Description

Technical Field

[0001] This utility model relates to the field of LED lamp bead module technology, specifically an adjustable LED lamp bead module. Background Technology

[0002] As the name suggests, an LED lamp bead module is a component made by surface-mounting LED lamp beads on a PCB and then soldering wires onto them. An LED lamp bead module is one type of LED module. Due to its advantages over other types of modules, such as a wide beam angle, high brightness, and low light decay, it is widely used in advertising signs, illuminated signs, light boxes, 3D illuminated letters, vacuum-formed letters, and other advertising lighting; indoor and outdoor lighting for hotels, KTVs, shopping malls, and entertainment venues; landscape design; stage decoration; and urban lighting projects.

[0003] A search revealed that in a patent publication number CN221943801U, an adjustable display angle LED module is proposed that "this utility model uses a base, a sliding plate, a support plate, a fixing frame, and a lead screw. First, the first turntable is rotated, causing the first turntable to drive the lead screw to rotate and connect with the sliding plate by threads. At the same time, the sliding plate slides laterally inside the sliding groove. The support plate supports and limits the fixing frame, thereby adjusting the placement angle of the first display module and the base, improving the convenience of adjusting the placement angle of the first display module, improving the implementation of the display module in different installation environments, and thus improving the ease of use of the LED display module."

[0004] However, the above solution still has some shortcomings in actual use. The technical solution does not set a locking measure for the module after the angle is adjusted. The LED module cannot stay at the predetermined angle, which leads to a decrease in stability and reliability during use, and thus affects the overall user experience. Utility Model Content

[0005] This invention provides an adjustable LED lamp bead module to solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable LED lamp bead module, including a placement platform, the top of which is provided with an angle adjustment mechanism and a locking structure, the movable ends of which are connected to the bottom end of the LED module structure;

[0007] The angle adjustment mechanism includes an electric telescopic rod and a connecting plate. The bottom end of the electric telescopic rod is fixedly connected to the top end of the placement platform. A lifting block is fixedly installed on the movable end of the electric telescopic rod. Two sliding rods are fixedly installed on the side end of the lifting block. A sliding groove is opened inside the connecting plate. The sliding rods are located inside the sliding groove and connected to the inner wall of the sliding groove.

[0008] The locking structure includes a column, a hinge plate fixedly connected to the movable end of the column, the other end of the hinge plate fixedly connected to the bottom end of the LED module structure, a ratchet fixedly installed on the movable end of the column, the ratchet extending to the outside of the column, an abutment hook and a locking pin hinged to the outside of the column, the lowest point of the abutment hook overlapping the outside of the ratchet, and the bottom end of the locking pin engaging with the top end of the abutment hook.

[0009] Furthermore, the LED module structure includes a protective cover, a mounting plate is movably inserted into the back of the protective cover, and the module body is movably mounted inside the mounting plate.

[0010] Furthermore, the bottom of the protective cover is provided with a splicing groove, and the top of the connecting plate is equipped with a splicing strip, which is movably inserted into the splicing groove.

[0011] Furthermore, the initial state of the locking pin is perpendicular to the front of the column, and the maximum range of motion of the locking pin is perpendicular to the front of the column and in contact with the front of the column.

[0012] Furthermore, a cover is rotatably connected to the front of the column, and the ratchet, abutment hook, and locking pin are all located inside the cover.

[0013] Compared with the prior art, this utility model provides an adjustable LED lamp bead module, which has the following beneficial effects:

[0014] This adjustable LED module, through the setting of an angle adjustment mechanism and a locking structure, utilizes the movable end of an electric telescopic rod to drive two sliding rods along the sliding grooves opened inside the connecting plate via a lifting block. Combined with a locking pin and a stop hook, a ratchet limits the hovering angle of the hinge plate, enabling the LED module to achieve a self-locking function after angle deflection. This effectively solves the problem in existing technologies where LED modules cannot maintain stable hovering after angle adjustment. This self-locking mechanism ensures that the LED module maintains its set angle during use, thereby significantly improving the stability and reliability of the module in practical applications.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model discloses an adjustable LED lamp bead module, including a placement platform 1. The top of the placement platform 1 is provided with an angle adjustment mechanism 2 and a locking structure 4. The movable ends of the angle adjustment mechanism 2 and the locking structure 4 are connected to the bottom end of the LED module structure 3.

[0023] The angle adjustment mechanism 2 includes an electric telescopic rod 201 and a connecting plate 202. The bottom end of the electric telescopic rod 201 is fixedly connected to the top end of the placement platform 1. A lifting block 203 is fixedly installed on the movable end of the electric telescopic rod 201. Two sliding rods 204 are fixedly installed on the side end of the lifting block 203. A sliding groove 205 is opened inside the connecting plate 202. The sliding rods 204 are located inside the sliding groove 205 and connected to the inner wall of the sliding groove 205.

[0024] The LED module structure 3 includes a protective cover 301, a mounting plate 302 is movably inserted into the back of the protective cover 301, and a module body 303 is movably installed inside the mounting plate 302.

