Embodiment
See also Fig. 1, it is for opening the structural representation of durability test device in the car door that discloses according to the utility model one embodiment.Particularly, open durability test device in the car door and comprise seat fixed mount 1, cylinder 2, connecting rod 3 and swivel arm 4.Seat fixed mount 1 comprises two seat holders 11,12 that roughly become the F type, these two F type seat holders 11,12 are suitable for being clamped on the backrest of seat (not shown in figure 1) in the car, and are connected and fixed by a pedestal (not indicating among Fig. 1).Cylinder 2 comprises first end and the second end, and first end is that cylinder end 21, the second ends are tailpiece of the piston rod 22.Connecting rod 3 comprises first connecting rod 31 and the second connecting rod 32 of paired setting.Swivel arm 4 comprises the first swivel arm 41 and second swivel arm 42 of paired setting.The first swivel arm 41 comprises that drive end 411, pivot part 412, supported end 413, the second swivel arms 42 comprise drive end 421, pivot part 422, supported end 423.The first swivel arm 41, the second swivel arm 42 are V-structure roughly in Fig. 1, drive end 411,421 and supported end 413,423 lay respectively at the both ends of this V-structure, pivot part 412,422 supported end 413,423 and drive end 411,421 between the bending place of this V-structure.
The cylinder end 21 of cylinder 2 is fixed on the pedestal of this seat fixed mount 1.The first end of first connecting rod 31, the first end of second connecting rod 32 respectively by the first turning axle 51,52 and the tailpiece of the piston rod 22 of cylinder 2 pivotally connected.The second end of first connecting rod 31 is pivotally connected by the pivot part 412 of the second turning axle 61 and the first swivel arm 41, and the second end of second connecting rod 32 is pivotally connected by the pivot part 422 of another second turning axle 62 and the second swivel arm 42.The drive end 411 of the first swivel arm 41 is suitable for respectively being connected with two car doors about vehicle with the drive end 421 of the second swivel arm 42.For making the first swivel arm 41, the second swivel arm 42 move more steady reliable, the drive end 411,421 of the first swivel arm 41, the second swivel arm 42 is equipped with runner 81,82, and drive end 411,421 is connected with the rope (not shown in figure 1) with two car doors and is connected by runner 81,82.The supported end 413 of the first swivel arm 41 and the supported end of the second swivel arm 42 423 are pivotally connected with two F type seat holders 11,12 respectively by the 3rd turning axle 71,72.
The course of work of the present utility model is: be fixed on by seat fixed mount 1 on the backrest of two seats of vehicle opening durability test device in the car door, with release in the car door of vehicle, cylinder 2 actions, the tailpiece of the piston rod 22 of cylinder 2 is interior protruding from cylinder end 21 under the pressurized air effect, tailpiece of the piston rod 22 is by the first turning axle 51,52 promotion first connecting rods 31 and second connecting rod 32 are towards the direction motion that is separated from each other, first connecting rod 31 and second connecting rod 32 are by the second turning axle 61,62 drive respectively the first swivel arm 41 and the second swivel arm 42 towards the direction motion that is separated from each other, this moment, the first swivel arm 41 and the second swivel arm 42 were with the 3rd turning axle 71,72 be the axle center to inner rotary, promote left and right sides car door opening.After this, pressurized air in the cylinder 2 is discharged, the tailpiece of the piston rod 22 of cylinder 2 inwardly shrinks, tailpiece of the piston rod 22 is by the first turning axle 51,52 pulling first connecting rods 31 and second connecting rod 32 are towards the direction motion of closing up, first connecting rod 31 and second connecting rod 32 are by the second turning axle 61,62 drive the first swivel arms 41 and the second swivel arm 42 are towards the direction motion of closing up, this moment, the first swivel arm 41 and the second swivel arm 42 were with the 3rd turning axle 71,72 inwardly rotate for the axle center, lie in runner 81, the rope at 82 places spurs left and right sides closing of the door, thereby finishes the switch motion of a car door.So iterative cycles can realize opening in the car door endurancing.
The utility model embodiment assembles simply, easy operating, simulate opening in the actual car door fully, test consumable and number of cylinders have been reduced, greatly reduce experimentation cost, transmission by connecting rod 3,4 pairs of cylinder 2 power outputs of swivel arm reduces the power that directly acts on the vehicle door interior trim panel greatly, has reduced the infringement to vehicle door interior trim panel.
Be understandable that swivel arm 4 also can be done suitable malformation, is not limited to V-type; The cylinder end 21 of cylinder 2 and tailpiece of the piston rod 22 can exchange with the annexation of seat fixed mount 1, connecting link 3, can realize equally the door contact interrupter action.In addition, be understandable that the quantity of connecting rod and swivel arm is decided by the car door test quantity of practical application, for example is applied to the situation of bicycle gate test, then single connecting rod and swivel arm can only be set.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, although the utility model discloses as above with preferred embodiment, yet be not to limit the utility model, any those skilled in the art, within not breaking away from the technical solutions of the utility model scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solutions of the utility model, any simple modification that foundation technical spirit of the present utility model is done above embodiment, equivalent variations and modification all still belong in the scope of technical solutions of the utility model.
