Description

Technical Field

[0001] The present application relates to the field of rail vehicles, and in particular to an interior side wall plug-in installation structure. Background Art

[0002] Currently, the interior side walls of urban rail vehicles primarily consist of side wall panels, door pillar covers, passenger compartment seats, and screens. The side wall panels are connected to the T-slots on the vehicle's door pillars via fasteners. Once installed, the door pillar covers shield the fasteners used to mount the side wall panels. The passenger compartment seats and screens are located between the two door pillar covers. Both sides of the side wall panels are fastened to the vehicle's door pillar profiles via fasteners. One side of the door pillar cover seals the passenger compartment door with fasteners, while the other side is flanged inward to shield the fasteners used to mount the side wall panels. The door pillar cover is secured to the passenger compartment surface via door handrail mounting brackets. The seats and screens are located on the inner sides of the two door pillar covers.

[0003] The arrangement of seats and screens in the passenger compartment is affected by the size of the vehicle body module. When the size of the vehicle body module becomes smaller and the size between the two door pillar covers is smaller than the space required for the arrangement of seats and screens, the passenger compartment seats, screens and other equipment will not be able to be arranged according to normal requirements. The door pillar cover of the existing interior side wall structure is only connected to the seal of the passenger compartment door by fasteners on one side. The door pillar cover can only be pressed against the side wall on the passenger compartment surface by the clamping force provided by the door handrail after installation. There are no installation points between the door pillar cover and the side wall panel of this structure. Therefore, after installation and tightening, the door pillar cover is prone to the undesirable state of overall tilting to one side, and there is an uneven gap between the door pillar cover and the side wall panel. This phenomenon is difficult to adjust through technological means, which has a great impact on the appearance of the entire vehicle. Summary of the Invention

[0004] The technical problem to be solved by this patent is to overcome the shortcomings of the above-mentioned existing technology and provide an internal side wall plug-in installation structure.

[0005] The technical solution adopted by this patent to solve its technical problems is: an interior side wall plug-in installation structure, including: a vehicle body door pillar, a side wall panel and a door pillar cover panel, characterized in that it also includes a transfer profile that is plugged and fixed to the vehicle body door pillar, the transfer profile has a first slot facing the door pillar cover panel, the inner side edge of the door pillar cover panel is fixed by inserting into the first slot, the transfer profile has an extended edge facing the side wall panel, and the side wall panel is pressed and fixed to the vehicle by the extended edges of the transfer profiles on both sides.

[0006] The interior side wall plug-in installation structure of the present invention eliminates the influence of the width of the door pillar cover panel being restricted by the side wall panel installation point through the connection method of connecting the adapter profile to the vehicle body door pillar. The distance L between the adapter profiles is the space available for arranging passenger compartment seats. The dimension L can be increased by changing the cross-section of the profile, thereby expanding the space available for arranging passenger compartment seats on the passenger side.

[0007] After the sidewall panels are in place, the original fastener-based method is replaced with a fastening method that compresses the sidewall panels using adapter profiles. The adapter profiles are connected to the vehicle body via slots. Because the adapter profiles are directly molded from a mold, their overall flatness far exceeds that of door pillar covers manufactured using sheet metal bending and welding processes. The structure of this invention ensures a uniform and minimal gap between the adapter profiles and the sidewall panels, significantly improving the appearance quality after installation and increasing installation efficiency.

[0008] The adapter profile of this invention includes a slot for securing the door pillar cover. The door pillar cover can be directly connected to the adapter profile by plugging, while the other side remains fastened to the passenger door seal. This mounting structure secures the door pillar cover on both sides, effectively resolving the issue of tilting the door pillar cover after installation. The gap between the door pillar cover and the side roof panel is uniform, improving overall vehicle installation quality.

[0009] Furthermore, an interior side wall plug-in installation structure also has a screen, and the adapter profile has a second slot facing the screen, and the glass of the screen is directly inserted into the second slot for fixation; the adapter profile has a through hole for accommodating the fixing seat of the screen to pass through, and the fixing seat of the screen passes through the through hole on the adapter profile and is fixed to the vehicle door pillar.

[0010] The present invention reserves a screen glass slot on the transition profile, and the screen glass can be directly plugged into the transition profile through the slot. At the same time, the screen fixing seat can be extended to the vehicle body for reinforcement at any position by opening a hole in the transition profile to enhance the structural stability and firmness of the screen.

[0011] Furthermore, a plug-in slot is provided on the side of the vehicle door pillar facing the adapter profile, and the plug-in slot has a pair of slot walls, and the slot walls have hooks and stops protruding outward from the outside to the inside. The adapter profile has two plug-in plates that match the plug-in slot, and the front part of the plug-in plate has a wedge block with an inclined surface facing outward. The stop blocks the wedge block for limiting the position, and the tail of the wedge block is suitable for being clamped by the hook to prevent it from falling off.

