DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0024] In the description of the embodiments, unless otherwise clearly specified and limited, the terms "disposed", "connected" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or it can be connected through an intermediate medium, or it can be a communication between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0025] like Figure 1-2 As shown, the new fiberglass seat for rail vehicles in this embodiment includes an integrally formed fiberglass seat body 1 and a frame, the frame including two oppositely arranged cross bars 2, one end of each of the two cross bars 2 is vertically provided with a longitudinal bar 3, the connection between the two cross bars 2 and the longitudinal bar 3 is connected by a cross beam 4, and a plurality of bolt holes 5 are provided on the cross bars 2 and the cross beam 4, the base of the seat body 1 is clamped with a connecting hole 7 provided on the cross bar 2 by a buckle 6, and the backrest of the seat body 1 is connected to the longitudinal bar 3 by a plug-in assembly 8.

[0026] Both sides of the seat body 1 are provided with enclosures 9 integrally formed with the seat body 1 , and the enclosures 9 have a shielding effect. When the seat body 1 is fixed on the frame, the frame cannot be seen from the side, thereby improving the aesthetics of the seat.

[0027] The plug-in assembly 8 includes a U-shaped plate 81 and a plug-in plate 82. The two side walls of the U-shaped plate 81 are fixed to the two sides of the longitudinal rod 3 by bolts 83, and the front side wall of the U-shaped plate 81 and the front side of the longitudinal rod 3 form a plug-in space. The plug-in plate 82 is arranged in the plug-in space, and the top of the plug-in plate 82 is connected to the backrest of the seat body 1.

[0028] like Figure 3 As shown, the buckle 6 includes a connecting column 61, a plurality of elastic arms 62, a socket 63 and a threaded sleeve 64. The connecting column 61 is arranged at the bottom of the socket 63, the plurality of elastic arms 62 are inclined and spaced around the connecting column 61, and the threaded sleeve 64 is arranged at the top of the socket 63 and connected to the base of the seat body 1.

[0029] When the seat leaves the factory, the buckle 6 and the plug plate 82 are pre-installed on the seat body 1, and the U-shaped plate 81 is pre-installed on the frame; during on-site installation, align the plug plate 82 with the plug-in space on the longitudinal rod 3. At this time, the position of the buckle 6 also corresponds to the connecting hole 7. Then slowly move the seat body 1 downward to allow the plug plate 82 to completely enter the plug-in space. Finally, press the seat body 1 hard to allow the buckle 6 to fit into the connecting hole 7, thereby achieving the installation and fixation of the seat body 1 and the frame. The entire installation process does not require the aid of tools, which effectively improves the installation efficiency of the seat.

[0030] like Figure 4 As shown, the seat body 1 includes a transparent gel coat layer 11, a color layer 12, a transition layer 13 and a reinforcement layer 14 from the outside to the inside, and the transparent gel coat layer 11, the color layer 12, the transition layer 13 and the reinforcement layer 14 are bonded to each other by resin.

[0031] During production, firstly, unsaturated polyester resin is sprayed on the surface of the mold, and a transparent gel coat layer 11 is formed after drying and solidification; then a layer of colored surface felt is laid on the surface of the transparent gel coat layer 11, and the resin is rolled on to form a color layer 12. The colored surface felt can be made into different colors, textures or patterns according to needs to improve the aesthetics of the seat and meet personalized needs; then phenolic resin is sprayed on the surface of the color layer 12, and a transition layer 13 is formed after drying and solidification; finally, phenolic fiberglass of different thicknesses is pasted as needed to form a reinforcement layer 14, and demolding can be performed after it is completely dried.

[0032] The above is only a preferred embodiment of the utility model, and is not intended to limit the utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement; when the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the utility model.
