[embodiment]
Easy understand, according to technical scheme of the present invention, do not changing under connotation of the present invention, one of ordinary skill in the art can propose multiple frame mode of the present invention.Therefore following embodiment and accompanying drawing are only illustrating technical scheme of the present invention, and should not be considered as of the present invention all or the restriction be considered as technical solution of the present invention or restriction.
Fig. 1 and Fig. 2 schematically shows the structural representation of testing table of the present invention, and wherein this testing table includes the first test portion for car door impulse test and the second test portion for cover or case cover.Be described in greater detail respectively below.
As shown in Figures 1 and 2, the first test portion for car door monitoring mainly includes framework, pulling twisted rope mechanism, drawing cable mechanism, elastic body and is used for monitoring the mechanism for monitoring of car door different conditions.
Framework builds preferably by aluminium section bar, for fixing or arrangement pulling twisted rope mechanism, drawing cable mechanism, elastic body and mechanism for monitoring.The height of framework, length and width can carry out layout according to the true form of car door, and this knows for those skilled in the art, therefore seldom repeats.
As shown in Figure 3 and Figure 4, pulling twisted rope mechanism includes electromagnetic brake 1, capstan winch and one-way clutch combination 2, whole line mechanism 3, planetary reducer 4, stepper motor 5 and steel wire twisted rope 6.Wherein, electromagnetic brake 1 is arranged on one end of capstan winch and one-way clutch combination 2 for carrying out control for brake to capstan winch and one-way clutch combination 2.Planetary reducer 4 is preferably integrated on the output shaft of stepper motor 5.The output shaft of stepper motor 5 is supported on capstan winch inside by bearing a and d, and its power is delivered on one-way clutch c via special-shaped key b, described one-way clutch is connected with described capstan winch by fixed screw e, thus makes stepper motor that capstan winch can be driven to carry out one-directional rotation.
Capstan winch is wound with steel wire twisted rope 6, and is fixed with whole line mechanism 3 near capstan winch place.One end of steel wire twisted rope 6 is connected on the edge of car door, for pulling open car door by whole line mechanism 3.Whole line mechanism 3 is except making the capstan winch take-up marshalling in capstan winch and one-way clutch combination, also to steel wire, there is certain pretightning force simultaneously, such can prevention occurs because closing the door and covering impact, and the phenomenon of the capstan winch winding displacement disorder that the effect of electromagnetic brake has time delay to cause.
As shown in Figure 2, drawing cable mechanism includes inhaul cable straight-line motor 11, cable retaining plate 10 and drag-line 14.Wherein drag-line 14 includes outside covering and can by steel wire tow line that inhaul cable straight-line motor 11 is twitched in covering, one end of drag-line 14 is fixed on door handle, for unblanking to car door, the other end is connected by the output shaft of cable retaining plate with inhaul cable straight-line motor 11.When inhaul cable straight-line motor 11 works, it can twitch the steel wire tow line in drag-line 14 within the specific limits, thus unlocks car door.
As shown in Figure 2, elastic body includes contact device, in order to apply the plate spring device of bounce to contact device, wherein contact device includes base 7 and L shape pivot arm 12, and wherein L shape pivot arm 12 can be rotated around base 7.Plate spring device includes the leaf spring 9 that can rotate around fixed pivot 50, is arranged on leaf spring 9 one end and the leaf spring of leaf spring can be driven to regulate motor 51.As shown in Figure 2, the vertical arm upper end of L shape pivot arm 12 is provided with the contact site contacted with car door, and its transverse arm lower end is provided with the pin portion 52 that can contact with leaf spring 9 other end.Wherein, different acting forces can be applied in pin portion 52 by different elastic deformations by leaf spring 9, thus the contact site of L shape pivot arm 12 is by pin portion 52 closed door.
Mechanism for monitoring includes position transducer 8,15 and angular-rate sensor 16.Wherein, sensor 8 is for detecting the compression degree of leaf spring 9, and sensor 15 is for detecting car door close to off-position, and sensor 16 is for detecting momentary angular speed during closing of the door.
