Description

Technical Field

[0001] This utility model relates to the field of emergency equipment technology, specifically to an intelligent chain-controlled opening and closing mechanism for emergency lighting and communication vehicles. Background Technology

[0002] In scenarios such as power emergency repair and disaster relief, power emergency lighting and communication vehicles play a crucial role. They need to quickly provide lighting and establish communication links on-site, and, when necessary, utilize drones for aerial reconnaissance and delivery of relief supplies. The opening and closing mechanism of the vehicle's cover, as a pre-launch component for drones, is of paramount importance.

[0003] Currently, traditional emergency lighting and communication vehicle roofs use a manual opening and closing mechanism. In emergency rescue scenarios where every second counts, this manual operation is cumbersome, requiring operators to spend a significant amount of time and energy on repeated adjustments and operations, severely impacting emergency response speed and potentially missing the "golden time" for rescue. Later, a simple electric push rod was adopted to control the roof's opening and closing. While this control method achieves both automatic opening and closing, under the vibrations of prolonged vehicle travel and the bumps of rough road conditions, the roof is prone to loosening, wear, or even detachment, leading to poor opening and closing, or even complete malfunction, thus hindering drone takeoff and operations. Furthermore, the existing electric push rod control method only allows for simple opening and closing of the roof, failing to precisely adjust its position according to the actual operating environment and needs, and also making precise linkage with the lifting platform inside the vehicle difficult. Utility Model Content

[0004] The purpose of this utility model is to provide an intelligent chain-controlled opening and closing mechanism for emergency lighting and communication vehicles. Through the guide chain tube and high-precision drive components, the top cover can still operate stably under complex road conditions and severe weather, reducing the occurrence of failures. Through the cooperation of PLC with servo motors and sensors, the position of the top cover can be precisely controlled, and it can also be precisely linked with the lifting plate to provide sufficient safety for drones.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an intelligent chain-controlled opening and closing mechanism for an emergency lighting and communication vehicle, comprising a body and an avoidance hole on the top of the body. Two top covers for sealing the avoidance hole are horizontally slidably installed on the top of the body. Two guide tubes are symmetrically fixed on the inner wall of the top of the body. The guide tubes are equipped with driving components for driving the two top covers to slide simultaneously towards or away from each other. A first sensor for monitoring whether the top cover is fully closed is fixedly installed on the top wall of the body near the center. A second sensor for monitoring whether the top cover is fully open is fixedly installed on the top wall of the body near both sides.

[0006] Preferably, two slide rails are symmetrically arranged on the top of the compartment, a connecting frame is fixedly arranged between the tops of the two slide rails, and a top cover is fixedly arranged on the top of the connecting frame.

[0007] Preferably, two symmetrical fixing brackets are vertically fixed at the bottom of the connecting frame, and a metal plate is fixedly fixed on the outer side of the fixing brackets.

[0008] Preferably, the drive assembly includes a through hole on the side wall of the guide tube, a lower rack slidably disposed on the inner bottom wall of the guide tube, an upper rack slidably disposed on the inner top wall of the guide tube symmetrical to the lower rack, a flexible chain fixedly disposed at the end of both the lower and upper racks, the end of the flexible chain passing through the through hole and connected to a fixing frame, a rotating shaft rotatably disposed on the inner wall of the guide tube between the lower and upper racks, a gear fixedly disposed on the rotating shaft respectively cooperating with the lower and upper racks, two worm gear seats symmetrically disposed on one side of the gears on the inner bottom wall of the guide tube, a worm rotatably disposed between the two worm gear seats, a servo motor fixedly disposed at one end of the worm on the bottom wall of the guide tube, the servo motor being connected to a PLC controller via a signal line, and a worm wheel cooperating with the worm fixedly disposed on the rotating shaft on one side of the gears.

[0009] Preferably, a first sensor that engages with a metal plate when the top cover is closed is fixedly installed on the top wall near the middle of the compartment, and a second sensor that engages with a metal plate when the top cover is opened is fixedly installed on the top walls near both sides of the compartment. Both the first and second sensors are connected to a PLC controller via signal lines.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. In this utility model, the strength and stability of the top cover connecting parts are enhanced by the cooperation of the high-strength guide chain tube on the body and the flexible chain in the high-precision drive assembly. This effectively resists interference from external factors such as vehicle driving vibration and severe weather, ensuring that the top cover can open and close smoothly under various complex working conditions, and providing reliable protection for the take-off of the drone.

[0012] 2. In this utility model, the flexible chain is precisely controlled by the cooperation of the PLC controller and the servo motor, so as to achieve fine adjustment of the opening and closing degree of the top cover, which can flexibly adapt to the needs of different weather conditions and operation scenarios. In addition, through the cooperation of the PLC controller and the sensor, it can achieve precise linkage with the lifting plate, providing sufficient safety guarantee for the drone.

Detailed Implementation

[0022] 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.

[0023] like Figure 1-7 As shown, the intelligent chain-controlled opening and closing mechanism of the emergency lighting and communication vehicle includes a compartment 1, combined with... Figure 2 As shown, the top of the compartment 1 has an clearance hole 2, and two slide rails 3 are symmetrically arranged on the top of the compartment 1. A connecting frame 4 is fixedly installed between the tops of the two slide rails 3. Figure 2 and Figure 4As shown, two symmetrical fixing brackets 6 are vertically fixed at the bottom of the connecting frame 4, and a metal plate 7 is horizontally fixed on the outer side of the fixing bracket 6. A top cover 5 for sealing the avoidance hole 2 is fixed at the top of the connecting frame 4.

