove matching the connecting piece at one end near the connecting piece.

[0015] In one or more embodiments of this utility model, a locking block is installed at one end of the connecting piece near the groove, and a locking groove matching the locking block is opened at one end of the adjacent side protective strip near the locking block.

[0016] In one or more embodiments of this utility model, an elongated groove matching the battery body is provided on the inner side of the side protection strip, and a fourth rubber pad matching the battery body is installed on the inner side of the side protection strip.

[0017] Compared with existing technologies, the TOPCon battery assembly of this invention utilizes the mounting strip as the main stress point for edge pressing, tightening the edge pressing as much as possible. This avoids the possibility of the edge pressing being too loose, which could lead to the battery body falling off due to insecure fixing. At the same time, the mounting strip is the main stress point, which also avoids the possibility of the battery body deforming due to excessive edge pressing. This ensures that the battery body is subjected to uniform force, effectively preventing the formation of microcracks between battery bodies, which would lead to a decrease in the energy conversion efficiency and overall performance of the battery body. This ensures that the power output of the battery body is normal, and ensures the long-term stability and service life of the battery body. Attached Figure Description

[0026] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0027] like Figure 1As shown, a TOPCon battery assembly according to one embodiment of this utility model includes a battery body 1, a protective component mounted on the outside of the battery body 1, and a reinforcing component mounted on the protective component. The protective component is used to withstand the force from edge pressure, thereby avoiding excessive edge pressure that could cause deformation of the battery body 1's frame, internal cracks in the battery body 1, resulting in a decrease in the overall performance and lifespan of the battery body 1. The reinforcing component is used to support the bottom of the battery body 1, preventing the battery body 1 from bending downwards under gravity, thus avoiding internal cracks and damage to the battery body 1.

[0028] like Figures 1-2 As shown, the protection assembly includes protection corners 201. Each protection corner 201 has a mounting groove on one side that matches the battery body 1. There are four protection corners 201, which are respectively installed at the four corners of the battery body 1. An mounting strip 202 is installed on the side of each pair of adjacent protection corners 201 away from the battery body 1. Several first bolts 203 are symmetrically installed at both ends of the mounting strip 202. The end of each first bolt 203 away from the mounting strip 202 is threaded into the protection corner 201. The mounting strip 202 has an edge pressure groove 2025 for accommodating edge pressure. After installing the protection corners 201 to the four corners of the battery body 1 using the mounting grooves, the mounting strip 202 is installed onto the adjacent protection corners 201 using the first bolts 203. When the user installs the battery body 1 using edge pressure, one end of the edge pressure is hooked onto the mounting strip 202 using the edge pressure groove 2025, thus achieving the installation of the battery body 1.

[0029] The mounting strip 202 is equipped with a receiving groove (not shown in the figure) that matches the head of the first bolt 203.

[0030] like Figures 2-4 As shown, the reinforcement component includes a support plate 301. A connecting block 302 is installed at one end of the support plate 301 near the protective corner 201. A connecting groove 2011 for connecting the support plate 301 is provided on the inner side of the protective corner 201. During the installation of the protective corner 201, the user assembles the support plate 301 to the bottom of the battery body 1 using the connecting block 302, thereby providing support and protection for the bottom of the battery body 1.

[0031] like Figures 3-4 As shown, a second rubber pad 303 is installed on the side of the support plate 301 near the battery body 1. This pad is used to protect the bottom surface of the battery body 1 and minimize wear on the surface of the battery body 1, thus affecting its normal use. When insects or birds fall onto the surface of the battery body 1, the second rubber pad 303 can absorb the impact force, reducing damage to the battery body 1 to a certain extent.

[0032] like Figures 1-4 As shown, the support plate 301 is made of aluminum alloy. The aluminum alloy material has a certain supporting force, thus enabling it to better support the battery body 1.

[0033] like Figures 2-4 As shown, an anti-shrinkage strip 2021 matching the adjacent protective corner 201 is installed on the top of the mounting strip 202. A first rubber pad 2022 matching the battery body 1 is installed on the side of the anti-shrinkage strip 2021 away from the mounting strip 202. The two ends of the anti-shrinkage strip 2021 support the two adjacent protective corners 201 respectively. When an external force causes the battery body 1 to bend and the protective corners 201 to move closer to each other, the anti-shrinkage strip 2021 supports the adjacent protective corners 201, preventing the battery body 1 from bending as much as possible, thereby protecting the battery body 1.

[0034] like Figure 5 As shown, a plurality of connecting holes 2023 are evenly provided on the mounting strip 202, and a second bolt 2024 is installed in the corresponding connecting hole 2023 of adjacent mounting strips 202. The second bolt 2024 is installed between adjacent mounting strips 202 with the edge pressed out of place, which improves the firmness of the battery body 1 installation to a certain extent.

[0035] like Figures 2-4 As shown, a third rubber pad 2012 matching the battery body 1 is installed inside the protective corner 201 on the side closest to the battery body 1. The third rubber pad 2012 contacts the battery body 1, thereby protecting the battery body 1.

[0036] like Figures 1-4 As shown, side protective strips 204 are installed on both sides of the protective corner 201. Limiting components are installed between adjacent side protective strips 204 connected to different protective corners 201, and the side protective strips 204 are in close contact with the outer edge of the battery body 1. Under the action of the limiting components, the adjacent side protective strips 204 connected to different protective corners 201 form a side plate that is in close contact with the outer edge of the battery body 1, protecting the side of the battery body 1.

[0037] like Figure 4 As shown, the limiting component includes a connecting piece 2041, and a groove 2042 matching the connecting piece 2041 is provided at one end of the adjacent side protective strip 204 near the connecting piece 2041. The connecting piece 2041 and the groove 2042 cooperate to limit the opposite side protective strip 204.

[0038] like Figure 4 As shown, a locking block 2045 is installed at one end of the connecting piece 2041 near the groove 2042, and a slot 2046 matching the locking block 2045 is provided at one end of the adjacent side protective strip 2044 near the locking block 2045. The locking between the locking block 2045 and the slot 2046 further improves the stability of the connection between the adjacent side protective strips 204.

[0039] like Figure 4As shown, the inner side of the side protection strip 204 has an elongated groove 2043 that matches the battery body 1, and a fourth rubber pad 2044 that matches the battery body 1 is installed on the inner side of the side protection strip 204. The fourth rubber pad 2044 is in close contact with the outside of the battery body 1, thereby protecting the side wall of the battery body 1.

[0040] like Figure 1 As shown, the top surface of the protective corner 201 is provided with a strip groove that matches the mounting strip 202. When the battery body 1 needs to be stacked during transportation, the battery body 1 is prevented from being misaligned and collided, thus avoiding damage to the battery body 1.

[0041] During use, the protective corners 201 are installed at the four corners of the battery body 1, and the mounting strips 202 are installed between adjacent protective corners 201 using the first bolts 203 to protect the four corners of the battery body 1. At the same time, the mounting strips 202 are used to install the edge pressure to fix the battery body 1, which is less likely to cause instability of the battery body 1 due to concerns about deformation of the battery body 1 and excessively tight edge pressure, or damage to the battery body 1.

[0042] During the sequential installation of the protective corner 201, the user installs the support plate 301 to the bottom of the battery body 1 using the connecting block 302 and the connecting groove 2011, thereby supporting the battery body 1 and effectively preventing the battery body 1 from bending downwards under the action of gravity or external force, thus avoiding damage to the battery body 1.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
