Description

Technical Field

[0001] This utility model relates to the field of lighting fixture technology, and in particular to a screwless LED light board structure. Background Technology

[0002] LED lighting fixtures, with their significant advantages such as high luminous efficiency, low energy consumption, long lifespan, and environmental friendliness, have become mainstream products in the modern lighting field, widely used in various indoor and outdoor lighting scenarios such as residential, office, commercial, industrial, and public buildings. They not only provide stable and uniform lighting effects, but also can meet the illuminance and color temperature requirements of different spaces through flexible optical design.

[0003] Currently, most LED light panels on the market are still installed using the traditional screw-locking method. Although this method is simple in structure and provides a secure connection, it usually requires tools and the assembly process is relatively cumbersome, making it difficult to meet the needs for rapid installation and efficient maintenance. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a screwless LED light board structure, which solves the problems of LED light board installation relying on tools and low assembly efficiency.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A screwless LED light board structure, comprising:

[0007] A connecting base is provided with a support platform and a locking structure; the support platform is provided with a hanging groove; the locking structure is connected to the support platform and supports the support platform; the locking structure is used to fix the connecting base to the wall.

[0008] The mounting base has a hook block that mates with the hook groove. The hook block slides horizontally into the hook groove and is supported by the hook groove.

[0009] The display light panel is mounted on the mounting base.

[0010] Furthermore, the locking structure is a suction cup structure.

[0011] Furthermore, the horizontal side view of the mounting groove has a C-shaped structure, and the horizontal side view of the mounting block has an inverted C-shaped structure. The mounting block and the mounting groove together form a heat dissipation cavity.

[0012] Furthermore, a screwless LED light board structure also includes a baffle, which is connected to and supported by the mounting base; the baffle has at least two pieces, which are respectively located on opposite horizontal sides of the heat dissipation cavity and cooperate to seal the heat dissipation cavity.

[0013] Furthermore, the baffle is provided with multiple ventilation holes, which penetrate the baffle along the wall thickness direction and connect the heat dissipation cavity to the outside.

[0014] Furthermore, the top of the hook block has an anti-tipping hanging plate, which covers the support platform. The support platform has an anti-tipping baffle, which prevents the anti-tipping hanging plate from detaching from the support platform.

[0015] Furthermore, the baffle is magnetically connected to the mounting base.

[0016] Furthermore, the mounting base has a pair of supporting bosses on its horizontally opposite sides, the supporting bosses being used to support the baffle.

[0017] Furthermore, the display panel is threadedly connected to the mounting base.

[0018] Furthermore, an elastic buffer pad is provided between the mounting base and the display light panel.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. The support platform is equipped with a mounting groove, and the mounting base has a mounting block that mates with the mounting groove. The mounting block slides horizontally into the mounting groove and is supported by the mounting groove. Therefore, the mounting base and the connecting base achieve rapid assembly through a dry sliding connection. Specifically, the mounting block is located on the side or bottom of the mounting base, and its shape matches the mounting groove on the connecting base. During installation, the construction personnel only need to push the mounting base horizontally so that the mounting block slides smoothly into the mounting groove until it is in place. At this time, the bottom support surface of the mounting groove bears the entire weight load of the mounting base and the display light panel it carries, while the groove wall provides horizontal restraint, effectively preventing it from falling out or shaking. This structural design achieves truly tool-free and screwless installation: no wrenches, electric drills, or fasteners are needed, greatly simplifying the on-site operation process, reducing the requirements for construction skills, and significantly improving assembly efficiency. While ensuring reliable connections and stable load-bearing capacity, this design not only shortens installation time and reduces labor costs, but also avoids the risk of long-term connection failures caused by loose bolts, stripped threads, or corrosion. Furthermore, the tight fit between the mounting groove and the mounting block creates a clear force transmission path, enabling efficient load transfer to the wall support structure while maintaining a clean appearance with no exposed fasteners. This enhances maintenance flexibility and structural integrity while balancing functionality and aesthetics. Attached Figure Description

[0027] See Figures 1-2 A preferred embodiment of the present invention provides a screwless LED light panel structure, comprising: a connecting base 1, a mounting base 2, and a display light panel 3. The connecting base 1 is provided with a support platform 11 and a locking structure 12; the support platform 11 is provided with a hanging groove 13; the locking structure 12 is connected to the support platform 11 and supports the support platform 11; the locking structure 12 is used to fix the connecting base 1 to a wall; the mounting base 2 has a hanging block 21 that cooperates with the hanging groove 13, the hanging block 21 sliding horizontally into the hanging groove 13 and being supported by the hanging groove 13; the display light panel 3 is mounted on the mounting base 2.

