Detailed Implementation

[0033] 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, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0034] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0035] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0036] In the description of this utility model, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product is usually placed during use, they are only for the convenience of describing this utility model 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, and therefore should not be construed as a limitation of this utility model.

[0037] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0038] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0039] In the existing technology, rotating display devices are mainly used indoors because they are not waterproof or have a simple waterproof design, resulting in poor waterproof performance. They cannot adapt to complex outdoor environments and have great limitations in use. When used outdoors, they are easily damaged by moisture, have a short service life, and have high maintenance costs.

[0040] In view of this, the designers have provided a waterproof light strip 005, which can improve the waterproof effect, adapt to complex environments such as outdoors, operate stably and for a long time in complex environments such as outdoors, with low failure rate and low maintenance cost.

[0041] Please refer to Figures 1-4 This embodiment provides a waterproof light strip 005, including a waterproof cover 100, a waterproof adhesive layer 200, a first circuit board 300, and LED beads 400; wherein:

[0042] The first circuit board 300 is fixed to the waterproof cover 100. The surface of the first circuit board 300 facing away from the waterproof cover 100 includes the LED mounting surface and the non-LED mounting surface. The LED LED 400 is mounted on the LED mounting surface. The waterproof adhesive layer 200 covers the surface of the first circuit board 300 near the waterproof cover 100, the four sides of the first circuit board 300, and the non-LED mounting surface.

[0043] As described above, the waterproof principle of the waterproof light strip 005 provided in this embodiment is as follows:

[0044] The waterproof adhesive layer 200 encases the first circuit board 300, forming a near-closed protective structure. This provides excellent waterproofing, reducing the risk of short circuits or other electrical malfunctions caused by moisture or direct water contact, thus extending the lifespan of the waterproof LED strip 005 and enabling it to operate stably for extended periods in complex outdoor environments. Simultaneously, the waterproof adhesive layer 200 does not obstruct the area on the first circuit board 300 where the LED beads 400 are mounted, ensuring a stable connection between the LED beads 400 and the first circuit board 300. This guarantees stable illumination from the LED beads 400, resulting in a stable image and improved display performance of the waterproof LED strip 005.

[0045] The following embodiments illustrate the details of the waterproof light strip 005 of this application by way of example.

[0046] Please refer to Figures 1-4 In this embodiment, optionally, the waterproof light strip 005 includes a waterproof cover 100, a waterproof adhesive layer 200, a first circuit board 300, LED beads 400, a first sealing ring 500, a first screw 600, a second screw 700, a third screw 800, and a fourth screw 900. The first circuit board 300 is fixed to the waterproof cover 100 by the first screw 600, and the LED beads 400 are integrated on the first circuit board 300 and the two are electrically connected. The waterproof adhesive layer 200 covers the area of ​​the first circuit board 300 excluding the area where the LED beads 400 are mounted. The first sealing ring 500 is mounted on the waterproof cover 100.

[0047] Optionally, the waterproof cover 100 includes a cover body 110, a first end 120, and a second end 130. The cover body 110 can be a strip plate, and a strip-shaped mounting groove 111 is provided on one surface of the cover body 110. The length of the mounting groove 111 is consistent with the length direction of the cover body 110. The mounting groove 111 has two opposite sidewalls in its groove width direction and a bottom wall connecting the two sidewalls. Each sidewall is provided with a supporting protrusion 112. The number of supporting protrusions 112 on each sidewall can be multiple. The multiple supporting protrusions 112 have the same height and are spaced apart in the length direction of the mounting groove 111. The first end 120 is fixed to one end of the mounting groove 111 by a second screw 700, and the first end 120 closes one end of the mounting groove 111. The second end 130 is fixed to the other end of the mounting groove 111 by a third screw 800, and the second end 130 closes the other end of the mounting groove 111.

[0048] Meanwhile, an electrical connection hole 121 is provided on the first end 120, and a first sealing ring 500 is installed on the first end 120 and arranged around the electrical connection hole 121, which can seal the surrounding area of ​​the electrical connection hole 121.

