Description
Technical field
The invention belongs to vehicle accessory field, buttress brace under especially a kind of preceding floor.
Background technology
The main function of automotive floor panel crossbeam is support and stress, so crossbeam needs enough rigidity and intensity
To ensure the torsion of vehicle body and mode, current rear floor crossmember is configured without rational reinforcing plate.
Widely available with automobile, automobile especially car has become the important component of the modern life,
It directly affects our impression and life.Meanwhile as people constantly deepen to the understanding of automobile, he
To select automobile requirement also can more and more higher, automotive performance as customer selection automobile important indicator
One of.And body performance embodies that its powerful status is more and more obvious in automotive performance, the rigidity of vehicle body,
Mode directly affects the comfortableness of interior of body occupant, be to determine one of precondition of comfortableness of occupant；
The factor of the collision safety emphasis examination of automobile is whether the rigidity, structure design, welding performance of vehicle body reach
It is required that outstanding vehicle passive security performance protects in-car member well.Complete vehicle weight is to determine vehicle again
Dynamic economicses and chassis braking, the key index of handling stability energy.
According to retrieval, patent document related to the application as follows is found, specific disclosure is as follows：
Patent document CN103770847A discloses longeron I under a kind of vehicle body front floor board reinforcement structure, including preceding floor,
Longeron II under preceding floor, longeron on floor, wherein, under the preceding floor front end of longeron I be welded to front apron and
Preceding floor, rear end are welded to preceding floor close to middle passage side, are connected with middle passage；Longeron under the preceding floor
II front end is connected and is welded on preceding floor with longeron I under the preceding floor, and rear end is connected with body sill.
Patent document CN 203460931U disclose reinforcing plate in a kind of automobile rear floor middle cross beam, including fix one
The left back floor middle baffle plate of body, it is right after floor middle baffle plate, described left back floor middle baffle plate,
Floor middle baffle plate is respectively provided with bending part, described left back floor middle baffle plate and horizontal stroke in floor behind the right side behind the right side
Funnel-form is shaped as when beam baffle plate is bonded, floor middle is kept off behind described left back floor middle baffle plate, the right side
Plate both ends have mounting hole.
Above-mentioned patent and the application difference are larger, do not influence the creativeness and novelty of the application.
The content of the invention
It is an object of the invention in place of overcome the deficiencies in the prior art, there is provided a kind of simple in construction, install convenient
Preceding floor lower-left buttress brace.
The technical proposal for solving the technical problem of the invention is：
A kind of preceding floor lower-left buttress brace, including longeron under longeron and preceding floor on floor, indulge under the preceding floor
Beam is vertically mounted on the front portion of longeron on floor, and longeron is a bar-shaped trough on the floor, and system is spaced on bottom land
There are multiple mounting bar holes, be formed with a bayonet socket in the cell body side wall of bar groove, longeron is one end open under the preceding floor
Cell body, the end sidewalls of cell body one end are sloped sidewall, and the cell body other end sets for opening corresponding to sloped sidewall
Put, the open end of wall and bottom land is formed with opposite outside opened type card at left and right sides of cell body, and card is fitted to
On floor in the bayonet socket of longeron.
Moreover, the cell body open side of longeron and the open side of longeron under preceding floor are towards identical on the floor.
The present invention be a little with good effect：
The present invention provides under a kind of preceding floor on buttress brace, including floor longeron under longeron and preceding floor, before described
Longeron is vertically mounted on the front portion of longeron on floor under floor, using the structure of setting-in, by under preceding floor
The clamp of longeron end is the cumbersome connection procedure that avoids being connected by screw bolts, simple on the floor in longeron
It is convenient.
The present invention is simple in construction, is easily installed manufacture.
Brief description of the drawings
Fig. 1 is the stereogram of the present invention；
Fig. 2 is Fig. 1 figure for looking up direction.
Embodiment
Below in conjunction with the accompanying drawings and the invention will be further described by specific embodiment, and following examples are simply retouched
The property stated, be not limited, it is impossible to limit protection scope of the present invention with this.
A kind of preceding floor lower-left buttress brace, including longeron 3 under longeron 2 and preceding floor on floor, under the preceding floor
Longeron is vertically mounted on the front portion of longeron on floor, using the structure of setting-in, passes through longeron end under preceding floor
The clamp in portion is the cumbersome connection procedure that avoids being connected by screw bolts, simple and convenient on the floor in longeron.
Longeron is a bar-shaped trough 2 on the floor, and interval is formed with multiple mounting bar holes 1 and 4 on bottom land, is used for
Installed with vehicle chassis, a bayonet socket is formed with the cell body side wall of bar groove, for being embedded in longeron under preceding floor.
Longeron is the short cell body of one end open under the preceding floor, and the end sidewalls of cell body one end are sloped sidewall 5,
The cell body other end corresponding to sloped sidewall is set for opening, and the open end of wall and bottom land is formed with left and right sides of cell body
Opposite outside opened type card 6, card is in the bayonet socket of longeron on floor, the groove of longeron wherein on floor
The open side of body open side and longeron under preceding floor is towards identical.
The length of longeron is 4-5 times of longeron under preceding floor on the floor.
One embodiment of the application is described in detail above, but the content be only the present embodiment compared with
Good embodiment, it is impossible to be considered as the practical range for limiting the application, it is all done according to the application scope it is equal
