Description

Technical Field

[0001] This utility model relates to the field of lighting device technology, and in particular to an electric folding LED lamp with audible and visual alarm. Background Technology

[0002] LED lighting fixtures are widely used in emergency rescue, outdoor operations, and other scenarios due to their advantages such as energy saving, long lifespan, and high brightness. In these scenarios, the lighting fixtures need to have multi-directional lighting capabilities (adjustable angles or foldable storage to adapt to different spaces) as well as alarm and loudspeaker warning functions to ensure operational safety.

[0003] Existing LED lighting fixtures with folding capabilities have the following drawbacks:

[0004] Complex structure and control: Most folding lights use multi-motor drive or complex electronic control systems to achieve folding, resulting in high product costs, high failure rates, and the need for professional operation, making them unsuitable for rapid deployment in emergency scenarios;

[0005] Limited functionality: Existing folding lights only focus on lighting and folding functions, without integrating sound and light alarm components. In rescue scenarios, additional alarm devices need to be carried, increasing the burden and cost of carrying them.

[0006] Weight and cost issues: Some products use heavy metal materials or redundant structures, which are heavy, have poor portability, and are difficult to manufacture, further increasing costs.

[0007] In summary, existing technologies lack a simple, low-cost, lightweight, and integrated audible and visual alarm-equipped electric folding LED light fixture, which cannot meet the comprehensive needs of emergency rescue and other scenarios. Utility Model Content

[0008] The purpose of this invention is to provide an electric folding LED lamp with audible and visual alarms to solve the problems of existing folding LED lamps, such as complex structure, high cost, and limited functionality.

[0009] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0010] An electrically operated folding LED light fixture with audible and visual alarm, comprising:

[0011] LED lamp body, the LED lamp body being used to provide lighting;

[0012] A folding drive assembly includes an electric push rod, a fixed shaft, a drive linkage, a rocker arm, and a fixing lug; the fixed shaft internally houses the electric push rod, a sliding base, and a flange inner tube; wherein...

[0013] One end of the electric push rod is fitted inside the inner tube of the flange and connected to one end of the inner tube; the other end of the inner tube of the flange is connected to the slip ring, and the slip ring is connected to the sliding base.

[0014] The hinge of the sliding base is hinged to one end of the active connecting rod, and the other end of the active connecting rod is hinged to the rocker arm; the rocker arm is connected to the LED lamp body; the fixed ear is used to support the rocker arm to rotate around it, so as to realize the folding or unfolding of the LED lamp body.

[0015] An audible and visual alarm component is installed inside the housing assembly of the lamp and is used for audible and visual alarm functions.

[0016] Furthermore, the folding drive assembly also includes an electric push rod fixing nut, a cover fixing bolt, and an inner tube fixing ring; the electric push rod fixing nut is used to fix one end of the electric push rod to the cover assembly, the inner tube fixing ring is fixed to one end of the fixed shaft, and the cover fixing bolt is used to fix the inner tube fixing ring to the cover assembly.

[0017] Furthermore, the housing assembly includes an upper housing and a lower housing; the upper housing and the lower housing are connected by bolts, and a decorative strip is provided between the upper housing and the lower housing.

[0018] Furthermore, the audible and visual alarm component includes a warning light and a loudspeaker. The warning light is a red and blue dual-color warning light used to provide visual alarm signals; the loudspeaker is a programmable loudspeaker that can store and play various alarm voices.

[0019] Furthermore, the LED lamp body is made of extruded aluminum profile; the sliding base, active connecting rod, and rocker arm in the folding drive assembly are all made of die-cast aluminum alloy.

[0020] Furthermore, it also includes a lower fixing flange and an inner tube fixing ring sleeved on the outside of the fixing shaft; the lower fixing flange is connected to the inner tube fixing ring, and the fixing lug is fixed to the lower fixing flange by bolts; the inner tube fixing ring is fixed to the fixing shaft by bolts.

[0021] Furthermore, the number of LED lamp bodies is no less than two, and each LED lamp body is hinged to an independent rocker arm and an active connecting rod to achieve synchronous folding or unfolding.

[0022] Furthermore, the folding drive assembly also includes an inner tube spacer, which is fixed inside the port of the fixed shaft by bolts and is used to slide and limit the inner tube of the flange.