[0024] Specifically in this embodiment, combined with Figure 3 As shown, two guide tubes 8 are symmetrically fixed on the inner top wall of the compartment 1. Preferably, the guide tubes 8 are square hollow structures, and the guide tubes 8 are equipped with driving components 9 for driving the two top covers 5 to slide simultaneously towards or away from each other. Furthermore, combined with Figure 5 , Figure 6 and Figure 7 As shown, the drive assembly 9 includes a through hole 901 formed in the side wall of the guide tube 8. Slide tracks 902 are provided on both the bottom and top inner walls of the guide tube 8. A lower rack 903 is slidably mounted on the slide track 902 on the bottom wall of the guide tube 8, and an upper rack 904, symmetrical to the lower rack 903, is slidably mounted on the slide track 902 on the top wall of the guide tube 8. Flexible chains 905 are fixedly mounted at the ends of both the lower rack 903 and the upper rack 904. The end through-hole 901 connects to the fixing frame 6. It should be noted that the flexible chain 905 is designed to bend only to one side. The through-hole 901 is positioned at a certain angle to the fixing frame 6 on the same horizontal plane. This angled arrangement ensures that the flexible chain 905 bears force on its non-bendable side as it moves out of the guide tube 8, preventing bending of the flexible chain 905 when the top cover 5 is closed. The inner wall of the guide tube 8... A rotating shaft 906 is rotatably mounted between the lower rack 903 and the upper rack 904. Gears 907, which respectively mesh with the lower rack 903 and the upper rack 904, are fixedly mounted on the rotating shaft 906. Two worm gear seats 908 are symmetrically arranged on one side of the gear 907, on the inner bottom wall of the guide tube 8. A worm 909 is rotatably mounted between the two worm gear seats 908. It should be noted that when the worm 909 meshes with the worm gear seat 908, the worm 909 is positioned within the worm gear seat 908. There will be no displacement. One end of the worm 909 is provided with a servo motor 910 fixed on the bottom wall of the guide tube 8. The servo motor 910 is connected to the PLC controller through a signal line. It should be noted that the PLC controller is prior art and is not a technical feature to be protected in this application. It can be obtained by purchase. Therefore, it will not be described in detail here. A worm wheel 911 that cooperates with the worm 909 is fixedly provided on the rotating shaft 906 and located on one side of the gear 907.

[0025] Preferably, the high-strength guide pipe 8 on the body 1 and the flexible chain 905 in the high-precision drive assembly 9 enhance the strength and stability of the connecting parts of the top cover 5, effectively resist the interference of external factors such as vehicle driving vibration and severe weather, and ensure that the top cover 5 can open and close smoothly under various complex working conditions, providing a reliable guarantee for the take-off of the drone.

[0026] Specifically in this embodiment, combined with Figure 2 and Figure 3 As shown, a first sensor 10 is fixedly installed on the top wall near the middle of the compartment 1, which engages with the metal plate 7 when the top cover 5 is closed. Second sensors 11 are fixedly installed on the top walls near the sides of the compartment 1, which engage with the metal plate 7 when the top cover 5 is open. Both the first sensor 10 and the second sensor 11 are connected to a PLC controller via signal lines. When the first sensor 10 engages with the metal plate 7, the top cover 5 is completely closed. At this time, the first sensor 10 transmits a signal to the PLC controller. After receiving the signal, the PLC controller processes it and controls the servo motor 910 to stop. The rotation is stopped, and the flexible chain 905 is stopped from being output outward from the guide tube 8. When the second sensor 11 cooperates with the metal plate 7, the top cover 5 is fully opened. At this time, the signal is transmitted to the PLC controller through the second sensor 11. After receiving the signal, the PLC controller processes it and controls the servo motor 910 to stop rotating, and stops the input of the flexible chain 905 into the guide tube 8. In addition, when the lifting plate in the compartment 1 is not fully lowered into place, the servo motor 910 is not controlled to prevent the risk of the top cover 5 colliding with the drone due to the lifting plate not being fully lowered into place when the top cover 5 is closed.

[0027] Working principle:

[0028] In use, the servo motor 910 is first controlled to rotate forward using an external control button or remote control. When the servo motor 910 rotates forward, it drives the lower rack 903 and the upper rack 904 to slide towards the center within the guide tube 8. The sliding of the lower rack 903 and the upper rack 904 towards the center drives the two top covers 5 to slide back and forth via the flexible chain 905. When the top cover 5 slides to the point where the metal plate 7 engages with the second sensor 11, the servo motor 910 stops working, allowing the top cover 5 to open completely. At this point, the lifting plate inside the compartment 1 can be controlled to slide upward. When the lifting plate slides upward to be flush with the top cover 5, it stops, forming a large lifting platform with the lifting plate and the two top covers 5. It should be noted that when the two top covers 5 are not fully open, the lifting system of the lifting plate is in a power-off state. The drone on the lifting plate is protected by the PLC interlock to prevent damage to the drone when the lifting plate is sliding upward while the top cover 5 is not fully open.

[0029] After use, the drone is first lowered onto the lifting platform, and then the platform is reset. Once reset, the servo motor 910 is reversed via a control button or remote control. This reverse rotation drives the lower rack 903 and upper rack 904 to slide outwards within the chain guide tube 8. As they slide outwards, the flexible chain 905 within the chain guide tube 8 is pushed out through the through hole 901, driving the two top covers 5 to slide relative to each other. When the top cover 5 slides until the metal plate 7 engages with the first sensor 10, the servo motor 910 stops, closing the top cover 5. It is important to note that if the lifting platform is not fully reset, the servo motor 910 is de-energized and cannot be controlled. This prevents damage to the drone from the top cover 5 closing if the lifting platform is not fully reset.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
