Detailed description of the invention
The core of the present invention is to provide a kind of enging cabin, improves automotive engine compartment longitudinal beam and horizontal stroke
The bonding strength of beam, to slow down teeter.Another core of the present invention is to provide one and includes
The automobile of above-mentioned enging cabin.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, to the technical side in the embodiment of the present invention
Case is clearly and completely described, it is clear that described embodiment is only the present invention one
Divide embodiment rather than whole embodiments.Based on the embodiment in the present invention, this area is general
The every other embodiment that logical technical staff is obtained under not making creative work premise,
Broadly fall into the scope of protection of the invention.
Refer to shown in Fig. 1-Fig. 6, embodiments provide a kind of enging cabin, including
Longeron 1 and the front wall cross member 2 being connected with longeron 1, it also includes longitudinal beam connected 1 and antetheca
The bracing piece 3 of plate crossbeam 2, and this bracing piece 3, longeron 1 and front wall cross member 2 triangularity
Arrange.Longeron 1 can be improved by longeron 1 and front wall cross member 2 being connected by bracing piece 3
The stability connected with front wall cross member 2, when slowing down Vehicular vibration, front wall cross member 2 passes to
The teeter of longeron 1, thus improve the comfortableness of whole automobile, the most also can reduce
Destruction to automobile.
In specific embodiment, above-mentioned bracing piece 3 is set to L-type plate, to improve reinforcement
The intensity of bar 3 self, in practice, this bracing piece 3 can be the bending of single plate and
Become, it is possible to be that two plates weld or screw is formed by connecting.Can be steel for this bracing piece 3
Rod, steel pipe or alloy bar can also be even the plate of nonmetallic materials, such as carbon fiber board.
Bracing piece 3 disclosed herein specifically includes: inner panel 32 and outside plate 31, i.e. by two
Individual plate is formed by connecting, and specifically, this outside plate 31 is L-type plate, and the two of inner panel 32 sides
Plate is connected with two plate-side plate weldings of outside plate 31 respectively, with outside plate 31 at the drift angle of inner panel 32
Drift angle at formed triangle, i.e. this inner panel 32 is L-type plate, but the drift angle of this L-type plate
For right angle chamfering, when after the side plate of inner panel 32 with the plate-side plate welding of outside plate 31, inner panel 32 straight
At the chamfering of angle, the right angle with inner panel 32 forms triangle, so that the drift angle of whole bracing piece 3 exists
Can have certain deformation buffer during by external world's collision, thus absorb certain collision energy.
The quality of the automobile applying this enging cabin is can further improve by above-mentioned setting.
In preferred embodiment, the angle at the drift angle of above-mentioned outside plate 31 is 60 °-120 °,
And outside plate 31 for two length of triangle of being formed with inner panel 32 no more than 10mm.
The chamfer dimesion of bending angle and inner panel 32 by limiting outside plate 31 can ensure whole bracing piece
The intensity of 3 the most also can absorb the energy of collision within the specific limits, slows down rushing longeron 1
Hit.In practice, operator can be according to the different L-type knots setting this outside plate 31 when needing
Corner dimension at the drift angle of structure, and the size of the triangle of outside plate 31 and inner panel 32 formation,
To reach increase the purpose of intensity or increase the purpose of absorption collision energy.
In further embodiment, above-mentioned inner panel 32 has lightening hole 321, whole to reduce
The weight of bracing piece 3, thus reduce bracing piece 3 to longeron 1 and the torsion of front wall cross member 2.
Specifically, can be circular hole or bar hole for lightening hole 321.Ensure that inner panel 32
On the premise of requirement of strength, shape and number for lightening hole 321 can be according to different needs
It is set, and all in protection domain.
In order to improve the intensity of bracing piece 3 further, outside plate 31 disclosed herein away from
The surface configuration of inner panel 32 has a reinforcement 311, and by this reinforcement 311 along the length of outside plate 31
This outside plate 31 is run through in degree direction.Specifically, this reinforcement 311 is for being arranged on outside plate 31 surface
Projection, additionally, this reinforcement 311 can be also that to be arranged on the intensity on outside plate 31 surface bigger
Rod member.Position for reinforcement 311 is preferably provided on the side plate of outside plate 31, can be according to by force
The needs of degree arrange a reinforcement 311 on each side plate.
In further embodiment, set at this outside plate 31 drift angle away from the surface of inner panel 32
It is equipped with and can be bent deformation by collision and fractureed concave bar.Specifically, this concave bar that fractures is at bracing piece
3 when being impacted, can be by bending to the direction of inner panel 32 and absorbing at outside plate 31 drift angle
The energy of collision, thus the impact that buffering is to longeron 1, improve the life-span of enging cabin.
On the basis of technique scheme, disclosed herein a kind of bracing piece 3 and longeron
1 and the connected mode of front wall cross member 2, specifically, one end of bracing piece 3 has can be with
The first flange that longeron 1 is fitted and connected, and the other end has and can fit with front wall cross member 2
The second flange connected.The application is fitted and connected with longeron 1 by the first flange, can improve
Bracing piece 3 and the connective stability of longeron 1, in like manner the second flange is fitted with front wall cross member 2
Connect, the stability that bracing piece 3 is connected with front wall cross member 2 can be improved.Specifically, can adopt
It is connected with.Owing to bracing piece 3 is L-type structure, therefore, the first flange is also tied for L-type
Structure, therefore, all has at least one and bolt mate with threaded holes on each side；Second flange
Also it is L-type structure, and on a side plate, has two screwed holes, another side has one
Screwed hole.Mode stable connection with bolts, and low cost.
In practice, there are in enging cabin two longerons 1, the most left longeron and right vertical beam, because of
This, corresponding also has two bracing pieces 3, and both are symmetrical about the vertical line of front wall cross member 2
Arrange, but be set to asymmetric structure also dependent on being actually needed of enging cabin, but setting
It has to be ensured that bracing piece 3, longeron 1 and the triangular relationship of front wall cross member 2 three in meter.
The peace defining bracing piece 3 and front wall cross member 2 of enging cabin disclosed herein
The installation site of holding position and bracing piece 3 and longeron 1, specifically, above-mentioned bracing piece 3 exists
The distance that mount point on front wall cross member 2 is connected a little to front wall cross member 2 with longeron 1 is more than
150mm, and the mount point that bracing piece 3 is on longeron 1 is to front wall cross member 2 and longeron 1 phase
Even the distance of point is more than 150mm, and the angle of bracing piece 3 and longeron 1 is 35 °-55 °,
Bracing piece 3 is not more than 30 ° with the angle of front wall cross member 2.It is further ensured that by above-mentioned
The connective stability of bracing piece 3 and front wall cross member 2 and bracing piece 3 and longeron 1.
Specifically, bracing piece 3, by plate stamping, is welded, and treats that body in white assembly has welded
Cheng Hou, is bolted on longeron 1 and front wall cross member 2, and tighting a bolt i.e. to complete adds
The assembling of strong bar 3.This bracing piece 3 simple in construction, assembling is quick, and its cross section cavity can be
Square, circular or other shapes.
The invention also discloses a kind of automobile, it includes enging cabin, wherein, and this enging cabin
Enging cabin disclosed in above-described embodiment, therefore, the automobile with this enging cabin also has
Above-mentioned all technical schemes, this is no longer going to repeat them.
Described above to the disclosed embodiments, makes those skilled in the art be capable of or makes
