Description

Technical Field

[0001] This utility model relates to the field of urban rail transit electromechanical equipment technology, specifically a subway electromechanical optical environment gradient balancing device. Background Technology

[0002] In subway electromechanical systems, intelligent adjustment of the lighting environment is crucial for passenger experience and operational efficiency. Existing subway lighting environment gradient balancing devices mostly adopt traditional electromechanical equipment architectures, and their installation methods have significant shortcomings in adaptability to subway spaces, especially in complex decoration environments, irregularly shaped areas, and scenarios requiring rapid assembly and disassembly.

[0003] During subway operation, sudden malfunctions of lighting environment devices require rapid handling. However, traditional structures rely on multiple tools such as screwdrivers and wrenches for disassembly, and replacing a single unit takes a long time. Furthermore, after reinstallation, the light sensor needs to be manually calibrated. The lack of modular design makes component-level maintenance difficult. For example, if the dimming module fails, the entire device needs to be replaced, resulting in a high rate of material waste and a low recycling rate for old devices, which does not meet the requirements of green construction. Utility Model Content

[0004] The purpose of this invention is to provide a subway electromechanical optical environment gradient balancing device to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides a subway electromechanical optical environment gradient balancing device, including a device body and a ceiling, a mounting block fixedly installed on the outer wall of the device body, a trapezoidal block provided on one side of the mounting block, a first elastic element provided between the mounting block and a first elastic element, the first elastic element being V-shaped, the inner top wall and inner bottom wall of the first elastic element, the trapezoidal block having a trapezoidal cross-section and being rotatably mounted on the inner top wall and inner bottom wall of the first elastic element, the two mounting plates being hinged, a torsion spring provided between the two mounting plates; and a locking block fixedly installed on the inner wall of the ceiling.

[0006] Furthermore, a damper and a tension spring are installed between the mounting block and the trapezoidal block, with the tension spring sleeved on the outside of the damper.

[0007] Furthermore, an arc-shaped elastic element is installed between the top of the mounting block and the trapezoidal block. The arc-shaped elastic element is arranged in an arc shape and is positioned above the first elastic element, the damper, and the tension spring.

[0008] Furthermore, both the first elastic element and the arc-shaped elastic element are made of spring steel.

[0009] Furthermore, a pull rope is installed on one side of the trapezoidal block, and a rotating rod is rotatably arranged inside the device body. The other end of the pull rope is wrapped around the outer wall of the rotating rod, and a square block is fixedly installed at the bottom end of the rotating rod.

[0010] Furthermore, the dampers and tension springs are evenly distributed at the four corners of the mounting block.

[0011] Furthermore, a sponge layer is provided on the square block.

[0012] Furthermore, the inclined surface of the trapezoidal block is provided with multiple ball bearings.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, the device body is connected to the ceiling via an installation block. A trapezoidal block is inserted into a locking block, and the V-shaped first elastic element is compressed to generate a clamping force. The hinged installation plate is opened under the action of a torsion spring, causing the trapezoidal block to engage with the locking block. During disassembly, rotating the rotating rod tightens the pull rope, pulling the trapezoidal block to compress the first elastic element and release the engagement. The cooperation between the first elastic element and the torsion spring enables tool-free quick installation and disassembly, avoiding damage to the ceiling finish, shortening the disassembly time per workstation, and improving maintenance efficiency.

[0015] 2. In this utility model, the multiple balls on the inclined surface of the trapezoidal block can convert the sliding friction between the trapezoidal block and the locking block into rolling friction, which significantly reduces the resistance during installation and disassembly, making the process of inserting or disengaging the trapezoidal block from the locking block smoother, reducing component wear caused by excessive frictional resistance, and ensuring that the trapezoidal block and the locking block quickly and accurately engage, improving the installation efficiency and connection stability of the device. The ball bearings can also adapt to slight angular deviations, enhancing the adaptability of the device to different installation environments. Attached Figure Description

[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] Please see Figures 1-5 This utility model provides a technical solution:

[0024] See Figures 1-5 As shown, a subway electromechanical optical environment gradient balancing device includes a device body 1 and a ceiling 2, a mounting block 3 fixedly installed on the outer wall of the device body 1, a trapezoidal block 5 provided on one side of the mounting block 3, a first elastic element 4 provided between the mounting block 3 and the first elastic element 4, the first elastic element 4 being V-shaped, the inner top wall and inner bottom wall of the first elastic element 4, and the trapezoidal block 5 having a trapezoidal cross-section; mounting plates 6 rotatably mounted on the inner top wall and inner bottom wall of the first elastic element 4, the two mounting plates 6 being hinged, and a torsion spring 12 provided between the two mounting plates 6; and a locking block 11 fixedly installed on the inner wall of the ceiling 2.

[0025] The device body 1 is connected to the ceiling 2 via the mounting block 3. The trapezoidal block 5 on one side of the mounting block 3 is inserted into the locking block 11 on the inner wall of the ceiling 2. The V-shaped first elastic element 4 is deformed under pressure to generate a lateral clamping force. At the same time, the two hinged mounting plates 6 are pushed outward under the action of the torsion spring 12, so that the trapezoidal block 5 and the locking block 11 are tightly engaged. When disassembly is required, the rotating rod 13 is rotated to tighten the pull rope, pull the trapezoidal block 5 towards the mounting block 3, compress the first elastic element 4 and release the engagement state of the locking block 11, so that the device body 1 can be quickly removed.

[0026] Through the elastic cooperation between the first elastic element 4 and the torsion spring 12, the device body 1 and the ceiling 2 can be quickly installed and disassembled without tools. No bolts are required during installation, which avoids damage to the decorative surface of the ceiling 2. The single-station operation time can be shortened during disassembly, which significantly improves maintenance efficiency.