[0028] Before installing and activating a screwless LED light panel structure, thorough preliminary planning and structural evaluation should be conducted based on site wall conditions, installation height, maintenance convenience, and power supply and signal access requirements. First, fix the connector 1 to the predetermined wall position, ensuring a secure and reliable connection between the connector 1 and the wall using its locking structure 12. Then, align the mounting base 2 with the support platform 11 of the connector 1, allowing the hanging block 21 on the mounting base 2 to slide smoothly into the hanging groove 13 provided on the support platform 11 in a horizontal direction, until the hanging block 21 is fully in place and effectively supported by the bottom support surface of the hanging groove 13. Simultaneously, the groove wall provides horizontal restraint to prevent detachment or shaking. Next, install the display light panel 3 onto the mounting base 2, ensuring it is securely fixed and the electrical connection is normal. After installation, check the stability of the power supply and signal connection of the display light panel 3 to confirm the continuous and reliable electrical path during subsequent use. For maintenance or replacement of the light panel, simply slide the mounting base 2 out of the horizontal direction into the mounting slot 13 for quick removal without the need for any tools or fasteners.

[0029] The support platform 11 has a mounting groove 13, and the mounting base 2 has a mounting block 21 that mates with the mounting groove 13. The mounting block 21 slides horizontally into the mounting groove 13 and is supported by the mounting groove 13. Therefore, the mounting base 2 and the connecting base 1 are connected by a dry sliding connection to achieve rapid assembly. Specifically, the mounting block 21 is located on the side or bottom of the mounting base 2, and its shape matches the mounting groove 13 on the connecting base 1. During installation, the construction personnel only need to push the mounting base 2 horizontally so that the mounting block 21 slides smoothly into the mounting groove 13 until it is in place. At this time, the bottom support surface of the mounting groove 13 bears the entire weight load of the mounting base 2 and the display light panel 3 it carries, while the groove wall provides horizontal restraint, effectively preventing it from falling out or shaking. This structural design achieves truly tool-free and screwless installation: no wrenches, electric drills, or fasteners are needed, greatly simplifying the on-site operation process, reducing the requirements for construction skills, and significantly improving assembly efficiency. While ensuring reliable connections and stable load-bearing capacity, this design not only shortens installation time and reduces labor costs, but also avoids the risk of long-term connection failures caused by loose bolts, stripped threads, or corrosion. Furthermore, the tight fit between the mounting groove 13 and the mounting block 21 forms a clear force transmission path, enabling efficient load transfer to the wall support structure while maintaining a clean appearance with no exposed fasteners. This enhances maintenance flexibility and structural integrity while balancing functionality and aesthetics.

[0030] Preferably, in this embodiment, the locking structure 12 is a suction cup structure. This suction cup structure is typically made of highly elastic, highly sealing silicone or rubber material, capable of adhering tightly to smooth, dense wall surfaces such as glass, ceramic tiles, metal plates, or flat, sprayed walls. By manually pressing to expel air from the suction cup, a stable negative pressure suction force is formed, thereby firmly fixing the connecting seat 1 to the wall without the need for screws, expansion bolts, or other mechanical fasteners. Installation only requires aligning and pressing to complete the fixation; disassembly can be achieved by pulling the release ring or turning the vent valve to release the negative pressure, allowing for non-destructive and quick removal. This design not only significantly simplifies the installation and disassembly process but also completely avoids structural or decorative damage to the wall caused by drilling or nailing, making it particularly suitable for locations with high requirements for wall integrity and aesthetics, such as shopping mall windows, museums, high-end exhibition halls, hotel lobbies, and finely decorated residences. Furthermore, the suction cup structure supports multiple reuses and maintains good suction performance during long-term use, allowing the display device to flexibly adjust its position or replace modules according to usage needs. While providing sufficient tensile and shear strength, this solution balances installation reliability, ease of operation, and visual neatness, offering an efficient, safe, and aesthetically pleasing non-destructive installation solution for LED display modules or other wall-mounted devices in environments where drilling is not permitted or where surface protection is required.

