Description

Technical Field

[0001] This invention relates to the field of outdoor advertising light box technology, and in particular to a photovoltaic direct-drive energy storage outdoor advertising light box. Background Technology

[0002] Outdoor advertising light boxes are an important advertising medium, widely used in public places such as roadsides, streets, stations, airports, and commercial areas.

[0003] Existing outdoor advertising light boxes have relatively simple waterproof structures, typically only featuring a waterproof panel or rain shield on the top. However, in actual use, this is insufficient to effectively prevent rainwater from entering. Over time, rainwater seeps into the light box, causing moisture damage to internal light-emitting components and circuitry, severely impacting the light box's lifespan.

[0004] While some existing solar-powered advertising light boxes feature adjustable photovoltaic panel angles, the adjustment mechanisms are often complex and inconvenient to operate. Some adjustment mechanisms employ automatic adjustment methods such as motor drives, which are costly.

[0005] Therefore, there is an urgent need for an outdoor advertising lightbox that combines good waterproof sealing performance, efficient photovoltaic direct-drive energy storage power supply, and flexible adjustable photovoltaic panel angle to solve the problems existing in the above-mentioned technologies.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0022] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," and "connect" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0023] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0024] Example like Figure 1-11As shown, the present invention discloses a photovoltaic direct-drive energy storage outdoor advertising lightbox, comprising a lightbox body 1, a support assembly 2, and a photovoltaic module 3. The lightbox body 1 is mounted on the ground via the support assembly 2, the photovoltaic module 3 is mounted on the back of the lightbox body 1 via a first adjustment mechanism 4, and the support assembly 2 is connected to the lightbox body 1 via a second adjustment mechanism 5.

[0025] The main body 1 of the lightbox includes a profile base 11, a profile cover 12, a skinning plate 13, a reflective film 14, and a light guide plate 15. One side of the profile cover 12 is engaged with and rotatably connected to one side of the profile base 11. The profile cover 12 is also equipped with a rotary latch 121 to facilitate the opening and closing of the lightbox and to facilitate internal maintenance and picture replacement.

[0026] The other three sides of the profile base 11 are provided with waterproof adhesive strips 16. When the profile cover 12 is placed on the profile base 11, the other three sides, except for the rotating side, are elastically pressed and sealed by the waterproof adhesive strips 16, reducing the seepage of rainwater from the side wall joints of the light box, thereby protecting the internal components.

[0027] The profile base 11 also has a fixing frame 17 inside, and the skinning plate 13, reflective film 14, and light guide plate 15 are arranged sequentially from the inside to the outside inside the fixing frame 17. A transparent panel 18 is fixedly installed on the inner side of the profile cover 12, and a waterproof strip 19 is provided around the edge of the transparent panel 18, which is located between the transparent panel 18 and the profile cover 12. The waterproof strip 19 can form a second sealing barrier to prevent rainwater from seeping in from the gap between the profile cover 12 and the transparent panel 18.

[0028] A transparent heat-shrink tubing 110 is provided around the perimeter of the reflective film 14. An LED light strip 111 is provided around the perimeter of the light guide plate 15. The transparent heat-shrink tubing 110 is used to protect the edges of the reflective film 14, preventing it from curling or breaking and ensuring the reflective effect. The LED light strip 111 serves as a light source, and its light is evenly guided towards the transparent panel 18 through the refraction of the light guide plate 15 and the reflection of the reflective film 14, thereby achieving the lighting effect.

[0029] A picture 112 is also provided on the outer side of the mounting bracket 17. A ring of N-pole magnetic rubber strips 113 is provided around the perimeter of the mounting bracket 17, and a ring of S-pole magnetic rubber strips 114 is provided around the outer perimeter of the picture 112. The picture 112 is mounted on the mounting bracket 17 through the magnetic attraction between the N-pole and S-pole magnetic strips 113 and 114. The magnetic attraction between the N and S poles ensures that the picture 112 adheres tightly to the mounting bracket 17. When the advertising image needs to be changed, simply overcome the magnetic attraction to remove the old picture, and then align the S-pole magnetic strip 114 of the new picture with the N-pole magnetic strip 113 on the mounting bracket 17 to complete the fixing. No disassembly of the lightbox body 1 or use of tools is required, making the operation convenient.

[0030] The support assembly 2 includes a support panel 21, a counterweight 22, and support rods 23. The counterweight 22 is located at the bottom of the support panel 21 to lower the center of gravity of the entire lightbox, enhance its wind resistance, and prevent tipping. Anti-slip pads 25 are provided at the four corners of the bottom of the counterweight 22. Two support rods 23 are fixedly mounted above the support panel 21, with their top ends connected to the main body 1 of the lightbox. A storage battery 24 is also located above the support panel 21. The storage battery 24 stores the electrical energy converted by the photovoltaic module 3 and powers the LED light strip 111.

[0031] The second adjustment mechanism 5 is located between the support rod 23 and the light box body 1, and is used to adjust the pitch angle of the light box body 1. The second adjustment mechanism 5 includes a screw 51, a snap-fit ​​connector 52, a snap-fit ​​block 53, and a rotating shaft 54. The rotating shaft 54 ​​is located inside the snap-fit ​​connector 52. Each snap-fit ​​block 53 has a through hole for the screw 51 to pass through. The outer periphery of the snap-fit ​​connector 52 has a slot 55. The rotating shaft 54 ​​has a threaded hole that is threaded to engage with the screw 51. The snap-fit ​​connector 52 and the snap-fit ​​block 53 are snap-fitted together, and the snap-fit ​​connector 52 and the snap-fit ​​block 53 are fixedly connected by the screw 51 and the rotating shaft 54. Plugs 56 are provided at both ends of the snap-fit ​​connector 52 and the snap-fit ​​block 53.