[0049] Optionally, the first circuit board 300 is a strip-shaped component. Multiple recesses 310 are provided on both sides of the first circuit board 300 in its width direction. The width of the first circuit board 300 is approximately equal to the width of the mounting groove 111. The first circuit board 300 is placed flat within the mounting groove 111, located between the first end 120 and the second end 130. One surface of the first circuit board 300 simultaneously contacts multiple supporting protrusions 112, which position the first circuit board 300. A gap exists between the first circuit board 300 and the bottom wall of the mounting groove 111 to form a potting space. The LED mounting surface of the first circuit board 300, used for mounting the LED beads 400, faces upwards, meaning the LED mounting surface faces away from the bottom wall of the mounting groove 111. The sides of the first circuit board 300 in its width direction can contact the side walls of the mounting groove 111, thereby stabilizing the first circuit board 300. Meanwhile, due to the design of the recess 310, after the first circuit board 300 is installed in the mounting groove 111, the potting space is connected to the recess 310. Through the potting process, the waterproof adhesive can fill the potting space and the recess 310, and reach the surface of the first circuit board 300 facing away from the mounting groove 111 from the recess 310, thereby covering the area of ​​the first circuit board 300 except for the lamp bead mounting surface, thus forming an integrated waterproof adhesive layer 200 with good sealing effect. It should be understood that due to the design of the first end 120 and the second end 130, when the adhesive is potted, it can fill the area between the first end 120 and the first circuit board 300, as well as between the second end 130 and the first circuit board 300, ultimately covering the entire four sides of the first circuit board 300.

[0050] Furthermore, when the first circuit board 300 is fixed to the housing body using the first screw 600, the first screw 600 penetrates the first circuit board 300 and is screwed into the threaded hole on the supporting protrusion 112. The supporting protrusion 112 not only supports the first circuit board 300 but also provides a mounting point for the first screw 600. In addition, to improve the connection strength, the first circuit board 300 is also fixedly connected to the first end 120 by a fourth screw 900. The electrical connection pins on the first circuit board 300 can penetrate the waterproof adhesive layer 200 and pass through the electrical connection hole 121, thereby facilitating electrical connection with other electronic components such as the second circuit board 004. Since the electrical connection hole 121 is sealed around by the first sealing ring 500, the waterproof performance of the electrical connection pins is improved.

[0051] It should be noted that there can be multiple LED beads 400 on the first circuit board 300, and the multiple LED beads 400 are evenly spaced along the length of the first circuit board 300.

[0052] Furthermore, depending on the requirements, the waterproof light strip 005 may include multiple first circuit boards 300, with the ends of the multiple first circuit boards 300 joined together to increase the length of the waterproof light strip 005. For example, the overall length of the waterproof light strip 005 is not less than 2m. Adjacent first circuit boards 300 can be electrically connected via conductive sheets or power lines to facilitate signal and power transmission. Simultaneously, all first circuit boards 300 can be fixed to the protective cover body 110 with screws.

[0053] The waterproof light strip 005 provided in this embodiment has good waterproof performance, can adapt to complex outdoor environments, is not easily damaged by moisture, is safe to use, and has a long service life.

[0054] Please combine Figures 5-8 This embodiment also provides a waterproof rotating display mechanism, which includes:

[0055] The system comprises a waterproof housing 001, a drive unit 002, a support unit 003, a second circuit board 004, multiple waterproof light strips 005, a waterproof plate 006, a second sealing ring 007, and a display light panel 008. The drive unit 002 is mounted on the waterproof housing 001 and is connected to the support unit 003, driving the support unit 003 to rotate. The second circuit board 004 is installed between the support unit 003 and the waterproof plate 006, with the second sealing ring 007 sandwiched between them. The second circuit board 004 is located within the area enclosed by the second sealing ring 007. The display light panel 008 is mounted on the side of the waterproof plate 006 opposite to the second circuit board 004, and the display light panel 008 and the waterproof plate 006 are covered by waterproof adhesive. Waterproof covers 100 for the multiple waterproof light strips 005 are all mounted on the support unit 003, and the multiple waterproof light strips 005 are arranged radially around the display light panel 008. Furthermore, the power-connecting pins on the first circuit board 300 of each waterproof light strip 005 pass through the waterproof plate 006 and are electrically connected to the second circuit board 004.

