High back timber compression strength, reduce deflection when top is pressurized, improve back timber and gusset mounting structure rigidity, reduce stress concentration,
Avoid ftractureing, back timber torsional rigidity is improved, so as to ensure the back timber component of occupant's living space.
A kind of back timber component of the present invention, including back timber body, the back timber body upper surface are provided with cover plate, the cover plate
Closing space is formed with the cross section of the back timber body.
A kind of back timber component of the present invention 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 and the back timber body.
Side-wall inner-plate is provided with the outside of the inner support, the side-wall inner-plate is detachably connected with the inner support.
Support arm is provided with the outside of the side-wall inner-plate, the support arm is detachably connected with the side-wall inner-plate.
The support arm is also detachably connected with the back timber body.
Gusset reinforcing plate is provided with the outside of the support arm, the gusset reinforcing plate is detachably connected with the support arm.
Side-wall outer-plate is provided with the outside of the gusset reinforcing plate, the side-wall outer-plate detachably connects with the gusset reinforcing plate
Connect.
A kind of back timber component of the present invention, including back timber body, the back timber body upper surface are provided with cover plate, the cover plate
Closing space is formed with the cross section of the back timber body.So, increase cover plate on back timber body, make the transversal of back timber body
Face forms closing space, and relatively existing U-shaped section, antitorque, the anti-pressure ability of back timber body are improved.One kind of the present invention
Back timber component, it is that can improve back timber compression strength and torsional rigidity relative to the advantages of prior art, when reducing top compression
Deflection, so as to ensure occupant's living space.

Embodiment
Fig. 2 below in conjunction with the accompanying drawings to Fig. 8 is described in further detail to a kind of back timber component of the present invention.
A kind of back timber component of the present invention, refer to Fig. 2-8, including back timber body 1, the upper surface of back timber body 1 is set
There is cover plate 2, the cross section of the cover plate 2 and the back timber body 1 forms closing space.So, lid is increased on back timber body 1
Plate 2, the cross section of back timber body 1 is set to form closing space, relatively existing U-shaped section, antitorque, the resistance to compression energy of back timber body 1
Power is improved.A kind of back timber component of the present invention, the compression strength of back timber body 1 and torsional rigidity can be improved, reduce top
Deflection during compression, so as to ensure occupant's living space.
A kind of back timber component of the present invention, refer to Fig. 2-8, can be with the basis of previously described technical scheme
It is：The cover plate 2 is welded on the back timber body 1.So, can be preferably by cover plate 2 and back timber by way of welding
Body 1 connects, and forms enclosed type space.Further preferred scheme is：The bottom of back timber body 1 is provided with inner support 3；It is described
Inner support 3 is 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 body
1 rigidity of structure, stress concentration is reduced, avoids ftractureing, and then improve the torsional rigidity of back timber body 1.Further preferred scheme
It is：The inner support 3 is detachably connected by bolt 8 and the back timber body 1.So, can be by bolt 8 by inner support 3
