Abstract
The utility model discloses an automobile door limiting device which comprises an limiting arm and a rubber spring, wherein the rubber spring is arranged in an limiting case, one end of the limiting arm extends into the limiting case, penetrates through the rubber spring and the limiting case and is fixedly connected with a rubber boss, the other end of the limiting arm is fixedly connected with a side wall of an automobile through a metal connecting member, and the width of the portion where the limiting arm is near the limiting case is larger than that of the portion where the limiting arm is near the metal connecting member. A straight-shaped limiting arm structure of an existing automobile door limiting device is modified into the structure which is provided with a certain slope and is tapered in gradual transition, thus, the limiting device cannot exert resistance on an automobile door continuously in the process of the door closing and opening, the resistance is only generated at a certain point or on a certain small distance, under the same resistance, the shorter the action distance of the resistance is, the less the required energy consumption is, then the outside provides less force under the condition of the same door opening/closing speeds, the force is the limiting force of the limiting device, so that the limiting force is less, and the comfort of the door opening/closing is improved.
Description
Technical field
The utility model relates to auto parts and components, is specifically related to a kind of automobile door stopper.
Background technology
Automobile door stopper is one of major part in the body accessories.Along with the progress of society, development of science and technology, people are increasingly high to the quality requirements of automobile, and like the comfortableness of opening-closing door, whether the comfortableness of opening-closing door quality meeting sometimes directly influence client and can buy.So the comfortableness that promotes the automobile opening-closing door also will become an important topic that promotes in the automobile quality.And the spacing power of stop plays crucial effects to the comfortableness of vehicle switch door.General automobile door stopper is made up of position limit arm and position-limited box, wherein is provided with rubber spring in the position-limited box.Position-limited box is fixed on the car door, and position limit arm passes position-limited box, directly with position-limited box in rubber spring contact, position limit arm one end is fixed on the gusset, the other end has a rubber boss structure, this structure can guarantee that position limit arm can move and do not deviate from position-limited box.Car door is in the opening and closing process, and position limit arm can move in position-limited box, can produce frictional resistance between the rubber spring in the moving process in position limit arm and the position-limited box, and this resistance is exactly the important component part in the resistance in switch door process, experienced of people.Under the identical situation of other conditions, the structure of position limit arm directly influences the size of this frictional resistance.General position limit arm structure is a flat, in the opening-closing door process car door is applied resistance always, and the spacing power of this kind structure is bigger, will feel in the opening-closing door process that resistance is bigger, and therefore, the comfortableness of opening-closing door is relatively poor.
Summary of the invention
The purpose of the utility model provides a kind of automobile door stopper, and it can reduce the resistance in the opening-closing door process, improves the comfortableness of opening-closing door.
The described a kind of automobile door stopper of the utility model; Comprise position limit arm, position-limited box and be located at the rubber spring in the position-limited box; One end of said position limit arm stretches into position-limited box and passes that rubber spring is fixedly connected with a rubber boss with position-limited box, the other end is fixedly connected on the vehicle side through metal connecting piece, it is characterized in that: said position limit arm near the width at position-limited box position greater than width near the metal connecting piece position.
The position limit arm structure that the utility model will have the flat of automobile door stopper now changes band certain slope, descending progressively transitional structure into, and like this, stop just can not apply resistance to car door always in the opening-closing door process; And just produce resistance in certain any or certain a bit of distance; Under the identical situation of resistance, the distance of drag effect is short more, needs the energy of consumption just more little; The power that the external world need provide under equal opening-closing door speed is also just more little; This power is exactly the spacing power of stop, so spacing power is also just more little, thereby has improved the comfortableness of opening-closing door.
Description of drawings
Fig. 1 is the structural representation of existing automobile door stopper;
Fig. 2 is the structural representation of the utility model.
The practical implementation method
Below in conjunction with accompanying drawing the utility model is further described.
Referring to a kind of automobile door stopper shown in Figure 2; Comprise position limit arm 2, position-limited box 3 and be located at the rubber spring 4 in the position-limited box; One end of said position limit arm stretches into position-limited box and passes that rubber spring 4 is fixedly connected with a rubber boss 5 with position-limited box, the other end is fixedly connected on the vehicle side through metal connecting piece 1, it is characterized in that: said position limit arm 2 near the width at position-limited box position 6 greater than width near metal connecting piece position 7.
Car door is being opened or is closing in the closed procedure; Position limit arm 2 can move in position-limited box 3; Can produce frictional resistance between the rubber spring 4 in the moving process in position limit arm 2 and the position-limited box 3, this resistance is exactly the important component part in the resistance in the opening-closing door process, experienced of people.Under the identical situation of other conditions, the structure of position limit arm 2 directly influences the size of this frictional resistance.The utility model under the position limit arm situation constant near position-limited box position 6 Breadth Maximums reduces the width of position limit arm near metal connecting piece position 7 keeping, and is optimized for by straight line and circular arc is tangent and transitional structure progressively by straight broken line syndeton; The resistance that rubber spring 4 in the opening-closing door process in 2 pairs of position-limited box 3 of position limit arm applies is incremental, from small to large; Rather than apply maximum resistance always, so suffered resistance summation is just more little in the opening-closing door process, under the identical situation of stroke; Resistance is more little; The energy of required consumption is just more little, and the power that the external world need provide under equal opening-closing door speed is also just more little, and this power is exactly the spacing power of stop; Be that spacing power is also just more little, thereby improved the comfortableness of switch door.
Referring to existing automobile door stopper shown in Figure 1; Because the position limit arm 2 of existing automobile door stopper equates with width near metal connecting piece position 7 near the width at position-limited box position 6; So; Rubber spring in the opening-closing door process in 2 pairs of position-limited box 3 of position limit arm just applies maximum resistance always, and therefore, the comfortableness of opening-closing door is relatively poor.
Claims (1)
1. automobile door stopper; Comprise position limit arm (2), position-limited box (3) and be located at the rubber spring (4) in the position-limited box; One end of said position limit arm stretches into position-limited box and passes that rubber spring (4) is fixedly connected with a rubber boss (5) with position-limited box, the other end is fixedly connected on the vehicle side through metal connecting piece (1), it is characterized in that: said position limit arm (2) near the width of position-limited box position (6) greater than width near metal connecting piece position (7).
