Description

Technical Field

[0001] This invention relates to the field of LED lighting technology, and more particularly to a foldable, multi-directionally adjustable LED maintenance work light. Background Technology

[0002] LED work lights are widely used in automotive repair, equipment maintenance, outdoor operations, circuit board soldering, and pipeline inspection. When repairing an automotive engine compartment, it's often necessary to illuminate narrow gaps on the side of the engine; when inspecting electrical cabinets, it's necessary to illuminate deep wiring terminals from the side; and when inspecting the inner walls of pipes, it's necessary to project light onto the side of the pipe wall. Existing foldable or multi-directionally adjustable LED work lights typically use a hinge to connect the main lamp body and the auxiliary lamp body, allowing the lamp body to rotate or fold within a certain range. However, this type of structure generally has the following problems: when supplemental lighting is needed to the side of the main lamp body, the auxiliary lamp body is limited by the hinge arrangement and the interference of the support structure, allowing only a small angle of lateral rotation. It's difficult to flexibly move the illumination surface of the auxiliary lamp body to any angle on the side of the main lamp body and maintain stability. Especially when the main lamp body has its own support bracket or handle structure, the auxiliary lamp body is prone to colliding with these components during unfolding, resulting in limited side lighting range and failing to effectively eliminate blind spots on the side of the workpiece being inspected.

[0003] How to provide an LED maintenance work light that can flexibly supplement the light from the auxiliary lamp body to the side of the main lamp body at any angle and avoid structural interference is an urgent problem to be solved in this field. Summary of the Invention

[0004] This invention discloses a foldable, multi-directional adjustable LED maintenance work light, aiming to solve the technical problem of how to provide an LED maintenance work light that can flexibly supplement light from the auxiliary lamp body to the side of the main lamp body at any angle while avoiding structural interference.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A foldable, multi-directional adjustable LED maintenance work light includes a main board and a sub-board. A slot is formed through the inner wall of the top of the main board, and the sub-board is located within the slot. The light also includes: a shielding mechanism fixed to the outer periphery of the sub-board; an LED light panel one fixedly mounted on the front of the sub-board; an LED light panel three fixedly mounted on the back of the sub-board; an LED light panel two fixedly mounted on the back of the main board, with LED light panel one and LED light panel two having the same brightness, and LED light panel three having a lower brightness; a support mechanism for supporting the main board and sub-board; and a linkage mechanism installed on one side of the support mechanism. The support mechanism includes: two L-shaped brackets, symmetrically fixedly connected to the top outer wall of the main board, and each of their opposing outer walls is fixedly connected to a pivot two; a Y-shaped bracket one, the two L-shaped brackets are respectively damped and hinged to the Y-shaped bracket one through pivot two, and a handle is fixedly connected to the bottom end of the Y-shaped bracket one, the handle is equipped with a battery, and the battery is electrically connected to LED light board one, LED light board two and LED light board three; pivot one, fixedly connected to one side outer wall of the sub-board; side frame two, pivot one is damped and rotatably connected to one side inner wall of the side frame two, and pivot five is fixedly connected to both ends of the side frame two, the pivot five and pivot two are coaxially arranged; Y-shaped bracket two, the two pivot five are simultaneously damped and hinged to the inside of the Y-shaped bracket two, and the bottom end of the Y-shaped bracket two is damped and hinged to the side frame one through pivot four; pivot three, fixedly connected to one side outer wall of the side frame one, and pivot three is damped and rotatably connected to one side inner wall of the handle.

[0006] With its supporting mechanism, the sub-board achieves the following effects: Multi-directional and multi-angle adjustment, eliminating blind spots: Through multiple levels of damping hinges (hinge 1, 5, 4, 3, etc.) and a hinge structure, the sub-board can independently flip, sway laterally, and tilt up and down. Combined with the main board's own pitch adjustment, it can project light to sides, backs, or narrow gaps that are difficult to reach with traditional inspection lights, achieving true blind-spot-free illumination. Unique obstacle avoidance linkage structure for smooth operation: When the sub-board unfolds to the side, the hinge between the Y-shaped bracket 2 and the side bracket 1 raises it upwards first, effectively avoiding the L-shaped bracket and preventing mechanical interference. This linkage design requires no additional manual obstacle avoidance, allowing for seamless operation; the structure is compact and reliable. Dual-sided light panels with different brightness levels adapt to various scenarios: High-brightness and low-brightness light panels are installed on the front and back of the sub-board, respectively. After flipping and switching, it can be superimposed with the main board's high-brightness light panel for strong illumination, or the low-brightness side can be used alone for close-range inspections to prevent overexposure and glare. One board, two uses, eliminating the need to carry multiple lights. When assembled, the surface is flat and easy to store and carry: After the secondary board is inserted into the slot of the main board, the whole thing is a regular flat plate with no protruding hinges or brackets. Compared with traditional folding lamps, it is thinner and more regular in shape, making it easy to put into toolboxes or drawers, and less prone to being hooked or damaged.

