Description
Technical Field
[0001] This utility model relates to the field of photovoltaic module installation technology, and in particular to an anti-overflow adhesive structure for photovoltaic panel installation. Background Technology
[0002] In photovoltaic power generation systems, photovoltaic panels typically need to be connected to a junction box or similar housing containing electronic components (such as diodes, terminals, etc.). To achieve long-term reliable sealing, waterproofing, dustproofing, and mechanical fixation, potting compound is usually used to bond and seal the photovoltaic panels to the housing.
[0003] In actual production, achieving 100% precision in the glue application process is difficult. If too much glue is applied, the excess glue will overflow either outwards or inwards when the photovoltaic panel is pressed onto the casing. Outward overflow will contaminate the exterior of the casing, affecting the product's appearance; inward overflow may flow into the electronic component area, affecting its performance or even causing short circuits, creating safety hazards. If too little glue is applied, a complete and effective seal cannot be formed, reducing product reliability.
[0004] In addition, in order to reduce costs and weight, these housings are usually made of plastic and designed to be relatively thin. This may result in poor flatness or insufficient strength of the housing itself, making it prone to deformation during pressing and long-term use, which further affects the sealing effect.
[0005] Therefore, how to design a structure that can effectively accommodate overflowing glue while enhancing the structural strength of the shell itself is a technical problem that urgently needs to be solved in this field. Utility Model Content
[0006] The purpose of this invention is to provide an anti-overflow adhesive structure for photovoltaic panel installation, which aims to solve the problems of easy glue overflow and pollution during glue pouring and insufficient flatness and strength of the shell in the prior art.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] An anti-overflow adhesive structure for photovoltaic panel installation includes: a housing; the housing is rectangular and has a retaining edge along its edge; an overflow adhesive channel, the overflow adhesive channel being disposed along the inner side of the retaining edge; an adhesive channel, the adhesive channel being disposed along the inner side of the overflow adhesive channel; an installation grid, the installation grid being disposed in the middle region of the housing, and the bottom of the installation grid being provided with at least one through hole; and a plurality of overflow adhesive grids, the plurality of overflow adhesive grids being disposed between the adhesive channel and the installation grid, and surrounding the installation grid.
[0009] With the above technical solution, during the glue-filling operation, glue is injected into the glue tank. When the photovoltaic panel is pressed onto the casing, the glue in the tank flows to both sides under pressure. Glue overflowing outwards (near the edge) enters and is contained in the overflow groove; glue overflowing inwards (near the mounting grid) enters and is contained in multiple overflow grids. This bidirectional overflow guidance design effectively prevents glue from contaminating the external or internal electronic components of the casing, greatly improving the tolerance of glue filling and production yield.
[0010] Preferably, the plurality of glue overflow grids are formed by multiple ribs extending vertically upward on the bottom surface of the housing. These ribs not only serve to separate the glue overflow grids, but more importantly, they act as reinforcing ribs, significantly improving the flatness of the bottom of the housing and the overall structural rigidity, preventing deformation of the housing during installation or use.
[0011] Preferably, the multiple ribs and the shell are integrally formed. This design simplifies the manufacturing process, such as through one-time injection molding, reducing manufacturing costs while ensuring structural consistency and strength.
[0012] Preferably, the bottom surface of the glue overflow tray is lower than the bottom surface of the glue tank. This height difference, utilizing gravity, helps guide the overflowing glue smoothly into the overflow tray, improving the efficiency and reliability of the overflow.
[0013] Preferably, the bottom height of the plurality of glue overflow grids is the same as the bottom height of the glue tank. This is a structural solution that is easy to process and design, and can also effectively accommodate glue overflowing inward.
[0014] Preferably, the bottom surface of the mounting grid is raised by the surrounding wall, making the bottom surface of the mounting grid higher than the bottom surface of the plurality of glue overflow grids. This design provides a second layer of physical protection for electronic components in addition to the glue overflow grids. Even if the glue overflowing inward fills the glue overflow grids, the raised wall can effectively prevent the glue from further seeping into the mounting grid, further ensuring the safety of the electronic components.