[0031] Preferably, in this embodiment, the horizontal side view of the mounting groove 13 is C-shaped, and the horizontal side view of the mounting block 21 is an inverted C-shaped structure. The mounting block 21 and the mounting groove 13 together form a heat dissipation cavity 4. Although the heat dissipation cavity 4 is formed by C-shaped and inverted C-shaped structures, it is not completely sealed. Moderate ventilation channels can be retained at both ends or in parts, thereby ensuring dustproof performance while allowing natural air convection within the cavity. The heat generated by the display light panel 3 during operation can be conducted through the mounting base 2 to the metal or high thermal conductivity material structure of the mounting block 21 and the mounting groove 13, and then carried away by the airflow within the heat dissipation cavity 4, achieving passive heat dissipation. This design avoids the need to add an extra cooling fan or opening on the back of the light panel, simplifying the structure and improving the overall protection level. Because the mating surfaces of the mounting groove 13 and the mounting block 21 are tightly fitted, external dust, moisture, or foreign objects are difficult to penetrate into the heat dissipation cavity 4 and the interior of the light panel, effectively protecting the cleanliness and stability of electronic components and electrical connections. Meanwhile, the natural convection cooling method has no moving parts, operates quietly and requires no maintenance, and does not increase energy consumption, which helps to improve the stability and reliability of the equipment during long-term use. By designing the mounting slot 13 and the mounting block 21 as C-shaped and inverse C-shaped structures respectively, not only is a high-precision, anti-detachment mechanical connection achieved, but the gap between the two is also cleverly used to construct an integrated cavity that combines dustproof and heat dissipation functions. While improving the structural compactness and assembly efficiency, this significantly enhances the environmental adaptability, thermal management capability, and service life of the display panel 3.

[0032] Preferably, in this embodiment, the screwless LED light board structure further includes baffles 5, which are connected to and supported by the mounting base 2. There are at least two baffles 5, located on opposite horizontal sides of the heat dissipation cavity 4, working together to seal the heat dissipation cavity 4. The two baffles 5 work together to effectively seal the lateral openings of the heat dissipation cavity 4, forming a semi-enclosed thermal management space that is essentially isolated from the external environment in the horizontal direction. This design significantly enhances the integrity and protection level of the entire LED light board structure without relying on screws or adhesives. The baffles 5 not only provide lateral constraint and reinforcement to the mounting base 2 and the hanging components, improving overall rigidity, but also effectively prevent dust, moisture, insects, or small foreign objects from laterally invading the heat dissipation cavity 4, avoiding the accumulation of contaminants within the heat dissipation cavity 4 that could affect heat dissipation efficiency or corrode electronic components. This type of protection is crucial for ensuring the long-term stable operation of LED modules, especially in outdoor, semi-outdoor, or industrial environments. Meanwhile, the baffle 5 does not completely block the heat dissipation path. Instead, by designing the gap between it and the mounting base 2 or by creating a micro-pore array, it allows hot air to form natural convection within the cavity while blocking large particulate contaminants, thus promoting continuous and efficient heat dissipation. This design balances protection and heat dissipation performance, enabling the LED light panel to maintain a low operating temperature even under high brightness and long-term operation, delaying light decay and extending its service life.

[0033] Preferably, in this embodiment, the baffle 5 has multiple ventilation holes 51, which penetrate the baffle 5 along its wall thickness and connect the heat dissipation cavity 4 to the outside. These ventilation holes 51 are rationally arranged and sized to ensure sufficient cross-sectional area for airflow while effectively limiting the entry of larger dust particles, insects, or other foreign objects. Under natural convection or a gentle breeze, cooler external air can enter the heat dissipation cavity 4 through the lower or side ventilation holes 51, absorbing the heat generated by the display panel 3 during operation. The hot air is then discharged through the upper ventilation hole 51, thus forming a continuous and stable airflow circulation within the cavity. This design significantly improves passive heat dissipation efficiency while maintaining the basic sealing and protective performance of the heat dissipation cavity 4. By accelerating the air exchange between the inside and outside of the heat dissipation cavity 4, the operating temperature of the LED beads and driving circuit is effectively reduced, avoiding problems such as accelerated light decay, color drift, or aging of electronic components caused by heat accumulation. Especially under long-term high-brightness operation, good thermal management capabilities are crucial for ensuring the stability of the display effect and the reliability of the system. Since the entire structure does not require active cooling components such as fans, nor does it require additional openings or complex sealing treatments, it still maintains the modular advantages of being screwless, easy to maintain, and highly protected while achieving efficient heat dissipation.