[0032] During installation or adjustment, the snap-fit ​​connector 52 and snap-fit ​​block 53 can be pre-positioned by snapping them together. Then, the screw 51 is passed through the through hole on the snap-fit ​​block 53 and the slot 55 of the snap-fit ​​connector 52, and screwed into the threaded hole of the rotating shaft 54. As the screw 51 is tightened, the snap-fit ​​connector 52 and snap-fit ​​block 53 are pulled and fixed, thereby fixing the angle between the light box body 1 and the support rod 23. When the angle needs to be adjusted, loosen the screw 51, readjust the relative position of the snap-fit ​​connector 52 and snap-fit ​​block 53, and then tighten it again. The plug 56 is used to seal both ends of the snap-fit ​​connector 52 and snap-fit ​​block 53 to prevent dust and debris from entering the interior and to ensure the cleanliness and flexibility of the adjustment mechanism.

[0033] The first adjustment mechanism 4 includes a fixed plate 41, an adjustment plate 42, a connecting rod assembly 43, and locking components 44 disposed at both ends of the fixed plate. The fixed plate 41 is fixedly connected to the back of the profile base 11, and guide plates 45 are also disposed on both sides of the fixed plate 41. The adjustment plate 42 is connected to the fixed plate 41 through the connecting rod assembly 43. The connecting rod assembly 43 includes a first connecting rod 431, a second connecting rod 432, and a third connecting rod 433 symmetrically disposed at both ends of the fixed plate 41. A first connecting hole 421 and a second connecting hole 422 are provided on both sides of the adjustment plate 42, and a third connecting hole 451 and a guide groove 452 are provided on the guide plate 45.

[0034] One end of the first connecting rod 431 is hinged to the first connecting hole 421, and the other end is provided with a guide post 434, which is slidably connected to the guide groove 452. One end of the second connecting rod 432 is hinged to the third connecting hole 451, and the other end is hinged to one end of the third connecting rod 433, the other end of which is hinged to the second connecting hole 422. The first connecting rod 431 and the second connecting rod 432 are rotatably connected in the middle. By sliding the guide post 434 at the end of the first connecting rod 431 along the guide groove 452, and coordinating with the linkage of the second connecting rod 432 and the third connecting rod 433, the adjusting plate 42 is flipped relative to the fixed plate 41, thereby realizing the angle adjustment of the photovoltaic module 3.

[0035] The locking assembly 44 is fixed to the two side walls of the profile base 11 via mounting base 441. The locking assembly 44 includes a housing 442, a ratchet 443, two locking blocks 444, and a reversing wedge 445. A drive shaft 446 is provided on one side of the ratchet 443, and the drive shaft 446 is rotatably connected to the side wall of the housing 442. A boss 435 is provided on the outer side of the second link 432 near the fixed plate 41, and the end of the drive shaft 446 passing through the side wall of the housing 442 is coaxially fixedly connected to the boss 435. When the second link 432 rotates, the boss 435 drives the drive shaft 446 and the ratchet 443 to rotate synchronously, thereby associating the movement of the linkage mechanism with the state of the locking assembly 44.

[0036] Two locking blocks 444 are hinged inside the housing 442 and located on both sides below the ratchet 443. A compression spring 447 is fitted between each locking block 444 and the housing 442, and the compression spring 447 is used to elastically press the toothed end of the locking block 444 onto the outer ratchet tooth of the ratchet 443. A reversing wedge 445 is located directly below the ratchet 443 and between the two locking blocks 444. The reversing wedge 445 is rotatably connected to the housing 442 via a connecting shaft 448. A swing element 449 is provided at one end of the connecting shaft 448 extending out of the housing 442. The reversing wedge 445 has inclined abutment surfaces on its left and right sides. The swing element 449 is a manual lever.

[0037] By operating the manual lever, the reversing wedge 445 swings left and right, causing its inclined contact surface to shift to one side, pushing open the locking block 444 on that side. This disengages the teeth of the locking block 444 from the ratchet 443, while the locking block 444 on the other side remains engaged with the ratchet 443 under the action of the compression spring 447. This changes the unidirectional locking direction of the ratchet 443. When the reversing wedge 445 is in the middle position, both sides simultaneously push the locking blocks 444 outwards, disengaging both locking blocks 444 from the ratchet 443 and completely unlocking the adjusting plate 42. At this point, the angle of the photovoltaic module can be freely adjusted.

[0038] The photovoltaic module 3 includes a solar panel 31 and a mounting frame 32. The solar panel 31 is embedded in the mounting frame 32, and the mounting frame 32 is fixedly connected to the adjustment plate 42 by bolts. The power output terminal of the solar panel 31 is electrically connected to the charging terminal of the battery 24. The solar panel 31 generates direct current under sunlight and transmits the electrical energy to the battery 24 for storage through wires. The battery 24 is electrically connected to the LED light strip 111 through a power line. The power line passes through the interior of the support rod 23 and extends into the profile base 11, and is connected to the power supply terminal of the LED light strip 111.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