The course of work for the first test portion of car door impulse test is as follows:
Before car door impulse test starts, regulate leaf spring to regulate motor 51 thus the bounce of setting leaf spring 9, car door is set to Normal Shutdown state.During test, first inhaul cable straight-line motor 11 works, and controls the rotation number of turns of inhaul cable straight-line motor thus makes it pull the steel wire in drag-line 14 to move a bit of air line distance, to meet unlock request.After unblanking, stepper motor 5 is started working, and one-way clutch normally works in the direction in which simultaneously, thus makes stepper motor 5 can tighten up twisted rope 6, thus car door opening.In the process of car door opening, car door touches the contact site of L shape pivot arm 12 and drives L shape pivot arm 12 to rotate around its base 7.Twisted rope 6 draws and receives to a certain degree, and the shank 52 of L shape pivot arm 12 touches leaf spring 9, thus shank 52 is oppressed leaf spring 9 and carried out elastic deformation, until after position transducer 8 detects activation signal, stop the rotation of stepper motor (5).Now, electromagnetic brake (1) is opened and keeps, thus avoids inertia impact.Whole take-up process terminates.
Before unwrapping wire operation, first stepper motor 5 rotates round about, and ensures the car door rotating speed that the rotating speed of stepper motor 5 is greater than the effect of leaf spring 9 car door and is formed.By this set, avoid twisted rope 6 to be forced to the inertial force applying to drive stepper motor 5 to reverse, thus cause the relatively large deviation of close the door actual speed and theoretical velocity.When stepper motor 5 rotates backward, due to the setting of one-way clutch, twisted rope 6 can not be driven by it and rotate, and that is, stepper motor 5 is in idling conditions.
During unwrapping wire, electromagnetic brake 1 power-off discharges, and under the effect of the elastic force of leaf spring, car door does and accelerates to rotate until depart from leaf spring 9, and the speed of its tail gate declines gradually.Stepper motor 5 also enters underdrive and finally enters into the default velocity of rotation corresponding to closing of the door impact velocity after accelerating rotation.If before closing of the door, find that car door speed exceeds regulation rotating speed, then stepper motor 5 is limited its speed by twisted rope 6.As shown in Figure 5.
When car door is close to terminal, sensor 15 detects signal, and now electromagnetic brake 1 works after a small time delay, thus tension twisted rope 6.Wherein, the action time of detent 1 puts should with car door collision moment be consistent as far as possible, and this realizes by test of many times fine setting.During closing of the door, angular-rate sensor 16 records the angular velocity of car door, thus determines car door velocity of rotation and collision impact size.
Easy understand, the first test portion of the present invention by regulating motor 51 again to regulate to leaf spring, can be tested when different bounce, or does not regulate leaf spring to regulate motor 51, repeatedly tests when identical bounce.
As shown in Figure 5, wherein some release time of 101 expression electromagnetic brakes 1, as mentioned above, stepper motor rotating speed 201 is higher than car door rotating speed 301 this moment, enters moderating process thereafter.When car door rotating speed 301 is greater than stepper motor rotating speed 201, stepper motor 5 limits its rotating speed that transfinites.In the small time delay after the signal time point 401 sensor 15 being detected, namely in Fig. 5 shown in 501, the car door detent 1 simultaneously that collides is started working, thus car door speed drops sharply to 0.
Similarly, the second test portion of the present invention is used for carrying out impact test to cover or case cover.Wherein, the second test portion includes another pulling twisted rope mechanism be arranged on framework, ejection mechanism and another testing agency.
Wherein the principle of work of another pulling twisted rope mechanism is substantially identical with aforementioned with structure, therefore seldom repeats.
Ejection structure is installed within the barrel by volute spring, and extension rod Compress Spring, forms pretightning force, to complete ejecting function; The size of pretightning force can regulate motor 18 to regulate to realize by launching.One end of projectile 19 contacts with cover or case cover, and the other end contacts with Compress Spring.Ejection force is produced by the release of Compress Spring.The object that ejection mechanism is arranged is to solve, and occurs because gravity can not reach the situation of closing lid speed; Close than the front and rear covers gravity if any hydraulic mandril device and often can not produce enough closedown impact quick-actions.
Another testing agency comprises the angular-rate sensor for detecting cover or case cover turn-off transient.
The course of work of the second test portion is substantially identical with the course of work of the first test portion.Therefore seldom repeat.
