[0018] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0019] The embodiments of this utility model will be described below based on its overall structure.

[0020] Reference Figures 1-7As shown, this embodiment provides a lifting emergency light, including a frame 1. A positioning cylinder 2 is vertically positioned at the center of the frame 1. A lifting column assembly 3 is located inside the positioning cylinder 2. A motor drive device 4 is located at the bottom of the frame 1 to drive the lifting column assembly 3 to rise and fall. A lifting seat 5 is located at the top of the lifting column assembly 3. Multiple emergency lights 6 are mounted on the lifting seat 5. A flipping mechanism 7 is provided between the emergency lights 6 and the lifting seat 5. An automatic winding reel 8 connected to the wires of the emergency lights 6 is located on the frame 1. A battery pack 9 electrically connected to the emergency lights 6 and the motor drive device 4 is also located on the frame 1. In this lifting emergency light, a multi-stage lifting column assembly 3 hidden inside the positioning cylinder 2 is driven by a motor to lift the top lifting seat 5 and the emergency lights 6 to the required height. The flipping mechanism 7 adjusts the lamp head angle, and the automatic winding reel 8 ensures the orderly winding and unwinding of the wires during the lifting process. After receiving power, the motor drive unit 4 outputs torque to drive the lifting column assembly 3 to move linearly within the positioning cylinder 2, thereby achieving the vertical lifting of the lifting seat 5. The battery pack 9 provides an independent power supply for the entire system. The emergency light 6 provides illumination, and the flipping mechanism 7 changes the direction of the light. This provides an integrated emergency lighting solution that is height-adjustable, has an adjustable lighting angle, is self-powered, and is easy to move. It solves the problem of limited illumination range of fixed emergency lights, achieving flexible adjustment of lighting height and angle, greatly improving the coverage and applicability of emergency lighting. The automatic cord reel avoids cord tangling and damage, improving reliability.

[0021] Specifically, a protective shell 10 is provided around the frame 1, which surrounds the battery pack 9, the motor drive device 4, and the automatic winding reel 8. In this embodiment, a protective shell 10 is added to the core structure to encapsulate the key components. The protective shell 10 acts as a physical barrier, isolating the external environment. During transportation, movement, or use in harsh environments, the protective shell 10 naturally provides protection, protecting the internal precision and electrical components—batteries, motors, and wiring—from impacts, rain, and dust.

[0022] Specifically, the protective shell 10 has a horn structure 11 on one side and an interface cover 12 adapted to the charging port of the battery pack 9 on the other side. In this embodiment, the function of the protective shell 10 is expanded by integrating the horn 11 and the covered charging interface 12. The horn 11 can emit an alarm sound or voice command. The interface cover 12 is closed when not charging to prevent dust and water damage; it is opened when charging. This achieves an integrated sound and light alarm, enhancing the warning effect; at the same time, it facilitates and safely charges the built-in battery, enriching the device's functions and upgrading it from a single lighting system to a comprehensive emergency platform of "lighting + warning".

[0023] Specifically, the protective housing 10 is equipped with a remote control 13 connected to the emergency light 6 and the motor drive device 4 via a remote communication unit. This adds a remote control function, allowing the device to be controlled via the remote control 13. The remote control 13 connects to the receiving unit inside the device via wireless signals such as RF, Wi-Fi, or Bluetooth, allowing the user to send commands remotely. During use, operators can remotely turn the lights on / off, control the lifting and lowering of the lights, adjust the angle of the light head, and sound the horn from a safe distance. This enables remote wireless operation, improving operational convenience and personnel safety. In hazardous environments (such as fires or chemical spills), rescuers can operate the device without approaching it, greatly ensuring the personal safety of the operator, a key feature of modern intelligent emergency equipment.

