Description

Technical Field

[0001] This utility model relates to the field of photovoltaic manufacturing technology, specifically to a photovoltaic module fixing device. Background Technology

[0002] With the continuous development and technological advancements in the photovoltaic industry, new-generation frameless and lightweight photovoltaic modules have been widely adopted in the market. Their higher energy conversion efficiency and superior aesthetic integration have made them a mainstream trend. The market is demanding greater convenience and cost-effectiveness in installation methods, particularly for installations that require no processing or drilling.

[0003] In existing technologies, traditional fixed mounting methods generally rely on the module frame or specially reserved mounting holes for fixation. However, new frameless or frameless photovoltaic modules lack these traditional fixing supports, making traditional installation methods difficult to implement, affecting installation efficiency and system compatibility. Utility Model Content

[0004] In view of this, the present invention provides a photovoltaic module fixing device to solve the problem of low installation efficiency of photovoltaic modules without frames or without perforated frames in the prior art.

[0005] In a first aspect, this utility model provides a photovoltaic module fixing device, comprising:

[0006] The first pressure block has mounting holes and is adapted to be pressed and installed on one side of the photovoltaic module;

[0007] The second pressure block is adapted to be supported and installed on the other side of the photovoltaic module. The second pressure block is provided with a mating hole, which is aligned with the mounting hole.

[0008] The locking assembly includes a through fastener and an elastic adjustment member. The through fastener passes through the mounting hole and the mating hole in sequence and is then locked in place by a fixing member. The elastic adjustment member is abutted between the first pressure block and the second pressure block.

[0009] After the through fastener passes through the mounting holes of the first and second pressure blocks and locks in place, the elastic adjustment component is compressed, generating axial preload to clamp the photovoltaic module between the two pressure blocks. When the module is subjected to thermal expansion, mechanical vibration, or wind load, the elastic adjustment component continuously compensates for changes in module thickness through elastic deformation, maintaining a constant clamping force. The photovoltaic module fixing device achieves stable fixation of the photovoltaic module through the cooperation of the first and second pressure blocks and the connection of the locking component. The elastic adjustment component improves the adaptability of the device to photovoltaic modules of different thicknesses, buffers the impact of external factors such as wind vibration and thermal expansion and contraction on the photovoltaic module, extends the service life of the photovoltaic module, and improves the stability and reliability of the photovoltaic system. The continuous dynamic compensation capability of the elastic adjustment component eliminates the dependence on the frame structure or pre-set holes, enabling direct fixation of frameless modules; at the same time, by maintaining a constant clamping force, it effectively suppresses vibration transmission and avoids connection failure caused by loose pressure blocks; the photovoltaic module fixing device can adaptively accommodate various photovoltaic modules with multiple thicknesses and automatically absorbs installation tolerances through elastic deformation, preventing stress concentration damage caused by rigid contact.

[0010] In one optional embodiment, a limiting step is provided on at least one side of the first clamping block, and the photovoltaic module is adapted to abut against the bottom surface of the limiting step. When the photovoltaic module is placed under the first clamping block, the edge of the photovoltaic module abuts against the bottom surface of the limiting step, forming a physical barrier, and the vertical constraint surface of the limiting step restricts the lateral displacement of the module. Rigid limiting eliminates positional deviations during module installation, avoids edge damage caused by module slippage during clamping, ensures the module maintains its preset installation position under wind vibration, and ensures the stability of the photovoltaic module installation.

[0011] In one optional embodiment, a friction part is provided on the side of the limiting step that abuts against the photovoltaic module. The surface protrusion structure increases the coefficient of friction with the photovoltaic module surface. When a clamping force is applied through the fastener, the teeth of the friction part engage with the photovoltaic module surface to form an anti-slip lock. By supplementing the rigid limiting with friction constraint, double protection is provided to prevent micro-displacement of the photovoltaic module under extreme wind pressure, while avoiding stress concentration on the glass surface of the photovoltaic module caused by rigid clamping.

[0012] In one optional embodiment, the second pressure block is a shell structure. A self-locking groove is provided on the upper side plate of the second pressure block, and an overlapping member is provided on one side of the self-locking groove. Both the self-locking groove and the overlapping member are arranged along the extending direction of the edge of the photovoltaic module that mates with the second pressure block. The overlapping member abuts against the edge of the self-locking groove. The upper side plate of the second pressure block has a self-locking groove at its edge, and adjacent overlapping members extend to the lower side of the groove. When the photovoltaic module sags due to snow load, the upper side plate of the second pressure block tilts and deforms outward, causing the overlapping member to engage with the self-locking groove, forming a mechanical interlock. This prevents the photovoltaic module from detaching under extreme loads, providing additional safety assurance.