[0007] In a preferred embodiment, the linkage mechanism includes: two protrusions 2, symmetrically fixedly connected to one side outer wall of the sub-plate; and protrusion 1, fixedly connected to one side outer wall of the main plate, with through holes 1 simultaneously provided on protrusion 1 and the two protrusions 2. The linkage mechanism further includes: a second through hole, which is disposed through the second and fifth rotating shafts; a first insert rod, which is movably inserted into the second through hole; and a second insert rod, which is movably inserted into the first through hole. The linkage mechanism further includes: a side plate, which is fixedly connected to one end of both the first and second insertion rods; and a spring, which is fixedly connected between the side plate and the first protrusion.

[0008] The linkage mechanism achieves the following effects: Eliminating multiple hinge gaps and improving assembly stability: The sub-plate connects to the main plate and handle via multiple damped hinges (pivots 1, 5, 4, and 3). Without locking, slight play at each hinge point in the assembled state can cause overall wobbling and a loose grip. The linkage mechanism simultaneously locks key moving parts with two insert rods, eliminating all hinge gaps and giving the assembled lamp the same rigidity as a one-piece lamp, significantly improving stability and feel. One insert, two locks, efficient operation: Insert rods 1 and 2 are linked via the same side plate, allowing for simultaneous locking or unlocking with a single push or pull. Compared to solutions requiring separate operation of multiple latches, this halves the steps and makes it more convenient to use.

[0009] In a preferred embodiment, the shielding mechanism includes: a U-shaped outer frame, fixedly connected to the outer periphery of the sub-plate; and a U-shaped inner frame, the top of which is fixedly connected to a snap-fit ​​edge, and the U-shaped inner frame is movably snapped into the U-shaped outer frame through the snap-fit ​​edge. The shielding mechanism further includes: a U-shaped baffle, the top of which is fixedly connected to a second snap-fit ​​edge, and the U-shaped baffle is movably snapped into the U-shaped inner sleeve frame through the second snap-fit ​​edge; and a handle, which is fixedly connected to the bottom end of the U-shaped baffle. The shielding mechanism further includes: multiple base plates, which are fixedly connected to the bottom end of the U-shaped baffle; and multiple magnetic sheets, which are respectively fixedly attached to the multiple base plates and the bottom end of the U-shaped outer frame, with two magnetic sheets at corresponding positions magnetically adsorbed. The stretching direction of the U-shaped baffle is consistent with the installation direction of the LED light panel three.

[0010] By incorporating a shielding mechanism, the following effects are achieved: Zoned lighting is realized, meeting the needs for comparative observation. The U-shaped baffle physically separates the light from the high-brightness and low-brightness areas, creating two distinct brightness zones on the work surface. Maintenance personnel can simultaneously observe the high-gloss details of the same workpiece, such as scratches and dust, and the low-gloss textures, such as paint smoothness and weld gloss, without needing to replace the lamp or adjust its position, thus improving maintenance efficiency. The multi-stage telescopic design facilitates storage and portability: The U-shaped outer frame, U-shaped inner frame, and U-shaped baffle form a three-stage sleeve structure. When not in use, it retracts completely around the outer perimeter of the sub-plate, without affecting the overall flat shape and thickness of the lamp, making it easy to store and carry. When in use, it can be pulled out, with an adjustable length to adapt to different shielding needs under various working conditions. Effective light mixing is achieved without needing to be close to the work surface: Unlike conventional shielding solutions, this shielding mechanism separates the light at the source, rather than relying on close proximity to the work surface to create shadows. Even when the lamp is far from the illuminated surface, the brightness difference between the high-brightness and low-brightness areas is maintained, with only a slight increase in the width of the intermediate transition zone. This design reduces the limitations of usage conditions and has a wider range of applications.

