In order to solve the above-mentioned technical problem, a kind of automatic driving vehicle attitude-simulating device provided by the utility model,
It is characterized by comprising bearing bases, carrying platform；
It has been vertically arranged elevating control screw rod on the bearing base, and has been equipped on bearing base for driving elevating control
The load of screw rod rotation controls motor, and the output shaft that load controls motor connects elevating control screw rod, carrying by transmission parts
Pedestal is equipped with the adjustable shelf that can be slid vertically, and adjustable shelf is connect with elevating control wire rod thread；
Gesture stability electric cylinders there are two being set on the adjustable shelf, and the vertical cloth of output shaft of two gesture stability electric cylinders
If being equipped with the load sensor for detecting load at the top of the output shaft of two gesture stability electric cylinders；
The universal joint there are three laying triangular in shape is set on the carrying platform, one of universal joint connection is lived
The top of moving frame, another two universal joint are separately connected the load sensor at the top of the output shaft of two gesture stability electric cylinders.
Automatic driving vehicle attitude-simulating device provided by the utility model passes through matching for adjustable shelf and elevating control screw rod
It closes and the control of two gesture stability electric cylinders is, it can be achieved that load simulated, the inclination of vehicle are simulated, energy simulation test vehicle is appointed
The meaning angle operating condition toppling, overturn, simulating vehicle is in jolting on slope road or muddy road or when turning under different speeds
Vehicle turnover state, can influence with simulating vehicle under unbalance loading, to the different power of each wheel；Be able to achieve all-terrain baby,
Whole scene, all standing abundant test, so as to automatic driving vehicle provide test safety estimate.

Specific embodiment
The embodiments of the present invention are described in further detail below in conjunction with Detailed description of the invention, but the present embodiment and are not had to
In limitation the utility model, all similar structures and its similar variation using the utility model should all be included in the utility model
Protection scope, the pause mark in the utility model indicates the relationship of sum.
As shown in Figure 1-Figure 3, a kind of automatic driving vehicle attitude-simulating device provided by the utility model embodiment,
It is characterized in that: including bearing base 3, carrying platform 1；
It has been vertically arranged elevating control screw rod 4 on the bearing base 3, and has been equipped on bearing base 3 for driving lifting
It controls the load that screw rod 4 rotates and controls motor 5, the output shaft that load controls motor 5 connects elevating control silk by transmission parts 6
Bar 4, bearing base 3 is equipped with the adjustable shelf 2 that can be slid vertically, and the upright guide rail slid vertically for guiding adjustable shelf 2, living
Moving frame 2 is threadedly coupled with elevating control screw rod 4；
Gesture stability electric cylinders 7 there are two being set on the adjustable shelf 2, and the vertical cloth of output shaft of two gesture stability electric cylinders
If being equipped with the load sensor 8 for detecting load at the top of the output shaft of two gesture stability electric cylinders；
Set on the carrying platform 1 in the universal joint 9(figure there are three laying triangular in shape and only show 2), it is therein
One universal joint 9 is the first universal joint, and another two universal joint 9 is the second universal joint, and the connection of the first universal joint 9 is lived
The top of moving frame 2, two the second universal joints 9 are separately connected the load sensing at the top of the output shaft of two gesture stability electric cylinders 7
Device 8.
In the utility model embodiment, the gesture stability electric cylinders (as shown in Figure 3) are the prior art, and electric cylinders are a kind of incite somebody to action
