Description

Technical Field

[0001] This invention relates to the field of door systems for urban rail transit vehicles, and more particularly to a concealed door. Background Technology

[0002] Urban rail transit vehicle door systems often employ double-sliding doors. In practice, it has been found that certain trains require the addition of concealed doors that are not visible from the inside, in addition to the existing double-sliding doors. Current technology cannot directly install these concealed doors from the outside; the train body must be opened, resulting in a noticeable concealed door that fails to achieve the desired concealment and impacts subsequent use. Therefore, a novel concealed door structure needs to be developed to meet this requirement. Summary of the Invention

[0003] Purpose of the invention: To address the shortcomings and defects of existing technologies, this invention provides a concealed car door that can be installed from the outside when the vehicle body is not open; not only is it invisible from the inside, but the fasteners installed are also invisible from the outside of the vehicle. The appearance of the concealed car door is consistent with that of a normal double sliding door in the closed state.

[0004] Technical Solution: The concealed car door of the present invention is characterized by: comprising left and right door panels, with a central seam between the door panels separated by a central adhesive strip, peripheral adhesive strips around the door panels, and glass on the door panels; the left and right door panels have 26 mounting points, and the door panels are connected to the vehicle body by mounting screws passing through the mounting points; the connection between the door panels and the vehicle body is adjusted by adjusting shims to ensure that the door panels are flush with the outer surface of the vehicle body after installation; the peripheral profile of the door panel frame is provided with barbed adhesive strip mounting grooves and inclined surfaces simulating sealing frames, and the peripheral adhesive strips are installed in the corresponding adhesive strip mounting grooves; the central seam profile of the door panel frame is also provided with adhesive strip mounting grooves, and the central adhesive strip is installed in the corresponding adhesive strip mounting grooves.

[0005] The glass is bonded and installed on the door leaf.

[0006] The door leaf and the vehicle body are sealed with adhesive.

[0007] The peripheral rubber strip is a one-piece vulcanized rubber strip.

[0008] The peripheral rubber strip is installed in the rubber strip mounting groove of the door panel by tapping it from the outside with a rubber hammer.

[0009] The middle rubber strip has a 2mm gap on the outside, which simulates the gap between the left and right finger guards of a normal sliding door.

[0010] The vehicle body has no open doorway, but only a recessed doorway. The vehicle body is provided with threaded holes, and each threaded hole corresponds to an installation point.

[0011] The peripheral and intermediate rubber strips, once installed, cover the 26 mounting screws on the door leaf, making the installation points invisible from the outside, thus simulating the peripheral and finger-protecting rubber strips of a normal sliding door.

[0012] Beneficial Effects: Compared with existing technologies, this invention has the following significant advantages: A concealed door can be installed from the outside without opening the vehicle body; not only is it invisible from the inside, but the fasteners are also invisible from the outside of the vehicle. The appearance of the concealed door is consistent with that of a normal double-opening sliding door in its closed state. The door panel of this invention is a single, integral structure, installed from the outside, resulting in a simple structure. The peripheral and central rubber strips can be installed into the rubber strip grooves from the outside by tapping, solving the installation problem while concealing the door panel's mounting screws, making it aesthetically pleasing and easy to install.

Detailed Implementation

[0020] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] The concealed car door of the present invention includes left and right door panels 1, with a central seam between the door panels 1 separated by a central adhesive strip 3. A peripheral adhesive strip 2 is provided around the door panels 1, and glass is provided on the door panels 1. The left and right door panels 1 have 26 mounting points 11. The door panels 1 are connected to the vehicle body 7 by mounting screws 8 passing through the mounting points 11. The connection between the door panels 1 and the vehicle body 7 is adjusted by adjusting shims 9 to ensure that the door panels 1 are flush with the outer surface 4 of the vehicle body after installation. The peripheral profile of the door panel 1 frame is provided with barbed adhesive strip mounting grooves 6 and beveled surfaces simulating a sealing frame, and the peripheral adhesive strips 2 are installed in the corresponding adhesive strip mounting grooves 6. Similarly, the central seam profile of the door panel 1 frame is provided with adhesive strip mounting grooves 6, and the central adhesive strip 3 is installed in the corresponding adhesive strip mounting groove 6.

[0022] The glass of this invention is bonded and installed on the door leaf 1. A sealing joint 5 is formed between the door leaf 1 and the vehicle body 7. The peripheral rubber strip 2 is a single, vulcanized rubber strip. The peripheral rubber strip 2 is installed into the rubber strip mounting groove 6 of the door panel by tapping it from the outside with a rubber hammer. The middle rubber strip 3 has a 2mm gap 10 on its exterior, visually simulating the gap between the left and right finger guard rubber strips of a normal sliding door. The door opening of the vehicle body 7 is not open, but only recessed. The vehicle body has threaded holes, each corresponding to a mounting point 11. After the peripheral rubber strip 2 and the middle rubber strip 3 are installed, they cover the 26 mounting screws 8 of the door leaf 1, making the mounting point 11 invisible from the outside, thus simulating the peripheral rubber strip and finger guard rubber strip of a normal sliding door.

[0023] This invention allows for the installation of a concealed door from the outside without opening the vehicle body. Not only is it invisible from the inside, but the fasteners are also invisible from the outside of the vehicle. The concealed door's appearance is identical to a normal double-opening sliding door in its closed state. The door panel of this invention is a single, integral structure, installed from the outside, resulting in a simple design. The peripheral and central rubber strips can be easily installed into the grooves from the outside by tapping, solving the installation problem while concealing the mounting screws, making it both aesthetically pleasing and easy to install.