[0011] As described above, a foldable, multi-directional adjustable LED maintenance work light includes a main board and a sub-board. A slot is provided through the inner wall of the top of the main board, and the sub-board is located within the slot. The light also includes: a shielding mechanism fixed to the outer periphery of the sub-board; LED light panel one fixedly installed on the front of the sub-board; LED light panel three fixedly installed on the back of the sub-board; LED light panel two fixedly installed on the back of the main board, with LED light panel one and LED light panel two having the same brightness, and LED light panel three having a lower brightness; a support mechanism for supporting the main board and sub-board; and a linkage mechanism installed on one side of the support mechanism. The support mechanism includes: two L-shaped brackets symmetrically fixedly connected to the outer wall of the top of the main board, with rotating shafts two fixedly connected to their opposing outer walls; and Y-shaped brackets... The system comprises three side frames: a first frame, two L-shaped brackets respectively connected to a Y-shaped bracket via a second hinge with damping; a handle is fixedly connected to the bottom of the Y-shaped bracket, and a battery is installed inside the handle, electrically connected to LED light panels one, two, and three; a first hinge is fixedly connected to one side of the outer wall of the sub-plate; a second side frame is connected to one side of the inner wall of the second side frame with damping, and two ends of the second side frame are fixedly connected to a fifth hinge, which is coaxial with the second hinge; a second Y-shaped bracket has two fifth hinges simultaneously connected to the second Y-shaped bracket with damping, and the bottom of the second Y-shaped bracket is connected to the first side frame via a fourth hinge with damping; a third hinge is fixedly connected to one side of the outer wall of the first side frame, and is connected to one side of the inner wall of the handle with damping. This invention provides a foldable, multi-directional adjustable LED maintenance work light with multi-directional adjustment without dead angles, convenient assembly, and dual brightness.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] The foldable, multi-directional adjustable LED maintenance work light disclosed in this invention is mainly used in scenarios where LED lights are used.

[0020] Reference Figures 1-3 A foldable, multi-directional adjustable LED maintenance work light includes a main board 1 and a sub-board 3. A slot 10 is formed through the inner wall of the top of the main board 1, into which the sub-board 3 can be embedded. A shielding mechanism 2 is fixedly installed on the outer periphery of the sub-board 3. An LED light panel 4 is fixedly installed on the front of the sub-board 3, and an LED light panel 11 is fixedly installed on the back of the sub-board 3. An LED light panel 8 is fixedly installed on the back of the main board 1. The LED light panel 4 and LED light panel 8 have the same brightness, both being high-brightness; the LED light panel 11 has lower brightness and is used for close-range or anti-glare supplementary lighting.

[0021] The work light also includes a support mechanism 6 and a linkage mechanism 5. The support mechanism 6 supports the main board 1 and the sub-board 3, and the linkage mechanism 5 is installed on one side of the support mechanism 6.

[0022] The specific structure of the support mechanism 6 is as follows: Two L-shaped brackets 602 are symmetrically fixedly connected to the top outer wall of the main board 1. Two rotating shafts 603 are fixedly connected to the opposite outer walls of the two L-shaped brackets 602. The two L-shaped brackets 602 are dampedly hinged to a Y-shaped bracket 604 via the rotating shafts 603. A handle 605 is fixedly connected to the bottom end of the Y-shaped bracket 604. A battery 7 is installed inside the handle 605. The battery 7 is electrically connected to LED light board 4, LED light board 8, and LED light board 11, providing power to each light board.

[0023] A pivot 601 is fixedly connected to one outer wall of the sub-plate 3. A damped rotatable connection is made between one inner wall of the side frame 611 and the pivot 601, allowing the sub-plate 3 to rotate independently around the pivot 601. A pivot 610 is fixedly connected to each end of the side frame 611, and the pivot 610 is coaxial with the pivot 603. Both pivots 610 are simultaneously dampedly hinged within a Y-shaped bracket 609. The bottom end of the Y-shaped bracket 609 is dampedly hinged to the side frame 607 via a pivot 608. A pivot 606 is fixedly connected to one outer wall of the side frame 607, and the pivot 606 is dampedly rotatably connected to one inner wall of the handle 605.

[0024] Through the cooperation of the aforementioned support mechanism 6, main board 1, and sub-board 3, and by utilizing the linkage of multi-stage rotating shafts and hinge structures, the sub-board 3 can achieve various positional changes relative to the main board 1, thereby meeting lighting requirements at different angles.

[0025] Flipping and Reversing: Sub-plate 3 is connected to side frame 611 via a damped rotational connection through pivot 601, allowing it to rotate independently around the pivot and switch between the front and back sides. When high-brightness focused lighting is needed, LED light panel 4 (high brightness) faces down; when close-range anti-glare supplementary lighting is needed, sub-plate 3 is flipped so that LED light panel 11 (low brightness) faces down.