[0024] Specifically, a bracket 14 is provided on the outer wall of the top of the positioning cylinder 2, and the bracket 14 has multiple positioning slots 15 that are adapted to the ends of the housing of the emergency light 6. A bracket 14 and positioning slots 15 for storing the emergency light 6 are added to the top of the positioning cylinder 2. When the lifting column descends to its lowest point, the end of the emergency light 6 falls precisely into the corresponding positioning slot 15. When the device is not in use, the light body is fully lowered, and the light head is reliably locked in the positioning slot 15. This provides a dedicated storage and fixing position for the emergency light 6 in its retracted state, avoiding damage caused by the light head shaking or collision during movement and transportation, thus providing excellent storage and protection.

[0025] Specifically, the motor drive device 4 includes a lifting drive motor 41 and a worm gear mechanism 42. The lifting column assembly 3 includes a primary lifting cylinder 31 and a secondary lifting cylinder 32. The primary lifting cylinder 31 is slidably disposed within the positioning cylinder 2. The inner wall of the positioning cylinder 2 is provided with a first vertical groove, and the outer wall of the primary lifting cylinder 31 is provided with a first slider adapted to the first vertical groove. The secondary lifting cylinder 32 is slidably disposed within the primary lifting cylinder 31. The inner wall of the primary lifting cylinder 31 is provided with a second vertical groove, and the outer wall of the secondary lifting cylinder 32 is provided with a second slider adapted to the second vertical groove. A support seat 21 is provided at the bottom inside the positioning cylinder 2. A first screw 22 is rotatably mounted on the support seat 21 via a double bearing assembly. The bottom end of the first screw 22 is synchronously connected to the worm gear of the worm gear mechanism 42. The bottom of the cylinder 31 is provided with a first mounting seat 33. The center of the first mounting seat 33 is provided with a first nut 34 that is adapted to the first screw 22. The bottom of the first mounting seat 33 is rotatably mounted with a first bushing 35 through a bearing assembly. The side of the first screw 22 is provided with a third vertical groove. The inner wall of the first bushing 35 is provided with a third slider that is slidably connected to the third vertical groove. The side of the first mounting seat 33 is rotatably mounted with a second screw 36 through a double bearing structure. The bottom of the second screw 36 and the first bushing 35 are provided with a gear transmission assembly 37. The bottom of the secondary lifting cylinder 32 is provided with a second mounting seat 38. The side of the second mounting seat 38 is provided with a second nut 39 that is adapted to the second screw 36. The lifting seat 5 is located at the top of the secondary lifting cylinder 32.

[0026] In this embodiment, a lifting drive motor 41, in conjunction with a worm gear mechanism 42, performs first-stage reduction and self-locking. A first screw 22 drives the first-stage lifting cylinder 31 to rise and fall. Innovatively, a first bushing 35, which can slide relative to the first screw 22 but transmit torque, is provided at the bottom of the first mounting base 33. A second screw 36 on the drive side is driven by a gear transmission assembly 37, thereby driving the second-stage lifting cylinder 32 to rise and fall, achieving double-stage lifting. The process is as follows: Lifting drive motor 41 → Worm gear mechanism 42 (reduction, torque increase, self-locking) → First screw 22 rotates → First nut 34 drives the first mounting base 33 and the first-stage lifting cylinder 31 to rise linearly → First bushing 35 rises with the first mounting base 33 and slides along the groove of the first screw 22, simultaneously transmitting rotational power to the second screw 36 via the gear set 37 → Second screw 36 rotates → Second nut 39 drives the second mounting base 38 and the second-stage lifting cylinder 32 to rise linearly relative to the first-stage lifting cylinder 31. This invention provides a multi-stage lifting mechanism with a compact structure, smooth transmission, high load capacity, and self-locking function (due to the characteristics of a worm gear), enabling a greater lifting stroke within a limited machine height. It achieves a balance between a low overall machine height (facilitating movement and storage) and a high working height (expanding the lighting range). The worm gear drive ensures a smooth and reliable lifting process and features self-locking capability in any position even without power, preventing slippage due to gravity and ensuring high safety. Specifically, the flipping mechanism 7 includes a hinge base 71 and a flipping motor 72 housed within the emergency light 6. A hinge shaft 73 is fixedly mounted on the hinge base 71, and a first reducer 74 is provided between the output end of the flipping motor 72 and the hinge shaft 73. The first reducer 74 includes a housing hinged to the hinge shaft 73 and a reduction gear assembly housed within the housing. The emergency light 6 can rotate around the hinge shaft 73. The flipping motor 72 outputs torque, which, after being reduced and increased by the first reducer 74, drives the housing to rotate slowly and precisely around the hinge shaft 73, thereby adjusting the pitch angle of the entire emergency light 6 with the hinge shaft 73 as the center. Users can control the forward and reverse rotation of the flipping motor 72 via a controller to precisely adjust the illumination angle of the lamp head, achieving electric, independent, and precise control of the illumination angle of each emergency light 6. This replaces manual adjustment, making operation more convenient and precise, and allowing for remote and accurate projection of light onto the most needed area, further improving lighting efficiency.

