[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figures 1-4 , the utility model provides a technical solution:

[0025] Example 1:

[0026] A curtain assembly structure for a train includes a first upper beam 101 and a second upper beam 102. As the main supporting components of the curtain assembly structure, they provide a stable foundation, ensuring smooth installation and operation of the curtain. The double upper beam design may increase the stability and load-bearing capacity of the structure.

[0027] The upper surfaces of upper beam 101 and upper beam 2 102 are connected by a clamping block 103, which is used to connect upper beam 101 and upper beam 2 102 to ensure a tight connection between the two. A fixing plate 202 is provided on the upper surface of upper beam 101 and upper beam 2 102 to further strengthen the connection between the upper beams. The back of upper beam 2 102 is fixedly connected to a mounting plate 2, and both ends of the mounting plate 2 are threadedly connected to the car body by bolts 1 201. A shock-absorbing pad is provided on the mounting plate 2, and the mounting plate 2 is used to firmly fix the curtain assembly structure on the car body, while the shock-absorbing pad can reduce the impact of vibration during vehicle driving on the curtain structure. A rolling curtain mechanism is provided under the two upper beams;

[0028] The rolling shutter mechanism includes a light-transmitting unit and a light-blocking unit;

[0029] The light-transmitting unit includes a curtain body 401, a spring 402, a stopper 403, a lower rod 404, and a reel 405. The curtain body 401 is wound around the outer layer of the reel 405, providing light-blocking or light-transmitting functions, and can meet different lighting requirements depending on the material and design. The spring 402 is set inside the reel 405, providing power for the automatic rewinding of the curtain, making the curtain operation more convenient. The stopper 403 is set on the left side of the reel 405, and a slot is provided on the top of the lower rod 404. The bottom of the curtain body 401 is inserted into the slot of the lower rod 404. The lower rod 404 is made of aluminum alloy to prevent the curtain body 401 from excessive movement on the reel 405, while making it easier for passengers to exert downward force on it.

[0030] Example 2:

[0031] Based on Example 1, the light-transmitting unit and the light-blocking unit have the same structure. There are two sets of light-transmitting units and light-blocking units, respectively, located on either side of the bottom surface of upper beam 101 and upper beam 2 102 and separated by a partition 5. This separates the light-transmitting unit and the light-blocking unit, allowing them to operate independently without interfering with each other, improving flexibility and convenience. The light-transmitting unit and light-blocking unit are threadedly connected to upper beam 101 and upper beam 2 102, respectively, via bolts 301 on bracket 3. Bolts 301 securely mount the rolling curtain mechanism to the upper beams, ensuring stable operation. The design of bracket 3 may also take into account ease of installation and removal. Both the light-transmitting gauze and the light-blocking cloth are treated with mildew-proof, dust-proof, and anti-static treatments to effectively prevent mold growth, dust accumulation, and static electricity generation, maintaining the cleanliness and service life of the curtains while enhancing the passenger experience. Passengers can choose to use either the light-transmitting unit or the light-blocking unit as needed. Since both operate independently, passengers can easily switch between different curtain modes to meet their varying lighting needs.

[0032] Working Principle: Initially, the curtain is typically fully rolled up and rests snugly on the reel 405. At this point, the spring 402 is uncompressed, at its original length or slightly stretched. The passenger grasps the lower rod 404 and pulls downward. As the curtain gradually unfurls, the reel 405 begins to rotate, releasing the curtain body 401. As the curtain unfurls, the spring 402 within the reel 405 encounters resistance from the curtain body and gradually compresses. This process stores energy, ready to be released when the curtain is released.

[0033] The degree of curtain expansion is typically controlled by the passenger. When the curtain reaches the desired position, the passenger can stop pulling it down. At this point, a stop pin attached to the reel contacts a stop slot on the reel when the curtain reaches the desired position, preventing further rotation of the reel 405 and keeping the curtain in place. To close the curtain, the passenger simply gently releases the lower edge of the curtain or lower rod 404. Without external force, the curtain is no longer subject to downward tension.

[0034] At this time, the previously compressed spring 402 begins to release stored energy. The thrust of the spring 402 acts on the reel 405, causing it to start rotating and rolling up the curtain body 401. As the spring continues to release energy, the curtain gradually and automatically rewinds onto the reel 405.

[0035] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising a..." does not exclude the presence of additional identical elements in the process, method, article, or device comprising the element.