[0026] Lateral Deployment and Avoidance: When it is necessary to move the sub-board 3 to the side of the main board 1 for lateral supplementary lighting, firstly, using the damped hinge of pivot 608 between Y-shaped bracket 2 609 and side bracket 1 607, the sub-board 3 is lifted upwards at a certain angle, thereby avoiding the L-shaped bracket 602 on the main board 1 and preventing mechanical interference. Subsequently, through the rotation of pivot 5 610 within Y-shaped bracket 2 609, and the damped rotational connection between pivot 3 606 and handle 605, the side bracket 1 607, Y-shaped bracket 2 609, and sub-board 3 are swung to the side of the main board 1. Finally, combined with the independent flipping of pivot 1 601, the illumination surface of the sub-board 3 can be positioned at any angle on the side of the main board 1, achieving flexible and blind-spot-free lateral supplementary lighting.

[0027] Combined storage and expanded lighting: When lateral supplemental lighting is not needed, reverse the operation of the above mechanism to re-embed the secondary board 3 into the slot 10 of the main board 1. After merging, the LED light panel 3 11 on the back of the secondary board 3 and the LED light panel 2 8 on the back of the main board 1 face the same plane (e.g., both facing downwards). At this time, the entire lamp is flat, which is convenient for folding and storage; at the same time, the two light panels provide illumination, resulting in a wider illumination area and more uniform light.

[0028] Overall support and adjustment: The main board 1 is connected to the Y-type bracket 604 via an L-shaped bracket 602 and a second pivot 603 with damping, allowing for free adjustment of the tilt angle. The handle 605 can be used as a handheld part or as a suspension fulcrum, and the internal battery 7 provides power to all the light panels.

[0029] Reference Figure 4 In a preferred embodiment, the shielding mechanism 2 includes a U-shaped outer frame 201, a U-shaped inner frame 203, and a U-shaped baffle 205. The U-shaped outer frame 201 is fixedly connected to the outer periphery of the sub-plate 3. A snap-fit ​​edge 202 is fixedly connected to the top of the U-shaped inner frame 203, and the U-shaped inner frame 203 is movably snapped into the U-shaped outer frame 201 through the snap-fit ​​edge 202. A snap-fit ​​edge 204 is fixedly connected to the top of the U-shaped baffle 205, and the U-shaped baffle 205 is movably snapped into the U-shaped inner frame 203 through the snap-fit ​​edge 204. A handle 206 is fixedly connected to the bottom of the U-shaped baffle 205. In addition, a plurality of base plates 207 are fixedly connected to the bottom of the U-shaped baffle 205, and magnetic pieces 208 are fixedly attached to the base plates 207 and the bottom of the U-shaped outer frame 201, respectively, and the two magnetic pieces 208 at corresponding positions can be magnetically attracted. The stretching direction of the U-shaped baffle 205 is consistent with the installation direction of the LED light panel 311.

[0030] The blocking mechanism 2 is used to physically separate the light at the interface between the secondary plate 3 and the main plate 1 when the secondary plate 3 is joined and the secondary plate is flipped so that the LED light panel 3 11 on the back of the secondary plate and the LED light panel 2 8 on the back of the main plate face the same plane. The U-shaped outer sleeve 201, the U-shaped inner sleeve 203, and the U-shaped baffle 205 constitute a three-stage sleeve-type telescopic structure. When not in use, the U-shaped inner sleeve 203 and the U-shaped baffle 205 are completely retracted, without occupying extra space or affecting the flat shape of the entire lamp. When in use, the blocking depth can be extended by pulling down the U-shaped baffle 205 through the handle 206. When the U-shaped baffle 205 is pulled out to its maximum stroke, the magnetic piece 208 at the bottom of the U-shaped outer sleeve 201 and the magnetic piece 208 at the bottom of the U-shaped baffle 205 attract each other, keeping the unfolded state stable. When storing, push the U-shaped baffle 205 upwards, the magnetic sheet 208 will disengage from the adsorption, and the U-shaped baffle 205 will retract into the U-shaped inner frame 203 and the U-shaped outer frame 201 in sequence.

[0031] Regarding the light separation effect: Since the stretching direction of the U-shaped baffle 205 is consistent with the installation direction of LED light panel 3 11, the unfolded U-shaped baffle 205 is located below the junction between LED light panel 2 8 and LED light panel 3 11. When the two light panels illuminate downwards simultaneously, the U-shaped baffle 205 physically separates the two beams of light from near the light source, preventing the light from pre-mixing before leaving the lamp body. Because LED light panel 3 11 has lower brightness and LED light panel 2 8 has higher brightness, after being separated by the baffle, a clear brightness zone is formed on the working surface: the area below LED light panel 2 8 is the high-brightness area, and the area below LED light panel 3 11 is the low-brightness area. A clear brightness transition zone appears between the two due to the baffle, thus achieving a non-uniform lighting effect of "weak in the middle and bright on both sides".