[0015] Preferably, the adhesive groove is a continuous channel surrounding the plurality of adhesive overflow grids. The continuous adhesive groove ensures that a complete and uninterrupted sealing ring can be formed after the photovoltaic panel is pressed together, thereby guaranteeing the best waterproof and dustproof sealing effect.
[0016] Furthermore, to facilitate the installation and deployment of the entire structure, the anti-overflow adhesive structure also includes a support unit. The support unit comprises a support base, a chassis, and a connector. The chassis is fixedly mounted at one end of the support base, and the connector is fixedly mounted at the other end of the support base. The connector is fixedly equipped with a threaded connection, which connects to the back of the housing. This support unit provides a standardized installation interface, allowing the entire photovoltaic module to be easily fixed in the required location.
[0017] As a preferred solution particularly suitable for portable or temporary installation scenarios, the chassis is a suction cup. Using a suction cup as the chassis allows the entire device to be quickly and non-destructively adhered to smooth surfaces such as glass, smooth metal plates, and car roofs, without the need for drilling or the use of permanent adhesives, greatly expanding the product's application scenarios and convenience.
[0018] The beneficial effects of this utility model are as follows:
[0019] Two-way overflow prevention and high fault tolerance: By setting overflow troughs and overflow grids on both the inner and outer sides of the glue tank, overflow caused by excessive glue is effectively managed, avoiding contamination of the product appearance and internal components, and simplifying the requirements for glue dispensing accuracy.
[0020] Reinforced structure and reliable performance: The ribs that separate the glue overflow grids are used as reinforcing ribs, which cleverly improves the flatness and mechanical strength of the shell, ensuring a tight fit when pressed with the photovoltaic panel and long-term reliability.
[0021] Ingenious design and comprehensive protection: The compact structure combines overflow prevention with structural reinforcement. The height difference design further optimizes adhesive flow and protects core components.
[0022] Easy to install and widely applicable: By adding detachable support parts, especially by adopting a suction cup chassis solution, the installation of the entire photovoltaic module becomes exceptionally simple and quick, and can adapt to various temporary or mobile application needs.

Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art will be able to understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0030] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0031] Please see Figure 1 as well as Figure 2 This invention provides an anti-overflow adhesive structure for photovoltaic panel installation. The structure includes an integral housing (1). In this embodiment, the housing (1) is rectangular, but it can also be designed into other shapes according to actual needs.
[0032] Along the four edges of the housing (1), there are integrally formed upward protruding flanges (2). These flanges (2) form the outer contour of the structure and play a preliminary positioning role when installing photovoltaic panels.
[0033] An annular overflow groove (3) is provided on the inner side of the retaining edge (2). The overflow groove (3) is used to collect and contain the glue that overflows from the glue tank (4). In a preferred embodiment, the bottom surface of the overflow groove (3) can be designed to be lower than the bottom surface of the glue tank (4) so that the overflowing glue can be better guided into it by gravity.
[0034] Inside the overflow groove (3), there is a ring-shaped glue groove (4). The glue groove (4) is the main area for glue filling operation. In this embodiment, the glue groove (4) is a continuous groove surrounding the internal structure to ensure that a complete and uninterrupted sealing line can be formed after pressing with the photovoltaic panel.
[0035] In the central region of the housing (1), there is a mounting grid (5) for placing electronic components. The bottom of the mounting grid (5) has one or more through holes (6) for allowing external wires to pass through and make electrical connections with the electronic components installed inside the mounting grid (5). In a preferred embodiment, the mounting grid (5) is surrounded by walls, and its bottom surface is raised by these walls to be higher than the bottom surface of the surrounding adhesive overflow grids (7), thereby forming a separate, protected area.
