Description
Technical field
The utility model relates to automobile test field, relates in particular to a kind of calutron of irony preventing car door bounce-back.
Background technology
Along with the raising of modern social economy level, automobile pollution significantly increases, and has occupied the every aspect of people's life, bring more convenient with fast.But automotive performance also more and more receives the concern of user vehicle simultaneously.The automobile of a new research and development all needs to do front/rear door and opens and closes long duration test before listing, thereby guarantees that user there will not be the situations such as distortion, sinking, damage at the long-term exit door that uses.Orthodox car front/rear door opens and closes long duration test and checks with aerodynamic testing equipment, may there is following situation: under specific environment (as low temperature environment), between car door and doorframe, exist larger absorption affinity and testing equipment atmospheric pressure value deviation range larger, therefore the critical opening force value of car door is bigger than normal, when actual opening force value surpasses critical opening force value, car door momentum is often bigger than normal and cause car door to arrive at back to rebound after extreme position certain distance again.As excessive in the distance that rebounds, closing of the door push rod cannot contact with car door and can not complete closing of the door action.Such situation can produce two kinds of impacts: car door resilience belongs to the additional act in car door test, increases additional load can to thus some parts (as car door limiter), thereby make test findings distortion; As excessive in car door bounce-back distance, closing of the door push rod can not complete closing of the door action, and follow-up test action cannot be carried out, and causes thus passive the stopping of test.
Utility model content
In order to overcome arrangements for automotive doors, open and close the problems referred to above that exist in endurancing, the technical program provides a kind of calutron of irony preventing car door bounce-back.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
The utility model provides a kind of calutron of irony preventing car door bounce-back, and this calutron comprises:
For the power-supply device of working power is periodically provided;
Electromagnet assembly;
Fixed support;
Base, fixed support is fixed on base; Wherein
Electromagnet assembly comprises successively the fixed part that connects, connecting portion and for the operate portions of magnetic attraction is provided; Fixed part is removably connected on fixed support; One end of connecting portion is connected with fixed part, and the other end is connected with operate portions; The operative end surface of operate portions is towards irony car door, and operate portions is also electrically connected to power-supply device.
Alternatively, operate portions is truncated cone-shaped structure.
Alternatively, fixed support comprises the first fixed support and the second fixed support, the first support bracket fastened first end and the second support bracket fastened first end are fixed on base, first support bracket fastened the second end is dismountable to be connected on the second fixed support, and the first fixed support, the second fixed support and base form triangular structure.
Alternatively, the fixed part of electromagnet assembly and the second fixed support removably connect by bolt.
Alternatively, first support bracket fastened the second end is connected on the second fixed support by bolt is dismountable.
Alternatively, support bracket fastened material is aluminium section bar matter.
The beneficial effects of the utility model are:
In above-described embodiment of the present utility model, provide that operate portions on a kind of electromagnet assembly is electrically connected to the power-supply device that periodic duty is provided, the operative end surface of operate portions is towards the syndeton of car door, thereby can utilize electromagnetic force to make irony car door rest on its maximum opening position, avoid car door bounce-back.

Wherein in figure: 1, electromagnet assembly; 2, the first fixed support; 3, the second fixed support; 4, base; 5, irony car door.
Embodiment
For making the technical problems to be solved in the utility model, technical scheme and advantage clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
As one of the present utility model be embodiment, as shown in Figure 1 and Figure 4, calutron comprises: for the power-supply device of working power is periodically provided; Electromagnet assembly 1; Fixed support; Base 4, fixed support is fixed on base 4; Wherein electromagnet assembly 1 comprises successively the fixed part that connects, connecting portion and for the operate portions of magnetic attraction is provided; Fixed part is removably connected on fixed support; One end of connecting portion is connected with fixed part, and the other end is connected with operate portions; The operative end surface of operate portions is towards irony car door 5, and operate portions is also electrically connected to power-supply device.
In embodiment of the present utility model, the size of the cycle of power-supply device by the irony car door 5 of underproof vehicle determines, it is a predetermined value, periodically energising power-off, when testing, calutron of the present utility model does not all contact with car door, and when power-supply device is connected, operate portions is offset the bounce of irony car door 5 to make irony car door 5 stop at its maximum opening position by electromagnetic attraction; Irony car door 5 is before the action of closing the door, and power-supply device disconnects, and irony car door 5 is got back to its off-position closing under power effect subsequently.
