Description

A multi-functional LED display screen Technical Field

[0001] This invention belongs to the field of LED display technology, and specifically relates to a multifunctional LED display. Background Technology

[0002] LED displays are screens that use light-emitting diodes (LEDs) as their display material. They are typically used to display text, images, and videos. LED displays can be divided into indoor and outdoor types. Indoor displays are mainly used in places such as shopping malls, stadiums, and conference rooms, while outdoor displays are commonly found in billboards, stadiums, and large event venues. LED displays have advantages such as high brightness, low power consumption, and long lifespan, and are therefore widely used in various scenarios.

[0003] LED displays are a very common type of display device, and different types of LED displays can be seen in various shopping malls, office buildings and other public areas. However, although there are many different types of LED displays on the market, most of them have relatively simple functions. They are usually fixed in one location for daily advertising or information display. With the increasing development of the advertising industry, various types of LED advertising displays can be seen everywhere. Traditional fixed LED displays are gradually failing to meet the basic requirements of advertising, namely attracting the attention of pedestrians. At the same time, most LED displays are currently single-sided structures and are usually installed against a wall. It is difficult for pedestrians from different directions and positions to fully observe the relevant display content, resulting in a very limited overall display effect. Summary of the Invention

A first connecting rod is fixedly connected to the outer wall of both the bottom and top drive shafts. A support rod is fixedly connected to the triangular support frame. A mounting base is fixedly connected to the top end of the support rod. A transmission bevel gear is rotatably connected to one side of the mounting base. A first driving bevel gear is fixedly installed on the outer wall of the middle drive shaft near the bottom end. A fixing sleeve is also sleeved on the outer wall of the middle drive shaft. A second connecting rod is fixedly connected to the outer wall of the fixing sleeve. A second driving bevel gear is fixedly connected to the bottom end of the outer wall of the second connecting rod.

[0013] Furthermore, both the bottom drive shaft and the middle drive shaft have spline grooves at their top centers, and both the middle drive shaft and the top drive shaft have positioning splines that can be inserted into the spline grooves at their bottoms. The outer wall of the fixing sleeve is also fixedly connected to a mounting plate, and the protective cover is fixed to the mounting plate with screws.

[0035] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0036] As shown in Figures 1-15, a multifunctional LED display screen of this embodiment includes a support part 1, which includes a triangular support frame 102. An upper support plate 104 and a lower support plate 105 are fixedly connected inside the triangular support frame 102. A bottom waterproof retaining ring 106 is fixedly connected to the top center of the triangular support frame 102, and a support base 101 is fixedly connected to the bottom of the triangular support frame 102. A removable front cover plate 103 is installed at the front end of the triangular support frame 102. The top of the triangular support frame 102 is located at the bottom waterproof retaining ring 106. The inner side of the 6 is also provided with a main wire hole 107, and the top corner of the triangular support frame 102 is also provided with a small wire hole to facilitate the wire harness of the protective lighting column 2 to pass through into the triangular support frame 102. The support part 1 mainly plays a supporting role. The triangular support frame 102 can provide stable support for the protective lighting column 2, the top cover 3 and the display screen rotation control mechanism 4 on its top. The bottom waterproof ring 106 at the top of the triangular support frame 102 can play a waterproof role and prevent rainwater from entering the interior of the triangular support frame 102.

[0037] As shown in Figures 7 and 8, protective lighting columns 2 are fixedly connected to the top corners of the support unit 1. The protective lighting columns 2 include multiple support columns 201 fixed to the top corners of the support unit 1. Positioning slots 202 are opened at adjacent positions on the outer side of the multiple support columns 201. An LED light assembly 203 is embedded in each positioning slot 202. The LED light assembly 203 has multiple evenly distributed LED light cores 204. The protective lighting columns 2 can provide a certain degree of safety protection and also have a night lighting function. By setting multiple support columns 201, a certain degree of protection can be provided for the rotating intelligent LED display screen 6 inside. The multiple support columns 201 can withstand a certain force of impact. At the same time, when the LED light assembly 203 embedded in each positioning slot 202 is powered on, its multiple LED light cores 204 will light up normally, thus providing a lighting function at night or in poor visibility conditions. The LED light assembly 203 can be controlled independently, and its on and off time can be controlled and adjusted by the background according to actual needs.

[0038] As shown in Figures 1-7, a top cover 3 is installed on the top of multiple protective lighting columns 2. The top cover 3 is used for top protection and rain protection.