[0023] The beneficial effects achieved by this utility model are:

[0024] 1. Compared to existing multi-motor folding and functionally separate lamps, this utility model integrates the electric push rod for folding drive and the inner tube of the flange inside the fixed shaft. This avoids the bulk redundancy caused by the external power components and messy pipelines of traditional folding lamps, improving the overall structural compactness and making it suitable for installations in confined spaces such as fire truck lifting masts and emergency tripods. On the other hand, the inner tube of the flange and the sliding base form a double support within the fixed shaft, which not only provides radial limit for the electric push rod to prevent it from shifting due to vibration during operation, but also provides precise guidance for the subsequent sliding of the sliding base within the fixed shaft, avoiding malfunctions caused by transmission path deviation. This solves the defects of existing folding lamps, such as loose structure and large space occupation, reduces structural complexity and production and maintenance costs, and also reduces the overall weight of the lamp, making it suitable for installation in confined spaces and for lightweight requirements.

[0025] 2. Compared with the floating folding structure without fixed ears, the fixed ears of this utility model can limit the rotation trajectory of the rocker arm, avoiding the LED lamp body from shifting or getting stuck during the folding process; at the same time, the hinged cooperation between the rocker arm and the fixed ears can distribute the weight load of the LED lamp body, avoid deformation caused by excessive force on a single link, and ensure that it can maintain a precise folding / unfolding position after long-term use, adapting to the angle requirements of multi-directional lighting.

[0026] 3. This utility model integrates the sound and light alarm component into the upper housing of the lamp. Compared with the existing separate solution of lighting fixture + external alarm device, this integrated structure eliminates the need to carry and install an independent alarm device, reducing the amount of equipment to carry in emergency scenarios. Furthermore, the alarm component shares power supply and mounting base with the lamp, eliminating the need for additional wiring and fixing, which can meet the core requirement of rapid response in emergency scenarios.

Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0039] The following is in conjunction with specific appendices Figures 1-6 The technical solution of this embodiment will be described in detail below.

[0040] like Figures 1-6As shown, this embodiment proposes an electrically folding LED lamp with audible and visual alarms, comprising:

[0041] An electrically operated folding LED light fixture with audible and visual alarm, comprising:

[0042] LED lamp body 18, LED lamp body 18 is used to provide lighting;

[0043] The folding drive assembly includes an electric push rod 6, a fixed shaft 9, a driving link 17, a rocker arm 16, and a fixing lug 15; the fixed shaft 9 internally houses the electric push rod 6, a sliding base 7, and a flange inner tube 11; wherein...

[0044] One end of the electric push rod 6 is fitted inside the flange inner tube 11 and connected to one end of the flange inner tube 11; the other end of the flange inner tube 11 is connected to the slip ring 10, and the slip ring 10 is connected to the sliding base 7.

[0045] The hinge 701 of the sliding base 7 is hinged to one end of the active link 17, and the other end of the active link 17 is hinged to the rocker arm 16; the rocker arm 16 is connected to the LED lamp body 18; the fixed ear 15 is used to support the rocker arm 16 to rotate around it, so as to realize the folding or unfolding of the LED lamp body 18.

[0046] The audible and visual alarm component is installed inside the housing of the lamp and is used for audible and visual alarm functions.

[0047] In this embodiment, the folding drive assembly further includes an electric push rod fixing nut 1, a cover fixing bolt 2, and an inner tube fixing ring 3; the electric push rod fixing nut 1 is used to fix one end of the electric push rod 6 to the cover assembly, the inner tube fixing ring 3 is fixed to one end of the fixing shaft 9, and the cover fixing bolt 2 is used to fix the inner tube fixing ring 3 to the cover assembly.

[0048] Specifically, the electric actuator fixing nut 1 can prevent the electric actuator 6 from shifting due to vibration during operation, ensuring accurate power transmission. The inner tube fixing ring 3 enhances the connection stability of the fixing shaft 9, forms a stable connection with the upper cover 21, improves the connection stability of the cover assembly, and ensures the rigidity of the overall structure of the lamp.

