[0042] Embodiment 1

[0043] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment provides a rail support for a bus, including a drawer frame 11 for mounting bus accessories, the drawer frame 11 can be mounted on the bus frame 3 on the roof, making full use of the free space in the bus roof, for example, the drawer frame 11 can be mounted in the air duct on the bus roof. The drawer frame 11 is a drawer-type push-pull structure to solve the problem of inconvenient maintenance.

[0044] Specifically, the drawer rack 11 includes two sliding components 111, an upper frame 112 and a lower frame 113. The upper frame 112 is provided with an L-shaped mounting member 1121 for mounting the drawer rack 11 on the coach frame 3. One side of the L-shaped mounting member 1121 is bolted to the upper frame 112, and the other side of the L-shaped mounting member 1121 is welded or bolted to the coach frame 3. When the L-shaped mounting member 1121 is bolted to the upper frame 112 and the coach frame 3, it is convenient to disassemble the damaged drawer rack 11 for replacement. The two sliding assemblies 111 are symmetrically arranged on the opposite side walls of the upper frame 112. The upper frame 112 and the lower frame 113 are slidably connected through the sliding assemblies 111. The upper frame 112 and the lower frame 113 are surrounded by an installation cabin 114 for installing bus accessories. The hatch of the installation cabin 114 faces the inner side wall of the bus. The bus accessories are installed on the lower frame 113, and the lower frame 113 can be pushed in and out from the hatch. Specifically, the sliding assembly 111 includes a slide 1111, a guide rail 1112 and a slider 1113. The slide 1111 is arranged on the side wall of the upper frame 112, and the guide rail 1112 is arranged on the slide The guide rail 1112 is embedded in the slide groove 11131 for the slide block 1113 to slide along the guide rail 1112, and the lower frame 113 is arranged on the slide block 1113. Then, the lower frame 113 can slide along the guide rail 1112 relative to the upper frame 112 with the slide block 1113 to realize a drawer-like push-pull action, that is, the lower frame 113 can be pushed into the installation cabin 114 from the hatch of the installation cabin 114 to store the bus accessories in the installation cabin 114, and the lower frame 113 can also be pulled out from the hatch to inspect and repair the bus accessories.

[0045] In this way, the drawer rack 11 for installing bus accessories is installed in the free space on the bus roof, which can improve the utilization rate of the bus installation space, and the drawer rack 11 is a drawer-type push-pull structure, which is convenient for personnel to inspect and repair the bus accessories.

[0046] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, in this embodiment, a plurality of drawer racks 11 are provided, and the plurality of drawer racks 11 are used to expand the space for installing the accessories of the bus, so as to improve the utilization rate of the free space of the bus. Two adjacent drawer racks 11 are connected by a U-shaped mounting member 12. Specifically, the two opposite sides of the U-shaped mounting member 12 are respectively connected with the two adjacent upper frames 112 by bolts, and the other side of the U-shaped mounting member 12 is welded or connected with the bus frame 3 by bolts. When the U-shaped mounting member 12 is connected with the upper frame 112 and the bus frame 3 by bolts, if a single drawer rack 11 is damaged, the damaged drawer rack 11 can be disassembled and replaced separately, without replacing the entire bus slide rail bracket 1, which is convenient for maintenance and saves maintenance costs. In addition, the U-shaped mounting member 12 is used to connect the two adjacent drawer racks 11, and also plays the effect of supporting the drawer rack 11, so that the plurality of drawer racks 11 are stably mounted on the bus frame 3, and the drawer rack 11 is prevented from shaking during driving.

[0047] like Figure 3 and Figure 4 As shown, in one embodiment, the guide rail 1112 is a rectangular guide rail, and the slide groove 11131 is a rectangular slide groove that matches the rectangular guide rail. The rectangular guide rail is embedded in the rectangular slide groove so that the slider 1113 can slide along the rectangular guide rail, and the rectangular guide rail and the rectangular slide groove are embedded to limit the slider 1113 in the vertical direction, thereby providing support force for the lower frame 113 set on the slider 1113, thereby improving the bearing capacity of the lower frame 113.

[0048] like Figure 5 As shown, in another embodiment, the guide rail 1112 is a wedge-shaped guide rail, and the slide groove 11131 is a wedge-shaped slide groove. The inclined wedge surface of the wedge-shaped guide rail fits with the inclined wedge surface of the wedge-shaped slide groove and has the same inclination angle, that is, the inclined wedge surface of the wedge-shaped guide rail cooperates with the inclined wedge surface of the wedge-shaped slide groove to achieve self-locking, so as to limit the slider 1113 in the vertical direction, so that the slider 1113 is not easy to fall off the wedge-shaped guide rail, further ensuring the stability of the sliding connection between the lower frame 113 and the upper frame 112, and at the same time improving the bearing capacity of the lower frame 113 set on the slider 1113, so as to ensure that the bus accessories can be firmly installed on the lower frame 113.

[0049] like Figure 3 and Figure 4 As shown, in this embodiment, a plurality of ventilation holes 1122 are provided on the top of the upper frame 112. The ventilation holes 1122 are used to promote air circulation in the installation compartment 114, dissipate heat for the bus accessories installed in the installation compartment 114, and extend the service life of the bus accessories.

[0050] like Figure 3 and Figure 4 As shown, in this embodiment, the ventilation hole 1122 can be a round hole, a square hole or a long hole according to actual design requirements.

[0051] like Figure 3 and Figure 4 As shown, in this embodiment, the lower frame 113 is symmetrically provided with two side ears 1131 on the hatch, which are against or separated from the slideway 1111. The side ears 1131 can limit the sliding of the lower frame 113, that is, the lower frame 113 cannot be pushed further into the installation cabin 114 until the side ears 1131 are against the slideway 1111.

[0052] like Figure 3 and Figure 4 As shown, in this embodiment, a plurality of weight-reducing holes 1123 are provided on two opposite side walls of the upper frame 112 to reduce the weight of the upper frame 112 and save production costs.

[0053] Embodiment 2

[0054] like Figure 6 and Figure 7 As shown, based on the same concept, this embodiment also provides a bus, including a slide rail bracket for a bus, which is the slide rail bracket 1 for a bus recorded in the first embodiment; and

[0055] The air duct body 2 is arranged on the roof of the bus, and the sliding rail bracket 1 for the bus is installed on the bus frame 3 and arranged in the air duct body 2 to make full use of the free space in the air duct body 2. The air duct body 2 is provided with a plurality of air outlets 21 for supplying air to the inside of the bus, and the air duct body 2 is provided with an outward-turning hatch 22 relative to the sliding rail bracket 1 for the bus. After the bus accessories are stored in the drawer rack 11, the hatch 22 is closed to ensure the beauty of the inside of the bus, and the bus accessories can be inspected and repaired by opening the hatch 22, which is simple and convenient to operate.

[0056] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