[0027] The combination of damper 8 and tension spring 9 can absorb the vibration energy during subway operation and prevent the device from loosening due to high-frequency vibration. The arc-shaped elastic element 10 further enhances the stability of the top support, ensuring that the device can operate reliably for a long time in complex environments, which meets the requirements of subway electromechanical equipment for ease of installation, environmental adaptability and structural stability.

[0028] See Figure 5 A damper 8 and a tension spring 9 are installed between the mounting block 3 and the trapezoidal block 5, with the tension spring 9 sleeved on the outside of the damper 8.

[0029] The combined structure of damper 8 and tension spring 9 can absorb the vibration energy generated during subway operation, preventing the device from becoming loose due to high-frequency vibration. Tension spring 9 provides elastic restoring force to maintain the stable engagement of trapezoidal block 5 and locking block 11. The sleeved arrangement allows the two to work together. Damper 8 suppresses spring oscillation, ensuring the device can operate reliably for a long time in dynamic environments. At the same time, this structure allows for small displacement compensation between mounting block 3 and trapezoidal block 5, improving the device's adaptability to the deformation of ceiling 2, reducing component damage caused by structural stress concentration, and extending the service life of the device.

[0030] See Figure 3 An arc-shaped elastic element 10 is installed between the top of the mounting block 3 and the trapezoidal block 5. The arc-shaped elastic element 10 is arranged in an arc shape and is positioned above the first elastic element 4, the damper 8, and the tension spring 9.

[0031] The arc-shaped elastic element 10 can form an elastic support between the top of the mounting block 3 and the trapezoidal block 5, enhancing the overall stability of the device. It is located above the first elastic element 4, the damper 8, and the tension spring 9, which can effectively disperse the pressure from the top and avoid structural deformation due to excessive local stress. At the same time, the arc-shaped design provides a buffer space to adapt to the irregular surface of the ceiling 2, ensuring the fitting accuracy of the trapezoidal block 5 and the locking block 11, improving the adaptability of the device to irregular installation environments. It works in conjunction with the elastic components below to form a multi-layer vibration reduction structure, reducing the impact of subway vibration on the device and ensuring the stable operation of the light environment adjustment function.

[0032] See Figure 3 Both the first elastic element 4 and the arc-shaped elastic element 10 are made of spring steel.

[0033] The first elastic element 4 and the arc-shaped elastic element 10, made of spring steel, have high elastic modulus and fatigue resistance. They can maintain stable elastic deformation capacity during frequent installation and disassembly, ensuring reliable engagement between the trapezoidal block 5 and the locking block 11. At the same time, they resist high-frequency vibration in the subway environment, reduce elastic decay caused by material fatigue, and extend the service life of the device. Their good corrosion resistance is suitable for the humid environment of the subway, avoiding the impact of oxidation and rust on elastic performance, and ensuring the structural stability and installation reliability of the device during long-term operation.

[0034] See Figure 2 A pull rope is installed on one side of the trapezoidal block 5. A rotating rod 13 is rotatably installed inside the device body 1. The other end of the pull rope is wrapped around the outer wall of the rotating rod 13. A square block 7 is fixedly installed at the bottom end of the rotating rod 13.

[0035] The pull rope on one side of the trapezoidal block 5 is wound around the rotating rod 13 inside the device body 1. By rotating the rotating rod 13, the pull rope can be tightened or released, thereby driving the trapezoidal block 5 to move or reset towards the mounting block 3, realizing the quick unlocking and locking of the trapezoidal block 5 and the locking block 11. The square block 7 is fixed at the bottom of the rotating rod 13, which is convenient for the operator to manually rotate the rotating rod 13. The disassembly and installation of the device can be completed without additional tools, simplifying the operation process and improving maintenance efficiency. This structure uses the pull rope transmission to realize the transmission of force, which can avoid damage caused by direct force applied to the elastic element, while ensuring the smooth movement of the trapezoidal block 5, ensuring the reliability of the device connection and the convenience of operation.

[0036] See Figure 3 The dampers 8 and tension springs 9 are evenly distributed at the four corners of the mounting block 3.

[0037] The dampers 8 and tension springs 9 are evenly distributed at the four corners of the mounting block 3, which makes the device more evenly stressed during installation, avoiding tilting or deformation caused by uneven local stress, ensuring stable engagement between the trapezoidal block 5 and the locking block 11. At the same time, the symmetrical arrangement at the four corners can effectively absorb vibration energy from different directions, improve the stability of the device in the complex vibration environment of the subway, reduce loosening of connections caused by vibration, and the evenly distributed structure facilitates quick alignment and positioning during installation, improves installation efficiency, and ensures long-term reliable operation of the device.

[0038] See Figure 2 A sponge layer is provided on square block 7.

[0039] The sponge layer on the square block 7 increases the friction when the operator manually rotates the lever 13, preventing slippage and providing a soft touch to improve operating comfort. The cushioning effect of the sponge layer also reduces rigid collisions between the lever 13 and other components when rotating, reducing noise. In addition, the sponge material is lightweight and easy to replace, and can withstand long-term operation wear, ensuring the convenience of device maintenance and user experience.

[0040] See Figure 5 The inclined surface of trapezoidal block 5 is provided with multiple ball bearings.

[0041] Multiple balls on the inclined surface of trapezoidal block 5 can convert the sliding friction between trapezoidal block 5 and locking block 11 into rolling friction, significantly reducing the resistance during installation and disassembly, making the process of trapezoidal block 5 inserting into or disengaging from locking block 11 smoother, reducing component wear caused by excessive frictional resistance, and ensuring that trapezoidal block 5 and locking block 11 quickly and accurately engage, improving the installation efficiency and connection stability of the device. The ball bearings can also adapt to slight angular deviations, enhancing the device's adaptability to different installation environments.