[0013] In one optional embodiment, a pad is installed over the self-locking slot, the upper surface of which is flush with the upper side of the second pressure block. The pad covering the self-locking slot and the upper side of the second pressure block form a continuous support plane; the pad disperses the localized pressure transmitted by the photovoltaic module, preventing stress concentration at the edges of the self-locking slot from causing deformation and failure. The pad protects the self-locking slot from external damage while maintaining the flatness of the upper side of the second pressure block, facilitating installation with the flat surface of the photovoltaic module.

[0014] In one optional embodiment, multiple support arms are spaced apart between the lower side plate and the upper side plate of the second pressure block to divide the space between the upper and lower side plates into multiple cavities. The upper and lower side plates of the second pressure block are connected by multiple support arms to form a grid-like cavity structure. The support arms provide support and cushioning, while the cavities reduce the weight of the second pressure block and provide a certain deformation space, enabling it to better absorb impact energy when subjected to external forces.

[0015] In one optional embodiment, a guide member is fixedly connected to the side of the first pressure block facing the second pressure block. The guide member extends towards and through the second pressure block. The guide member at the bottom of the first pressure block is vertically inserted into the rectangular hole of the second pressure block to form axial positioning. During installation, the guide member can guide the relative position of the first and second pressure blocks, ensuring accurate alignment and improving the convenience and accuracy of installation. It also ensures that the first and second pressure blocks remain coaxially aligned during locking, preventing buckling failure of the elastic adjustment member due to off-center loading, while limiting the horizontal rotational freedom of the first and second pressure blocks.

[0016] In one optional embodiment, the second pressure block has a drainage channel on the side facing the first pressure block. The drainage channel extends along the edge of the side where the photovoltaic module mates with the second pressure block, and both ends of the drainage channel extend through the second pressure block. During use, the drainage channel guides rainwater out, preventing rainwater from accumulating between the second pressure block and the photovoltaic module, thus avoiding corrosion of the photovoltaic module and the second pressure block by accumulated water.

[0017] In one optional embodiment, the elastic adjustment element is a columnar spring, which is sleeved and mounted on the through-fastener. During the locking process, the columnar spring provides elastic force to adapt to changes in the thickness of the photovoltaic module, ensuring a uniform distribution of clamping force, while buffering the impact of external factors on the photovoltaic module and extending its service life. Furthermore, the controllable deformation of the spring can absorb the thermal expansion and contraction of the module, maintaining a constant clamping force.

[0018] In one optional embodiment, the bottom surface of the first pressure block is provided with a spring mounting groove, and the columnar spring is abutted and installed in the spring mounting groove. The spring mounting groove can fix the position of the columnar spring, prevent it from shifting or shaking during use, and ensure the stability and reliability of the elastic adjustment component.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, 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, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] The following is combined with Figures 1 to 6 The following describes embodiments of the present invention.

[0029] According to an embodiment of the present invention, a photovoltaic module fixing device is provided, including a first pressing block 1, a second pressing block 2, and a locking component 3 for fixing the first pressing block 1 and the second pressing block 2.

[0030] The first pressure block 1 has an axially penetrating mounting hole 101, with its working surface facing the top surface of the photovoltaic module for applying clamping force. The second pressure block 2 has an axially penetrating mating hole 205, with its supporting surface facing the bottom surface of the photovoltaic module. The axis of the mating hole 205 is coaxially aligned with the axis of the mounting hole 101. The locking assembly 3 includes a through fastener 301 and an elastic adjustment member 302. The screw portion of the through fastener 301 passes sequentially through the mounting hole 101 of the first pressure block 1 and the mating hole 205 of the second pressure block 2, and is then tightened and locked by a fixing member. The elastic adjustment member 302 is installed in the compression space between the bottom surface of the first pressure block 1 and the top surface of the second pressure block 2, with both ends of the elastic adjustment member 302 abutting against the first pressure block 1 and the second pressure block 2, respectively.

