DETAILED DESCRIPTION

[0033] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0034] The carbon fiber streamlined curved rail vehicle interior panel of this embodiment is installed on the interior of the subway car body. Figures 1 to 6 As shown, the carbon fiber streamlined curved rail vehicle interior trim panel of this embodiment includes a frame 1, an interior trim panel body 2 and a fixed shock-absorbing strip 3.

[0035] The frame 1 includes aluminum alloy plates and aluminum alloy square tubes, and a plurality of aluminum alloy square tubes are assembled to form a "ladder" structure.

[0036] An aluminum alloy plate is provided at one end of the "ladder" type structure. The aluminum alloy plate is configured as a bent structure, and a bolt fixing interface 12 is provided on the bent structure to facilitate the installation of bolts.

[0037] Machined grooves 11 are provided on both sides of the frame 1, i.e., the two sides of the "ladder" structure. The machined grooves 11 are provided along the length direction of the frame 1 and are used to insert and fix the shock absorbing strips 3. More specifically, the machined grooves 11 are semi-enclosed, and the outer sides of the two sides of the frame 1 are open. By using the machined grooves 11 of this structure, the shock absorbing strips 3 are inserted so that the two adjacent interior panels are structurally fixed.

[0038] Among them, the interior trim panel main body 2 includes a panel body and a folding structure at one end of the panel body. The folding structure is matched with the aluminum alloy plate of the above-mentioned frame 1, and a bolt fixing interface 12 is also matched on the folding structure to facilitate the installation of bolts.

[0039] The material of the interior panel body 2 is carbon fiber prepreg. The interior panel body 2 is made of carbon fiber prepreg by compression molding (a certain amount of carbon fiber prepreg is added into a metal mold, heated and pressurized to solidify the mold, and the main advantages are high production efficiency, high product dimensional accuracy, and good repeatability). The overall appearance is clear from the inside of the car and has a strong three-dimensional sense.

[0040] The use of carbon fiber prepreg for the interior trim panel body 2 can effectively improve the strength and reliability of the interior trim panel on the one hand, and on the other hand, due to the low density of carbon fiber, effectively reduce the overall weight of the train, thereby achieving lightweighting of the train.

[0041] The interior trim panel body 2 is designed as a streamlined curved surface. Figure 4 , Figure 5 and Figure 6 It can be seen that the outer side surface of the interior trim panel body 2 is not a plane, and the interior trim panel body 2 as a whole protrudes outwards and presents a curved surface.

[0042] The interior panel body 2 can select different types of thicknesses based on different load requirements and operating conditions after a preliminary check of its structural strength through finite element simulation. The final thickness selection is verified through experiments. While meeting the performance requirements, different curved surface shapes can also be customized according to customer needs to achieve the minimum thickness to achieve the optimal strength design requirements and the appearance effect expected by the customer.

[0043] Preferably, the thickness of the interior trim panel body 2 is set to 2-4 mm.

[0044] The material of the fixed shock-absorbing strip 3 is plastic.

[0045] The disassembly and assembly process of the carbon fiber streamlined curved surface rail vehicle interior trim panel of this embodiment is as follows:

[0046] (1) The frame 1 and the interior panel body 2 are bonded together by high-strength structural adhesive to enhance the rigidity of the entire interior panel; the frame 1 is provided with plate machined grooves 11 (such as Figure 2 As shown, the difference is that in this step, the shock absorbing strip 12 has not yet been inserted into the timing processing groove 11).

[0047] (2) The outer side of the frame 1 is bonded with a nylon strap with adhesive backing, and the inner side bracket 4 of the vehicle body and the contact surface of the interior trim panel are also bonded with a nylon strap with adhesive backing. When the frame 1 and the inner side bracket 4 of the vehicle body are installed, the nylon straps of the two are in contact and fit together, so that the interior trim panel and the vehicle body can be fixed.

[0048] (3) Insert the shock absorbing strips 12 into the machined grooves 11 on both sides of the frame 1, as shown in FIG. Figure 7 and Figure 8 As shown, the frame 1 and the interior panel body 2 are fixed to the vehicle body as a whole (as shown in FIG. Figure 7 It also acts as a shock absorber when vehicles are running between adjacent wall panels.

[0049] (4) The upper end of the interior panel frame 1 is fixed by installing bolts in the bolt fixing interface 12 (such as Fig. 9 As shown), the interior panel is installed and the overall effect is shown in Figure 8 shown.

[0050] When disassembling for maintenance, Figure 8 The position shown, that is, the bolts of the bolt fixing interface 12 are removed, and then the fixed shock absorbing strip 3 is taken out, and the interior trim panel can be completely removed for maintenance. Whether it is installation or disassembly maintenance, it is equally convenient and quick.

[0051] The above description is only a preferred embodiment of the present invention and does not constitute a limitation on the protection scope of the present invention. Any modification, equivalent replacement and improvement made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
