Background technology
The ridge of vehicle interior, has very important impact according to character such as its positions to the safety of occupant, therefore must
The characteristic such as position of thing projecting inward to car must test and control." the internal ridge of passenger car " regulation thing projecting inward to car enters
Go definition, and propose its size range and other performance requirements.Before test scope refers mainly to front-row seats " H " point,
Crew module's internals (except side door) more than the upper and lower demarcation line of instrument board.Test process mainly includes determining impact zone method,
Determine region, and test point protrusion height, the force value that comes off, case hardness and material energy absorption etc. check.Therefore, respectively
The region carried out before item test determines extremely important, will directly determine which point will enter the scope of regulation detection.Seat " H "
Point refers to the friendship of the trunk representing the three-dimensional H point device of the human body theoretical rotating shaft relative to thigh and the longitudinally perpendicular plane of seat
Point, it is believed that " H " puts relative seat chair pad structure is fixing, and mobile with the regulation of seat.
Current existing pendulum test device comprises diameter 165mm rigidity head dummy and continuously adjustabe telescopic arm.But the rotation of this device
Gyration is fixed, and is connected with emission system, does not simply fail to be placed on and carries out static region on seat in car and determine, angle adjustable simultaneously
Scope is the most limited.

Detailed description of the invention
Below in conjunction with accompanying drawing illustrated embodiment, this utility model is further described.
The utility model proposes a kind of region and divide device, Fig. 1 is its structural representation, and Fig. 2 is that the structure of its part-structure is shown
It is intended to.This region divides device and includes rigid base 1, X direction guiding rail 2, Z-direction guide rail 3, motion bar 4, universal joint 5, expansion link 6
With Sphere Model 7.
This rigid base 1 is matrix pattern.X direction guiding rail 2 is installed in rigid base 1, and this X direction guiding rail 2 has two, all comprises X
To guide groove;Two X direction guiding rails 2 are parallel to each other to be spaced and arrange.Z-direction guide rail 3 has two, all comprises Z-direction guide groove;Two Z-direction guide rails
3 are parallel to each other is spaced setting.Two Z-direction guide rails 3 are connected to guide X of two X direction guiding rails 2 respectively in bottom by the first nut 10
In groove.Motion bar 4 is movably connected in Z-direction guide rail 3;Specifically, the two ends of motion bar 4 are each passed through the Z of two Z-direction guide rails 3
To guide groove, and it is connected in Z-direction guide rail 3 by the second nut 11 respectively.Therefore, motion bar 4 can be along Z-direction guide rail 3 in Z-direction
Upper movement;Simultaneously because Z-direction guide rail 3 is movably arranged in X direction guiding rail 2, therefore Z-direction guide rail 3 can be with motion bar 4 along X
Direction guiding rail 2 moves up at X.Wherein, X is to the direction of the plane for being parallel to rigid base 1, and Z-direction is for being perpendicular to rigid base 1
The direction of plane, Z-direction be also perpendicularly to X to.
Universal joint 5 is arranged at the point midway of motion bar 4.Expansion link 6 one end is connected on motion bar 4 by universal joint 5, another
The mode connecting ball head model 7 that end is threaded connection.This expansion link 6 is continuous and adjustable bar, including coaxial nested outer tube and interior
Pipe, and adjust inner tube stretch out the length of outer tube by the 3rd nut 12, thus regulate the length of whole expansion link 6 continuously.This reality
Execute in example, expansion link 6 spacing of the top of the Sphere Model 7 regulated and the hinge point of universal joint in the range of
736mm~840mm.
In the present embodiment, a diameter of 165mm of this Sphere Model 7.This Sphere Model 7 is made up of plastic material.
Additionally, be additionally provided with level indicator 8 and test desk 9 in rigid base 1, test desk 9 is regulation of longitudinal angle measuring table.
This level indicator 8 comprises bubble and rule, with by checking that by this rule the position of bubble judges that this region divides device and is
No it is in level.This test desk 9 is arranged on Z-direction guide rail 3, the seat fore-and-aft tilt during adjusting at seat
The accurate measurement of angle.
This region divides the main test instrunment during device detects as the internal ridge of vehicle, especially passenger car, for vehicle
The static division in the head impact region of internal ridge detection.During operation, place it on pilot set or seat,
Unclamp the first nut of Z-direction guide rail and the second nut of X direction guiding rail, motion bar carried out X and regulates to the displacement with Z-direction,
Until the X of the AnchorPoint of motion bar to put with the coordinate figure of Z-direction and " H " corresponding X to and the coordinate figure of Z-direction consistent.Adjust
Need the centre position keeping the bubble of level indicator to be in rule during joint, i.e. keep this region to divide device integral level.
After adjustment terminates, tightening the first nut and the second nut, now this region divides device and is in original state.
Use digital display angle instrument, measure now this region by test desk 9 and divide the longitudinal inclination of device, so that it may obtain seat
The longitudinal inclination of chair.This longitudinal inclination is adjusted to test angle value corresponding to vehicle, then every sub-region divides dress
The measurement result put is all to draw under consistent trystate, it is simple to the comparison of later stage side face result and analysis.
Unclamp the 3rd nut of expansion link, by the length of telescopic adjustment expansion link.Swinging, telescopic bar, observing Sphere Model can
The position of the projecting inward thing of car in contact, tightens the 3rd nut, and labelling contact point during contact check.In the method by the
The position of three nut adjustable telescopic rods, each contact point of labelling.After the contact point in front-seat member cabin is confirmed, connect from these
Contact removes the release region of laws and regulations requirement, remaining for test zone, test zone is depicted, to treat this region is entered
Row any reconnaissance checking.
This utility model can be arranged as the main auxiliary that car projecting inward analyte detection region divides, and assists testing crew according to riding
Ridge relevant laws and regulations within car have required that static head impingement region divides, and this head impact region i.e. laws and regulations requirement is carried out
The region that ridge height, case hardness, energy-absorbing material performance etc. check.During zoning, testing crew needs
Sphere Model of controlling well moves, rotates, and to judge the contact situation of car inner surface, thus plastic material reduces bulb mould
The quality of type, facilitates testing crew to control, improves test efficiency.Rigid base passes through expansion link by universal joint and Sphere Model
Connect on the same axis, thus hinge point can either be made to determine whether the position of rigid base meets seat " H " point coordinates
Value, it is also possible to make Sphere Model carry out stretching and rotating around " H " point coordinates position of seat longitudinal centre line position, have
Achieve to effect the division in thing projecting inward to car region to be detected.