[0031] When the through fastener 301 passes through the mounting hole 101 of the first pressure block 1 and the mating hole 205 of the second pressure block 2 and is locked by the fixing component, the elastic adjustment component 302 undergoes compressive deformation under the axial compression of the first pressure block 1 and the second pressure block 2, forming a constant pre-tight clamping force acting on the surface of the photovoltaic module 4. When the photovoltaic module undergoes thermal expansion due to changes in ambient temperature or is subjected to wind loads or mechanical vibrations, the elastic adjustment component 302 continuously compensates for changes in module thickness through real-time elastic expansion and contraction, maintaining the dynamic balance of the clamping force. Through the coordinated clamping action of the working surface of the first pressure block 1 and the supporting surface of the second pressure block 2, combined with the rigid constraint formed by the through fastener 301, the photovoltaic module is stably fixed in three-dimensional space. Based on the deformation capability of the elastic adjustment component 302, the device can be adapted to various photovoltaic modules with different thicknesses, and significantly reduces the structural damage to the module caused by wind vibration and thermal stress by continuously absorbing vibration energy. The adaptive mechanism of the elastic adjustment component 302 eliminates the need for the device to rely on the frame structure of the photovoltaic module or the preset mounting hole 101 position. At the same time, it automatically offsets the dimensional tolerances during the installation process, eliminates the local stress concentration caused by rigid contact, and fundamentally improves the long-term operational stability and structural reliability of the photovoltaic system.

[0032] In one embodiment, a limiting step 102 is provided on at least one side of the first pressing block 1, allowing the photovoltaic module to abut against the bottom surface of the limiting step 102. When installing the photovoltaic module, it is placed under the first pressing block 1, and the edge of the photovoltaic module naturally abuts against the bottom surface of the limiting step 102, forming a physical barrier. The vertical constraint surface of the limiting step 102 can restrict the lateral displacement of the photovoltaic module from the side, thereby providing precise positioning during installation. This rigid limiting structure can effectively eliminate positional deviations during module installation and prevent edge damage caused by module slippage during subsequent pressing block clamping. In long-term use, even under the influence of factors such as wind vibration, the module can always remain in the preset installation position, thereby ensuring the stability of the entire photovoltaic module installation system.

[0033] In this embodiment, the first pressing block 1 has a symmetrical structure, with limiting steps 102 symmetrically arranged on both sides for installation between two sets of photovoltaic modules, and for pressing and fixing the two sets of photovoltaic modules. In some other embodiments, the first pressing block 1 has a limiting step 102 on only one side, for installation on photovoltaic modules at the edge of the photovoltaic array.

[0034] In one embodiment, a friction part 103 is provided on the side of the limiting step 102 that abuts against the photovoltaic module. Specifically, the surface of the limiting step 102 that contacts the photovoltaic module has wavy protrusions extending parallel to the edge of the module. When the through fastener 301 is tightened, the protrusions form a frictional engagement with the module surface. The surface protrusions increase the coefficient of friction with the photovoltaic module surface. When the through fastener 301 applies a clamping force, the teeth of the friction part 103 engage with the photovoltaic module surface, forming an anti-slip lock. By supplementing the rigid limiting with frictional constraint, double protection is provided to prevent micro-displacement of the photovoltaic module under extreme wind pressure, while avoiding stress concentration on the glass surface of the photovoltaic module caused by rigid clamping. In some other embodiments, the wavy protrusions of the friction part 103 can be replaced with cross-grid patterns or other protrusion structures of arbitrary shapes.

[0035] In another embodiment, in order to reduce stress concentration caused by rigid contact, a flexible pad is provided between the photovoltaic module and the bottom surface of the limiting step 102 to adapt to the edge shape of the photovoltaic module.

[0036] In one embodiment, the second pressure block 2 adopts a shell structure. A self-locking groove 201 is provided on the upper side plate of the second pressure block 2, and an overlapping member 202 is also provided on one side of the self-locking groove 201. Both the self-locking groove 201 and the overlapping member 202 are arranged along the extending direction of the edge of the photovoltaic module that mates with the second pressure block 2, allowing the overlapping member 202 to abut against the lower edge of the self-locking groove 201. When the photovoltaic module dents due to snow load or other reasons, the upper side plate of the second pressure block 2 will tilt and deform outwards. At this time, the overlapping member 202 can smoothly engage with the self-locking groove 201, forming a robust mechanical interlock structure by further tilting the self-locking groove 201 upwards. This prevents the photovoltaic module from detaching under extreme load conditions, providing additional protection for the safe operation of the photovoltaic system.

[0037] In some other embodiments, the inner side of the self-locking slot 201 and the lower side of the overlapping member 202 can be designed as interlocking serrated structures, so that after the overlapping member 202 enters the self-locking slot 201, the strength and reliability of the mechanical interlock can be enhanced by the serrated structure.

