The invention is described in detail below with reference to the drawings and specific embodiments, it is to be noted that in the drawings or description, similar or identical parts are provided with the same reference numerals, and implementations not shown or described in the drawings are known to those of ordinary skill in the art. In addition, directional terms, such as "upper", "lower", "top", "bottom", "left", "right", "front", "rear", and the like, used in the embodiments are only directions referring to the drawings, and are not intended to limit the scope of the present invention.

Example one

As shown in fig. 1 to 5, the present embodiment provides a stopper which is mainly applied to a door-grip-less vehicle door that opens by electromagnetic urging force as indicated in the background art. The limiter comprises a limiting arm 1, a limiting box 2, two elastic rubber blocks 3, a controller 4 and two electromagnets 5. Wherein, spacing arm 1 runs through spacing box 2 to spacing arm 1 can be along the length direction of spacing arm 1, moves relative spacing box 2. One end of the limiting arm 1 is hinged on the side wall 14 of the vehicle, and the limiting box 2 is arranged on the inner plate 15 of the vehicle door. Two elastic rubber blocks 3 are installed in the limiting box 2 and respectively extrude the two sides of the limiting arm 1 to provide limiting force for the limiting arm 1, so that the limiting effect on the vehicle door is realized. It should be noted that the working principle of the elastic rubber block 3 and the limiting arm 1 in this embodiment is the same as the working principle of the rubber spring type limiter in the prior art, and therefore, how the elastic rubber block 3 provides the limiting force for the limiting arm 1 is not described again in this embodiment.

Two electro-magnets 5 symmetry sets up, and two electro-magnets 5 all are fixed with connecting rod 6 in the one side that deviates from each other, and connecting rod 6 keeps away from in electro-magnet 5's one end extends to spacing box 2 to it is fixed with one side that one of them elastic rubber piece 3 deviates from spacing arm 1. Namely, the two electromagnets 5 are respectively connected with the elastic rubber block 3 through the connecting rods 6. The two electromagnets 5 keep a preset distance when the power is off, and the two electromagnets 5 generate mutual attraction force when the power is on to close and combine. After two electromagnets 5 draw close and merge, can make two elastic rubber blocks 3 draw close through two connecting rods 6 respectively to the increase is to spacing arm 1's centre gripping dynamics.

In this embodiment, controller 4 can be connected with vehicle control unit electricity, vehicle control unit is the total controller of vehicle itself, vehicle control unit can detect the aperture information of door through other electrical components (like door aperture sensor), when the door opens to predetermineeing the aperture under the effect of electromagnetic thrust, vehicle control unit gives controller 4 with signal transmission, controller 4 controls two electro-magnets 5 circular telegrams again, then produce the extrusion force to two elastic rubber piece 3 through two connecting rod 6 respectively, thereby the increase is to spacing arm 1's centre gripping dynamics, thereby make the door park steadily at predetermineeing the aperture position. The preset opening degree can be set by background workers according to actual conditions. When the vehicle door is parked, the electromagnet 5 is powered off, and people can select to continue to enlarge the opening of the vehicle door or close the vehicle door.

In the embodiment, a plurality of gear grooves 7 are formed in the limiting arm 1, and the gear grooves 7 are arranged along the length direction of the limiting arm 1; one side of the elastic rubber block 3 extruding the limiting arm 1 is provided with a convex structure matched with the gear groove 7. When the protruding structure moves to the position of the gear groove 7, the protruding structure can sink into the gear groove 7, so that the vehicle door is provided with an obvious pause and contusion feeling, and the vehicle door is prevented from continuously expanding the opening. And the predetermined aperture in this embodiment can with from spacing box 2 nearest gear recess 7 corresponding, open when the door to predetermined aperture, elastic rubber block 3's protruding structure just also moves to in spacing box 2 nearest gear recess 7, make protruding structure and gear recess 7 meet the pause of production feel and apply the clamping-force of giving elastic rubber block 3 mutually supporting with electro-magnet 5, further make the door can be smoothly at predetermined aperture department parking, strengthen the reliability of this stopper.

In this embodiment, the stopper still includes protection box 8, and spacing box 2, connecting rod 6 and electro-magnet 5 all encapsulate in protection box 8, and spacing arm 1 runs through protection box 8, and wherein, one side of spacing box 2 is fixed on protection box 8's inside wall. The protective box 8 may be a metal box. Through setting up protection box 8, play the guard action to spacing box 2, connecting rod 6 and electro-magnet 5, reduce connecting rod 6 and electro-magnet 5 and receive the risk of destruction, also make the appearance of this stopper more pleasing to the eye simultaneously.

In this embodiment, the stopper further includes a sliding installation shell 9, and the sliding installation shell 9 is an annular shell. The electromagnet 5 is a cylindrical structure matched with the annular shell. Two electromagnets 5 all slidable mounting in the installation shell 9 that slides, and the installation shell 9 that slides can be fixed on the lateral wall of spacing box 2, also can fix on the inside wall of protection box 8. Through setting up installation shell 9 that slides, play installation and spacing effect to electro-magnet 5 for two electro-magnets 5 can draw close smoothly when the circular telegram, strengthen the compactness of this stopper structure.

In this embodiment, a connecting plate 10 is fixed to one side of the protection box 8, the connecting plate 10 has at least two first connecting holes for bolts to pass through, and the connecting plate 10 can be fixed to the door inner panel 15 by bolts, so as to fix the protection box 8 to the door inner panel 15. One end of the limiting arm 1 is hinged with a mounting base 11 through a pin shaft, the mounting base 11 is provided with at least two second connecting holes for bolts to pass through, and the mounting base 11 is fixed on the vehicle side wall 14 through bolts, so that the limiting arm 1 is hinged with the vehicle side wall 14. In addition, a limiting head 12 is fixed at the other end of the limiting arm 1, and the limiting head 12 can limit the limiting arm 1 to be separated from the protection box 8; and when the vehicle door is opened to the maximum opening degree, one end of the limiting head 12 of the limiting arm 1 can abut against the protection box 8, so that the vehicle door is prevented from continuously expanding the opening degree.

In this embodiment, a controller interface 13 is arranged on one side outside the protection box 8, and the controller 4 is installed at the controller interface 13 of the protection box 8, so that not only can a line conveniently pass through, but also a worker can conveniently install and detach the controller 4.

Example two

A vehicle comprises a vehicle body and a stopper mounted on the vehicle body, wherein the stopper is the stopper in the first embodiment. The door installed on the vehicle body is a door without a handle, and the door is opened by electromagnetic driving force. When the door was opened to predetermineeing the aperture under the effect of electromagnetic thrust, vehicle control unit transmitted the signal for controller 4, and controller 4 again controls two electro-magnets 5 circular telegrams, then makes two elastic rubber piece 3 draw close through two connecting rod 6 respectively, and the increase is to spacing arm 1's centre gripping dynamics to make the door park steadily in predetermineeing the aperture position.