[0027] Specifically, the lifting seat 5 is a triangular plate structure, and three emergency lights 6 are installed on the lifting seat 5 in a triangular arrangement. Folding mechanisms 75 are provided on both sides of the lifting seat 5. Two of the emergency lights 6 are rotatably mounted on the two folding mechanisms 75 via hinge seats 71, and the third emergency light 6 is rotatably mounted on the lifting seat 5 located between the two folding mechanisms 75 via a hinge seat 71. The folding mechanism 75 includes a horizontally arranged folding motor 76 on the side of the lifting seat 5 and a second reducer 77 on the end face of the folding motor 76. The output shaft of the second reducer 77 is perpendicular to the output shaft of the folding motor 76. A folding seat 78 is fixedly mounted on the output shaft of the second reducer 77, and a hinge seat 71 for mounting the emergency light 6 is fixedly mounted on the folding seat 78. In this embodiment, the folding mechanism 75 consists of a folding motor 76, a second reducer 77, and a folding seat 78, enabling horizontal rotation. When the folding motor 76 operates, it drives the folding seat 78 to rotate horizontally through the second reducer 77 (whose output shaft has changed direction), thereby causing the emergency light 6 on it to fold or unfold horizontally.

[0028] When in operation, the lamp heads on both sides can be folded towards the center by the folding mechanism 75, which can adjust the unfolding range of the three emergency lights 6, adjust the illumination coverage area, and adjust the illumination intensity by closing the three emergency lights 6. This optimizes the lighting layout in the working state, greatly enhances the portability and versatility of the equipment, and is suitable for different usage needs.

[0029] Specifically, the frame 1 has protective rods 16 vertically installed at its four corners. A crossbeam 17 is connected to the top of each of the four protective rods 16. A vertical slide rail 18 is provided on the outer surface of each protective rod 16. A support foot 19 is slidably mounted within the vertical slide rail 18. A spring-loaded positioning pin 20 is provided between the support foot 19 and the vertical slide rail 18. By manually pulling out the spring-loaded positioning pin 20, the height of the support foot 19 on the vertical slide rail 18 can be adjusted. After adjustment, the spring-loaded positioning pin is inserted into the pin hole under the action of the spring to lock it in place.

[0030] Specifically, the frame 1 has two motor wheels 24 on both sides of one bottom end, two rollers 25 on both sides of the other bottom end, and a rail guide wheel 26 in the middle of both bottom ends. The motor wheels 24 provide driving force to move the equipment. The flange of the rail guide wheel 26 is engaged with the inside of the rail. In use: On flat ground, it moves like a regular cart. When it needs to travel along rails, the equipment is pushed onto the rails, and the middle guide wheel 26 engages with the rail, ensuring the equipment travels in a straight line without derailing. This greatly enhances the equipment's mobility and adaptability to different scenarios, making it a multi-functional emergency rescue device suitable for highways and railway tunnels.

[0031] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0032] The above embodiments only illustrate one or more implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
