Embodiment
In order to make those skilled in the art person understand the utility model scheme better, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Please refer to Fig. 1, Fig. 2, Fig. 3, Fig. 1 provides by the utility model the vertical view of a kind of embodiment of top antenna mount pad; Fig. 2 is the A-A view of Fig. 1; Fig. 3 is the B-B view of Fig. 1.
In a kind of specific embodiment, the top antenna mount pad that the utility model provides is primarily of base 1 and top board 2 two large divisions composition.
Wherein, base 1 is in hollow box-structure, in square on cross section, its base plate 1-1 is relative to sidewall 1-2 inside indentation certain distance in a longitudinal direction, in the shape be inwardly recessed, top board 2 is positioned at base 1 top, is greater than the rectangle of base 1 cross section in size, and its periphery stretches out relative to base 1 and forms clamping edge.
Top board 2 inner top is fixed with astronomical cycle screw-jointing seat 3, this screw-jointing seat 3 be on width of the carbody direction transverse weld in the flat rectangle hollow section bar of top board 2 inner top, two screwed holes on each screw-jointing seat 3 are corresponding with the screwed hole on top board 2, and left and right is symmetrical on width of the carbody direction, for being fixed antenna by screw or bolt, for screw or bolt provide corresponding link position.
As shown in the figure, the top of top board 2 is also provided with the closed projection 4 of a circle circumference, it can be integral type structure with top board 2, also individually can process and then fit together, protruding 4 interior zones enclosed are top antenna installing zone, on vertical view, this top antenna installing zone is rectangular, and it is inner that the screwed hole on top board 2 is positioned at top antenna installing zone.
Due to top antenna 5 after mounting, its cable 6 needs to be introduced into vehicle body from roof, to set up electric power and communication connection, therefore, this top antenna mount pad is also provided with cable through hole 7, and structurally, cable through hole 7 is through base 1 and top board 2 longitudinally.
Particularly, cable through hole 7 is formed by the circular sleeve being fixed on chassis interior, and it is located at middle position car body fore-and-aft direction being partial to rear side.
For improving the heat-proof quality at astronomical cycle position further, can in the inner chamber of base filling with insulation material (not shown), such as blowing agent etc.; And, for improving the structural strength of base, the structures such as corresponding reinforcement can also be designed at chassis interior, so that under the prerequisite meeting loss of weight requirement, improving the car body strength at astronomical cycle position.
Although above-mentioned base 1 and top board 2 design rectangular, specifically do not limit to therewith, according to layout and the needs of roof installing space, other shapes such as rounded, semicircle, oval, triangle, trapezoidal, polygon can also be designed.
In addition, the form of screw-jointing seat 3 is also not limited to strip section, can also be the nut being welded on top board 2 inner top, or offers the contiguous block of screwed hole, etc., even can save screw-jointing seat, during installation, with nut from inside by bolt-locking.
For regular cable, especially beaming type cable, the through hole of cable shown in figure just can meet the cabling requirement of antenna substantially.But consider at some in particular cases; the cable of antenna may compare dispersion; to this; multiple cable through hole 7 can be designed; be respectively used to through diverse location, dissimilar antenna; the formation of cable through hole 7 also need not rely on sleeve completely; for the consideration simplified; sleeve can be saved; cable is directly introduced vehicle body through the through hole on the through hole on top board, chassis interior, base plate from top to bottom successively; but because sleeve can play a very good protection to the cable passed from its inside, be therefore ideal scheme.
Foregoing is only the preferred version of the utility model top antenna mount pad, is specifically not limited thereto, and can make pointed adjustment according to actual needs on this basis, thus obtain different execution modes.Because mode in the cards is more, just illustrate no longer one by one here.
Please refer to Fig. 4, Fig. 4 to be arranged on the structural representation of car body top for top antenna shown in Fig. 1 by mount pad shown in Fig. 1.
Except above-mentioned top antenna mount pad, the utility model also provides a kind of rail vehicle, comprises car body 8 and top antenna 5, and top antenna 5 is installed on car body 8 top by mount pad, and wherein, mount pad is above described top antenna mount pad.
As shown in the figure, the base 1 of top antenna mount pad embeds in the installing hole at car body 8 top, the clamping edge of top board 2 is supported in car body top, top antenna installing zone is fixed on by screw 9 (or bolt) in the bottom of top antenna 5, and be connected with car body top full weld, form one between its periphery and protruding 4 and enclose annular region, the inside filling with sealant 10 of annular region, the bottom thickness of top antenna 5 is greater than protruding 4, therefore, the top of fluid sealant 10 is inclined-plane, the cable 6 of top antenna 5 is introduced into vehicle body through cable through hole 7 from roof, to set up electric power and communication connection.
Because mount pad is hollow box body structure, astronomical cycle screw-jointing seat 3 is welded with in casing, while ensure that astronomical cycle intensity, reduce mount pad overall weight, meet the theory of motor train unit light-weight design, and mount pad is installed on motor train unit roof in the mode of sedimentation, reduces the setting height(from bottom) of top antenna 5, improve car body profile smoothness, meet the requirement of motor train unit airflow design.
In addition, mount pad installed surface is provided with border projection 4, beats fluid sealant 10 raising whole tightness energy further after top antenna 5 mount pad by being coated with.Can meet the demand of motor train unit to air-tightness and airflow design, the rail vehicle, particularly aircondition that are also applicable to the various roof configuration such as subway, intercity car antenna are arranged on the rail vehicle of vehicle roof.
Above rail vehicle provided by the utility model and top antenna mount pad thereof are described in detail.Apply specific case herein to set forth principle of the present utility model and execution mode, the explanation of above embodiment just understands core concept of the present utility model for helping.Should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model principle, can also carry out some improvement and modification to the utility model, these improve and modify and also fall in the protection range of the utility model claim.
