Background

People need to adjust the front and back positions of the seat before driving, and the comfortable seat position is beneficial to improving the driving safety. The durability of the sliding of the automobile seat frame directly affects the safety of driving, so the durability of the sliding of the automobile seat frame needs to be tested. The existing testing device mainly carries out testing by directly pulling the seat through the pump, the stress condition of the seat when the seat is directly pulled by using the pump is greatly different from the stress condition when the seat is pushed by a human body, the human body mainly depends on the hip to press the base when pushing the seat, the waist exerts force to generate friction force between the hip and the seat, the exerting point of the human body is from the waist to the hip, the gravity of the human body is added, the seat receives the oblique force in the direction from the waist to the hip, the force application condition of the oblique force is roughly divided into three conditions, when the seat needs to be moved in a small amplitude, the waist of the human body is motionless at the moment, only the hip is moved, and the force application of the human body rotates by taking the waist as an axis at the moment; when the seat needs to move in a larger range, the whole seat moves along with the movement, so that the waist of a person also moves along with the movement, the waist and the hip form an inclination force, the inclination angle is unchanged, and the whole body moves along with the movement of the seat; when a larger movement is needed, the buttocks do not exert force, the back of a person exerts force, the force application direction is horizontal force, and the force application point is the backrest, so that the test of the test device for pulling the seat by using the pump is inaccurate, and some human body simulating seat test devices gradually appear.

Patent No. 201510933554 includes dummy buttocks, dummy back and rotary telescopic test mechanism, dummy buttocks and dummy back are fixed on the first fixing plate and the second fixing plate respectively, the first fixing plate and the second fixing plate are hinged with a hinge, the upper ends of the first fixing plate and the second fixing plate are connected and supported with a first basket bolt, the inclination angle of the dummy back can be adjusted by adjusting the first basket bolt, namely the trunk angle of the dummy, the rotary telescopic mechanism is composed of a vertical column, a cross bar, a cylinder, a force sensor, a fixed end and a Morse cone, the bottom end of the lower section of the vertical column is hinged with the second fixing plate, the second basket bolt is connected between the upper end of the lower section of the vertical column and the second fixing plate, the lower section and the upper section of the vertical column are connected together through the Morse cone, the cross bar is two sections, the two sections are connected with the Morse cone, one end of the cross bar is connected with the vertical column, the other end of the cross bar is connected with the cylinder vertically, the lower telescopic rod of the cylinder is connected with the force sensor, and the force sensor is connected with the fixed end. In the above patent, the angle between the hip and the backrest of the dummy is adjusted to simulate the application of force to the human body, but the above patent still cannot perfectly simulate the three scenes described above, and the point of contact between the hip and the base, and between the back and the backrest each time the human body applies force is not fixed, and is not in the middle of the seat each time, and there is a possibility of deviation, so the above device is still imperfect.

Therefore, a testing device is needed, which can simulate the actual scene of a human body, namely the force application scene of a person to the seat when the person moves to a smaller, larger and maximum extent, and can also simulate the random force application point to push the seat, namely the force application scene of the person pushing the seat when the person sits at a deviated position, so that the testing result is close to the actual use condition.

As shown in fig. 16, when it is needed to simulate a small movement, the lifting device is lowered to place the position of the rotating rod at the position of the waist of the human body, initially, the connecting rod and the rotating rod are on the same plane, i.e. the force application device is vertically downward, the control system provides random position information, the first sliding block and the second sliding block move the upper part of the force application device, the cross rod and the vertical rod move the lower end of the force application device, the force application device is near the middle part of the seat, then the vertical rod moves forwards or backwards, the second random device is not moved, at the same time, the telescopic end of the force application device extends to apply a force to the seat through the hip prosthesis device, the inclination angle of the force application device is larger as the moving distance of the vertical rod is farther, and the telescopic end of the force application device gradually extends to apply pressure to the seat, which completely simulates the situation that when the waist of the seat moves in a small movement, at the moment, the waist of the human body is not moved, only the buttocks move, at the moment, the force application of the human body is in a scene of rotating by taking the waist as the axis,

as shown in fig. 17, when a large-amplitude movement is required, on the basis of a small-amplitude movement scene, the force application device has a certain inclination angle, the sliding device still slides under the force application of the force application device, the angle of the force application device does not change at this time, the vertical rod and the first sliding block are controlled by the controller to perform horizontal movement at the same speed, namely, the rotating rod and the connecting rod are relatively static, the force application device and the seat are also relatively static, but the force application device performs horizontal displacement between the force application device and the fixed seat at this time, the whole seat moves along with the movement at this time, which also simulates a human waist moving along with the seat, an inclination force is formed between the waist and the hip at this time, the inclination angle is unchanged, and the human body moves along with the movement of the seat as a whole.

As shown in fig. 18, when needing to carry out the removal by a larger margin, on the basis of the great scope removal scene, the montant removes the lower extreme in spacing groove, and the horizontal pole then upwards risees gradually under the limiting displacement of connecting seat, force applying device is nearly horizontally state this moment, and the device becomes vertical state for the false buttock, the bottom surface of the device of false buttock is parallel with the back, force applying device extension flexible end gives a horizontal force to the back to having simulated this moment buttock not having developed a force, people's back is developed a force, force application direction this moment is the horizontal force, the point of application of force is the force application scene of back.