[0032] Reference Figure 5 In a preferred embodiment, the linkage mechanism 5 includes a first protrusion 501, two second protrusions 503, a first through hole 502, a second through hole 504, a first insertion rod 505, a second insertion rod 508, a side plate 506, and a spring 507. The two second protrusions 503 are symmetrically fixedly connected to one side of the outer wall of the sub-plate 3. The first protrusion 501 is fixedly connected to one side of the outer wall of the main plate 1, and the first through hole 502 is simultaneously provided on both the first protrusion 501 and the two second protrusions 503. The second through hole 504 is provided inside the second pivot 603 and the fifth pivot 610. The first insertion rod 505 is movably inserted into the second through hole 504, and the second insertion rod 508 is movably inserted into the first through hole 502. The side plate 506 is simultaneously fixedly connected to one end of the first insertion rod 505 and the second insertion rod 508, and the spring 507 is fixedly connected between the side plate 506 and the first protrusion 501.

[0033] The linkage mechanism 5 is used to rigidly lock the movable parts such as the sub-plate 3, side bracket 2 611, pivot 2 603, and pivot 5 610 to the main board 1 when the sub-plate 3 is embedded in the slot 10 of the main board 1 and no lateral adjustment is required. This eliminates the degree of freedom caused by multiple damping hinge points and makes the whole lamp a stable whole.

[0034] When the sub-plate 3 is fully embedded in the slot 10 and all the rotating shafts are in their default combined position, the through hole 502 of protrusion 1 501 is aligned with the through holes 502 of the two protrusions 2 503, and the through hole 504 of rotating shaft 2 603 and rotating shaft 5 610 are also coaxially aligned. At this time, the insertion rod 2 508 is movably inserted into the through holes 502 of protrusion 1 501 and protrusion 2 503, locking the sub-plate 3 and the main plate 1 in the lateral direction to prevent the sub-plate 3 from coming out of the slot 10 or sliding relative to it. The insertion rod 1 505 is movably inserted into the through holes 504 of rotating shaft 2 603 and rotating shaft 5 610, locking the rotating shaft 2 603 on the Y-shaped bracket 1 604 side and the rotating shaft 5 610 on the side bracket 2 611 side, preventing them from rotating relative to each other.

[0035] One end of each of the two insertion rods, 505 and 508, is fixed to the same side plate 506. A spring 507 is fixed between the side plate 506 and the protrusion 501. In its natural state, the spring force of the spring 507 keeps the two insertion rods inserted into the holes, preventing accidental loosening. When unlocking is required (e.g., to switch to side lighting mode), the operator pulls the side plate 506 to overcome the spring force of the spring 507, causing the two insertion rods 505 and 508 to be pulled out of the holes simultaneously, thus releasing the lock.

[0036] When plug rod 1 (505) and plug rod 2 (508) are inserted simultaneously, the sub-plate 3, side bracket 2 (611), pivot 5 (610), pivot 2 (603), and main plate 1 are rigidly connected as a whole. The multiple degrees of freedom originally achieved through multiple damping hinges such as pivot 1 (601), pivot 4 (608), and pivot 3 (606) are all restricted, the lamp as a whole does not wobble, and the grip feels solid, no different from a regular fixed work lamp.

[0037] Working Principle: When using this work light, the entire light is lifted by the handle 605, and the battery 7 powers each light panel. During normal illumination, the secondary board 3 is embedded in the slot 10 of the main board 1. The LED light panel 2 8 on the back of the main board 1 and the LED light panel 3 11 on the back of the secondary board 3 illuminate in the same direction, forming a wide and uniform light. When side lighting is needed, first lift the secondary board 3 upwards via the pivot 4 608 to avoid the L-shaped bracket 602, then swing it to the side via the pivot 5 610 and the pivot 3 606, and independently flip the secondary board 3 using the pivot 1 601, so that the illumination surface of the secondary board 3 points to any angle to the side of the main board 1, achieving illumination without blind spots. When side lighting is not needed, reverse the operation to return the secondary board 3 to its original position, making the entire light flat for easy storage. Flipping the secondary board 3 via the pivot 1 601 allows switching between different brightness light panels on the front and back: LED light panel 4 (high brightness) is used for long-distance strong light, and LED light panel 3 11 (low brightness) is used for close-range anti-glare. After the shielding mechanism 2 is pulled out, it can separate the boundary light between LED light panel 2 8 and LED light panel 3 11, forming zoned lighting. The linkage mechanism 5 locks through the insertion rod 1 505 and insertion rod 2 508 the through hole 1 502 and through hole 2 504, eliminating the hinge gap and ensuring that the whole lamp is stable and does not wobble when assembled.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
