Description
Technical field
The utility model is related to automobile technical field, and in particular to a kind of roof cross beam.
Background technology
Vehicle frame is typically made up of longitudinal and cross beam, and crossbeam is not only used to ensure the torsional rigidity of vehicle frame and bears longitudinal load
Lotus, but also be the critical piece for supporting automobile, it is the vital part of automobile, if automobile-used crossbeam is by the external world
Friction is collided, it is easy to deformed upon, deformation will be broken to a certain extent, and car owner is typically all when roof cross beam hair
It can just discover after raw fracture, generation can cause the imbalance of vehicle structure compared with the roof cross beam after large deformation, seriously
Control power of the car owner for automobile is had influence on, there is very big potential safety hazard.
Utility model content
The purpose of this utility model is that providing one kind has more than fracture self-checking function roof cross beam, solution at least one
Individual technical problem.
The technical problem that the utility model is solved can be realized using following technical scheme：
With fracture self-checking function roof cross beam, including a roof cross beam, it is characterised in that set on the roof cross beam
Have at least two depressions, the depression and be fixed with strain gauge transducer；
The bottom of the depression is a plane, and the lower surface of the resistance strain gage of the strain gauge transducer is covered with bonding
Layer, the resistance strain gage is bonded on the plane by the adhesive layer；
The depth of the depression is not less than the thickness of the strain gauge transducer；
The roof cross beam is provided with wiring groove, the wiring groove is provided with wire along its length, and the wiring groove is passed through
The depression, the electrode wires of the strain gauge transducer connect the wire.
Strain gauge transducer is the sensors for measuring deformation, and strain gauge transducer includes resistance strain gage, electricity
The elements such as polar curve, this patent is not that the structure of strain gauge transducer is changed, but by the detection side of strain gauge transducer
Formula is optimized so that strain gauge transducer can be fixed on roof cross beam, and is not influenceing roof cross beam installation requirement
In the case of detected.
Provided with two strain gauge transducers, the measurement direction of two strain gauge transducers in one depression
Vertically.One is used to measure the deformation on roof cross beam length direction, and another is used to measure on roof cross beam width
Deformation, detection is more comprehensively.

Three depressions, the top of roof cross beam 1, lower section depression it is staggered.It is easy in the detection positive and negative regional of roof cross beam 1
Deformed state.The direction of this patent, when being arranged on reference to roof cross beam on automobile, relative to the direction of automobile.
The distance between two adjacent strain gauge transducers be less than roof cross beam pass through between distance
1/3rd.In general, the middle part of roof cross beam is easier to deform upon than two ends, it is easier to be broken, by strain-type
Sensor is arranged on the position for being more prone to deformation, and it is more accurate to monitor.
General principle of the present utility model and principal character and advantage of the present utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply illustrate principle of the present utility model, on the premise of the utility model spirit and scope are not departed from, the utility model is also
Various changes and modifications are had, these changes and improvements are both fallen within the range of claimed the utility model.The utility model
Claimed scope is by appended claims and its equivalent thereof.