[0038] In one embodiment, a pad is installed on the self-locking slot 201, with the upper surface of the pad flush with the upper side of the second pressure block 2. This creates a continuous support plane between the pad and the upper side of the second pressure block 2, which evenly distributes the local pressure transmitted from the photovoltaic module and prevents deformation failure due to stress concentration at the edge of the self-locking slot 201. The pad not only effectively protects the self-locking slot 201 from direct impact or damage from external objects but also maintains the flatness of the upper side of the second pressure block 2, allowing for a tighter fit with the photovoltaic module. To ensure the stability of the pad installation on the self-locking slot 201, a transverse groove is provided near the outlet of the self-locking slot 201 for installing the pad.

[0039] In another alternative embodiment, the pad can be made of an elastic material that can produce a certain elastic deformation when subjected to pressure, further buffering external impact forces and improving the stability and reliability of the entire photovoltaic module fixing device.

[0040] In one embodiment, the lower and upper side plates of the second pressure block 2 are spaced apart by multiple support arms 206, thereby dividing the space between the upper and lower side plates into multiple cavities. The multiple support arms 206 not only provide support, ensuring the relative stability of the upper and lower side plates, but also provide good cushioning performance. The cavities effectively reduce the weight of the second pressure block 2, while providing a certain deformation space for the second pressure block 2 when subjected to external impact, allowing it to better absorb impact energy and reduce damage to the photovoltaic module.

[0041] In one embodiment, a guide 104 is fixedly connected to the side of the first pressure block 1 facing the second pressure block 2. The guide 104 extends towards and passes through the second pressure block 2, and a pair of guides 104 are symmetrically arranged on both sides of the mounting hole 101. The guide 104 at the bottom of the first pressure block 1 is vertically inserted into the rectangular hole 204 of the second pressure block 2 to form axial positioning. During installation, the guide 104 can guide the relative position of the first pressure block 1 and the second pressure block 2, ensuring accurate alignment of the first pressure block 1 and the second pressure block 2, and improving the convenience and accuracy of installation. At the same time, it can also ensure that the first pressure block 1 and the second pressure block 2 are always coaxially aligned during the locking process, avoiding buckling failure of the elastic adjustment member 302 due to off-center load, and restricting the horizontal rotational freedom of the first pressure block 1 and the second pressure block 2. In this embodiment, the guide 104 is a rectangular column. In some other embodiments, the guide 104 can also be a cross-shaped column, a polygonal prism, or a cylinder.

[0042] In one embodiment, a drainage channel 203 is provided on the side of the second pressure block 2 facing the first pressure block 1. The drainage channel 203 extends along the edge of the side where the photovoltaic module mates with the second pressure block 2, and both ends of the drainage channel 203 extend through the second pressure block 2. In actual use, rainwater can be quickly discharged through the drainage channel 203, effectively preventing rainwater from accumulating between the second pressure block 2 and the photovoltaic module. This avoids water accumulation causing corrosion to the photovoltaic module and the second pressure block 2, extending the service life of the entire photovoltaic module fixing device.

[0043] In one embodiment, the elastic adjustment element 302 is a columnar spring, which is sleeved and mounted on the through fastener 301. During the locking process, the columnar spring provides reliable elastic force, automatically adapting to changes in the thickness of the photovoltaic module and ensuring that the clamping force is evenly distributed across the entire surface of the photovoltaic module. Simultaneously, the elastic characteristics of the columnar spring effectively buffer the impact of external factors such as wind vibration and thermal expansion and contraction on the photovoltaic module, thereby extending the service life of the photovoltaic module. Furthermore, the columnar spring can absorb the deformation of the photovoltaic module caused by thermal expansion and contraction through its controllable deformation, maintaining a stable clamping force. In other embodiments, the elastic adjustment element 302 can be made of rubber springs or other materials with similar elasticity to meet the elasticity requirements under different environmental conditions.

[0044] In this embodiment, a spring mounting groove 105 is provided on the bottom surface of the first pressure block 1, and a columnar spring is abutted and installed in the spring mounting groove 105. The spring mounting groove 105 can limit the position of the columnar spring and prevent the columnar spring from shifting or shaking during use. This ensures the stability and reliability of the elastic adjustment member 302 in long-term use and avoids the problem of uneven clamping force caused by spring position displacement.