[0036] The key structure of this design is that multiple overflow grids (7) are provided between the glue tank (4) and the mounting grid (5). These overflow grids (7) are separated by multiple ribs (8) and surround the central mounting grid (5) as a whole. These ribs (8) extend vertically upward from the bottom surface of the shell (1) and are preferably integrally injection molded with the shell (1).
[0037] The working process of this utility model is as follows:
[0038] 1. Before assembly, inject an appropriate amount of potting compound into the annular glue tank (4).
[0039] 2. Cover the photovoltaic panel onto the housing (1) and press it down.
[0040] 3. During the pressing process, the glue in the glue tank (4) is squeezed, the liquid level rises and flows to both sides.
[0041] 4. Some of the glue will flow over the outer wall of the glue tank (4) and toward the edge of the shell (1). At this time, this part of the glue will flow directly into and be collected in the overflow tank (3) instead of flowing out of the baffle (2) and contaminating the outside of the shell.
[0042] 5. Another portion of the glue will flow over the inner wall of the glue tank (4) towards the center of the housing (1). At this time, this portion of glue will flow into the multiple overflow grids (7) separated by the ribs (8). Since the overflow grids (7) have a certain volume, they can completely contain this portion of overflowing glue, thereby preventing the glue from flowing into the central mounting grid (5) and protecting the electronic components.
[0043] 6. At the same time, the multiple ribs (8) that serve as the separation structure of the glue overflow grid (7) form a grid-like reinforcing structure inside the shell (1), which greatly improves the bending resistance and overall flatness of the shell (1), ensuring that the photovoltaic panel and the shell (1) can fit flat and tightly, and ensuring the long-term reliability of the seal.
[0044] In summary, this utility model has successfully solved the problems raised in the background art by cleverly setting up a two-way overflow management structure (overflow groove (3) and overflow grid (7)) and using the ribs (8) that separate the overflow grid to enhance the mechanical properties of the shell (1). It has the characteristics of simple structure, integrated function and strong practicality, and is very suitable for large-scale industrial production.
[0045] Please see Figure 3 To improve the ease of installation of the entire component, this embodiment also provides a support part (9). The support part (9) is a component independent of the housing (1) and is connected to the housing (1) in a detachable manner, thereby giving the entire device greater adaptability.
[0046] Specifically, the support (9) includes a support base (91) as the main body. At one end of the support base (91), such as the lower end, a chassis (92) is fixedly installed. The chassis (92) is the part of the entire device that contacts the external mounting surface. At the other end of the support base (91), such as the upper end, a connector (93) is fixedly installed.
[0047] The connector (93) is used to connect the support (9) to the housing (1). For reliable and convenient connection, a threaded connector (931), such as an external threaded screw, is fixedly provided on the connector (93). Correspondingly, a matching internal threaded hole (not shown) is pre-set at the center of the back of the housing (1) (i.e., the side away from the photovoltaic panel installation). During installation, the support (9) can be firmly fixed to the housing (1) simply by screwing the threaded connector (931) into the threaded hole on the back of the housing (1). This threaded connection method is not only strong, but also facilitates the removal of the support (9) when needed.
[0048] In a particularly preferred embodiment, to meet the needs of portable and temporary use, the chassis (92) is designed as a suction cup. The suction cup (92) can be made of an elastic material such as rubber or silicone. In use, simply pressing the suction cup (92) onto a smooth, flat surface such as vehicle glass, a smooth metal casing, or a building window will quickly and stably fix the entire device in place using atmospheric pressure. When relocation or storage is required, the suction cup can be easily removed by lifting its edge without causing any damage to the mounting surface.
[0049] In summary, this utility model successfully solves the problems raised in the background art by cleverly setting up a bidirectional overflow management structure (overflow groove (3) and overflow grid (7)) and using ribs (8) to separate the overflow grid to enhance the mechanical properties of the shell (1). At the same time, by adding a detachable support part (9), especially a suction cup type chassis (92), the application range of the product is greatly expanded, making it not only suitable for traditional fixed installation, but also having significant advantages in portable solar charging, outdoor activities, temporary power supply and other fields.
[0050] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