[0025] The locking structure 4 includes a column 401, with a hinge plate 402 fixedly connected to the movable end of the column 401. The other end of the hinge plate 402 is fixedly connected to the bottom end of the LED module structure 3. A ratchet 403 is fixedly installed on the movable end of the column 401. The ratchet 403 extends to the outside of the column 401. An abutment hook 404 and a locking pin 405 are hinged to the outside of the column 401. The lowest point of the abutment hook 404 overlaps with the outside of the ratchet 403. The bottom end of the locking pin 405 is movably engaged with the top end of the abutment hook 404.

[0026] Furthermore, to further improve the stability and reliability of the locking structure 4, an anti-slip texture or anti-slip protrusion can be provided on the surface of the locking pin 405 to increase the friction between the locking pin 405 and the abutment hook 404, preventing slippage or loosening during locking. Simultaneously, to ensure that the ratchet 403 can rotate smoothly and effectively engage with the abutment hook 404, an appropriate amount of lubricating oil can be applied to the rotating shaft of the ratchet 403 to reduce friction during rotation and improve the rotational efficiency and stability of the ratchet 403.

[0027] Specifically, the bottom end of the protective cover 301 is provided with a splicing groove 304, and the top end of the connecting plate 202 is equipped with a splicing strip 206, which is movably inserted into the splicing groove 304.

[0028] In this implementation scheme, the splicing strip 206 and splicing groove 304 enable the connecting plate 202 and the protective cover 301 to be quickly assembled or disassembled. This not only facilitates the user to adjust the angle of the LED module structure 3, but also facilitates later maintenance and replacement.

[0029] Furthermore, in order to increase the stability and smoothness of the LED module structure 3 when adjusting the angle, lubricating oil can be applied between the slide rod 204 and the inner wall of the slide groove 205 to reduce the friction between the two, so that the slide rod 204 can slide more smoothly inside the slide groove 205.

[0030] In addition, in order to precisely control the telescopic length of the electric telescopic pole 201 and thus achieve precise adjustment of the three angles of the LED module structure, a scale or electronic controller can be installed on the electric telescopic pole 201 so that users can intuitively understand the telescopic length of the electric telescopic pole 201 and make corresponding adjustments.

[0031] Specifically, the initial state of the locking pin 405 is perpendicular to the front of the column 401, and the maximum range of motion of the locking pin 405 is perpendicular to the front of the column 401 and in contact with the front of the column 401.

[0032] In this implementation scheme, the locking pin 405 allows the user to lock and unlock the LED module structure 3 at the hovering angle by operating the locking pin 405.

[0033] Specifically, a cover 406 is rotatably connected to the front of the column 401, and the ratchet 403, the abutment hook 404 and the locking pin 405 are all located inside the cover 406.

[0034] In this embodiment, the cover 406 not only effectively protects key components such as the ratchet 403, the abutment hook 404, and the locking pin 405 from external environmental interference and damage, such as dust and moisture, but also provides users with a more convenient operating space. Users can easily adjust and maintain the locking structure 4 by opening or closing the cover 406 without worrying about damaging the internal components. Furthermore, the rotating connection of the cover 406 ensures its stability and smoothness during opening or closing, providing users with a superior user experience.

[0035] When replacing the module body 303, the mounting plate 302 is pulled out from the protective cover 301, the new module body 303 is installed inside the mounting plate 302, and then the mounting plate 302 is inserted back into the back of the protective cover 301, completing the replacement of the module body 303. This process is simple and quick, requiring no disassembly of the entire LED module structure 3, greatly improving the efficiency of replacing the module body 303 and reducing the difficulty of operation.

[0036] When it is necessary to adjust the angle of the LED module structure 3, the user can first remove the locking pin 405 from the top of the abutment hook 404 so that the abutment hook 404 no longer overlaps with the outside of the ratchet 403.

[0037] At this point, the user can operate the electric telescopic rod 201, causing its movable end to slide the slide rod 204 inside the slide groove 205 via the lifting block 203, thereby driving the connecting plate 202 and the LED module structure 3 connected to it to adjust their angle. After the LED module structure 3 is adjusted to the required angle, the user then engages the locking pin 405 with the top of the abutment hook 404, so that the lowest point of the abutment hook 404 engages with the outer side of the ratchet 403, causing the ratchet 403 to be locked, thus locking the suspension angle of the LED module structure 3.

[0038] In summary, this adjustable LED module, by setting an angle adjustment mechanism 2 and a locking structure 4, allows the movable end of the electric telescopic rod 201 to drive two sliding rods 204 to slide along the sliding groove 205 inside the connecting plate 202 via the lifting block 203. Combined with the locking pin 405 and the abutment hook 404, the ratchet 403 limits the hovering angle of the hinge plate 402, enabling the LED module to achieve a self-locking function after angle deflection. This effectively solves the problem in existing technologies where LED modules cannot maintain stable hovering after angle adjustment. This self-locking mechanism ensures that the LED module maintains its set angle during use, thus significantly improving the stability and reliability of the module in practical applications.

[0039] It should be noted that the specific model and specifications of the electric telescopic rod 201 and the LED module structure 3 in the adjustable LED lamp bead module need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail.

[0040] Furthermore, the power supply and principle of the electric telescopic rod 201 and the LED module structure 3 in the adjustable LED lamp bead module are clear to those skilled in the art, and will not be described in detail here.

[0041] Furthermore, the working principle and wiring method of the electric telescopic rod 201 and LED module structure 3 in the adjustable LED lamp bead module are commonplace and belong to conventional methods or common knowledge. They will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