[0045] The photovoltaic module fixing device provided in this embodiment mainly consists of a first pressure block 1, a second pressure block 2, a pad, an elastic adjustment component 302, a bolt as a through fastener 301, and a nut that cooperates with the bolt to lock it in place. The first pressure block 1 has a corrugated protrusion serving as a friction part 103, with a corrugated tooth pattern on its surface to increase friction with the back of the photovoltaic module, effectively preventing the module from sliding off. The lower sidewall of the upper limit step 102 of the first pressure block 1 contacts the edge of the photovoltaic module, providing lateral restraint and preventing lateral displacement of the module. The fixing post at the bottom of the first pressure block 1, serving as a guide 104, cooperates with the rectangular hole 204 of the second pressure block 2 to assemble the first upper pressure block and the second pressure block 2 into a single unit. A mounting hole 101 is provided through the first pressure block 1 for inserting bolts to fix the entire fixing device to the mounting bracket. A spring mounting groove 105 is provided on the bottom surface of the first pressure block 1, which is concentric with the mounting hole 101 to accommodate and fix the spring, preventing the spring from sliding or shifting during use and ensuring that the pressure block is subjected to uniform force. On the upper side plate of the second pressure block 2, the self-locking groove 201 and the overlapping member 202 constitute the core of the ultimate self-locking mechanism. When encountering extreme weather such as blizzards, if the middle of the photovoltaic module is subjected to excessive load and dents, the two sides of the second pressure block 2 will tilt and deform outward. When the deformation reaches a certain degree, the self-locking groove 201 tilts downward, causing the overlapping member 202 to engage in the self-locking groove 201, forming a mechanical self-lock. This mechanism can prevent the module from completely detaching from the pressure block when the middle of the module is damaged or subjected to ultimate load, providing important safety protection and preventing the module from being blown away by strong winds. The spring provides elastic preload, allowing the clamping block to adapt to components of varying thicknesses and ensuring clamping force. Under wind vibration, thermal expansion and contraction, or minor external forces, it allows for slight vertical and horizontal movement between the clamping block and the component, absorbing impact energy, effectively mitigating vibration transmission, and preventing damage caused by stress concentration or fatigue. It maintains relative stability of the frictional force between the component and the clamping block, preventing loosening caused by long-term vibration and extending the clamping block's service life.

[0046] This invention, through an innovative fixed clamping block structure design, combined with a spring buffer mechanism and a self-locking mechanism for the clamping block's load-bearing components, effectively solves the dependence on frames and holes in traditional installation methods. This improves the adaptability, installation efficiency, system safety, and long-term vibration stability of frameless and ultra-thin photovoltaic modules. Compared to existing technologies, the fixed clamping block installation method provided by this invention requires no machining; it eliminates the need for drilling holes or other processing on the photovoltaic module's frame or glass backplate, avoiding damage to the module body, simplifying the installation process, significantly improving installation efficiency, reducing labor costs, and enhancing the safety and reliability of the installation process. Installation is convenient and stable, employing a simple fixed structure design with an elastic rebound locking mechanism, making installation easy and requiring no complex tools. It also provides reliable clamping force, ensuring the stability of the module during long-term operation. Subsequent maintenance, disassembly, and replacement are equally convenient, saving maintenance costs. Adaptable to all thicknesses and shapes, the clamping block structure allows it to clamp lightweight modules of different thicknesses or frameless modules without holes, making it widely applicable. A single design can be adapted to both traditional and new photovoltaic modules, eliminating the need for precise alignment of holes, reducing installation difficulty and the risk of module damage, and greatly expanding application scenarios. High vibration stability is achieved through built-in springs that effectively absorb and buffer dynamic loads and minor displacements caused by wind vibration, thermal expansion and contraction, maintaining stable clamping force and preventing loosening of the clamping blocks and connection failure due to long-term vibration, ensuring stable operation of the modules in various environments. The integrated connection enhances wind resistance with a double-sided clamping block design that firmly connects adjacent modules. The entire row of modules is connected into a whole through multiple clamping blocks, significantly improving the wind resistance safety factor of the photovoltaic array. The structure is simple, the principle is mature, and it is easy to manufacture and maintain. Ultimate self-locking safety protection, with a unique self-locking slot 201 and overlapping piece 202 forming a self-locking mechanism, is a key advantage. In extreme loads such as severe downward bending of the module due to snow pressure causing deformation of the lower clamping block, this mechanism automatically triggers and locks, forming a mechanical lock. Even if the module is partially damaged, it effectively prevents the module from completely detaching from the clamping block or being blown away by strong winds, providing crucial passive safety protection.
