Specific embodiment
Below against attached drawing, by the description of the embodiment, making to a specific embodiment of the invention further details of
Explanation.
This seat of the present invention experimental testing station that jolts as shown in Figure 1, including bracket 1 is equipped with fixed peace on bracket 1
The mounting base 2 of seat 3 is filled, the kentledge 5 acted on seat 3 that can move up and down is equipped with above mounting base 2, which surveys
Test stand is additionally provided with the device of rotation driving of driving kentledge rotation.Seat of the present invention jolts experimental testing station, using on kentledge
Lower movement acts on seat 3, and simulation people sits on the seat, the load of vertical direction effect on the seat, device of rotation driving
Kentledge 5 is driven to rotate, simulation people's double swerve effect power on the seat, seat experimental testing station structure of jolting is simple,
It is easy to operate, it is on the seat by the effect of upper and lower and rotation direction kentledge 5, high to the accuracy in detection of seat.
In the present invention, the top of kentledge 5, which is equipped with, drives its vertically moving lift cylinders 4.It is set below kentledge 5
There is cushion block 9, cushion block 9 selects soft rubber material to be made, prevents plowing from seat surface.The flexible rod end of lift cylinders 4 passes through bearing
It is connected with shaft 10, kentledge 5 is connected to the lower end of shaft 10.Lift cylinders 4 drive 5 oscilaltion campaign of kentledge, shaft 10
Kentledge 5 is connected, drives kentledge 5 to rotate by device of rotation driving drive shaft 10.It when specific operation, can be according to setting
Sequence of motion controls the up and down motion and rotation of kentledge, to detect service condition of the seat 3 under turbulent conditions.
In the present invention, as shown in Fig. 2, kentledge 5 is equipped with hinged block 12, pin shaft passes through hinged on hinged block 12
Hole is rotatably connected in the lower end of shaft 10.Kentledge 5 and shaft 10 are rotatable hinged, can effectively avoid in experimentation and press
The case where carrying block movement Caton, guarantees smoothly experimentation.
In the present invention, as shown in figure 3, device of rotation driving includes the sector 6 in shaft 10, sector 6 and drive
7 engaged transmission of moving gear.Sector 6 can control the slewing area of kentledge 5, preferably within the scope of just to the left and right 50 degree of seat 3
Rotation, to simulate the normal scope of activities of passenger.Device of rotation driving further includes the motor 8 set on 1 side of bracket, motor
8 output shaft end connection driving gear 7.Rotation realize during, by motor 8 start rotate, driving gear 7 rotation drive with
Its sector 6 engaged rotates, so that kentledge 5 be driven to rotate in the slewing area of sector 6.
In the present invention, driving gear 7 and sector 6 to select has certain thickness, to guarantee in 4 moving range of lift cylinders
It is interior, drive gear and sector 6 to keep meshing state.