[0034] Preferably, in this embodiment, the top of the hook block 21 has an anti-tipping inverted plate 22, which covers the support platform 11. The support platform 11 has an anti-tipping baffle 145, which prevents the anti-tipping inverted plate 22 from detaching from the support platform 11. After the hook block 21 slides into the hook groove 13 and is installed, the anti-tipping inverted plate 22 is located inside the anti-tipping baffle 145, and the two form a reliable mechanical interlocking relationship in the vertical and horizontal directions. This structure provides an additional safety barrier to prevent the hook block 21 from falling upwards or outwards, in addition to the conventional load-bearing and horizontal limiting functions. Even under extreme conditions such as strong wind suction, earthquake shaking, accidental collisions, or loose installation, the anti-tipping baffle 145 can effectively prevent the anti-tipping hanging plate 22 from detaching from the support platform 11, thereby preventing the hanging block 21 from completely slipping out of the hanging groove 13 and eliminating the risk of the display light panel 3 or the module it carries falling from a height. This design significantly improves the safety redundancy and structural stability of the entire hanging structure. Its function is not only reflected in the reliability of static load bearing, but also in the ability to resist failure under dynamic disturbances, ensuring that the LED light panel can still maintain its connection integrity under long-term use or sudden external force. At the same time, the anti-detachment mechanism is completely integrated into the main structure of the hanging block 21 and the support platform 11, without the need for additional fasteners or complex locks, which maintains the convenience of tool-free installation and achieves passive and highly reliable safety protection.

[0035] Preferably, in this embodiment, the baffle 5 is magnetically connected to the mounting base 2. Permanent magnets and magnetic materials can be respectively placed at corresponding positions on the baffle 5 and the mounting base 2, or magnets with matched polarities can be arranged on both, allowing the baffle 5 to automatically attract and position itself when it approaches the mounting base 2. This connection method eliminates the need for clips, screws, or plug-in structures; simply align the baffle 5 with the mounting position and gently place it, relying on magnetic force for a secure fit. Disassembly is also easy, requiring only moderate pulling force for easy separation, making the operation simple and efficient. This magnetic connection design significantly improves the convenience of maintenance and cleaning. When cleaning, repairing, or replacing internal components inside the heat dissipation cavity 4 is required, the user can quickly remove the baffle 5 without the need for tools or concerns about structural jamming, greatly shortening maintenance time. Simultaneously, since the magnetic connection is a non-contact mechanical coupling, it avoids structural wear, deformation, or fatigue failure caused by repeated insertion, removal, twisting, or friction in traditional mechanical connections, effectively extending the service life of the baffle 5 and the mounting base 2. Furthermore, the magnetic connection provides sufficient holding force to resist vibration and daily disturbances, while still ensuring that the baffle 5 has a certain buffering and release capability in the event of accidental impact, reducing the risk of damage caused by rigid collisions. The overall structure is simple and the appearance is clean, with no exposed fasteners, balancing functionality and aesthetics.

