On.Bolt arrangement is simple, cheap, and selection is bolted and not only can be easily installed and dismantle, while can reduce cost,
Improve connective stability.
A second object of the present invention is to provide a kind of run-through channel of vehicle vehicle, the run-through channel structure is more stable.
The run-through channel provided according to embodiments of the present invention, the run-through channel are equipped with the described in any item vehicles of above-described embodiment
Hook load-bearing composition 6, the hitch load-bearing composition 6 are fixed on the inside of the bottom end of the run-through channel.
Specifically, as schemed, the run-through channel further include: vestibule diaphragm composition, vestibule diaphragm composition include outer vestibule diaphragm composition 1 and interior
The inside of the outer vestibule diaphragm composition 1 is arranged in vestibule diaphragm composition 2, the interior vestibule diaphragm composition 2, and herein, the inside refers to described
The inner space that the profile of outer vestibule diaphragm composition 1 is impaled；The interior vestibule diaphragm composition 2 and outer vestibule diaphragm composition 1 can pass through several the
One connecting bracket 7 and the connection of several second connecting brackets 8, the setting of the first connecting bracket 7 and the second connecting bracket 8, so that interior
The connection that vestibule diaphragm composition 2 and outer vestibule diaphragm form 1 bracket is more convenient, while making the compressibility of entire vestibule diaphragm composition stronger,
Stability is higher.Meanwhile the interior vestibule diaphragm composition 2 is lower end two sides gradually intilted "door" type structure, "door" type structure
Open end be combined with transition composition 3, transition composition 3 and interior vestibule diaphragm composition 2 between form channel, in order to which passenger is in two section vehicles
It walks about between compartment, the outer vestibule diaphragm composition 1 is closed " mouth " type, and the support frame 61 of the hitch load-bearing composition 6 is installed on described
The bottom of " mouth " type makes entire hitch load-bearing composition 6 be located at the inside of outer vestibule diaphragm composition 1 and is located at the downside of transition composition 3.
The arrangement of this hitch pull-up run-through channel, can reduce the frictional force between run-through channel itself and car body, prevents run-through channel
Inordinate wear between inside and the transition apparatus of vehicle is caused danger, while this structure can reduce making an uproar for entire run-through channel
Sound, and the structure of run-through channel is more stable, convenient for the connection of hitch and the installation of vehicle run-through channel.
Herein, as shown, outer vestibule diaphragm composition 1 and interior vestibule diaphragm composition 2 are sewed by several U-shaped canopy cloth,
So several the first connecting bracket 7 and the second connecting bracket 8 is needed to connect interior vestibule diaphragm composition 2 and outer vestibule diaphragm composition 1, with
Guarantee the intensity of bonding strength and entire vestibule diaphragm composition between the two.In general, as shown in Figure 1, first connecting bracket 7
One end can connect to interior vestibule diaphragm composition 2 relatively upper side position, the other end can connect to outer vestibule diaphragm composition 1 upper end in
Side, one end of second connecting bracket 8 can connect to interior vestibule diaphragm composition 2 relatively lower end position, the other end can connect to
The lower end position of two inner sidewall of left and right of outer vestibule diaphragm composition 1 and close outer vestibule diaphragm composition 1.Herein, on along the longitudinal direction, connection
The distance between first connecting bracket of each adjacent two 7 between outer vestibule diaphragm composition 1 and interior vestibule diaphragm composition 2 and every adjacent two
The distance between a second connecting bracket 8 can be equal, so that the stress between interior vestibule diaphragm composition 2 and outer vestibule diaphragm composition 1 is equal
It is even.
