A kind of back timber component of the present utility model, including back timber body, the back timber body upper surface is provided with cover plate, described
Cover plate forms closing space with the cross section of the back timber body.
A kind of back timber component of the present utility model can also be：
The cover plate is welded on the back timber body.
The back timber body lower part is provided with inner support；The inner support is detachably connected with the back timber body.
The inner support is detachably connected by bolt with the back timber body.
The inner support outside is provided with side-wall inner-plate, and the side-wall inner-plate is detachably connected with the inner support.
The side-wall inner-plate outside is provided with support arm, and the support arm is detachably connected with the side-wall inner-plate.
The support arm is also detachably connected with the back timber body.
The support arm outside is provided with gusset reinforcing plate, and the gusset reinforcing plate is detachably connected with the support arm.
The gusset reinforcing plate outside is provided with side-wall outer-plate, and the side-wall outer-plate detachably connects with the gusset reinforcing plate
Connect.
A kind of back timber component of the present utility model, including back timber body, the back timber body upper surface is provided with cover plate, described
Cover plate forms closing space with the cross section of the back timber body.So, increase cover plate on back timber body, make back timber body
Cross section formation closing space, relatively existing U-shaped section, antitorque, the anti-pressure ability of back timber body are improved.This practicality is new
A kind of back timber component of type, the advantage relative to prior art is can to improve back timber compression strength and torsional rigidity, reduces top
Deflection when portion is pressurized, so as to ensure occupant's living space.

Specific embodiment
Fig. 2 to Fig. 8 below in conjunction with the accompanying drawings is described in further detail to a kind of back timber component of the present utility model.
A kind of back timber component of the present utility model, refer to Fig. 2-8, including back timber body 1, the upper table of back timber body 1
Face is provided with cover plate 2, and the cover plate 2 forms closing space with the cross section of the back timber body 1.So, increase on back timber body 1
Add a cover plate 2, make back timber body 1 cross section formed closing space, relatively existing U-shaped section, back timber body 1 it is antitorque, anti-
Pressure energy power is improved.A kind of back timber component of the present utility model, can improve the compression strength of back timber body 1 and torsional rigidity,
Reduce deflection when top is pressurized, so as to ensure occupant's living space.
A kind of back timber component of the present utility model, refer to Fig. 2-8, may be used also on the basis of previously described technical scheme
To be：The cover plate 2 is welded on the back timber body 1.So, can preferably by cover plate 2 and top by way of welding
Beam body 1 is connected, and forms enclosed type space.Further preferred scheme is：The bottom of back timber body 1 is provided with inner support 3；Institute
Inner support 3 is stated to be detachably connected with the back timber body 1.So, inner support 3 is set in the bottom of back timber body 1, improves back timber sheet
The rigidity of structure of body 1, reduces stress concentration, it is to avoid cracking, and then improves the torsional rigidity of back timber body 1.Further preferred side
Case is：The inner support 3 is detachably connected by bolt 8 with the back timber body 1.So, can be by bolt 8 by inner support
3 and back timber body 1 fix be detachably connected, make installation more flexible and convenient.Can also be：The outside of the inner support 3
Side-wall inner-plate 6 is provided with, the side-wall inner-plate 6 is detachably connected with the inner support 3.So, back timber body is made by inner support 3
1 greatly improves with the mounting structure rigidity of gusset.Further preferred scheme is：The outside of the side-wall inner-plate 6 is provided with outer branch