[0036] Preferably, in this embodiment, the mounting base 2 has a pair of supporting bosses 23 on its horizontally opposite sides, which are used to support the baffle 5. In actual use, since the locking structure 12 is usually vertically adsorbed and fixed to the wall, the entire lamp panel structure is in a state of suspension or subjected to lateral force. If the baffle 5 is fixed by magnetic connection alone, it is easy for the baffle 5 to slip, deviate or even fall off under the action of gravity, airflow disturbance or slight external force, which will result in the heat dissipation cavity 4 not being effectively sealed, affecting the dustproof performance, heat dissipation effect and overall structural stability of the product. To this end, this solution adds a pair of supporting bosses 23 as a mechanical support structure to provide reliable bottom support and lateral limit during the installation of the baffle 5. During assembly, the baffle 5 can be directly placed on the pair of supporting bosses 23, and the structure of the supporting bosses 23 is used to achieve horizontal centering and consistent height, ensuring that it fits tightly with the opening contour of the heat dissipation cavity 4. Based on this, the magnetic connection is mainly used to enhance the tightness of the fit between the baffle 5 and the mounting base 2 and to prevent detachment, while the main load-bearing and positioning functions are undertaken by the supporting boss 23. This design, which combines mechanical support and magnetic assistance, ensures both the stability and sealing of the connection while maintaining ease of installation and removal: during installation, simply align the baffle 5 with the supporting boss 23 and gently place it down, and the magnetic structure will automatically complete the fit; during removal, it can also be operated with one hand without the need for tools, significantly improving maintenance efficiency. In addition, the weight of the baffle 5 is directly transferred to the main body of the mounting base 2 through the supporting boss 23, avoiding long-term shear force or bending moment stress on the magnetic connection parts, effectively reducing the risk of performance degradation of magnetic components due to fatigue or aging, thereby improving the overall durability and long-term reliability of the structure.

[0037] Preferably, in this embodiment, the display lamp panel 3 is threadedly connected to the mounting base 2. Specifically, an internal threaded hole can be provided on the mounting base 2, and a matching external threaded post can be provided at the corresponding position on the display lamp panel 3 (or vice versa), forming a reliable detachable mechanical connection through screwing. This threaded connection structure not only ensures the firm fixation of the display lamp panel 3 on the mounting base 2, but also ensures its precise positional repeatability in three-dimensional space, effectively avoiding displacement or loosening caused by vibration, thermal expansion and contraction, or external disturbances. This connection method provides high mechanical strength while also creating favorable conditions for the stability of the electrical connection. Due to the self-locking and high contact pressure of the threaded connection, the grounding or signal circuit between the display lamp panel 3 and the mounting base 2 can maintain a low-impedance, high-reliability physical contact, which is especially suitable for high-density LED display systems with high requirements for electromagnetic compatibility or signal integrity. In addition, the preload of the threaded connection can effectively compress the thermal interface material, improve the heat conduction efficiency between the lamp panel and the mounting base 2, and assist in heat dissipation. This connection typically requires only a few points and, with the help of a pre-alignment structure, can still achieve efficient assembly. It also takes into account high-precision positioning, long-term stability, and reversible maintenance, making it particularly suitable for application scenarios with stringent requirements for display flatness, splicing accuracy, and operational reliability, such as stage rental screens, command centers, and broadcasting studios.

[0038] Preferably, in this embodiment, an elastic buffer pad is provided between the mounting base 2 and the display panel 3. This elastic buffer pad is typically made of silicone, rubber, polyurethane, or other flexible materials with excellent resilience and aging resistance, and is arranged at multiple key support points or the overall contact area between the back of the display panel 3 and the mounting base 2. When the display panel 3 is installed on the mounting base 2, the elastic buffer pad is moderately compressed, forming an intermediate interface that combines buffering, sealing, and leveling functions. This design effectively absorbs mechanical vibrations, impacts, or dynamic loads from the external environment or during transportation, avoiding stress concentration caused by rigid contact, thereby significantly reducing the risk of fatigue fracture or poor contact of LED beads, solder joints, or drive circuits due to repeated vibrations. Especially in applications such as outdoor installations, vehicle displays, stage rentals, or earthquake-prone areas, the elastic buffer pad provides important passive protection. Furthermore, due to unavoidable dimensional tolerances of components or minor unevenness of the mounting surface during manufacturing, rigid direct bonding can easily lead to localized warping, uneven seams, or uneven stress on the display panel 3, affecting overall flatness and visual consistency. The elastic buffer pad, with its compressibility and deformation adaptability, can automatically compensate for these minor deviations during the assembly process, so that the display panel 3 naturally fits into the ideal plane after being pressed, thereby ensuring that the surface height is consistent and seamless when multiple modules are spliced ​​together, and improving the uniformity and professionalism of the overall display effect.