[0049] In this embodiment, the housing assembly includes an upper housing 21 and a lower housing 19; the upper housing 21 and the lower housing 19 are connected by bolts, and a decorative strip 20 is provided between the upper housing 21 and the lower housing 19. The decorative strip 20 is fitted into the joint between the two to fill the gap and also serves a decorative function.

[0050] Specifically, the housing assembly provides dust and water protection for all internal components, preventing outdoor rain and sand from intruding and causing electrical short circuits or mechanical corrosion. It also provides independent installation space for the audible and visual alarm components and the folding drive components, ensuring signal transmission from the alarm components (the upper housing has pre-reserved light-transmitting windows and sound amplification holes) while preventing interference from the drive components' movement. The decorative strip 20 enhances the sealing of the joints and the overall aesthetic integrity, achieving integrated protection and functional zoning, adapting to the complex environments of outdoor emergency rescue.

[0051] To address the issue that existing folding lamps only have lighting functions and require an additional independent alarm device, increasing the carrying burden, the sound and light alarm component in this embodiment includes a warning light 5 and a loudspeaker 4. The warning light 5 is a red and blue dual-color warning light used to provide visual alarm signals; the loudspeaker 4 is a programmable loudspeaker that can store and play various alarm voices.

[0052] Specifically, the warning light 5, loudspeaker 4, and electric actuator 6 can be electrically connected to an external controller and power supply via cables within conduit 14. The electric actuator 6 is driven by receiving control signals from the external controller, and audible and visual alarms are activated. The red and blue dual-color design of the warning light meets emergency rescue visual warning standards, and the high-volume characteristics of the loudspeaker ensure that the sound coverage meets the needs of on-site command.

[0053] In this embodiment, the LED lamp body 18 is made of extruded aluminum profile; the sliding base 7, active connecting rod 17, and rocker arm 16 in the folding drive assembly are all made of die-cast aluminum alloy.

[0054] The LED lamp body 18 utilizes the high thermal conductivity of extruded aluminum profiles to quickly dissipate the heat generated during LED operation, preventing light decay of the LED beads due to high temperatures, resulting in good heat dissipation and low cost. Meanwhile, the sliding base 7, active connecting rod 17, and rocker arm 16 are all made of aluminum alloy, making production convenient and inexpensive, thus reducing the overall production cost of the lamp.

[0055] In this embodiment, the electric folding LED lamp also includes a lower fixing flange 12 and an inner tube fixing ring 13 sleeved on the outside of the fixing shaft 9; the lower fixing flange 12 is connected to the inner tube fixing ring 13, and the fixing lug 15 is fixed to the lower fixing flange 12 by bolts; the inner tube fixing ring 13 is fixed to the fixing shaft 9 by bolts.

[0056] In this embodiment, the lower fixed flange 12 provides a stable mounting base for the fixed lug 15, ensuring the precise rotation trajectory of the rocker arm 16. Furthermore, the multi-point bolt connection to the mounting base enhances the overall wind and vibration resistance of the lighting fixture. The inner tube fixing ring 13 neatly positions the cables of the audible and visual alarm components and the electric push rod within the conduit 14 around the fixed shaft, preventing the cables from tangling or wearing out as they move with the folding drive component, thus balancing structural stability and pipeline safety.

[0057] In this embodiment, there are no fewer than two LED lamp bodies 18. Each LED lamp body 18 is hinged to the active connecting rod 17 via an independent rocker arm 16 to achieve synchronous folding or unfolding.

[0058] In one embodiment, such as Figure 4 As shown, the fixed shaft 9 has four sliding grooves. Correspondingly, in Figure 5 In the sliding base 7, there are four hinge parts 701, each hinge part 701 being hinged to an independent rocker arm 16 and an active connecting rod 17. When the sliding base 7 slides within the fixed shaft 9, the hinge parts 701 of the sliding base 7 can slide along the sliding groove. Correspondingly, there are four LED lamp bodies 18. Driven by the electric push rod 6, the sliding base 7 slides within the fixed shaft 9, and then the four LED lamp bodies 18 are simultaneously folded or unfolded by the independent rocker arms 16 and active connecting rods 17.

[0059] In this embodiment, the folding drive assembly also includes an inner tube spacer 8, which is fixed inside the port of the fixed shaft 9 by bolts and is used to slide and limit the flange inner tube 11.