[0039] As shown in Figures 5-14, a display screen rotation control mechanism 4 is installed on the support part 1. The display screen rotation control mechanism 4 includes a servo motor 401 mounted on the upper support plate 104. The top end of the output shaft of the servo motor 401 is fixedly connected to a bottom drive shaft 402 that passes through the top of the upper support plate 104 and the top of the triangular support frame 102 via a coupling. A middle drive shaft 403 is inserted into the top end of the bottom drive shaft 402, and a top drive shaft 404 is inserted into the top end of the middle drive shaft 403. A first connecting rod 4 is fixedly connected to the outer wall of both the bottom drive shaft 402 and the top drive shaft 404. 05. A support rod 408 is fixedly connected to the triangular support frame 102. A mounting base 409 is fixedly connected to the top of the support rod 408. A transmission bevel gear 410 is rotatably connected to one side of the mounting base 409. A first drive bevel gear 411 is fixedly installed on the outer wall of the middle transmission shaft 403 near the bottom. A fixing sleeve 412 is also sleeved on the outer wall of the middle transmission shaft 403. A second connecting rod 413 is fixedly connected to the outer wall of the fixing sleeve 412. A second drive bevel gear 414 is fixedly connected to the bottom of the outer wall of the second connecting rod 413. The display screen rotation control mechanism 4 serves as the drive structure. This mechanism drives multiple sets of rotating intelligent LED displays 6 to reciprocate at a certain angle. Specifically, when the servo motor 401 is working, it can drive the bottom drive shaft 402, the middle drive shaft 403, and the top drive shaft 404 to rotate synchronously through its output shaft. When the output shaft of the servo motor 401 rotates clockwise, the first drive bevel gear 411 on the middle drive shaft 403 will rotate synchronously with it. Since the first drive bevel gear 411 meshes with the transmission bevel gear 410, and the transmission bevel gear 410 meshes with the second drive bevel gear 414, the first drive bevel gear 402 rotates clockwise. The moving bevel gear 411 can drive the second driving bevel gear 414 to move synchronously in the opposite direction through the transmission bevel gear 410. This allows the second driving bevel gear 414 to drive the fixed sleeve 412 and the second connecting rod 413 to rotate synchronously. The output shaft of the servo motor 401 will reciprocate within a rotation angle range of 0-120°. This can simultaneously drive multiple sets of rotating intelligent LED displays 6 to perform regular, staggered rotational movements, enabling the rotating intelligent LED displays 6 to maintain a state of motion and thus better attract the attention of pedestrians.

[0040] Furthermore, both the bottom drive shaft 402 and the middle drive shaft 403 have spline grooves 406 at their top centers. The bottom of both the middle drive shaft 403 and the top drive shaft 404 are fixedly connected with positioning splines 407 that can interlock with the spline grooves 406. The outer wall of the fixed sleeve 412 is also fixedly connected with a mounting plate 415. The protective cover 5 is fixed to the mounting plate 415 with screws. By interlocking the spline grooves 406 and the positioning splines 407, the bottom drive shaft 402, the middle drive shaft 403 and the top drive shaft 404 can be quickly connected and positioned to maintain coaxial movement. At the same time, it is also convenient to quickly disassemble and repair the equipment in case of failure.

[0041] In addition, the gear transmission part of the display screen rotation control mechanism 4 is equipped with a protective cover 5. The protective cover 5, which is fixed on the mounting plate 415, can provide external protection for the gear transmission structure between the first drive bevel gear 411, the transmission bevel gear 410 and the second drive bevel gear 414, so as to prevent the wire harness connecting multiple sets of rotating intelligent LED displays 6 from being caught between the gears during rotation.

[0042] As shown in Figures 9-14, three sets of rotating intelligent LED displays 6 are installed on the outside of the display rotation control mechanism 4. The rotating intelligent LED displays 6 are used for advertising and audio-visual displays. Each rotating intelligent LED display 6 includes a rotating frame 601 fixedly installed on the outside of the display rotation control mechanism 4. A circular hole 602 is provided at the center of the bottom of the rotating frame 601, and a top waterproof retaining ring 603 is provided at the center of the top of the rotating frame 601. Each outer wall of the rotating frame 601 has a display screen mounting slot 604, in which an intelligent display screen 605 is fitted. Each display screen mounting slot 604 has a wiring hole 606. The rotating intelligent LED displays 6 are used for normal advertising displays, and the intelligent display screens 605 are fitted into the display screen mounting slots 604. Furthermore, the periphery of both is coated with sealant, which provides a better seal when properly bonded, and also provides good dustproof, waterproof, and insect-proof protection. The data cable of the smart display screen 605 can pass through the split hole 606 into the interior of the rotating frame 601 and be plugged into the main line. In addition, since the rotating frame 601 has a round hole 602 at the bottom center and a top waterproof retaining ring 603 at the top center, when multiple sets of rotating smart LED displays 6 are vertically assembled, the top waterproof retaining ring 603 of the lower layer can be inserted into the round hole 602 of the upper layer, thereby achieving a good waterproof effect and effectively preventing rainwater from seeping into the interior through the assembly gaps between multiple sets of rotating smart LED displays 6. At the same time, this structure also provides dustproof and insect-proof protection.

