Description
Technical field
The utility model is related to a kind of auto parts and components, and in particular to a kind of automobile roof beam.
Background technology
In-car many parts are needed to be installed on automobile roof beam, and the ceiling of decoration function is provided with below top cover, horizontal
Beam is installed between top cover and ceiling.Existing vehicle body upper top cover crossbeam is generally steel construction, and weight is big, is unfavorable for automobile light weight
Change, unfavorable effective extension automobile course continuation mileage.Connection between existing crossbeam and top cover is is rigidly connected, noise and comfortableness
It is poor.Noise reduction and comfortableness always are the factor that must take into consideration in Automobile Design, and existing noise reduction method is often
To power assembly system or white body overall structure again improvement and design, but these modes all costs are high, or realization is difficult,
And ideal effect can not be reached.The excitation for being transmitted through coming at power assembly is easily received at the roof bow of automobile and occurs local shake
It is dynamic, produce noise and vibrations are delivered at passenger, influence comfortableness.
Utility model content
Technical problem to be solved in the utility model is that there is provided a kind of automobile top cover for above-mentioned the deficiencies in the prior art
Crossbeam, to realize that Shu Zhendong is small, adaptive is good, the big purpose of lightweight and structural strength.
The technical solution adopted in the utility model is：A kind of automobile roof beam, including cross-beam body, the cross-beam body
For hollow aluminium profile structure, cross-beam body is parallel to each other on the side bar at top cover two ends, the cross-beam body two ends and side
The medial surface laminating of beam, cross-beam body bottom two ends extension has a joint face being fixedly connected with side bar, the joint face include with
It is evenly distributed with the flange face of side bar bottom surface connection and the flange being connected with the lateral surface of side bar, the flange face some recessed
Expansion glue is equipped with groove, the groove.
Further preferably, expansion glue is provided between the cross-beam body two ends and the medial surface of side bar.
Further preferably, the section of the cross-beam body is semicircle, and centre is provided with integrally formed with cross-beam body
Semicircular cavities are separated into 2 energy-absorbing chambers by reinforcement, the reinforcement, and the energy-absorbing intracavitary is filled with sponge.
Further preferably, the energy-absorbing intracavitary is provided with the dividing plate being interspersed.
Further preferably, it is connected with spongy layer between the bottom of the adjacent beams body.
Further preferably, the side bar is hollow aluminium profile structure.
Crossbeam of the present utility model is hollow aluminium with top cover side bar, alleviates weight, and the two is by elastic connection, has
What is imitated reduces the vibrations for being delivered to in-car and noise, and filling sponge and bottom set spongy layer in the cavity of crossbeam, enter
One step reduces noise, improves vehicle comfort level；Reinforcement is equipped with crossbeam and energy-absorbing intracavitary is provided with dividing plate, can be effective
Raising vehicle body at the top of intensity, and with endergonic structure, vehicle body is indeformable when encountering weight or strong external impacts to be collapsed.
Brief description of the drawings

Fig. 2 is the schematic cross-section of the utility model middle cross beam body；
Fig. 3 is the structural representation of joint face in the utility model.
Illustrate：1- cross-beam bodies, 2- side bars, 3- flange, 4- reinforcements, 5- dividing plates, 6- flange faces, 7- expansion glues.
Embodiment
Below in conjunction with the accompanying drawings, the utility model is further described.
As shown in figure 1, a kind of automobile roof beam, including cross-beam body (1), cross-beam body (1) it is arranged in parallel
On the side bar (2) at top cover two ends, cross-beam body (1) and side bar (2) are all hollow aluminium profile structure, and aluminium profile structure passes through mould
Has extrusion molding, weight is small, structural strength is big, both collision and weight can take into account simultaneously.Cross-beam body (1) two ends and side bar
(2) medial surface laminating.Cross-beam body (1) bottom two ends extension has the joint face being fixedly connected with side bar (2), the connection bread
Include the flange face (6) being connected with side bar (2) bottom surface and the flange (3) being connected with the lateral surface of side bar (2), flange (3) and side
The lateral surface of beam (2) is welded to connect.It is evenly distributed with flange face (6) in some grooves, groove and is equipped with expansion glue (7), method
Blue face (6) by expansion glue (7) elastic connection, can effectively reduce the vibrations for being delivered to in-car and noise with side bar (2).
Expansion glue is provided between the medial surface of cross-beam body (1) two ends and side bar (2), further reduces and is delivered to car
Interior vibrations and noise.
Specifically, the section of cross-beam body (1) for semicircle, centre be provided with cross-beam body (1) it is integrally formed plus
Strengthening tendons (4), the intensity of increase cross-beam body (1).Semicircular cavities are divided into 2 energy-absorbing chambers, the filling of energy-absorbing intracavitary by reinforcement (4)
There is sponge, sponge has the function of sound insulation and noise reduction.Energy-absorbing intracavitary is provided with the dividing plate (5) that is interspersed, and dividing plate (5) is by energy-absorbing chamber
Space is divided into some triangles, increases the structural strength of cross-beam body, vehicle body is being encountered weight or strong external impacts
When indeformable collapse.
Spongy layer is connected between the bottom of adjacent beams body (1), noise transmission can be reduced to in-car, vehicle is improved
Comfort level.
Described above only to express preferred embodiment of the present utility model, it describes more specific and detailed, but not
Therefore the limitation to the utility model the scope of the claims can be interpreted as.It should be pointed out that for the ordinary skill people of this area