[0056] With this design, after the drive component 002 is activated, it can drive the support component 003 to rotate, thereby driving the display light panel 008 and multiple waterproof light strips 005 to rotate together. The LED beads 400 on the display light panel 008 and multiple waterproof light strips 005 light up to display images.

[0057] It is worth noting that the display light panel 008 is a circuit board on which multiple LED beads 400 are mounted. The display light panel 008 is roughly circular and fills the area where no image is displayed between multiple waterproof light strips 005.

[0058] Optionally, the waterproof plate 006 is provided with multiple clearance holes 061, the number of which is equal to the number of waterproof light strips 005 and they correspond one-to-one. When the waterproof cover 100 of the waterproof light strip 005 is installed on the support 003, the first end 120 of each waterproof light strip 005 can be inserted into the corresponding clearance hole 061, and the first sealing ring 500 is clamped by the waterproof plate 006 and the first end 120, improving the sealing performance of the clearance hole 061. The power connection pins on the first circuit board 300 can pass through the power connection hole 121 and the clearance hole 061 and be electrically connected to the power connection pins on the second circuit board 004. The connection position of each waterproof light strip 005 to the waterproof plate 006 is sealed by the corresponding first sealing ring 500, resulting in good sealing performance and waterproof effect at the connection position of each waterproof light strip 005.

[0059] Optionally, the drive component 002 includes a motor 021, a support base 022, and a drive shaft 023. The motor 021 is mounted on the waterproof housing 001 and connected to the drive shaft 023. The support base 022 is mounted on the waterproof housing 001 and spaced apart from the motor 021. The drive shaft 023 and the support base 022 are rotatably connected via bearings. The drive shaft 023 is drively connected to the support component 003. That is, after the motor 021 starts, it can drive the support component 003 to rotate via the drive shaft 023.

[0060] Furthermore, the drive shaft 023 is provided with a first through hole 024 for the power cable to pass through; the support member 003 is provided with a second through hole 031 for the power cable to pass through, and the second through hole 031 is coaxially arranged with the second sealing ring 007. One end of the drive shaft 023 can be inserted into the support member 003, and the two are tightly connected. The first through hole 024 and the second through hole 031 are connected, facilitating sealing. To improve sealing, sealant can be applied between the insertion point of the drive shaft 023 and the support member 003. During assembly, one end of the power cable can pass through the first through hole 024 and the second through hole 031, and then be electrically connected to the second circuit board 004. The other end of the power cable can be provided with a waterproof plug 091. After the power cable is laid out, sealant can be injected at the connection point of the first through hole 024 and the second through hole 031 to improve waterproof performance.

[0061] It should be understood that, to prevent the power cord from twisting and tangling, a slip ring 009 can be installed outside the drive shaft 023. Carbon brushes are mounted on the slip ring 009. The slip ring 009 is electrically connected to the second circuit board 004 via a first power cord passing through the first wire hole 024 and the second wire hole 031. The carbon brushes are connected to a second power cord, the end of which can be connected to a waterproof plug 091. When the waterproof plug 091 is engaged with the power supply, power can be transmitted to the second circuit board 004 through the carbon brushes and the slip ring 009, thereby supplying power to the first circuit board 300 and the indicator light board 008, etc.

[0062] The waterproof rotating display mechanism provided in this embodiment has good waterproof performance, can adapt to complex outdoor environments, can operate stably and reliably for a long time, has a low failure rate, and low maintenance costs.