[0043] Furthermore, when the multiple vertically distributed rotating intelligent LED displays 6 are in operation, each intelligent display 605 can display an advertisement image individually, or multiple displays in the same group can be connected for a single screen, or multiple intelligent displays 605 in the vertical direction can be connected for a single screen. This allows for the display of different advertising information according to actual needs. Moreover, because the multiple vertically distributed rotating intelligent LED displays 6 adopt a multi-faceted display structure design, the rotating intelligent LED displays 6 can display advertising information 360 degrees. When it is located in the middle of the space, it can facilitate pedestrians in different positions and directions to observe the advertising information, thereby achieving a better information display effect.

[0044] Furthermore, the three sets of rotating intelligent LED displays 6 are fixed to two first connecting rods 405 and one second connecting rod 413 respectively. Through the corresponding connection, the display rotation control mechanism 4 can drive the three sets of rotating intelligent LED displays 6 to perform staggered reverse rotation movements, so that the rotating intelligent LED displays 6 can better attract the attention of pedestrians, and at the same time make the rotating intelligent LED displays 6 have a better sense of technology and aesthetics.

[0045] As shown in Figure 15, the display screen rotation control mechanism 4 is also equipped with multiple wire harness binding mechanisms 7 corresponding to the rotating intelligent LED display screen 6. Each wire harness binding mechanism 7 includes a fixed bushing 701 sleeved on the display screen rotation control mechanism 4. A connecting plate 703 is fixedly connected to the outer side of the fixed bushing 701, and a wire harness holder 704 is fixedly connected to the other end of the connecting plate 703. Multiple fixed bushings 701 are fixed to the bottom drive shaft 402, the middle drive shaft 403, and the top drive shaft 404 by locking screws 702. The fixing mechanism allows for quick connection and easy disassembly. The wire harness binding mechanism 7 is mainly used for limiting and binding the main cable. By setting a connecting plate 703 between the fixed bushing 701 and the wire harness holder 704, the main cable can maintain a certain distance from the display screen rotation control mechanism 4. When the bottom drive shaft 402, the middle drive shaft 403 and the top drive shaft 404 rotate, they can also limit the main cable locked in the wire harness holder 704 to prevent the main cable from getting tangled during rotation.

[0046] As shown in Figures 5-7, a signal receiving unit 8 for receiving remote control signals and data is also installed inside the support part 1. The signal receiving unit 8 is mainly used to receive remote control signals and related data information from the background, so that the LED display screen can remotely control its working status and the advertising information displayed on the screen. At the same time, the signal receiving unit 8 is also connected to the power cable and the main cable for controlling the working status of the protective lighting column 2, the display screen rotation control mechanism 4, and the rotating intelligent LED display screen 6.

[0047] The working principle of this embodiment is as follows: a protective lighting column 2 is fixedly connected to the top corner of the support part 1. An LED light component 203 is embedded in each positioning slot 202. After being powered on, its multiple LED light cores 204 will light up normally, so that it can play a lighting function at night or in poor visibility conditions. The LED light component 203 can be controlled independently, and its opening and closing time can be controlled and adjusted by the background according to actual needs.

[0048] The support part 1 is equipped with a display screen rotation control mechanism 4, and three sets of rotating intelligent LED displays 6 are installed on the outside of the display screen rotation control mechanism 4. The three sets of rotating intelligent LED displays 6 are fixed to two first connecting rods 405 and one second connecting rod 413 respectively, so that the display screen rotation control mechanism 4 can drive the three sets of rotating intelligent LED displays 6 to perform staggered reverse rotation movements, so that the rotating intelligent LED displays 6 can better attract the eyes and attention of pedestrians, and at the same time make the rotating intelligent LED displays 6 have a better sense of technology and aesthetics.

[0049] When the multiple vertically distributed rotating intelligent LED displays 6 are in operation, each intelligent display 605 can display an advertising image individually, or multiple displays in the same group can be connected together, or multiple intelligent displays 605 in the vertical direction can be connected together. This allows different advertising information to be displayed according to actual needs. Furthermore, because the multiple vertically distributed rotating intelligent LED displays 6 adopt a multi-faceted display structure design, the rotating intelligent LED displays 6 can display advertising information 360 degrees. When it is located in the middle of the space, it can facilitate pedestrians in different positions and directions to observe the advertising information.

[0050] The display screen rotation control mechanism 4 is also equipped with multiple wire harness binding mechanisms 7 corresponding to the rotating intelligent LED display screen 6. By setting a connecting plate 703 between the fixed bushing 701 and the wire harness holder 704, the main cable can maintain a certain distance from the display screen rotation control mechanism 4. When the bottom drive shaft 402, the middle drive shaft 403 and the top drive shaft 404 rotate, they can also limit the main cable that is locked in the wire harness holder 704 to prevent the main cable from getting tangled during the rotation.

[0051] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