[0012] The novel interior side wall plug-in installation structure of the present invention can still achieve the requirements of arranging door pillar covers, screens and a sufficient number of seats when the body module size is small, without compressing the passengers' usable space, thereby improving the passengers' riding comfort.

[0013] The structure of the present invention can be used to install interior side walls on any type of rail vehicle where space is insufficient for internal seat placement. The structure is simple to install and easy to operate, and after installation, no repeated adjustments are required to address gaps or cover tilt. This structure is economical, saves labor costs and installation time, improves work efficiency, and has broad application prospects. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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.

[0020] like Figures 1 to 3 As shown, the interior side wall plug-in mounting structure of the present invention comprises: a vehicle door pillar 1, a side wall panel 2, a door pillar cover 4, a screen 6, a seat 5, and a transition profile 3 that is plugged and fixed to the vehicle door pillar 1. The distance L between adjacent vehicle doors between the transition profiles 3 represents the space for passenger compartment seat arrangement. This dimension L can be increased by changing the profile's cross-section, thereby expanding the space available for passenger compartment seat arrangement.

[0021] In this embodiment, the side of the vehicle door pillar 1 facing the adapter profile 3 is provided with an insertion slot 11. This slot 11 comprises a pair of walls, which, from the outside inward, form a protruding hook 111 and a stop 112. The adapter profile 3 is extruded and molded using a die, resulting in an overall flatness far superior to door pillar covers manufactured using sheet metal bending and welding processes. This structure ensures a uniform and minimal gap between the adapter profile and the sidewall, significantly improving the appearance and efficiency of the installed structure.

[0022] The adapter profile 3 has two plug-in plates 34 that mate with the insertion slots 11. The front of the plug-in plates 34 has a wedge-shaped block 341 with an outwardly inclined surface. The stopper 112 blocks the wedge-shaped block 341 for position limiting. The tail of the wedge-shaped block 341 is adapted to be caught by the hook 111 to prevent it from falling out. This allows the adapter profile to be inserted smoothly and is not easily loosened. The retaining edge also prevents the adapter profile from moving forward, acting as a position limiter.

[0023] The adapter profile 3 has a first slot 31 facing the door pillar cover 4 and an extended edge 32 facing the side wall 2. The adapter profile 3 also has a second slot 33 facing the screen 6. The inner edge of the door pillar cover 4 is secured by inserting into the first slot 31, while the outer edge of the door pillar cover 4 is fastened to the passenger compartment door seal. To ensure a more effective connection, a soft non-metallic material such as a rubber strip can be placed in the first slot 31 to ensure a secure and noise-free connection. The other side is connected to the door seal via fasteners.

[0024] The side wall panels 2 are fixed to the vehicle by means of the extension edges 32 of the adapter profiles 3 on both sides. The glass of the screen 6 is directly inserted into the second slots 33 for fixing.

[0025] The adapter profile 3 is provided with a through hole for the fixing seat of the screen 6 to pass through. The fixing seat of the screen 6 passes through the through hole on the adapter profile 3 and is fixed to the vehicle door pillar 1. The screen fixing seat is extended to the vehicle body for reinforcement to enhance the structural stability and firmness of the screen.

[0026] The installation method of the interior side wall of this embodiment is implemented by the above-mentioned installation structure, and specifically includes the following steps:

[0027] Step 1: Install and position the side wall panel 2 first;

[0028] Step 2: Insert the adapter profiles 3 on both sides into the insertion slots 11 of the vehicle door pillars 1, respectively, so that the side wall panels 2 are pressed and fixed to the vehicle by the extended edges 32 of the adapter profiles 3;

[0029] Step 3: Install the passenger seat 5 between the two transfer profiles 3;

[0030] Step 4: The glass of the screen 6 is installed in the second slot 33 of the adapter profile 3 and clamped to the armrest of the screen 6 by a clamping block; the fixing seat of the screen 6 passes through the through hole opened on the adapter profile 3 and is fixed to the vehicle door pillar 1;

[0031] Step 5: Finally, insert the inner side of the door pillar cover plate 4 into the first slot 31 of the adapter profile 3. In order to achieve a better plug-in effect, soft non-metallic materials such as rubber strips can be added to the plug-in interface to ensure a firm plug-in without abnormal noise. The other side is connected to the door seal through fasteners.

[0032] The present mounting structure is particularly suitable for projects with small body modules where the dimension L between the door pillar covers, typically installed on interior side walls, is less than the minimum passenger seat dimensions. The present interior side wall plug-in mounting structure effectively resolves this issue, increasing passenger seat space and enhancing passenger comfort.

[0033] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