[0060] Specifically, for the inner tube spacer 8, its lower end fits against the flange inner tube 11, forming a limit on the upper end of the flange inner tube 11, preventing the flange inner tube 11 from overtraveling when it extends with the electric push rod 6, thus achieving the transmission limit of the electric push rod 6.

[0061] Based on the content of the above embodiments, refer to Figure 6 The diagram illustrates the unfolding and folding process of the electrically folding LED lamp. The unfolding and folding process of the electrically folding LED lamp in this embodiment is as follows:

[0062] Unfolding process:

[0063] When the external power supply and controller are connected, the electric push rod 6 extends after receiving the drive signal from the controller. Because one end of the electric push rod 6 is rigidly fixed to the lower cover 19 through the electric push rod fixing nut 1, the power output is stable and pushes the flange inner tube 11 to slide upward along the inner axis of the fixed shaft 9. The nested fit between the flange inner tube 11 and the fixed shaft 9 limits its movement to only a linear trajectory and there is no radial offset. Since the upper end of the flange inner tube 11 is fixed to the slip ring 10, it synchronously drives the slip ring 10 to move upward along the outside of the fixed shaft. The slip ring 10 then pulls the sliding base 7 to move smoothly along the preset sliding groove of the fixed shaft 9. The hinge part 701 of the sliding base 7 moves with the base and pulls the active connecting rod 17 that is hinged to it. The active connecting rod 17 converts the linear motion of the sliding base 7 into the rotational motion of the rocker arm 16. The middle part of the rocker arm is hinged to the active connecting rod, and the other end rotates around the fixed ear 15. The fixed ear 15 is fixed to the lower fixed flange 12 by bolts. The position is stable, ensuring that the rotation trajectory of the rocker arm is accurate. Finally, it drives the LED lamp body 18 at the end of the rocker arm to unfold outward until it reaches the preset lighting angle (such as an angle of 120° with the cover). The electric push rod 6 stops moving after receiving the limit signal from the controller.

[0064] During this process, the inner tube spacer 8, which is fixed to the port of the fixed shaft 9, always limits the upper end of the flange inner tube 11 to prevent the flange inner tube 11 from sliding too far and causing the components to collide; the conduit 14 fixed by the inner tube fixing ring 13 remains neat as the lamp is unfolded to ensure that there is no cable tangling or pulling.

[0065] Folding process:

[0066] Reverse start-up: The controller sends a folding signal, the electric push rod 6 retracts, pulling the inner flange tube 11 to slide downwards along the fixed shaft 9. Due to the fixing effect of the electric push rod fixing nut 1, the retraction force is stably transmitted. The inner flange tube 11 drives the slip ring 10 and sliding base 7 to move downwards synchronously. The hinge part 701 of the sliding base pushes the active connecting rod 17, which converts the linear downward thrust into the inward rotational force of the rocker arm 16, causing the rocker arm 16 to rotate inwards around the fixed ear 15, folding and storing the LED lamp body 18. The electric push rod 6 stops after retracting to its shortest stroke. During this process, the sliding cooperation between the slip ring 10 and the fixed shaft 9 maintains smooth transmission without jamming or deviation.

[0067] The electrically folding LED lamp of this embodiment has the following technical advantages:

[0068] 1. Replacing multi-motor drive with "electric push rod + single transmission chain", and with the nested guide of fixed shaft-flange inner tube, folding / unfolding can be completed with simple operation without complex electrical control;

[0069] 2. The audible and visual alarm components are integrated into the housing and share the same system as the lighting, eliminating the need for additional alarm equipment;

[0070] 3. The LED light body, connecting rod, etc. are made of lightweight aluminum alloy, and the cover is made of engineering plastic, making the overall weight light and suitable for load-sensitive scenarios such as lifting masts;

[0071] 4. By reinforcing components such as the electric push rod fixing nut, inner tube fixing ring, and lower fixing flange, and combining this with the neatness of the inner tube fixing ring's pipeline, the structural stability is improved and the failure rate is reduced.

[0072] The sequence numbers of the embodiments in this application are for descriptive purposes only and do not represent the superiority or inferiority of the embodiments. The above are merely preferred embodiments of this application and do not limit the patent scope of this application.
